Domon Kasshu's
older brother, who assisted their father in the development of the revolutionary Ultimate Gundam while Domon was pursuing his martial arts training. Shortly before the beginning of the 13th Gundam Fight, Kyoji seized the Ultimate Gundam and fled to Earth, where the
mobile fighter
metamorphosed into the evil
Dark Gundam.
Domon is now charged with tracking down his renegade brother, and carries with him a fragment of a ten-year-old photograph to aid in this search.
