All-Loving Hero: The phrase "wouldn't hurt a fly" was probably meant for him.
The Everyman: Well, kind of. He's a pretty average boy, except for the fact that he's the best boy scout in the area.
Girl Scouts Are Evil: A completely subverted gender-flipped version. Kioshi is compassionate and one of the reasons he's so devoted to scouting is to help others.
Chikaru “Esme” Endo - Ultimate Starlet
Do Not Call Me "Paul": Not only does she resent her first name, she also dislikes it when people use her last name. She prefers the name "Esme" for what she describes as its "foreign glamour."
Famous for Being Famous: She's an aspiring actress, but even she admits that she "spends most of my time socializing with my idols."
Genki Girl: Never runs out of energy, or so it seems.
Glory Hound: Esme often frequents activism events often. When Kioshi asks her about this, she reveals that it's almost solely for the publicity.
I Just Want to Be Special: The only talentless student of the bunch, he often expresses to Kioshi how he wishes he were actually talented. Even when his Ultimate Talent is actually revealed, he still feels this way because his talent has brought harm instead of good to others.
Hanako Hoshino - Ultimate Step Dancer
Former Child Star: Apparently won her first step dancing competition before she was even two years old.
Girly Bruiser: She's very feminine and tough as nails.
Child Hater: "Children aren't my thing. Honestly, they're a waste of space and time."
Only Known by Their Nickname: The only way to find out Sacha's name is to look in the official monopad. Apparently, even his closest friends just call him Sacha.
Akira Koga - Ultimate Painter
Buffy Speak: Often has trouble describing things to her classmates because of this.
Cool Big Sis: She has 17 younger siblings, all who love and respect her.
Wild Child: Deconstructed. He's normally level-headed (if not totally emotionally blank), but if you REALLY piss him off prepared to get clawed or hissed at.
Haruka Matsunaga - Ultimate Mathematician
Academic Alpha Bitch: Her ultimate talent is academic, and her attitude is very similar to this trope.
Girl Next Door: Her easygoing and down to earth mannerisms make her come across as this. To add onto the trope, Kiyomi's room is literally right next to Kioshi's.
Little Miss Snarker: Whenever Natsumi opens her mouth, there's about a 90% chance that she'll say something sarcastic.
Jotaro Ohara - Ultimate Test Subject
The Woobie: Jotaro is a well-meaning and sweet boy who has spent his entire life in labs being tested on, covered in bandages to hide his deformities, and barely allowed to sleep. He's been through a lot, and this is even BEFORE the killing game starts.
Isabelle “Izzy” Izumi - Ultimate Model
Abusive Parents: If you complete her free time events, she'll reveal that being constantly critiqued about her appearance by her mother led her to become a model to feel more beautiful.
Even the Girls Want Her: Izzy is a very desirable character, and not just to the guys of the group.
The Woobie: Jotaro is a well-meaning and sweet boy who has spent his entire life in labs being tested on, covered in bandages to hide his deformities, and barely allowed to sleep. He's been through a lot, and this is even BEFORE the killing game starts.
