On the planet Lunar, a thousand years had passed since a great war with the evil sorcerer Ghaleon. One of the heroes of this war was Nall, a small flying cat who
turned out to be a dragon. Now a new group of
protectors have to fight the resurrected Ghaleon. One
is the young Hiro and his pet Ruby. Ruby appears to be
a flying cat like Nall, but she can also take on the
form of a mighty dragon. Plus, she can assume a human
guise. Ruby has a fondness for her master Hiro and
gets jealous when he starts getting to close with his
friend Lucia. Ruby and the others eventually help free
Lunar a second time to the planet safe for future
generations.
