Kyuju Amagiri, an enhanced warrior of the Tosa Domain Furies forged by the Water of Life, operates among factions opposing the Shinsengumi. During a pivotal clash, he exposes the lethal toll of Fury powers—each supernatural surge hastens physical decay and mortality—reshaping strategies for allies and foes alike. Partnered with fellow Fury Kyo Shiranui, he coordinates assaults that fracture enemy formations, compelling retreats or tactical overhauls. On a nocturnal patrol, the pair corner a rogue Tosa Fury whose abrupt collapse into ash underscores the dire cost of unchecked power. Amagiri’s maneuvers intertwine with wider conflicts over Chizuru Yukimura’s pursuit and the orchestration of Fury forces. His battlefield interventions amplify the Shinsengumi’s crises, mirroring the era’s tangled loyalties, betrayals, and ethical quandaries surrounding the Water of Life’s corrupting allure.
