• See her page here for more details.

Edwin Black

• See his page here for more details.

Ingrid

• See her page here for more details.

Kiryuu Sabato

The Chief-Scientist for Edwin Black's organization, NOMAD. Originally a human scientist who study the "dark arts", he was killed by Murasaki, but was revived as a demon thanks to his underlings. Kiryuu now plans to overthrow Black for leadership.

• 0% Approval Rating: Whether he is working for NOMAD or the Taimanin, everybody hates him, and only keeps him around because his skills are too useful to lose, and even that has it's limits.
• Ascended Extra: Was mentioned as the scientist responsible for Asagi and Sakura’s body modifications in the first game. However, at the time, Kiryuu didn't even have a character sprite. He is now a major recurring character in the franchise.
• Asshole Victim: In the OVA. Both Edwin Black and Ingrid feel no guilt in disposing him. Granted, Black already knows that Kiryu's been scheming behind his back, and Ingrid pays him back for all the pain he inflicted on her.
• Awesomeness By Analysis: Utilizes this to learn the demonic equivalent of optic camouflage from Ingrid.
• Big Bad: For Taimanin Murasaki (even though most of it was told through his point of view) and the Hell Knight Ingird OVA.
  • Big Bad Duumvirate: With Ingrid in Taimanin Murasaki. For most of story Kiryuu serves as the main antagonist from Murasaki's point of view, while Ingrid serves as the main antagonist from Kiryuu's point of view.
• Combat Tentacles: When he is not using them as Naughty Tentacles.
• Death by Adaptation: Was killed off at the end of Hell Knight Ingrid, but is still alive and well in the visual novel series (being forced to work under the employment of the Taimanin organization).
• Enemy Mine: Even though he's on the good guy side in the third game, he's basically been press ganged into it after surviving his debut game, where he lost his bid for power and was captured by the Taimanin. However, they needed his skills, and he needed their protection since his failure meant he was nothing but a target for his former employers, and he's smart enough to realize pissing off his only remaining source of protection is far too dangerous.
  • In the canon ending of TM, Kiryuu forces Murasaki to team up with him to escape NOMAD's forces lead by Ingrid. In exchange Kiryuu would turn himself over to the Taimanin and ensure Sakura's safety.
• Expy: Cast in a similar mold as Professor Hojo for being both amoral, bispectacled mad scientists who have no qualms in experimenting both humans and monsters alike to further their plans. Not to mention they both fantasize of godhood and transform into monstrous forms once confronted by their respective adversaries. The fact that his Evil Plan in Hell Knight Ingrid involves forcing the heroines to mate with a dog-like creature seems very similar to what Hojo try to do with Aerith and Red XIII.
• Faux Affably Evil: Tries to present himself as a respectable scientist and aristocrat, but it never last as his sadistic nature and Jerkass tendencies tend to get the better of him.
• Fusion Dance: With Murasaki during the canon ending of TM. He basically transfer his consciousness into her body, so Murasaki's outward appearance remains the same. In this state, Kiryuu can Power-Up Murasaki's ninja abilities, give her access to his Combat Tentacles, and Spontaneous Weapon Creation abilities.
• Half-Human Hybrid: Technically, his body is still human, but demonic power has reanimated him and he's now a semi-immortal demon who still retains his human form by default.
• Hate Sink: Even worse than Oboro in the OVA.
• Healing Factor: It's possible to kill him even as a demon, but his healing power as a demonic being is high enough he's have to be utterly obliterated in one shot to make sure the death took, as he takes a punch that caves in half his skull at the beginning of the third game and heals back completely from it, shrugging it off as mild injury.
• Hellish Pupils
• H-Game POV Character: Type VI; A for Taimanin Murasaki.
• Hostage Situation: Throughout TM, Kiryuu was able force Murasaki to do his bidding by placing an organic Explosive Leash on Sakura and threatening to kill her if Murasaki doesn't compile. During the climax of the visual novel, Kiryuu offers Sakura's safety in exchange for Murasaki to pull an Enemy Mine.
• I Have You Now, My Pretty: Murasaki tends to be his favorite target.
• In Love with Your Carnage: Towards Murasaki.
• Karma Houdini: In the visual novel. Considering this guy is a rapist who subjugated countless innocent women to be Sex Slaves, being forced to work for the Taimanin and being put under house arrest at their headquarters seems like just a slap on the wrist.
  • The writers of the series apparently realized this, which is why before the end of the first act his former mentor Furst subjects him to a horrifically slow death he only escapes due to a hidden backup plan and redeems himself further by foiling the attempt to take Asagi out, now having even more reason to never try going back to the bad guy side..
• Mad Scientist
• The Medic: Both in the traditional sense and that after joining the Taimanin, he is usually the one put in charge of undoing an sexual Bio Augmentation that have been done to the anti-demon ninjas.
• Jerkass: At his best. Even being on the good guy team doesn't do much aside from water down his sadism.
• Organic Technology: Many of his inventions tends to be this.
• Slap Slap Kiss: How he sees his and Murasaki's "relationship", even though she has no intention of getting beyond the beating the crap out of him part (which he enjoys).
• Spear Counterpart: Seems to be a male version of Oboro. Similarities include an obsession with a Taimanin that killed them in a previous life, being resurrected as a demon, and doing everything they can to make that Taimanin suffer.
• Stalker Shrine: You can see he's plastered a small one to the wall in his lab with a bunch of Murasaki pictures in the third game, though he doesn't have to actually stalk her.
• The Starscream: Plan to overthrow Edwin Black in both visual novel and in the OVA series, it doesn't work.
• Tall, Dark and Handsome: Once you get past his Slasher Smile and Combat Tentacles, he is actually a fairly decent looking man.
• Token Evil Teammate: For the Taimanins after his capture in the canon ending for Taimanin Murasaki. He was the one who undoes all the body modifications done to the Taimanins from previous installments and is forced to work under them in exchange for his life and protection from Edwin Black. He also seems happy with the fact that he gets to work alongside Murasaki, much to her dismay.
  • It's confirmed he works for the Taimanin in a similar fashion in Action Taimanin, and they still only keep him around because of his usefulness but still find him this trope at best. One notable difference is that he seems to have spun off his own Combat Tentacles ability and given Murasaki a variant of her own to use (without requiring a Fusion Dance), the exact circumstances of how to remain unknown thus far.
• Too Kinky to Torture: To the point that he'd be fine with Murasaki vivisecting him if she was the one doing so.
• Villainous Crush: On Murasaki, despite the fact she killed him when he was human.
• Villain Protagonist: Taimanin Murasaki was told mostly from his point of view and is technically the Big Bad of that story.

Nabelius

A Cerberus-like demon bio-weapon created by Kiryuu using Edwin Black's DNA.The creature only appears exclusively in the Hell Knight Ingrid OVA. Is most likely the only one of its kind produced, due to having no other appearances in the canon.

• Canon Foreigner: The demon only appeared in the Hell Knight Ingrid OVA.
• Crippling Overspecialization: The creature was made to specifically kill Edwin Black. Black was smart enough to not fight this creature directly, as he admits the hell hound will likely kill him. However, against any other opponents, like Kurou Yatsu, it's just another Mook.
• The Dragon: To Kiryuu in Hell Knight Ingrid.
• Explosive Breeder: According to Kiryuu, the demon is able to "mass produce" at an alarmingly fast rate. Kiryuu's Evil Plan was to force Ingrid and Murasaki to give birth to an army of these creatures and then use the horde of hell hounds to kill Black and take over Neo Tokyo. Luckily, the plan was stopped by Black and Kurou before it could be put into motion.
• Hell Hound: A 3 headed dog demon.
• Mars Needs Women: According to Kiryuu, Nabelius is capable of impregnating both human and demon women. It was about to mate with Ingrid and Murasaki, before being destroyed by Kurou.

Saya

Originally one of several Taimanins that went missing while investigating Tokyo Kingdom, she was apparently captured and turned into a Super Soldier by Oboro's clone. She now serves the clone, and helps Oboro in her plans to mentally break Asagi and Sakura so they can turn them into living weapons just like her.

