Kyoichi Motobuchi (元渕恭一 Motobuchi Kyōichi) was the son of a man who was the director of environmental affairs in the prefectural government. Kyoichi, possibly in order to live up to his father, would study hard that he barely had time for friends or sleep. He was also the male class representative. Kyoichi had the second best grades in his class and he was quite selfish and thought himself more important than the rest of his class because of who his father is.
