A timid boy who views life as though he were a casual bystander. His "Indifference 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. Has an...interesting relationship with Yuno.
Designated Victim: Considers himself this in early chapters, often being put in situations he does not want to be in. This trope comes and goes over the course of the story.
Disappeared Dad: His parents got a divorce and his father left him years ago. He came back though.
Easily Forgiven: Yuki's quite trusting of others and willing to give second chances, especially towards Yuno. A lot.
Kick the Dog: Happens several times to Yuki. Most notably when, he forgives his father for killing his mother, and everyone looks like it is going to be alright until John Balks' hitmen assassinate Yuki's dad.
Meaningful Name: His last name contains the kanji for "heaven" and can be read as heavenly field. It's fitting, considering his first name is a corruption of "Jupiter", the Roman God of Gods. He ends up winning the game of the second world among the other potential gods.
Necessarily Evil: Yuki becomes willing to kill the other diary owners if it means resurrecting his parents, although he admits he does not wish to do so, but is equally afraid to face life without his parents.
Necromantic: His eventual reason for trying to win the game.
Say My Name: When turns down the opportunity to go stargazing.
Spanner in the Works: He hijacks the entire future of the 3rd Survival game when he follows Yuno to the 3rd world, since his data entries in the 2nd game show up in 3rd world's John Balk's diary and warn him of the incoming disasters. It practically changes every diary holder's future and gives them happy endings.
Spell My Name with an S: Yuno calls him "Yuki" or "Yukki", depending on which version you're reading.
In messages and diary entries, ユッキ― is normally used, which is romanized as "Yukkii".
Tears of Fear: He tends to do this often in the beginning.
Took a Level in Badass: Hey, it was bound to happen eventually. He ditches the darts in favor of a machine gun, for one.
Weak, but Skilled: For a long time he's not much of a fighter, but Yuki is arguably the most skilled at using his diary both in and out of combat.
Yuno Gasai - The 2nd
Voiced by Tomosa Murata
A classmate of Yuki's who's obsessively stalking him, claiming to be madly in love with him. Her "Yukiteru Diary" tells her what's happening to Yuki at every 10-minute interval, and won't show anything unrelated to him except for her own DEAD END. Since Yuki's diary records everything except what happens to him, the two of them presumably make a formidable team. If only she was more comforting to be around...
Abduction Is Love: Yuno drugs and kidnaps Yuki to protect him until July 28th, chaining him to a chair. Yuki eventually breaks free thanks to his friends, and abandons Yuno. It doesn't last though.
Abusive Parents: Although Chapter 56 seems to indicate that only her mother was the abusive one.
Parental Neglect: Her father would work late hours and fail to notice her mother's escalating abuse.
Alternate Timeline: The Yuno that's currently obsessed with 'Yukki' is from one, and the third corpse is from the current world.
The All Solving Hammer: Yuno often resorts to pulling out her knife to deal with troubling situations. She uses a literal hammer to screw destiny and smash apart the space-time continuum to rescue Yukiteru at the end of the manga.
All Take and No Give: Yuno tries to convince herself and Yuki that their love has been fake, and they have been merely using one another, Yuki using Yuno as a guard whilst Yuno used Yuki as emotional support. She fails to convince Yuki or herself.
Because You Were Nice to Me: Yuno's devotion to Yukiteru stems from him jokingly making a marriage proposal to her right after she killed her parents, spurring her into devoting her future to him.
Beware the Nice Ones: She's described as a model student, everybody likes her, and all the boys are crazy about her. Except the one she's stalking, of course.
Broken Bird: Yuno is incredibly broken from having to kill her parents, going through the survival game once before, losing the only person that gave her a reason to live (Yukiteru), and having to go through it all again, killing her past self in the process.
Clingy Jealous Girl: She won't let anyone, male or female, get close to her beloved Yuki. Yuki's mother is a notable lucky one, since she was nice to Yuno and approved of their relationship.
Couldn't Find a Pen: When the first Yuno performs a time leap to the second world and kills her second self, the latter writes "Help!" on the wall using her own blood.
Death Seeker: Not very apparent, but Yuno heavily implies that she wants Yukiteru to be the winner of the game in the second world, rather than win it herself and repeat the whole scenario a third time. She only tries to kill him when he absolutely refuses to take her life, and she decides to repeat the game in the third world for another shot at setting him up to win while spending more time with him again. And even then, when Yukiteru told her to just stab him and be the winner of the second world's game, she decides to just kill herself anyway.
Driven to Suicide: Unwilling to kill Yuki, Yuno stabs herself to ensure he lives. Although she got better thanks to MurMur and Deus from the 3rd world combining her memories with her 3rd world self.
She actually tries to kill herself seconds before her death, provoking the third world Kurusu into firing a bullet at her. MurMur saves her.
Dull Eyes of Psychosis In episode 11 of the anime when she and Yukki are taken into the police station for questioning her eyes go dull when she decides to try to find a weapon.
Evil Sounds Deep: Much like B.B. Hood/ Bulleta, Yuno goes from squeaky and adorable to guttural and menacing whenever she's incredibly pissed.
Feminine Women Can Cook: Uses it to impress Yukiteru's mother. How feminine she is is up for debate though, considering her fallback plan if that didn't work was to use her "tools."
Future Me Scares Me: After being rebuked by her past self in the third world, Yuno actually starts shaking once she realizes how much she had changed when she lost all of her hope for the future, and seriously looks frightened at what she's become, having a minor My God, What Have I Done? moment.
Gas Chamber: In a surprising change from the manga, Yuno traps Akise, Mao and Kosaka in a room which is filling with gas. In the manga, she filled it with concrete.
Go Through Me: Yuno is more than willing to put herself on the line to protect Yuki.
Green-Eyed Monster: She already showed signs of this before the games began. It's very evident that she's jealous of Yuki's friends and tricks him into killing them all. And even though Akise didn't need to die to complete the game, she beheads him.
