Hiroshi Mitarai, also nicknamed "Dai-chan" or "Poops" (pun of the Japanese character bathroom), is a very eccentric person always trying to outdo Ten-chan in anything. He also tries to win over the heart of Misha, much to her oblivion. He is very knowledgeable in traditional Japanese arts, and because of this he is able to guess that Shia is a demon.
