One day, on a sunny leisure day, a woman visited my house and asked me if was interested in managing a dungeon along with support offered from a goddess. But of course, I refused. Eh? I shouldn’t ignore a person in trouble, moreover if it’s beautiful woman? No way, that’s too bothersome, 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?
