The protagonist, as well as a reluctant attendee at the party. She used to be more cheerful and outgoing until her sister's death.

- A Birthday, Not a Break: Raiko's sister died on August 14, Raiko's birthday.
- Deadpan Snarker: She can often be quite snarky. For example, one dialogue choice about Rie's costume is that she'll be fine "as long as Taiko's a necrophile."
- First-Person Smartass: Her internal narration is quite snarky.
- Introverted Cat Person: She likes cats (albeit not the cat costume her mom bought her), and doesn't have many close friends.
- Jerk with a Heart of Gold: She can be fairly gloomy and sarcastic, but she's a kind enough person that she's willing to jump to Kamen's defense and prove her innocence, despite how Kamen had treated her.
- Luminescent Blush: After being kissed by Kamen in the ending.
- Meganekko: She wears glasses.
- My God, What Have I Done?: Her reaction if she ends up accusing someone innocent in a bad ending.
- My Greatest Failure: It's revealed that she feels responsible for her sister's death.
- Perpetual Frowner: She's almost constantly shown with a bored, disaffected frown.
- Pungeon Master: She likes making a lot of death and zombie-related puns regarding Rie's costume.
- Sour Outside, Sad Inside: She's not the most cheerful person and keeps others at a distance, but inside, she's mourning the loss of her sister, something she blames herself for.
- The Stoic: She's practically emotionless, and Mika struggles to get a rise out of her.
- Used to Be a Sweet Kid: She used to be a friendlier and more open person before her sister died.
- What the Hell, Hero?: She tears into Taiko for jumping to conclusions and suspecting Kamen on the good ending path, and orders him to apologize to her.
Raiko's longtime best friend.
- Affectionate Nickname: Raiko calls her "Bara-chan."

- Nice Girl: She's described as the most compassionate person Raiko knows.
- Super Gullible: She tends to believe stuff fairly easily.
- Tender Tears/Tears of Fear: She breaks down crying in grief over Momoko's death and fear that someone else might be killed soon.
The hostess of the party, as well as the daughter of the owner of Miyamoto Mountain Resort
- All Love Is Unrequited: She has a crush on Taiko, who doesn't appear to notice her feelings.
- Book Dumb: She's not very good in school.
- Cannot Keep a Secret: She ends up spilling the beans about Runa having once been in love with Hiro, after some gentle prodding from Taiko. Her and Runa's conversation about the fake murder prank also gets overheard by Kamen.
- Didn't Think This Through: Played for Laughs. She realizes too late that her disgusting zombie costume with a large amount of fake blood (which is quite uncomfortable for her) isn't the best way to win Taiko over.
- The Ditz: She's described as highly absent-minded and a bit forgetful. Hiro takes advantage of this by claiming that she failed to unlock the bathroom, thus tricking her into giving him the keys so he could unlock the guest room for Momoko.
- Fatal Flaw: She admits that she has difficulty accepting the idea that one of her friends could be a killer, especially Runa.
- Hidden Depths: Despite seeming somewhat scatterbrained, and having an ulterior motive for throwing the party, she is surprisingly considerate of her friends, and does intend for everyone involved to have a good time.
- Secretly Wealthy: Downplayed, but with her down-to-earth attitude, people don't realize that her family is rich.
- Tempting Fate: She declares that her master plan to win Hiro over won't possibly fail.
- Tomboy and Girly Girl: The tomboy to Runa's girly girl.
- Tomboy with a Girly Streak: She's tomboyish by nature, but is interested in hooking up with Taiko.
- Unwitting Instigator of Doom: Her decision to hold the Halloween party, as well as giving Hiro the keys to open the bathroom, gives Momoko the opportunity she needs to set her plan into motion. Her plans for a fake murder prank also helps enable Momoko to convince Hiro, Kamen and Kotoba to play another prank on her, enabling Momoko to carry out her real murder plan.
Rie's best friend.
- Cat Smile: She sometimes adopts one when teasing Rie.
- Death Glare: She gives one to Taiko, not happy about his questioning obviously indicating that he thinks she's a suspect, especially on the grounds that she'd once been in love with Hiro.
