森原 木葉

She is the protagonist's classmate and serves as class president, and in that capacity, she often supports Yuko. She is an excellent student and has high expectations from those around her, so she unconsciously forces herself to always behave that way.

She is also very conscious of her appearance and takes the initiative in picking up paper scraps that have fallen on the floor,
showing her obsessive-compulsive side.

She is an excellent student, but she is not good at sports, so she often observes physical education classes under the pretext of feeling unwell or having her period.
