Super High School Level Wedding Planner

- CPR: Clean, Pretty, Reliable: Averted. It's attempted on him immediately after his death, but not only does it fail to restart his breathing or heartbeat, but the untrained, desperate motions break several bones in his chest. The fact that someone even tried this becomes very important in narrowing down the suspects.

Super High School Level Maknae
- Idol Singer: Though Jaejin was once part of an eight-member idol group, he appears to be focused on solo projects at the time of the game.

- Previous Player-Character Cameo: Jaejin previously appeared in Doubt Academy 2: White.

Super High School Level Electronic Musician
- Blackmail: She discovered her family's company was deeply corrupt and blackmailed her parents with that information so that she'd be allowed to pursue her own career choices.
- Cruel and Unusual Death: She's thrown into a crowded dance floor and made to struggle onto an empty, open stage, which collapses around her to reveal that she's standing on a conveyor belt. Jaz is dragged off to a quality control line, where her family watches as she's inspected, labeled as defective, and electrocuted to death.
- Deadpan Snarker: Her sense of humour, both her own and what she finds funny, is noted as being 'dry wit and sarcasm'. She can sometimes come off quite blunt due to this and her own personality.
- Do Not Call Me "Paul": She prefers that people call her Jaz or some variation of it, but is very uncomfortable with her full name, especially use of her surname.
- Family Business: An electronics distribution company, though Jaz's public bio states she decided against joining it to become a musician.

Super High School Level Cosplay Idol
- Break the Cutie: The cycle of distrust and failures of justice wear Kaya down greatly, the final straw being the execution of a close friend.
Super High School Level Culinary Competitor
- Abusive Parents: His biological parents subjected him to a severe case of Parental Neglect by leaving him alone for extended periods of time in an unsafe home, resulting in him nearly dying in a house fire. While Kenichi's in better custody now, it's implied that he continues to face Financial Abuse from his birth mother whenever they communicate.
- Accidental Murder: Through Kenichi's negligence, Daisuke ends up consuming a fatal dose of poison.
- Alliterative Name: Not just him, either, but also his mother Kazue Kagata.
- Career Versus Man: It's pointed out that if he's working at a restaurant or away on a long-term filming commitment, Kenichi might not have any time to spend with loved ones, especially since with the former he's expected to work on days couples would usually be eating out. He's willing to let go of romances if they aren't happy with this arrangement, though, rather than letting their disappointment grow into resentment.
- Child Prodigy: The focus of Chef Search Juniors was a whole group of prodigies ranging from ages eight to thirteen that could cooking with just as much skill and finesse as professional adults, and at eleven Kenichi was named the best among them.
- Cooking Duel: A literal application of this trope. His talent revolves around contests of culinary skill, complete with televised appearances on fictional equivalents of real-life shows.
- Cruel and Unusual Death: Kenichi is locked in a cage suspended over a fire, about to be cooked. Though he manages to escape, the floor gives way and he falls into a mincing machine. His bloody remains are then turned into a shepherd's pie.
- Hypocrite: Kenichi continues to resent Siyu even weeks after he sacrificed Haruka to save his own life, believing him to be little more than a coward. When Kenichi finds himself cornered in trial and facing that same fear of impending death, his last-ditch attempt to redirect attention is to throw Date under the bus and accuse him of killing Hikaru. A lot of characters call him out on this.
- Named After Somebody Famous: His given name comes from Chen Kenichi, the only Iron Chef to stay on the original Japanese run from beginning to end. His surname comes from Kagata Kyoko, the first woman to compete on the show, and the youngest chef to emerge victorious after she defeated Chen at the age of 26.
- Not So Different: Kenichi ends up doing the same actions that he openly and loudly denounced Siyu for, and this in turn destroys a lot of the respect his class might have had for him. Kenichi acknowledges this and makes an offhand remark about apologizing if he has a chance to see him.
- Raised by Grandparents: The specifics aren't stated, but it's noted that was adopted by his grandparents, and that he denies any notion that they aren't his "real parents".
- Scars Are Forever: Much of the right side of Kenichi's body is scarred from severe burns he got as a child; while surgeries were done to restore function and appearance as much as possible, there's still some scarring remaining on his face and especially on his arm.
- The Southpaw: It's mentioned that he has some trouble working with kitchen tools made with right-handed people in mind, but he's found small ways to cope with each tool.
- Trash of the Titans: Not Kenichi, but his biological father, who had hoarded books, magazines, and newspapers during the time Kenichi still lived with him; rather than the usual lighthearted application of this trope, it was a serious safety hazard that almost got Kenichi killed. Rubbing it in further, one of the Monomachine items turns out to be an overstuffed box taken from his childhood home, complete with a reminder of said near-death.
- Why Did It Have to Be Snakes?: Kenichi has a fear of feeling trapped, which becomes steadily worse over the course of the game and even leads to him being incredibly uncomfortable in elevators. And that's not even getting into the fact that his execution shoves him into a locked cage.
- You Gotta Have Blue Hair: It's his natural color, too, and he's not the only one in his family; one person is stated to have had blue-violet hair, for example.

