In an alternate historical version of the United Kingdom in the early 20th century, scientists have created a mixture of technology and sorcery known as Machinart, circuits made from spells that are put into objects to bring them to life and give them artificial intelligence. These Automatons were developed as a military weapon and spread throughout the world; the humans in charge of them became known as puppeteers. A puppeteer named Raishin Akabane comes from Japan to Liverpool to study at Walpurgis Royal Academy of Machinart, along with his automaton Yaya. Once every four years, the Academy holds the "Night Party", a competition where puppeteers use their automatons to fight in hopes of obtaining the title of "Wiseman". Raishin, however, enters the school and the competition in order to get revenge on a mysterious genius who killed the other members of Raishin's family.
