Sugisaki Chiaki

She is an honor student type with a bit of a temper. She has had a slight aversion to men since puberty.

She showed leadership immediately after entering the school and became a class committee member. She has excellent grades, and she is willing to lend a helping hand to any girl (or woman) in need.

She noticed Akemi, who was hiding in the classroom at the beginning of the school year, and actively talked to her. Although it has not been that long since they became best friends, They become each other's (and Akemi's only) close friend in the class.
