Taishaku-Ten is the rebel who claimed the Ten-Tei(God-Emperor)'s seat when his forces overwhelmed and defeated the former Ten-Tei's and Ashura-Oh's forces. He is extremely powerful and he also has four Shitennohs to guard him. Shitennohs are higher in rank than the Bushinshohs and each Bushinshoh is assigned under one Shitennoh to guard the four directions of the Heavenly Kingdom. Outside the boundary of the Heavenly Kingdom is the I-kai, the Other World, where the demons reign. These demons are ever trying to invade the Kingdom. Taishaku-ten's "most treasured thing" and his sole reason for living was his promise made to Ashura-Ou -- to never allow Ashura from turning into the Real Ashura, or, if he failed, to kill Ashura. In return, Ashura gave Taishaku-ten his "most treasured thing" -- himself.
