I Shall Survive Using Potions!

Story:

One day, the supervisor in charge of keeping an eye on Earth was dealing with a distortion when they made a mistake, causing Kaoru Nagase to lose her physical form. Not only that, but they can only give her reincarnation into a different, less culturally evolved world. Not one to take things lying down, Kaoru makes a demand: the ability to manufacture potions whenever she wants, with any effect she wants, and it doesn't end there. She requests a magical Item Box, the capacity to comprehend and speak any language, and the same body she had when she was fifteen years old. Using her newfound powers, Kaoru has to try and make a stable life for herself in a whole new world.
