The Vagabond

After accidentally taking his own life while overworked, a cynical accountant wakes up as Arthur Bolton, the 16-year-old Lord Duke of a decaying duchy.

Trapped in the body of a sadistic, drug-addled tyrant, he must navigate a den of venomous vipers where his own siblings fear him, and powerful mages plot his assassination. To survive, he has to bring the family name back in business, become a mage himself and outmaneuver a treasonous council, all while hiding the fact that he is an imposter from his own loyal, bloodthirsty Sword Knights.

This is the story of the best, and the worst Vagabond.
