Sometimes the only way to move ahead is to take a step back.

An undying warlord... an army of creatures... a universe-hopping amnesiac and the humans who don't trust him...

A man attempts to find himself after the onset of an invasion of hostile extra-dimensional beasts hunting humanity to extinction, with himself as no exception. But in a familiar yet foreign world where just about everyone or everything is trying to murder you, where is there to go? When you perish countless times over, what is there to be done? Follow him from a comatose state to discovering their new purpose in existence: fighting through monsters, human and otherwise, no matter how many times they must die.
