The beloved magical-girl fantasy by the creator of Full Moon and The Gentlemen’s Alliance +!

High school student Maron Kusakabe has a secret: she’s Phantom Thief Jeanne. She sneaks into private art collections to steal paintings in which demons reside. Jeanne’s task is to seal the demons before they can devour human hearts. So far she’s been able to evade the police on her midnight outings, but now another thief has come onto the scene—Phantom Thief Sinbad—and he’s trying to take the paintings before she does!

Maron has been betrayed by someone she loves and can no longer transform into Phantom Thief Jeanne. Rejecting the offer to join forces with the Demon Lord, Maron is sent back to the fifteenth century to save the source of her power—Jeanne d’Arc!