Heroic Sacrifice: Tries this when fighting Kurusu but it fails when the grenade she is holding is a flash grenade.
I Want My Beloved to Be Happy: She says she's willing to die for Yuki to ensure he wins the game, and even offers to let him kill her. She also goes through with it when Yukiteru flat out suggests she should kill him so she can have a place in this world.
Ill Kill You: "ARU AKISE, YOU WILL DIE HERE AND NOW!"
Karma Houdini: She has racked up the highest body count in the entire series. She's also responsible for the death of Yuki's friends, particularly Akise who she finished off herself. Yet she still gets her HAPPY END with Yuki despite the fact she just killed one of his best friends in cold blood. And she hasn't been punished for this and even if she's yelled at, it doesn't last long.
Kubrick Stare: Gives Yuki a seriously terrifying glare through his letterbox - while wishing him a good night.
Lack of Empathy: To everyone other than Yukiteru. When Tsubaki told her that she was going to destroy the world after becoming god Yuno's only gripe with that was that it would also kill Yukiteru. Late in the series she outright states that she doesn't care how many more people she'll kill in the future, because they are all useless pawns and because they'll be revived anyway after she goes back in time again (ignoring the fact that technically they would be different people).
Lightning Bruiser: She is faster than most characters and hits very hard.
Love Makes You Evil: At times, the lengths at which she goes to show her admiration comes across as something that can only be thought of by a Complete Monster.
Meaningful Name: Her full name can be read as "my wife Yuno". Seeing as Yukiteru is named for Jupiter though, the kanji for Yuno's given name is really "Juno" read as Yuno (In central European languages the letter J is pronounced like what Y is pronounced in English), so even more fittingly for Yukiteru, is the reading "my wife, Juno". Which is fitting, because Juno, just like her Greek-counterpart Hera, can get mad easily at anyone that stole Jupiter/Zeus' love, and will chase them down to the end of Earth (Then there's the fact that Juno is a war goddess too)
Obfuscating Stupidity: Though there were earlier hints, Fridge Logic tells you she has been displaying this the entire story. We find out she has played the survival game through before, so either she pretends not to know, or has repressed it completely.
Room Full of Crazy: An untouched room in Yuno's house that contains the corpses of her parents, and her second self who she murdered. Yuki finds it and ultimately changes the course of the game and the second world's timeline. Yuno eventually destroys the room and hides the evidence in a large pit behind her house.
The Sociopath: A very disturbing example she loves Yuki to the extreme but EVERYONE other than Yuki is just pawns or getting in the way showing no remorse killing them.
Unskilled, but Strong: Polar opposite of Yukki, in that her diary is almost completely useless except when paired with Yukki's, she is actually one of the strongest fighters. The only ones shown to best her in combat being Sevenths and Akise.
Villain Protagonist: Subverted in the later chapters when she becomes Yukiteru's enemy. She doubles back on that after she kills herself instead of him, though.
Villainous Breakdown: Has one towards the end of the manga when Yuki refuses to kill her, prompting her to try to kill him, leap back in time again to restart the game and kill herself again. She fails, realising she cannot kill Yuki and seals him in an illusionary world to escape him. She gets better though.
What the Hell, Hero?: She gets called out by Yuki all the time, but especially for kidnapping him and keeping him locked up for a week to "protect" him.
A teacher at Yuki's school who's secretly a serial killer. His "Murder Diary" gives him detailed information on the location of his intended victim, making it a powerful weapon for ruthlessly pursuing his target. However, it offers little protection.
Butt Monkey: Surprisingly often. He is the first diary owner to get killed, he kept killing himself several times over when MurMur first tried to give him his diary, he fell victim to one of Minene's amplified sound bombs in Mosaic, appeared in a flashback chapter to be accidentally (and comically) speared in the back by Yuno, and was given an electric shock in Paradox. In the penultimate chapter, he's pinned to the ground as he's apprehended by 12th, and he can be seen in the back of one of the final group shots, running from a few pursuers. MurMur wasn't too surprised that he was the first to go.
Crazy-Prepared: Apparently the costume he wears is not only bulletproof but somehow also bombproof. This comes in handy when Minene attacks him in Mosaic, as she quickly learns that her usual battle tactics are useless against him.
Implacable Man: While he doesn't get a chance to show this off in the main series, he proved himself to be this in Mosaic during his confrontation with Minene. He kept coming after her unrelentingly and wasn't even slowed down by the bombs exploding around him and by being shot at. Pity that his diary is nowhere near as invulnerable as the man himself.
Meaningful Name: The kanji in his last name, Hiyama, is read as "volcano". The Roman god in the Dii Consentes that he is associated with? Vulcan.
Sacrificial Lamb: Killed off within the first chapters and first episode to demonstrate the rules and consequences of the survival game. Doubles as a Red Shirt.
A police officer who wishes to stop the other crazy people with diaries. His "Investigation 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.
Logical Weakness: Kurusu's diary is the Investigation Diary, so as long as he's chasing down his suspects, he'll continue to get info on their next moves. Rather than trying to take him down directly, Minene goes to Nishijima and informs him that Kurusu was responsible for murdering Tenth and framing Yukki and Yuno. Once Nishijima arrests him, Kurusu loses the authority to continue his investigations, and thus his diary stops recording future events.
Manipulative Bastard: Implied to have been influencing events and manipulating others for a decent amount of time after his introduction, starting with letting Minene go free from the Omekata Temple.
Meaningful Name: Kurusu's is a bit harder to pin down than the others, but the kanji in his last name "kuru" means "to come" and as Mercury was the messenger to the others gods, he is probably closest to Mercury in the Dii Consentes.
Passing the Torch: In the anime, Kurusu leaves a record of the survival game to Nishijima, including the defunct diaries of the dead owners.
A 4-year-old boy who is left an orphan in the same incident that led to the 6th's death. He is eager to prove himself to be a "super elite". His "Super 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.
