In a prehistoric reimagining of Yokohama, two dominant raptor packs control the landscape: the Detective Agency Pack, led by the calm and unshakable apex Fukuzawa, and the Port Mafia Pack, ruled by the calculating predator Mori. These are not simple animals. Each raptor carries distinct physical markings, scars, and behaviors shaped by territory wars, pack loyalty, and survival strategy. The ecosystem is balanced through tension rather than peace—every border is a negotiation written in claw marks. The Agency pack operates with precision and coordination, valuing survival through structure and prediction. The Port Mafia pack thrives on dominance, aggression, and territorial control. Neither side fully dominates the other. Instead, they exist in a constant state of restrained conflict—like two storms circling the same sky, waiting for the moment one finally breaks the atmosphere.
