At this high school, instead of jocks and nerds, the students are divided into predators and prey.
At a high school where the students are literally divided into predators and prey, friendships maintain the fragile peace. Who among them will become a Beastar—a hero destined to lead in a society naturally rife with mistrust?
Gray wolf Legoshi begins training with giant panda Gohin in order to better protect his friend, but he faces an ethical paradox when he is told he must eat meat to grow more powerful. Meanwhile, herbivorous red deer Louis is choking down the flesh of beasts to maintain his status as the leader of a carnivorous lion gang. Yet when he runs into Legoshi carrying a bag of meat, Louis feels betrayed. Legoshi continues to train, becoming more powerful in some ways yet weaker in others—and then his grades begin to drop. Even worse, dwarf rabbit Haru is mad at him!
