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!

Things don’t go exactly as she planned, though, and the truth comes out she’s friends with the goddess Celestine!

Now it’s time for Kaoru to put her brand new schemes into action!

Kaoru has been reincarnated in another world and receives a cheat ability that allows her to create potions as an apology for her death.

Kaoru had been granted cheat powers that allows her to create potions at will. But using her potion powers wherever she goes is hardly inconspicuous. Fernand, the crown prince of the Kingdom of Brancott, who convinced himself that he's bound to Kaoru by fate, had come chasing after Kaoru after she had created miracles in the Kingdom of Jusral. But by the time he arrived, Kaoru was already gone... Meanwhile, Kaoru was busy eating raw fish as she pleased, fighting off bandits, and more! Volume 4 of the popular series is now available!

Kaoru gets reincarnated in another world and receives cheat powers that allow her to create potions.

While all this is happening, someone sets their sights on Layette. What will the enraged Kaoru decide to do…? Will she never get the peaceful life she wishes for? Surely she can resolve all these problems with her cheat potion powers!

The Kingdom of Balmore is in trouble. Kaoru goes back to learn more, but she gets dragged into a succession conflict between the princes of Brancott.

Times may have changed, but not the trio of girls known as KKR! Kaoru, Kyoko, and Reiko have punished Roderich, the arrogant and corrupt Relinas Trade Company branch manager, and he’s now looking to get back at them—both overtly and behind the scenes.
