Toshiyuki

He is a vicious dog that lives in town (though fears Makiko), and Miki's strongest non-human opponent. He is very strong as shown when he was able to act as a mount. Miki seems to understand its growls and barks, and thus she says it claims to bite people for the sake of world peace. Later on he becomes friends with Kankuro. He also appears in the every episode's ending video.
