well I'm not as good as my sister at writing but I would love to help;

Katai is 17 years old he has brown hair and red eyes,his background is a mystery but we do know that he is a very good swords man and he has a demon deep down inside him that is released whenever he gets very very angrey or is at risk of dieing.Katai can only do a few simple magic spells but hopes to improve himself.

thats all i got sorry.
