Mitsuo was a very large man. In the beginning he travelled along with Himiko, Masashi Miyamoto and Isamu Kondō. Not much is known about his past, only that he had sex with a girl he liked once, and that afterwards everybody at his school hated him (implying that it may have been rape, a fact he seems to be unaware of). This could lead to him being sent to the island.
