Welcome to Planet R, a place where four crystals representing the elements keep the world in balance. But the crystals of Earth, Fire and Water have been stolen by the evil Deathgyunos. Linaly, a descendant of an ancient protector of the crystals, and Pritz, a headstrong young man, must protect the Crystal of Air to prevent the world from being plunged into Chaos. With the Tycoon military and air pirates after them as well, will they be able to succeed? The story takes place on the same world as Final Fantasy V, named Planet R, set two hundred years in the future, where three of the four crystals have been stolen. The original heroes in Final Fantasy V are now legends of the past, and a new evil, Deathgyunos, has risen on the Black Moon and must be dealt with.
