Io Tachibana
Io Tachibana is misfortune incarnate. After being injured in the hosital, seeming to have sustained a broken leg and arm with head trauma as well, she was requested by Hizuki to return to school. On the way she meets Harusame who tries to show her the way to school. For some reason terrible tragedies always befall those near Io. She left her family so as not to hurt them anymore and lives alone in a cardboard box. After seeing this, Harusame invites her back to his house to bathe and she is pulled into the project with him. After warning him that death may befall him if he stays with her, he promises no one else will die, (although mostly to psyche himself out of the pain of Micheal's death) and seems to end up sparking some a crush within Io, who even lets him strip her down to bathe soon after.
