It's nearly the end of the century, and one girl has been breaking the news: Kaitou Jeanne, a phantom thief supposedly sent by God, has been stealing paintings all around the city. Her real identity is Maron Kusakabe, a 16-year-old rhythmic gymnastics enthusiast and student at Momokuri Academy— something unknown to all, even her best friend Miyako Toudaiji, who is in charge of the police chase for Jeanne. Hidden inside the paintings Maron steals are demons sent by the demon lord, who plans to weaken God's power by having his minions possess human hearts. Assisted by the minor angel Finn Fish, it is up to Maron as the reincarnation of Jeanne d'Arc to assume her alter ego, hunt down the cursed paintings, and seal the vile demons away. However, the tough job of balancing this duty with her lonesome high school life only proves more challenging when a mysterious new phantom thief makes his appearance—Kaitou Sinbad.
