Suzukuri Dungeon: Karin in the Mountain

After a thousand-year nap sealed deep inside a mountain, the diabolical demon queen Karin herself is about to be unleashed once more! Meanwhile, the young adventurer Kazuto is in serious trouble. When his whole party quits on him at once, his future prospects in the trade look bleak. But just when all hope appears lost, he receives a helping hand from... the demon realm?! This mysterious lady refers to herself as Fuu—she leads him to a dungeon hidden beneath Mt. Giou, where he finds himself face to face with Karin, the demon queen of legend. Kazuto loses a bet to her, and before he knows it, he’s entrusted with the lofty task of managing the entire dungeon, with absolutely no strings attached!
