Adeline "Addy" Martin
Super High-School Level Sculptor
Adeline is an energetic girl who became well-known after the sculptures collecting in her mother's backyard began to attract the attention of art collectors. When confronted by Yukiko, Addy admitted to having killed Shinya in what she believed to be self-defense. She later becomes the chapter 5 murder victim, killed by blood loss from a slashed throat.
- Child Prodigy: Addy has been making figures nearly every day since childhood, and was first noticed professionally in middle school.
- Dirty Coward: She lies during the second trial about the file so she wouldn't be executed, and only confesses to Yukiko to save her reputation among the other students.
- Disappeared Dad: She states in one of her ask memes that her father left when she was a small child.
- Doting Parent: Her mother provides for her every want.
- Manslaughter Provocation: She killed Shinya in what she believed to be self-defense.
- Nice Girl: According to her profile, "She is also very personable and is good at making people like her in order to get a sale." But not, apparently, nice enough to confess to being the second murderer to avoid Monobear crippling a random student as punishment for the students getting it wrong.
Super High-School Level Microbiologist
Born out of wedlock, Arisa grew up in the city slums. Excelling in her studies led to her parentage being made known and getting moved to Japan on the government's time, where she works with the World Health Organization. Her current project is the Disease Hybridization Forecast and Impact Committee. Responsible for murdering Mimi, and was correctly pinned as the culprit during the sixth trial.
- Awesomeness by Analysis: She's very analytical and can get through stacks and stacks of data very quickly, which is useful since she's created and is now the leader of the Disease Hybridization Forecast and Impact Committee.
- Cruel and Unusual Death: Arisa is shrunk down and placed in a terrarium. There's a hole in the terrarium, so if she could get to it, she could escape. But to do so, she must climb on various bacteria that appear. Two frogs with Monobear-style eyes suddenly appear, devouring the bacteria one by one. Arisa manages to escape until she gets to the very last bacteria, but then has no other escape route, and one of the frog's tongues finally latches onto Arisa and eats her.
- Disappeared Dad: Arisa's father, Masaru Sato, wasn't around when she was growing up.
- Heroic Bastard: She was born out of wedlock to a well-known male scientist and an unknown woman, and her parents never married, making her technically a "bastard". Now she's leading public-edge health research.
- In the Blood: Inverted, as Arisa follows in the footsteps of her brilliant scientist father with no drive towards evil.
- Official Couple: With Hidehisa. Not that anything comes of it, however, since the love confession happens in the chapter 6 trial, which is also when Arisa is executed. However, they reunite in the afterlife.
- Self-Made Man: Grew up in the slums, but excelled in her studies and consequently got moved to Japan to pursue microbiology further.
- Well-Intentioned Extremist: In three different ways, no less. One, to atone for her role in instigating chapter 4's mistrial. Two, so the person she killed could be with her deceased lover. Three, so she could win Monobear's "Mastermind information motive" and then share that information with all her peers in order to help them.
- Wise Beyond Their Years: Arisa is always approaching things with a mature attitude, and to date has not had a breakdown of crying, anger, or any particularly unsuitable behavior. Logic seems to be easy for her, and she's been seen to be calling out others on unsuitable behaviors. Likely invoked by Disappeared Dad and growing up on the wrong side of the tracks.
Super High-School Level Stunt Driver
- Almost Out of Oxygen In chapter 8's morgue investigation with Naoto and Hisae, he passes out due to smoke inhalation.
- Ascended Extra: Chris Peril was not originally accepted into the Doubt Academy White roleplay, but the creator of Barclay, the SHSL Deep-Sea Diver, unexpectedly had to resign from the roleplay for personal reasons, so Chris Peril was the lucky (or, given the subject matter of the roleplay, should that be unlucky?) guy chosen from previously submitted applications to take Barclay's place.
- Badass Driver: Is very talented behind the wheel of a car, as well as a few other vehicles. Began doing more dangerous stunts at age 15 and has upped the danger since.
- Dark Horse Victory: Sort of, if "surviving" counts as a victory. Chris Peril's character wasn't even originally supposed to be in this game; his spot was originally taken by a SHSL Deep-Sea Diver named Barclay. Chris Peril was a last-minute replacement, but he's one of the people who survive to endgame.
- Dramatic Unmask: When the students get chapter 2's culprit wrong, Chris Peril gets so frustrated that he throws off his helmet, revealing his face for the first time. He has brown hair, blue eyes, and freckles on his nose.
- Like Father, Like Son: Picked up his love for driving from his father, who was a famous stock car racer at one point.
- Near-Death Experience: During chapter 8's morgue adventure, Chris inhales enough smoke to the point of his inner monologue quality beginning to degrade. It scared Hisae to a good degree.
- Precision F-Strike: During the endgame, Chris condemns everyone who doesn't vote to bring their dead friends back, which includes Eiji, Hisae, and Jun. Then Chris informs them that the hard drives are leaving whether they like it or not, and if they want to disagree, "Try me, I fucking dare you." And just to add to the shock of his swearing, he says that while pulling a machine gun on the three dissenters to make sure they go along with the group's decision to save their dead friends.
- Send in the Search Team: With Naoto and Hisae. During chapter 8, Naoto brought Hisae and Chris together to search inside of a secret room in the morgue to look for clues about the Mastermind. Things didn't go as planned, however, when Chris activated a tripwire that in turn started a fire. The search ends with Naoto and Chris unconscious and a blubbering Hisae.
- Stage Names: His real name is Hideki Takahashi.
- X Must Not Win: In Chris Peril's case, it's "Monobear must not win." After the students get chapter 2's culprit wrong, resulting in Monobear picking a student to cripple in lieu of an execution, Chris Peril says Monobear won't win, Chris will die before he lets Monobear win.
Super High-School Level Show Host
Eiji always loved to be the center of attention from childhood. He hosted his own extremely popular show, called "The Eiji O Show!" before quitting, desiring a normal school life. Instead, he was invited to Hope's Peak Academy. Survives to endgame.
- Anger Born of Worry: After trial 4, Eiji declares that he hates Larry and Kazuya the most after both offered to die (In Kazuya's case, YET AGAIN.). He then exits the area and punches the elevator out of anger.
- Attention Whore: In an unusual example of this trope, he's required to be this, since it helps him in his SHSL talent of being a host. He actually stopped doing this shortly before being invited to Hope's Peak so he could have a normal school life.
- Bath Suicide: Attempts this during chapter 8.
- Bishie Sparkle: This is mainly pertaining to his clothes and bright smile.
- Broken Pedestal: It turns out Kanon was his idol, so he is extremely apologetic when Kanon turns out to be chapter 3's culprit and must be executed.
- Dark and Troubled Past: Used to be part of a gang. Said gang once killed a girl.
- Doom Magnet: Literally every close friend he has made died! His first best friend, who didn't even go here died as well. Can you say cursed?
- Driven to Suicide: The day the motive is given is also the day after Eiji learns of his mother's death. On top of this, he has fallen to despair due to several reasons related to the Spa. States in his suicide note that he has fallen to despair and is frightened that someone he cares for could be the mastermind, which he can't take.
- Get A Hold Of Yourself Man: At the end of trial 3, when Eiji slapped Kazuya for his continued offer to die for everyone.
- Goodbye, Cruel World!: Sends Katsuya a suicide note before he hits the bath and attempts to end his life.
- Harmful to Minors: According to the read more Eiji posted during chapter 4, he watched his friend Genki as she was stabbed to death by his cult. He was supposed to be next. That was, until the police came. It was too late for Genki, however.
- Hit Me, Dammit!: In order to repair his friendship with Larry, Eiji asked him to punch him in the face and let him do the same during Chapter 5's Abnormal Days.
