Yamashina Sayaka

Daughter of Natsue. She is a schoolgirl with big breasts in spite of her young face, she is an honor student who thinks she has to be strong because her mother is quiet.

In contrast to Natsue, with whom she immediately opens up, she is wary of the protagonist at first. She sometimes calls him a “pervert” due to an ill-advised misunderstanding.

She has never been with a man. She has no sexual experience, has not even had her first kiss yet, and is not immune to men.
