While heading out to meet friends for drinks, Kaoru Nagase suddenly collapses. The deity responsible for managing Earth made an error while trying to repair a distortion in the space-time continuum, which resulted in Kaoru's death. Fortunately, the god preserves her mind and soul, granting her a second chance at life in another world, Verny. To compensate for this divine mistake, Verny's goddess Celestine bestows several blessings upon Kaoru: a youthful body, proficiency in all languages, an item box with infinite storage, and—most importantly—the ability to spontaneously create any kind of potion, limited only by her imagination. However, her powers prove too advanced for a medieval world like Verny. As she tries to enjoy her new life and evade those who covet her abilities, Kaoru travels across different nations—but the fragments of influence she leaves behind may soon accumulate into something out of control.
