Grade: 3rd Year Junior High → 1st Year
Age: 14-15
Personality Traits: Considerate, caring, highly curious, enthusiastic about adult matters
Position: Member of Go Home Club, Member of Judo Club (one day)Kotomi's the cute type—long dark brown hair in twin tails, big brown eyes, and usually wearing a big smile. She dresses way better than her brother on days off, and she's definitely noticed some physical changes since starting high school; her first uniform was apparently too tight in the chest, which she complained about more than once.
She's naturally charming and makes friends without trying. Classmates love her, and she's somehow managed to befriend even upperclassmen like Mutsumi Mitsuba. Suzu once thought she had real idol potential. The thing is, though, Kotomi's also pretty lazy and not exactly book-smart—she needs constant help from Takatoshi or Suzu just to keep up with Ousai's standards. She's got a wild imagination and tends to act like she's the protagonist in some shounen anime.
Her most memorable trait? She's openly, shamelessly into adult stuff—the weirder side of sex included. Like Shino and Aria, she knows her way around galge and pornography references. What makes it awkward is that she'll talk about this stuff anywhere, with anyone, without a filter. Takatoshi and especially her best friend Toki get visibly uncomfortable when she does this.
There's been a running joke about potential incest vibes between her and Takatoshi, mostly because her combination of perverted interests, airheadedness, and constant jokes makes it genuinely hard to tell if she's flirting or just messing around. Nothing concrete suggests she actually has real feelings for her brother, though—it's mostly just comedy fodder.
