Future Thing

The year is 2112, and the location is some Europe-esq country, on a planet much similar to Earth called Dosterra. Technology is super advanced; gadgets and gizmos for days. Alien races from other planets exist, and many countries and planets have varying interplanetary immigration laws. 

A young alien named Neeko takes part in an interplanetary foreign exchange program, where they become pals with their "host brother", Danny, his boyfriend Spencer, and so on. Danny and Spencer attend an astronaut academy in hopes of traveling to other planets together. 

On Dosterra, there are two types of kemonomimi: cats and dogs. The characters have the same eye and hair color as whatever breed of cat or dog they are, unless they dye it or wear contacts. Feral cats and dogs do not exist.
