Potion-danomi de Ikinobimasu!

A supervisor overseeing Earth encounters an error while handling a distortion, resulting in Kaoru Nagase losing her physical form. As a solution, she is reincarnated into a less developed world. Determined to adapt, Kaoru requests the ability to create custom potions at will, along with a magical Item Box, universal language comprehension, and her original fifteen-year-old body. With these abilities, she attempts to build a stable life in the unfamiliar world.
