This is horrible. Couldn't even get past the second volume. In terms of the "action" genre this is the absolute worst. Within a single volume you have the most powerful warrior in the universe in jail, then out of jail, then fighting for the fate of the world, then getting a slave harem and eating lunch like nothing happened. All of this happens with zero build up or suspense. MC is as dull as a plank of wood with zero personality. Women just pop out of every corner for random fanservice. Reading a dictionary would be more entertaining than this garbage.
