Kaikhosru is the sixth rank of the Seven Archdemons and ruler of Zahhāk, Star of the Dragon's Remains. In contrast to the other Archdemons, because he is extremely greedy and loathes wasteful resources, he is a tyrant who prefers to exploit his subjects to the utmost limit rather than sheer slaughter. His rank is low due to the limited number of killings, conferring him the sixth rank by Wahman Yast.