- It's All My Fault:
- How he feels about his friend dying in front of him when he was 12 years old. The truth is, he was chained to a desk and forced to watch as his best friend at the time was murdered.
- At the end of trial 6, he blames himself again, for not being a good friend to Arisa and Hidehisa.
- He blames himself before and after trial 7 as well, for not protecting Kazuya and Jaejin. He also believes that Jun and Yukiko killed because he wasn't a 'good enough friend'.
- Large Ham: About everything. Means what he says. When embarrassed, instead of saying something else or avoiding the subject, he'll talk about it in length, with more volume.
- The Matchmaker: He seems to take notice when two of his close friends have romantic feelings for each other. This was evident in his last encounter with Tomiko and Kazuya in chapter 4.
- Missing Mom: We find out in chapter 8 that she died sometime while Eiji was at school, thanks to a newspaper article in his room. His mom, Ishizu Oshirou, was the object of his obsessions since he was 12. He looked for her for a good 7 years.
- No Indoor Voice: He usually talks loud on the show, so he supposedly isn't used to talking normally.
- Official Couple: With Katsuya; they've even had a "night of passion" together, as we learn during Eiji's bout of survivor guilt after chapter 7's trial. Interestingly enough, however, a recent post has revealed that he very much cared about "his funny girl", meaning Koemi, and he still obsesses over her in his room and writes to her in his diary. It is possible that Eiji might have hooked up with Koemi instead if Koemi hadn't been the first murder victim.
- Parental Abandonment: We find out when Himeji speaks to him in Chapter 3 that Eiji's mother left him, stating that she didn't need the family anymore. We find out in Chapter four that this was linked to why he joined the cult in the first place.
- Real Men Wear Pink: Is rather domestic and independent, considering the fact that his father is never home. He has to cook, clean and take care of his younger brother most of the time.
- The Rival: Eventually becomes this to Naoto. There's no real personal event that sets it off; they just frequently make opposite decisions and eventually can't stand each other. Surprisingly, this does not result in either of them killing the other; in fact, they both survive to endgame.
- Rousing Speech: Gives an angry one backing Marian up to Shinya and Kazuya when the latter two offer to sacrifice themselves in Trial One.
- Scars Are Forever: Eiji has scars down his back due to cult self infliction activities. This was to bring them 'closer to the spirits'.
- Security Cling: Jumps into Larry's arms upon discovering Kyo's death.

The food snob to lead all food snobs, Fumiko adores all things food. She is feared all over the world by those in the culinary world, as a review from her is the ultimate authority. She's the first culprit; she murders Koemi, but the students manage to correctly figure out it was her.
- Big Eater: Which makes her better at her SHSL talent of being a food critic.
- Caustic Critic: Which makes her better at her SHSL talent of being a food critic.
- Cruel and Unusual Death: Fumiko is executed as the first culprit by being sent to a giant table full of food, befitting her SHSL talent as Food Critic. There is a giant Monobear at the end of the table holding a knife and fork eagerly, as though anticipating his meal. Fumiko tries to get off the table, but the tablecloth suddenly becomes a "treadmill" and forcibly drags her over to the giant Monobear, who stabs her to death with his fork.
- The Engineer: Very minor example, she can repair household appliances.
- Impaled with Extreme Prejudice: Her ultimate fate, because she's executed by a giant Monobear stabbing her to death with a fork.
- It's All My Fault: Being the first killer, Fumiko blames herself for starting the chains of deaths.
- My God, What Have I Done?: In the afterlife, Fumiko has a moment like this in chapter 4, because chapter 4's trial was ultimately decided by a tiebreaker vote from the dead students—and Fumiko was one of the people who voted for Ritsuka, who was ultimately convicted but turned out to be innocent. That means Fumiko contributed to the innocent Ritsuka being killed.
- Official Couple: Becomes this with Takahiro in the afterlife, although this wasn't revealed until Doubt Academy White was over and the "dead students blog" was opened to the public.
- Picky Eater: Which makes her better at her SHSL talent of being a food critic.

- Jack-of-All-Trades: Out of curiosity, Hisa has worked in every performing aspect of the family business and has some skill in them.
- Master of the Mixed Message: His profile, actually, not he himself. His profile reads, "As a showman by trade, Hidehisa is quite the charismatic character. That "dazzling personality of his has gotten him places... if yknow what I mean." This could be innuendo, or it could be referring to something completely innocent. It was deliberately left vague.
- Official Couple: With Arisa Sato. Not that anything comes of it, however, since the love confession happens in the chapter 6 trial, which is also when Arisa is executed. However, they are reunited in the afterlife.
Super High-School Level Crossdresser
He became famous for his looks and great fashion sense. His public persona is rather elegant and refined, but in reality Himeji is a vulgar and loud-mouthed egotist. Deep down though, he can be a good person. Deep, deep down. Is killed during a failed attempt to escape the park along with Yoon-ji.—-
- Bitch in Sheep's Clothing: His media persona is refined and elegant, but in all actuality he is nothing like that.

Born into a family of body modifiers, Hisae obtained her license at the young age of 14. Many people seek her out to do their piercings, if only to say that they got a piercing from her. Survives to endgame.
- Daddy's Girl: Minor example: she became a SHSL Body Piercer because her father shared his trade with her.
- Follow in My Footsteps: Everyone in Hisae's family has "learn a body modification trade" as practically a rite of passage. None of them have any problem with this, and in Hisae's case, her body modification trade turned out to be piercings, which she's Super High-School Level good at.
- Heavy Sleeper: She's capable of falling asleep in any position.
- Lazy Bum: After the body of Kyo is announced, the sprites used depict Hisae wearing her pajamas. It becomes a common theme in the investigations following, with the exception of Mimi's. It's also revealed that she normally wears contacts, but ceased wearing them in favor of her glasses.
- The Medic: A minor example; in her profile, it says she can only cure infections, but it's revealed in chapter 8 that she is also trained in CPR.
- Not So Stoic: While normally stony-face, she breaks down in tears after a letter Kiyoshi gives her. Does so again in chapter 8 when faced with Naoto and Chris's close call with death.
- Send in the Search Team: With Naoto and Chris. During chapter 8, Naoto brought Hisae and Chris together to search inside of a secret room in the morgue to look for clues about the Mastermind.

- Why Did It Have to Be Snakes?: Chapter 8 revealed that Hisae is afraid of fire.
Super High-School Level Maknae
The youngest member of the eight-member idol group 'PLAN8'. Don't let his fresh face fool you, though; his quick feet, sharp tongue, and incredible passion make him one of the greatest male idols in the industry. The eighth victim of Doubt Academy White, killed by epinephrine-induced heart failure.
- Berserk Button: When Larry tries to derail the vote in chapter 3 on the grounds of not enough evidence, this is the second time he's done this, and Jaejin finally blows up at him. His face turns red and he screams at Larry for accusing them of jumping to conclusions when he didn't do any of the investigation himself.
- Beware the Nice Ones: In chapter 3's trial, Jaejin gives a nasty to speech to Kanon, because Jaejin believes Kanon is the culprit. Even Jaejin's sprites are drawn with angrier than usual expressions.
- Heroic BSoD: A minor example: Monobear's second motive is to threaten to end a random student's career with an injury unless a murder takes place. Jaejin is the most badly affected by the announcement, because given his talent, any injury at all could ruin him, from a broken leg to even a broken finger.
- Idol Singer: He's a member of an idol group. But it's not his SHSL talent since, unlike Sayaka Maizono's SHSL talent of being an Idol Singer, Jaejin isn't proficient at idol singing but rather is proficient at being "the youngest member of a group", which is what the Korean word "Maknae" means. He seems to be the most skilled at dancing.
- It Was a Gift: His sister gifted him one of his two Pluto symbol necklaces before leaving for his idol training, which Jaejin claims is his Good Luck Charm. He later gifts the necklace to Naoto Ueyama, and receives a scarf in return.

