Few villagers are happy when Detective Tohru Takuda returns to his hometown to investigate a string of suspicious disappearances. Even the local police chief tries to shut him out from the case. For behind the conspiracy lurks a monstrous living relic of Japan's pagan history: the Kappa. Protected long ago by a horrible pact with local farmers—and now by coldly calculating corporate interests—the Kappa drains the valley's lifeblood, one villager at a time.
As the body count rises, Takuda must try to end the Drowning God's centuries-long reign of terror, and failure means death…or worse.
