History Characters / FutureDiaryDiaryHolders

* BastardlySpeech: His debut scene is one of these. He feigns concern for 8th's orphans and asks the city council to shut the orphanage down due to "terrorist attacks" from Yuki and Yuno. In actuality it was the orphans (including Marco and Ai) who attacked first, and he just wants to shut the orphanage down to make it easier to force 8th out into the open.

* NotGoodWithPeople: He cares a lot more for his dogs than other humans, including his own family.

* Really700YearsOld: He spends 10,000 years doing nothing after becoming God, but he still looks quite youn afterwards.

* BecomingTheMask: At one point he declares that Yuno is his girlfriend to calm her down in order to stop her from killing Hinata. At that time his declaration was insincere, but by the end he comes to genuinely love her.

* NinetiesAntiHero: She's a badass DarkActionGirl with misanthropic tendencies, morally ambiguous, violent, and a MsFanservice (her later outfit even [[BareYourMidriff bares her midriff]]).

* BareYourMidriff: Her usual outfit exposes her belly.

* DidntSeeThatComing: The vault was only able to be opened by himself and the Gasais. Yuno's parents were dead, and Yuno herself was determined to be the third corpse in her house. This meant that the girl claiming to be Yuno had to be an imposter, as far as John knew. So hiding in the vault should be a foolproof plan, right? Not when you're dealing with a time-traveling goddess like the first-world Yuno.

* DidYouJustScamCthulhu: According to Deus, John promised that he would use the Future Diaries for the good of humanity if he agreed to help him create them. While John may believe he is indeed working towards a greater purpose, Deus doesn't seem too thrilled when he learns 11th's true intentions. Also, John clearly used his position as co-creator of the diaries to his advantage by making his diary one of the best. In the 3rd world, Deus seems to realize that John is trying to manipulate him, so he turns down all of the Mayor's proposals for a new game.

** The Twelfth's diary (Justice) reflects his justice seeking outlook.

** Marco's first name comes from "Mars", the Roman god of war, and his last name's kanji is read as "battlefield", sealing the comparison. Ai's name indirectly references Venus, as her first name means "love" while her last name contains the kanji for "beauty" and "god", all strongly pointing to Venus as a reference. If that wasn't enough, Mars and Venus were also well known in the myths for their love affair. Their Child Diaries take the comparisons one step further, with Marco's being a diary that predicts his opponent's next fighting move, so he can counter it, and Ai's making predictions about all the men that she wants to flirt with in the future.

* SmugSnake: Most of the Diary Holders are confident at their skills, but the end they are defeated nonetheless.

** Kamado's Propagation Diary allows her to mass produce Child Diaries. However, this means she has no diary of her own, meaning that she has to rely on others to fight for her. Also, the Child Diaries require an internet connection to work, making them vulnerable to signal jamming.

A timid boy who views life as though he were a casual bystander. His "Indiscriminate Diary" records future observations about everything and everyone around him, although it usually doesn't record any information about himself except for his DEAD END. At first he's unwilling to participate in the Diary game, but Deus still considers him the favorite to win. He has an...interesting relationship with Yuno.

* BadassAndChildDuo: Strikes this with Minene especially during the FinalBattle.

* BadassUnintentional: Taking out Hiyama was only an act of self defense, but by becoming the first diary holder to kill another diary holder, Deus called him the prime candidate to win the Survival Game. This made the all the rest of the diary holders set their sights on him.

* BewareTheNiceOnes: Yuki is a nice and shy boy, but can fight back in self defense and later he starts to go quite crazy.

* ClassicalAntiHero: For all the power that his diary gives him, he is cowardly, lonely and awkward dork who's very reluctant to act. Though he cares for others and is willing to be brave he feels the need to step up.

* {{Determinator}}: Shows shades of this later. In the final battle he declares he will save Yuno no matter what.

* ExtremeDoormat: Initially he views himself as a spectator from the sidelines and doesn't do much to fight back. This manifests in the power of his Diary, which see only the future of the world around him.
* FailureHero: Yuki is a spineless weakling who's pretty ineffectual and naive in the Survival Game and he relies on Yuno to fight his battles. Most of his goals ends up becoming AllForNothing but he's still able to save 3rd-world Yuno.

