Thor Regus, a boy who lived in the empire, was banished to the territory of the Demon Lord by the hands of his father, the Duke.
The reason was that he could only use [Alchemy] and didn’t have any combat skills.
The empire was a military country, and those without combat skills were discriminated against.
That is why the Empire decided to make him a hostage and sacrifice to the Demon Territory.
This is a story about an exiled boy who transcends Empires and Heroes and transforms the Demon Territory into a civilised power.