Abusive Parents/Parental Neglect: We see that Reisuke's parents weren't a happy family like we were made to believe. His parents were often fighting and he would be left in the corner of the room by himself. Now whether this contributed to his creepy tendencies is the series is up to interpretation, but one thing is for certain. He was seriously happy being taken care of by Yuki's mother.
Go Out with a SmileandGraceful Loser: After asking Yuno what will she do when she and Yukki face each other, Reisuke tells her to win The Game and dies smiling. His Diary reflects his last thoughts: "Hojou Reisuke is killed by Gasai Yuno. DEAD END. . . But I'm very happy!"
Hand Puppet: He carries a pair of hand puppets around with him, which he talks to as though they were real.
Pet the Dog: 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.
The priestess for the Omekata cult, who has been imprisoned in the cult's temple her entire life. Her parents were the founders of the cult, and after their deaths (or better said, their murders) she became its leader of sorts. Her "Thousand Leagues Eyes Diary" is a scroll that records what every worshipper in the cult sees, giving her much greater range than most other Diary Holders. While it provides a large amount of information, the scroll is also cumbersome and slow to use, making it difficult for her to react immediately to changes.
Angry Tears: Tsubaki cries these when her diary is destroyed in the manga right after she sees her old handball.
Attempted Rape: Tsubaki orders the cult members to strip and gang-rape the captive Yuno, in an attempt to lure the escaped Yukiteru out. He pulls a Big Damn Heroes and stops her.
Fan Disservice: How do we find out about her Sex Slave deal? Through a flashback that starts with her laying naked on the floor, shivering and terrified, right before she's gang-raped by the men of the Omekata cult.
Glass Cannon: The "Thousand Leagues Eye Diary". She can use it to record what her cult members say 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 Yukki's darts is enough to count it as destroyed.
Good Smoking, Evil Smoking: She pulls out a pipe and smokes on it when Yuno falls victim to a Distress Ball right after killing the 12th and this allows her to her trap them, Kurusu and Minene inside the Omekata temple.
Go Look at the Distraction: Yuki takes advantage of the fact her diary shows what her followers are looking at by throwing a ball then throwing a dart to destroy her diary when they're all looking the other way.
Manipulative Bitch: Tries to manipulate Yukki, Yuno, Kurusu, Minene, and Hirasaka for her own benefit.
Meaningful Name: Kasugano contains the kanji 日, which can be taken as sun or sunshine. She also poses as a prophetess and is representative of Apollo in the Dii Consentes.
It has been speculated Tsubaki may be a nod to the Roman goddess Proserpina, the goddess of springtime. She has the kanji (春) for springtime in her name, and further connecting to Proserpina by both being beautiful woman who spend much of their time in a hell they do not want to be in.
Peek-a-Bangs: Her right eye is almost always covered by her hair.
Rape As Backstory: After her parents (and the Omekata founders) were killed, Tsubaki was imprisoned and used as a Sex Slave by the cult while making her "pose" as the leaderess.
Religion of Evil: The Omekata cult that she belongs to or rather, is imprisoned by. The Alternate Timeline shows them as a more benevolent group, though. 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 in order to let Tsubaki lead a normal life. 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.
Scars Are Forever: Yuno chops off her left hand, therefore she can't handle the heavy "Thousand Leagues Eyes Diary" and is open for Yukki's definitive attack with his darts.
Yamato Nadeshiko: She makes herself look like one in the beginning, to lure Yukki away from Yuno. She does really have this personality in Paradox, though.
A pair of orphans in love with each other. Their "Exchange Diary" is actually two cell phones that report each other's immediate future. The couple displays excellent teamwork as they use their diaries to cover each other's weaknesses.
Adaptation Expansion: The anime expands more on their time in high school together rather than just the two flashback scenes in the manga in the tower where Marco and Ai first meet and where they decide to get married. The anime added in a rather dark story in which Ai is set up by her female classmates to be gang raped by a group of boys, with Marco finding her and her captors afterward. He then proceeds to beat down the group and even manages to kill one of her rapists. They later go the tower where Marco is almost Driven to Suicide over not being able to protect Ai, only to be stopped by Ai herself, who begs him not to leave her alone. It helps to add to his reason for not leaving Ai behind in the tower when it started to collapse.
Bond Villain Stupidity: 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 11th) 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. To her credit, after that happened Ai did admit that she and Marco should have simply destroyed the diaries.
Chekhov's Gunman: Ai appeared first, as one of Tsubaki's followers.
Graceful Losers: 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.
Impaled with Extreme Prejudice: Marco ended up impaled with a metal pipe during 7ths' second battle with Yukiteru and Yuno. Though it probably wasn't this but rather the collapse of the Sakurami Tower that killed him.
Meaningful Name: For both of them. 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 apprentice 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.
Only Sane Couple: Out of all the diary owners, Marco and Ai seem the sanest, although this is shared with Kamado and Yuki before his Badass upgrade.
A very...uniquely shaped woman who runs an orphanage. Her "Blog Diary" is actually a server that can be accessed by the people she allows, giving each person their own "Apprentice Diary" that can predict the future in various ways. She hasn't shown much interest in winning the game, but the children at her orphanage willingly fight to protect her by eliminating the other Diary Holders.
Harmless Villain: She doesn't want to win the game, and relatively speaking she hasn't shown herself to be nearly as crazy or murderous as the other Diary Holders.
Meaningful Name: Kamado can mean "hearth", which is one of the domains that Vesta was goddess over. "Ueshita" sounds like "Vesta" (Ueshita/Weshita/Wesuta). Just as well, Ueshita runs an Orphanage of Love and gives a place for orphans to stay, and Vesta was also the goddess of family and the home.
A terrorist bomber raging against the world. Her "Escape Diary" explores each possible option and recommends the best course of action to escape danger, making it very helpful for avoiding death. It will still display a DEAD END when things are stacked too heavily against her, though.
