Kuraki Fuzuchi, a reserved swordsman with latent psychic talents, navigates a destiny shaped by ancient shamanic rites and spectral conflicts. His path converges with college student Takeo Nanachi during a sacred mountain festival held once every 49 years, where Kuraki undergoes initiation to cleanse a ancestral blade bound to a departed relative. This ritual irrevocably entwines their fates, awakening shared psychic potential and thrusting them into clashes against malevolent entities from Japanese mythos, including Izumo’s shadowy forces.

A dual narrative intertwines Kuraki’s present trials with echoes of a past life, unraveling historical ties to curses like Susanoo’s and his role as a mediator between realms. When a ritual sacrifice disrupts Nanachi’s own shamanic awakening, Kuraki draws the attention of factions eager to weaponize his powers, forcing him to confront both external threats and the weight of lineage.

His partnership with Nanachi evolves through mutual dependence, their bond deepened by revelations of prior lives and a legacy of recurring destiny. Though stoic in demeanor, Kuraki’s resolve is tested by physical and emotional battles against supernatural adversaries, underscoring his commitment to shielding others from spiritual peril.

Chronicled across manga and OVA adaptations, Kuraki’s story extends into the sequel *Yakumo Tatsu: Arata*, maintaining his roots in ancestral magic and shamanic tradition. As a bridge between eras and worlds, he balances inherited duty with the demands of his psychic gifts, perpetually navigating the collision of human and ethereal forces.
