At Walpurgis Royal Academy, Raishin Akabane and his pretty companion Yaya are enrolled to study Machinart-a dangerous blend of magic and technology. Raishin is a puppeteer who's capable of using magic to power up Yaya, his automaton, for ruthless battles that no mere human could ever possibly survive. In the wrong hands, Yaya is a deadly weapon, but the honorable Raishin, despite his mysterious quest for vengeance, dislikes wanton killing.
