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?
Ryota is making full use of his newly acquired magic bullets and both his income and value is skyrocketing. That power caught some attention and Ryota receives a request to be the trump card for the new dungeon "Selenium" battle. There, he meets the imperfect beauty Celeste?! Can Ryota survive the ever-increasing quests with his unique skill?!
