I'm Keima Masuda, a Dungeon Master aiming to not do any work. Several months after bringing the Holy Kingdom under my control, Haku managed to land the finishing blow on Core 10, who previously got away. I thought I was finally about to get all the pieces of the Divine Bedding and be as lazy as I want now that he's gone, but...

"Sorry, Master... Laters."

Ichika's betrayal leads to our dungeon being attacked! Haku appears to be behind it, but there's something off about her... This is the final volume of my own kind of dungeon story! It's one big oyasuminasai!
