Peruru is one of the Dream Fairies that protects the dreams of children. His older brother, Pupulan, was lost under the seemingly sweet ideals of Badiyanu along with the other two fairies, Bananu and Oranja. He then met a sweet, and interesting kid, named Rini. They spoke of sweets and mothers that loved their children. She gave him her special, hand-made cookies before they parted. Later, Pupulan was stealing more children away with his song of a land of sweets. Like the pied-piper he led them to his ship. When Rini was taken as well he joined with the Sailor Scouts in hopes to save her and stop his brother.
