Bull is a Butcher, an android programmed to kill. Every life he takes is a promise to himself to find a way out, a promise he keeps breaking. His kind aren't designed to feel pain... but Bull does.

Mix is a Doll, an expensive pleasure droid meant to serve humanity's needs. His best client is a powerful man who dreams of stealing Mix away. But Mix has other plans.

Opportunities are scarce in the grimy, neon city torn apart by gang wars. Greedy crime lords control the food supply and every aspect of human or droid life.

Both droids are owned by the same ruthless kingpin who intends to use them to consolidate her power by taking down a major rival.

Bull and Mix have never met. But they will.

This fateful meeting could unlock emotions neither knew they were capable of and shift the power dynamics of the entire city.
