Loner Life in Another World Vol. 5 (manga)

"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?"
