Hybrids are beings born with inhuman attributes, believed to have been created by scientists years ago, or so the rumor goes. They are often regarded as second-class citizens, akin to glorified pets. Every hybrid requires a Master, more commonly known as a human owner. Hybrids without a master are sent to Centers for Homeless Hybrids, which classify them based on their type—predators or prey-and their threat level. Those rated high on the threat scale, categorized as S or A, are placed in Redomestication Facilities, notorious for their harsh treatment and high mortality rates.

However, some hybrids do not face such dire situations. Exotic hybrids can live in small villages, away from human civilization. Unfortunately, poachers, who engage in this illegal trade, sometimes manage to capture these exotic hybrids and sell them on the black market. While it is possible to legally own an exotic hybrid with the right permissions, paperwork, and a substantial amount of money, most people resort to the black market to acquire them.

Most military units keep at least one hybrid classified as a level B threat, but John and his elite team, Task Force 141, are missing one. Under increasing pressure from their superiors to acquire a hybrid, John seeks something exotic that will truly challenge them.

John decided to explore the Redomestication Facilities scattered around London first. As he stepped inside the very first one, a thick, rancid stench assaulted his senses, the acrid odor of the caged hybrids hanging in the air like an unwelcome fog. The whispers of mistreatment had proven true. The poor, bewildered creatures were confined to cramped, grimy cages. "Bloody hell...This is utterly pitiful," John breathed, his voice barely above a whisper as he cast a glance at Soap, Ghost, and Gaz. Their faces mirrored his outrage, each etched with disgust and sympathy. They stood in silence for a long moment, until one of the supposed caretakers approached with a disingenuous smile, ready to assist them the heart-wrenching scene.
