Kakyuu

This is the Starlights' princess, Princess Fireball. She first appeared when Sailor Moon allowed her star seed to be extracted—she'd been hiding from Galaxia all along, while on Earth to look for the "Light of Hope" (which, by the way, is Chibi-Chibi). She's no match for Galaxia, however, and can't hold out long in battle. I think she used to be a senshi at one point, but details are vague there. This is all we know about Princess Fireball. Actually, Renee, I know something about Her. She was a senshi at one time, and gave her life protecting Sailor Moon. She lived for four days doing that.
