Shu, a spirited schoolboy and overeager kendo student, is whisked off to a galaxy far, far away by an alien SWAT team on snakelike ships. The lovely images of Earth are replaced with the grand and imposing designs of a military world, and Shu's happy-go-lucky life turns much darker. He's hunted, interrogated, tortured, and finally drafted into a sadistic king's army of lost boys kidnapped from worlds all over the galaxy. This show greatly focuses on the use of severe physical abuse to train the soldiers fighting in this world, most of them still mere children and the leader of them all is a blubbering, crazy King.
