Comet-san

She has pale skin with blue eyes, and short curled Hot pink Hair with a portion held down by Yellow Star Clip. Her main casual attire consists of an orange hoodie with a green long sleeve shirt worn underneath, a purple jean skirt, yellow socks and red and white sneakers.

Her transformed outfit (and normal attire in the Harmonica Star World) is a pink dress with a hot pink pleated skirt under the frill-shaped split, and a see-through puffed-sleeved shirt worn over it. She also wears white frilly gloves, white boots, star earrings and a pink crown with a star resting on top of her head.

Her upgraded Love Power Form is more detailed then the last, consisting of more frills, ribbons, and a heart motif instead of a star motif.

After escaping a ball, Comet runs into a mysterious person who drops a crystal. Unbeknownst to her, he is the Prince who has fled from the Tambourine Star Country and escaped to Earth. To her excitement, she is then assigned to go down to Earth and track him down, while also being accompanied by Rababou. To do this, she is must use the Tinkle Star and detect a twinkle in one's eyes.

When she arrives on Earth, she is mostly clueless about certain aspects of it, leaving her with no place to stay when night falls. However, she is taken in by the Fujiyoshi's and their twins Tsuyoshi and Nene, giving her a place to stay throughout the remainder of her time on Earth.

Despite her responsibilties, she doesn't care much about her duty of finding the Prince, as she wishes to just enjoy Earth very much like her own mother did.
