Aihara, Kazumi

相原カズミ

She is quiet, mysterious, and somewhat sadistic. She is frequently observed recording details in her observational diary about whatever catches her interest at the moment, instead of joining everyone else in physical activities. However, no one—not even Chika, with whom she has been friends for a long time—has ever seen her laugh. Like Ryouta, she serves on the health committee. Her number on the class list is 1.