* FriendlessBackground: Due to Yuki's introversion, he never had any friends though he becomes so lonely that he starts becoming desperate to have friends and while he does succeed initally, Yuno's possessiveness gets in the way and she manipulates Yuki into turning against just so she can be Yuki's only ally.

** Yuki goes into a severe depression after his mother is killed by his father.

* HiddenDepths: While Yuki is physically unimpressive, he has surprisingly quick reflexes which often comes in handy.

* LoserSonOfLoserDad: Only Kurou is far more pathetic and cowardly than Yuki will ever be because while Yuki is a wimp, he's willing to anything for Yuno and his family, while his own father abandons him to die with Yuno in a building that's breaking down and kills his wife just to avoid taking responsibility for his actions.

* NervousWreck: Prone to freak outs, especially with Yuno's insanity and impulsiveness bringing more harm than good.
* NiceGuy: Yuki is very sensitive, gentle and compassionate for a guy in a game of death and often times, he tries to be the merciful hero until he's forced to get his hands dirty.

* NoSocialSkills: He's a pretty awkward teen due to being social recluse and he starts off not having any friends.

* OnlySaneMan: Out of all the diary holders, he appears to be the most sane and rational. However as the series goes on, he slowly begins to slip.

* SanitySlippage: Initially he was an emotional, neurotic and passive introvert, but after witnessing so many people die and losing his parents, Yuki loses his sanity and becomes a murderous extremist in order become a god and he even kills his friends for getting in his way.

* SpannerInTheWorks: He hijacks the entire future of the third Survival game when he follows Yuno to the 3rd-world, since his data entries in the second game show up in 3rd-world's John Balks's diary and warn him of the incoming disasters. It changes every diary holder's future and gives them happy endings.

* ThisLoserIsYou: Yuki is a fearful and fragile teenage boy with quite a few social phobias who hates getting involved in conflicts and rather than facing his problems, he prefers to isolate himself and drown out the world with his cellphone and imaginary friends.

* WellIntentionedExtremist: Later, Yuki does really extreme things like tricking Eighth and massacring her orphans in the name of becoming God and bring everyone who died back to life.

* AssholeVictim: More than any other diary owner. Compared to everyone else, he has no [[FreudianExcuse sympathetic backstory]] or [[VisionaryVillain grander ambition]] for what he does and seems motivated to kill purely ForTheEvulz, so his [[ButtMonkey many deadly misfortunes]] are quite deserved. Even in the 3rd World where everyone else gets a happy ending, his ultimate fate is to be arrested by Twelfth and visited by his captor in jail (which is admittedly a preferable ending compared to the ways he died in the previous timelines).

* SacrificialLamb: Killed off within the first chapters and first episode to demonstrate the rules and consequences of the survival game. Doubles as a RedShirt.

A police officer who wishes to stop the other crazy people with diaries. His "Case Diary" gives him information on all future crimes in his district as though he had already investigated them. He introduces himself early on as an ally to Yuki and Yuno, forming the Future Alliance.

* WhatCouldHaveBeen: In-universe example. According to Deus he was supposed to be among one of the final players of the game and not supposed to find out about his son's illness until much later. It turns out that his earlier demise was actually orchestrated by Mur Mur.

A 4-year-old boy who is left an orphan in the same incident that led to the Sixth's death. He is eager to prove himself to be a "super elite". His "Hyper Vision Diary" is a coloring book that displays pictures and summaries of three major events each day. It gives him plenty of time to plan his daily strategy, but it's not too helpful for predicting the immediate future.

* PetTheDog: He seriously enjoyed his time at Yuki's place (despite how twisted he viewed it as) and refused to put Yuki's mom in danger of his hide and seek game.

* BeingTorturedMakesYouEvil: She was throughly abused by the Omekatas, and ended in mentally/emotionally collapsing.

* BlindSeer: Her supposed powers of clairvoyancy make up for her poor eyesight. However, it's subverted when it's revealed her clairvoyant powers are a lie.

* DecoyDamsel: She plays the false role of a DamselInDistress in order to easily lure in Yuki and turn him against Yuno, using his habit to quickly trust people against him.

* GlassCannon: The "Clairvoyant Diary". She can use it to record what her cult members see and thus has a huge range, but it's very slow and hard to use. It also presents the largest target, which is problematic when a single hit from one of Yuki's darts is enough to count it as destroyed and she couldn't move it in time because Yuno cut her hand off earlier.

