In the meantime Suikyo, Hayate, and Renge seek a bandit hideout whre the swords came from. By a twist of fate, the swords were made from the meteoric metal that protected the Makaraga on its trip through space. Thus, everyone converges on Kakugyo as he works his plans for conquering Japan. Renge bears a secret weapon - the Tao - a gift from one of the alien women who died of her wounds in Renges arms.
There is quite a bit more to the story that is surprisingly rich for an action film. Amemiya spends a great deal of attention to making the setting a believable 16th century Japan, and then overlays a science fiction flavor, and does this without sounding a false note. Character development gets a surprising amount of attention. Of course there's plenty of sword fighting and flying parts. All of these compontents are carefully balanced.
Of the three major Kieta Amemiya films, Moon over Tao has become my favorite. Admittedly, It lacks the space opera silliness of Zeiram II, and the non-stop special effects of Kakaider. But on the plus side is the well crafted plot plot and believable acting. For those of us who like special effects, there's magical spellwork, alien costumes, and a superb monster. Amemiya demonstrates that, given the necessary resources, he can produce a superior product.
