Kaori Tachibana

A high school freshman from the Reien Girl's Academy, who died in the fire incident. She was an acquaintance of Ouji Misaya since they were in the elementary level classes. She was forced to go outside by Hayama Hideo and got impregnated. Being a pure Christian, she struggled by herself for several months, and finally killed herself hoping that will be a way to save the souls of her guilty classmates and herself. If the person she talked to wasn't Kurogiri Satsuki, it wouldn't have happened...
