Yuutenji Ayako♀

A year before, she was getting along well with her father, but after realizing her own carnal desires, she started distancing herself from him, knowing its a feeling which cannot be allowed. Because of her cold attitude towards him, Shirou thinks that he's hated by her, but actually, Ayako continues to look at him as a man. However, after hearing that her father got confessed to by his subordinate, she couldn't tolerate it, and so she tied her father while he's sleeping, and then raped him. After that, to make him her own, she seduced him through different ways.
