Kizoku Tensei: Megumareta Umare kara Saikyou no Chikara wo Eru

貴族転生 ～恵まれた生まれから最強の力を得る～

by Nazuna Miki

Born as the thirteenth prince, Noah was originally in a position removed from the imperial succession, so he freely passed his time in the fief granted to him. However, the Crown Prince died before the Emperor. The imperial succession would be fairly contested among the remaining princes. Noah, being the strongest despite living freely, overwhelmed the other princes and eventually became the Emperor with the most power in the world. (Source: Shousetsuka ni Narou, translated)
