Kenpachi (剣八, Sword-Eight) is the title that is only given to the strongest Shinigami. It is an ironclad rule that there can be only one Kenpachi per generation, meaning that the predecessor must die for the killer to succeed the title. To inherit this title, the candidate must kill the current Kenpachi in battle.
