Hachi-nan tte, Sore wa Nai deshou!

Twenty-five-year-old corporate employee Ichinomiya Shingo drifts off to sleep while dreading another exhausting day at the office. Instead of waking up in his familiar apartment, he finds himself trapped inside the body of a six-year-old child in an entirely unknown room. As the boy's memories gradually surface, Shingo realizes he has assumed the life of Wendelin Von Benno Baumeister, the eighth and youngest son of an impoverished noble family residing in a remote rural territory. His new father holds vast tracts of land but lacks the administrative competence to manage them effectively, leaving the household struggling to survive. Despite his dire circumstances, young Wendelin discovers that he possesses an extraordinarily rare gift: a profound aptitude for magic. However, this remarkable blessing quickly proves to be a double-edged sword. In a world governed by rigid aristocratic hierarchies and bitter familial rivalries, such exceptional power does not guarantee prosperity. Instead, it invites jealousy, political danger, and unexpected disaster upon a boy who is already at the very bottom of his family's inheritance line. Stripped of his former adult life and thrust into a harsh, unforgiving society, Wendelin must rely on his wits and his magical abilities to forge his own independent path forward.
