Imagine an MC that doesn't turn in to a gibbering idiot at the possibility of casual sex and also isn't a borderline/actual sexual offender. What a genius this mangaka is, he's cracked the code.
But @rapeman If I don't like your credits pages what am I supposed to do? Not read them? I'm afraid of this world you're proposing where I am responsible for choosing what content I consume.
