In this world, there are three classes- Alpha, Beta and Omega. They are distinguished by how powerful they are, and the shape of their pupils. Alphas are the most dominant and powerful type, while Betas are the casual, ordinary working class. Omegas are usually submissive, and the least powerful. Everyone also has wolf-like features such as wolf ears, retractable claws, and a tail, and different shaped pupils depending on their class.
