Fine

Fine is the pink-haired princess of the Sun Kingdom inside the hollow Mysterious Planet. She is somewhat tomboyish, and is more athletically coordinated than her girly-girl fraternal twin, Rein. Fine loves to eat cake and other sweets, and has a strong rivalry with Milky, the infant princess of the Moon Kingdom, who can eat a whole layer cake in a single bite (don't try this at home!).

Fine and Rein typically stay close to each other, along with their "pet" advisor/mascot, Poomo.
