Races

The way that a society of people, animals, and aliens co-exist is a very complicated balance. There's a division between Terrans and aliens, with the general consensus being that they shouldn't even exist here and have to wear basically space suits in order to survive. A high number of murders have occurred by breaking the suits, and it has the people live in fear.

The same can be said for animals. There's a very clear divide between carnivores and herbivores, with some carnivores giving into their instincts and murdering then eating the herbivores.

Ludis academy is the one glue that holds them together, being a beacon of equality. Most school events aren't just seen as a drama play or a talent show, but a showcase of the races coexisting.
