Ryota Sato gets the surprise of his life when he’s suddenly transported into another world and nearly clobbered at the hands of the young, pretty adventurer Emily Brown. This new world revolves around defeating monsters and profiting on whatever they drop—food, money, items, etc. Unfortunately for Ryota, he has no skills to speak of…until he learns he has the ability to get rare drops! Suddenly his luck turns around…or does it?

Having a hunch that the root of the problem lies in Nihonium, Ryota goes with Alice to conduct an investigation. Waiting for them there is the dreaded Dungeon Master of Nihonium…!?
