Irisu Kyouko

The player character, a mentally ill university student.

  • Addled Addict: She's addicted to a cough medicine that she eats by the packet, and while she was already completely nuts, the medicine doesn't do her any favours.
  • Animal Motifs: Irisu loves rabbits, felt deeply connected to the class rabbit, and wears a pair of bunny ears as part of her outfit.

  • Be Careful What You Wish For: She wanted Uuji to love her. He did, in a manner of speaking.
  • Becoming the Mask: If Irisu's insanity is beaten back enough, she develops real affection for Ageha and Edo.
  • Berserk Button: She hates cats.
  • Big Bad: Subverted; it’s Uuji who is manipulating her.
  • The Chessmaster: When she needs to be. She alone convinced everyone to go on the trip, so subtly that only Uuji noticed that was her plan all along.
  • Combat Pragmatist: When you're an asthmatic drug addict, you take what victories you can get.
  • Commonality Connection: With Uuji, because they were both always alone.
  • Determinator: Presumably the reason that she can manipulate people despite being pathologically afraid and ignorant of social interaction.
  • Deathbringer the Adorable: You would not expect a girl with fluffy white hair and big anime eyes to be a murderer, but Irisu has always defied convention.

  • Evil Cannot Comprehend Good: Irisu does not understand why she sabotages her own plot during her brief periods of sanity.
  • Love Makes You Crazy: Irisu's mind wasn't in a good place before she fell for Uuji, but at least she wasn't going around killing people.
  • Longing Look: Often directed these at Uuji in class. She was totally content with their 'relationship' never progressing beyond this.
  • Maybe Magic, Maybe Mundane: Sometimes, her eyes glow.
  • Mood-Swinger: She's either passive as wallpaper or in total 'I-will-kill-you-bitch!' Tranquil Fury. There is no middle ground.
  • Only Friend: Uu-tarou the bunny was hers. She was really screwed up by his death.
  • The Quiet One: Never speaks if she can help it. Even her murders are carried out in complete silence.
  • Rousseau Was Right: There is a tiny part of her that doesn't want to hurt anyone, though it is often buried by madness. She would not play the game if she weren't trying to strengthen this part.
  • Advertisement:
  • Shrinking Violet: In her saner moments.
  • Spock Speak: Her written instructions for the camp are formal and use unnecessarily technical words.
    In the hopes that you don’t show unnatural behavior, I earnestly thank you.
    Please appropriately make up some ghost stories.
  • Sure, Let's Go with That: In the best ending, she decides to let everyone live even though that wasn't her original plan.
    Well, this is also fine.

Uujima Satoshi

  • Accomplice by Inaction: Not only is he fine with Irisu murdering Edogawa and Ageha, he wants her to kill him as well!
  • Becoming the Mask: He himself was surprised that he accepted Edo and Ageha's friendship.
  • Beneath Notice: Around people, he likes to act blandly agreeable.
  • Big Bad: He manipulates Irisu into trying to kill Edogawa and Ageha.
  • Birds of a Feather: He both recognizes and accepts Irisu' him, even though she's never mentioned it to him and is batshit crazy. They're just on the same wavelength like that.
  • Cannot Spit It Out: He claims that the reason he didn't speak to Irisu during their childhood was that he didn't want to worsen her asthma, then immediately admits that he was just lying to himself. In reality, he was just too shy to approach her.
  • Conditioned to Accept Horror: He never talks about his own life, but his lack of surprise upon finding out that someone he knows is a murderer says quite a bit.
  • Dark Secret: He self-harms repeatedly and keeps his scars hidden so others won't comment on them.
  • Death Seeker: Again, he wants Irisu to kill him.
  • Every Scar Has a Story: He remarks ambiguously that the bruises on his arms 'memorialize' Uu-tarou. This implies that they are self-inflicted.
  • Love Hurts: All Uuji could think of when Irisu befriended Uu-tarou was how sad she would be when it died. By the time he's in university, his belief that love and pain are inextricably connected has morphed into a fetish.
  • Love Makes You Stupid: Even as he wonders whether Edo and Age would accept his scars, he claims they would be stupid to do so.
    Would they treat me the same way as they've always done?
    They probably would. Because they're idiots.
  • In Love with Your Carnage: He thinks it would be "romantic" if Irisu killed him and then herself.
  • Mad Artist: He only draws a very specific, morbid subject: cat corpses. Naturally, the subject reflects an incident in his Dark and Troubled Past.
  • Mind Screwdriver: The story is Irisu's, but it doesn't make a lick of sense without Uuji's exposition.
  • Shipper with an Agenda: He ships Ageha with Edo not because he cares about either's happiness, but because he finds Ageha's flirting annoying.
  • Social Services Does Not Exist: It is unclear if Uuji even has a family — he never mentions one.
  • Tsundere: One reason he inflames Irisu's psychotic rage is to make her interact with him.
  • Unreliable Narrator: In one diary entry, he claims that he doesn't care about Ageha and Edo mocking him, and in the next, he mentions having an argument with Edo over it.

Age Hatori

A girl whose love for Uuji makes her the target of Irisu's anger.

  • Animal Motifs: Uuji and Irisu both liken her to a cat.
  • Defiant to the End: She really lets Irisu have it as the latter is ambushing her. Except sometimes it isn't 'the end', and Irisu was just playing a prank. Oops.
  • Doom Magnet: What are the odds that two crazed killers would want the same girl dead?
  • Heel Realization: She and Edo used to say "mean things" about Uuji, but after he helped her out when she was sick, they became determined to befriend him.
  • Loving a Shadow: She knows nothing of Uuji's true nature.
  • Nice Girl: She readily accepts Irisu into her circle of friends, despite her misgivings about Irisu invading Uuji's privacy.
    But really, though she has some strange points, she's not a bad girl.
    She's always coughing and her throat seems bad, so I can't help but worry about her.
  • Oblivious to Love: To Edo's love specifically, even though they've known each other for years.
  • Unwitting Instigator of Doom: She dies without knowing why Irisu killed her.

Edogawa Takeru

  • The Generic Guy: He basically exists only so the other characters can play off of him.
  • Heel Realization: Edo and Ageha used to say "mean things" about Uuji, but after he helped Ageha out when she was sick, they became determined to befriend him.
  • Horrible Judge of Character: Makes friends with both Irisu and Uuji without realising that both of them dislike him and think of him as an idiot.
  • Kick the Dog: He is not related to the love triangle, but Irisu and Uuji want him dead anyway, because they're just bastards like that.


How well does it match the trope?
