Welcome to the Garden of Eden

STARLESS 21st Century Nymphomaniacs, known in English as STARLESS Nyphomaniacs' Paradise, is an H-game by Sei Shoujo, the same artist and writer of Discipline: The Record Of A Crusade and Bible Black. Like most of the games which he has created, it features exquisite artistic detail and every twisted sex fetish you can possibly name shoved into an eroge plot. It was released in Japanese in 2011, and in an English language adaptation in 2015.

The protagonist is Sawatari Yukito, a guy who just wanted to earn some money over the summer, and unwittingly took a job offer to be a handyman for the Big Fancy House of the Mamiya family out in the country, since they were offering quite a bit for the job.

Soon after he arrives, he quickly finds out the job title is In Name Only. In fact, the residents of the mansion are kinky, twisted aristocrats who engage in perverse sex play of every sort, and he's now forced to join the maids of the manor in pleasing their every decadent whim.

That is, unless he can escape.....

In 2019, Great Deceiver, a sequel featuring Mamiya Marie as a returning villain, was released in Japanese. No English adaptation has been announced as of the end of 2019.

Tropes used in STARLESS include:
  • Absolute Cleavage: Marie, Sachie, Yuuna, and Mikako.
  • Affably Evil: Marie and Marika are polite and charismatic, even if what they do is pretty nasty and wicked, as noted by Sawatari.
  • Alpha Bitch: Marisa makes even Leona looks tame by a standard.
  • An Aesop: Several.
    • If something seems too good to be true, then it is usually best to assume that it is.
    • Do not accept a random job with an unreasonable payout unless you know all the details regarding the employer.
    • Sometimes, it is best to just walk away from bad people instead of going up against them.
    • Gambling will never reward you.
    • Not all the evil in the world will face justice.
    • Virginity and sex aren't something that decides how good or evil you are, it's what you think and do that matter.
  • And Now You Must Marry Me: In Bizarre Marriage ending, Yukito is forced to marry and stay with Marika in the mansion forever in exchange for not paying for the broken vase. Clearly, he is unhappy with it.
  • Aristocrats Are Evil: And unbelievably perverted.
  • Baby Ever After: Yukito with Mikako, post Time Skip in the "A New Family" Ending and with Yuuna post Time Skip in the Golden Ending.
  • Bittersweet Ending: Even in the only two good endings: The Mamiya are still free to trap unwitting people that fall into their web like what Yukito and the rest went through.
    • Yukito, Yuuna, and Sachie manage to leave the mansion alive with the remaining 1 million. Yuuna reunites with her parents and recently-cured younger brother. Yukito and Yuuna begin a relationship together and they eventually marry. However, Mikako and Makoto were sold into sexual slavery..
    • Yukito spends his money to save Mikako and Makoto from being sold into sexual slavery (in essence, buys them) and is forced into marriage with Mikako and all three are sent to a new house to live their new lives together as a family..
  • But Thou Must!: The majority of Yukito's choices have no influence on the events that occur throughout the game (except those that decide the final outcome), and he must follow the Mamiya's every command.
  • But You Screw One Goat!: Bestiality is heavily implied to be something the Mamiya family is not above engaging in and horses, dogs, and even pigs are shown in incredibly graphic sex scenes with some of the female characters in some of the bad endings.
  • Book Dumb: Marisa, who doesn't do well in school. Becomes a funny moment when she lost her bet and had to finish her homework by herself after Yukito and Yuuna won the final lesson.
  • Captain Ersatz: Kimishima's overall design pretty much screams Chun-Li.
  • Covert Pervert: Marie believes Yuuna is one, and blames that on her next to non-existent sexual experience.
  • Death by SexMarie killed Mikako's husband during the party while having sex with him. Averted by the characters in most of the bad endings which they instead suffer Fate Worse Than Death.
  • Excuse Plot: The game plot is very shallow, though certain choices can lead to different endings.
  • Face Heel Turn: In the Flowers of Evil ending, Sawatari sells Sachie out and become Marie's butler who tortured the newcomers in the Mamiya's place. Implied in the OVAs' ending, in which Yukito and Yuuna succumb to lust and desire, and continue to work at the estate as they lure other unsuspecting people in there.
  • Fantasy Contraception: Averted. The characters take contraception drugs developed by the Mamiya Group through the meals or using condoms to prevent unwanted pregnancy. Marisa does mention that the drugs do have limits in effectiveness, though.
