Standing between civilization and annihilation are the Executioners, the merciless hunters who fight in place of the citizens as humanity's last defense against its greatest predators: the Grenimals, grotesque manifestations of corrupted desire.

Mutuki and Yuri are dispatched on a new mission: infiltrate a clandestine underground auction steeped in danger and secrecy. But what begins as covert reconnaissance soon unravels something far more sinister lurking beneath the surface.

As the pair descend deeper into the auction's labyrinth of secrets, they uncover a conspiracy that threatens to tip the fragile balance of power.

A dark, action-packed tale of blood, betrayal, and the Executioners who walk the line between justice and damnation, where justice is bought, loyalty is tested, and survival demands more than steel and silver.
