Mai-Hime

Summary
Mai and her brother Takumi don't have any parents and go to their new school, but on the boat trip to there some weird things happen and Mai finds out that she has some special power, just like the other two girls she meets on the boat. At her new school it turns out that she was summoned to that school because of her power. Mai doesn't like this at all because she has enough problems as a normal high school girl and on top of that her brother has a weak heart so that she has to work hard to earn enough money for their living. But of course :P she can't ignore her power when tah monsters are coming. She wants to protect her school, brother and her new friends, but she doesn't want to fight. She is not the only one with powers on her school, but is this a good or a bad thing?
