Demon King of the Royal Class

After his untimely death, the author of the novel "The Demon King is Dead" is presented with a stark ultimatum: descend into hell or be reborn within the world of his own creation and survive until its conclusion. Choosing life, he awakens as Baalier Junior, a powerless demon prince whose realm has already fallen to conquerors. Stripped of authority and burdened with a fragile new body, he must navigate a hostile reality built entirely from his own imagination. His desperate bid to flee the ruins of his kingdom takes an unexpected turn when he is inadvertently enrolled in Gradias Temple, an elite academy reserved for humanity's most promising students. Now trapped within the prestigious Royal Class, the former author finds himself surrounded by the very human society that destroyed his demonic lineage. To endure, he must conceal his true identity while entangled in the complex political schemes and narrative arcs he once penned. Armed only with his intimate knowledge of the story, he faces the ultimate challenge: outmaneuvering his own plotlines to secure a happy ending before his secrets are exposed.