- Establishing Character Moment: She teases Rie about making her guests stand outside in the cold, then formally greets Raiko and Nobara.
- Hair of Gold, Heart of Gold: A blonde who's one of the nicer members of the cast.
- Horrible Judge of Character: As a result of her infatuation with Hiro, she doesn't pick up on the warning signs about his true personality.
- Kimono Is Traditional: She's fond of kimonos, and wears one as part of her cosplay, as well as in the good ending. A piece of bonus art shows her wearing one for New Year's Day.
- Last-Name Basis: She refers to the cast by their last names, along with the "-san" honorific.
- Mock Millionaire: Accidentally comes off as this, since people incorrectly assume her family is wealthy. This includes Hiro, whose attraction to her was based on this belief.
- Nice Girl: She's a kind and caring individual. While she's honest enough to admit that she had difficulty getting along with Momoko, she was telling the truth about her desire to befriend her.
- The Ojou: She gives off this impression with her manners, which is why people are surprised to learn that she's actually poor.
- Penny Among Diamonds: Runa's the only member of the group who comes from a poor family. The Miyamoto family is highly wealthy, and while none of the other eight are in the same category, the Shinpuku family owns its own house, which is more expensive in Japan than in the West.
- Red Herring: She's a likely suspect for the murder considering her possible feelings of jealousy toward Momoko, but she's innocent of the crime.
- Rescue Romance: She fell for Hiro after he helped her when she sprained her ankle in a bicycle accident. Unfortunately, his attention turned to Momoko shortly afterward.
- Second Love: In the good ending, she finds another guy she's interested in.
- Spanner in the Works: Because Runa forgot the green wigs, Momoko's plan to impersonate Kamen ended up being hindered.
- Speak Ill of the Dead: While uncomfortable about engaging in this trope, she did mention that there were some "confrontations" between her and Momoko, since the latter was jealous of her. That said, she genuinely wanted to become friends with Momoko.
- Tomboy and Girly Girl: The girly girl to Rie's tomboy.
- True Blue Femininity: Apart from her costume for the party, she wears blue kimonos in the ending and in a CG for "New Year's Runa."
- Unwitting Instigator of Doom: Her insistence on inviting Hiro and Momoko despite her issues with them, as well as agreeing to the matching cosplay with Momoko, helped lead to their murder plot.
A habitual prankster who has scared almost 100 people.
- 108: How many people she'll have to scare in order to break her father's record and have him buy her ice cream.
- Establishing Character Moment: She's introduced trying to scare Raiko, only to fail.
- Everyone Has Standards: As much of a prankster as she is, she wouldn't fool around in a serious situation.
- Hidden Depths: Scaring people aside, she turns out to be a surprisingly caring individual. While Kamen had written Mika off as a nuisance, she actually becomes friends with her in her second diary entry.
- O.O.C. Is Serious Business: She's dead serious when she announces Momoko's "death."
- Pervert Revenge Mode: She gives Kotoba a good whack whenver he does something perverted.
- The Prankster: Likes playing practical jokes on people.
- Shinigami: She dresses as one for the party, and wields a cardboard scythe.
- Signature Laugh: "Akukukuku!"
- Third-Person Person: Constantly refers to herself in the third person.
A popular musician in the class's school, who recently started going out with Hiro.
- Affectionate Nickname: Kamen calls her "Momo."
- Alliterative Name: Momoko Mori.
- All Take and No Give: Surprisingly enough, she ends up on both ends of the trope. In most of her relationships with her classmates prior to meeting Kamen, Momo was a Giver whose kind and helpful nature was frequently abused. When it came to Kamen, however, Momo gradually ended up becoming the Taker, with Kamen noting how Momoko always asked Kamen to do thigs for her.
- Clingy Jealous Girl: She apparently came off as this on a few occasions. She got angry with Runa for talking to Hiro, and her attitude apparently upset Hiro enough that they argued about it. In fact, she was so easily jealous that when Kamen warned her about Hiro, she suspected Kamen of trying to break them up, and threatened to end their friendship if she persisted.