* HimeCut: Long hair all around, even bangs and sidelocks shows her status as a {{miko}} and YamatoNadeshiko looks. One side of the bangs hanging down in front of one eye hints that she herself is not even either.

* OmnicidalManiac: She wants to become god so she can destroy the entire world.

* RedEyesTakeWarning: Her eyes are blood red in the manga which serve to make her look even more maniacal when she starts to become more psychotic.

* YamatoNadeshiko: As a soft-spoken and frail-looking {{miko}} with a HimeCut, she looks the part of a traditional Japanese lady. However, her [[RapeAsBackstory past traumas]] have cause her true self to be far from it. She does really have the elegant and strong-willed personality in ''Paradox'' and the 3rd-world where her parents weren't murdered.

* BondVillainStupidity: They were the only diary owners who managed to both beat up Yukiteru and Yuno and take away their diaries during their first confrontation. Having the two at their mercy, they made them bring Yukiteru's father (secretly working for Eleventh) to them. After they got their hands on Yukiteru's dad, Marco stated that they didn't have any reason to keep Yukiteru and Yuno alive anymore. Instead of destroying their diaries that very moment... Marco and Ai didn't, and even challenged Yukiteru and Yuno to a rematch that resulted in the two recovering their diaries. Marco even mentioned that he could have simply destroyed the diaries, but that would be too easy and boring. After that happened, Ai admits that she and Marco should have simply destroyed the diaries.

* TheDividual: They're both The Seventh, working as a duo and rarely been seen without the other. Even their diaries' predictions only truly work thanks to them being always together.

* {{Foil}}: Towards Yukiteru and Yuno, since Marco and Ai are a BattleCouple who love each other in a much more genuine and healthy way.
* GracefulLoser: When it becomes obvious that they are going to die, they don't take Yukiteru and Yuno down with them and even give them their last parachute, making it possible for the two to escape from Sakurami Tower. Even though they killed each other's lover, they held no grudge against them for it and recognized that it was simply part of the game.

* OnlySaneMan: Out of all the diary owners, Marco and Ai seem the sanest, although this is shared with Kamado and Yuki before his badass upgrade.

* UndyingLoyalty: Both would rather die than betraying or abandoning each other.

* HeroAntagonist: She's actually a lot nicer and more sympathetic than the protagonists let alone the other antagonists. The only reason she's an antagonist is because she's a diary holder and the [[EvilVersusEvil morality of the series]], and even then she's only fighting because her orphanage's kids don't want to see her die.

* MoralityPet: Bacchus is completely antagonistic towards the other characters except Kamado. He acts like a true gentleman around her.
* NeutralFemale: Battle and personality wise, she prefers to have others fight for her, hence the Apprentice Diaries and only wants not to be bothered as she takes care of her kids.

* SuperpowerLottery: As Eleventh figures out, since she can provide a near infinite amount of diaries to possible wielders so she'll never have to fight, and those diaries can be easily replaced without the wielder dying like a natural Diary user. He even plans to gain omnipotence [[note]]since his Diary can read all the other Diary users' predictions[[/note]] combined with this power, providing him with near infinite army. Eighth on the other hand, does not show interest in this potential.

* UnusuallyUninterestingSight: No one in-verse except Mur Mur seem to be bothered at her appearance.
* WhatDoesSheSeeInHim: Her orphans' reactions to her going out with the Mayor in the 3rd-world.

* ActionFashionista: Played with, her initial outfit is very gothic lolita gimmicky, but post HeelFaceTurn she wears far more darker outfits that make her look far more impressive. She even makes a nurse outfit look awesome.

* AntiHero: She's willing to do anything to get victory, often in [[IncrediblyLamePun explosive ways]].

* BabiesEverAfter: The epilogue reveals Minene had children with 3rd-world Nishijima. As a bonus, her babies (most likely twins) have [[SuperpowerfulGenetics super powers due to her receiving some of Deus' powers]].

* DarkAndTroubledPast: Minene lost her parents when she was eight during a conflict caused by religious extremists and was forced to live a brutal life as a streetrat.

* {{Determinator}}: One of the longest lasting players in the survival game because she refuses to lie down and die. Deus picked her to ensure the game ran its course smoothly ''for a reason''.

