In 1071 he killed the Master Assassin Kurosawa no Takeshi attempting to find the Source of Eden. In 1090, he finally located the Source of Eden and briefly wielded its power until he was killed by the Assassin Kurosawa no Rōnin, the son of Kurosawa no Takeshi.
In the Modern era, he was an inspirational figure to the Templar Order and his daishō was displayed at the Abstergo Industries facility in Ontario, Canada.
