Yamada Asaemon, Shugen

山田浅ェ門殊現

Yamada Asaemon Shugen serves as the second-ranked Asaemon of the Yamada clan and is a former Assistant Instructor. Recognized as the clan's most powerful swordsman, he assumes the role of de facto leader for the supplementary landing force sent to Kotaku Island after the Shogun loses patience with the vanguard's slow progress in securing the Elixir of Life.
He distinguishes himself from other Asaemon by donning a bold black uniform rather than the customary white, a visual representation of his uncompromising stance against evil. He handles the named blade "Fuributsu Kaneaki" with masterful precision.
His character is marked by unwavering loyalty to the Yamada clan, which he considers his true family, and an absolute, nearly fanatical commitment to justice. After losing his parents to a criminal during his childhood, Shugen cultivated a deep-seated hatred for all lawbreakers.
