Beast Complex is a Japanese manga series written and illustrated by Paru Itagaki. It is a compilation of short stories set in the same world as the series Beastars; its original run served as a predecessor for Beastars, and some of Beast Complex’s stories expand on characters from Beastars. The stories take place in a modern world occupied by anthropomorphized animals of various species. The animals are divided into carnivores and herbivores, and eating meat is illegal since it can only be sourced from anthropomorphic animals. Carnivores and herbivores often come into conflict due to the former's craving for meat.
