Jeanne arrives like a comet into Montmorency's fractured world, and the show stops pretending to be a serious historical epic the moment she speaks. What you're actually watching is a romance where alchemy and war are just the scenery, where tone whips between devastation and comedy hard enough to give you whiplash. The plot collapses under its own weight halfway through, scattering threads it never picks up again, but if you're watching for the moment these two people realize they're saving each other instead of the kingdom, it hits exactly when it matters.

In 15th-century France, the Hundred Years' War with England rages on. Montmorency, the son of a noble, throws himself into the study of magic and alchemy at a royal school for knights. When France suffers a crushing defeat at Agincourt, the school is broken up, and Montmorency, newly become an alchemist, loses everything and becomes a wanted man. On the run, he crosses paths with Jeanne, a mysterious village girl with something miraculous about her. The story is a historical fantasy that combines action and adventure with romance.
