Kagura Chizuru

Yoshiaki's younger sister.
Although her face still has a childish appearance, her body is already hardly that of an infant, and her breasts and buttocks are unusually large. She is a pampered child and a shy one. By nature, she is timid, but she has a keen instinct. Accustomed to being pampered, she has become somewhat selfish. She is very attached to Yoshiaki and does not try to hide her feelings for him.

She sees Mika being attacked by the protagonist, but is unable to tell anyone about it.
