HELP WANTEDFollowing 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?!

SHALL WE PLAY A GAME?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?!

HOW TO BEAT A DRAGONHaving 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?

The DM WHO CRIED WOLFWith 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?!

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?

Masuda Keima just wants to sleep. Too bad for him, he's been pulled from comfy sheets into a fantasy dungeon that he's charged to protect. Failing to do so will cost him his life. His only guide on what to do is the personification of the Dungeon Core, Rokuko. But she's a moron who can't even figure out how to get rid of a group of bandits. If Keima ever wants to get some sweet dreams again, he'll have to do all the planning himself!
