Surviving in Another World with Magic Potions!

Due to the administrator's failure to correct the distorted world, Nagase Kou lost her physical body and could no longer return to her original world. She could only reincarnate into a more backward world. Unable to bear being thrown into such a place, Kou made a request, desiring an ability to 'freely create any kind of medicine' and also receive an item box, the ability to understand languages, and a slightly rejuvenated body. And so, the 15-year-old girl, Kou, uses the potions she creates—magic potions, with the goal of a stable life and begins her adventure!