* ElegantGothicLolita: She wears a lavender-colored gothic lolita-styled dress in her introduction. She drops it for a more subtle wear in her next appearances.

* GadgeteerGenius: Her bombs are all hand made.

* KarmaHoudini: Her body-count probably numbers in hundreds if not thousands, seeing as before the main story started she attacked not only clergymen, but also religious facilities; Twelfth does mention in ''Mosaic'' that she killed a lot of believers in her attacks. She also murdered an innocent rookie detective to steal her identity in ''Mosaic'', and there's also her school bombing early in the main story. As the 2nd-world where she did all of this ultimately gets destroyed, she ends up getting away with this, escaping from the 2nd-world and presumably living HappilyEverAfter with Nishijima in the 3rd-world. And on top of that, according to ''Redial'', she got to ''keep her God powers'', since it shows her flying in the sky with her kids.

* LargeHam: In both languages, her voice actress tends to devour the scenery when Minene is in full psycho killer mode.
* LickedByTheDog: She seems to be liked by a group of wild squirrels which follow her around.

* LoveRedeems: Nishijima was major motivation for her HeelFaceTurn. At the end, she gives up terrorism to marry 3rd-world Nishijima.

* MasterOfDisguise: She is able to fool people even if she's just wearing nurse outfit.

* NeverFoundTheBody: [[RedHerring We were led to believe she was completely obliterated by her heart bomb in the bank vault.]] It was later revealed that Deus had secretly pulled her out just before the bomb exploded, and in addition the anime shows the explosion was caused by a PortalCut when her bomb was suddenly disconnected from her just as she was being pulled to safety.

* NormallyIWouldBeDeadNow: Minene already had her eye pierced in her introduction, but as soon as the story starts focusing on her again, she takes some punishment. She narrowly survives a claymore that ends up blowing off her hand and causes her to lose a lot of blood, then after chasing Yukiteru down she manages to corner him only hesitate and give him the opportunity to shoot her in the abdomen, and she bleeds out quite a lot on the floor. Then after Yukiteru and Yuno leave her for dead to try to deal with Eleventh, Minene managed to get back up and walks up behind them to offer to sacrifice herself so they can get inside the safe. It takes her to break her own diary before she actually dies. And Deus even saves her from that, too. Oh yeah, and the new arm that she gets via his powers? Ripped off by Mur Mur. And even after that she still survives.

* NoSympathy: She calls Yuki out after he says he wants to become god so he can bring his parents back to life, saying that with such a reason anyone would want to be god while there is people like her who have suffered much more.
* NotSoDifferentRemark: Surprisingly, she says this to Yukiteru. When she saw him running through her minefield, choking on poisonous gas, or even the look on his face when he lost his parents, she was reminded of her own weakness in her childhood, and admits that she had a soft spot for him.

* PoisonousCaptive: Despite being captured by the Twelfth, she misses no chances mocking him when his plans go awry.

* SociopathicHero: In a very different way from [[VillainProtagonist Yuno]] in that she can also be merciless and have little care for anyone except herself and the guy she likes, but not nearly be as monstrously manipulative as the latter, being upfront about her intentions to the point of bluntness.

* SpannerInTheWorks: Becomes the most prominent one near the end of the story, through Deus. Her continued survival throughout the game causes Deus to deem her reliable enough to leave some of his power inside her. After she dies for [[NotQuiteDead the first time]], she manages to pull a BigDamnHeroes moment to save Yukiteru from the collapsing 2nd-world, and uses Deus' powers to follow Yuno back in time. She then leaves Yukiteru to make a phone call to Kurusu, telling him about his son's future condition and advising him to seek help for it before it's too late. Her actions caused a domino effect that allowed all of the other Diary Holders to prevent many of their personal tragedies and achieve a happy ending (except Third, although at least he gets prison instead of death).

* WineIsClassy: He has prized 30 year wine which he serves to his dogs.

* AllYourPowersCombined: He has the power to locate the other Diary users at all times he planned to take it a step further, using Eighth's power to create an omnipotence completed with an endless supply of replaceable Child Diary users.

* DidYouJustScamCthulhu: According to Deus, John promised that he would use the Future Diaries for the good of humanity if he agreed to help him create them. While John may believe he is indeed working towards a greater purpose, Deus doesn't seem too thrilled when he learns 11th's true intentions. Also, John clearly used his position as co-creator of the diaries to his advantage by making his diary one of the best. In the 3rd world, Deus seems to realize that John is trying to manipulate him, so he turns down all of the Mayor's proposals for a a new game.

