I love this manga.It's called Black Dog.It's about a boy Hei,who's a half-beast or half demon in my case that can use his blood as a weapon(The pic isn't him,that's his rival)Anyways he technically hated because he's a "monster" so he hides his dog ears to keep from people calling him a"Dog". But one day he was trying to be an exorcist and and faced off against a high level Zombie and some girl name Bai comes in and take over because she's a real Exorcist...in training.After the fight she invites Hei to the best Exorcism school....that's all im gonna says.Read it man.