  • Failure Is the Only Option: You cannot escape from the Mamiyas early in the story because of the tracking device inside the bracelet (which also contains an explosive). Doing so will lead you to the first bad ending.
  • First-Name Basis: Practically everyone in the game except Yukito and Yuuna.
  • Heads I Win, Tails You Lose: The overall plan by Marie: She gains lots of money by whoring the servants to her guests at the party, making the 4 millions she paid to each of them in the contracts pretty cheap, and that's not counting her attempt to trap them in slavery or selling organs of those she killed.
    • The pool game with Marika will always lead to bad outcomes. Either you win and she rigs the car to get you into an accident, or lose and she basically forces you to marry her. The only way to truly win is to not play against her.
  • Fiction 500: The Mamiya are extremely rich, powerful, and influental to the point that they have nothing to do but to engage in their lewd desires to pass the time.
  • Futanari - One of the daughters of the Mamiya family is a true hermaphrodite, having both male and female organs and are both fully functional, as you will find out in one of the endings. One of the endings also features the son of one of the maids being turned into a transsexual.
  • Good Girls Avoid Abortion: Marie mentions that, if Yuuna gets pregnant, she would do an abortion in a way which the mother wouldn't never know she was pregnant in first place. Yukito is understandably frightened and horrified, specially since it could be his child.
  • Guide Dang It - With the game's numerous meaningless choices, looking up the guide is the only way to know how to get to the ending you want.
    • Special mention goes toward the path to the Golden Ending in which there are several requirements to meet: On the night of Day 9, Yukito must peek at Marie's deal regarding the orphanage she is currently financing in order to shift her attention from Yuuna to him. Next, Yukito must lend Sachie 3 million of his salary to her (which she will lose in her betting with Marika), and refuse to engage in the pool game with Marika, as the former will cause Sachie to feel indebted to you while the latter will allow you to avoid the car trap.
  • Golden Ending - The New World ending, which is literally represented by a gold key.
  • Groin Attack - In the very worst ending, Yukito's penis is sliced off with a guillotine.
  • Idiot Ball - 4 million yen for a two weeks job as a handyman doesn't raise any suspicion from Sawatari at all until it's too late.
  • Karma Houdini: In contrast to Sei Shoujo's previous and following works, the Mamiya never face justice for all their actions of putting many people through hell and alike, not even in the only good ending.
  • Kick the Dog: All the bad endings but especially, the Endless Nightmare
  • Lighter and Softer: The hentai anime adaptation tones down quite a bit of the most depraved parts of the game such as the bestiality, scat, and guro, while keeping most of the less graphic scenes intact, though several details were changed. 
  • Love Potion: Self-developed aphrodisiacs are spiked in every meal at the mansion. Marie also sells them to the guests at her party.
  • Madonna-Whore Complex: Marie believes that Yukito's silence while watching Yuuna masturbate is the product of having this kind of conception shattered. Yukito is actually trying to hide his arousal at it, and reminds himself that that was Marie spiking Yuuna's drink with aphrodisiacs which led to this lewd, exhibitionist act.
  • Meaningful Name: Switches the kanji for "ma (間)" in Mamiya with "魔" and it now means "Demon Palace", a fitting name for the (demon) aristocrats. The last kanjis in the Mamiya women's names also refer to their character/personality: Marie is painting (refers to her beauty), Marika is flower (again, refers to her beauty and also a kanji used for "flamboyant"), Marisa is sand (refers to her rough Alpha Bitch status).
  • Mercy Kill: In the bad ending EscapeAfter telling Yukito that his organs will be sold, Marie offers to give Yukito a painless death before they take his organs through asphyxiation (she did consider injection, but the poison will damage organ quality).
  • Multiple Endings: Two good ends, at least three endings that are terrible in their own ways but not nearly as bad as they could be, and several incredibly Nightmare and Nausea fuel filled Bad Endings. Described below from the worst to the best.
    • The Worst End: Yukito and Sachie are caught and tortured by the Mamiya. Yukito is given Groin Attack as described above and becomes Marie's toilet while Sachie is forced to have sex with a horse.
    • Escape: Yukito and Yuuna try to escape the mansion but are caught and punished by the Mamiyas. Yuuna is sold to a customer who likes bestiality and eventually is driven insane, while Yukito is killed and his organs are sold.
