Unbreakable Machine-Doll

About the story

Machinart is the magic puppeteers use to control automatons containing magical circuits. Its foremost institution is Britain's Walpurgis Royal Academy of Machinart, where a battle commonly known as the Evening Party is being held to determine the greatest puppeteer, the Wiseman. Now two figures pass through its gates: Raishin, an exchange student from Japan, and his partner Yaya, a girl-shaped automaton. To qualify for the Evening Party, Raishin decides to take an intended contestant's place through a direct duel. His target is Charlotte, a beautiful girl nicknamed “Tyrant Rex” and a leading candidate to become the next Wiseman. But an unexpected incident occurs during the duel.
