Future Diary/YMMV

• Alas, Poor Scrappy: Although most of the fandom hated him, Yuki's father has his death treated with sympathy.
• Alas, Poor Villain: Yuno gets one of these when she kills herself to allow Yukki to be God, although Yuno is generally considered a very dark Anti-Heroine rather than a villain.
  • The anime seems to do this for Tsubaki as when she's killed in the manga, she's angry about how the ball she lost came back to her. The anime counterpart however has a different set of tears as she asks calmly to herself why the ball came back and then adding that it was too late to stop her so why appear now?
• Alternative Character Interpretation: Is Yuno truly a cold, nihilistic sociopath with no regard for the lives of anyone but Yuki, or just a deeply insecure, paranoid girl so scared of losing the one she loves that she sees Murdering the Hypotenuse as the only option, but doesn't actually enjoy killing at all? There are certainly a few scenes that suggest the latter, making you wonder if she really means everything she says. Either way, her mental state is undeniably fragile.
  • Akise. There are some scenes that suggest he's not the Nice Guy he presents himself to be. Despite appearing to be more heroic than the other characters, Akise does some morally dissonant things that would arguably make him, while more subtle, no different from the rest of the crazy characters in the series.
• Base Breaker: You either think Yuno is epic Yandere Fetish Fuel or you get nightmares about her. Or that Yuno is just a psycho insane unlikeable bitch. Or a psycho insane lovable bitch. Take your pick. However, according to myanimelist.net, Yuno is the most popular character by more than double the votes, so ultimately, the people who love her far outweigh the people who hate her (they don't call her the Queen of Yandere for nothing).
  • Yukiteru is probably an even bigger one. Some fans like and applaud him for the levels in badass he takes over the series, while others just can't forgive him for his wimpyness in earlier episodes. Then, there are those who consider him a very relatable and sympathetic character who reacts realistically to the situation he's been pulled into, while also praising him for his Character Development.
  • Akise is either a Badass Adorable Guile Hero or a Depraved Homosexual depending on which side of the fandom you talk to.
• Crazy Awesome: Yuno, in spades. Also, Yomotsu Hirasaka, the 12th user, who is over the top in every way, just to be a "hero of justice".
• Creepy Sexy: Yuno. This picture outta just about cover it.
• Crosses the Line Twice: Takao Hiyama appears in a flashback in the middle of one chapter...to take a spear in the back courtesy of Yuno. Him being an Asshole Victim is probably what makes it so funny in the first place.
  • So many of the things Yuno does can qualify as this.
• Crowning Music of Awesome: The anime's opening song is insane, frantic, creepy, and very catchy.
  • Dead END is also very catchy (Warning, the engrish lyrics spoiled the premise of the series.)
  • Let's not forget the ending themes.
• Draco in Leather Pants: Yuno gets her negative qualities toned down in the fandom because several guys (and girls) are attracted to her.
  • To an extent, Minene Uryuu.
• Die for Our Ship: Both Yuno and Akise are victims of this.
  • The Yuno/Yuki fans hate Akise's guts for being in love with Yuki. It's not helped that he was killed the minute he confessed his feelings.
  • The forums will go to extreme lengths to express their hate for Akise going as far as to call him a "fag that deserved what he got". Seriously...Fan Dumb...
  • Akise/Yuki fans hate Yuno for the things she does to Yuki. Not helped by the fact that she killed Akise after he kissed Yuki.
  • Ultimately, however, this Ship-to-Ship Combat shows up in relatively few fandom circles.
• Ensemble Darkhorse: Akise, and to a lesser degree Minene, 7th, and 12th.
  • Akise has his fair share of haters though, making him more of a Base Breaker like Yuno. Minene and 12th (and possibly 7th) are actually straighter examples than he is.
• Evil Is Sexy: Minene and Yuno.
• Fan Nickname: Minene Uryu the Cosplay Bomber.
• Fashion Victim Villain: The 12th has what could be the most hideous costume in the history of mankind... Okay, so that's a mild exaggeration. Partially justified by the fact that he's blind as a bat.
• Hilarious in Hindsight: One quote on Norio Wakamoto is God exists and he is japanese. Guess who voices Deus in the anime adaption?
• Ho Yay: Has its own page.
• HSQ: The second episode of the anime has an extremely high one.
• Just Here for Godzilla: Some people read the manga or watched the anime only because it has a Creepy Sexy Yandere character in it.
• Magnificent Bastard: A TON of characters. As of the most recent chapters Yuno Gasai is starting to look like the biggest one of all.