    • The Endless Nightmare: Yukito and Yuuna are tricked by the Mamiya who rigged the car which Yukito won from Marika, captured, and turned into human livestock.
    • A New Master: Yukito falls for Marie's vase trap and is sold to Kimishima, who is known to overwork her male servants (which killed them).
    • The Black Video Letter: Yukito is allowed to leave the mansion without any money due to being stolen by Sachie but Yuuna falls for the vase trap and is sold to Marie's customers.
    • The Soiled Bride: Similar to the above but Yukito tries to save Yuuna by betting for her in the auction. Marie does allow her to leave with Yukito after all the customers have their way with Yuuna (for several years).
    • The Flower of Evil: Yukito betrays Sachie to save himself when Marie finds them out and is convinced with money to join the Mamiya's side, becoming their right hand butler while Yuuna and Sachie suffer.
    • Bizarre Marriage: Sachie tries to stop Yukito from falling for Marie's vase trap, but is stopped by Marika, so Yukito is forced to marry Marika as payment who cooks up a lot of inedible foods for him.
    • A New Family: Yukito uses his money to pay for Mikako's debt, but by doing so, Marie declares that he has "bought" Mikako therefore Mikako must marry Yukito to accept the money. Marie "fixes" the "problem" of Mikako being already married by killing Mikako's current husband (Nonohara Hiroyuki). Marie allows Yukito, Mikako, and Makoto to leave the mansion and move in together and Mikako ends up being much happier with Yukito as her husband and his (or Makoto's) unborn child; Mikako, while having sex with Yukito, even states that "It's [Yukiko's penis] so young and virile! My last husband was nothing in comparison!".
    • A New World: Sachie leaves the mansion but not before saving Yukito from Marie's vase trap. Yukito and Yuuna walk away from the mansion safely and alive with the rest of $1 million and they eventually marry with blessing from Yuuna's parents. Yuuna becomes pregnant with Yukito's child.
  • Musical Theme Naming: The game name is derived from a British progressive rock song.
  • The Precious Precious Car: Marika owns several expensive sports cars she kept in the house's garage. She isn't allowed to drive due to Marie confiscating Marika's license after a racing accident which she caused. In fact,one of the sports cars, which Yukito can win from her, will always lead to one of the bad endings no matter what.
  • Parental Incest:
    • Makoto openly admits early in the game that he masturbates to the footage which he shoots of his mom having sex.
    • Despite their perverseness, this is averted in the case of the Mamiyas. In fact, Marie says to Yukito that she actually never breastfed Kyouchi as a baby, and that may be the reason why her son lusts after Makoto's mom, Mikako, to compensate for this lack of maternal love.
    • There is a sex scene with the son of one of the maids and his mother.
    • Yukito discusses the trope, believing that maybe he would have engaged into this if his mother was as good looking as Marie is.
  • Please Put Some Clothes On: Yukito asks this to Marisa, who is dressed in only her underwear, at the start of the second day. Of course, the power dynamics are heavily in her favor, so she only scolds him for even asking that.
  • Potty Failure: Marie has problem with constipation which she often brings up and gets Yukito to help her on one occasion. Given what she indulges in, it's not surprising. In the other example, Marisa drugged the milk that Yuuna drank for breakfast and had her use Yukito as a toilet (literally).
  • Squick - The game itself is filled with practically every perversion Sei Shoujo could fit into the plot. Invoked in-universe by the protagonist, who is pretty disgusted with most of the Mamiya family's perversions. Becomes pure Nightmare Fuel for him in the ending with Marie.
  • Title Drop: An inversion. In the only good ending: As Yukito and Yuuna walk down the mountain toward the town, they finally see the sky full of stars, signifying that their misery is finally over and their happiness begins now.
  • Throw the Dog a Bone: Marika allows Yukito to look after her sport cars after knowing that they share the same interest. 
  • Tsundere: Marisa seems to secretly desire Yukito and feels envy when he haves sex with her sister, but keeps treating him horribly because she feels he is beneath her.
  • Unprovoked Pervert Payback: Because Marisa is a jerkass, that is why. She calls Yukito a pervert, but the truth is that she simply sees him as beneath her.
  • Up to Eleven: Invoked. Some of Sei Shoujo's most beautiful artwork and some of the most depraved perversions can be found in this game.
  • World of Buxom: It's a game created by Sei Shoujo after all.
