Future Diary

""What are you scheming?" "An interesting game.""

Mirai Nikki (literally Future Diary) is a dark Manga about the asocial Yukiteru Amano, who obsessively keeps journals. One day, he finds that his imaginary friend Deus Ex Machina, the lord of time and space, has made his cell phone diary able to predict the future. After getting over the initial shock of having a supernatural cell phone, Yuki enjoys his new-found powers until he comes across a diary entry stating his exact time of death...

After taking out his would-be murderer, Yuki is invited to a gathering with ten other people, where Deus explains that they are now in a Battle Royale for the position of God. Some of the diary holders have personal reasons to claim the throne; others are psychotically insane. And soon enough, young Yuki finds himself without any true friends or allies aside from the curiously Yuki-obsessed participant, Yuno Gasai...

The common traits of all twelve diaries are as follows:


 * All diaries predict the future. Each diary does so in a different fashion, based on how the owner used it before they were selected.
 * Each owner is assigned a number from 1 to 12, and until their identity is discovered by the other owners, is only referred to by that number, Yukiteru, for example, being called the '1st.'
 * The diaries can take any shape or form, but the most common by far are cellphones.
 * Should a diary owner do something differently or influence events so that the results turn out differently from a diary prediction, the diary changes accordingly. In short, the futures set by the diaries are not set in stone.
 * Most importantly, a diary is its holder's future. If it is damaged beyond working order by whatever or whomever, the diary's owner will cease to exist.

Mirai Nikki also has two spin-off manga. The first is Mirai Nikki: Mosaics, focusing on the ninth diary holder Minene Uryu and expounding on several of the minor characters. The second is an Alternate Timeline spin-off, Mirai Nikki: Paradox, in which Aru Akise replaces Yuki as the main character.

The manga was licensed by Tokyopop, and released in the United States as Future Diary; 10 of its 12 volumes were released before the US branch of the company went under. An animated adaptation aired between October 2011 and April 2012 with a pilot OVA released beforehand.

A new live action drama called Mirai Nikki: Another World began airing in Japan on April 1st, based in alternate world featuring a familiar plot but with a new cast of characters. Most are expies of the original characters with some differences. Arata Hoshino takes Yuki's place, a Lazy Bum of a college student who has no interest in his future. That is until he receives a limited release cell phone from his friend Rui Moriguchi which happens to have the Future Diary's powers. Now stuck in his own survival game, with his own version of Yuno for company.

Compare and contrast Death Note, which also features a "notebook" as a centerpiece. Also compare and contrast "Kamen Rider Ryuki" which also features a "There Can Be Only One" style royale amongst 13 individuals. See also Devil Survivor, for the counterpart "Laplace Mail".

Definitely not to be confused with Yume Nikki.

Character sheet for this series is now open for business.

