Nagoshi Yumi

A dark and shy classmate and one of Rei's cronies.
She is a quiet girl with a plain, petite figure.
She is naturally inclined to be bullied, and has had such experiences in the past, but thanks to the fact that she is liked by Rei, a member of the girls' group, she has been able to get protection.
Perhaps because of this, she has no initiative to adapt to others and rarely asserts herself in a situation.

Perhaps because she is mentally unstable due to her involvement in this incident, she is at the mercy of the protagonist.
