One day, the supervisor in charge of Earth was taking care of a distortion, when they made a mistake, killing Kaoru Nagase! Not only that, but reincarnating her into a different, less culturally-advanced world is the only thing they can offer as an apology. Not one to let a good opportunity pass her by, Kaoru starts loading up on cheat powers: the power to create whatever potions she wants whenever she pleases, an Item Box with infinite storage, the ability to understand and speak every language, and the same body she had as a fifteen-year-old girl. Medieval life may be a challenge, but Kaoru is determined to survive!
