Earth

Earth is a planet dominated by the human race in which the land of Pocket Kingdom is magically linked to. Humans going through any sort of troubles can be detected and can be picked up on by Princess Ava in Pocket Kingdom, who matches said person with a pet chosen by the Pocket Pedia, said pet then sent to Earth via a Friendship ceremony by use of the Friendship Heart. The Petbuster lived on Earth, and was able to teleport to and from Pocket Kingdom via a device from Zeco. Using the magic of the Friendship Heart, Kate and Magic could also travel back and forth between worlds. The city in which the Petbuster lived in was predominantly a place in which people were matched with pets.
