One hundred years ago, the War of Humans and Demons ended in a crushing victory for humanity. Since then, the defeated demon race has been stripped of their dignity, doomed to a life of slavery the moment they are born. In this cruel world, Liebe is reincarnated as a lowly "Demon" (Akuma)—the very species humans despise most. In his past life, Liebe died in despair after years of relentless bullying. Now, trapped as a "pet" slave for a frontier noblewoman, he faces the same cycle of oppression. Bound by a magical slave contract, resistance seems impossible... until he awakens a Special Eye that sees the fatal weaknesses of any opponent. By combining his unique vision with forbidden magic, Liebe develops a way to temporarily defy his slave contract. He’s done being a victim. If the world sees him as a monster, he will become the greatest monster of all. "I’ve finally become a demon. So why not become the strongest Demon King and give my people hope?" The curtain rises on a dark fantasy of rebellion, where the weakest species rises to claim his throne—and his forbidden harem!