"Hinata: He doesn't want it! Yuno: Nah, he's pleased with it."
 * The Abridged Series: by the guy who brought you the Higurashi Parody Fandub, found here.
 * Absurdly Sharp Blade: Yuno is typically armed with a variety of kitchen implements, but the damage she does with them is out of this world.
 * Abusive Parents:.
 * Akashic Records: One of the tools used by Deus.
 * All Deaths Final: However, this can still be worked around.
 * All There Is to Know About "The Crying Game": Actually an in-universe example: since the diaries all give the DEAD END of the user, it forces the user to change tactics in order to avoid it. However, there are unwritten portions that are found within the diary, and, when given the option, the user can take that hidden option, such as when Yukiteru decides to  and even surprises Deus.
 * Alternate Timeline: Paradox. Eventually,
 * It's shown that
 * Note that this is mostly because
 * American Kirby Is Hardcore: The American release changes the cover of the volumes from white to black, adds a skull to the title, and throws in the tagline "Every Text Could Be Your Last".
 * Anti-Hero: Yuki. He starts out as a type 1 but.
 * Anyone Can Die: Given that it is a battle royale for godhood, this is to be expected.
 * Art Evolution
 * Artificial Human:
 * Attempted Rape:
 * Ax Crazy:
 * Yuno, literally.
 * This pretty much sums up the majority of the cast, really.
 * In Chapter 57, there is true form.
 * Babies Ever After: The epilogue depicts
 * Back From the Dead:
 * Badass Normal: Akise Aru manages to outwit a number of journal holders.
 * He definitely earned his title of the strongest Non-Diary holder in his Spin-off, Paradox, where in one fell swoop, he This because he got bored of following Yuki's path, and so decided to Screw Destiny.
 * Later,
 * Barbie Doll Anatomy: Averted in Chapter 52 after being played straight for the rest of the series.
 * Batman Gambit: Given that it's a series about people who can predict the future trying to out manipulate each other, this is bound to show up.
 * Battle Couple: The 7th. Yes, the 7th is two people. gradually become this as well.
 * Beware the Nice Ones
 * Big Bad Duumvirate:.
 * Big Damn Heroes: Yuki pulls this off early on against.
 * In Chapter 54.
 * Big Entrance 12th (Yomotsu Hirasaka) does this when introducing himself to the 1st, 2nd, and Sixth in a manner that imitates the Power Rangers thanks to giant explosions going off in the background, a derranged entrance speech, and a five man group colored in 5 different colors doing a.
 * Bishonen: Yuki and Akise.
 * Bodyguard Crush: Both Akise and Yuno towards Yuki.
 * Body Horror: If your diary is destroyed, you die in a manner that appears as though a black hole spontaneously generates in your chest. It's much more noticeable in the anime.
 * Book Ends: In the first chapter, when Yuki almost stabs Yuno, she tells him "You didn't stab me, that's not the future." In the final chapter,
 * Bread, Eggs, Milk, Squick: At the end of chapter 23 when Yuki asks Yuno why she can't leave some luggage. She says she can't because of important things like "underwear, towels, meds, and a bunch of other stuff". The "other stuff" is shown to the viewer as.
 * Break the Cutie:
 * A rare male example when it happens to Yuki after . He breaks even further and ends up.
 * Just about any flashback involving.
 * Bullying a Dragon: each plant a "Take That!" Kiss on Yuki to spite the notoriously Ax Crazy Yuno. Neither one survives.
 * Came Back Wrong: The reason why.
 * Cell Phone: Apparently many Japanese keep their diaries on cell phones; a usage not followed elsewhere.
 * Chekhov's Gunman: Remember that Ai girl at Tsubaki's temple? She shows up later
 * Chess Motifs: Only in the beginning, when a DEAD END is compared to a Checkmate. This is why it was such a big deal that Yuki survived; it wasn't meant to be possible.
 * Class Is in Room X-01: Averted. Yukiteru and Yuno are both in class 2-B initially, and they end up in 2-C and 2-D respectively and their new school. While that can still be considered somewhat lazy, it looks like this was a deliberate aversion.
 * Clingy Jealous Girl: Yuno towards Yuki, and Akise towards Yuki in a male version.
 * Crapsack World: God arranges Battles Royale for kicks. The hero is apparently the only nice journal holder. A terrorist who blows up schools is one of the more sympathetic characters.
 * Creepy Child: The 5th diary owner, Reisuke "Let the massacre begin!" Houjou.
 * Cry Cute: Whenever Minene's childhood and her parents' death is brought up, expect the terrorist bomber to at least shed a few tears.
 * Dating Catwoman: Nishijima and Minene in Mosaics, though the criminal is the main character.
 * Dead-Man Switch: Minene rigs one of these up to herself when she holds up the school.
 * Dead Person Impersonation:.
 * Minene does this as well, killing a rookie police officer and taking her place so she could get close to her target
 * Disappeared Dad:
 * Yuki's dad, as his parents are divorced.
 * Hinata's dad is mostly absent from her life due to and disappears altogether when.
 * Does This Remind You of Anything?: When Yuno . It doesn't help that she's in her underwear and sitting on his lap. The following conversation occurs:
 * Does This Remind You of Anything?: When Yuno . It doesn't help that she's in her underwear and sitting on his lap. The following conversation occurs:

