Sayaka Watanabe (渡辺 彩花 Watanabe Sayaka) is a college student who is staying at the Kawai Dormitory just like Kazunari Usa. She also loves to get physically intimate with Mayumi Nishikino, such as fondling her breasts.


At first glance, Sayaka is a cute college girl, but she's cunning, smart, and dark when it comes to the way she treats men, often leaving pointed criticisms of Mayumi Nishikino's skill as a "bad man hunter." But on the other hand, she is very affectionate so she loves to hug and cling to people and she has a lesbian side. This has been shown with Nishikino, since she constantly tries to grope her breasts, kiss her and even sleep with her.


Sayaka and Tsuneda Miharu first met in their second year of middle school, it happened when some upperclassman were giving Tsuneda a hard time and she saved her, but what actually happened was that the upperclassman got scared and ran off after they saw Sayaka escape from a shed that she had finished destroying. The reason she destroyed the shed was because she sometimes got locked inside of it when she did wrong deeds, so one day she decided to destroy it.
