Yasaka (ヤサカ) is a mysterious green-eyed warrior and successor of the Seito Gekken. A descendant of the Yuezhi who carries their nearly 2,000-year grudge against the Hokuto and believes God has chosen him to destroy it. This extends indiscriminately to other fists that have descended from the Hokuto, such as Liu Zongwu's Hokuto Ryukaken and Liu Feiyan's Kyoku Jujiseiken. He also prays to the moon every night.
He works as a bodyguard for Dù Tiān-Fēng and claims his name is ancient Hebrew for "to see God". He robbed a Kuomintang train and gave away all its food to peasants. Though captured he escaped execution after Tiān-Fēng paid for his freedom.
Later it is revealed that he is a descendant of Shuken and Yama's child, thus making him a member of the Hokuto Sōke bloodline. He eventually redeems himself and joins Kenshiro Kasumi and his friends.
Since the anime was canceled before his character was introduced into the story, Yasaka only makes a cameo appeareance in the second closing credits.
