Arminius of the ancient era stood over mankind with the ability to perform magic. His ability allowed him to triumph over mortal armies and carve a domain for himself. 

Then, the martialists attacked. Their individual strength was lower than that of magicians, but the sheer number of them made them an unstoppable force. In the wake of tens of thousands of martialists and hundreds of thousands of mortal warriors, one lone magician was unable to stand against the tide.

But, the powers of a magician allowed Arminius to escape the cycle of reincarnation, landing him an eon into the future. In the new age, magicians are entirely extinct, and the martialists from the old era have perfected their martial way, allowing them to attain godly powers that far surpass what Arminius was ever capable of.

So, what else should Arminius do except learn their method and use it against them?!

Reincarnated as Andric, he seeks to gain the powers of the martialists and reclaim his position at the throne of the world!

A fossil of a bygone age where magic was rampant and he ruled with an iron fist, Arminius is reborn into a world in which magic is fading. The non-magical revolution successful and his rule long over, he must master the new ways of martial arts to rule anew.
