Rebirth of the demon king

After centuries of ruling the demon realm, Demon King Asmodeus, the most powerful being in existence, longed for something more: a simpler life, free from battles and bloodshed. Through an ancient ritual, he sacrifices his immortal power and reincarnates as a human. Now reborn as Lucian Arden, the youngest son of a noble family in the peaceful kingdom of Arlanor, he finds himself in a world of humans—an experience both thrilling and strange. With memories of his past life intact and a mysterious System guiding him, Lucian sets out to explore the human world. But the kingdom is not as peaceful as it seems, and his journey will bring him face-to-face with demons, conspiracies, and destiny itself.