Action Bomb: Her "heart bomb" will explode as soon as her heart stops.
Armor-Piercing Question: Asked this by 12th in the second chapter of Mosaic. The 12th asks Minene why she hates God so much, and after getting a weak response, he then asks what happens after she kills God. He then points out that if she takes his place after killing him, then she would be God herself. Minene can't respond and 12th tells her that she's just a person who hates the world because of the hardships she had to suffer.
Babies Ever After: 2nd world Minene with 3rd world Masumi. Much to the chagrin of her husband, he still has to catch and arrest his wife's counterpart, who is still a terrorist.
As a bonus, her babies (most likely twins) have super powers due to her receiving some of Deus' powers.
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.
Divine Intervention: Experienced this in the first chapter of Mosaicand later on in the main story.
Friend To All Children: With the exception of her school bombing early in the story (which she only targeted in the first place to lure out 4th, since she only ever targets religious places/figures), she subtly displays traits of this. First, after their rough initial meeting, she becomes friendlier towards Yukiteru and takes on more of a mentor role towards him in later story arcs. She also acts friendly with and shows good will towards 5th, going to great lengths to return his hand puppets when he was being stubborn. And while she is hiding undercover as a nurse, she mentions to Akise that she doesn't mind talking to and looking after the children in the hospital. She later also tries to scare Yukiteru's classmates out of helping her stop 11th for fear of their safety (even though they ended up helping her anyways). Probably hinting that she wouldn't make a bad mother in the future.
Godiva Hair: When captured by the 12th, who strips and chains her to a wall after tearing her left eye.
I Was Just Passing Through: Passes off several of her kind actions as this, like rescuing Yukiteru and Yuno from Reisuke's gas trap and informing Kurusu of his son's condition when she told Yukiteru that she was just going to wander off and do her own thing in the 3rd world.
Karma Houdini: Her bodycount probably numbers in hundreds if not thousands, seeing as before the main story started she attacked not only clergymen, but also religious facilities; 12th 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 happily ever after with Nishijima in the 3rd world.
Kill the God: Her eventual goal once she wins the game. Though she wouldn't have to work hard on that goal since Deus is dying anyways. What's more, it's lightly hinted that when Deus transferred half of his remaining power to Minene, it actually sped up his coming death, leading to the world to start collapsing earlier than was expected. She ended up achieving her goal, in a way.
Licked by the Dog: She seems to be liked by a group of wild squirrels which follow her around.
Love Redeems: Kinda. She gives up terrorism and marries Nishijima in the third world, but her other terrorist-bomber self is still running around there.
Mad Bomber: She bombs churches and assassinates religious figures.
Meaningful Name: As it turns out, Minene is named for two gods. Her first name, Minene, is an obvious corruption of Minerva, but her last name also contains the kanji for rain 雨 (ame), which corresponds to Neptune in the Dii Consentes. It still makes sense though, since Minerva and Neptune are usually paired together in the Dii Consentes.
Mega Twintails: In her initial appearances. She leaves her hair down after though.
Their volume is somewhat Hand Waved by Mosaic explaining that MurMur was the one altering her hair.
Nay Theist: She's fighting to gain the powers of a god, yet refuses to acknowledge the very god who gave her the Diary.
Not so Different: 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.
She also gets a bit of this with the Fifth in Mosaic when she asks if he's going to take revenge for his parents. It's probably why she was so intent on returning his dolls.
Rasputinian Death: 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 11th, 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, so the whole thing was dragged out to be subverted. Oh yeah, and the new arm that she gets via his powers? Ripped off by MurMur.
Satisfied Street Rat: She lost her parents in a religious struggle in the middle east and had to fend for herself in a place where she didn't even know the language, becoming a hardened Badass who would eventually target religious buildings and figures in her terrorist bombings.
Senseless Sacrifice: Averted. Just as 9th had broken her diary, Deus saved her from her vault explosion.
She Cleans Up Nicely: Before and after the school bombing, she lets her hair down.
Spanner in the Works: 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 the first time, she manages to pull a Big Damn Heroes moment to save Yukiteru from the collapsing second 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. Her actions caused a domino effect that allowed all of the other Diary Holders (minus Third) to prevent many of their personal tragedies and achieve a happy ending.
Touched by Vorlons: Received half of Deus' remaining power when he noticed MuruMuru 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 Screw Destiny and help the 3rd world's Yuno made her change course.
A man who loves his dogs more than anything else. His "Rearing Diary" lets him check up on and control his army of dogs, which he can command to attack his enemies.
Kansai Regional Accent: He speaks standard Japanese most of the time, but he slips into the dialect during his last conversation with his daughter.
Meaningful Name: Tsukishima (月島) contains the kanji for moon, and his first name, Karyuudo, is read as "hunter". Goddess of the moon and hunting? That's Diana in the Dii Consentes.
The mayor of Sakurami and the one who suggested the idea of the Future Diary. His "Watcher Diary" can spy on the contents of all other Future Diaries, making him one of the most formidable Diary Holders. His Evil Plan is to link up the 8th's Diary to the city's main server, turning every phone into an "Apprentice Future Diary" and giving him nigh-omniscience.
Affably Evil: Subverted. He acts like a gentleman around Kamado, but is completely antagonistic towards the other characters.
Badass: Just on one occasion, but still: when Minene made her first attack on him, he caught the grenade she threw at him without even looking in her direction, then nonchalantly threw the grenade back at Minene.
Hoist by His Own Petard: Balks hides himself in a vault in the bank once run by Yuno's parents, believing Yuno will be unable to use the retinal scanner to get in, under the belief she is not the real Yuno. It turns out she is, and Balks has pretty much got himself into a corner.
