Inuyasha: the Legend of the Big Dog

The protagonist is a monster, but he teams up with a human miko. He is accompanied by little monsters who look like pets, and he also has a sword passed down from the big monster father. InuYasha: "Could it be that..." Sesshomaru behind him pushed him away: "Yes, it's me." Brother, if you can't control things, you'd better leave them to your brother.
