Chief Sittenrun (シッテンラン Shitteran?) is the current chief of the Tribe of Darkness. Sittenrun is the descendant of Chief Hittenrun. Sittenrun is a peaceful and merciful person. He gave mercy to King Anthony even when he was attempting to conquer Hope. He rarely fights and has his two lakeys, Speekencool and Strikenhurt, to do it for him. After being mutinized by Mockenbully, he admitted his defeat to King Anthony and stopped attacking Hope. He helped Commander Donald refine the Millennium Gummies at Where the Stars Sleep. However, he later joined Destros' Tribe of Darkness and was ordered to kidnap Domesque and Lanette, the daughters of Seppra. He did kidnap them but he felt remorseful. Because he couldn't bear the cruelty of the crime he was committing, he gave the girls to D-Man to give to Destros. When Commander Donald's Advanced Vanguard Team invaded Kalise, Sittenrun fought in the Kalise Castle fascimile of the Tribe of Darkness reservation. Upon seing Sittenrun, Seppra violently attacked him demanding for her daughters. It was then that Sittenrun realized that what he was doing was wrong, so he joined Commander Donald's group. After Destros was defeated and he became King Anthony again, Sittenrun returned to his reservation and stayed there until he was asked by Vice Captain George to help fight Diablo.