Meaningful Name: His last name "Balks" can also be read as "Bacchus", the same as the Roman god. Tokyo Pop seemed to pick up on the reference and translated his name using the same spelling "Bacchus". Fitting in with "Evil Foreigner" above, he's also one of the only diary holders whose namesake isn't a god listed in the Dii Consentes, along with Yomotsu Hirasaka.
It probably explains why his and Yomotsu's diaries were modified last, making them 11th and 12th, respectively.
A Nazi by Any Other Name: His ultimate goal is to use the power of Future Diaries to turn the people of Sakurami into a master race.
Pragmatic Villainy: 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.
Ship Tease: Has a bit of it with Kamado. He acts much more gentlemanly towards her than towards other characters; in the manga after she undresses to reveal where she hid her Future Diary, he even gives her his own coat so she wouldn't feel uneasy. And in one of the closing panels in chapter 59 they can be seen walking together. The scene where he gives her his coat wasn't included in the anime but, on the other hand, in the last episode they are unambiguously shown to be a couple in the third world.
Smug Snake: Very condescending towards First and Ninth in their attempts to reach him inside the vault.
A blind man who wants to be a superhero. His "Justice Diary" is an audio recorder that warns him of acts of "injustice" before they occur. It also gives him some sort of hypnosis power. While he claims to be a "Hero of Justice", his actions mark him more as a crazed vigilante.
All of the Other Reindeer: Assuming his backstory shown in the MurMur segment at the end of episode 5 is canon, before he got his Future Diary his attempts at being a superhero and helping others resulted in people mocking him and throwing rocks at him if he was lucky or mistaking him for a criminal and arresting him if he wasn't.
The Faceless: He likes to wear a mask, and his face is never clearly shown until the last episode of the anime.
Heroic Sacrifice: 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 - she was.
Spandex, Latex, or Leather: His comical superhero outfit consists of a full-body spandex suit with a sphere-like mask.
Transformation Sequence: His "transformation" sequence (which is simply him putting on the different articles of his costume and screeching "HENSHIIIN" the entire time) falls somewhere between hilarious and disturbing.
Vigilante Man: Goes back and forth between a heroic and villainous type.
The thirteenth diary holder who exclusively appears in the video game Future Diary: The 13th Diary Owner. Not much is known about her, but she is a school student who wears a yellow raincoat. Her Future Diary is a video diary. Her little sister Kasumi is in hospital after being attacked by Takao Hiyama.
The Lord of Time and Space who has called forth the Diary Holders to participate in a battle royale. He is dying soon, so he wishes to pass on his power to the winner of the contest.
A God Am I: Well, he really is a God, but he actively goads the other diary holders into this behavior to encourage them in the game.
God Is Dying: Part of the reason why he created the survival game.
God Is Evil: Sure, he's about to die and taking the world down with him, but picking his successor by forcing mostly innocent people to fight a battle royale for the lulz?
God Is Flawed: He leans a bit closer to this in that he wants the survival game to play out fairly between the players and without outside intervention from himself or MurMur, and honestly can't see the problem in it so long as he's kept entertained and his successor is chosen. He is also very willing to cancel the whole game entirely when John Balks decides to stop the Future Diary Project from developing further in the third world.
Half Truth: When Yukiteru asks him to revive Rea, Deus replies than it's impossible. When questioned why that is so, he states that he's dying and losing his power. While he doesn't outright lie, the way he phrases his reply makes it look like it's only impossible for him in particular and that the new god will be able to revive Rea; he doesn't mention that even a god would only be able to revive the body but not the soul. As his later conversation with Akise shows, it's not that Deus himself isn't aware of this.
Imaginary Friend: Yuki at first believes Deus to be one. Turns out he isn't.
Kick the Dog: When he tells the truth to Akise about being an Artificial Human, Akise declares that his love for Yukiteru is genuine. Deus, who is nearly finished in returning Akise to the Akashic Records, tells Akise that those feelings were also programmed into him. Given that Akise is very serious about his love for Yukiteru, it's a low blow, even if it ended up being true.
He also seriously considers following Eleventh's suggestion to remove Yukiteru and Yuno from the game when they fail to show any activity for five consecutive days. Given that Deus was pressed for time in choosing his successor before he dies, this ends up being more of a Kick the Dog moment for Eleventh than Deus.
Pals With Jesus: Pretty much everyone who is able to visit the Hall of Causality is this to him since he's a pretty chill God. Special mention goes to Yukiteru though, whom Deus clearly favors over everyone else.
Big Bad: Seems like it for awhile, and even after Yuno took her place as the final boss, still seems more malevolent than her.
Bitch in Sheep's Clothing: More evident in Paradox. Her jerkass personality seems to be directed at Akise only to the point that it makes it seem like she's homophobic. Heck, she goes as far as calling him a fag in Paradox. In the main series, she shows her true personality after Deus dies.
Bunny-Ears Lawyer: She's a silly character for the most part (despite the occasional slip up, like the incident that sets up the storyline for Paradox), but she knows how to do her job. And she is a lot more competent and devious than she first appears.
Butt Monkey: In Paradox. Might lean into being The Chew Toy depending on the fans that read the story.
Deceptive Disciple / Bastard Understudy: Subverted in the end. It turns out she was loyal to Yuno, most likely because she became god in the first world.
Enigmatic Minion: Towards the middle of the story, MurMur starts hinting that she knows more than she lets on, perhaps more than Deus, and manipulates the game accordingly. Her true purpose isn't revealed until the full story about Yuno being MurMur's real god comes to light.
Just Between You and Me: Shows Yukiteru the past events of the first world right after Yuno starts to attack him to "make the game more interesting". Since she was working under Yuno, she was probably expecting him to die right after showing him the past world. And she would've been right had it not been for Minene's interference.
Meaningful Name: Named for the Goetic demon Murmur. She also carries a small trumpet on her hip to reinforce the namesake.
She eventually wears a crown just like the Murmur from myth is said to wear after Deus death.