- Omniglot: Fluently speaks both Japanese and Korean, since his father is Japanese and his mother is Korean. He also spent three years in Korea.
- Rant-Inducing Slight: In chapter 2's trial, after Jun calls Yukiko "my lady" one too many times, Jaejin snaps at Jun that Yukiko's words shouldn't just be taken as faith, and then Jaejin angrily reminds everyone else, at length, that they are attempting to find someone to execute, so anyone making baseless conjectures is not contributing to the group.
- Real Men Wear Pink: He's wearing a pinkish-purple Pluto necklace, and his eyes are pinkish-purple.
- "The Reason You Suck" Speech: After the students incorrectly vote for Ritsuka in chapter 4, Jaejin tells all his classmates in a long speech that they suck, because one, Jaejin himself didn't vote for Ritsuka this round, and two, Jaejin has always voted correctly so far. He was right to vote for Fumiko in chapter 1, he was right to vote for Addy in chapter 2 (although the students overruled him and voted it a suicide), he was right to vote for Kanon in chapter 3, and he was right about Yukiko being chapter 4's culprit. Jaejin works hard and has correct instincts, so those should have been allowed to take precedence over the students throwing out evidence because they thought the evidence was circumstantial.
- Stepford Smiler: A benign example, since he isn't always the cute maknae everyone loves, but can easily slip into that persona since "Made for TV" is one of his skills.
Super High-School Level Game Developer
Mostly doing Role playing Games and Visual Novels, Jun excels in storytelling more than technical gameplay, though he does create games for all genres. Despite being gifted with words, he often comes across as shy and not very talkative. After the second trial ends with a mistrial over a mistaken suicide, Monobear declares he'll act out the motive and randomly cripple one of the students for life. Jun's the one chosen, and has his eyes gouged out. In chapter 7, Jun confesses to Jaejin's murder, but is exonerated due to someone else winning more votes than him, winning Monobear's "immunity" motive. Survives to endgame.
- Anguished Declaration of Love: Upon learning that he's about to be crippled, he gives everyone a speech to inspire them, and included in that speech is a confession that he loves Yukiko, "Milady". He loves everything about her, would be willing to give her the sun and moon, and would she consider going out with him?
- Eye Scream: When Monobear punishes the students after the second trial by crippling one of them, poor Jun gets his eyes pecked out by crows.
- Heroic BSoD: Following his blinding, he struggles with feeling useless and worthless.
- Karma Houdini: He murders Jaejin in chapter 7, but because Yukiko received more "total votes" for Yukiko's separate murder, Jun wins Monobear's "immunity motive" and thus not only gets off scot-free for murdering Jaejin, but cannot become a victim for one more chapter. Then he survives to endgame.
- Naked First Impression: Minor example. Upon meeting Jaejin and going back to his room to clean up, Jun accidentally exposes himself to his new friend.
- Painting the Fourth Wall: His posts sometimes include graphics resembling game text windows. Making new friends is signified with "Congratulations!! A New Party Member Has Been Added!"; a death means "This Route Is Now Locked!!"; his interruption is "That option is unavailable!!"
- Official Couple: With Yukiko. However, this is cut short in chapter 7 when Yukiko is executed for murdering Kazuya. And Jun can't even be with Yukiko in death, because Jun murdered Jaejin and successfully won Monobear's "immunity" motive.
Super High-School Level Medium
Gifted with supernatural sensitivities from birth, Kanon has gained both positive and negative attention for her ability to commune with the dead. Technically responsible for Kyo's murder — or rather, the spirit Yuu Hideyoshi killed him while possessing her. Her classmates pinned it on her.

- Curtains Match the Window: Both her eyes and her hair are a purplish-white.
- Creepy Good: Kanon puts out a strange aura that creeps people out, but she's really not all that bad. Then it's doubly subverted. One, it turns out Kanon is chapter 3's murderer, subverting the "good" part of "creepy good"... but two, that is subverted when it turns out the real murderer is the spirit who forcibly possessed Kanon; Kanon herself was innocent and had no knowledge of what her body did.
- Cruel and Unusual Death: Hers is set in a haunted house, in a room filling with poison gas. The only door out leads to something that pulls her inside and slams it shut behind her, leaving her stuffed bunny to soak in the blood seeping beneath the door. What's left of her body was stuffed into a second bunny that was tossed back into the room in the end.
- Girls Love Stuffed Animals: She carries around a stuffed bunny for undisclosed and mysterious reasons.
- Motive Rant: After Kanon's declared to be the murderer, Yuu takes over and reveals they were really responsible, and rants about how this was the only way to protect her.
- My God, What Have I Done?: In the afterlife, Kanon has a moment like this in chapter 4, because chapter 4's trial was ultimately decided by a tiebreaker vote from the dead students—and Kanon was one of the people who voted for Ritsuka, who was ultimately convicted but turned out to be innocent. That means Kanon contributed to the innocent Ritsuka being killed.
- Nice Job Breaking It, Hero!: Yuu decided the best way to save Kanon was to force her graduation by possessing her and murdering three students. This only succeeded in getting Kyo and Kanon killed. Whoops.
- Nothing Is Scarier: None of the witnesses get a clear view of what murders Kanon, as it takes place behind a closed door. They only have her screams, horrific sounds, and her blood seeping underneath the doorway to go by.
- Official Couple: With Shinya in the afterlife, though this wasn't revealed until Doubt Academy White was over and the "dead students blog" was opened to the public.

- Take Me Instead: Tries to take the rap for killing Shinya in chapter 2's trial.
- What Did I Do Last Night?: Does not recall what happened around the time the murder of Kyo occurred. Making matters worse, some of her beads were discovered in a trash can near the crime scene. It turns out it's because a spirit possessed her and murdered Kyo, so from a certain point of view, she can't remember what happened because she was Kyo's murderer.
- Willing Channeler: Kanon's specialty is possession-based communication with the dead.
Super High-School Level Journalist
A rather intrepid journalist, Katsuya will do anything to get his story, even going so far as meddling into government affairs to gain evidence. He's revealed to be the Mastermind.

Super High-School Level Card Player
A gifted number cruncher. When his father realized this, he forced his son to apply himself harder in school; this backfired, the tests and stress becoming far too much for him. Poker and trading card games became an escape, the only thing he did outside of studying. Though he sees it as a 'worthless hobby', he was accepted into Hope's Peak for his skills, much to his shock. The seventh victim of Doubt Academy White, killed by cyanide-induced hisotoxic hypoxia.
- Dark Secret: Played for Laughs. Much like Naegi, his 'dark secret' is more embarrassing than anything else: farting in English Class.
- Driven to Suicide: A note found near his body implies he chose to kill himself in order to prevent anyone else from successfully winning immunity from Monobear's super motive. Naturally, this isn't the case.
- Education Mama: His father pushing him to excel is responsible for a lot of his issues.
- Evil Laugh: He fakes villainous laughter when trying to falsely confess to Shinya's murder in chapter 2's trial.
- Hearing Voices: As of chapter 3, Kazuya seems to be hearing a dark version of himself talking to him, though it sounds muffled to him. It wants him to kill himself.
- Heroic Self-Deprecation: Considers his talent to be nothing more than a 'worthless hobby', and thinks that the only reason his title is SHSL Card Player is because they couldn't call somebody a SHSL Loser.
- Shout-Out: In the third trial, when attempting to protect Kanon, he shouts at Mimi, "THAT'S NOT ENTIRELY CORRECT", but he is accompanied by a hand-drawn pose that makes him look like Makoto Naegi or Hinata Hajime shouting "YOU'VE GOT THAT WRONG!"
- Take Me Instead:
- Near the end of Trial One, Kazuya tries to offer himself in Shinya's place after Shinya tries to get himself executed.
