The spirit realm, Kakuriyo, is torn apart by hatred and grudges between the ruling clans.

There, Suzume finds herself at the center of an intricate political struggle between the yokai clans, each seeking to claim her soul for their own advancement. But the truth behind Suzume's existence is even more horrifying: she is the last surviving member of a clan of assassins, massacred by the Fallen Dragon of the Ningyo.

Hunted by those who want her soul and haunted by the legacy of her ancestors, Suzume must decide how far she is willing to go to survive in her cruel new reality, who she trusts to call a friend and whether she will follow the bloody path her clan left behind.

Will she find a way to break the cycles of hatred and change her world for the better? Can love exist in a world, where it is nothing more than a weakness?
