Potion-danomi de Ikinobimasu!

Kaoru Nagase dies because of a divine mistake made while repairing a distortion in space-time and is granted another life in the world of Verny. As compensation, she asks the local goddess Celestine for several abilities that sound perfectly practical to her: a youthful body, mastery of every language, unlimited storage, and the power to create any potion she can imagine in any container she chooses.

She quickly discovers that what seems practical by her standards is overwhelmingly powerful in a less advanced world. Kings, churches, and merchants begin coveting her potions, so Kaoru tries to travel freely and earn a living without becoming anyone's property. Her intelligence and inventive use of potion-making repeatedly save her, but every small intervention leaves political and social consequences much larger than she intended.
