Reincarnated As The Diabolic System

Ethan Cole was once the most promising medical researcher of his generation. When his wife Maya was diagnosed with a rare heart condition, he did not hesitate.

Lucas was once the strongest general in the Demon King’s army, a demon whose strength earned him a position second only to the Demon King himself. Alas, decades of faithful service only earned him betrayal. Left with no way out, Lucas chose to take the Demon King down with him, sacrificing his life in a desperate attempt to end the war between demons and humanity. Except he didn’t die. Instead, Lucas awakened in the body of a human boy twelve years in the past, with his former strength gone but his memories intact.

With his former strength gone, an unpredictable future ahead, and the Hero who was once his enemy now by his side, Lucas must rewrite his fate before the Demon King destroys everything all over again.
