Jikuu Tenshou Nazca

A kendo student named Miura Kyouji learns that his master, Tate Masanari, is a reincarnated Incan warrior named Yawaru seeking to destroy the world for purification. Kyouji is revealed to be the reincarnation of Bilka, the warrior who previously stopped Yawaru. Yawaru is collecting other awakened spirits to unleash natural powers. Kyouji must confront his identity—whether he is a vessel for his past self or truly Miura Kyouji—and determine which version of himself can best save the world and preserve its future.