• Adaptational Sexuality: She is portrayed as a Psycho Lesbian in Taimanin Asagi 2. However in Taimanin Asagi: Battle Arena, she portrayed as a Depraved Bisexual.
• Affably Evil: Saya is a genuinely polite person who doesn't hold any real malice toward the Igawa sisters. She even admits that she actually likes them. However, between her insanity caused by Oboro, and her desire to have a "sister" just like her, Saya isn't above tormenting them.
• Alas, Poor Villain: Saya’s final moment is surprisingly pitiful, and even Asagi (her killeress) felt bad for her. This is in spite of everything she has done to both her and Sakura.
• Back From The Dead: In RPGX, where she is brought back as Saya NEO.
• Beware the Silly Ones: Sure she might act like a goofy, yet polite, child most of the time, but she is still a depraved rapist.
• Climax Boss: Of TA2. Asagi is only able to defeat her by tapping into Kage's power for the first time. Saya's death serves as the final diverging point for game's many different routes.
• Combat Tentacles: Like Kiryuu's, they also have other... "uses" outside of combat.
• Creepy Child
• Cute and Psycho: She has the appearance of a cute girl, but is clearly insane.
• Cute Monster Girl: Even in her One-Winged Angel form, well the "human parts" anyways.
• Dark Action Girl: One of the few baddies on this list who are able to defeat Asagi in a fair fight.
• The Dragon: To Oboro's clone.
• Driven to Suicide: An invoked example in the visual novel of Taimanin Asagi 2; Oboro drove Saya to take her own life after mentally breaking her.
• Evil Counterpart: She's clearly one for Sakura, due to their similar personalities. Saya's habit of referring to Asagi and Sakura as "Onee-sama" or "Onee-chan" ("Big Sister") was likely given to her to reflected Sakura's status as Asagi's younger sister.
• Fallen Hero: She was a Taimanin before being experimented on by Oboro's clone.
• Genki Girl: Much like Sakura, however her energetic personalty comes off as more creepy than charming.
• Go Out with a Smile: Saya was actually happy that Asagi used her Super-Powered Evil Side, even though she used this power to kill her. She spent her final moments telling Asagi that she was happy to have met someone who can now truly understand her, even if it was just for a few seconds. True to form, Asagi did in fact feel bad for her, and saw Saya as just another victim to Oboro's clone.
• Hellish Pupils
• I Have You Now, My Pretty: Has done this to both Asagi and Sakura. Although it seems Sakura is her favorite target.
• Laughably Evil: She’s quite capable of being this due to her goofy nature.
• One-Winged Angel: Can turn into a powerful arachnid-like creature, complete with Combat Tentacles and Spider Limbs.
• Pointy Ears: A big indicator that she is a demon.
• Psycho Lesbian: Is only seen raping Sakura and Asagi in Taimanin Asagi 2, however her sexuality is changed in Taimanin Asagi: Battle Arena.
• Psychopathic Womanchild: She is around the same age as Sakura, but acts much more childish than her, which is saying something considering Sakura is already a Woman Child herself.
• Shadow Archetype: Represents what Asagi and Sakura might become if they give in to their inner demons.
• She's All Grown Up: "Saya Neo" in Taimanin Asagi: Battle Arena.
• Spared by the Adaptation: Although she was killed by Demon!Asagi near the end of Taimanin Asagi 2, she is still alive in the Taimanin Asagi: Battle Arena continuation. She is given an older appearance referred to as Saya Neo.
• Submissive Badass: Even though she is much stronger than Oboro's clone, she still chooses to be her underling. This is likely caused from the "conditioning" Saya had to go through when she was turned into the Oboro's Super Soldier.
• Super Soldier: Becomes this as a result of Clone!Oboro's experiments, and giving in to her hidden demonic powers.
• Tragic Monster: Was originally a Taimanin before she was captured, mentally broken from sexual torture, driven to commit suicide, and turned into a monster. (Though the part about her being forced to take her own life was taken out of TA2’s anime adaptation.) Also, her desire to turn Asagi and Sakura into living weapons wasn't necessarily formed out of malice, but instead a desire of wanting connect with someone who can truly understand her. Which would explain why she desperately wanted to turn Asagi and Sakura into her "sisters". Asagi even points out that she was just another victim.

Power Lady

The muscle-bound champion of the Chaos Arena.

• Adaptational Attractiveness: Inverted in the OVA. In the visual novels, her appearance is that of a Hot Amazon, however her character design was slightly altered in the OVA so that she would have a Face of a Thug.
• Alas, Poor Villain: In-Universe, Asagi find herself pitying Power Lady after watching her be forced to be a Sex Slave for a group of orcs.
• Babies Ever After: Although we never actually see her pregnant, the narration claims Power Lady ended up impregnated with an orc child during her final H-scene in TA3.
• Badass Normal: A Dark Action Girl variation. Its revealed in TA3, that she actually a completely normal human, but she can still put up a fight against Asagi, granted only after Asagi is given a Drama-Preserved Handicap.
• Big No: Power Lady gives several when Asagi gives her a taste of her own medicine.
• The Brute
• Cleavage Window
• Dark Action Girl: Being both a villain and professional fighter for the Chaos Arena.
• Evil Laugh: Does several if she beats Asagi in their rematch.
• Expy: To Power Girl. Parallel include a Hot Amazon that wears a white Leotard of Power with Cleavage Window and has shoulder length blonde hair.
• Facial Markings: All one has to do is closely inspect her face to see that her "mask" is in fact several facial tattoos.
• Hot Amazon: The most muscular woman in the series so far, and is consider fairly attractive both in and out of series.
• Human Mom, Non-Human Dad: She apparently ends up being impregnated with an orc child the last time we see her in TA3.
• Leotard of Power
• Lightning Bruiser: She’s obviously strong and is pretty fast to boot.
• Mythology Gag: While Power Lady forced Asagi to take in a large dildo in both the visual novel and the OVA, the dildo in the OVA was enormously larger than one in the visual novel. In TA3, the dildo was the same size as it was in the OVA.
• No-Holds-Barred Beatdown: Nearly all of Asagi's encounters with her would normal lead to her being on the receiving end of this. However, she was able to get her revenge on Power Lady in Taimanin Asagi 3.
• Only Known by Their Nickname: Like all fighteresses at the Chaos Arena, she is only known by her stage name, "Power Lady".
• Psycho Lesbian: If her sexually assaulting Asagi in LILITH-IZM 02 ~ Internal Cum Impregnation is anything to go by.
• Sex Slave: In Taimanin Asagi 3, she was forced to be this for a group of bobtrolls as punishment for losing to Asagi in the Chaos Arena.
• Sexual Karma: In TA1 and its OVA adaptation, Power Lady forced Asagi to take in a enormously large dildo as a "penalty game" after she lost to her in the Chaos Arena. During their rematch in TA3 (the visual novel) however, Asagi can force Power Lady to endure the same "penalty game" that she forced upon her. Additionally, Edwin Black sentenced Power Lady to be a Sex Slave for a group of orcs as punishment for her failure. To top it all off, the narration states that the orcs were able to impregnate her.
• Sore Loser: If Asagi beats Power Lady in their rematch, the latter refuses to accept it.
• Villainous Breakdown: She did not take being defeated by Asagi and receiving Sexual Karma very well. Also, the latter caused her to become mind-broken.
• Wrestler in All of Us: She is a professional fighteress in Chaos Arena.
• You Have Have Failed Me: On the receiving end of this after losing her fight to Asagi in TA3. Edwin Black gave her to a life sentence as Sex Slave to a horde of orcs and bobtrolls for her failure.
• Zettai Ryouiki: Grade B.

Kaliya/Snake Lady

Another fighteress from the Chaos Arena and a henchwoman for Oboro.

In the Taimanin Asagi ZERO timeline, she is the proprietress of the Chaos Arena and is one of Edwin Black's lieutenants. Additionally, her human appearance is only a disguise and she is actually one of the three chiefs of the Naga (snake demons) with powers that rival Edwin Black's.

• Absolute Cleavage: One of her outfits in TA0.
• Adaptational Badass: In the original timeline she was just a simple henchwoman, while in TA0's new timeline, her powers has been stated to rival Edwin Black's.
• Animal Motifs: Snakes, obviously.
• The Baroness: Like Oboro, she is the sexpot variation.
• Big Bad: Of Taimanin Asagi ZERO.

• The Bus Came Back: After being absents for most of the franchise, except for cameos, she returns in Taimanin Asagi ZERO.

