Often referred to as "Comet-san", Comet is a bright girl around the age of 12 who is very kind towards everyone. Though she is the princess of the Harmonica Star World, Comet seems to disregard her high rank and would rather play with little stars than fulfilling everyone's expectations by marrying the prince of the Tambourine Star World. After the prince disappeared, Comet was sent to Earth to find him, but in truth, Comet just wants to go to Earth to have adventures just like her mother did when she was younger. Comet cares deeply for everyone; her gentle nature makes her easy to get along with, and people can't help but like her. She also enjoys helping others whenever they need help and will never stop lending a hand towards her friends. Even as Comet is very mature for her age, she has a lot of lessons to learn in life. Comet also is inexperienced with feelings she's never felt before, which is why it takes her a long time to realize that she is in love with Keisuke. In the end Comet returns the memory stone, which the prince dropped at the day he ran away to Earth, she ends up going back to Earth.
