Revived from death by the sorcerer Amakusa Shiro after the Shimabara Rebellion massacre, the legendary swordsman Musashi Miyamoto serves in Shiro's undead army. He fights under Shiro's command, wielding his formidable skills to aid the quest for vengeance against the Tokugawa shogunate. Musashi's primary role pits him against the opposing ninja, Yagyu Jubei. Consistent with his historical mastery, he engages in supernatural battles infused with the series' dark fantasy elements of black magic and sorcery. The documented media does not explore Musashi's personal history, motivations, or internal development; he functions solely as an instrument of Shiro's vengeance and lacks significant individual backstory or evolution within the two produced episodes. The series' cancellation prevented further exploration of his role or interactions beyond this initial setup. No additional background, personality traits, or narrative development for this iteration of Musashi Miyamoto are provided in official "Ninja Resurrection" media.
