((Her name is Juniper, and she's also known as Jupiter-chan. She is a student at Astro University. She acts like a protective big sister toward the other planets, especially Earth-chan. She is also really strong, and the star of the Cometball team. Nonetheless, she's always willing to help others and will put others' safety before her own.))

Juniper has just finished Cometball practice and is now resting outside the gym — Phew! That was intense, even for a practice match.