• Cool Mask: Part of her new outfit in ZERO.
• Cute Monster Girl: She is a snake demon that looks attractive in both her human and naga forms.
• Dark Action Girl: Three words: Taimanin Asagi ZERO. For details, see Adaptational Badass above.
• Death Glare: Gives several of these to Asagi in ZERO.
• Depraved Bisexual: In Taimanin Asagi: Battle Arena shows that she sexually assaults both men and women.
• Faux Affably Evil:
• Hermaphrodite: A classic futanari example. Although you can't really tell when she is clothed, even in her most revealing outfits.
• Karma Houdini: One of the few villains that has yet to suffer any consequence for her actions toward Asagi. This is finally subverted, after many years, in Taimanin Asagi: Battle Arena and Taimanin Asagi Zero, although she is still alive in both stories.
• Lecherous Licking: Does this to both Asagi and Sakura.
• Mud Wrestling: Mostly fights in these, but with oil instead of mud.
• Never My Fault: Blames Asagi for destroying the Chaos Arena’s entry, even though her own fighting energy mainly begot it.
• One-Winged Angel: She changes into her Naga form during her final fight with Asagi in ZERO and in her boss fight in Action Taimanin.
• Only Known by Their Nickname: As a fighteress from the Chaos Arena, she is only known by her stage name, "Snake Lady". In TA0 however, her real name is Kaliya.
• Overly Long Tongue: Fits well for her Animal Motifs.
• Poisonous Person: Being a snake demon.
• Psycho Lesbian: Although she is a Hermaphrodite, she is mostly female, and still has her way with Asagi and Sakura. Although in Taimanin Asagi: Battle Arena she portrayed as a Depraved Bisexual.
• Sexual Karma: Ends up being raped by orcs in Taimanin Asagi: Battle Arena.
• Snake People: She is a Naga/snake demon, who can freely change between her human form and Naga form.
• Snakes Are Sexy: She is a snake demon in a Hentai.
• The Sociopath: Need for stimulation? Check. Remorseless? Check. Unethical? Check. Unempathetic and sadistic? CHECK!
• Stripperiffic: Revealing even by this series standards. Although her new outfits in ZERO are more concealing.
• Taken for Granite: One of her new powers in TA0.
• Villain: Exit Stage Left: After being gravely injured by Asagi in TA0 in the Golden Ending, Snake Lady escapes when Oboro Koukawa appeared while Edwin Black was controlling her body.
• Villainous Breakdown: She experiences several of these in ZERO.
  • When fighting Asagi for the first time, Snake Lady loses her cool when the Igawa sister managed to deal an injury to her hand. She regains her composure fairly soon afterwards though.
  • In ZERO’s Golden Ending, Snake Lady becomes irate when Asagi starts to fight her without the hindrance of the Demon Seed. She manages to regain some of her composure when upon deciding to have Byg petrify Sakura. However, once that failed (courtesy of Murasaki), Snake Lady starts to drop her bundle.
• Villainous Crush: On Asagi and Sakura, she even takes the latter's virginity in TA0's timeline. She wants to force both sisters into a life of sex slavery as a "matching set".
• Would Hurt a Child: Snake Lady has no qualms toward harming Asagi and subjecting Sakura to Cold-Blooded Torture, even though they are teenagers in ZERO. Not to mention that she had a child kidnapped and threatened Sakura that she would kill him and “make him suffer a lot” unless she fought her.
• Wrestler in All of Us: She mostly uses wrestling moves when fighting in her human form.
• Yellow Eyes

Booker Walls

A low-ranked demon who acts as an informant and information broker for the Taimanin. He has worked with Asagi for years and developed an unhealthy attraction towards the Almighty Taimanin. Booker has been biding his time to kidnap Asagi when she is at her weakest and force her to be his "wife."

• Abduction Is Love: Kidnaps Asagi due to his unhealthy crush on her. In bad ending, the two become a couple after he successfully breaks her.
• And Now You Must Marry Me: His only real goal is to kidnap Asagi so that she could be his "wife". The guy is so delusional that he doesn't really do anything to make their "marriage" official (aside from his The Baby Trap ploy). He just starts referring to himself as Asagi's "husband" shortly after kidnapping her.
• Babies Ever After: In Taimanin Asagi Gaiden: Summer Days' bad ending route where he is able to successfully impregnate Asagi, Sakura, and Murasaki.
• The Baby Trap: Believes that Asagi will have to stay with him after kidnapping her if he is able to knock her up. Granted, any woman that he does impregnate seems to be doomed to become his mind broken slave.
• Big Bad: Of Taimanin Asagi Gaiden: Summer Days.
• Big Bad Ensemble: With the dark beast/majuu in Taimanin Asagi Gaiden: Summer Days. The two demons were working independently of each other, but the dark beast/majuu's role of causing Asagi and her friends to temporary lose their powers did work in Booker's favor.
• Boring, But Practical: His evil plan is just to wait until Asagi is weakened from a mission, such as losing her powers after being exposed to the blood of a dark beast/majuu, and then kidnap her when she is off the clock. This is much more straightforward than the overly complex schemes the other villains tend to make. Asagi even lampshades that his plan wasn't really well thought out. Still, it was possible for him to successfully "break" and enslave Asagi, Sakura, and Murasaki thanks to their powerless state and the body modifications done to them from previous adventures, as shown in the game's bad ending.
• Even Evil Has Loved Ones: A very twisted example. Booker deluded himself into believing that he can be a part of Asagi's family, seeing Asagi as his "wife" and Sakura as his "sister". He does seem to get his wish after he turns Asagi, Sakura, and Murasaki into his subservient sex slaves and he impregnated which of them in the bad ending route. At the end of the route, Booker promises to take care of the 3 for the rest of their lives and does seem to genuinely care about his unborn children that the former Taimanin are carrying.
• Explosive Breeder: Considering he has little trouble knocking up Asagi, Sakura, and Murasaki in the bad ending route, and the unnaturally quick gestation cycle of his children, he definitely can be this.
• Express Delivery: Any woman he knocked up is expected to give birth in just a matter of days instead of months. This is proven in the bad ending route when Asagi, Sakura, and Murasaki were shown in the late stages of pregnancy less than of week after he impregnated them.
• Fat Bastard: He is an evil rapist and a has big pot belly.
• Filler Villain: Booker has no real connection to the Myth Arc of the series, and is just a one-shot villain for Asagi to defeat during the Beach Episode of the visual novels.
• Gonk: Being a short, orc-like demon who is covered in warts. He is stated to be very ugly, even by demon standards.
• Impaled with Extreme Prejudice: How Asagi kills him in the Golden Ending route, by impaling him in the chest and head with stalactites.
• Interspecies Romance: With Asagi in the bad ending where she becomes his mind broken slave. To a lesser extend, he has this with Sakura and Murasaki after "breaking" them.
• Lone Wolf Boss: Booker isn't a part of NOMAD or any other villainous organization, he is just a creepy Stalker with Crush that was acting on his own. He also had nothing to do with dark beast/majuu that caused Asagi, Sakura, and Murasaki to lose their power, which resulted in the advents of the game.
• Love Makes You Crazy: He was a decent informant for the Taimanin for many years, until his crush on Asagi becomes too much for him and decides to kidnap her.
• Marry Them All: In Taimanin Asagi Gaiden's bad ending, where he is able to successfully "break" and impregnate Asagi, Sakura, and Murasaki, resulting in all 3 women becoming his Sex Slaves. However, he only refers to Asagi as his "wife".
• The Napoleon: He is stated to be only half as tall as Asagi, and is definitely not a nice person.
• Naughty Tentacles: He is capable of sprouting tentacles all over his body, where his warts are.
• Mars Needs Women: Being a demon that is attracted to human women.
• Not Blood Siblings: A rather creepy example as he refer to Sakura as his "sister" after kidnapping Asagi, although that doesn't stop him from raping her. In the bad ending route, the mind broken Sakura accepts Booker as her honorary "brother" despite being pregnant with his child.
• Not-So-Harmless Villain: Despite not being the smartest or most powerful demon, he was clever enough to wait to kidnap Asagi and her allies when they were at their weakest. He would have been able to turn them into his mind broken slaves if Asagi didn't use her Herioc Willpower to revitalize her ninja powers.
• Sickeningly Sweethearts: With Asagi, Sakura, and Murasaki in the bad ending route, which is meant to show how truly far gone the former Taimanin were after he "broke" them.
• Stalker with Crush: To Asagi. The guy has been waiting years for the perfect opportunity to kidnap Asagi and force her to "marry" him.
• Tiny Guy, Huge Girl: The "Tiny Guy" to Asagi's "Huge Girl", if only because of how short he is.
• Ugly Guy, Hot Wife: The "Ugly Guy" to Asagi "Hot Wife" in the bad ending where they end up together.
• Villainous Crush: On Asagi, and to a lesser extent, Sakura and Murasaki.
• Weak But Skilled: Although Booker is one of the weakest demons around, his true skill comes from his ability to gather information. According to Asagi, he was a very useful informant in the past. He has been keeping tabs on Asagi for years, just waiting for the perfect opportunity to abduct her. He finally got his chance when Asagi temporary lost her powers, and was relocated to a remote area for recovery.
• Xanatos Speed Chess: Booker is an impulsive, opportunist who, unlike previous main antagonists, did seems to plan things out all the way through. His original goal was to quietly abduct Asagi when she was left powerless from an unrelated mission. However, when Sakura and Murasaki came to investigate the cave he was finding in, he was forced to attempt to kidnap them as well. In the Golden Ending route, this would prove to be Booker's downfall as hearing her loved ones in trouble caused Asagi to use her Heroic Willpower to revitalize her power and kill Booker. In the bad ending route where Asagi gives up, Booker at least seem to have planned out his escape route, and was able to successfully take all 3 women with him without being tracked.

