Sinopsis
One sunny leisurely day, a woman visited my house and asked me if I were interested in managing a dungeon along with support from goddess. But of course, I refused. Eh? Shouldn't I ignore a person in trouble, moreover if it's a beautiful woman? No way! That's too bothersome, and why do I have to do that? I'm perfectly satisfied with my comfortable life now, throwing it away is just overly stupid...sigh, fine, so it's go to another world, become a dungeon master, manage a dungeon, and deal with the mana circulation problem? Understood, but how to do it?
