Lazy Dungeon Master (Manga) Vol. 4

With the inn open and business ramping up, things are starting to turn around for the Ordinary Cave's nap-deprived dungeon master. Though once the guild catches wind of this new establishment, Keima's humble abode earns itself a new name, the Cave of Greed. Later, when Haku herself stops by for a visit, she offers up some chilling information -- there's another dungeon on the mountain, the Flame Cave! Can Keima avoid clashing with his neighbors or will he and his dungeon go up in smoke?!