* EvenEvilHasStandards: John proposes to Deus that the battle royale in the 3rd-world should be cancelled not only because he learns that in the 2nd-world the game resulted in his death, but also the realization that the winner most likely would not try to save the world. This is true to certain levels: Yukiteru would've grieved for millennia in a world of nothingness; Yuno've would just leapt back in time and created an eternal loop of battle royales; Tsubaki (hypothetically speaking) would've just destroyed the world into nothingness; and Deus helps us what would've happened if people like Minene or Takao won the battle royale.

* OddNameOut: His Future Diary is named The Watcher, does not follow the naming conventions of the others like the Case Diary or the Escape Diary. This is because it was one of the five prototype Future Diaries developed prior to the Survival Game, and it matches the names of that group (e.g. The Radar, The Searcher).

* ScrewTheRulesIMakeThem: It's eventually revealed that Bacchus help to create the rules of the game. So naturally it's convenient that he would also gift himself with the most [[SuperpowerLottery overpowered]] of the diaries.

* YouHaveOutlivedYourUsefulness: John kills his own secretary to stop Yukiteru's Future Diary from probing more informations and drastically change the future.

* TheHamSquad: He brainwashes four other people to act the way he does in an effort make it hard to determine which one is the real deal, and he does fight alongside these people.

* HeroicSacrifice: Attempts one after learning he has a Dead End to take out Tsubaki, but fails when he attacks Yuki, Yuno, and Tsubaki; Yuno slashing his throat with an axe. However, this may have been intentional since Yomotsu opened Yuki's mind to the possibility Tsubaki was misleading him -- [[TheCuckooLanderWasRight she was.]]

* KnightTemplar: Littering and murder are crimes which deserve equal punishment.

* MegaTwintails: In her initial appearances, she had huge pigtails that were bigger than her own head. She leaves her hair down afterwards, though. Their volume is somewhat HandWaved by ''Mosaic'' explaining that Mur Mur was the one altering her hair.

* AntiVillain: Most of the Diary Holders aren't bad people at heart, just doing what they have to in order to survive against 12 other individuals out to kill them. Some, even, are fighting for the sake of others more than themselves--Kamado for her orphans, Marco and Ai for each other, and Keigo for his son. [[spoiler:In the 3rd world where the game is not being played, everyone is much happier since they can lead normal lives, no killing necessary.]]

* CastFullOfCrazy: So {{God}} is dying and [[ThereCanBeOnlyOne wants twelve people to fight to the death in order to see who will be his replacement]]. Who better to choose than possibly the twelve craziest people on planet Earth? Even [[NonActionGuy our hero Yuki]] isn't immune. [[spoiler:After both his parents are murdered, one right in front of him, he [[BreakTheCutie snaps]] and proceeds to turn from a ShrinkingViolet into a full-blown, [[MoralEventHorizon line-crossing]] VillainProtagonist]]. It can be argued that only those without Diaries are safe from the madness, but even the mental condition of [[BadassNormal Nishijima]], [[KidDetective Akise]], and [[ThoseTwoGuys Yukiteru's three "friends"]] is up for debate.
* DysfunctionJunction: The whole cast is AxCrazy, ''especially'' [[{{Yandere}} Yuno]]. The main cast is comprised of a serial killer, a terrorist bomber, a prophetess of a self-proclaimed ReligionOfEvil who was also used as an unwilling [[RapeAsDrama sex toy]] by them in the past, a blind vigilante ruled by his own brand of justice, a {{Tykebomb}} who suffers from elitism, a CorruptCop, a man who is maniacally in love with his dogs and neglects his family, the local mayor who has Nazi-like views on how to evolve humanity by giving his citizens the power of the Future Diaries, and the lead Yukiteru Amano eventually snaps after certain incidents that force his hand all the while guarded by his AxCrazy StalkerWithACrush Yuno. The only sane characters are Yuki's friends, two diary owners who have a more stable relationship than Yuki and Yuno, and a careworker who has no interest in winning but her orphans want her to become God to make the world better.
* EarnYourHappyEnding: [[spoiler:In the 3rd world, everyone has a happier life as a result of never having had to play the game. Reisuke's parents are alive, Keigo's son is brought in for hospital treatment and recovers, Minene is HappilyMarried to Nishijima, Kamado becomes an OfficialCouple with John Bacchus and her orphanage is in no danger of closing, Tsubaki's cult is reformed into a Cult of Justice, Marco and Ai are married with a baby on the way, Tsukishima has a far better relationship with his daughter, and Hirasaka has opened a shop selling his merchandise. But the ultimate happy ending goes to Yuki and Yuno, who both become gods and reunite after 10,000 years, never to be separated again.]]

