(English: Unbreakable Machine-Doll)
In an alternate history version of the United Kingdom in the early 20th century, scientists created a mixture of technology and sorcery called Machinart, circuits made from spells that were 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 came 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". Rashin, however, enters the school and the competition in order to get revenge on his elder brother Tenzen Akabane, a mysterious genius that killed the other members of their family.
