Midou Eriko

The music teacher and principal of the academy, she is highly disciplinary to the protagonist.
She is an enthusiastic teacher, but her harshness and scoldings alienate her from her students. She also constantly nag the protagonist due to both being new and male in an all-girls school.

Eriko is a beautiful woman with a well-built face and good proportions, but her personality scares off most men.
Deep down, she felt like she wasted her youth, where she was always serious and has no exciting memories.

She is still a virgin, hopeful her one true love will take it.
