Days Of Future's Past

Primo lived his life believing himself to be an Ordinary healer until the day he accidentally discovered that his "Ordinary" healing ability, is in fact, the legendary ability of time reversal!

Hailed as the unprecedented Knight of all times, he slaughtered his way to the end of the supreme enemy of the human race the Envoy Of The End with indomitable spirit, but his life ended in defeat.

Just when his tale of heroism was about to end bringing the inevitable extinction to the human race, he gathered all of his mana along with his life force as he used his ability to the limits to defeat the Envoy Of The End.

But what reversed wasn't the fate of humanity, but the flow of time itself as he traveled back to the past.

Now, he was still a teenager who left a legend of life in the future. With a chance to save the human race finally in his hands, his legend begins as he becomes a myth.
