IQ: 180
A first-year genius who got held back and is now 16, serving as Student Council Treasurer. She's easily the most mentally mature person around—her IQ hits 180, and she can do 10-digit math in her head without breaking a sweat. The smartest student at Ousai Academy, no contest.
But here's the thing: she's deeply insecure about her appearance. She still looks like an elementary schooler, which is basically the one topic guaranteed to set her off. The series loves poking fun at her height and childish look, and every single time it happens, she absolutely loses it.
On the flip side, she's terrified of anything paranormal. Ghosts, spirits, the supernatural in general—mention any of it and she'll start shaking and freaking out, which fans often find hilarious given how composed and intelligent she normally is.
