Who's there? You aren't Yukki! What do you want? Tropes? You...you're here to learn about Yukki, aren't you?! You're trying to gather information for the other Diary Holders so they can kill him! Well, too bad! You won't get a word out of me! I bet if I check my Future Diary, it will say that you're going to try and hurt him, but I won't let that happen!

Wait...what's this? It says that Yukki's going to be fine. No one's going to hurt him? Does that mean...that you aren't here to hurt him? But why would you be here, if not for him? What?! You want to know about me? But why? Why would someone like you care about me? I have nothing to offer someone like you. Still, if I keep you busy, you might get distracted, and you'll forget about Yukki...Alright, fine! If you insist, I'll tell you about myself, but let's make one thing very clear: You will not so much as lay a finger on my Yukki. Ever. If you promise to stay away from him, I'll humor you for a while.

Got it? Stay away from him. I'll be watching...

(By the way, you might already be familiar with the Survival Game, but if not, I'll tell you; if you want to experience it for yourself first, you probably want to stay away. If you do, though, keep your eyes off Yukki!)

My name is Yuno Gasai, but I also go by the alias "2nd." Each of us Future Diary Holders has a number from 1st (that's Yukki!) to 12th. We were chosen by the God of Time and Space, Deus ex Machina, to participate in a Survival Game to the death. The winner was supposed to become the new god. Most of us Diary Holders had some kind of issue involving our past. For me, it was my parents. My father was a good man, but he worked too much, so he wasn't around. My mother, on the other hand...Let's just say she wasn't mentally stable. She locked me up in a cage for the slightest disobedience! One day, when my dad was home, I decided I'd had enough, so I locked them up in the cage to give them a taste of their own medicine. Did I kill them on purpose? Not really, but they ended up dying in there. As you can tell, my life was a mess. That is, until I met the love of my life, Yukiteru Amano! He went to my school, and one day, when I worked up the courage to talk to him, I promised that I would marry him some day.

The first time we played the Survival Game, Yukki and I were the last two remaining. Neither of us could live without each other, so we killed ourselves...or at least that was the plan. You see, Deus was dying, and if there was no replacement, the universe would be destroyed, so we couldn't go on if neither of us won. But then I had a great idea, why not just become God and bring Yukki back to life? So I let him die, and tried to resurrect him. Emphasis on tried. To my shock and horror, I was only able to bring his body back. Then my assistant, Murumuru, who is bound to serve that world's God, came up with a great idea: travel back and time and kill my past self, then live in that world!

I did what she said, but I had to play the Survival Game again. My memories were sealed away to prevent that world's Deus from noticing, but they slowly returned. At the end of the game, Yukki and I were the only ones left again...or so I thought. Turns out one of the other Diary Holders, 9th, actually survived. When Yukki refused to kill me, I decided to head into another timeline, but Yukki tried to stop me from killing my past self again. Eventually, he showed me that he truly loved me, so I killed myself to let my love become God.

Thanks to Yukki's efforts, my dad in the third timeline found me and my mom. After realizing what she was doing to me, he stayed home more often, so I had a more normal upbringing for the next two years. Still, something didn't feel right. I knew I was missing something, but I didn't know what. Eventually I found my other self's Murumuru, who had her memories. I took them back and remembered everything! Through the Power of Love, I was able to find my Yukki, who was still a god. Deus made both of us the new gods of the Third World, and now we live happily ever after!

Now that you know my story, you probably want to hear my tropes now, don't you? All right, as long as you stay away from Yukki... and you don't ask about why I'm acting like my other self when I just have her memories. People just seem to remember that about me more, so I'm trying to think like her here.