Restraining Bolt: The bracelets she wears keep her from acting against Deus's will, or so he thought. In chapter 57, she takes them off.
She continues to serve God's will. It's just that her God is no longer Deus.
Spell My Name with an S: Although both fan translations of the Manga and the official Tokyopop release spelled her name "MuruMuru", the opening to the anime displays her name as "MurMur".
Verbal Tic: Ends every sentence with "-noja", the equivalent of the standard Japanese explanatory expression "-noda" in some Western Japanese dialects*
namely, the ones spoken in Okayama, Hiroshima and Yamaguchi prefectures, according to the Japanese
Yuki's classmate who develops a peculiar interest in him. He desires to be a great detective, and dives head-first into the mysteries surrounding the Diary Holders. He has the "Detective Diary" which predicts other diary owners' actions regardless of how they change the future. In Paradox, however, he borrows Yukiteru's "Indifference Diary".
Always Save the Girl: In Mirai Nikki: Paradox, in regards to Yuki and Tsubaki (though it might be just part of his plan in the latter's case).
Badass Abnormal: After he's revealed to be an Artificial Human created by Deus to observe the game, he receives a future diary through the 8th's server system and uses it to become a terrifying opponent for even Yuno.
Didn't See That Coming: Yuno having two Diaries. Of course no one besides MurMur or Yuno would have seen it coming.
Beware the Nice Ones: Akise is one of the nicer characters in the series. He rarely gets pissed off even when Yuno tries to kill him multiple times. The only time he lost it was when he spared Yuno and she responds by calling Yuki and lying to him and manipulates him to kill his friends.
Break the Cutie: His confrontation with Deus. It's a real shocker to find out that you're not even human and then denied the things that made you you. The pride in his detective skills as well as his love for Yuki were denied by God himself. Fortunately, he breaks out of this quickly.
Crazy-Prepared: Near the beginning of his final fight with Yuno.
Dying Declaration of Love: Subverted. Akise doesn't get a chance to tell how he feels for Yuki. He instead, texts the final message to Yuki about Yuno before she beheads him.
Expy: His similarities to Kaworu of Neon Genesis Evangelion go way past the point of being unintentional. Like Kaworu, he's a White-Haired Pretty Boy voiced by Akira Ishida who seems to be in love with the meek main character, and turns out to be an "angel" and later dies of decapitation.
Heroic Albino: Has shown shades of this in the actual series. Played straight in Paradox.
Heroic BSOD/Heroic RROD: When he confronts Deus on his own and finds out that he's an Artificial Human, he tries to prove that everything he had done up to that point wasn't programmed into him, but with each of Deus' rejections, his body decayed more and more as it was returned into Deus' Akashic Records. When he finally tried declare that his love for Yukiteru was real, Deus rejected that as well, and said it was also something that he willed to happen as God.
Heroic Resolve: Even though he was deleted and Deus proved that everything he did was planned out as God's will, he decides to forge his own future from that point on, creates his own future diary with 8th's server system, and swears to protect Yukiteru.
I Did What I Had to Do: During his last meeting with Yukiteru he claims that not stopping him from killing Mao and Kousaka was necessary, because it meant that the future predicted by his diary wouldn't change and that he would manage to kill Yuno. It's never made clear whether the readers are supposed to agree with Akise that letting Mao and Kousaka die was really necessary.
If I Can\'t Have You: An interpretation of his character concerning Yuki. He generally tries to keep Yuki away from Yuno (with good reasons mind you) but his final confession before he's killed can be seen as this so Yuno can't have him. It seems to work...but then it doesn't since by then, Yuki is already too far in with his relationship with Yuno.
If It's You, It's Okay: Akise claims that he's not into boys. However, he says that he just loves Yuki.
I Gave My Word: Akise is one of the few characters that constantly tells the truth to Yuki and never breaks his promise to him. But it was almost certainly averted with his promise to Kamado that he would't hand her over to Yukiteru in exchange for giving him an apprentice future diary. When Yukiteru found him after killing Mao and Kousaka, Akise was guarding unconscious Kamado. As she was awake and running away from Yukiteru while his friends were stopping him just in the previous chapter, Akise must have been the one who caught her and knocked her out, as nobody else could have done that. And he almost certainly did that with an intention of letting Yukiteru kill her or even kiling her himself, as he already stated that he wanted Yukiteru to be god.
Last Kiss: More like a stolen kiss but it was probably his first with Yuki and his last as Yuno kills him shortly afterwards.
The Messiah: In Paradox. He does all in his power to prevent the many casualties that Yuno originally caused in the main series. This includes not involving anyone during 9th's hostage situation and battling her on his own (albeit using MurMur as a fake hostage as well), figuring out what the cult was planning to do to 6th and save her, prevent 5th from becoming murderous by saving his parents and making the 12th realize that his view of the world is wrong and he can still redeem himself by saving another. He even gets to befriend 7th and 8th in said situation. Naturally, the only person who does not like this attitude one bit is MurMur.
Murder Is the Best Solution: Subverted. Unlike Yuno, Akise does all in his power to avoid killing someone. This backfires on him in the end.
Nice Guy: For the most part. He didn't kill Yuno when he had the chance because of his better judgment. However, he soon regrets it, and she kills him.
No Good Deed Goes Unpunished: Despite Akise sparing Yuno's life when he had the upper hand, she manages to trick his diary by forcing his blade into her abdomen, fulfilling his diary's prophecy and forcing him to waste his time in bandaging her wound so that she won't die, knowing that Yukiteru would lose his trust in Akise if he had allowed Yuno to bleed out. Once he runs to help the others, Yuno calls Yukiteru to lie to him about Akise and his friends, causing Hinata, Mao, and Kousaka to die as a result. Akise even relents that he should have killed her instead of letting her live.
Red Eyes, Take Warning: He's a subversion of the trope as despite being a very subtle yandere, he's mostly a nice person overall. Double Subverted in his final confrontation with Yuno; he went for the kill and was only thwarted when Yuno was revealed to be holding out the second Yuno's future diary for him to smash.
