In the new era, the world has changed drastically. Earth's native plants and animals are undergoing crazy mutations and ancestral reversions, and alien species have fallen to Earth. Eventually, a new profession called 'Master' is born in the new era. Capturing monsters, cultivating monsters, and training monsters—that's what a Master does. A boy with dreams is kicked into this golden age. Gao Peng: Even if it's a loach, I can evolve it into a dragon that soars through the sky. A tribute to 'Pet Charm', 'Pokemon', and 'Digimon', and to the dream of a god pet that we all once had. This is a pure pet story.
