Seireitsukai no Blade Dance

For starters, both MC's come to a new school, and they are unusual; Kamito is a guy, Raishin is Oriental. Also, there seems to be a tournament, Wiseman's and Blade Dance. Also, the first female character he seems to have contact with is doing this for their family, and her family was once prestigious but then their name tarnished. Male MC's are doing it for a specific person, however one is trying get someone back, and another is trying to seek out revenge. Anybody that watches both can easily understand that they are similar...
