Chizuru Minamoto  

, 源 ちずる

Chizuru is a second-year female student at Koutas school who appears to be an ordinary girl with large breasts. However, she is actually a 400-year-old powerful fox deity who transforms her hair from black to blonde when she reveals herself. She frequently hangs around and interacts with Kouta, despite him being the only male she shows genuine affection towards. Chizuru deeply loves Kouta and desires to enter into a "relationship of sin" with him. In the manga, it is revealed that Chizuru and others live in a correctional facility for Youkai. Although Chizuru tries her best to consummate her relationship with Kouta despite facing several challenges, she often forces herself on him without regard for where they are or how he feels about it, resulting in tantrum fits whenever someone else approaches him.
