The opposite to his sister Cath, Mori is a monster. He is violent, and very unpredctable. As a result, a handler must either be very wary or somehow negotiate a truce with him. It is best to keep him away from small animals, and sometimes even large ones. Some say every bone of his is evil but this can not be the case, for he dotes upon Cath. She is probably the only one that gets to see his sweeter side, and that can make him behave. Woe betide anyone that dares to insult or threaten her however. Then all bets are off.