Fukumen Sugata no Onna Senshi

A cat-themed fighter from the Chaos Arena.

• Animal Motifs: Seemed to be one for cats.
• Bit Character: Out of all the fighters from the Chaos Arena, she has by far the least amount of screen time. Her only major scene in TA1 was strangling Asagi when she had her in a headlock. She appears again in TA3, but only as a background character during the Chaos Arena's "opening ceremony".
• Cool Mask: Wears a black leather mask. It give her a cat-like appearance.
• Expy: She is clearly based on Catwoman, but with a much more revealing get up.
• Hot Amazon: She much more muscular than Asagi, but not as buff as Power Lady.
• Karma Houdini: Has yet to suffer any punishment for her actions, although this is largely due to being put Out of Focus.
• Psycho Lesbian: Implied.
• Stripperiffic: Her wrestling outfit in basically just a black bikini, stockings and gloves.
• Wrestler in All of Us: Like Power Lady and Snake Lady, she is a skilled wrestler.
• Zettai Ryouiki: Grade A.

Furst

A Mad Scientist and former mentor to Kiryuu. In Taimanin Asagi 3, he takes over his former student's position as the chief scientist of NOMAD after Kiryuu's capture in Taimanin Murasaki. Like Kiryuu, Furst plans to overthrow Black for leadership.

• Asshole Victim: Was killed by Oboro after his attempted double-cross, and nobody shed a tear.
• Big Bad Wannabe: He wanted to be the main villain of TA3, and while he was indeed a creditable threat, Oboro and Edwin Black have him beat in terms of cunning and powers.
• Bullying the Dragon: Trying to double-cross Oboro wasn't his smartest move.
• Chronic Backstabbing Disorder: He's worse than Kiryuu in this regard.
• Evil Counterpart: Technically, "eviler counterpart" for Kiryuu.
• Fat Bastard
• Hoist by His Own Petard: Furst was slayed by his very own injuu after Oboro gained control over it.
• Mad Scientist
• The Mentor: Was one for Kiryuu.
• Organic Technology: Much like his former student, Furst specialized in creating these.
• The Starscream: Helps Oboro with her plans to brainwash Ingrid and eventually overthrow Edwin Black. Later he tried to double-cross her, but that didn't end well for him.
• Suspiciously Similar Substitute: Pretty much takes over Kiryuu's role now that his former student is working for the Taimanins.
• Villains Want Mercy: Pathetically begs Oboro for mercy when she turns the tables on him.

Dogle

An orc who works for NOMAD. He is the leader to a horde of orcs that acts as NOMAD's "muscle". In one of the Bad Endings of Taimanin Asagi 3 and its anime OVA, Asagi was forced to marry him after she becomes a mind broken Sex Slave for the evil organization, and together the two have an orc child name Big.

• And Now You Must Marry Me: In one of the bad endings of TA3, Corrupted Sakura and Murasaki (and Oboro in the anime) forces Asagi to marry the orc and have him impregnate her, purely For the Evulz. Although due to her mental re-conditioning (with a slight hint of More Than Mind Control), Asagi ends up falling in love with her orc husband.
• Anime Hair: Has Saiyan-like spiky hair.
• Babies Ever After: In one bad ending in TA3 and the anime OVA, where he impregnates Asagi with his child.
• Biggus Dickus: He a large orc in a Hentai, so naturally.
• The Brute: He and his horde of orcs serves as this to NOMAD throughout TA3.
• Demoted to Extra: In the anime OVA of TA3 where he only appears for one scene, while in the visual novel he is a recurring villain.
• Even Evil Has Loved Ones: For what's it worth, in the visual novel's ending where he marries Asagi, he does seem to love his wife, and cares for their son, Big.
• Fat Bastard: He has a noticeable gut and is an evil orc.
• Happily Married: To Asagi in the anime and in a possible bad ending in TA3, as the two do act like a lovey-dovey couple. Although lets not forget that Asagi is only fawning over the orc because she was driven insane by Oboro, Corrupted Sakaru, and Corrupted Murasaki, and was brainwashed to be a lustful nymphomaniac, and by extension Dogle's semi-devoted wife.
• Human Mom, Nonhuman Dad: The "Nonnhuman Dad" to Asagi's "Human Mom" for their son, Big.
• Interspecies Romance: With Asagi in the endings where he marries her, as she is human and he is an orc. However, their "romance" only came to be as a result of Asagi giving into her brainwashing, and otherwise would have never happened.
• Mars Needs Women: Being an orc that is attracted to human women, particularly Asagi.
• Our Orcs Are Different: Like other orcs in the Taimanin series, he is a brutish, but intelligent, monster that is capable of reproducing with human women.
• Red Eyes, Take Warning: Like most other orcs in this series.
• Third Option Love Interest: Throughout TA3, its been built up that Asagi would end up with Kousuke or Edwin Black. However, in one of the bad endings in the visual novel and in the anime, Asagi winds up marrying this monster.
• Ugly Guy, Hot Wife: In the endings where he marries Asagi. Being an orc, he is the "Ugly Guy" to Asagi's "Hot Wife".
• Unholy Matrimony: With Asagi after she become NOMAD's mind broken slave. In the visual novel, the two work under the Corrupted Sakura and Murasaki, and help them brainwash more Taimanin for Edwin Black.
• Villainous Crush: On Asagi.
• Walking Spoiler: Its rather hard talking about this monster without mentioning that he can become Asagi's potential husband in the TA3 visual novel and actually does become her husband in the anime.

Real

The operator of the most popular brothel in Yomihara, Under Eden. He is also the leader of a major prostitution ring, that is also named Under Eden. His brothel specializes in slave prostitutes, where the woman are forced to undergo body modifications to increase sexual pleasure and have magical brands placed on their tongues (lower abdominal in the OVA) that force them to obey his orders. These brands can cause pain, or in the worse case scenario, can cause the branded's limbs to exploded. He is also the one responsible for the disappearance of Shiranui Mizuki. In the bad ending routes it is revealed that he is Yazaki's brother.