- Deconstructed Character Archetype: She deconstructs the Clingy Jealous Girl. Because she doesn't have many friends, she's somewhat possessive of the few people who are close to her. Her inability to accept that Hiro never cared for her leads to her lashing out at Kamen when Kamen tries to tell her the truth, and plotting to kill Hiro and frame Kamen for murder when she believes that he's cheating on her with Kamen.
- Dramatically Missing the Point: She doesn't realize that Kamen's trying to help her, and instead accuses her of trying to steal Hiro away.
- Driven to Suicide: She hangs herself in the guest room. The first time, she's faking it, but when Raiko returns, she's actually dead.
- Dude Magnet: She gets quite a bit of attention from the boys, often receiving love letters on a regular basis. In the cast alone, two boys and one girl are interested in her.
- Dude, Not Funny!: After Raiko flippantly says she'd rather kill herself than wear the costume her mother got her, the usually cheerful Momoko tells her that suicide is no laughing matter. This may be because Momoko is planning to commit suicide herself.
- Fatal Flaw: She has trust issues as a result of being taken advantage of in the past, which leads to her being clingy by nature, and turning murderous when she learns about Hiro going behind her back.
- Manipulative Bitch: She plays Kamen, Kotoba and Hiro like fiddles as part of her grand murder plot.
- Murder-Suicide: She kills Hiro (as well as Kotoba if you can't save him in time), then herself.
- Rose-Haired Sweetie: Subverted. While she has pink hair and seems like a nice person, she's actually, a clingy girl who masterminds a murder plot.
- Shrinking Violet: She's fairly introverted and shy, but not when she's on stage.
- Thanatos Gambit: Her entire plan in the game is to kill Hiro, Kotoba and herself, then pin the blame on Kamen.
- Walking Spoiler: As the true murderer and main antagonist of the game, she is naturally this.
- Woman Scorned: Her motive in a nutshell, since she wants revenge on Hiro for being unfaithful to her, and on Kamen for supposedly stealing him away.
- You Have Outlived Your Usefulness: Does this to Kotoba. Killing him wasn't her original plan, but after he fulfills his role, he knows too much for her to keep him alive.
Momoko's boyfriend, as well as an arrogant individual who wants to be the best at everything.
- Acquired Situational Narcissism: After acing his first test, he became obsessed with outdoing everyone else.
- Asshole Victim: He's the biggest jerk in the cast, and his cheating on Momoko results in his death.
- Attention Whore: He's an egomaniac who wants to be the center of attention. He only became interested in Momo because of how popular she was.
- The Charmer: He wormed his way into Runa and Momoko's hearts, but didn't feel anything for them at all.
- Didn't Think This Through: Even if he didn't know Kamen was a lesbian, he should have realized that being willing to callously dump her best friend wouldn't have won him any points with her.
- Freudian Excuse: His parents neglected him, resulting in him trying to seek out attention. His father's womanizing habits probably rubbed off on him, too.
- Freudian Excuse Is No Excuse: Raiko comments that the above Freudian Excuse explains his behavior, but doesn't justify it.
- Hate Sink: He has no redeeming qualities, and his deplorable treatment of the girls who love him kickstarts the story's conflict.
- Jerkass: From the very beginning, he comes off as an arrogant and unlikable jerk.
- Jerk with a Heart of Jerk: You might initially think that there's something good about him underneath his harsh exterior, but no. The more you learn about him, the worse he turns out to be.
- Red Herring: He comes off as suspicious, especially considering his telling the story about the murder-suicide, and Momoko ending up hanging herself. In fact, he's the correct choice for the prime suspect just after you question everyone. However, he didn't actually commit the murder (especially since he's a victim), and accusing him results in Kamen being accused of his murder, leading to a bad ending.
- White Hair, Black Heart: He has white hair and is by far the most unpleasant person in the cast.
A brutally honest girl who, for some reason, can't stand Raiko. She's Momoko's best friend.
- Because You Were Nice to Me: She grew to like, and possibly be attracted to, Raiko after the latter stood up for her.
- Broken Pedestal: In a sense, Raiko comes off this way to her. A week after Raiko saved her from being falsely accused of shoplifting, Raiko stands her up, and returns to school as a completely different person.