Purposely made to be this way so that he would watch over Yukiteru for Deus.
Ship Tease: A lot of this with Yukiteru in the main story and Paradox. Also has a fair amount with Tsubaki in Paradox, too.
Shipper on Deck: Subverted. At first he seems to be pushing Yuki to go out with Yuno going as far as to set them up for a date that could very well make them closer than before. However, this is so he can trespass in Yuno's home hoping to dig up information that will make Yuki realize how much of a bad person she is.
Spanner in the Works: The reason 10th got caught in the first place is that he assumed that Akise was a diary wielder and was out to kill him. These turn of events later lead to his death.
He almost ruins MurMur's plans in Paradox by preventing the tragedies that happen to nearly all the characters.
In the main series. His dying message to Yukiteru serves as a catalyst which triggers the events leading to the final act.
Strange Boy: According to Hinata and Mao, he's considered very strange especially since they claim he "plays detective" rather than being an actual detective.
Yandere: Much more subtle than Yuno, but it seems to be there. While usually nice for everyone, he did prove on a few occassions that he's willing to sacrifice others for Yukiteru's sake. Once, without knowing whether it'll kill him or not, he instructed Yukiteru to break Kousaka's apprentice diary, to see what might happen to him and to prevent 8th from getting information from Kousaka's diary. Yukiteru did as he was told without any objections. Thankfully, since Kousaka wasn't bound by the game like the other diary holders, he lived.
Made even more obvious after Hinata's death, when Akise's diary predicted that Yukiteru would also kill Mao and Kousaka. Despite arriving at the scene in time to prevent this, Akise decided to abandon them to their fates instead. When questioned about this decision by Yukiteru, he replied that his diary also predicted that he's going to kill Yuno in a few minutes, so he didn't want to do anything that might have changed that future.
His vague yandere tendencies become less vague in Paradox, in that he is much more open about his desire to make sure that Yukiteru becomes a god.
Another of Yuki's classmates, who quickly becomes friends with him. She's actually the daughter of the 10th Diary Holder, and is commanding the dogs in place of her father, because she's desperate for her father's approval. She borrows the "Breeder's Diary" at first, but her real Future Diary is the "Friend Diary", which predicts her interactions with her friends.
Adaptation Dye Job: Hinata's hair in the anime is closer to being brunette rather than orange like in the manga.
Big Breasts, Big Deal: Mostly Type 3 with some Type 1; Hinata's size isn't really brought up too much, but she does get flustered whenever Mao is admiring her assets.
Dark Magical Girl: She may not have the powers (unless you count the Diary), but she does have the personality and backstory.
Heel Face Turn: It tends to be forgotten, but in the story arc when she was first introduced she held Yukiteru hostage at knife point and tried to kill him via Diary.
Psycho Lesbian: Helps Hinata in her scheme to kill Akise, despite the fact that Hinata was only doing it to gain her father's approval. After Hinata apologizes for taking advantage of Mao's feelings, she actually tries to kill Yukiteru. Hinata herself doesn't really snap until Yuno stabs Mao.
Yuki's classmate, who doesn't like him much (the feeling's mutual). He enjoys blogging on his cell phone, which inadvertently connects him to the 8th's Diary. He gets the "Kousaka King Diary" while attempting to rescue Yuki from Yuno. It predicts his "brilliant moments". Later in the series, it is upgraded to the "Neo Kousaka King Diary", which predicts the brilliant moments of the people around him as well.
A police officer who works under Kurusu. Despite not having a Diary, he becomes deeply involved in the conflict between the Diary Holders, and specially after meeting and falling for Minene.
Badass Normal: Notable in that his lack of a Diary is key to his effectiveness.
Career Versus Woman: Has to choose between doing his job as a policeman and later being the 11th's bodyguard and his feelings for Minene. He chooses Minene, and even proposes to her.
The Charmer: Though he (unknowingly, at first) ends up mostly just pursuing Minene every time.
Go Out with a Smile: In the manga, the last thing he did before he died was give one final smile to Minene.
Good Cop/Bad Cop: With him as the good cop and Kurusu as the bad cop.
Heroic Sacrifice: And Yuki gets blamed for it, although he did actually use Minene and Nishijima as decoys to clear the path ahead to go to John Balks.
The Slacker: Shown to be like this during his time as a rookie in the third world. He seems to be a more serious and competitent cop during the time of the actual story.
Yuki's mother who's usually away from home due to work. Despite this, she and Yukiteru are shown to have a stable and loving relationship. She approves of Yuno and Yuki as a couple, against Yuki's ignored protests. She is killed when her husband stabs her in desperation after he escapes the collapsing Sakurami Tower.
Dead Little Sister: Becomes this to Yukiteru after her husband stabs her in a moment of extreme stress and desperation. If there was any doubt of how much Yuki depended on her/how much he loved her, it's certainly cleared away not too long after when we see just how broken he becomes without her.
Meaningful Name: If Yukiteru is Jupiter (see his section above), then Rea is his Titaness mother Rhea.
Parental Obliviousness: Especially towards Yuno's...behavior. Really, when your son is on the run from the law, then disappears for a week after being exonerated and comes back incredibly nervous, you should be at least a little concerned.
Kurou Amano
Yuki's father who left after a divorce years ago. He and Yukiteru are shown spending some father-son bonding after a long time since the divorce around 2/3 into the manga, where he is introduced. He really seems to care for Yukiteru and Rea or so we are led to believe (until that is subverted too). He is killed by the 11th's henchmen.
Dead Little Sister: His death at the hands of the 11th's henchmen promp Yuki to momentarily go berserk, Take A Level In Badass, depend fully on Yuno, and resolve to become God.
It's All About Me: His most prominent flaw is that he puts himself and his own troubles before everyone else.