• Adaptational Attractiveness: In the OVA, he shown to be fairly muscular with an average looking face. This is a sharp contrast to the visual novel, where he is an overweight Gonk.
• Arch Enemy: To Rinko.
• Big Bad Ensemble: Of Taimanin Yukikaze with Yazaki, his brother.
• Big Bad Wannabe: In the canon route, his plans are foiled by Asagi and Sakura before they even begin.
• Bigger Bad: Of the Lilith-Soft game, Ochiru Hitozuma, which takes place in the same universe as Taimanin Asagi. While Real, himself, doesn't actually make an appearance, his organization serve as the main villainous force of that game. They assisted the game's Villain Protagonist, Haruki Nagisa, with his goals to turn both his adoptive mother, Sayoko Natsume, and his teacher, Reiko Fuyuno, into slave prostitutes.
• Biggus Dickus: He quite well endowed and Rinko, in a state of sexual arousal during intercourse, even went as far as to call it "godly". This is taken to an almost comedic extreme in the Fallen Rinko route where the mind broken Rinko becomes obsessed with it, to the point of willing to do anything for Real.
• Demoted to Dragon: In TY2, it is revealed that Real and Yazaki have a boss, and was acting on his orders during the advents of TY1.
• Demoted to Extra: In TY2, as he only appears in flashbacks.
• Dirty Coward: In the canon ending, he released Yukikaze and Rinko from there magical Slave Brand when in the presence of Asagi and Sakura. This is a sharp contrast to smug attitude to the captive Yukikaze and Rinko.
• Dirty Old Man: Naturally, has to have at least one in any hentai franchise.
• Even Evil Has Loved Ones: Possibly his sole redeeming trait is that he does care about his brother and torments Yukikaze and Rinko because of what they did to him in TY1 opening. Just too bad Yazaki is just as much as a sadistic monster as he is. In the Fallen Rinko, he seemed to develop a fondness for Rinko after she has become his mind broken slave, giving her genuine compliment over her abilities to faithfully "serve" his every need.
• Fat Bastard: He has a noticeable pot belly and is stated to be over weight in the visual novel. Oddly enough, in the OVA this is subverted as he is given a muscular physique and visible abs.
• Faux Affably Evil: Tend to act like a respectful business man when Yukikaze and Rinko first met him. He tries to make the concept of the girls agreeing to be his Sex Slave sound like they were signing up for an extravagant job position. Naturally, his vile nature began to show the moment they sign the contracts.
• Gonk: Compare to the other rather attractive villains before him, this guy is downright ugly. Although this can be partly subverted depending on the adaptation.
• Horrifying the Horror: Briefly on the receiving end of this in the Fallen Rinko route where he is taken back by the mind broken Rinko's sexual desires. Ironic since he was the one who corrupted and depraved her in the first place.
• I Have You Now, My Pretty: Rinko seems to his favorite target.
• Karma Houdini: Downplayed. At the end of TY1, he releases Yukikaze and Rinko from their Slave Brands after being ordered to by the Igawa sisters in exchange for his life. The canon ending of TY1 ends with him getting a lightning blast in the face by Yukikaze, leaving him injured but alive. Currently, he is still at large after TY2.
• Know When to Fold'Em: In TY1's canon ending, when confronted by Asagi and Sakura after they sneak into Under Eden using Sakura's Casting a Shadow to travel through Zokuto's shadow, they gave him an ultimatum: release Yukikaze and Rinko from their Slave Brands and in exchange he gets to walk away alive. Real wisely, although reluctantly, agrees to the terms, and got to survive the game with only a non-lethal lightning blast to the face from Yukikaze.
• Mayfly–December Romance: In the non-canon Fallen Rinko route of TY, when he and the mind broken Rinko formed an Unholy Matrimony. Rinko stated to be old enough to be considered an adult, but still young enough to be in high-school, Real is a middle aged man that is possibly decades older than her.
• Non-Action Guy: Unlike most of villains list here, Real doesn't seem to have any combat abilities.
• Only Known By Their Nickname: Subverted. His name "Real" is just a alias, his actually named is revealed to be "Toshiji Yazaki" in TY's bad ending routes and in RPGX. He likely kept his true name a secret so that the Taimanin would not figure out his connection to his brother.
• Organic Technology: His "flesh vessel" which can release and disperse sperm, is filled with Naughty Tentacles (which was the only time this trope was used in Taimanin Yukikaze), and can endlessly rape someone for weeks, while keeping them alive by Force Feeding them with monster sperm. In one of game routes and in the OVA, Rinko had the misfortune of being placed in here for 2 week, which apparently drove her to madness, turning her into a submissive slave.
• Slave Brand: Not on him, he's the guy who brands his prostitutes with magical curse seals, forcing them to obey him.
• Soft Spoken Sadist: In the OVA series at least. Unlike Oboro and Kiryuu, who come off as Large Hams that take visible glee in tormenting the Taimanin they capture, Real usually talks in a compose, almost monotone, manner. Even when taunting and having his way with Rinko throughout the second episode, his expression almost looks bored throughout the whole thing. In the visual novel, he is a Large Ham like the rest of the villains.
• Spell My Name with an "S": Depending on the translation, his name could be spelled out as either "Rial" or "Ryal".
• Ugly Guy, Hot Wife: After him and a mind broken Rinko form an Unholy Matrimony in the non-canon Fallen Rinko ending. Although the proper term would be "Ugly Master, Hot Sex Slave".
• Unholy Matrimony: With Rinko in the non-canon Fallen Rinko ending, after she develops Stockholm Syndrome and becomes his personal slave.
• Villainous Crush: On Rinko. In RPGX, he also has one for Ingrid.
• You Got Spunk: In the non-canon bad ending routes, just before losing her virginity to him, Rinko declares her intention to making him pay once her magical Slave Brand in removed. Real just laughs this off and declares his own intentions to make Rinko "his woman".
• Younger Than They Look: Although he is still a middle-aged Dirty Old Man, he is apparently younger than Yazaki.

Muneichi Yazaki

The Chief Secretary of Civilian Affairs of the political party in control of the country. Influential in the criminal underground world of humans and demons. A corrupt politician that has been known to do secret under-the-table dealings with the demons. He is also a VIP customer for the Under Eden brothel. It is later revealed that Real is his brother.

• Abusive Parents: In a non-canon bad ending of TY1, the guy is perfectly fine with selling his own daughter(s) that he had with Shiranui and Yukikaze into sex slavery once they become of age.
• Adapted Out: Of the manga adaptation of Taimanin Yukikaze. In the manga's story, his brother was the sole mastermind to the False-Flag Operation to lured Yukikaze and Rinko into a trap.
• Arch Enemy: To Yukikaze. Although he see himself as one for Asagi.
• Batman Gambit: Although he can be rather incompetent in the canon route of TY, there is no denying that he was able to effectively pull this off against the Taimanin. All he had to do was to leak info on Shiranui's whereabouts in order to lure Yukikaze and Rinko specifically to Yomihara. He also seem to be aware that Asagi and other Taimanin would overestimate Yukikaze and Rinko's abilities to not personally check up on the two. His plan only really failed because Only Sane Man Tatsurou was able to convince Asagi to take a deeper look into the sketchy mission.
• Big Bad Ensemble: Along with Real, his brother, in Taimanin Yukikaze.
• Big Bad Wannabe: See himself as the main villain toward the Taimanin, however it was only through Real's manipulation were Yukikaze and Rinko captured. He later pales in comparison to the villains of Taimanin Yukikaze 2, and he gets killed in the sequel's Action Prologue.
• Corrupt Politician: Pretty much his entire shtick.
• Cyborg: His jaw is replaced with a mechanical one after Yukikaze kicked his original so hard that it did permanent damage.
• Demoted to Dragon: In TY1, Muneichi was clearly set up to be the mastermind who orchestrated Shiranui's disappearance and had Shiranui brainwashed to serve him. However, this is retcon in TY2, where his role as a cunning planner and Shiranui's "master" are instead given to far more dangerous Kuroi, while he becomes nothing more than a pawn who was following orders.
• Demoted to Extra: Goes from being the secondary antagonist of TY1, to being only an extremely minor villain in its sequel. He is also completely removed from the manga adaptation of Taimanin Yukikaze.
• Dirty Coward: Was only willing to confront Yukikaze, after Real placed a Slave Brand on Yukikaze, forcing Yukikaze to obey all of Real's orders.
• Dirty Old Man: He is a middle aged man that want to enslave a teenage Yukikaze.
• Even Evil Has Loved Ones: If nothing else, he get along with his brother, Real, even if both them are complete bastards.
• Fat Bastard: Like his brother, he has a noticeable pot belly.
• Gonk: He is drawn in a slightly different style compare to the Taimanin to highlight who unattractive he is.
• Harmless Villain: Even with all his political power, he is no real threat to the Taimanins. Yukikaze and Rinko chose to spare him in the Action Prologue because of this. The only reason he was able to have his way with Yukikaze in the Bad Ending Route(s) and in the OVA was because of Real.
  • Not-So-Harmless Villain: That being said, he still does many deplorable things to Yukikaze when she was forced to work for Under Eden. In the Bad Ending Route(s) it revealed that he arranged for Yukikaze and Rinko to be sent to Under Eden. However, in the canon route, his plan failed before it even began.
• I Have You Now, My Pretty: Yukikaze tends to be his favorite target.
• Mayfly–December Romance: In the non-canon Fallen Yukikaze, where he formed a relationship with the high-school aged Yukikaze after she has mind broken by her experience at Under Eden. The age gap is even wider than Real and Rinko.
• Non-Action Guy: Justified, seeing as he is a normal human.
• Polyamory: In the Fallen Yukikaze route in TY, both Shiranui and Yukikaze becomes his mistresses/slaves.
• Revenge: Wants revenge on Yukikaze, and to a lesser extend Rinko and Tatsurou, for ruining the meeting he was having with a group of demons during the prologue of the story.
• Smug Snake: Sees himself as Asagi’s Arch Enemy, even though that position belongs to the Fake Oboro and Edwin Black.
• Starter Villain: While he was part of a Big Bad Ensemble with Real in TY1, he only serves as the opening villain in TY2.
• Sudden Sequel Death Syndrome: In TY2, after finding out that Yazaki was the one who set them up in TY1 on a False-Flag Operation, Yukikaze and Rinko track him down at an airport and assassinate him in the game's Action Prologue.
• Ugly Guy, Hot Wife: He is a Gonk and his potential mistresses, Shiranui and Yukikaze, are much more attractive than him. Remember, he had to have these two women brainwashed to be with them, and those "relationships" are non-canon anyways.
• Unholy Matrimony: Forced Shiranui to be his brainwashed mistress and Yukikaze can also suffer the same fate if the non-canon Fallen Yukikaze ending is achieved in TY1.
• Unknown Rival: To Asagi. As he believes he is in a middle of a mental chess match against her. Asagi on the other hand, barely sees him as a threat, especially in the canon story-line where all his plans have fell part with little issues on her end.
• Villainous Crush: On Yukikaze.
• Villains Want Mercy: After Yukikaze and Rinko corner him in TY2's Action Prologue, Yazaki desperately begs for his life, first offering the millions of dollars that he was trying to run away with, and then information about Shiranui's whereabouts. Yukikaze responds by shooting him dead.

Slaver Zokuto

A slaver who engages in human trafficking. A member of the demon race who cooperates with the Taimanin in exchange for not being persecuted. He was commissioned by Asagi to smuggle Yukikaze and Rinko past the borders of Yomihara, and have the young Taimanins disguise themselves as prostitutes. However, he planned to betray them by selling them out to Real.

