A young boy called Tadashi Ino is chosen to be a "Kirin Rider" -- one who protects virtuous things from evil spirits. He's immediately put to the test by Lord Kato Yasunori, a malevolent force who sows chaos and destruction in the countryside. As young children go missing and evil mechanical monsters attack, Tadashi must retrieve a mythical sword from the Great Goblin to save the populace. Standing in his way are mountain-dwelling ghouls.
Four fallen gods are responsible for the environmental disaster that engulfs their land. When a human accidentally takes one of the god's powers, he must train to be one of them, either to become their savior or to bring about their ultimate doom.
