布留見 ちふる

She is a deer-like university student who lives in the neighborhood. She's 19 years old. She and Haruki used to go to school together when they were small children, and they still know each other's names and faces. She has a voracious appetite for sex and is very interested in the male body.

At first glance, she appears mature and calm, but in fact, she has been a serious BL fan since elementary school and is still active as a doujinshi artist as a secret otaku. She is so deeply involved in the otaku world that she creates her own fanzine and participates in events.