- He does this again in Trial Two, after Kanon tries to do so first.
- He continues to offer himself up in subsequent trials. It really starts to get on his classmates' nerves after a while.
- Once caught, his murderer points at this habit as some sort of sick justification, claiming she just gave him what he wanted.
Super High-School Level Theologian

At the age of 12, he mastered meditation and claimed to have reached Enlightenment, and ever since has had an air of omniscience and gives spiritual advice to those who ask. Survives to endgame.
- Can't Get Away with Nuthin': He once teased a girl about how much she loved peanuts. This led to him getting hospitalized.

- Preacher's Kid: His father is a minister.
- Where There's a Will, There's a Sticky Note: Scribbles down a will in his diary after Shinya's trial, but the will becomes unnecessary because he survives the game.
Super High-School Level Comedian
Though coming from a very serious family, Koemi learned the art of telling the best horrible jokes from her neighbor, along with some other tricks. She's the chapter 1 murder victim, dying from blood loss caused by a slashed throat.
- Berserk Button: In the afterlife, she surprisingly turns out to have one in chapter 4—it turns out Koemi's berserk button is accusing Larry of murder, which she feels only morons would do.
- Fortune Teller: In the afterlife, Koemi briefly pulls a "fortune telling" act where she advises Fumiko to make sure to smile when talking to a boy she likes.

- Pungeon Master: Her SHSL talent, along with all other forms of comedy.
- Purely Aesthetic Glasses: The glasses are there mostly just because they run with her heart motif.
- Sacrificial Lamb: Is the first murder victim, and the fact that it happened to a comedian sets the tone for the grim atmosphere of the mutual killing game.
- Shout-Out: In the afterlife, at one point Koemi shouts "DON'T MAKE ME LAUGH!"...which is accompanied by a picture of Koemi doing the "interrupting" pose from Danganronpa 2: Goodbye Despair that usually preceded a Cross Sword segment.
- Stand-Up Comedy: Her SHSL talent, along with all other forms of comedy.
- Stress Vomit: In the afterlife, seeing the gruesome nature of how chapter 4's murder victim was killed causes Koemi to throw up a few crackers and some tea and water.
- Too Good for This Sinful Earth: Everyone saw Koemi as a cute little girl (even some who only knew her as a stranger), so most of the students are royally pissed off that she was the first murder victim. The only ones who aren't pissed off are either the killer, or the ones who are calm enough to focus on finding out who the killer is and not care too much who it was who died specifically.
Super High-School Level Musician
He came from a long line of renowned classical musicians and was classically trained since he was in diapers. Despite this, he gravitated toward metal music and was disowned by his family for betraying the classical ways. He proved himself by quickly becoming a highly successful musician, acquiring a large fanbase in Japan and steadily gaining listeners overseas. He's the chapter 3 murder victim, killed by blood loss caused by multiple stab wounds.
- Black Sheep: In a family of classically trained musicians, Kyo loves metal. He loves metal a lot.
- Chairman of the Brawl: Loves threatening Monobear with the cafe's chairs.
- Cruel and Unusual Death: Subjected to heavy arsenic poisoning, vomits blood multiple times while confronting the perpetrator, and is riddled with stab wounds in his chest and abdomen, some of which were inflicted post-mortem.
- Did Not Get the Girl: As we learn from the "afterlife" blog, it turns out Kyo had serious, legitimate feelings for Yukiko, which went nowhere because Yukiko's heart belongs to Jun.
- Dies Wide Open: His corpse is locked in a gaze of horror until Yukiko closes his eyes.
- Go Out With A Bang: If Monobear was serious in his comment about Yukiko selfishly hiding away their "passionate necking", then apparently right before Kyo was murdered, he and Yukiko were making out. But then subverted; what actually turns out to have happened is that Kyo gave Yukiko a kiss after they bonded, but Yukiko still has feelings for Jun, so she left without doing anything else.
- Gratuitous German: Breaks into this when angered. For one example, when Monobear's "third motive" turns out to just be a reminder of the fact that they'll be trapped for the rest of their lives, Kyo starts shouting at Monobear how ridiculous it is that they need another reminder, and then he says, "Ich werde einfach töten dich, du Stück Scheiße. Ill find you soon enough, Bär." This means approximately "I'm just going to kill you, you piece of shit. I'll find you soon enough, bear."
- Hair-Trigger Temper: Almost attacks Monobear with a chair during the first motive announcement, then snaps at both Mimi and Shinya during the first trial. Later threatens to knock Kazuya out during the second trial in response to his attempt at self-sacrifice. Also throws a chair at Monobear during the third motive announcement.
- Headphones = Isolation: Subverted, as they're actually hearing aids; he's practically deaf without them.
- Heavy Metal: His preferred genre of music.
- Heroic BSoD: Suffers from this upon discovering Shinya's corpse, rendering him unable to properly investigate for the second trial.
- I'll Kill You!: Openly states that he will find and kill the person behind Monobear after it is declared that Jun will be crippled.
- Madden Into Misanthropy: In the afterlife, when Yukiko is executed, Kyo finally snaps and angrily yells at all his classmates that if they love killing innocents so much and don't understand that finding the Mastermind is all that's important, then hope is wasted on them and they're as good as dead.
- Meaningful Name: The kanji for 'Otonomiya' translates to 'Palace of Sound'.
- Parental Abandonment: Kyo's parents disowned him and forced him to live on the streets, all because he liked metal.
- Red String of Fate: It is never seen, but Kyo begins wearing a red string around his pinky finger after Shinya's trial in tribute to his dead brother.
- Street Urchin: Before Kyo became famous he lived on the streets and dumpster dived to eat.
- Underdogs Never Lose: Though he died shortly after declaring he would kill the mastermind, Kyo was instrumental in massively swaying the vote for Katsuya among the dead students.
Lawrence Larry Lang
Super High-School Level Boxer
Known as the "Golden Boy of Coney Island", Larry is an American raised in New York, who began to tour the world once he became famous. As a result his grades dropped, and taking the opportunity to enroll in a Japanese school while he was there on tour, Larry became eligible for acceptance into Hope's Peak. Responsible for murdering Mitsuko, and was correctly pinned as the culprit during the eighth trial.
- Berserk Button: When Renée is murdered in chapter 4, Larry spends three entire paragraphs screaming at his classmates for whoever the "coward" of a murderer is to show himself/herself so he can do nasty things to them.
- Big Applesauce: He was raised in New York.
- Book Dumb: In his backstory, but this was only temporary. His world tour of boxing caused his grades to slip while he was on the Japan leg of the tour, so he put himself in a Japanese school to fix his grades so they wouldn't disrupt his tour. This is what put him in the running for scouting by a prestigious academy.
- Cruel and Unusual Death: Rigged up to a Rock-Em-Sock-Em-Robots parody, with a Monobear with a controller behind him, forcing the robotic arms to which he's chained to repeatedly punch a giant steel Monobear robot, which breaks Larry's arms. Then the giant steel Monobear robot counterattacks, repeatedly pummeling Larry before finally uppercutting Larry's head off.
- Despair Event Horizon: Renée's death in chapter 4 causes Larry to decide he won't be saving anyone this time, and it's going to feel so good when someday he tears Monobear apart and stomps on his corpse.
- Important Haircut: Shaves off his afro in chapter 6.
- Murder by Mistake: He's chapter 8's murderer, but he wasn't actually gunning for Mitsuko, he was trying to kill Naoto instead. Unfortunately when Mitsuko showed up instead, he had to follow through on his murder plan or Mitsuko would tell someone about his intentions.