** The Ninth's diary (Escape) reflects her survivalist nature. [[spoiler: It also reflects [[BrokenBird her desire to escape from all the hardships she endured since childhood, and to be saved from it]].]]

** The Eleventh's diary (Watcher) reflects his megalomania [[spoiler: as well as his status as the creator of all diaries]].

* AscendToAHigherPlaneOfExistence: Becomes god after winning the Survival Game.

* DeadpanSnarker: In the English dub.

* EarnYourHappyEnding: [[spoiler:It takes three different universes and waiting thousands of years, but yes, in the end he gets to be with Yuno forever and ever. And they've both become gods, so not even death will part them.]]

* LongHairedPrettyBoy: The few times we see him without his mask.
* MalevolentMaskedMan: In his murder gear.

* TakeCareOfTheKids: Before eliminating himself he asks Minene to look after his son.

* BlushSticker: Has permanent ones on his cheeks.
* CheerfulChild: In ''Paradox'', since his parents aren't killed.
** In the 3rd-world for the same reasons and with the both of them being better parents.

* EvilOrphan: Since Yuno killed his parents.

* EvilOrphan: After her parents were killed and she went mad from being used as a SexSlave for the Omekata Cult.
* {{Expy}}: She's basically a {{genderflip}}ped version of [[Series/KamenRiderRyuki Miyuki Tezuka]].
* FanDisservice: How do we find out about her SexSlave deal? Through a flashback that starts with a barely pubescent Tsubaki lying naked on the floor, shivering and terrified, right before she's gang-raped by the men of the Omekata cult. Additionally, the scene where she decides to go the WoobieDestroyerOfWorlds route has her lying naked on the floor, murmuring madly about her purpose.

* MaskOfSanity: It doesn't take too long for it to slip.
* {{Miko}}: Though not by her own choice.

* OmniscientCouncilOfVagueness: The leader.

* ReflectionlessUselessEyes: Signifying her poor eyesight.
* ReligionOfEvil: The Omekata cult that she belongs to or rather, is imprisoned by. The AlternateTimeline shows them as a more benevolent group. It helps that the Kasuganos were still alive to lead it well.
** Even more tragic is the fact that in ''Paradox'' it's revealed that her parents were actually about to disband the cult [[GiveHimANormalLife in order to let Tsubaki lead a normal life]]. [[HeelFaceDoorSlam However, the second-in-command Funatsu wasn't having any of that so he offed Tsubaki's parents before they could do so, trapping her in the cult as a sex slave.]]
** Redial has the cult be reformed into a good religion and in ''Redial'' it becomes the [[JusticeWillPrevail Cult of Justice lead by her and Yomotsu]].

* StalkerWithACrush: The 3rd World's Tsubaki was this towards Akise. However, some of her friends thought she was that way to Kosaka... and... well...

* TearsOfRemorse: In the anime right before her death.

* UsedToBeASweetKid: As shown by her backstory before her parents were killed, Tsubaki was a nice little girl until she was turned into a SexSlave and decided to destroy the world.

* YamatoNadeshiko: A soft-spoken, frail-looking {{miko}} with a HimeCut looks the part. She does really have this personality in ''Paradox''.
** In the 3rd-world, we get to see how Tsubaki would've been like if her parents weren't murdered. She fits here ''to a T'', specially in regards to the will of iron - once Funatsu is uncovered as the would-be killer of the Kasuganos, Tsubaki delivers a RousingSpeech to the Omekatas as a whole to remind them of their benevolent and loving intentions.

* AntiVillain: They're enemies to Yuki and Yuno as part of the Survival Game, but they are ultimately good people, while Yuno is actually a VillainProtagonist.

