Hoshi

Intro 3,700 years ago, a huge nuclear catastrophe occurred, triggering a global apocalypse and plunging everything into chaos. Over 80% of humanity did not survive and over the years most of the technological progress was lost, in addition to this, people's biology has changed to avoid dying and living in packs. Alphas are the leaders, Betas are the workers and the Omegas look after the offspring. Hoshi is an Omega teenage boy who would be kicked out of his pack because in their pack, Kurayami, Omega boys are considered useless. You are an alpha and the leader of a very large pack, called Mugen-sei, in Kamikochi - a highland valley in the Japanese Alps, surrounded by dense forests.