"Yukiteru: You said it yourself! The eyes have it! *cue Eye Scream*"
 * The Dulcinea Effect:
 * Yuki is shown to act this way towards Tsubaki, quickly trusting her and wanting to protect her. Granted, some of this is probably due to the fact that she looked to him like a beautiful Damsel in Distress that is one of the few sane people he had seen recently..
 * Akise is shown to act this way towards Yuki in the Alternate Timeline spin-off Paradox. He just met Yuki, yet quickly decides to use Mur Mur's wish she promised him to save Yuki and comes to the conclusion that he's going to fight in Yuki's place, allowing Yuki to become God.
 * Dude in Distress: Yukiteru spends the better portion of an entire issue chained to a wall.
 * Drum Bathing: Near the end, Yukiteru and Yuno take a bath in a oil drum together.
 * Dying Moment of Awesome: See the whole scene here.
 * The anime makes it a bit less awesome but a lot more realistic by.
 * Dysfunction Junction: The whole cast.
 * Earn Your Happy Ending
 * Easily Forgiven: Yuki forgives people a little too easily, especially his crazy girlfriend.
 * Ecchi: The series occasionally delves into this, mostly with Yuno.
 * The End of the World as We Know It: Deus ex Machina threatens this if Yuki doesn't buck up and start killing people.
 * Enfante Terrible: A 4-year-old child with a picture journal comes to kill the main characters.
 * Expy:
 * Yuki shares a number of character traits with Shinji, especially in the beginning. Both are timid and lonely but unable to connect with the people around them even if they really want to and forced to fight even though they really don't want to. Both seem to want their father back in their lives, but both end up betrayed. The main difference seems to be that Yuki has his mother and Yuno, the latter being something of a mixed blessing.
 * Deus himself looks a bit like an Eva in some panels of the manga.
 * Akise is an expy of Kaworu from the same series. The parallel is at the same time taken further than expected with the revelation that, and harshly subverted.
 * Ironically, Akise's voice actor in the anime is the same Kaworu's.
 * Minene can also be considered as an expy of Misato from Evangelion -so that makes a total of 4 expy. Huh.
 * Exty Years From Now
 * Even the Guys Want Him: Yuki, as far as Akise is concerned.
 * Everyone Calls Him "1st": The diary owners are all referred to by the order in which they were given their diaries. Most of the diary holders don't even get any other name most of the time they are mentioned. Particular mention goes to The 10th and The 12th
 * Evil All Along: In chapter 50 Akise claims that
 * Eye Scream: gets a dart through the eye and then receives a cool eyepatch!
 * Gory Discretion Shot: The Anime shows reaching in to pull the eyeball out...
 * Face Heel Turn:  Considering the very nature of the survival game, it would probably be wiser to list the exceptions.
 * The Faceless: Twelfth
 * Fan Service: Primarily of Minene, although Yuno and Tsubaki warrant honorable mentions, though the contexts for those two are disturbing enough to barrel straight through to Fan Disservice territory.
 * Food as Bribe: In the last chapter of Mosaic Akise uses Minene's hunger to get her to compete in a beauty pageant with the incentive that she can use the prize money to buy herself food. He keeps it up by deliberately eating food in front of her as a constant reminder to why she's competing.
 * Four Philosophy Ensemble:
 * The Cynic: Minene
 * The Optimist: Yukiteru
 * The Realist: Yuno
 * The Apathetic: Akise
 * Gainax Ending: The epilogue most certainly counts.
 * Gambit Pileup: Scry vs. Scry meets I Know You Know I Know meets Death Note.
 * Girl with Psycho Weapon
 * A God Am I:
 * Played with - despite all appearances, none of the characters believe themselves to be God or have Godlike powers. They are competing for his position, but each has their own, unique, reason for wanting the position and power, very little to do with their ego. Not to say the reasons are good...
 * however plays it straight.
 * God Is Evil: He may have some damn significant justification, but any God that tells a 4-year-old to kill (semi)-innocent people earns this title.
 * Godiva Hair: Minene
 * Gratuitous English: Akise agrees to give Hinata his diary provided she can guess which hand he's holding a coin in. LEFT OR RIGHT?
 * Grotesque Cute: Particular mention should be given to Yuno, Reisuke, and.
 * Heel Face Turn
 * Heroic BSOD: Yuki suffers a pretty nasty one complete with paranoia fuel,.
 * Hidden Eyes
 * Hope Spot: blows herself up to open an armored door.  It's not all bad though, since.
 * I Did What I Had to Do: An unfortunate byproduct of Yuki's taking a level in badass.
 * I Want My Beloved to Be Happy: Yuno. In later arcs, after Yuki swears to avenge the deaths of his parents, Yuno offers to die for him when the time comes.
 * If It's You It's Okay:
 * In the Alternate Timeline spin-off Paradox, Akise maintains that he isn't gay - he only feels this way about Yuki. This is also Akise's reason to . He states directly to Deus' face that he loves Yuki which is why.
 * In the main storyline there's Mao, who's not-so-secretly in love with Hinata - she can't stop looking at/thinking about/lusting after/recording in a diary Hinata's impressive bust (for a 14-year-old).
 * Improbable Aiming Skills: Yuki and his darts.
 * Infant Immortality: Averted.
 * Ironic Echo: In the manga, Minene outs Yukiteru as The First by reading the look in his eyes when she pieces together the clues leading to his identity. Later on, Yukiteru manages to avoid running on one of her landmines by reading her in the same way.