* BondVillainStupidity: They were the only diary owners who managed to both beat up Yukiteru and Yuno and take away their diaries during their first confrontation. Having the two at their mercy, they made them bring Yukiteru's father (secretly working for Eleventh) to them. After they got their hands on Yukiteru's dad, Marco stated that they didn't have any reason to keep Yukiteru and Yuno alive anymore. Instead of destroying their diaries that very moment...

Marco even mentioned that he could have simply destroyed the diaries, but that would be too easy and boring. To her credit, after that happened Ai did admit that she and Marco should have simply destroyed the diaries.

* HeroAntagonist: Due to them being the [[OnlySaneMan Only Sane Couple]] with noble intentions unlike the others.

* MistakenForCheating: A RunningGag with this pair.

* TogetherInDeath: They die together during the collapse of the Sakurami Tower.

* RandomSmokingScene: From time to time.
* SmokingIsCool

* YouAreWorthHell: Marco decides to stay with Ai in the collapsing tower instead of escaping alone.

* AntiVillain: The "Villain in Name Only" variant. She's actually a lot nicer and more sympathetic than the protagonists let alone the other antagonists. The only reason she's a "villain" is because she's a diary holder and the [[EvilVersusEvil morality of the series]], and even then she's only fighting because her orphanage's kids don't want to see her die.

* HeroAntagonist: As the OnlySaneWoman with noble intentions, especially compared to [[VillainProtagonist Yuki]].

* NinetiesAntiHero: Fits this trope to a T. A badass DarkActionGirl with misanthropic tendencies, morally ambiguous, violent, and a MsFanservice (her later outfit even [[BareYourMidriff bares her midriff]]).

* BadassAndChildDuo: Strikes this with Yukiteru especially during the FinalBattle.

* BadassBoast: Known to give these.
* BadassInDistress: When briefly captured by the Twelfth.

* ByronicHero: Minene is an attractive terrorist bomber who is vicious, cynical, and ruthless due to a tragic childhood. Despite her brutal actions especially early on, she's far from completely evil since she gets plenty of sympathetic moments and comes around to help the protagonist several times.

* DeadpanSnarker: Especially post HeelFaceTurn.

* DivineIntervention: Experienced this in the first chapter of ''Mosaic'' and later on in the main story.

* EscapeArtist: She has the "Escape Diary", after all.

* GodivaHair: When captured by the Twelfth, who strips and chains her to a wall after tearing out her left eye.

* HeartbrokenBadass: After Nishijima dies protecting her.

* HospitalHottie: When she disguised herself as a nurse.
* HotGoddess: After being given half of Deus's powers.

* NormallyIWouldBeDeadNow: ''Damn'', where to begin? Minene already had her eye pierced in her introduction, but as soon as the story starts focusing on her again, she takes some punishment. She narrowly survives a claymore that ends up blowing off her hand and causes her to lose a lot of blood, then after chasing Yukiteru down she manages to corner him only hesitate and give him the opportunity to shoot her in the abdomen, and she bleeds out quite a lot on the floor. Then after Yukiteru and Yuno leave her for dead to try to deal with Eleventh, Minene managed to get back up and walks up behind them to offer to sacrifice herself so they can get inside the safe. It takes her to break her own diary before she actually dies. And Deus even saves her from that, too. Oh yeah, and the new arm that she gets via his powers? Ripped off by Mur Mur. And even after that she still survives.

* QuitYourWhining: Calls Yuki out after he says he wants to become god so he can bring his parents back to life, saying that with such a reason anyone would want to be god while there is people like her who has suffered much more.

* RetiredBadass: At the end of the story, she's married and living peacefully with 3rd-world Nishijima, having [[HeelFaceTurn given up the terrorist life]] in favor of being a stay-at-home mom.

* SemiDivine: After being given half of Deus' powers.
* SenselessSacrifice: Averted. Just as Ninth had broken her diary, Deus saved her from her vault explosion. The explosion itself failed to breach the vault as she had hoped, though.

* SourOutsideSadInside: She may be a cruel and bloodthirsty terrorist, but she's still haunted by the memory of her sad and helpless child self crying over the death of her parents.

* TheStrategist: Especially during the Fourth fight.

