Voiced by	Aoi Miu
Description In contrast to her hot-blooded sister, is a serious and cool girl that loves to study. It may seems she looks at things with composure, but in reality she often reacts absently. Stubborn, with never pulling back once she decided to do something on the one side of her personality, and bursting into tears in confusion, once something exceeds her maximum level of understanding on the other side. She believes in the lies of the protagonist that he is her mother's lover and, for breaking apart this relationship, sacrifices her own pure body...

Description Breasts that sway only by walking, slender but well-built limbs. No doubt that this impudent and radical behaviour, like hitting protagonist, Kenji, right into the face the second she first saw him, will urge every man to sexually train her. While being such a violent person on the one side, she also has the other side of her personality, being capable of frankly accepting a partner... Will Kenji's view of life dramatically change being caught in such a strong personality?
