Humanity trembles before the Grenimals, grotesque creatures born from corrupted desire. Among them roam the Lycanthropes, savage beasts driven by their lust for chaos and pleasure, and the Vampires, who see humans as nothing more than cattle to be bled dry.

As the world teeters on the brink of madness, those who hunt what should not exist, the Executioners, rise to stand against the encroaching darkness.

Among their ranks are Mutuki, a stoic, battle-hardened warrior, and his sharp-witted partner Yuri, as they plunge into one supernatural mystery after another, each case more twisted than the last, each unveiling horrors festering in the shadows of their crumbling world.

A dark action fantasy of mystery, survival, and vengeance begins, where the line between hunter and hunted begin to blur.
