Ancient Japanese mythology bleeds into the modern world when agents of the Kikuchi Clan detect unmistakable signs of catastrophe. Susanooh, the God of Darkness, stirs in the underworld after centuries of slumber, and his awakening threatens to unravel the fabric between realms. Armed with forbidden knowledge and relics passed down through generations, the clan's investigators race against time to prevent total annihilation. Their mission centers on finding a single boy, chosen by fate to become a vessel for powers that should never be wielded by mortal hands. Caught between protecting him and containing the forces he represents, these guardians must confront not just the spreading darkness, but their own connection to a primordial past that refuses to stay buried. Spirits of the underworld manifest with violent intent, each encounter pulling the boy deeper into a destiny he never asked for. What unfolds is a tense supernatural thriller rooted in Japanese folklore, where ancient rivalries resurface and the line between savior and apocalypse grows increasingly thin. Expect psychological horror grounded in real mythology rather than invented lore.
