Comet-san

Twelve-year-old Princess Comet hails from the Harmonica Star country, located in the Triangle Nebula. She was scheduled to meet the prince of the Tambourine Star country at a ball, but he fled to Earth before the encounter could take place. As a result, Comet is sent to Earth to search for him—despite having no idea what he looks like. Her only hint as to his identity is that "he will be known by the twinkling in his eyes." Upon arriving on Earth, Comet finds herself falling in love with both the people she meets and the planet itself, and she quickly grows attached to life there.