  • Abduction Is Love: Yukki wasn't happy about it, but I only kidnapped him for his own safety! Those other Diary Holders were out to get him!
  • Absurdly Sharp Blade: It can be a blade, knife, scissors, anything! I don't care, as long as it keeps Yukki safe!
  • Accidental Murder:
    • I didn't mean to kill my parents! I just wanted to teach them a lesson, but I accidentally left them in that cage for too long.
    • First World Yukki died because of me, but please believe me when I say I didn't mean to kill him for good. I thought I could resurrect him after I became God, but it didn't work.
  • Action Girlfriend: I'm Yukki's girlfriend before anything else. I'm also willing to do anything to protect him.
  • Aggressive Submissive: When Yukki's in danger, I can come off as aggressive, but I tend to get shy during more intimate moments.
  • The All-Solving Hammer:
    • If Yukki's in danger, the answer is simple: just use a weapon, and the threat will disappear!
    • Also, I used a hammer to reach my Yukki after he became God.
  • All Take and No Give: Some people say this about me, but I know Yukki loves me too.
  • Alternate Self: In the First World, I won the Survival Game and went back in time to kill myself in the Second World. My First World self died, but I got those memories back in the Third World.
  • Always Save The Boy: This is the only thing that really matters to me. Who needs anyone else when I can have Yukki?
  • Anti-Villain: Apparently some people think I'm evil for loving Yukki. Well, at least they can sympathize with my situation even if they don't agree with my methods.
  • Ascend to a Higher Plane of Existence: I became God because I thought I could resurrect the dead, but I found out the hard way that it doesn't work.
  • Attractiveness Isolation: I was really popular with boys at school, but of course I didn't care about any of them except for Yukki.
  • Ax-Crazy: Some people might call me crazy, but I'm just in love!
  • Badass Adorable: I'm a competent fighter, and I'd like to think Yukki finds me adorable.

  • Badass Long Robe: When I told Yukki that I already became God before, I used this robe to highlight my authority.
  • The Baroness: Some people might call me one, but I'm not evil! I just wanted to protect Yukki!
  • Battle Couple: I'll admit, Yukki was more prone to letting me protect him at first, but over time he got better at fighting.
  • Because You Were Nice to Me: Yukki was the only person who was ever nice to me. That's why I latched on to him for emotional support. I even admitted this during the final battle, but since then I'd like to think my feelings became genuine.
  • Being Tortured Makes You Evil: I was certainly tortured, but I don't take kindly to being called evil.
  • Big Bad Friend: Big Bad Friend? You think Yukki and I are just friends?! What are you trying to imply?!
  • Body Backup Drive: Murumuru implanted my First World self's memories into my Third World self, creating the version of me you see today.
  • Bodyguard Crush: I acted as Yukki's bodyguard during the Survival Game, but crush is a bit of an understatement.
  • Break His Heart to Save Him: Yukki couldn't bring himself to kill me, so I tried to convince him that he should become God, but in the end I had to do it myself.
  • Broken Ace: I try to do everything for Yukki, but I admit that my past is rather dark.
  • Broken Bird: The way my parents treated me in the First World changed me, but I'm glad; it gave me the survival skills necessary to protect Yukki!
  • Cassandra Truth: I knew 6th was just trying to trick Yukki, but he wouldn't listen! All because I had a few corpses in my house...
  • Charles Atlas Superpower: I didn't have any supernatural powers aside from my Future Diary (at least prior to becoming God), but I was still a pretty good fighter even then.
  • Clingy Jealous Girl: No one is allowed to get close to Yukki! He belongs to me! (Except his mom, she's pretty cool.)
  • Clothing Damage: 6th tried to have her followers unclothe and rape me, but Yukki stopped them before it was too late!
  • The Corrupter: Yukki needed to learn how to fight, so I helped nudge him in the right direction, especially after his dad died. I don't see what's so corrupt about that.

  • Creepy Child: Creepy? How dare you! I just love Yukki, that's all.
  • Creepy Monotone: I guess my voice intonation could use some work...
  • Curtains Match the Window: My eyes and hair are the same color.
  • Custom Uniform: I wore a uniform, even when no one else did. I hope Yukki found it cute!
  • Cute and Psycho: I think Yukki finds me cute, but I hope he doesn't still think of me as a psychopath!
  • Cute Bruiser: To anyone who tries to hurt Yukki!
  • Dark Action Girl: I had to get my hands dirty to protect Yukki.
  • Dead Person Impersonation: I posed as my Second World self, hoping that Yukki wouldn't notice. Aru Akise got in the way of that...
  • Death Seeker: I was consumed by guilt at the death of First World Yukki. After all the other Diary Holders were dead, I tried to get him to kill me, but he refused, so I had to do it myself.
  • Declaration of Protection: For Yukki, of course!
  • Despair Event Horizon: This is how I felt after I realized you can't bring the dead back to life. Poor First World Yukki...