"Yuno:"
 * Just Hit Him: Double Subverted in chapter 23 of the manga and episode 12 of the anime.
 * Knife Nut: Yuno prefers the ax, but she knows her way around knives too.
 * Yuno wanted to meet Yuki's mother but she was worried that him mom wouldn't like her. So she brought some tools with her just in case, and by tools she meant a duffel bag filled with knives.
 * Lamarck Was Right:.
 * Lonely At the Top:.
 * Lotus Eater Machine:.
 * This was more of a subversion or playing with the idea of a Lotus Eater Machine used as Fridge Horror. While the Machine is utilized,
 * Love At First Sight:
 * Yuno fell in love after her first conversation with him.
 * In Paradox, Akise falls in love with the wounded Yuki at first sight.
 * Love Makes You Crazy/Love Makes You Evil:
 * Yuno. She was sort of crazy/evil already though, given how . It's also likely that were the ones who drove her insane in the first place.
 * Later on Yuki gets a little crazy for Yuno.
 * Mad Bomber: Minene.
 * Mad Love: The only plausible relationship you can have with an utterly Ax Crazy Yandere.
 * Made of Plasticine: People are often sliced completely in two with absurd ease.
 * Manipulative Bastard: Happens with almost Death Note-esque frequency. A particularly disturbing mention must be given to Yuno in Chapter 49. Yuno, on the other line, starts laughing her butt off, while a shot of her diary reveals that Yuki's friends weren't lying. She didn't want them to have him.
 * Master of Disguise
 * Meaningful Name: The kanji for "Gasai" (seen here) means "my wife".
 * Not to mention Juno "the goddess of marrige" which according to the Master Wiki is pronounced "Yuno." Coincidence?
 * The fact that Juno was the most possessively jealous Yandere goddess helps a lot. Also, Yukiteru's own name is a corruption of "Jupiter".
 * Heck, all the diary holders have names that associate them with some Roman god or goddess.
 * A Million Is a Statistic: The conflict between the diary holders has resulted in a total body count that numbers somewhere in the hundreds. Most of the diary holders have no reservations against killing countless innocent bystanders in pursuit of each other, and even the 1st, Yuki, ends up crossing his moral boundaries.
 * Moment Killer: Nothing gets in the way of a like learning that the Big Bad has succeeded in his plan when you thought you'd foiled it.
 * Yuno invariably kills her own moments. Usually by doing something completely insane.
 * Mood Whiplash: The relationship between Yuki and Yuno constantly and abruptly switches between "Aww aren't they such a cute couple" and "What the hell is wrong with that girl?!"
 * Moral Dissonance: In the later chapters, In his defense,
 * Mummies At the Dinner Table: Yuno . Later,
 * Mundane Utility: In the grace period between Yukiteru getting his diary and Deus announcing the game, Yukiteru uses it for things like cheating on a test.
 * Murder the Hypotenuse: Both Yuno and Akise (in "Paradox") are willing to do this and much more in order to keep Yuki for themselves.
 * Mythological Theme Naming: Each of the Diary Holders' names have some connection to a Roman god/goddess (with Minene being connected to two). Most of the gods or goddesses that they're associated with are a part of the Dii Consentes, the twelve gods and goddesses that were held in the highest regard, but we also have John Balks (Bacchus) and Yomotsu Hirasaka (Pluto).
 * Also, the three "main" characters in Mirai Nikki (Yukiteru, Yuno, and Minene) intentionally form the Capitoline Triad (Jupiter, Juno, and Minerva).
 * For reference, the diary holders are associated as follows:
 * Yukiteru -> Jupiter
 * Yuno -> Juno
 * Hiyama -> Vulcan
 * Kurusu -> Mercurius
 * Houjou -> Ceres
 * Kasugano -> Apollo
 * Marco/Ai -> Mars/Venus
 * Kamado -> Vesta
 * Minene -> Minerva (and Neptune)
 * Tsukishima -> Diana