  • By the end, she DEFINITELY is, seeing as she pretty much ends up with exactly what she wanted - the heart of her beloved Yukkiteru.
  • Other qualifiers are Keigo Kurusu, Tsubaki Kasugano, Minene Uryu, Aru Akise, and Murmur.
• Memetic Mutation: The face that Yuno made at the end of the first episode is already turning into one. Known on Pixiv as 恍惚のヤンデレポーズ [1] (lit. "ecstatic Yandere pose") and on Danbooru as yandere trance.
  • GONNA PROTECT THE SHIT OUT OF YOU
• Moe: Yuno manages to be both this and Nightmare Fuel, often at the exact same time.
• Moral Event Horizon:
  • Tsubaki crosses this when she orders her followers to strip off Yuno's clothing... and to gang-rape her, all so she could lure Yukki out of his hiding place.
  • Mur Mur crosses this when she undoes the positive future in Paradox by deliberately erases everyone's memories and goes back in time to make sure that the 2nd is still alive and kills them all. She also uses the wounded Yuki to prevent Akise from stopping her plans. And she did this to save herself from God's wrath.
• Narm:
  • Read the first chapters and see such dramatic scenes as Yukiteru's reactions and Esuno's mad Photoshop skills.
  • The English covers. "Every text could be your last."
  • Marco's ridiculous pompadour
• Never Live It Down: As mentioned above, Yukiteru starts off as a crying wimp, and some find it hard to forgive him for that. What this fails to take into account, however, is that the way he acts is exactly how a withdrawn 14-year-old boy would in real life if they found themselves in his situation. It's a small wonder Yuki doesn't complain more, especially seeing as Yuno is the only one he can trust. And in episode 18 and the ones that follow, he more or less completely makes up for it.
• Paranoia Fuel
• Periphery Demographic: There are a surprising number of females who watch the series just for Yuno.
• Rescued From the Scrappy Heap: Yukiteru when he finally Grew a Spine.
• Ron the Death Eater: While Yuno gets more of the Draco in Leather Pants treatment, there are some who make her out to be an utter monster no redeeming qualities and unfairly blame her for things she had no control over, all with No Sympathy for her tragic backstory. For example, some claim she crossed the Moral Event Horizon when she left a group of students to die in explosions for giving up Yuki to Minene, while completely ignoring the fact that Minene was the one who placed those bombs in the first place and so should get at least some of the blame. And in Yuno's defence, it's not like she had a lot of options.
• Squick: A few chapters after Yuki and Yuno's Happy End, Yuki says something along the lines of "I went here two years ago, when I was in elementary school."
• Superlative Dubbing: It had a rough start, but it gets much better; the Woolseyism improves as the series goes on.
  • Even those who don't like the dub version can't help but agree that Kent Williams as Deus Ex Machina is GLORIOUS.
  • Notably, the English dub replaces all of Yuno's constant exclamations of Yuki's name with cutesy pet names, which is simultaneously unsettling and absolutely adorable.
• Ugly Cute: The 8th diary holder, Kamado Ueshita, is considered by some people to be cute despite her odd shape.
• Unfortunate Implications:
  • Akise, Hinata and Mao have the most Ho Yay/Les Yay moments with their potential love interests. All of them are killed but special mention goes to Akise who was killed in a gruesome fashion.
  • Then again, this is a world where Anyone Can Die, and they weren't exactly killed because they were gay. They were killed because they got in the way. Well, apart from Akise, but he kissed Yuki in front of Yuno. Man or woman, that may as well be shouting out "Kill me, kill me Yuno. Please kill me" It helps his case he was trying to get her angry, but that worked a little too well.
• What Do You Mean It's for Kids?: Can you believe Mirai Nikki was serialised in a shounen (for 10-18-year-old boys) magazine? To play this trope even straighter, Mirai Nikki is off limits to anyone below 18 on Mangafox, a scanlation website, which labels it as seinen (for adult males over 18).
• What Measure Is a Non-Badass?: Yukiteru was a victim of this early on.
• The Woobie: Early Yuki varied between this and scrappydom. But really, try being a shy and introverted young boy shoved into a duel to the death with a bunch of psychopaths. Oh yeah, and the only ally you can truly trust is the crazed Yandere, whose main goal is marriage and/or sex with you. He seems to have recently graduated to Woobie, Destroyer of Worlds.
• Woobie, Destroyer of Worlds: Yuno Gasai. By the time 3rd world rolls around, people will want to give her a big hug. Not that she'd accept one from anybody but Yuki.
  • Tsubaki is revealed to be one of these when her tragic past is revealed.
• X Meets Y: Battle Royale meets Death Note.
