The 8th Son? Are You Kidding Me?

Ichinomiya Shingo, an ordinary twenty-five-year-old office worker, wakes up one day as Wendelin, the eighth son of a poor noble family in the countryside. Frustrated by his lack of inheritance rights and political savvy, he feels trapped-until he discovers his talent for magic. This follows his journey as he uses magic to carve out a place for himself, not to save the world, but simply to survive and break free from loneliness. Yet no matter how hard he tries, he can never fully escape the expectations and constraints of the society around him.
