# The Eighth Son? That Can't Be Right! Ichinomiya Shingo, a twenty-five-year-old ordinary young trading company employee, goes to bed thinking about work tomorrow. But when he wakes up, he's not in his apartment bedroom—instead, he's possessed the body of a child with questionable reason to exist: the eighth son of a poor nobleman with territory in a remote region. Fortunately, he has magical talent, so he decides to pursue his own path and become independent early. Inheriting the family name and territory is impossible, and so is internal political dominance since he has no experience in either. Why is there anything wrong with earning money through magic and living freely? Well, as is the way of this world, one cannot escape the constraints and entanglements that arise from human affairs. This is the story of such a young man, Wendelin von Benno Baumeister, who has no intention of saving the world. --- *The "Eighth Son" anime has been airing since April 2020.* *The series has surpassed 6 million copies sold.* *The light novel series' latest Volume 31 is scheduled for release on November 25, 2025 (the series continues).* *The "Eighth Son" manga adaptation's latest Volume 16 is scheduled for release on October 23, 2025.* *The "Eighth Son" spinoff "The Eighth Son?
