Arisa is a half-Japanese transfer student from Finland who moved to Japan specifically to immerse herself in its culture—particularly the otaku scene in Akihabara. She's best known for her infectious enthusiasm and her surprisingly brutal strength; despite looking like any other student, she's picked up martial arts training from multiple styles and even spent time under a Chinese master's tutelage, giving her the kind of superhuman power that catches people off guard.
She first met Tamotsu Denkigai while hunting for a specific figurine and they clicked immediately—bonding over shared interests and the fact that she could actually keep up with him physically. She's a dedicated cosplayer and genuinely loves the hobby, though it's hard to take her seriously as just a regular person when she can casually throw people around. Matome Mayonaka, another friend in their circle, definitely feels the gap in strength between them.