 * Balks -> Bacchus
 * Yomotsu -> Pluto
 * Nay Theist: Minene. Until she became a diary holder she only attacked religious targets, due to losing her parents in a religious struggle as a child. Her attitude comes off as justified, in a Straw Man Has a Point kind of way, when you think about it. Her beliefs are basically that if there is a God, he is unworthy of reverence because he is clearly indifferent to human suffering -- if not outright malevolent. The whole backstory bekind Mirai Nikki is that Deus, who to all practical purposes is God, considers the best solution to the problem " I need to choose a replacement" to be "pick a dozen random psychos and encite them to kill each other until only one survives, and it's A-Okay to kill as many innocent bystanders in the process as you want, too!"
 * Necromantic: Yuki becomes a rare protagonist version after die. He decides to win the game to bring them back to life.
 * Nobody Poops: Subverted in that Yuno mentions taking care of Yuki's "potty breaks" and she later has to pee in a corner in front of Yuki while they are hiding out.
 * Non-Action Guy: Until he Took a Level In Badass, Yuki didn't do much fighting. Yuno was usually the one to kill their enemies
 * Off with His Head:
 * Official Couple: Yukiteru/Yuno, Marco/Ai,, & a bit surprisingly,
 * Only Sane Man:
 * Yuki starts off as this, but then loses it.
 * The 8th is relatively sane. She doesn't have the will to kill.
 * OVA: The manga was given an 8-minute one in September 2010 that rapidly covers the first several chapters.
 * The Plan: In a series about dueling future readers with magical diaries, you need to do this to get anything done. Thankfully, due to the... unstable nature of the future(With up to 12 people actively changing and screwing with it), there are no plans which are durable enough to get to the Roulette stage of gambitting.
 * Plot Induced Stupidity: Without this, the plot would be stupifyingly complicated. As it is, though, the main character often only checks his diary just before or after an event. Even though it is initially described as being able to see 90 days into the future, it is very rare for anyone to even bother to read more than a little bit ahead. Vaguely justified in that the future is constantly changing whenever any of the diary holders does anything at all while knowing the future, so anything more than the immediate future would be pretty useless.
 * Please Dump Me: Chapter 56 has doing everything she can to get  to hate her.
 * Poisonous Friend: Yuno is about as poisonous a friend as her body's volume of plutonium.
 * Pre-Climax Climax:.
 * Protagonist-Centered Morality
 * Quit Your Whining: Kousaka.
 * Rape as Backstory: . Also
 * Reality Writing Book: Mirai Nikki features journals which contain the future entries of characters, allowing them to see what they'll experience in the future, and react to them. The journals change as they do things. Most of these journals take the form of diaries entered into cellphones, though one woman has hers on a scroll.
 * "The Reason You Suck" Speech: Mar gives Yukiteru a healthy dose of this during every encounter they have. He says that Yukkii and Yuno will never beat him and Ai simply because Yukkii is a coward that let's Yuno fight all of his battles and never gets his own hands dirty. This occurs the first time after they haveki just knocked Yuno down and right before Mar throws Yuki from a balcony.
 * Even after Yukkii tries to change his ways, he is still given one of these in the form of a"The Reason We Suck Speech" by Yuno in chapter 57 as she tells Yukkii the reality of their relationship
 * Even after Yukkii tries to change his ways, he is still given one of these in the form of a"The Reason We Suck Speech" by Yuno in chapter 57 as she tells Yukkii the reality of their relationship


