冷遇された第七皇子はいずれぎゃふんと言わせたい！

I want to make the coldly treated seventh prince get his comeuppance someday!

A man who once lived as an overworked office employee is reborn as Lux, the seventh prince of an empire—scorned as “the incompetent prince” for his lack of magical power and abandoned by his father, the emperor. Shunned even by his royal kin, Lux vows to protect his gentle mother, Sonya, and begins intense training to awaken his hidden potential. Thus begins the rise of the once-neglected prince, determined to make the empire—and his enemies—regret ever underestimating him!
