Michi

Michi is Hideharu's mate and the mother of 5 puppies.

She visits Oscar and his father at their owner's house and they talk in the backyard about how weak Oscar's best friend, Kagura is getting. They don't believe her at first, but she eventually takes them to the arena and shows them Kagura trying to fight a random Tosa and he easily gets defeated. Oscar feels sorry for his friend and he guesses he has caught an illness one day, but Michi tells him that his owner has been taking him out on fights too often. She then leaves the two Kishus behind and returns to her den.
