Character from Kimi no Koto ga Dai Dai Dai Dai Daisuki na 100-nin no Kanojo. Aijou Rentarou's fifth girlfriend, and a mad scientist.
She has aqua eyes and short red hair with antenna hair. She looks small due to a failed immortality drug, though it can be reversed for a short period of time using her negation drug.
She wears a lab coat instead of the blazer in her school uniform, revealing suspenders attached to her skirt.
Voiced by Asai Ayaka.
