Black Hayate

Black Hayate is a little puppy that was found by Kain Fuery on the street in a rainy day. But, Fuery can't take care of the puppy because he lives in a dormitory. He asked to all the people possible that might take care of it; the Elric brothers, Jean Havoc, and so go. But he didn't found someone that could take care of Black Hayate, so, Riza Hawkeye adopted it.
