In Tokugawa-era Japan, masterless ronin Manji wanders as an outcast cursed with eternal life. Having cut down his corrupt lord and one hundred fellow warriors, Manji is afflicted by the mysterious eight-hundred-year-old nun Yaobikuni, who implants sacred bloodworms, known as kessen-chu, into his veins. These parasitic organisms reattach severed limbs, close fatal gashes, and render him biologically unkillable. Crushed by remorse and the weight of perpetual survival, Manji vows to slay one thousand wicked men to atone for his century of killing and secure release from his immortal prison.

His mission collides with Rin Asano, a teenage swordswoman seeking retribution for the annihilation of her family and the ruin of their dojo. Her vengeance targets the Itto-ryu, a renegade coalition of outlaw martial artists headed by the radical ideologue Anotsu Kagehisa, whose mandate is to crush Edo's traditional, rigid sword academies using any weapon necessary. Realizing Rin's vulnerability mirrors his late sister Machi, Manji becomes her sworn guardian. Together they confront not only Anotsu's lethal vanguard, including the devastating prodigy Makie Otono-Tachibana, but also the clandestine machinations of the Shogunate's secret police, the Mugai-ryu, in a merciless cycle of ideological warfare and mutual slaughter.

What to Expect

Blade of the Immortal rejects romanticized samurai mythos in favor of visceral, gritty swordplay and complex moral ambiguity. Rather than relying on superhuman energy blasts or clean dueling etiquette, SAMURA Hiroaki choreographs messy, tactile skirmishes utilizing asymmetrical daggers, chain scythes, throwing knives, and modified broadswords. Pacing shifts deliberate character introspection into sudden, lethal ambushes. Manji's immortality is never treated as a cost-free superpower; limb loss causes acute physical agony, and wounds require precise biological alignment to knit, forcing him to out-think opponents who quickly deduce methods to incapacitate or dissect his unkillable frame.
