"FIVE-FINGERED DISCOUNT! ALL TREASURES MUST GO! Haruka's spent a while working his way back up from the dungeon depths with a new companion in tow, grabbing as many treasures as he can along the way. But will they be enough to contend with the mighty monster stampede threatening to wipe out the town he's come to know and...tolerate? And just what kinds of secrets does the mysterious Angelica hide? How might the Class Rep react when she gets a good look at what lurks beneath the Dungeon Emperor's armor? And, most importantly of all, will our hapless hero be allowed to return to his carefree loner life?"

Book 6

"OPEN SEVEN DAYS A WEEK! Having begun his plan to turn Omui into an independent trade hub, Haruka sets about improving the local shopping facilities in record time. But his behavior doesn't go unnoticed, and the lord of an exploitative neighboring territory doesn't take kindly to the idea of Omui going independent. Cue the deployment of an invisible menace... One who relentlessly takes notes! Haruka can't exactly enjoy his loner life with a stalker shadowing him at every turn, but what's a man to do? Our hapless hero decides to just go about his business diving for more dungeon treasures. Surely the situation will just solve itself, right? Right?"
