Unbreakable Machine-Doll

Raishin Akabane, an exchange student from Japan, arrives at the Walpurgis Royal Academy of Machinart with a goal: use his beautiful automaton Yaya to become the world's most powerful mage, gain access to the forbidden arts, and use them to kill a man.

One of the Rounds makes Raishin an offer he can't refuse. In exchange for a festival entry, he'll have to investigate a mysterious puppeteer who eats automatons' hearts right out.

Raishin and Yaya receive some unexpected visitors. Meanwhile, Felix and Charlotte each set out to capture "Cannibal Candy," but their plans have irreconcilable differences.

It's time for the final battle with Cannibal Candy, but is Yaya too wounded to fight?

Raishin and Yaya come back from an exercise session to find a strange girl hanging from the ceiling of their room... and things only get weirder from there.

Raishin discovers the mystery behind Frey's actions, but it's not what he expected.

With Raishin in intensive care hovering between life and death, brother and sister must battle each other on the second night of the festival.

Loki and Raishin form a hostile alliance--or something--to defeat the man who's toying with them all.

Raishin learns about a troubled new transfer student, Charlotte's acting strangely, and someone at the academy is under attack. With all that going on, can even a meddler extraordinaire like Raishin manage to help everyone?

Henriette and Raishin are trapped underground, with a cave-in threatening to happen at any moment. And as if that weren't bad enough, someone else is lurking down there that nobody wants to be stuck in a small, enclosed space with...

One battle ends--but with the promise of many more in store.
