One day, the supervisor in charge of watching over Earth was taking care of a distortion, when they made a mistake that caused Kaoru Nagase to lose her physical body. Not only that, but reincarnating her into a different, less culturally advanced world is the only thing they can offer to do for her. Not one to take this turn of events sitting down, Kaoru makes a demand: the power to create potions at any time she pleases, with whatever effect she wants it to have—and it doesn’t stop there either. She asks for a magical Item Box, the ability to understand and speak every language, and the same body she had back when she was a fifteen-year-old girl. Using her newfound powers, Kaoru has to try and make a stable life for herself in a whole new world!

After receiving the power to create any potion she wants, Kaoru is sent off to live her new life in a brand new world. Things don’t go exactly as she planned, though, and the truth comes out that she’s friends with the goddess Celestine! Though Kaoru tries to keep her head low despite this (emphasis on “tries”), she can’t help but put her potion powers to use, drawing the attention of both countries she’s already passed through. One thing leads to another, and, well, a war breaks out. With new friends up high and old friends down low, Kaoru has to use her wits to protect them and end the war... and come up with new ways to use her powers while she’s at it. It’s time for Kaoru to put her brand new schemes into action! Just hope she doesn’t read the fine print on her deal with Celes...
