Princess Claudia's life should be tragic… pushed from a window by her uncle, coldly ignored, and dismissed by all. But when her past-life memories awaken, she remembers she was Adelheid, a legendary witch who once commanded legions of magicians. Now reborn, she refuses to be anything but herself: fabulously powerful and utterly carefree! (Source: Titan Manga)
