Kio Hakoko is a Vandal battle ritual that is used to determine who the leader of the Vandals will be. It usually takes place when one Vandal challenges the current leader or in the event of the current leader's death. Tradition demands that the victor kill his opponent, but this tradition has been broken twice -- once by Grimian and once by Kalus.
