The Mechanical Doll Does Not Get Hurt

Machinart: magic used by automata with built-in magical circuits and their puppeteers.

The highest institution of machinart, the Royal Walpurgis Academy of Machinart in Britain, is about to hold a competition to determine who will become the top puppeteer. It is commonly known as the "Night Party."

Just then, two figures walked through the academy gates.

They were Raishin, a foreign exchange student from Japan, and his partner, Yaya, a girl-shaped automaton.

To qualify for the "Night Party," Raishin decided to challenge the other contestants.

His target was Charlotte, a beautiful girl and a leading candidate to become the next Demon King, nicknamed the "Tyrant Rex"!

But just as Raishin challenged her, an unexpected event interrupted them...