Double Subversion: He still cares for Yuki and Rea... until we're shown that this is a facade to find and break Yuki's Diary so that the 11th will clear the 3 million yen debt he owes. However, he doesn't seem to know that doing so will kill Yuki. Later, he stabs his ex-wife when she stops him from escaping. He stabs her (which kills her) in order to run and appears to be about to eliminate the evidence and escape...until we learn that he had retrieved a telescope he had been previously forced to pawn so that he could gaze at the stars and calm himself before turning himself in. He also asks Yuki to start over with him when his sentence is over, to which he agrees. Too bad the 11th's henchmen chose to butt in at this time.
Meaningful Name: Fitting with the rest of his family's Theme Naming, "Kurou" resembles "Cronus". Not to mention how he tries to kill his son...
Pet the Dog: Despite trying to sell Yuki out to the enemy, and murdering his mother, it turns out those were just horrible mistakes that he never meant to happen and all he wanted was for the family to be happy... and then he dies.
Redemption Equals Death: Yuki was willing to give him another chance after he turned himself and fulfilled his sentence, but the 11th's men killed him before he could do any of that. Ergo, Yuki forgave him completely and then freaks out on the murderers.
Another World Characters
Arata Hoshino
The main protagonist of the drama. A slacker of a college student, Arata has no interest in looking ahead to his future. Given a Future Diary by his friend Rui Moriguchi, Arata finds himself in a future he does not want, accompanied by his own stalker Yuno Furusaki.
Badass: Compared to Yuki, Arata is a courageous person, willing to take on the serial killer to protect Yuno.
Comes Great Responsibility: Shortly after Arata gets his Future Diary, he spends a night gambling and partying with friends following his diary's predictions.
Expy: Of Yuki, although there's little to compare between the two other than being stalked by Yuno.
Extreme Doormat: At first, but his desire to stop the game puts away with this trope.
Arata's personal stalker and love interest. Yuno is devoted to Arata and has Yandere qualities to her, but maintains a more subtle sense of madness to her. She refers to Arata as "A-kun", her diary able predicting everything Arata does or even feels. Like the original Yuno, she is implied to have had a troubled childhood and may have one or two secrets hidden in her house.
Abusive Parents: Her mother is implied to have locked her in a closet countless times. Both of her parents are dead by the time the series starts.
Lack of Empathy: Subverted, since she seems to accept the company of Arata's friends, despite claiming that Rui would betray him.
Room Full of Crazy: Two rooms in her house. The closet where she was trapped by her mother, and the basement where someone is trapped behind a metal door.
Arata's college friend. He gives Arata, Yuno, Kinjiro and Megumi their Future Diaries in order to find his kidnapped sister Haruna. To atone, he helps Arata and Kinjiro in the survival game.
Necessary Evil: Had to put his friends in the survival game to save Haruna.
Haruna Okie
Rui's sister. She is an ill girl and hospitalised repeatedly. Like Rui, she feels guilty for playing a part in setting up the survival game and aids Arata. Yuno seems to dislike her.
Ship Tease: It is implied she has a crush on Arata.
Kinjiro Haginoto
A 33-year old police officer who receives a Future Diary from Rui. Becoming an ally to Rui and Arata, Kinjiro uses his diary's ability to predict crimes to identify the other diary owners. He acts quite laidback and detached, but is quite smart and resourceful.
A woman of Kinjiro's age who first appears in hospital, but is later kidnapped by Tohru Kibe. She met Kinjiro six months prior to the survival game, unsure of her dreams and was abused by her husband. After her husband dies by her hand, Rinko ends up in hospital with Laser-Guided Amnesia.
Laser-Guided Amnesia: When her abusive husband tried to commit a double suicide with her, she refused and pushed him off a balcony to his death, realising the enormity of what she had done and gained amnesia. May double as Plausible Deniability.
Also known as "Southpaw", Yousuke Okuda is a Serial Killer who has a Future Diary. He targets anyone who possesses one of the limited release cell phones, eventually attacking Arata and Yuno. He is very tactical, his diary giving him numerous strategies to kill his targets. However, he is shown to be a troubled man, caring for a comatose mother.
Abusive Parents: His ill, comatose mother treated him like garbage and is very strict and demanding. But, Yousuke is devoted to her.
Crazy-Prepared: His diary has countless strategies on how to catch and kill his victims. However, each strategy has a probability factor for success and the highest is 85%.
Villainous Breakdown: After learning Deus merely used him to start the survival game, and finding he has an inescapable Dead End, Yousuke has one hell of a breakdown.
A 17-year old high school student who studied under Rui, and was given a Future Diary by him. Living a reasonably unfair life, Megumi is at the end of her rope and considers playing the game or not. But unforeseen events end up making the choice for her. Megumi is a skilled archer, and lives with her mother and step-father who are expecting a baby.
Angry Tears: After Arata destroys her diary, realising he betrayed her trust even though she provoked him.
Parental Neglect: Her mother scolds her all the time, her step-father seems well-meaning but Megumi refuses to call him "Dad", and they both have a child coming, likely meaning Megumi will be neglected even more so.
The Power Of Trust: Megumi has tried to revitalise her trust in others, but after saving a girl who ended up bullying her, she has given up all hope.
Kurou Hoshino
Arata's father who helped develop the Future Diaries. He works for the Chronus Seed Corporation in the development department. He abruptly divorces his wife, but his reasons are later revealed.
Video Wills: Initially, Kurou's message to Arata was to explain why he divorced his mother, but it turns into this when he receives his Dead End at the end of the recording.
Tohru Kibe
The CEO of Chronus Seed Corporation which developed the Future Diaries. His goals are ambiguous but it seems he wishes to make a better future.
Affably Evil: He believes the deaths of the diary owners are worthy sacrifices to make the future better.
A God I Am: Averted. Kinjiro believes he is Deus, but it turns out he is a diary owner and hates Deus.
