Humans and Predators are no different from one another. They kill, they hunt, they prey. Humans have always been the natural predators, slaughtering and domesticating animals to their will. What happens when the animals retaliate? An unknown strand of genetically modified DNA causes animals to expand and enlarge into terrifying horrible creatures that turn Humans, the apex predator, into the prey. What happens when a man becomes too feared? What happens when the line between human and animal becomes blurred? Arima Gen is an average 18-year-old kid in the heart of Tokyo, where all the action is at. Except, he's everything but average. Being from a village with an extraordinary healing factor, he uses this to his advantage to climb the ranks and become the first ranked Poacher in CAGE, Chimera Activity Guidance and Extermination, or even the world! Yet, in his journey to achieving this idealistic goal, he's met with challenges and ghosts from his past. To truly learn the truth of his own identity, he must understand the world around him first.
