Clair Aoki

A female freshman from Shuichi's highschool that in the beginning of the series attempts to commit suicide by immolation due to the death of her parents to the hands of a "monster." She is saved from this situation by Shuichi. Whilst being saved, she discovers Shuichi's other form and with this information she later convinces him into doing what she wants him to do. She is a rather smart girl that takes advantage of any opportunity to gain the upper hand in any given situation be it by using her female attributes (mostly against Shuichi) or by using the enemies' secrets and goals against them
