Koki Yukishiro

Koki is a slender young girl with long hair that obscures most of her face and her round eyes have large pupils. As a student, she wears the Kami High uniform; a dark buttoned up blazer with her school emblem located around the left breast, a collared shirt, a bow, long socks and sandals. Similar to Rin Sawaki, she wears a long dark skirt instead of the standard short skirt. She later does her hair up, revealing that her eyes are naturally almond shaped, as well that she has rather small eyebrows.

Koki is a timid and dispirited girl. As a child, she took pride in her recognition as a talented pianist. After her time in the spotlight was replaced by a life of isolation from her peers, Koki longed to once again be acknowledged, even if the means were improper.
