Miura Kyoji, a devoted kendo student, learns that his master, Tate Masanari, is actually Yawaru, a reincarnated Incan warrior intent on destroying the world to purify it. Kyoji discovers that he himself is Bilka, the warrior who previously thwarted Yawaru’s schemes. Yawaru has assembled other awakened spirits to unleash the forces of nature. Faced with this revelation, Kyoji must confront his own destiny and decide whether he is merely a vessel for the reincarnated soul or the true Miura Kyoji, who will be best equipped to save the world and the future he knows.
