Two pairs of young lovers become embroiled in a war between two rival kingdoms, the primitive but resplendent Isa and the militaristic but undisciplined Paro. Izu and his young wife, Marin, are simple farmers who live in the unassuming village of Saki, which lies directly between Isa and Paro. While Saki does not have the beauty of Isa nor the war machines of Paro, they do possess a magnificent tree known as "Windaria," to which the villagers give their prayers in return for "good memories." When the war erupts, Izu decides to join Paro's army, enthralled by the fantastic motorbike "given" to him as a bribe. Before he departs, they each take a vow: He will definitely return to her, and until he does, she will wait for him. The other two lovers are Jill, the prince of Paro, and Ahanas, Princess of Isa. They initially want nothing to do with the rapidly escalating conflict, but after Jill's father, Paro's king, dies by his son's hand in an altercation over the war, Jill has little choice but to realize his father's final wish: the taking of Isa. The only problem is that he had promised his beloved, Ahanas, that he would not become involved. Windaria is a war parable set in a fantasy land of unicorns and ghost ships.

A quiet, polite, lonely immortal esper about which little is known, he is called "Locke the Superman", but often denies being so. It is not known where or when he was born, and if asked, Locke will say he does not remember. It is entirely possible this is true. However, when asked by Cornelia Prim in "Millennium of the Witch" which star he was from, Locke replied "Toa." He has appeared at various times throughout the history of the galaxy, either as a direct influence, an indirect influence, or a simple observer. Using his esper abilities, Locke can learn and do most things more quickly than a normal human. His power also allows him to remain eternally young, or even turn himself into a child again to be adopted by kind-hearted families. It is speculated he remains youthful as an excuse not to take responsibility for whatever cause he is approached for, since no one expects youths to have such responsibilities.
