and Kujo were ordinary boys from a peaceful village—until the day demons came and tore their world apart. Left with nothing but the ruins of their home and the haunting memories of their fallen families, the two survivors are taken in by a mysterious man who begins training them in an ancient, dangerous power known as Kutsu—a force drawn directly from emotion.

But Kutsu is no ordinary energy. It listens. It reacts. And it corrupts.

As the boys are pushed to confront their inner darkness, they begin to unlock terrifying abilities—and painful memories. A single thought can poison the air. A flash of rage can destroy a village. When Ren and Kujo return to the place they once called home, their grief unleashes a force beyond their control… transforming their village into a cursed shrine of shadows.

Now, burdened with guilt and unstable powers, the boys must walk a path between light and darkness—before their pain consumes not just themselves, but the world around them.