- My God, What Have I Done?: It turns out Larry was wrong about chapter 4's culprit, but the class voted for his incorrect guess largely thanks to a great deal of work he did in implicating who he thought was the culprit, and an innocent person was executed. This trope is Larry's reaction both to this innocent execution, and to the fact that now that his best efforts to undo his own damage have been ignored, he now knows what he himself put Naoto and Jaejin through when he previously shunted their efforts aside.
- Rousing Speech: Gave one in the first trial in response to being accused. Everyone was so moved that he wasn't ever brought up as a suspect again.
- Sherlock Scan: Skilled at reading body language, since he's a "counter puncher" in boxing terms.
- Super Reflexes: One of his skills is an extremely fast reaction time, which improves his boxing.
- To the Pain: When Renée is murdered in chapter 4, Larry threatens that when he finds out who killed her, he is going to tear the murderer's head off, reach inside the bloody stump the murderer calls a neck, and turn the murderer inside out with his bare hands. Then he will tear the murderer into so many pieces that there won't be enough left for Monobear to execute.
- Underdogs Never Lose: His backstory is that he was an underdog boxer, but he defeated a professional boxer in a three-round match for charity (it helped that he had already shown a natural aptitude for the sport in amateur tournaments). That's what got him started on touring the world and honing what was to be his SHSL talent: boxing.
- Well-Intentioned Extremist: He killed Mitsuko, but he was actually trying to kill Naoto, because he thought Naoto was a well-intentioned extremist willing to go to absurd ends to find the Mastermind. But as Larry freely admits, the manner in which he chose to try to "stop" Naoto turned Larry himself into a well-intentioned extremist.
Super High-School Level Rapper
A narcissistic party animal who was desperate to escape from her controlling parents. As a child, she constantly feared her punishment-happy family, but managed to escape them in middle school when she was recruited by a Korean music company that relocated her to Japan. Is killed during a failed attempt to escape the park along with Himeji.
- Blinding Bangs: She keeps them that way to "pique interest" in her fans and everyone else alike. As of chapter two, she no longer has them.
- Cannot Spit It Out: When she attempts to defuse the Dark Secret motive by confessing it, she starts turning blue and can't finish.
- Companion Cube: She's begun to frequently talk to a wall, which she affectionately named "Swagwall-chan".
- Important Haircut: She uses this as a way to try and "start from the beginning", even though she knows full well it's not going to change anything.
- Girl Group: Yoon-ji's the leader of a, you guessed it, girl group (who aren't girly in the slightest, apparently).
- Omniglot: Fluent in English, Korean, and Japanese.
- Stage Names: Her real name is Myung-hee Sang, apparently.
Super High-School Level Winter Guard
The star of her winter guard team, this energetic and eccentric young lady always wore a mask while performing, hiding her true appearance. Before entering Hope's Peak Academy, she gave one final performance wherein she removed this, revealing her face to the public for the first time. Turns out to be the culprit in Chapter 5, having killed Adeline.
- Cloud Cuckoolander: She engages in strange antics and has an unreadable demeanor, which can sometimes make her seem intimidating.
- Cruel and Unusual Death: Executed by being sent out into a snowy field with a flag, befitting her profession as Winter Guard. However, Monobear appears in a parka, grinning evilly and leveling a rifle at her. He repeatedly fires at her, but Marian gracefully dodges almost all of the bullets. However, one bullet finally hits her leg, causing her to accidentally throw her flag up into the air... and then the flag comes down and impales her to death.
- Official Couple: With Ryosuke. She even gives him a quick kiss on the lips before her execution.
- Rousing Speech: She unexpectedly gives one in Trial One after first Shinya offers to be executed, then Kazuya offers to be executed in Shinya's place. She angrily reminds everyone that they promised to avenge the murder victim, which they can't do if they're dead, are they just going to give up easily because they were wrong a couple times?
- Sticky Fingers: Her Dark Secret is that she used to steal little objects knowing they wouldn't be missed. When confronted by this in Monobear's motive, she immediately confesses.
Super High-School Level Itamae
Vain and haughty, Mimi was born into a very traditional Japanese family, who instilled proper views into their child from a young age. Despite her mother's wishes for her to become a maiko, Mimi insisted on working with her father, despite the fact that it was frowned upon for a woman to work in the kitchen. The sixth victim of the mutual killing game, killed by asphyxiation.
- Agent Scully: Never mind the whole being trapped in a spa by evil robotic stuffed animals or any of the other weirdness and horrors she's been subjected to. Mimi outright refuses to believe in spirits and possession.
- Berserk Button: Don't tell Mimi to her face that you think less of her for being a woman, whether in general or because you think the "Itamae" profession should be restricted to men.
- Daddy's Girl: Enough to take up her father's profession as an Itamae.
- Everyone Has Standards: Mimi can be haughty and arrogant, but when she sees the manner in which the chapter 4 murder victim was killed, she calls the murderer cowardly, repulsive, and despicable. Why was such an act of treachery necessary, when the victim was already a weak girl and easy to overpower in the first place?
- Heroic BSoD: Following Ritsuka's execution. It takes several days before she ventures out of her room again.
- Intelligence = Isolation: Mimi was never very popular among her peers, since she is arrogant and aloof.
- Jerkass Has a Point: Takes the mutual killing game very seriously, and isn't afraid to point out that trusting others in such an environment can lead to disaster.
- Lonely Doll Girl: She was this as a child; she didn't mind being unpopular among her peers since she could play with her dolls instead.
- Love Epiphany: Mimi finally realizes that her feelings for Ritsuka are love only after Ritsuka's already kissed her. Amusingly, it is not accompanied by any epiphany that Ritsuka, whom she thinks is a man, is actually female.
- My Girl Is Not a Slut: This is why Mimi's mother wanted her to become a "maiko"; Mimi's mother believes that modern women lack self-respect or any sense of right and wrong, and are willing to bare their flesh like their flesh is something for the autumn wind to batter about. Meanwhile, Mimi is different since her mother made her wear much less revealing clothing.
- My God, What Have I Done?: Mimi indirectly helped Ritsuka and Yukiko get fingered as possible culprits. When the vote turns Ritsuka's way, and Monobear declares that they are about to execute an innocent Ritsuka, Mimi feels horrible because she has sentenced the one person she cared for to death. Amusingly, the seriousness of her remorse is mitigated somewhat by the fact that she still thinks Ritsuka is male.
- No Sympathy:
- To the murder of Kyo in chapter 3's trial. She had despised Kyo, and might even have murdered him herself if there had been a stronger motive.
- Also no sympathy to Kanon, after she turns out to be Kyo's murderer. When a spirit claims to have possessed Kanon and thus to be the true culprit, Mimi believes Kanon is merely lying to get out of punishment, making up a "pathetic" sob story, and Mimi thus gives Kanon an angry speech about fooling everyone and how she should just atone for her crime with a well-deserved execution. She even makes a point about how even though Kyo was a "hog", he at least deserves to have his death be atoned for.
- Not Helping Your Case: Her reaction when accused of being the murderer in Chapter 4. More precisely the way she treats somebody trying to defend her.
- Official Couple: With Ritsuka, so she doesn't take it well when the innocent Ritsuka is incorrectly voted as the culprit in chapter 4.
- Pet the Dog: For all her prickliness, she helped Larry with his injuries after discovering them following the second trial.
- Picky Eater: A necessary trait for her to have, actually, since it improves her palate and lets her prepare better food.
- "The Reason You Suck" Speech: Fully capable of telling anyone at a moment's notice just how much she feels they suck, at length. Normally while keeping a serene expression.
- Speak Ill of the Dead: Jeers at Kyo Otonomiya's corpse after their murder is discovered.
- Stay in the Kitchen: A weird inverted example: her mother wanted her to be traditionally feminine and not work in the kitchen, but she insisted on taking up her father's profession as an Itamae to prove that women could cook in a Japanese kitchen and not ruin the food.
