Sumireko Sanshokuin

Sumireko Sanshokuin, usually called Pansy by people close to her, is a librarian committee member introduced with a petite build, braided hair and a gloomy reputation among students. Polite with most peers but sharp-tongued toward Amatsuyu, she is highly observant, academically capable enough to tutor friends and especially strong in classical literature, though she dislikes mathematics.

Pansy deliberately keeps a low profile and compares herself to a chameleon because of the contrast between her public presentation and the person she keeps hidden. She takes a particular interest in Amatsuyu and is strongly infatuated with him.