  • Died in Your Arms Tonight: This is how my First World self died.
  • Dissonant Serenity: I always manage to maintain a smile, as long as Yukki is safe!
  • The Dog Bites Back: I couldn't take my parents' abuse and neglect anymore! I had to show them what they were putting me through.
  • Doppelgänger Replacement Love Interest: Second World Yukki first fell in love with my First World Self, but now I'm from the Third World, albeit with memories of my First World self.
  • Driven to Suicide: After I realized that I couldn't bring myself to kill Second World Yukki, this is what I felt.
  • Dull Eyes of Unhappiness: I knew that 4th couldn't be trusted! When I tried to find a weapon, I might've flashed this face.
  • Earn Your Happy Ending: It took three different universes and thousands of years, but I finally reunited with Yukki and we'll be together forever and ever! And we've both become gods, so not even death will part us!

  • Elevator Snare: This is how I kissed Second World Yukki for the first time!
  • Engaging Conversation: I told Yukki that I wanted to become his bride back then. He knew I wasn't joking, right...?
  • Evil Laugh: Hinata was always trying to steal Yukki from me, so I couldn't help but laugh when he finally realized how dangerous she was and killed her.
  • Evil Orphan: You think I'm the evil orphan? Look at 8th's children. They tried to hurt Yukki! (OK, maybe we attacked them first, but still.)
  • Evil Sounds Deep: My voice is usually pretty high-pitched, but it can drop when I'm upset.
  • Face of an Angel, Mind of a Demon: I was influenced by Murmur, so I guess you could say I had the mind of a demon.
  • Faux Affably Evil: I pretended to be nice to people at school just so they would leave me alone. Of course, I didn't really care about any of them.
  • Feminine Women Can Cook: I knew that Yukki's mom would be impressed if she knew I can cook! Of course, I had plenty of time to learn after my parents died.
  • First-Name Basis: This is especially important in Japanese. I always call him Yukki, but my Second World self called him Amano-kun.
  • Forceful Kiss: When I kissed Second World Yukki for the first time, I was the one to come onto him. To be fair, I already knew him because I came from another timeline.
  • Freudian Excuse: My parents tortured and abused me! I think I deserve a chance at happiness after what I went through.
  • Gas Chamber: I tried to kill Yukki's backstabbing "friends" with one of these, but it didn't work.
  • Girl with Psycho Weapon: I have a lot of weapons. As long as I can protect Yukki, I don't care which ones I use!
  • Girlish Pigtails: I change my hairstyle from time to time to impress Yukki, but sometimes I wear these.
  • Glowing Eyes of Doom: My eyes sometimes glow when I'm concentrating. Maybe it came from my latent god powers?
  • God Couple: With Yukki, of course! Deus made us co-Gods in the 3rd world.
  • God Is Dead: My First World self was this, but now I'm alive and well!
  • God Is Evil: Some people consider me this, but just imagine if one of the other Diary Holders won the Survival Game! That would've been horrible!
  • God Was My Copilot: In the Second World, I did everything in my power to protect Yukki as God of the First World.

  • Go Out with a Smile: When I killed myself, I smiled because I knew Yukki would be happy!
  • Go Through Me: If I have to die for Yukki to live, so be it!

  • Heel Realization: I have to admit, I realize that I might have hurt Yukki, but I was only trying to protect him!
  • Hot Goddess: How dare you! Only Yukki has the right to call me hot.
  • Hyper-Awareness: I knew that rascal 5th was up to no good, so I was extra careful with that poisoned food he tried to feed Yukki.
  • Hypercompetent Sidekick: At the start of the Survival Game, I was much more skilled than Yukki. He's gotten a lot stronger though!
  • I'll Kill You!: What I said to that conniving Akise when he tried to stop me. He got what he deserved!
  • Indifferent Beauty: I know other boys considered me attractive, but I don't care what they think.
  • In Love with Love: I became attached to Yukki for emotional support. He was the only one who truly cared about me, especially after my parents died. Though I didn't want to admit it to myself, I eventually came clean to Yukki that my love wasn't genuine, but I eventually learned what real love is thanks to him.
  • Interrupted Suicide: I tried to get 4th to shoot me, but Murmur got in the way, so I had to stab myself instead.
  • It's All About Me: Not me, but Yukki! OK, maybe I had my own reasons for doing it too...