• Card Carrying Villain: He does not even try to hid his love for his "profession" and even openly describes himself as a "cheap bastard".
• Demoted to Extra: In the OVA adaptation. He doesn't even have a single line.
• Eye Scream: He is missing his left eye.
• Exact Words: Technically speaking, he never actually lied to the Taimanins. He inform the Taimanins that he could get them into Yomihara, but they would have to "act" like prostitutes once they are there. He also did get them to the man responsible for the disappearance of Shiranui Mizuki. The problem was that he left out some pretty crucial information, like that Yukikaze and Rinko would have to be slave prostitutes, as a opposed to willing ordinary prostitutes. In addition, they would be force to branded with magical Slave Brands that prevents them from rebelling, and that they would have to undergo body modifications.
• Fat Bastard
• Gonk: Like every other "Yukikaze villain".
• Jerkass: Even when he was acting as their ally, Zokuto couldn't help humiliating Yukikaze and Rinko any chance he got.
• Not-So-Harmless Villain: Although he is a Paper Tiger, he did successfully captured Yukikaze and Rinko for real as the two Taimanin were too naive to realize he is setting them up when they thought they were Trojan Prisoners.
• Our Orcs Are Different
• Paper Tiger: He might look intimidating, but he can't actually defeat a Taimanin in an actual fight.
• Sex for Services: In the bad ending routes of TY, Zokuto agreed to help Yukikaze and Rinko hide of truth of what has become of their mission from Tatsurou in exchange for having sex with them.
• Smug Snake: Acts sycophantic to Rinko and Yukikaze. However, after they become binded, he starts acting haughty toward them.

Unnamed Female Slaver

Another Slaver like Zokuto who engages in human trafficking. She is the person who ultimately subdue and captured Shiranui during her mission in Yomihara. After capturing the Taimanin, she sold Shiranui to Under Eden, thus kick starting the events of Taimanin Yukikaze 1 and 2. So far she has only appeared in the Taimanin Yukikaze OVA bonus episode.

• Absolute Cleavage: Much like Oboro's outfit.
• Animal Motif: Her outfit consist of bear accessories, for some reason.
• Animal-Eared Headband/Little Bit Beastly: Currently, it not entirely clear if her bear ears are her actual ears or just an accessory.
• Bit Character: She is only on screen for about less than 30 seconds and has yet to make another appearance in the franchise. That said, her capture of Shiranui is the what ultimately leads into the events of the Taimanin Yukikaze series.
• Canon Foreigner: Like Nabelius, she has only appeared in the anime OVAs.
• Combat Stilettos: Because Rule of Sexy.
• Combat Tentacles: Surprisingly, they been used purely for this, and haven't been used as Naughty Tentacles, at least not yet.
• Dark Action Girl: The fact that she was able to defeat Shiranui, a Taimanin whose powers rivals Asagi's, certainly makes her this. Granted, it did seem like she took Shiranui by surprise while the Taimanin was fighting an orc.
• Foil: Could be considered one to her fellow Slaver, Zokuto, as she captured Shiranui legitimately, while Zokuto was forced to used trickery to capture Yukikaze and Rinko who believed that they were Trojan Prisoners and let him bring them to Under Eden.
• Leotard of Power: Like many other characters in this series.
• Ms. Fanservice: Like many other female villains on this list.
• No Name Given: Her name has yet to be given.
• Shock and Awe: Her Combat Tentacles are capable of shooting needles that can generate electricity, which she uses to knock out Shiranui.
• Small Role, Big Impact: Despite her very limited screen time thus far, she is the Slaver that captured and sold Shiranui, making her largely responsible for everything that occurred in Taimanin Yukikaze 1 and 2.
• Stripperiffic: Her outfit seems like an altered versions of Oboro's.

Shigeru Washizu

The headmaster of Seishu Academy and uncle to Muneichi and Real. He is a secretly demon that forces both unsuspecting students and staff into sex slavery, or turn them into demon minions. He has some connection to Shiranui's disappearance.

• Big Bad: Serves as this for most of Taimanin Yukikaze 2. However, this is later subverted when it is revealed that he is actually just The Dragon.
• Beard of Evil
• Decoy Leader: Although he is the headmaster of the academy, he is only just a decoy for the true leader.
• Dean Bitterman: Unlike most example, this guy is genuinely evil.
• Dirty Old Man: He's 82-years old and tends to perv on women that are 3 times younger than him.
• Disc One Final Boss: He was defeated by the Taimanins near the end of TY2, only for heroes to find out that he was nothing more than a figurehead for the true leader of the demons controlling the academy.
• The Dragon: In actuality, he was this for Ryuji.
• Faux Affably Evil: He is able to fake a persona of a kindly grandfather, but it does little to hid his true evil nature.
• Fragile Speedster: He is very fast in his demon form. However, the second Shizuru wrapped her thorn whip around his neck, he was done for.
• Gem Heart: His demon form seems to have one.
• Humanoid Abomination: To put it bluntly, his true demon form is downright TERRIFYING!!
• Oddly Overtrained Security: The Taimanins realized how suspicious the academy really is after seeing that Shigeru's security includes Robot Spiders and Cyborg Security Guards.
• Off with His Head: How Shizuru ultimately kills him by decapitating him with her whip.
• Older Than They Look: Downplayed. He is stated to be 82-years old, but is surprising spry for a man his age. This is meant to foreshadow that he is no longer human.
• One-Winged-Angel: When he transforms into his bizarre demon form.
• Overly Long Tongue: Part of his demon form.
• Shapeshifter Weapon: While in his true demon form, he can protruded blades from any part of his body.
• You Will Be Spared: Although he has no problems killing people who would oppose him, he is willing to spare his opponents if they happen to pretty woman, so he can force them into a life a sex slavery.

Ryuji Kuroi

He was introduced as a third year student at Seishu Academy who is a part of the scholarship department. He is stated to be a delinquent and is apparently related to the school's headmaster, Shigeru Washizu. During the advent of Taimanin Yukikaze 2, Rinko (who was undercover at time) was assigned to be his maid, as students from the scholarship department are given a maid or a butler. It is later revealed that he is in fact an extremely powerful demon and the true main antagonist in the Yukikaze series.

• Arch Enemy: To Yukikaze and the Akiyama siblings, seeing as he is the mastermind behind everything that has happened in the Taimanin Yukikaze games.
• Barrier Warrior: He has able to create a near impregnable barrier during his fight against Yukikaze and Rinko in TY2. Although the Taimanin where able to bypass it thanks to Rinko's Space Master abilities.
• The Battle Didn't Count: The final battle of Taimanin Yukikaze 2 between him against Yukikaze and Rinko is treated as this. Despite Yukikaze and Rinko seemly destroying his One-Winged-Angel form, he just shows up again in human form unharmed. He then gives them a mocking congratulation before escaping with Shiranui at the end of the story.
• Big Bad: The hidden true main antagonist of Taimanin Yukikaze 2. He will likely be a more direct threat to the Taimanins in a future Yukikaze game.
• Bigger Bad: Of Taimanin Yukikaze 1. He also one for the Lilith-Soft game, Ochiru Hitozuma, due to his connection with Under Eden.
• Bishonen: As opposed to the usual Gonk villains in the Yukikaze series. But only in his human form.
• Evil vs Evil: His ultimate goal is to overthrow Edwin Black, and become the new king of all demons.
• The Heavy: He is the mastermind behind Shiranui's disappearance, Under Eden, and Seishuu Academy, making him responsible for all the advents that occurred in TY1 and TY2.
• Hot Guys Are Bastards: He is by far the most attractive villain (unless you you count the Brainwashed and Crazy Shiranui) introduced in the Yukikaze series and he is by far most the powerful and evilest of them all.
• Humanoid Abomination: His demon form.
• I Have You Now, My Pretty: Rinko was his primary target in TY2, but he also does this to Shiranui in Bonus Material.
• Jerkass: Even before it was revealed that he is a total monster (both literally and figuratively), the story established him as pompous bully the first time he is introduced.
• Karma Houdini: Although his organization has taken some blows due to the loss of many of its key members, Ryuji himself has yet to suffer any real punishment for his crimes, and is currently still at large. Only time will tell if karma will finally catch up to him.
• Long-Haired Pretty Boy/ White-Haired Pretty Boy: His human form.
• Man Behind the Man: It's revealed in TY2 that he has been the one controlling Yazaki, Real and Shigeru's actions. He was the one who commissioned Yazaki and Real to cause Shiranui's disappearance, and has kept the woman as his personal slave after they failed him.
• Nepotism: At first glance. Despite being a delinquent, Ryuji is part of the scholarship department, which was only reserved for student who had done exceptionally well on their academics. Many assume Ryuji got in because he was apparently related to the headmaster. In reality, he was Shigeru's boss.
• One-Winged-Angel: When he transforms into his true demon form, which is kind of looks like a hulking-winged Cthulhu.
• Properly Paranoid: Unlike Edwin Black, Ryuji tried to keep his existence hidden from the Taimanin as long as possible, by using Decoy Leaders, Yazaki, Real, and Shigeru.
• Red Eyes, Take Warning: Both his human and demon forms have red eyes.
• Suspiciously Similar Substitute: He's basically Yukikaze's equivalent of Edwin Black, just with all the Noble Demon traits removed.
• Walking Spoiler: It's really hard talking about this guy without revealing that he is the villain that Yukikaze has been looking for.

