Five seconds. One punch. A world champion fell. Then David tore open his enemy's chest—payback for his murdered mentor. Now the deadliest fighter alive is pushing a mop, hiding as a janitor to protect Anna and her little girl. When her ex hurts the child, David steps up. He takes a full punch without flinching. He sends the bastard flying. Then a cyborg attacks. David crushes it with one hand. They think he's just the janitor. He's the God-Fist Champion. And he's done hiding.