  • Katanas Are Just Better: I used one during the battle with 11th.
  • Kubrick Stare: I wanted Yukki to know that I still loved him, even though he found out my secret, so I peeked through his mailbox.
  • Lack of Empathy: I didn't really care about anyone else besides Yukki in the First World.
  • Lady Macbeth: I tried to tell Yukki that he needed to be tough if he wanted to survive, but he didn't really listen until his dad died.
  • Last Kiss: Yukki gave me a kiss before my First World self died. Thank goodness it wasn't really a last kiss!
  • Little Miss Almighty: I had the powers of a god, but Murumuru sealed them away in the Second World.
  • Longing Look: I swore to protect Yukki no matter what after the Survival Game began.
  • Love Makes You Crazy: If I'm crazy because I love Yukki, I wouldn't have it any other way!
  • Love Makes You Evil: Some people think of me as evil, but they just don't understand true love.
  • Mad Love: Of course! I'm madly in love with Yukki.
  • The Man in Front of the Man: I had to guide Yukki through the Survival Game myself in order to ensure his survival.
  • Manipulative Bastard: Sometimes you have to be manipulative if your boyfriend won't listen to you!
  • Mask of Sanity: I had to pretend to be normal at school, so the police wouldn't come after me.
  • Memory Gambit: Murumuru sealed my memories away when I went back in time.
  • Mood-Swinger: I tried to be happy the whole time, but it's hard when people are trying to kill Yukki!
  • Murder Is the Best Solution: If someone is trying to hurt the person you love, why should you show them mercy?
  • Murder the Hypotenuse: Those other Diary Holders were just getting in the way. It was a Survival Game after all.

  • Not Good with Rejection: Good thing Yukki will never reject me! Right, Yukki?
  • Obfuscating Stupidity: When the second Survival Game first started, I really didn't remember anything, but I slowly recovered my memories over time. Still, I had to play dumb to avoid attracting the attention of Deus.
  • Official Couple: Yukki and I are a couple, and you'd better not forget it!
  • Offscreen Teleportation: Comes with having control over the time-space continuum.
  • Omnicidal Maniac: Destroying the universe was never my explicit goal, but I was more than willing to do it for Yukki!
  • Only Friend: I wish this was the case, but Yukki keeps associating with Hinata, Mao, Kousaka, and Akise. I wish he would realize the bad influence they are on him.
  • Palm on Cheek Pose: I did this when I swore to protect Yukki.
  • Pants-Free: I'm going to be Yukki's wife someday, so why should I be afraid of him seeing me like this?
  • Parental Neglect: My father really loved me, he truly did, but he was always so busy. It's too bad I didn't realize this until it was too late...
  • Pitbull Dates Puppy: Maybe at first, but Yukki got tougher over time.
  • Pre-Insanity Reveal: I wasn't always a killer (my parents' death was an accident). Blame Deus for throwing us into this Survival Game!
  • Properly Paranoid: Everyone else was out to get Yukki! His classmates betrayed him, his "friends" were working for 10th. I was the only one who saw them for what they really were.

  • Psycho Sidekick: Some people think I would qualify as this, but I was just trying to help Yukki survive.
  • Psycho Supporter: Some people might consider me a psycho girlfriend, but it's the likes of Akise and Hinata that Yukki really needs to worry about!
  • Put the "Laughter" in "Slaughter": I can't help it, I feel pretty good when I see people who were trying to hurt Yukki dying.
  • "The Reason You Suck" Speech: This is when I admitted to Yukki that I didn't really love him. I do now though, so don't forget!
  • Redemption Equals Death: I tried to kill Yukki, but then I wiped the slate clean by sacrificing myself for him.
  • Red Oni, Blue Oni: Yukki can be pretty submissive, in contrast to me, but I wouldn't have it any other way!
  • Relationship Sabotage: I wasn't about to let him fall for that temptress Moe Wakaba! Thankfully they didn't end up together (except in the Third World, but my Yukki is from the Second World).
  • Room Full of Crazy: I tried to stop Yukki from going in there, because that's where my past self's body was, but he found it.
  • Rose-Haired Sweetie: I always act sweet around Yukki!
  • Satellite Love Interest: I exist only to love Yukki, nothing more, and that's how I like it!

  • Stalking is Love: But I did it because I love him! (Well, I do now at least).
  • Star-Crossed Lovers: Even though I died, I somehow not only regained my memories of the First World, but I broke the barrier between dimensions and found Second World Yukki. If that's not proof that we're fated to be together, I don't know what is!
  • The Starscream: In a moment of weakness, I betrayed Yukki, but thankfully I came to my senses before I killed him.
  • Stepford Smiler: My smiles are genuine, but others see it as a mask for insanity.

  • Trauma Conga Line: Can you really blame me for attaching myself to Yukki after everything I went through?
  • Tsundere: I didn't want to admit it, but I really did like Second World Yukki deep down.
