Yonetarou Migimori (右森米太郎 Migimori Yonetarou) is the first prime minister seen in the series, but right after his introduction it is revealed that X had killed him and assumed his form, just to see the cells of a person of high authority. Unsurprisingly, X was left disappointed as the cells showed no difference from normal cells.
While using Migimori's form, X had the minister's subordinates investigate Neuro's background, but when they came up with no results, he revealed himself and killed the men.