 * Which would make both Yukkii and Yuno a case of
 * Redemption Equals Death:
 * Red Shirt: The policemen.
 * Sadistic Choice: In Chapter 55,.
 * Sakurami Is The Center Of The Universe: Justified -- Deus Did It.
 * Screw Destiny: These are people with future-predicting diaries fighting to become a god. Of course this is going to happen.
 * Scry vs. Scry: The entire premise.
 * Self-Made Orphan:
 * Shades of Conflict: A combination of Black and Gray Morality And Evil Versus Evil
 * Shipper on Deck: Yuki's mom seems absolutely intent on getting Yuno "closer" to her son. Chalk it up to values dissonance.
 * Single-Target Sexuality: Yuno's crush with Yuki. Also Akise, both in the spinoff Paradox as well as in the MAIN storyline.
 * Sliding Scale of Comedy and Horror: Yuno's Yandere behavior can be this at times, especially when combined with Yuki's facial reactions.
 * Spell My Name with an "S": Yuno's nickname for Yuki should be written as "Yukkii" if you go off the katakana for it, though Tokyopop writes it as "Yuki" instead. Most scanlations stick to the former.
 * More notably, the Eleventh's name is romanized as John Balks in most of the scanlations, but Tokyopop romanizes it as John Bacchus.
 * That cute little girl in the Causality Hall, ムルムル? Most translations and webpages romanize it as "Muru Muru" or "Murumuru", but the opening for the series reads clearly "Mur mur" (in two lines) in the background behind her. Any relation?.
 * Spanner in the Works:
 * Stalker with a Crush: Yuno. In one of the more disturbing chapters, right after the hero and audience think she's not so bad, the girl . Of course, this is after we learn that.
 * Stab the Scorpion: Happens a ridiculous amount of times in the series.
 * One chapter ends with Yuki looking as if he's going to abandon Yuno when Akise reveals that . Next chapter reveals that he let go of her hand so that he could push to the ground to avoid gunfire from the 11th Diary Holder.
 * Subverted later in the twin towers when points her gun at Yuki. Turns out there was just a mook behind him. She then explains that she will kill him if the plan fails and nearly does. Ends up truly being Double Dubverted once she doesn't go through with shooting him and instead helps him to reach 11th.
 * Stalking Is Love:
 * This series loves playing ping-pong with this trope. The current status of it seems to be "Stalking is love, but only because ."
 * In chapter 57, Yuki states that he fell in love with Yuno because "she was always by his side."
 * Suicide Pact:
 * Superpower Lottery: The Future Diaries. There are vast differences in their ability to predict, each with its own weaknesses.
 * The 1st's is one of the strongest but still has the weakness that it doesn't predict his own actions.
 * On the other hand, The 2nd has the weakest diary, only predicting one person's actions.
 * Then there is The 5th who can only.
 * The 4th's can only predict crime cases.
 * Let's not even get into the 8th's Diary and what it does.
 * The undeniable winner of the lottery is.
 * "Take That!" Kiss: plants one of these on Yuki when she thinks she's defeated him and Yuno. Unfortunately for her, Yuno doesn't like that one bit.
 * Taking the Bullet: If both of them had survived,  Tear drops...
 * Taking You with Me:
 * Subverted in the fact that
 * Talking Is a Free Action: Oh, so much. "Yuki! There's a mine 1 meter in front of you! Go to the left!" Doesn't sound ridiculous, until you realize that he's sprinting forward, and Yuno's shouting directions to him. And it's commented that he's a good runner, too.
 * The anime makes this more believable: "Yukki! To the left! ... Now the right!"
 * Texting is also a free action. Most of the diary holders have lightning-fast thumbs.
 * Tears of Fear: Yuki, especially in the beginning.
 * Their First Time:
 * There Are No Adults: Vastly averted. Although the two main characters are school age, others are not, and the school-aged kids' parents end up central to the plot.
 * There Are No Therapists: Considering most of, if not all the characters, can be classified as mentally unstable if not out right insane you think half the cast would be in an asylum by now.
 * There Can Be Only One: God has apparently decided that if, he might as well see people fight to the death first. And what better way to chose a successor?
 * Together in Death: averts this.
 * Too Dumb to Live: Tsubaki, did you just
 * Too Soon: Tokyopop changed the name of the Twin Towers to "The Double Tower Building" in volume 9..
 * Took a Level In Badass: After Yuki retaliated against his would-be assassins.
 * Yuno takes a level during the fight with the 7th, when.
 * Tsundere: Mur Mur pegs Minene as one as she watches the Dating Catwoman antics between her and Nishijima. While Minene insists that she's not going to follow some "shojo manga formula", she can't seem to shake Nishijima off of her, culminating with.
 * Unusually Uninteresting Sight: The 8th. She is a gigantic, Pillsbury Doughboy-like woman roughly three times the size of the children she takes care of. No one seems to notice this, beyond a one-shot joke.
 * Villain Protagonist: Oh, and how. The female lead would kill anyone,.
 * Well-Intentioned Extremist
 * What the Hell, Hero?:
 * Yuki calls Yuno on her claim that she and tried to kill his friends because she loved him.
 * In Chapter 50, Kousaka calls out rather than face the Awful Truth they were trying to tell him. He is later called out on this again, this time by . This time it sinks in.
 * Why Can't I Hate You?:
 * Chapter 56 has an inversion..
 * Played straight
 * World of Cardboard Speech:.
 * Yandere: Yuno isn't just an example, she's the queen.
 * You Are Number Six
 * You Don't Want to Die a Virgin, Do You?:, who are both virgins before Chapter 52.
 * Your Days Are Numbered:.
 * Your Princess Is in Another Castle: Chapter 54 comes across as an epilogue, until the last two pages in which
 * You Are Number Six
 * You Don't Want to Die a Virgin, Do You?:, who are both virgins before Chapter 52.
 * Your Days Are Numbered:.
 * Your Princess Is in Another Castle: Chapter 54 comes across as an epilogue, until the last two pages in which