Hideo Inui

A butler who works at Seishu Academy. He would act Yukikaze's valet in Taimanin Yukikaze 2 if she infiltrates the school as a student. In reality, he is a dangerous demon who works for the Incubus King.

• Black Eyes of Crazy: In his demon form.
• The Brute: Acts as this among Ryuji's minions.
• The Butler Did It: He pretends to be a human butler as a part of his cover, but he is really a demon that is helping Ryuji in his plan to enslave Seishu Academy's students, either through demonification or sexual "training".
• Climax Boss: Serves as this to Tatsurou's character arc in TY2. Tatsurou finally being able to defeat a powerful demon by himself shows how far he has come in terms of fighting abilities, and gives him a much needed confidence boost. Plus points for killing his Love Interest's would-be rapist in the game's bad ending routes.
• Defeat Equals Explosion: His body explodes after Tatsurou forced one of his own fireballs down his throat. The explosion was able to knock Shigeru off balance and give Shizuru an opening to kill the other demon.
• Eyes Always Shut: In his human form. He only opens them when he is about to transform into his demon form.
• Fat Bastard: He is stated to have the physique of a sumo wrestler, and is an evil demon.

• Playing with Fire: He is able to create explosive fireballs in his demon form.
• Purple Is Powerful: He has purple skin in his demon form, and is very dangerous.

• Hellish Pupils
• Heroic Lineage: Her mother is a taimanin, but she clearly takes after her father.
• Human Mom, Nonhuman Dad: Like Kurenai, her parents are the vampire, Edwin Black, and the human taimanin, Kaede Shinganji.
• Mini-Dress of Power: Wears a white mini dress.
• Psychopathic Manchild: Her default behavior in Action Taimanin, which tones down her other more depraved attributes in favor of this.
• Red Eyes, Take Warning
• Sinister Scythe: Her weapon of choice.
• Token Evil Teammate: She can be recruited to help out Fuuma in Action Taimanin, but mostly because she likes him, she's still otherwise prone towards evil or petty acts, she just is working for the good guys because Fuuma insists.
• Spared by the Adaptation: She is killed by her sister at the end of Taimanin Kurenai, but is still alive in RPGX and Action Taimanin.
• The Starscream: For Tendo.
• Suspiciously Similar Substitute: A youthful pink-haired Cute Monster Girl that acts as The Dragon for a Big Bad. She seems to be one for Saya.

The Mysterious Man

The ringleader to group of demons responsible for the disappearances of many married ex-Taimanin. In Mama wa Taimanin it is revealed that he has been kidnapping former Taimanin to use them as part his Super Breeding Program. His plan is to turn the women he captured into mind broken Baby Factories due to their Superpowerful Genetics. He believe he can use these retired Taimanin as mean to create a new generation of powerful demons.

• The Bad Guys Win: One of the few Taimanin villains to ultimately succeed in his goals in his first game.
• Big Bad: Of Mama wa Taimanin.
• Boring but Practical: Rather than the big, ambitious plans of most Taimanin villains, the Mysterious Man targets past-their-prime and out-of-shape taimanin who've retired, and only confronts them directly when his schemes have eroded their will and it doesn't look like they've any intention of fighting back. This strategy works; he's able to amass a harem of sex-slaves and broodmares for super-powered demonic offspring without much risk of having more dangerous forces crashing in on him and get away scot free in both endings.
• The Chessmaster: The guy can give Edwin Black a run for his money in terms of cunning.
• Demoted to Extra: His role in poisoning Kenya was given to one of his henchman in manga adaptation, and many of his appearance at the beginning stages of the story were removed. He only shows up for a quick cameo at the end of the manga adaptation.
• Karma Houdini: Regardless of what ending the player gets in Mama wa Taimanin, he gets away with his crimes scot free.
• Lean and Mean: One of the lankier villains in the series, and very evil.
• Likes Older Women: Implied, as his MO is to kidnap retired married ex-Taimanin who are naturally older women. Although, part of it is pragmatism as former Taimanin, who have been out of practice for over a decade, are much easier to capture then active Taimanin who are in their prime.
• Offscreen Moment of Awesome: A villainous example. He was somehow able to defeat and capture Karin Sugita, the Great Detective among Taimanin, several months prior to the start of Mama wa Taimanin.
• Stalker with a Test Tube: He is basically his Kana and the other ex-Taimanin he has targeted, as his eventual goal is to force them to give birth to a new generation of super-powered demons.

An orc who is the head of a group of criminals headquartered in Shinminato-ku. After Asagi gives him and his gang a good hiding in ZERO’s Action Prologue, they become her underlings, with Byg working as her information dealer.

• Break the Haughty: Has a knack for being abused by Asagi and suffers several Mutilation Congas.
• Dirty Coward: See Villains Want Mercy.
• The Dog Bites Back: A villainous example. In ZERO’s Action Prologue, Asagi defeats Byg and his subordinates and forces them become her henchmen. However, after she gets a demon seed planted in her head, Byg tortures Asagi and has her raped consistently. Deconstructed as, Asagi makes him pay after she gets her demon seed removed.
• Dramatically Missing the Point: When Asagi asked Byg about how to remove Sakura’s demon seed, he mistakenly thought she was talking about the “training videos” he filmed of her. (Though, to be fair, she wasn’t being very specific when she asked him.)
• Even Evil Has Standards: Despite being the leader of a gang that rapes women to death, Byg was actually shocked by how cold-hearted Snake Lady is.

• Evil Sounds Deep: According to the narration, Byg has a deep voice.
• Laser-Guided Karma: See Mutilation Conga below.
• Lecherous Licking: One of Byg’s sprites has him doing this.
• Mutilation Conga:
  • At the beginning of ZERO, Byg tries to have Asagi dismembered and raped excessively until she died. However, Asagi kicks Byg so hard it causes him to rise up into the air. Subsequently, she kicks him in the groin and then the stomach. (Also, the latter snapped each and every one of his ribs at the same time.) She proceeds to kick him in the face and even slammed the tip of her shoe into his crotch, devastating one of his testicles.
  • In the visual novel’s good ending, Byg tried to have Asagi petrified and attempted to do the same to Sakura. (Although the latter was under Snake Lady’s orders.) Subsequently, Murasaki half-severs his arm and repeatedly hits him with the side of her blade. Asagi later delivers a stamp-kick to Byg’s face, which also breaks his nose. She also devastated his other testicle.
• Paper Tiger: Looks threatening but can’t beat a Taimanin (or at least Asagi) in a fair fight.
• Red Eyes, Take Warning: Double subverted. While he has red eyes and seems threatening, Asagi managed to defeat him and his gang with no effort on her part. However, after a demon seed is planted in her head, Byg uses this opportunity to do many atrocious things to Asagi.
• Smug Snake: Has a smug attitude.
• Villains Want Mercy: Starts sucking up to Asagi (who he tried to have dismembered and raped excessively till death) after she starts defeating his underlings. Also deconstructed because, as the narration states, this dilapidated his prestige as a leader.
  • Byg even does it again to Asagi in the visual novel’s Golden Ending. This despite the fact he tortured her, had her raped consistently, and forcibly impregnated.
• Would Hit a Girl/Would Hurt a Child: Tortures Asagi, who is a teenager in ZERO.
• You Need a Breath Mint:
  • Asagi: “——Your breath stinks. Could you shut up for a while?”

Big Gogo

Big Gogo, or just Gogo for short, is an ogre bondsman who fights in the Chaos Arena. Until facing Sakura, he boasted four straight wins and later became well-known for defeating female contestants.

