Awaken My Titan Bloodline In The Apocalypse

Around Karl were mountains of corpses and his army of dismembered mechanics. In this world where he was alone, all he wanted was a peaceful death. He didn't even know how long he had fought, all he remembered was fighting every monster that came his way on the battlefield. With his last breath on the battlefield, Karl was sent to the past without memories by someone looking after him in a corner of the universe. Will he be able to remember the memories he lost and change the fate of the people he cares about, or will the same things happen again? It's my first novel and I'll have mistakes on most points. So I apologize in advance.
