Buzen Gou is the 77th sword obtained by the Saniwa at Hanamaru Citadel in the anime continuity. As one of the anthropomorphized sword warriors known as Touken Danshi, he appears in the "Toku Touken Ranbu: Hanamaru ~Setsugetsuka~" film trilogy. Within the "Setsugetsuka" narrative, Buzen Gou forms a friendship with Nansen Ichimonji, distinguished by the comfortable nature of his lap as a connection point. He also integrates into the broader social circle of Gou swords, where Tsurumaru Kuninaga displays camaraderie toward him and others in the group, despite no established historical or thematic link within the original source material.