- Supreme Chef: But unlike Teruteru Hanamura, her SHSL talent is not "Chef" or "Cook" but "Itamae", so she's only a supreme chef if she's in a Japanese kitchen specifically.
- Tranquil Fury: She generally keeps a straight face while tamping down her anger, attacking others with barbed words.
- Ungrateful Bastard: During Chapter 4's trial, Arisa tries to defend Mimi by stating she wasn't strong enough to kill poor Renee. Mimi takes this as a personal slight and slings some papers at her would-be defender's head before going into a Tranquil Fury.
- Yamato Nadeshiko: Borderline. She's graceful and conducts her work with great poise, she's devoted to her family (or at least her father), her speech is delivered in polite diction, she's devoted to a traditional Japanese profession, she dresses in traditional Japanese clothing, etc. The "borderline" part comes into play because she is neither submissive nor usually very nice.
Super High-School Level Poetess
A polite and charming young lady who prefers to keep herself out of the public eye. She was born into a highly prestigious family, and her works have become well known around the country, although her name has not. The ninth victim of Doubt Academy White, killed by asphyxiation.
- Eagle-Eye Detection: Very meticulous with an eye for detail.
- Reclusive Artist: Her poems are famous, but she is not. It's common for people to know her poems but not her name, and she prefers it that way, keeping herself out of the public eye.
- Unishment: Monobear's third "motive" is simply to remind the students that if no killing occurs, they will spend the rest of their lives trapped here, instead of chasing their bright futures. But Mitsuko considers the motive to be this trope, since as she sarcastically muses to herself, "Oh, how awful! Being trapped in a beautiful and luxurious resort! What a horrific life we will lead...!"
- Yamato Nadeshiko: She has a reputation as a "perfect young lady" due to her charming behavior.
Super High-School Level Astrologist
An enthusiast who claims to be able to see everything about a person in the stars, simply by knowing their birthday. He is often mistaken for some kind of cult leader. Survives to endgame.
- Almost Out of Oxygen: During chapter 8's morgue investigation with Chris and Hisae, Naoto passes out due to lack of proper ventilation in a room on fire.
- Awesomeness by Analysis: He has the ability to "theorize from many different angles", thanks to astrology giving him an open mind.
- A Hero Is Born: He claims his birth was the product of "three miracles in succession".
- Nervesof Steel: Has remained calm throughout all the trials, never blowing up at anybody. In chapter 4 in particular, Naoto stepped up to gather a lot of evidence. His nerves finally took a hit when he found out that he had been instrumental in setting up a Mastermind vote that voted for the wrong person.
- Nice Hat: Wears a sailor's cap in his profile picture.
- Official Couple: With Jaejin, until Jaejin is murdered in chapter 7.
- The Rival: Eventually becomes this to Eiji. There's no real personal event that sets it off; they just frequently make opposite decisions and eventually can't stand each other. Surprisingly, this does not result in either of them killing the other; in fact, they both survive to endgame.
- Send in the Search Team: With Chris and Hisae. During chapter 8, Naoto brought Hisae and Chris together to search inside of a secret room in the morgue to look for clues about the Mastermind. Things didn't go as planned, however, when Chris activated a tripwire that in turn started a fire. The search ends with Naoto and Chris unconscious and a blubbering Hisae.
- Sherlock Scan: Can accurately read others' personalities based on their birthday, or if he doesn't know their birthday, on his own average intuition.
Super High-School Level Ballerina
Renée was introduced to ballet at a young age due to her mother, a world-famous ballerina. When her mother retired due to injury, Renée quickly proved herself even more skilled and she had been. She generally performs solo, without a company. She's the chapter 4 murder victim, killed by evisceration.
- Abusive Parents: Implied. A talentswap AU on her journal features her mother constantly berating her for not having enough skill to become a dancer, and deriding her when she discovers another talent. During the third trial, she has a Flashback to somebody calling her a 'stupid, useless girl', and nearly responds automatically with "Yes mama, I'm sorry."
- Career-Ending Injury: Not her, but her mother, Noémi, who used to be a world famous ballerina before an ankle injury forced her to retire (and put her in a wheelchair to boot).
- Child Prodigy: Renée has always been excellent at ballet even when she was a child.
- Cruel and Unusual Death: Her murderer posed her as if she was dancing, with her hands tied up over her head... and then savagely beat her and ripped her intestines out.
- Dull Eyes of Unhappiness: Not a major example, but Renée's sprites are always drawn with really dull-looking eyes, as if she's always really tired.
- Hearing Voices: It seems to be her mother, who insults her and tells her to stop being weak and kill someone, especially when Renée is stressed.
- Oblivious to Love: It takes Renée a long time to figure out that Larry is flirting with her. When she does? Cue the Crush Blush.
- Omniglot: Because of her travels around the world, she is fluent in English, Japanese, and French, and at least pretty good at several other European languages.
- Precision F-Strike :In the afterlife, when the survivors are contemplating their Sadistic Choice, Renée screams at the living students, twice, that she and the rest of her classmates are not fucking dead!
- Punny Name: Renée's last name is French for small.
- Stage Mom: Minor example; Renée has been a member of several companies, but the arrangements never lasted long because her mother was never satisfied with them.
- Strong Family Resemblance: Renée is a ballet prodigy, just like her mother was, and she's world-famous, just like her mother... but in her profile Renée is actually described as being better at ballet than her mother ever was.
- Surpassed the Teacher: Well, surpassed her mother anyway. Renée's mother used to be a world-famous ballerina, and now her daughter is a more skilled ballerina than she is.
- Switch to English: Renée employs this trope a lot, as she feels more comfortable speaking English than Japanese.
Super High-School Level Samurai
She gained her samurai skills in her family's dojo at a very young age. Her tomboyish, rough-and-tumble attitude is hidden by her family's strictly traditional etiquette. She feels pressured to succeed so she can meet her family's expectations and not be overshadowed by her two successful older siblings. Tragically, she was falsely convicted of Renee's murder.
- Acquitted Too Late: The first instance of a living classmate being falsely charged with murder.
- Bait-and-Switch: Her execution. It's set up so she, and therefore the audience, believes that the "method of execution" is whatever horrible monster is chasing her. Actually, she's executed by swords that pop out of the floor and wall. So what was chasing her, then? A remote-controlled toy car with a megaphone attached.
- Beauty Is Never Tarnished: When Ritsuka aggravates Larry over him being so upset by Renèe's death, she receives a strong punch to the jaw from the boxer. When Mimi finds Ritsuka afterwards, she states, despite the bruise, "with such beautiful lines that if she didnt know better, Mimi might think Ritsuka resembled a woman."
- Cruel and Unusual Death: Chased barefoot across a stage littered by sharp pieces of glass before being impaled on multiple katanas that slide out from board in the floors and wall.
- Daddy's Girl: Her father trained her in the samurai arts.
- Face Death with Dignity: Despite her false conviction, she gives an inspiring speech to her classmates, saying she doesn't blame her classmates for getting it wrong. She's angry about being judged, but only in an impersonal sense, and not that it's her classmates doing it.
- Half-Breed Discrimination: Ritsuka keeps her half-Korean heritage a secret not because she's ashamed of it, but because she worries about how others will react.
- Lady Looks Like a Dude: In fact, there isn't a single character in the class that has realized that Ritsuka is a girl.
- Official Couple: With Mimi. She even gives Mimi a chaste kiss on the cheek, and after telling Mimi not to cry and that someone could be falling love with Mimi's smile, Ritsuka gives Mimi a kiss on the lips before being executed.
- Sibling Rivalry: Ritsuka feels overshadowed by her older siblings, resulting in her pushing harder for success.
- Tomboyish Name: Ritsuka is an androgynous name in Japanese, as is her shortened name of Ritsu, only adding to the confusion surrounding her gender.
