Chronicles of an Aristocrat Reborn in Another World Vol. 1 (light novel)

The light novel series that inspired the manga and anime! A story about a modern man who finds himself reincarnated as a young nobleman with powerful magic.

To his surprise, Cain learns that upon turning five, he'll receive powerful blessings from the gods, each one enhancing his stat abilities to godlike levels. With immeasurable strength, magical prowess, and intelligence far beyond human limits, Cain begins to uncover the vast scope of his powers. As he navigates his new life, he must keep his extraordinary powers a secret while dealing with gods, aristocrats, and charming young ladies. His adventure is just beginning.
