Yes though you spell his name Raizen ,anyway, yes he didn't eat human meat because he fell in love with a human and therefore since he felt disgusting compared to the woman he loved he left her he vowed never to eat humans again till he saw her again

Raisen is the human eating one, because he dies. He don't like to eat humans. Tell me if I'm wrong. I like it though, AWSOME!!!!

w00t for you. ^^