The anime features the following tropes:

 * Action Prologue: Kinda. "Horror Prologue" would be more accurate.
 * Adaptation Expansion: The anime has been adding in scenes from Mosaic.
 * The 3rd also got a bit more screentime to better illustrate his presence in the first episode.
 * It's also been eliminating a lot of the Fridge Logic from the original manga (Such as averting the Talking Is a Free Action described above) and adding content between scenes from the manga (such as Yukiteru's futile attempts to inform Kurusu about the dead bodies in Yuno's house.)
 * More of the eliminated Fridge Logic also includes changing a room filling up with concrete into a room filling with gas.
 * The anime also expands on
 * All There in the Manual: Mur Mur's extra segments.
 * Altum Videtur: The opening features a rapid firing-off of Roman gods' names.
 * Fridge Brilliance: They are the names of the Dii Consentes, the twelve Roman gods and goddesses that were considered to be the highest deities, just toss in Bacchus and replace Neptune with Pluto (or not, since Minene Uryuu also references Neptune). Each of the diary holders is named/associated with one of the gods, so by being participants in Deus' game, they are already considered potential gods!
 * Amazingly Embarrassing Parents: A new scene is added with Yukiteru's mom bonding with Yuno over naked baby pictures.
 * Art Shift: Weirdly done with some Medium Blending at the end of episode five in Mur Mur's ending segment with the 12th; the art is suddenly some crudely made clay figures in stop-motion, with some slightly bizarre 2D animation spliced in between.
 * Bland-Name Product: Kousaka's phone, which is shaped like and obviously is an iPhone, is apparently an iBone.
 * In a scene where Yuki is buying drinks, he attempts to get some Dr. Papper.
 * Censor Shadow: A fairly obvious one once Yuno starts smashing heads in the fourth episode.
 * There's also censor steam in episode 20 when Minene showers.
 * Conspicuous CG: So far, a two-second appearance in the opening credits is pretty much the only time Deus has used hand-drawn art. There are some bits of architecture and a few objects in the opening credits as well.
 * The ferris wheel scene in episode 3 switches jarringly from CGI to traditional animation depending on whether the audience is viewing the car from the outside or inside.
 * 10th's dogs are CG in several shots.
 * Episode 19 also has CG cars.
 * Death Is Cheap: The Stinger for the first episode has Mur Mur attempt to deliver the 3rd's diary, only for him to err on the side of caution and destroy a phone that seems to be monitoring his criminal activites in painstaking detail before she can properly explain the natures of the diary or the game. This happens several times and she rewinds time to reverse his death every time.
 * Depending on the Artist: The anime features a noticeable different artstyle than the manga's, the characters look slightly older than their manga counterparts, also many expressions taken directly from the manga are more extreme: Yuno's shots in particular got a tad more lustful towards Yukiteru, and crazier towards everyone else.
 * Early-Bird Cameo: The anime shows The Third carrying out one of his murders and teaching Yuki and Yuno's class before the point at which he was originally introduced in the manga. Minene also shows up early.
 * Gainaxing: There's a lot of attention paid to Yuno's chest in Episode 3.