- They're Called "Personal Issues" for a Reason: After figuring out that Yona has her secret motive card, Setsuna panics and does nothing to reply to the storm chaser's question.
- Unknown Rival: Unbeknownst to Setsuna, Tobio considers her his mortal enemy.

Super High School Level Thereminist
- Big Sister Worship: Holds her older sister, Kotone, in extremely high esteem, to the point where she's the only person the egotistical Shion ranks above herself in importance and will automatically defer to.
- Emotionless Girl: Slides into this, complete with a Creepy Monotone and the occasional Dull Eyes of Unhappiness when under a great deal of emotional distress. According to Shion herself, this is how she 'truly' is beneath her egotistical facade, although her self-perception may be off.
- Family Theme Naming: Everyone in the Tsuzuki family has sound/music-based names.
- Gratuitous English: Frequently. Shion believes it makes her sound more erudite and sophisticated, but all it's done so far is get her made fun of.
- Height Angst: Shion's lack of height (she's 5'3") is a large source of annoyance for her, to the point that she regularly wears lifts in her shoes in order to appear taller.
- Inferiority Superiority Complex: While Shion initially presented as being unconditionally in love with herself, she begins showing flashes of this instead as the game goes on, usually when something doesn't go the way she wanted it to go. By the time the third trial rolls around, it's become clear that her usual egotistical act hides a truly immense amount of self-loathing.
- It's All About Me: Incredibly self-centered, constantly placing her own needs and desires above those of everyone else, with her older sister being the sole exception to this rule. She also enjoys making a great deal of noise about how awesome she is, at least most of time.
- Lethal Chef: As expected from someone who had never cooked a day in her life prior to the start of the game. Pretty much everything she attempts to cook ends up partially carbonized.
- Mad Libs Catchphrase: "____ is one of my thousands of skills!", with ____ usually referring to whatever she's doing at the moment or has been asked to do.
- Meaningful Name: One note she has directly played off of at least once, referring to herself as "the player of the poetic song that weaves throughout the old capital."
- Photographic Memory: A variation - she possesses absolute pitch, allowing her to identify any sound that has reached her ears before based solely on its associated tone.
- Rich in Dollars, Poor in Sense: Ridiculously wealthy, rather deficient in conventional wisdom.
- Sheltered Aristocrat: Although shell try to downplay it, Shion's sheltered and privileged upbringing has left her woefully ill-prepared for a number of matters, to the point of leaving her completely clueless about how to do simple household chores.
- Something About a Rose: Possesses a strong affinity for them, as anyone who steps into her room will discover.
- Stepford Smiler: Shion at least feels herself to be the "empty" variation of the trope, often referring to herself as cold and hollow beneath her constructed facade in narration.
- Took a Level in Jerkass: Shion was never a wholly pleasant person, but she has become noticeably more vindictive and prickly by the time the fifth trial rolls around, which is rightly called out by several other students.
- Trademark Favorite Food: Cheese, especially the pricier varieties.
- What Is This Feeling?: Shion isn't used to forming emotional attachments to anyone who isn't her sister and is therefore both confused and frustrated by the genuine distress that the week 4 case, which ends with the deaths of two people she had grown attached to, ends up causing her.
- Why Did It Have to Be Snakes?: Shion is decidedly uncomfortable and on-edge in the presence of intoxicated people due to past experiences, as revealed during the chapter 2 trial. She is also mentioned as possessing a fear of both insects and arachnids early on. Naturally, both of these end up on full display during the chapter 3 motive.
Super High School Level Lion Dancer
- Cloud Cuckoo Lander: Appears to think that Monobear killed Jaejin and generally acts in a cloudcuckoolanderish way.
- Meaningful Name: "Siyu" can be read as "Thinking of the World" - fitting for someone who tries his best to look after everyone and ensure their safety. Subverted after his actions result in Haruka being executed, but it genuinely seems that he's upset over his actions.
- Nice Guy: Very kind and considerate to everyone he meets. Subverted after his actions result in Haruka's execution, doubly subverted... sort of after he goes on a quest for redemption.
- Unusually Uninteresting Sight: He shows up to the investigation and first trial dressed as Emiko Shiromura from Doubt Academy Alpha, complete with purple face paint and makeup, and nobody appears to comment on it besides in internal monologue.

- The Perfectionist: If he messes up at anything, he won't just correct his mistake, he'll start the task over completely.
- Together in Death: Subverted. Though Si-Hoo and Tobio both die in their respective games and subsequently become an Official Couple, it turns out that the "living" kids are trapped inside a virtual reality world, and the dead kids have actually just woken up in the real world.
- Unknown Rival: Unbeknownst to Setsuna, Tobio considers her his mortal enemy. This changes during the first investigation, though he does lock her in the Ice House, exposing her to the dangerous chemicals used to kill Jaejin. After death, he sheds any animosity he may have felt towards Setsuna, even going so far as to refer to her as "Setsuna-chan".

Super High School Level Esotericist
- Ambiguously Human: It isn't made explicitly clear just what's happening in the second half of Ri's punishment, but between his odd-colored blood, his fast healing, and the fact that he can't be killed with anything short of decapitation, something is clearly off about him.
