Nishina Eri

A girl who has a complex over her boyish appearance and manners and wishes to be more feminine. However, she has to constantly worry about the image she gives off to others, and as such acts more boyishly. After finding out a certain secret about her, Eri's best friend betrayed her, and she was sent to Seiren Gakuen as a result.

She actually went to the same school as Yuria, but the two never talked to each other. Eri had been interested in Yuria even before coming out, and after meeting her again at Seiren Gakuen, assumes they are two peas in a pod, doing her best to befriend Yuria immediately.

Eri is also bad with men, but uses the masculine pronoun "boku" to address herself.