 * Gratuitous English: Pretty much all of the second opening is this.
 * Gratuitous German: The opening song's chorus has "Ein, zwei, drei".
 * Idiosyncratic Episode Naming: Disregarding the first few episodes, the episode titles all seem to be related to the natures of the different diaries--so generally cell phone-themed, but "Handwritten Input" for the 6th and "Voice Memo" for the 12th also appear.
 * If Jesus, Then Aliens: When Mur Mur tells Reisuke that he's been chosen for a Future Diary, Reisuke says to her "If there's a God, it's not strange for there to be aliens, right?" and refuses to participate in the game until she shows him an alien.
 * Lethal Chef: In the first Stinger of the anime not taken from the manga, Murmur manages to send Yukiteru and his mother to the hospital with her miso soup. However presumably not everything she makes is poison. In a different stinger she made Yuki corn and he suffered no apparent ill effects.
 * Magical Security Cam: Justified in that it's employed by the universe's god. The bigger mystery is why he's watching Yukiteru sitting on the toilet.
 * Meet Cute: Minene and Nishijima in the tenth episode in the anime version, which only vaguely alludes to their true first meeting.
 * Nobody Poops: Averted even earlier than the manga; both Yukiteru and Minene are shown using the toilet.
 * Ominous Latin Chanting: There is a little in the OVA ending music. It's also applied liberally to the series' opening song.
 * Pixellation: Used to censor any outstanding examples of gore.
 * The DVD/Blu-Ray releases, however, remove this. It's not pretty.
 * Smurfette Principle:  there is only one female - who wears pink.
 * She also happens to be the most muscularly built, for some odd reason.
 * Spit Trail Kiss: 's Forceful Kiss got upgraded to this just for extra levels of Squick.
 * Spoiler Opening: And how! Luckily, at the same time it's also very vague; it's (almost) all stuff you'd have to already know about for it to seem significant.
 * The second opening is also very much a Spoiler Opening, but for a slightly different reason:
 * The Stinger: Comedic sketches and bits of trivia not shown in the show proper close episodes of the anime.
 * Surreal Theme Tune
 * Tears of Blood: The first visual of the opening credits.

The live action drama features the following tropes

 * A God I Am: Deus.
 * Alternate Universe: Hence the title.
 * All Deaths Final
 * Ax Crazy: The new Yuno, although not as much as her other self. That could change, though.
 * Clingy Jealous Girl: Yuno.
 * Expy: Most of the characters are expies of the manga cast, most notably Yuno is pretty much the same characters minus the pink hair and now nineteen.
 * Averted in Arata's case. He is meant to be like Yuki, but actually has friends, is very apathetic, takes a surprising interest in Yuno and takes a stand against the serial killer.
 * Heroic Sacrifice:
 * Lazy Bum: Arata.
 * Love Makes You Crazy: Episode 2 has shown Yuno has these traits, forcing Arata to tie her up temporarily.
 * Stalker with a Crush: Yuno, as expected.
 * There Can Only Be One: It has not been said how many diary holders there are in the drama but the rule still stands that the last person standing shall be the winner.
 * You Don't Look Like You: Deus appears in the show as a talking, purple, sun-shaped emoticon. Although this may be a mere representation since he is God.
 * Zettai Ryouiki: Rui's sister.
