「You're fired! Peria Fiocle, you who disobey my orders have no place in this laboratory!"

Peria, a commoner working as a court mage, was fired with a single word from her aristocratic superior, Inecto.

What's more, even the golem she had painstakingly built as a hobby was scrapped, and she was expelled from the royal capital.

Peria, at her wit's end, was approached by an adventurer.

Not only did they save her golem, which was on the brink of being scrapped, but they also invited her to join them.

The three who had met in this way had a common goal.

To defeat the colossal creatures known as "Monsters"—beings that had devoured most of humanity and dominated the world, creatures even first-rate mages couldn't vanquish—and to reclaim the world for humanity once more.

For this purpose, Peria's golem is essential.

"I still have dreams to chase. Golem, let's strive together!"

This is the story of a puppeteer, branded incompetent as a court mage, who will eventually save the world—its prologue.
