Minoru (ミノル) is the leader of Nihonkoku.
Minoru has a balding man with hair in the back and a small beard. He wears a kimono.
Minoru was initially distrustful of outsides, having Sudou Kaname and his friends arrested in relation to two children's deaths because Youta mentioned his name. Due to Nihonkoku's circumstances, he is unfamiliar with modern weaponry such as guns, and therefore underestimated the strength of Kanehira Hideaki's forces until he agreed to let Kaname and his friends help. After the Darwin's Game, he became much more friendlier to Kaname, apologizing for his previous behavior and offering to reward him for his assistance.
