北斗神拳
is the "Hokuto Ryūken" master who trained the three "Rashō" and Shachi. In the past, he went through a demonic possession as a result of his misuse of his style, killing his wife and child, but was rescued by Ryuken. He then trained Kaioh and Hyoh, sealing Hyoh's memories of Kenshiro and his knowledge of the original Hokuto style. The main reason for the training Kaioh, Hyoh, and Han the art because Shura needed defenders of the land and each had qualities that prevented them from learning Hokuto Shinken; Kaioh was filled with hatred, while Hyoh was emotionally attached to his brother; despite knowing the risks involved, he taught Hokuto Ryuken in order to buy time so a Hokuto Shinken successor will return to Shura (expecting it would be Raoh). In the present, he forms part of Leia's resistance, after Hokuto Ryuken has corrupted his students, and attempts to undo the seal to prevent the two brothers of the Hokuto Soke from destroying each other, which would result in the absolute destruction of the Hokuto Soke bloodline. However, Hyoh's seal was compromised by Kaioh, and any attempt to restore Hyoh's memory was lost. Realizing what Kaioh has done, Hyoh gives the mortal blow; dying, Jukei would regret his past deeds as his mistakes may doom all of Shura.
