Before I realized, I had become the guardian of a dungeon, a Demon Lord.

How did it turn out like this?

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?

Lazy Dungeon Master

Lazy Dungeon Master

My name is Keima Masuda, and my hobby is doing exactly nothing every day... but one fateful night, I was summoned to another world where I met a blonde young girl who I named Rokuko. It seemed that fortune was on my side and I would soon be living a wonderful life free of work. But even though I'm a guy who loves sleeping more than eating, Rokuko demanded that I help her. “Save my dungeon! By the way, since you're the Dungeon Master, you'll die too if the Dungeon Core is destroyed.” The dungeon only had one room, and the Core was already surrounded by bandits. Seriously? It's a checkmate already. I've gotta break out of this impossible situation so I can stop working and just sleep!
