Lazy Dungeon Master (Manga) Vol. 10

DUNGEON UNDER SIEGE The High Priestess Alca has begun her attack on the Cave of Desire, leaving Keima with precious few resources for defending the dungeon. Even his secret weapon, the wolf monster Rin, isn’t enough to stop her! Yet in the midst of this crisis, a more personal battle is taking place between Rokuko and Alca as they duke it out over who really owns Keima’s heart. It’s a fight for survival in more ways than one, but is it a fight Keima and Rokuko can win?!
Series Overview: Masuda Keima just wants to sleep. Too bad for him, he’s been pulled from comfy sheets into a fantasy dungeon that he’s charged to protect. Failing to do so will cost him his life. His only guide on what to do is the personification of the Dungeon Core, Rokuko. But she’s a moron who can’t even figure out how to get rid of a group of bandits. If Keima ever wants to get some sweet dreams again, he’ll have to do all the planning himself!
