Ikezawa Hanako

At a young age, Hanako had a traumatic experience that left her life in shambles. Her parents died when/ her home burned down in an accident, which also disfigured Hanako herself permanently. She is reclusive to the extreme, shunning from all other people to the point of actually panicking from any social contact. Her only trusted friend is Lilly, who has taken Hanako under her wing ever since the two were introduced to each other.