- Brutal Honesty: According to Raiko, she says whatever's on her mind. Her diary entry implies this is because she's bottled up her feelings for so long.
- Establishing Character Moment: Her introduction involves her gushing over how "sexy" Momoko's costume looks, warning Hiro not to break Momoko's heart, and then making snide comments about Raiko, summing up her three most important relationships.
- The Gadfly: She often enjoys teasing Momoko, who responds in kind.
- Gayngst: She angsts a bit about being gay, her friend not loving her back, and having to keep it secret due to worrying about how it might affect her friendship.
- Incompatible Orientation: She's a lesbian, but Momoko isn't, so Kamen decides not to tell her. Because Momoko ends up suspecting that Kamen wants to steal Hiro away, never realizing that Momoko loves her she ends up regretting that decision.
- Jerkass: She constantly mocks Raiko for her gloomy demeanor, and doesn't get along with Hiro, either.
- Jerkass to One: She's significantly meaner to Raiko than anyone else. Even Hiro, whom Kamen hates for good reason, mostly gets snarky remarks that could be mistaken for good-natured teasing.
- Jerkass Realization: After Raiko helps clear her name, Kamen realizes how cruel she was to her and apologizes.
- Jerk with a Heart of Gold: While she's not exactly a nice person, she does undeniably care for Momo.
- Laughing Mad: After relating everything that led up to the murder, she erupts in a fit of mirthless laughter.
- Master Actor: As vice-president of the Drama Club, Kamen is a talented actress. Because of that, the others wonder if her reactions after being accused of the murders are genuine.
- Meaningful Name: Her name means "mask" in Japanese. The achievement for reading her Diary Entry B is "Unmasked."
- The Only One I Trust: She becomes this for Momoko, although it takes almost two years for her to achieve that status. That said, Momoko refuses to believe what Kamen says about Hiro, and threatens to cut off her friendship if Momoko tries to get between them.
- Second Love: It turns out that before Momoko, she'd fallen in love with Raiko, and even before that, had another crush on a girl when she was 11.
- Unwitting Instigator of Doom: She failed to delete the messages from Hiro on her phone, resulting Momoko reading them and becoming jealous.
- Walking Spoiler: It's difficult to talk about her without spoiling a twist of some sort, such as her sexuality and her true feelings for Reiko.
- You Gotta Have Blue Hair: Her hair is green, like the twins. The resemblance becomes a plot point, since Momoko intended to use the green wig to impersonate Kamen.
Taiko's best friend, and a notorious pervert.
- Abhorrent Admirer: To Momoko. As a result of his constant and unwanted advances of him, she comes to hate him enough that she wouldn't mind killing him.
- Asshole Victim: He can die as a result of the fire. Considering his perverted personality, the group doesn't feel too bad for him.
- Bi the Way: He lusts after boys and girls, Momoko most of all.
- A Date with Rosie Palms: He admits that he's tired because he stayed up all night masturbating to pornography.
- Cruel and Unusual Death: Being burned alive is a terrible way to go.
- The Friend Nobody Likes: As a result of his perverted personality, no one really likes him. In fact, even his best friend, Taiko, freely describes him as an idiot.
- Gratuitous Foreign Language: As a master of several languages, he likes using foreign words and phrases, particularly when trying to pick up girls.
- Handsome Lech: He's a notorious pervert.
- He Knows Too Much: While he wasn't one of Momoko's targets, she decided to kill him to prevent him from spilling the beans about their plan, since the final stage involved her framing Kamen for the deaths.
- Going Commando: He doesn't like wearing underwear.
- Scars Are Forever; If he survives the fire in the basement, he'll likely have permanent scarring.
- Stalker with a Crush: To Momoko. He constantly sent her letters and followed her around, but backed off after Kamen threatened to tell the police.
- Unwitting Pawn: To Momoko. Since Momoko needed an additional accomplice to pull off her plan, she chose him because he was easy to manipulate, and she hated him enough that she wouldn't mind disposing of him.
- Wounded Gazelle Gambit: He pretends to fall and injure himself to convince Taiko to stay put.
A kind and helpful boy that has a strong sense of justice.
