Zenouji Ruri

She is pure, innocent, kind, honest, and quiet, a so-called "young lady in a cage". She is reserved and always takes a step back, and does not often come forward on her own, but when the time comes, she has the audacity and core strength to take aggressive action.

Although she is prepared to become a sex slave for the sake of her family, she is so naive that she is strongly embarrassed by the protagonist, blushes when he approaches her, and is unable to speak properly. Although she is unaware of it, she has a predisposition to lewdness, and when she feels pleasure, she immediately becomes promiscuous.
