/t/ - Theories

Sabitsuki was a radical environmentalist who used arson as a weapon. She was well-equipped for such an act (the gas mask) but somehow ended up getting hurt. She was clinically dead for a time, and suffered some kind of brain damage. She also probably suffers from a terminal illness (AIDS?), which is why she is willing to put herself in such danger to begin with.

Madotsuki is Asperger's and suffers from feelings of social isolation. There doesn't seem to be much more to it than that. I admit this is kind of a lazy theory.

Urotsuki is a totally normal girl who goes to an average high school and gets good grades. She is an artistic genius, and her dreams are full of the kind of whimsical things that are the subject of her paintings. However, they are also tinged with pain and fear because of the time she was [spoiler]sexually assaulted[/spoiler] near her home. Also bulemic.
