Poor Ally has a mental illness - a Multiple Personality Disdorder, or MPD for short. It complicates her life to a maximum as she is somewhat aware of what she's doing when she's not . . . herself. When she's her true self, the one she was born as, her nickname is Ally. However, when she's not herself she goes by Araignée. Araignée is able to get into Ally's memories, but the vise versa does not happen.
Ally is an innocent teen, a rare type in today's day society. Araignée is quite the opposite. She's not some immature pervet teen, though. She's just brutal, sadistic.
