Hachi-nan tte, Sore wa Nai deshou!

Office worker Shingo Ichinomiya wakes to find himself in the body of Wendelin von Benno Baumeister, a six-year-old boy and the eighth son of an impoverished noble family in the countryside. His noble name offers neither wealth nor a useful inheritance, since older brothers already stand ahead of him in every direction.

What changes his future is a rare talent for magic. Under a mage's guidance, Wendelin develops abilities far beyond what those around him expect and eventually steps outside his family's limited world into adventuring, nobility, and politics. Every success creates new opportunities but also responsibilities and alliances he cannot ignore, until being the eighth son becomes far less important than deciding what to do with the position he earns for himself.
