I'm Keima Masuda, a Dungeon Master aiming for a life without work. Haku told me about there being a Hell Tournament in the Demon Realm with the reward being the Divine Pajamas, and she even sent me over as an imperial official. She's being so generous I can't help but feel like something's off... And of course, the winner of this year's Hell Tournament suddenly forces me into a fight. "Now then, in accordance to the law, you are now mine." What?! If you lose a duel in the Demon Realm you're the winner's slave? No way! Thus begins my live as a slave. And he's forcing me to train in combat?! This is Volume 13 of my own kind of dungeon story! The demonic hands of forced labor are grabbing for me!

I’m Keima Masuda, a Dungeon Master aiming to not do any work. Several months after bringing the Holy Kingdom under my control, Haku managed to land the finishing blow on Core 10, who previously got away. I thought I was finally about to get all the pieces of the Divine Bedding and be as lazy as I want now that he’s gone, but... “Sorry, Master... Laters.” Ichika’s betrayal leads to our dungeon being attacked! Haku appears to be behind it, but there’s something off about her... This is the final volume of my own kind of dungeon story! It’s one big oyasuminasai!

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!

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?!

Following Keima's victory against the Flame Cave, he gains access to a useful new tunnel and his dungeon becomes more popular than ever. Unfortunately, more guests mean more work, and when Meat collapses while serving customers, Keima is forced to face a long-ignored problem -- he needs more staff! But with his and Rokuko's identities a secret, Keima's best option is using his precious DP to summon a humanoid monster! Has he solved his dilemma or just made things worse?!

I’m Keima Masuda, the Dungeon Master, still chasing my dream to live a life without work. Aidy finally returned to the Demon Realm, but sadly, peace only lasted for so long. “Papa! Mama! Hi, I’m your daughter!” Out of nowhere, Rokuko and I had our first child?! Why?! Isn’t Haku going to kill me now?! I narrowly avoided death by being frank as possible, but in return got stuck solving some problems in Daide. That would have been fine, but Leona had traps waiting for us?! This is volume 15 of my own kind of dungeon story, now starting a school life as a parent!

It's been about one year since I started managing this dungeon with dreams of living a work-free life. A nice and relaxed spring was ahead of me... until I ended up thrown into a three-way Dungeon Battle?! What the hell happened at the Dungeon Core gathering...? Wait, we're on a team with our guardian Core? And Rokuko's guardian is Haku, right?! Uh, given how romantic things have been getting between me and Rokuko, I'm gonna have to say n—  "I look forward to battling with you on my side, Keima." "S-Same to you, ahaha!"  Am I gonna die before the Dungeon Battle even starts?! This is Volume 5 of my own lazy kind of dungeon story!Â