• An Arm and a Leg: Sakura cuts off his arm.
• Bald of Evil: “Balding” in this case.
• Biggus Dickus: Well he is a giant monster in a Hentai.
• The Brute: A classic Dumb Muscle variation.
• Character Tics: Begins twitching his eye when frustrated.
• Dumb Muscle: He's a huge mound of muscle, but isn't too bright.
• Establishing Character Moment: Kills a female contestant and announces that he violated and killed her. Also, according to the narration, her head was ripped off to boot.
• Huge Guy, Tiny Girl: The Huge Guy to Sakura's Tiny Girl.
• Hypocrite: Had the gall to call Sakura out for being “cruuuel [sic]” when she cut off his arm. This is coming from someone who viciously tortured, raped, and slayed numerous woman. 
• Laser-Guided Karma: Played with. While the event of having his arm cut off was obviously painful, it did not stop Big Gogo from continuing his winning streak and earning a name for himself.
• Lightning Bruiser: Surprisingly agile and is certainly strong.
• Mutilation Conga: Sakura cuts off his arm and delivers a roundhouse kick to his face. This causes him to fall to the ground and loses consciousness.
• Red Eyes, Take Warning: Has red eyes.
• Villainous Breakdown: Freaks out when Sakura cuts off his arm.
• Would Hit a Girl: Forget hit; Gogo has tortured and slew numerous women.
• Would Hurt a Child: Has no qualms toward harming Sakura, who is a teenager in ZERO.

Toyo Momochi 

Toyo was a former Taimanin of the Igawa clan turned traitor who actually mentored Asagi in her younger days in melee combat. His exact Ninja Art is unknown. He's an Asian supremacist terrorist in league with NOMAD (mostly because they share the same foes). His main goal seem to be that he wants to humiliate the Chinese Federation and United Federal States and break their influence over Japan and other Asian countries. He also has ambitions of being their new overlord of Asia. Toyo is clad in all-black ninja armor with spikes on it. He wields steel chains and a long sword named "Abara".

• Actually a Doombot: The guy has a really annoying habit of sending demonic body doubles to fight in his place, such as the boss in Chapter 4.
• An Arm and a Leg: His arms can be destroyed during his final boss fight in his One-Winged Angel form. Oddly enough, after his corpse return back to its human form, his arms are intact.
• Back From the Dead: Although he is killed by the Taimanin Task Force in Chapter 5 of Action Taimanin, he is eventually resurrected because of an unique variant of demonic zombie mutation that Edwin Black provided him.
• Big Bad: For the main story campaign of Action Taimanin.
• Body Horror: As Toyo Momochi Creature, his armor ended up melding to his body.
• Cool Sword: His long sword "Abara".
• Darth Vader Clone: Let's see here, dark armor, red sword (blue in-game), deep voice, a traitor to an order of supernatural people, and a connection to the main protagonist's past. The fact that he was a part of the Igawa clan implies that he might be related to Asagi and Sakura. In short, he most definitely qualify as this.
• Disc One Final Boss: Despite being the Big Bad for Action Taimanin's initial story campaign, later expansion made to the game and its story mode effective make him this for Action. Possible subverted, when he is eventually resurrected.
• Evil Former Friend: To Asagi, her former swordsmanship instructor. All the more impressive given he was, at the time, just a normal man. While sometimes his Evil Plan involves trying to build a Japan where the strong rule over the weak, other times he's trying to collapse the government so she'll install herself as a military dictator over the politicians he despises to restore order..
• Evil Mentor: He was one of Asagi's mentors before he went rogue.
• Evil Virtues: Downplayed. Momochi tend views himself as the "hero" of the story. At least he has moral high ground among most of the villains on this list for not being a serial rapist, as far as we know. It helps that he is a Big Bad in a non-Hentai game. But makes no mistakes, the guy is a crazy terrorist who is willing to turn innocent people into demons and/or zombies. Eventually deconstructed in a later chapter, where Fuuma points out how insane and self-contradictory his goals have become after engaging in self-abuse and putting all that demonic power inside himself.
• Expy: In terms of appearance and fighting style, he is a pretty blatant one to Ryu Hayabusa.
• The Faceless: We don't actually get to see what he looks like without his mask. Although Asagi apparently knows what his true face looks like.
• Final Boss: To Action Taimanin's story campaign, however later expansion made to the game's story mode ended up effective making him a Disc One Final Boss.
• Foil: To Oboro, Asagi other mentor who betrayed the Taimanin and became a crazed super-villain. The difference between the two is that Oboro is a Card-Carrying Villain who lives for the sole purpose of making Asagi's life a living hell, while Momochi sees himself as a "hero" who clearly has greater ambitions than pretty revenge. There also the fact Oboro Koukawa never actually betrayed the Taimanin and it was her evil clone that went on to becomes Asagi's Arch Enemy, while Momochi himself was an actual traitor. There also the fact that both of them has a bad habit of not staying dead.
• Heel Face Turn: After his own daughter sides with the Task Force, he nearly dies from all the demonic power he's imbibed while most of his followers do perish outright, and he realizes that not only was his need to gain powers from dark sources unnecessary but played into the hands of the demons he despises, Momochi helps Asagi fight off Astaroth and retreats into hiding, where his daughter tells the group he's trying to recuperate from his ruined body but hopes to support them going forward.
• Master of Illusion: As Toyo Momochi Creature, he can create illusion of human form that serves as his Mooks during the boss fight.
• No-Nonsense Nemesis: Downplayed, as the guy still need to do his villain monologues. That said, Momochi prefers to go for the kill, whereas most of the other villains prefer to capture their opponents alive in order to torture and break them to satisfy their own sadistic needs but risking the chance of the heroes eventually escaping.
• One-Winged Angel: During his final boss battle where he shoots himself up full of the Creeping Death Virus, turning him into some massive 10 meters tall gigas-like demon referred to as Toyo Momochi Creature. His new monstrous form looks like his human form turn feral with a glowing blue skull and one of his hands has a glowing blue spot on the palm, the other is a Wolverine Claws styled appendage. Curiously, later added chapter to Action's story mode revealed that his body returned back to its human form after his apparent death, which has a separate form that's more like a villainous equivalent of Heroic RROD.
• Red Eyes, Take Warning: Has red eyes and was regarded as one of the strongest Taimanin back in his day, to the point that Asagi immediately surmised that she was not fighting the real Momochi the first time he was defeated, as the real Momochi would not have gone down so easily.
• Sanity Slippage: It's easy to misunderstand thanks to his self-confident and self-assured presentation, but Momochi is actually quite mad and only getting crazier as the story goes on. Fuuma eventually realizes he doesn't even have a consistent plan lined up, and many of his goals are contradictory and shifting, thanks to the demonic power inside him eroding his sanity.
• Scarf of Asskicking: Wears a ragged blue one.
• Self-Duplication: Seems to be his ninja art, as he does make clones of himself during his final boss battle and even in his One-Winged Angel form. However, it is possible that those are just his body doubles. In case of Toyo Momochi Creature, his character bio clears up that the monster is only creating illusions of his human form, and it's later confirmed that he has no Ninja Art and the others are just body doubles.
• Shadow Archetype: Ultimately, to Kotarou Fuuma himself, a fellow Taimanin born unable to use a ninja art. But where Kotarou learned to lean into his strengths, taking pride in his skill as a tactician and coordinator while pushing himself to try to keep up with his superhuman teammates, Momochi gave in to his own self-loathing, ultimately making dangerous deals with demonic creatures and engaging in self-abuse and transhumanism in an effort to gain powers, eroding his sanity and humanity and nearly costing him his life.
• Spell My Name with an "S": Depending on the translator, his name could be spelled as "Touyou Momochi" or in the case of the official English translation of Action, "Toyo Momochi".
• Spikes of Villainy: To give him that edgy villain look.
• Your Terrorists Are Our Freedom Fighters: Well he and his followers certainly believe that they are "heroes" who are pushing foreign powers out of their land, at the cost of killing innocent people and turn civilians into monstrous demons. Naturally, none of the actual heroes believes his rhetoric for one second.

Ou-chan 

• Giant Mook: When introduced, he is almost twice as tall as Oboro and other orcs.
• A Worldwide Punomenon: Oboro refers to him as a "big" fan of Asagi, referring to him being a literal giant.
• Your Size May Vary: He is a giant, but how giant usually varies. When he is introduced he is almost twice as tall as Oboro, but when he fucks Asagi the difference does not seem to be that great.

Astaroth

Self-titled "Queen of the Inferno" and other similar titles, she rules over the fiery, magma-and-fire filled Burning Plains of the demon realm. One of the "royal demons", standing in the same leagues as Edwin Black. Unlike him, however, she has no real desire to rule over humans and is instead simply content to enjoy her power.

• Interplay Of Sex And Violence: She's finds them equally entertaining, and is amazing at both.
• It Amused Me: Being as she's not interested in ruling over the human world and has grown bored of the Demon Realm after ruling part of it for so long, many of her actions boil down to "she was bored and wanted some fun". The playable version of her in Action is, according to her bio, only doing so "on a whim."
• Person Of Mass Destruction: She does not have the same finesse as Black, but her destructive powers are massive, as she is easily able to torch entire islands when provoked.
• Playing With Fire: If her title didn't clue you in, the fireballs she pelts your characters with durign her boss fight will show you why she has it.
