What kind of impact would it have if we imported the potion to Earth? ~ + ~ +~ +~ +~ +~ + Wataru, one day, accidentally discovered that he could travel back and forth between another world and Japan. Weird, right? But that's not the end of it.  As he gazed upon a town on the other side of the gate, which still had many undeveloped aspects compared to modern civilization, he realized the potential to make a huge profit. By bringing sugar, spices, coffee, and hygiene products to the other world, Wataru earned a fortune.  However, when he noticed the potions being sold in the other world, he had an epiphany: "Wait, isn't this actually better than what we have on Earth?" He brought these potions, which could heal wounds in an instant, back to Earth. When he made a fortune just from these potions, the fattest grin appeared on his face.
