The story follows Seyi, the youngest person ever to be appointed a court alchemist. Her days were once filled with endless hard work, but that life comes to an abrupt halt when a horde of monsters attacks the royal city. Seyi awakens from a long slumber to find that 500 years have passed. The city that was once her entire world has been destroyed, and she is now free from her demanding duties.

Determined to enjoy her newfound liberty, Seyi decides to travel across this completely transformed world. However, her plans for a leisurely, slow-life journey are complicated by her extraordinary abilities. In the five centuries since she last practiced alchemy, the world's knowledge and techniques have drastically regressed, particularly in the art of potion-making. The potions Seyi casually creates, which she considers ordinary, are seen by the people of this era as miraculous, world-changing items. Instead of enjoying a quiet, anonymous trip, her skills quickly become famous, and she finds herself being revered and treated like a holy saint wherever she goes.

The protagonist, whose full name is Sei Fuhrt, is a genius alchemist who willingly entered a state of suspended animation to escape a catastrophe. Waking up in a future where her former workplace is gone, her main motivation is to explore and live on her own terms. Nevertheless, her kind nature and unparalleled talent mean she cannot help but use her abilities to assist the people she meets on the road. This leads to her unintentionally gathering a group of companions and finding herself in comical situations where the world struggles to comprehend her "divine" power. The manga, which began publication in December 2023, chronicles Seyi's travels as she navigates the gap between her ordinary skills and the future's perception of them, all while searching for the true freedom she desires.
