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～

Noah, the world’s strongest six-year-old, has been privileged enough to be reborn as the emperor’s 13th child. What’s more, he’s been overpowered with an infinite level cap and a cheat that stacks the powers of anyone who serves him. But even privilege has its problems—the glittering facade of high society hides a world of conspiracies, schemes, and power struggles.
