Ayase Jirou, is someone who makes a living by net auctioning things he purchased from people who don’t need them anymore, in other words, a Picker. One day he found a large antique mirror from an old hag’s cellar which was given to him for free. That mirror is actually a portal to another world, allowing him to go back and forth between worlds, much like Kakedashi Programmer. In no time he found an exploit that by selling things from modern world to the other world and vice versa he could get filthy rich in no time at all!
