Comet-san

A twelve-year-old girl serves as the princess of the Harmonica Star country in the Triangle Nebula. She was supposed to meet the prince of the Tambourine Star country at a ball, but he fled to Earth instead. She is sent to Earth to locate him, though she has no description of his appearance. Her only clue is that "he will be known by the twinkling in his eyes." After arriving on Earth, she grows fond of the people she meets and becomes attached to life on the planet.
