@Shersh: I think he got a lot more than he wanted :3 The action was happening in real life, and the memories that he himself, having become so liberated due to the alleged unreality of what was happening, forced the Darkness to "rub his back", and not by the will of a succubus in a dream, are much more valuable. Besides, he will always be able to return to this succubus salon and try again, here.
@Stalker13: he can try as much as he wants, but in this case he needs to sleep outside the house. Who will persuade Aqua to remove the traps? Considering that it is impossible to tell why in fact.
Such a cool service, it's a pity, was not shown in action. But, there, it seems, for men, this is the only reason for existence in this boring city, judging by the latest series. And Darkness has a gorgeous figure, but Kazuma's luck is just at its maximum, a winner in life.
I sincerely sympathized with him...

Absolutely nobody:
Kazuma: you son of a bitch, I'm in business (‿)
