Ninpou Isekai Tensei: Fuuma Kotarou wa Isekai de Ningen wo Torimodosu

Set in the fifteenth year of the Tenmon era, Fuuma Kotarou—the fifth generation of a formidable warrior lineage—navigates a brutal landscape defined by relentless warfare and terrifying supernatural threats. Driven by an uncompromising will to survive, he battles through countless enemies, repeatedly cheating death through sheer determination. However, his desperate struggle ultimately ends in capture and execution, seemingly closing the final chapter of his violent life. Yet death does not claim him permanently. In the moments following his execution, an enigmatic entity known only as "The Seer of Worlds" intervenes, initiating a miraculous cycle of reincarnation. Fuuma Kotarou is transported into an entirely unfamiliar realm, granted a second existence far removed from the bloodshed of his past. This new world offers more than mere survival; it presents a profound opportunity for redemption. Reborn with the memories of his harsh former life, Fuuma Kotarou must now embark on a deeply personal journey. No longer bound solely by the instinct to kill or be killed, he seeks to reclaim the humanity he sacrificed during his years as a ruthless warrior, forging a new destiny in a strange and uncharted land.