* TouchedByVorlons: Received half of Deus's remaining power when he noticed Mur Mur was unfairly influencing the game to go in Yuno's favor. Deus was hoping that she would use his power to help set the game back on track, and while she did try to honor his request, Yukiteru's decision to ScrewDestiny and help the 3rd-world's Yuno made her change course.

* {{Tsundere}}: Harsh type. She's an abrasive and fierce woman because of the environment she grew up in, but she can show a softer side to those she grows to care about like Nishijima and Yukiteru.

* UsedToBeASweetKid: She was one till her parents blew up.

* AccentRelapse: He speaks standard Japanese most of the time, but he slips into KansaiRegionalAccent during his last conversation with his daughter.

* WineIsClassy: His prized 30 year wine which he serves to his dogs.

* AesopAmnesia: In the 3rd-world, he cancels the game after learning of his death, understanding the risk is too high, even when the game is stacked in his favor... And then he's shown still pestering Deus with OTHER game ideas, also highly stacked in his favor.

* BaldOfEvil: As well as a [[ANaziByAnyOtherName a Nazi-esque liked minded thinker.]]

* PragmaticVillainy: At least in the 3rd-world. He convinces Deus to cancel the game and the creation of Future Diaries not because he has a change of heart or anything but because he learns that in the 2nd-world the game resulted in his death despite stacking the deck in his favor.

* AntiVillain: Seems to be the only diary holder who truly wants to do "heroic" deeds, as opposed to the other diary holders who were mostly selfish or neutral.

* [[WhiteMaskOfDoom White Mask of Justice]]: A round bag with a rope tied around it.

* InTheHood
* ThirteenIsUnlucky

* WeaponOfChoice: A machete.

* KnifeNut: Ai prefers throwing knives.

* BigBadEnsemble: There's the BigBadDuumvirate Yuno and Mur Mur and all the other Diary Holders including [[VillainProtagonist Yuki]] himself and the [[OnlySaneMan Only Sane People]] [[HeroAntagonist Ai, Marco and Kamado]].

* ICantBelieveAGuyLikeYouWouldNoticeMe: When Yuno looks his way for a moment in the first episode, he quickly brushes it off with "Nah, can't be," and is genuinely surprised that she even knew his name[[note]]He's shown conversing with her once [[FlashBack a year prior to the third episode]], although he himself barely remembers it, so presumably his low self-esteem would have made him assume she'd forgotten completely[[/note]]. Of course, his reaction to learning [[StalkerWithACrush the truth]] [[{{Yandere}} of the matter]] is a little less than enthusiastic.

* CharacterDevelopment: She slowly becomes much more heroic as the game goes on, although some of this overlaps with CharacterizationMarchesOn, as much of [[TheSociopath her]] [[ForTheEvulz initial]] [[BloodKnight personality]] seems downright incompatible with how [[CoolBigSis she's]] [[ByronicHeroine later]] [[DeadpanSnarker characterized.]]

* CoolBigSis: [[CharacterDevelopment Becomes]] [[LikeBrotherAndSister like one]] [[IntergenerationalFriendship to Yukiteru]] [[FireForgedFriends eventually]]. And also to 3rd-world Yuno in "Redial".

* AwesomeMcCoolname: Her name refers to both the goddess of knowledge and the god of the sea in the Roman mythos.

* IllGirl: Her sister Kasumi is hospitalized after an encounter with Third.

* NiceHat: He occasionally wears a brown hat atop.

%%* NiceHat

* SupernaturalIsPurple: In the anime, she has purple eyes which befits her supposed clairvoyant abilities.

* {{Tsundere}}: Surprisingly, shows shades of this towards Akise in ''Paradox''.

* RapunzelHair: Long black hair reaching her hips. Her hair is all the way down to her feet [[http://www.future-diary.tv/chara/6th.html in the anime]].

* YouGottaHaveBlueHair: She has blue hair.

* YouGottaHaveBlueHair: Ai's hair is dark blue.

* YouGottaHaveBlueHair: She has purple hair.

* TragicKeepsake: A handball given to her by her deceased mother. It gets lost later, and Tsubaki ''definitely'' loses it soon afterwards.

* CreepyChild: A little boy with a very diabolical mind.

* GlassCannon: The "Clairvoyant Diary". She can use it to record what her cult members see and thus has a huge range, but it's very slow and hard to use. It also presents the largest target, which is problematic when a single hit from one of Yuki's darts is enough to count it as destroyed.
