The Century Kings (世紀王 Seiki Ō) are the two candidates for the leadership of Gorgom. Every 50,000 years, the existing Creation King dies. When this time draws near, two Century Kings are chosen, eventually to fight each other, the winner claiming both King Stones (and the loser's life, if not in the battle then in the extraction of the King Stone.) and becoming a new Creation King, to rule Gorgom for the next 50,000 years. It is for this that Kotaro Minami and Nobuhiko Akizuki were chosen.
