Tiny is the youngest of Akakiba's children. He's a puppy, but has the mind of a grown-up dog because he was born a genius. He doesn't mind the fact his name will be Tiny forever due to his parents' uncreative ideas.

His siblings never make fun of him because they think he was born with a wonderful gift that caused him to be so smart. Sayoko, the mate of his brother, Takeshi comes to his aid when he's attacked by a bear leaving Takeshi afraid she'll fall in love with Tiny, but she doesn't and takes the mature puppy back to his siblings who are gone. They have went to join the Ohu army who just took them before Sayoko and Tiny came for them. Sayoko suddenly comes out as a pedophile and falls for Tiny and they start living together.
