With Dragon Suzuki now a permanent fixture in Keima's dungeon (literally), things seem to finally be taking a turn for the peaceful. That is, until Keima is made mayor of the newly established town surrounding the inn! His first order of business -- defeat the wolf-like creature invading his territory. Yet no matter how many golems he throws at it, the beast just keeps on coming! Is this the end for Keima and the Cave of Desire?!

"Come on, kill all those bandits for me already!" "No thanks. I don't wanna do any work." My name is Keima Masuda, and my hobby is spending each day doing exactly nothing... but one fateful night, I was summoned to another world where I met a blonde young girl who I named Rokuko. It seemed that fortune had favored me and I would soon be living a wonderful life free of work. But even though I'm a guy who loves sleeping more than eating, Rokuko demanded that I help her. "Save my dungeon! By the way, since you're the Dungeon Master, you'll die too if the Dungeon Core is destroyed." The dungeon only had one room, and it was already surrounded by bandits. Seriously? It's a checkmate already. I've gotta break out of this impossible situation so I can stop working and just sleep!

Having soundly defeated the hero Wataru (albeit through a less-than-scrupulous method), Keima has saved Rokuko from being whisked away to the Imperial Capital. It isn't too long though until another hero shows up on his doorstep…one that proves to be even more trouble than the last! But even Keima isn't so lazy that he'll ignore someone harassing his staff. It's time to take care of this nuisance once and for all--but how?

I’m Keima Masuda, a Dungeon Master aiming to do nothing all day! That’s the idea anyway, but for some reason I’m the town chief, the pope, and I’ve got a noble daughter under my care. To make matters worse, a pair of beastkin siblings Ichika used to adventure with came to town. Seems like the older brother’s in love with Ichika... and he wants to fight me for her? He’s misunderstanding something, but I won’t let anyone get in the way of my sleep! Time to beat the crap out of him and go back to sle– "Dude! Rokuko’s knocked out!" Seems like it’s not time to sleep just yet. This is volume eight of my own kind of dungeon story! If it means saving Rokuko, I’ll show what I’ve really got!

I'm Keima Masuda the Dungeon Master, still chasing my dream to live a life without work. I finally get home from my trip to the Demon Realm (where I spent basically the whole time as a slave), but now Aidy the Demon Realm's princess is visiting the empire. I knew I'd be forced to give her a tour, but... "Can you do nothing about how dreadfully boring it is here, town chief?" The peaceful empire is simply too boring for Aidy! I have to go hunt down someone for Aidy the battle junky to slay in battle?! This is Volume 14 of my own kind of dungeon story! Let's fix this before I get slain myself!

In my attempts to keep my dungeon running without doing any work myself, I ended up becoming a pope on top of being town chief. That must have made me stand out a little too much, because the Tsia Archduke has a quest he wants me personally to do. I was thinking I'd meet him and turn him down, but the reward is information about the Divine Pillow?! Okay, I guess I'll accept it. "Very well," says the Archduke. "I will accept your marriage with my daughter, Maiodore." Wait a second, where'd that come from...? As I face my greatest (?) threat yet, my own kind of dungeon story continues! Why are so many people after me?!

After claiming victory against Haku in the dungeon battle, Keima invests his winnings in some home improvements. His plan? Build an inn! Naturally, an inn requires capable staff. But before he can make his selection, an especially eager candidate pushes their way to the front! She claims she's a safe bet, but will she be able to put her money where her mouth is? Or has Keima got another headache on his hands? And when will his dream of becoming a dungeon master who never has to work come true?!

With the bandits gone and Rokuko safe once more, Keima decides it's finally time for a break. But his plans to relax are interrupted when a beautiful woman shows up on his doorstep. This woman isn't just anybody, though; she's the Dungeon Core of the imperial city's famous White Labyrinth, Haku! Displeased that her beloved Rokuko is stuck with such a nuisance of a master, Haku challenges Keima to a dungeon battle. The catch? If he loses, he'll be forced to leave and work for her! Will Keima ever be able to catch a break?!

After successfully negotiating with the wolf monster Rin and preventing him from destroying the Cave of Desire, Keima catches word that yet another unwelcome guest has arrived in town. This time it's not a Hero nor a monster, but a high priestess from the Holy Kingdom's Church of Light! She tells Keima that she's willing to destroy Rin for him...but only on the condition that she be allowed to destroy Rokuko as well! How will he fend off this new threat?!

Keima can't seem to catch a break. When an adventurer named Wataru arrives at the Cave of Greed, he's not looking for monsters to slay or a room at the inn. He's looking to marry Rokuko! Once it becomes clear he's not just out to split Dungeon Master and Core apart, Keima decides to put his tricks to the test and challenge Wataru to a game. But this isn't any ordinary game. This one's got golem dice, high stakes, and the dungeon's future on the line! Who will be victorious?!
