Suzukuri Dungeon: Karin in the Mountain

Kazuto is an ordinary adventurer who was considering quitting since his friends had left and his job prospects seemed bleak. That was when the Gyungyuska Company reached out to him. Directed by a girl named Fuu, he came in contact with the ‘labyrinth’ and the ‘Demon queen’. But why did an adventurer like him meet and be tasked with her revival? Who exactly is the ‘Demon queen Karin’? One thing led to another and he ended up as the manager of the labyrinth.

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! ...Not the merest fiber of the meagerest thread! Expand your budding labyrinth, and strengthen your squads of fearsome (and cute) demons! Build amenities to shake intruders down for cash, then send them packing with well-placed traps and bosses! Cozy up to your sexy and stalwart companions, and maybe a few dungeon-delving adventurers...! If you plan well and fight hard, you might learn Karin's secrets...?