Super High-School Level Sports Fan
Growing up watching his father love soccer, he eventually encouraged him to try out for a team. Though his dad wasn't very good at first, his son supported and encouraged him to keep trying, and he's become a world-famous player who credits Ryosuke's unwavering support for everything. Survives to endgame.
- The Cheerleader: His SHSL talent is to cheer people on, but it's exclusive to sports.
- Heroic BSoD: After Marian is executed, Ryosuke's usual enthusiasm is no where to be found. It even led to having his outfit changed to a rather simple black hoodie.
- No Indoor Voice: A deliberate example; he trained his voice to be really loud so he could make himself heard over an entire stadium.
- Official Couple: With Marian, though he wonders what on earth he did to deserve her affections since he wasn't able to help her. When Marian is set to be executed, Ryosuke promises that if he ever gets out of this place and meets his father again, he'll tell his father that he met someone he cared about as much as his father cared about his mother.
- Precision F-Strike: His reaction to Renée's death. Which was unusual, considering the fact that he wasn't one to swear ever at all.
- Missing Mom: It seems that he has little, or no recollection of his mother ever having any thing to do with him.
- The Power of Trust: His entire SHSL talent is to be able to motivate sports players to become superstars just by being their fan.
- So My Kids Can Watch: His SHSL talent is to invoke this; his soccer star father performs his best on the field because he knows Ryosuke will be watching and cheering him on.
Super High-School Level Hitman
Born into a life of organized crime, Shinya was a young prodigy within his family until an accident convinced him to quit and pursue a more respectable life style. He's the chapter 2 murder victim; someone slices him and he dies from loss of blood. In a private conversation with Yukiko, Adeline reveals that she was the one who killed him.
- Child Prodigy: Shinya proved to be one of the most promising in his field to show that, if he wanted to, he could become one of the best through determination and ruthlessness.
- Determinator: Never one to shy away from any confrontation or obstacle, Shinya faces them head-on regardless of his odds or the consequences that might follow. Not that it helps, since he's murdered in chapter 2.
- Eagle-Eye Detection: His eyes are honed to the point of identifying objects and individuals at great distances. One of his skills.
- Family Honor: His father and family in general take honor quite seriously. Shinya used to as well until a certain incident changed his mindset. He no longer thinks the occupation to be honorable and considers it to be nothing more than murder.
- Hidden Heart of Gold: Enough of a heart to voluntarily quit his SHSL talent and try to pursue something more respectable.
- Hitman with a Heart: As much as it could be possible, in the least. Shinya takes no satisfaction in the act of taking another's life. When he does, he makes sure to do so quickly and even prays for their better fortune in another life.
- I Am Not My Father: His father being one of the most infamous and well-known hired guns in the yakuza, has been a role-model for Shinya for quite some time. Until a certain incident occurred which convinced Shinya to stray from his first intended path.
- I Like Those Odds: He has discovered a certain fetish where he loves to take chances. The greater the risk, the greater his satisfaction. There is no gamble that he would shy from, although if there is nothing to be gained there would be no purpose in it at all and he understands this.
- Innate Night Vision: His eyes are incredible in that they can quickly adjust to dark environments to easily identify silhouettes. One of his skills.
- Mythology Gag: His slit throat is unusually similar to the way Koemi was killed in the previous murder.
- Official Couple: With Kanon in the afterlife, though this wasn't revealed until Doubt Academy White was over and the "dead students blog" was opened to the public.
- Zero-Approval Gambit: Shinya attempts to pull one in chapter 1's trial: he feels the real murderer was justified in killing because they were afraid of what would happen if they didn't, so Shinya, believing himself more deserving to die due to his SHSL talent of being a Hitman, deliberately attempts to get himself executed in the murderer's place, since he feels that would still mean someone more deserving than he would get to live.
Takahiro 'Hiro' Hirano
Super High-School Level Choreographer
Hiro has traveled all around Southeast Asia, perfecting different styles of dance. He deals primarily with idol and pop groups, and is best known for his hip-hop group BULL3T, which gained popularity on the internet. He's easygoing and optimistic, as well as flirtatious and slightly narcissistic. Physically assaults Monobear after his takeover and is killed as a result.
- Death by Irony: His dance troupe's name is BULL3T and Monokuma kills him by riddling him with bullets.
- The Fellowship Has Ended: Takahiro's group has apparently broken up, and if we can trust Monobear's word, it was Takahiro's fault.
- It's All My Fault: His reaction to ending up in the afterlife in the "dead students blog" that wasn't revealed to the public until Doubt Academy White was over. Takahiro feels that it was his own hot-headed nature that got him killed, which is fitting considering his mother once told him that his erratic behavior would be the death of him someday.
- Narcissist: Has layers of this underneath his laid-back and optimistic attitude. We never get to actually see him behave like a narcissist, however, because he pisses Monobear off before the mutual killing game even begins, and Monobear riddles him with bullets. In fact, while he's the very first person to die and thus the very first person to enter the afterlife, throughout the entire afterlife blog he seems to have dropped this trait entirely. He spends the entire dead students blog attempting to comfort the others and rally them around.
- Official Couple: Becomes this with Fumiko in the afterlife, although this wasn't revealed until Doubt Academy White was over and the "dead students blog" was opened to the public.
- Omniglot: He was born in Seoul, South Korea; spent some time in Los Angeles, California; and now lives in Japan. So now he's fluent in Japanese, English, and Korean.
- Shut Up, Hannibal!: In the afterlife, Takahiro finally gets sick of Mimi's "prideful bullshit" and tells her off, reminding her that now that she's dead, she's just as unimportant in the grand scheme of things as everyone else.
Super High-School Level Voice Actress
Despite being born into a family of actors and actresses, Tomiko proved to be rather camera-shy, and so chose to pursue voice-acting instead, and has had a prolific career. Despite her calm demeanor, Tomiko has been quite sheltered for most of her life. In chapter 8, she gets herself executed in Larry's place for reasons that are not revealed... in vain, because afterwards Monobear executes Larry anyway.
- Anguished Declaration of Love: After Monomi tries breaking the news of Kazuya's murder to her in the worst possible way — by showing her the picture from his Monobear file — Tomiko tries dismissing it as a joke and tells her how she's figured out she's in love with Kazuya.
- Cruel and Unusual Death: In a shocking twist, Tomiko tries to get herself executed in Larry's place in chapter 8. Tomiko is executed by being placed in the "voice acting role" of a villain who deserves to die, and the robotic heroine of that show shoots her through the heart, killing her instantly.
- Innocent Inaccurate: After chapter 6's trial, after Tomiko enters the elevator, she passes out and doesn't wake up until the next chapter's trial is already over, meaning she slept through most of chapter 7. When she wakes up, she asks Monomi if Monomi can please bring Kazuya to Tomiko, not being privy to the fact that Kazuya is one of chapter 7's two murder victims.
- Love Confession: In chapter 7, as Tomiko is talking to Monomi upon waking up from having been passed out, Tomiko blushes and confesses that she loves Kazuya, so could Monomi bring Kazuya to Tomiko? Well no, because Kazuya had previously been murdered.
- Only Sane Woman: Shares this status with Naoto. Tomiko's remained calm throughout all the trials, and in the chapter 4 trial in particular she has expressed annoyance that her classmates keep getting into fights and arguments. She's one of the few classmates so far who has never been shown shouting, or with an unusually angry expression, or threatening another classmate, or some combination of the above.
- Sailor Fuku: She's wearing a white and pink sailor fuku in her profile.
- Senseless Sacrifice: In chapter 8, Tomiko attempts to sacrifice herself to be executed in Larry's place. But after Tomiko is executed, Monobear adds a cruel twist by doing a second execution, and executing Larry anyway.
