After dying valiantly against the Upper Moon Three demon, Flame Hashira Kyōjurō Rengoku awakens not in the afterlife, but in the strange, technologically advanced world of Remnant. His Breathing Techniques, now fueled by his own Aura, prove devastatingly effective against the monstrous Grimm, drawing the attention of Beacon Academy's headmaster, Ozpin. Offered a position as a combat mentor, Rengoku accepts, seeing it as a new path to protect humanity. He forms a complex bond with Team RWBY, particularly their leader Ruby Rose, whose earnest idealism both challenges and resonates with his own unwavering spirit. However, his resurrection is not a miracle; it's an anomaly caused by the activation of a Relic, an event that has also drawn the attention of Salem's inner circle. As Rengoku hunts for answers about his return, he must master Remnant's power system while protecting his new students from threats that dwarf the demons he once knew. The ticking clock is Salem's plan to claim the Relic that anchors him to this world, a move that would sever his existence and unleash a devastating new wave of Grimm upon Vale. Rengoku must unite his samurai code with the tactics of modern huntsmen to confront this meta-threat, forging a new flame of hope in a world desperate for a hero.