- Commander Contrarian: He serves as Raiko's main opponent in the game's climax.
- Cry for the Devil: In the version of the good ending in which Kotoba lives, he visits Momoko's grave (instead of Kotoba's) and expresses pity for her despite everything she did.
- Disappointed in You: He says this to Raiko if she fails to convince him of the identity of the mastermind behind the killings before refusing to listen to her, resulting in a bad ending.
- Dude, Not Funny!: He makes it clear that Rie's plan to stage a murder was in exceptionally poor taste.
- Fatal Flaw: The fact that his friendship with Kotoba is strong enough to cloud his judgment. He's reluctant to believe the more serious accusations against Kotoba, even if they're true, and when Kotoba either dies or is badly burned, he lets his rage get the better of them and blindly accuses Kamen.
- Hypocrite: Despite stressing the importance of pursuing the truth, no matter how painful it can be, he has a bad habit of blindly trusting Kotoba. He also is overly quick to suspect Kamen, since while he has his reasons, he's missing some details that point to the true culprit's identity.
- Jerkass Realization: If Raiko manages to convince him of Momoko's guilt, Taiko realizes how unfair and irrational he was in suspecting Kamen, and apologizes.
- My God, What Have I Done?: After Raiko pokes holes in his theory, Taiko becomes deeply ashamed of suspecting Kamen.
- Nice Guy: He's generally a kind and upstanding person. While he does become suspicious of Momo after Kotoba dies, after he calms down, he apologizes to her.
- Ordered Apology: Raiko demands that he apologizes to Kamen. He complies, not just to appease Raiko, but because he generally feels bad about going too far in suspecting her.
- This Is Unforgivable!: He says that he'll never forgive Raiko for taking sides with a murder. After he calms down, though, he says that his rushing to suspect Kamen is unforgivable.
- Took a Level in Jerkass: He becomes significantly more shorter-tempered and argumentative in Chapter 5, and is quick to pin the crimes on Kamen.
Raiko's older sister, who died four years before the start of the story.
- Affectionate Nickname: Nobara calls her "Ghostly," even before her death.
- Cool Big Sis: While Reiko was alive, she and Raiko were very close.
- Driven to Suicide: Vaguely implied. Reiko died very suddenly, and Raiko blames herself for her sister's death, so it's possible that something happened and, Raiko, with no one to turn to, killed herself.
- Noodle Incident: Apparently, something happened and Raiko, as a result of jumping to conclusions, caused Reiko's death.
- Posthumous Character: She's been dead for four years.
- Walking Spoiler: It's almost impossible to talk about her without revealing the root cause of Raiko's issues. In fact, since Raiko once describes herself as Rihatsu's "one and only daughter," the fact that she even has a sister is a surprise.
Raiko and Reiko's mother.
- Absurdly Youthful Mother: She was born on March 10, 1975, and had her first daughter on November 5, 1992, making her seventeen years old at the time of the birth.
- Affectionate Nickname: She calls her husband "Yuuyuu."
- Amazingly Embarrassing Parents: She often embarrasses her daughter by teasing her.
- The Gadfly: She enjoys teasing her daughter. According to Extra Scene B, they used to enjoy teasing each other a lot when Reiko was still alive, and Rihatsu hopes doing so will bring Raiko out of her shell.
- Hidden Depths: She doesn't just tease her daughter for the fun of it, but in the hopes of bringing her out of her shell and helping her return to how she used to be before Reiko's death.
- Strong Family Resemblance: She strongly resembles both her daughters, especially when it comes to her hair color.
Raiko and Reiko's father, and Rihatsu's husband.
- Affectionate Nickname: He calls his wife "Ricchan," and his daughters "Rai-chan" and "Rei-chan."
- Last Episode, New Character: He appears in the good ending.
- What the Hell, Hero?: He tells Rihatsu that she shouldn't tease Raiko so much. He's sympathetic to her reasons, but says Raiko will need time to get back to the way she used to be.
Nobara's father. He's best friends with Raiko's father.
- Amazingly Embarrassing Parents: He's overly affectionate with his daughter and Raiko, much to their disgust
