Aida Yuzuka

Ryuuga's teacher. She loves her students very much but has a hard time controlling her class, especially students like Haruo and Kuraki. Often times Mifuyu is forced to keep the class under order for her. Most of the class calls her Yuzuka-chan.

Because of her timid personality she's the first girl Ryuuga mind breaks and captures her soul. After this she becomes a willing participant in raping the other girls.
