Personality: Blunt and to the point. Doesn't converse as much as she should as the main character. Is that awkward? There's a reason why though. She sleeps alot for some random reason. Often falls asleep in conversations or looks blank and shows no sign of emotion, though she's a team player. Rarely smiles or laughs due to personal issues. She prefers being alone and not taking charge, but she'll do anything for her best friend who has no name yet. Why? Because he's dead. She didn't know that until she was dropped into the maze. Another thing is, she doesn't "like" her best friend in that way. He has a girlfriend, and Kasumi has a boyfriend (who she hates to death).
BIO: The problem Kasumi's always had is her disease called Angina pectoris. Every now again again, she has to go to hospital to check up on it or she experiences one of the symptoms of it. She's a very intelligent girl, one of the best in her class, despite the lack of participation. One of the guys in her class ended up black-mailing her, so she had to go out with him and still does. She hates it though. She gets beaten on a weekly basis by him, which is why she's one of the only girls in the school who's allowed to wear a collar and doesn't have to wear the girls school uniform. Her parents are divorced, and she lives with her mum. Her dad doesn't live too far away, so they keep in contact alot. Her best friend was involved in an accident and was lucky to have survived, the doctors said, since he was the only survivor. Little did anyone know, he had died. But at the wrong time. Which is why the priestess allowed him a chance to earn his life back.
