Nanase Aya

Brotherly term of endearment: "Nii-san"

A cheerful, always smiling, gentle little sister.

She enjoys cooking, doing the laundry, cleaning, and other household chores. With both parents away, she looks after everyone.

She’s always loved her older brother as another guy, and thinking about how she’d want to be lovers with him, it appears that she’s interested in sex.

”But I’m his blood-related little sister!” as she takes a step back while worrying about that every day.
