Koharu's Description:
Member of the Supplementary Lesson Department of Trinity General Academy.

Originally, she belonged to the Justice Task Force, but her grades fell and she fell into a crisis of repeating a year and was forced to transfer to the remedial class department. She thinks she is an elite, but in reality, she is too stupid to keep up with her schoolwork. She has a hobby of collecting lewd magazines, and is often embarrassed to be alone with her fantasies about even the most trivial things.

Personality:

Koharu is a naive and delusional young girl with a good heart, while her skills allowed her to become a part of the Justice Task Force. However, because of her stupidity and delusional behavior she is often set back.

Because of her delusions, she would believe that Sensei has sexual fantasies towards her that she denies having. However, beneath it all she is a dependable person who provides lighthearted banter and a springboard to bounce off of for the Supplementary Lesson Department.
