@Willie29 : the first chapter made me think the "Hero" is not out to vanquish evil, but to lead an easy life on the publics expense and bang his harem.
I mean a martial artist who can not punch an opponent because it is covered in mud/slime is not fit to be an adventurer, let along quest against major evils, and the other girl saying she can not psychologically withstand his abilities is admitting she can not handel the later fights.
If the hero cared about defeating the demons they would both be dropped, not even the snu-snu would really be enough since he can get that in other ways while doing the work he is being paid for, and would have noble daughters thrown at him as a reward.
