Humans

Humans are the dominant species on Earth. For this reason, they are watched over by the Fairies who reside above in Fairy World (which, depending on the episode, is either in the clouds or an entirely different planet/universe all together). The vast majority of humans do not know or believe in the existence of fairies, but those that do are considered crazy. The only humans that truly know about fairies are godchildren who have been given a fairy godparent because they are miserable, and this child must keep their fairies secret from everyone they know or risk losing them forever.
