Tsutsumi

Tsutsumi is a student who loves cats despite being allergic to them, as shown when she attempted to rescue a cat from a tree despite her inability to climb. Her allergic reaction serves as a warning system to detect when cats are nearby.

She has short blonde hair, blue eyes and wears a yellow hoodie. She is a close friend of Kaoru and is often bullied by a group of three other students.
