(Various) Welcome!

My name is Yun Fei, and I run a one-of-a-kind pawnshop. It travels between worlds, and here, customers can trade anything they own for anything they want. It all depends on what they're willing to give up. I have to admit, ever since I took over this pawnshop ten years ago, my life has been sprinting wildly toward an unknown destination. I went from human to witch, for one thing. At least now I have an unlimited lifespan, a better figure, and a more beautiful, captivating appearance. Becoming the owner of this pawnshop has also given me endless money and a comfortable life, and I can take anything I want from the shop's forfeited goods. So, that's pretty nice. But the pawnshop is supposed to be inside a pocket dimension that connects to every plane of existence. So why is it that every morning, when I open the door, I find myself in a new world? What the heck is going on? And if changing worlds every day wasn't enough, why are they all so dangerous? And if the danger wasn't enough, why are all my customers such weirdos and chuuni nutjobs? There's nothing I haven't run into. Is it really so hard to close a single deal these days? This story is also known as
