Shuen no Kokuin

In a town haunted by ancient legends, Rei Kuzunoha searches for his lost sibling, who mysteriously vanished near a forbidden lake. The townspeople whisper of curses, vengeful spirits, and a dreaded Onryō whose name must never be spoken. Refusing to believe his sibling is dead, Rei uncovers a horrifying truth—he was meant to be the original sacrifice.



Marked with the Brand of the Unforgotten, Rei becomes the vessel for a vengeful Onryō fused with the sea's fury, its whispers clawing at his mind, its power threatening to consume him. Now hunted by both the supernatural and the ruthless Shisōkai (Death Burial Society), Rei must unravel the curse’s origins before he loses himself to the entity within—or worse, becomes the next Umi Bōzu.



As the line between victim and monster blurs, Rei faces a terrifying question:

Was his sibling truly taken by the curse... or did something far worse happen that night?
