Beastars is kind of like the movie Zootopia, if you've seen that. But darker. In the Beastars world, there are no humans, but there are very human-like animals instead. There is a lot of tension between herbivores and carnivores, because carnivores have to fight or safely satisfy their urges. In school, young carnivores are taught to suppress their instincts and to eat eggs, insects, and plant protein  (like tofu) rather than other people. 

But adult carnivores tend to turn to the black market. Some of this meat is provided through hospitals and morgues, but some poor souls were captured to be sold as meat, or bred for that purpose, usually run by carnivore gangs. And sometimes, they just can't suppress their instincts. 

Couples usually consist of the same species (because cross breeding isnt possible), but interspecies coupling is common especially while young. Herbivores normally befriend herbivores, and carnivores beffiend carnivores. In Beastars, our main protagonists are an unlikely high school couple: a shy grey wolf bou and a promiscuous  white dwarf rabbit.

The manga is really great, and I would love to participate in a roleplay based off of it. But I would like to see more participants before I commit...
