緋月 詩乃

A teacher at Akizuki Academy and the older sister of Ayumi and Mitsuna. She is an average teacher and doesn't feel any special passion towards teaching. Still, as a young female teacher she is popular among students. During her schooldays she learned Aikido (has black belt), so she's got self-defense covered. She's extremely direct and harsh with her words. Loves alcohol and drinks a lot, sometimes drinking so much she loses her memory. In the past she has experienced a huge failure, since then, she has put any relations with men on hold.
