Yukiyumi Koharu

A Madonna-like entity in the school due to her good looks and excelling in anything she does. Has a large fanbase of both boys and girls. She has a serious and refined personality, but for some reason, called Shinji "onii-sama" during their first meeting... Koharu became one of the wife candidates by her own will after the principal showed her a picture of Shinji, and is ready to eliminate anyone who harms or makes fun of him with all she's got.
