七瀬 千春

Brotherly term of endearment: "Onii" The daughter of Souichirou and Koharu. She always smiles when they’re together. A lover of anime, manga, and video games, she’s abnormally close with her brother and plays with him constantly. Her high level of energy rubs off on the rest of the Nanase family. Chiharu is inclined toward exercise, and is a member of the cheerleading squad. She eats a lot, plays a lot, and sleeps a lot, but hates to study. Unlike most of the other sisters, she doesn’t even try to hide her love for her brother. Whenever she sees the chance, she charges right at him with a powerful tackle. She’s happy to talk about sex, and even tells dirty jokes like they’re nothing. Chiharu is also not shy about trying to seduce her brother, no matter the time or place.
