Some bones whisper. Others scream. Hers do both.

In a fractured future where climate collapse has silenced the land and outlawed spirit traditions, Rika Kamuy lives in hiding — the last in a forgotten line of indigenous Bone Oracles. She carves fragments of animal bone to survive, secretly embedding them with symbols from her ancestral Ainu bloodline.

But when she uncovers a bone buried beneath a sacred riverbed — one disturbed by the Ministry of Recovery and Preservation — her carvings awaken something ancient, furious, and deeply spiritual. The voices in the bone are not just memory. They are power.

Now hunted by the government and haunted by visions of her burned ancestors, Rika must decide: will she silence the magic inside her... or unleash it and become a weapon for the forgotten dead?
