, 櫻井恵梨香

This individual is highly dependent on sexual activity and allows anyone to engage in intercourse with her. She entered into an arrangement with Kazuhiro where he could serve as her videographer, provided that he refrained from engaging in sexual activity with her. However, at a later point in time, she decided to have sex with him. Following the encounter, she vanished and several months later sent a letter to Kazuhiro detailing her numerous sexual partners.