- Shrinking Violet: She belongs to a family of regular actors and actresses, but Tomiko herself is "camera shy" and thus chose to become a voice actress instead.
- Spoiled Sweet: Described as "sheltered" with no idea how the world really works, but takes a genuine interest in others' day-to-day-lives as a result.
- Tender Tears: While apologizing to Ritsuka in chapter 4, believing herself to be foolish, naive, and worthless for inadvertently having contributed to the innocent Ritsuka being voted as the culprit. Tears roll down her eyes as she claims that she is no better than the culprit, for having brushed Jaejin aside even though Jaejin was right about the culprit not being Ritsuka.
- Yamato Nadeshiko: Has a reputation for having a calm, mature personality, but in reality is a very sheltered individual.
Super High-School Level Chemist
Tomoe started her career by improving her late father's formulas, but soon started forging her own paths and becoming famous in her own right. While her father's work in environmental science started her in the field, she chose the path of a chemist instead. Responsible for murdering Hidehisa, and was correctly pinned as the culprit during the ninth trial.
- Birds of a Feather: She and Arisa, the other scientist, get along well.
- Cruel and Unusual Death: Monobear uses a shrink ray to shrink her down small enough to fit in a glass beaker with a bit of sodium in it. Then he pours a small bit of water into the beaker, which falls onto the sodium and causes a chemical reaction that causes the sodium to explode, taking the trapped Tomoe along with it.
- Follow in My Footsteps: Started to follow in her father's footsteps of environmental science as she did an experiment to purify contaminated water, but ultimately chose to become a chemist instead since she got more interested in how substances interacted.
- Sympathetic Murderer: After being pinned as the culprit, Tomoe reveals that she had been afraid of dying ever since Renée's body was found and killed Hidehisa only because he attempted to murder her first, leaving her to strike out in self-defense. While she admits that she could have let him live, she contends that he could have tried to kill her again if left alone.
- Throw It In!: One of her skills, actually; if she can't find exactly what she needs, she's very good at improvising something else she can use that'll work.
Super High-School Level Mangaka
Yukiko's manga career started after winning a contest in a popular magazine. Her family then reluctantly agreed to allow her to write manga, provided that she used an alias. Antisocial and stone-faced, Yukiko comes off much harsher than she actually is. Following Jun's blinding/punishment, Yukiko cuts out one of her own eyes. She is responsible for murdering Renée but escaped execution after Ritsuka was voted for in her place. She later murders Kazuya Hirayama and is correctly pinned as the culprit during the seventh trial. Unfortunately, she was also falsely accused of being the Mastermind during the same trial, and their first vote was spent only to prove her innocence.
- Acquitted Too Late: Despite all the suspicion, she was not the Mastermind. In a brutal twist of Irony, the first Mastermind Vote proves her innocence shortly before her scheduled execution for murdering Kazuya.
- Ascended Fangirl: She became a SHSL Mangaka after first becoming a fan of Junji Ito's Uzumaki, and then winning a popular manga contest, which caused publishers to pick her up and her to become a successful mangaka.
- Beauty Mark: Under the corner of one eye.
- Berserk Button: Mimi punches hers with her Speak Ill of the Dead moment and gets slapped for it.
- Bunnies for Cuteness: As her hair clip shows, she likes rabbits. She even thinks Monomi is cute. Following Chapter 3, she starts wearing a Monomi eyepatch, and claimed Kanon's stuffed rabbit.
- Cruel and Unusual Death: Her execution involves a large Monobear dressed like the Queen chasing her into a rosebush maze with an axe, and then he makes Yukiko think she's lost him... only to reappear cornering Yukiko in a dead end, and finally cutting off Yukiko's head.
- Expository Hairstyle Change: In the afterlife, Yukiko's hair has changed from black to white, although this wasn't revealed until Doubt Academy White was over and the "dead students blog" was opened to the public.
- Hidden Depths: Part of the reason her mangaka abilities are SHSL is the fact that she's not just great at drawing, she's great at writing, too.
- How Dare You Die on Me!: This is her reaction to discovering that chapter 3's murder victim is Kyo, since Kyo had earlier promised to teach Yukiko how to live for herself and find her own happiness.
- Important Haircut: During Chapter 5's Abnormal Days, she cuts her hair to about shoulder length as part of a makeover.
- Nice Job Breaking It, Hero!: By successfully convincing the others that Shinya killed himself, she inadvertently caused Jun's blinding.
- Official Couple: Subverted with Kyo. Monobear makes an off-hand comment about how selfish it is of Yukiko to hide away her "passionate necking" with Kyo. What actually turns out to have happened is that Kyo kissed Yukiko after they bonded over similar backgrounds, but then Yukiko left in self-disgust to meditate on her feelings for Jun.
- Off with His Head!: She's executed in an Alice in Wonderland parody with Monobear-as-the-Queen cutting her head off with an axe.
- Red Herring: She's an excellent "Mastermind" candidate. She's emotionally unstable, she's rude to the others, and in chapter 4 Monobear even makes Yukiko wear red-and-white-and-black, the colors of a traditional Dangan Ronpa mastermind, complete with a friggin' Monobear eyepatch just to complete the "duality" look...nice try, because as Naoto found out the hard way when pushing for a vote, Yukiko is actually not the Mastermind.
- Red String of Fate: During Chapter 4's Trial, she reveals the red string she started wearing around her neck is a reference to this, as a memorial to Shinya.
- Sanity Slippage: Because cutting out your own eye and giving it to another person as a threat usually doesn't bode well for one's general mental state.
- Sugar-and-Ice Personality: Even her profile explains that she has a soft interior though being outwardly emotionless.
- Super OCD: Which helps her be very detail-oriented as she's drawing manga, but sometimes it can make her a control freak regarding her projects.
- Tragic Keepsake: Kanon's stuffed rabbit.
- Unlimited Wardrobe: Has several different distinct outfits.
- What Did I Do Last Night?: Yukiko does not remember killing Renée at all, as a result of the brain damage she inflicted on herself when she took out her eye. She only realizes that she was indeed Renée's murderer after her own death.
- Why Couldn't You Be Different?: Downplayed example, but her parents were initially against her being a mangaka, but then relented as long as she promised to publish under an alias so as not to "dirty the family name".
The MastermindThe traitor responsible for Monobear's Deadly Game, aka Katsuya Matsushita. Member of the Doctrina Artifice, a group opposing The Collective — the group responsible for sending them all to Bright Side in the first place.
- Big Bad Friend: During a meeting, the Mastermind counters Monobear's concern about having 'hormonal relations' by claiming it just makes the others trust them more. This heavily implies they're very close to at least one of the others, or at least believe themselves to be.
- Big Brother Is Watching: Planned to use this against The Collective, broadcasting the footage of what happened at Bright Side to the world to expose their corruption and cruelty.
- Cruel and Unusual Death: Chased by a Mono-dog, ankle mauled and broken, then carried on a moving walkway towards a massive printing press, which crushes him.
- Red and Black and Evil All Over: A very notable aversion: unlike the Masterminds in Doubt Academy 1 and Doubt Academy Black, the Doubt Academy White Mastermind does not pull this kind of costume switch. In fact he doesn't pull a costume switch at all; instead, he switches to Mastermind with his expression instead, his hair flying everywhere and making an "evil crazy face" with lots of sharp teeth and a manic grin.
- The Revolution Will Not Be Civilized: Doctrina Artifice is fighting against The Collective by setting up the mutual killing game among a bunch of The Collective's human guinea pigs.
- Well-Intentioned Extremist: In his eyes, the mutual killing game was necessary to help showcase the depths to which The Collective would sink.
- You Have Outlived Your Usefulness: Monobear, working as part of the Doctrina Artifice, is perfectly willing to execute him as further example of The Collective's evil. Katsuya was not aware of this, thinking he'd be allowed to return home.
