Kim Ji-hoon, a South Korean university student, dies from academic overwork and is granted a second chance. He transmigrates into the web novel *Journey to the Throne* as Daevan von Erevos Astherion, the youngest brother of the Emperor but ten years after the story’s end, deliberately avoiding the original plot. For two years, he lives peacefully as the legendary “Eye of the Empire,” covertly maintaining continental stability.
His quiet life ends when Emperor Caelus reveals a crisis: his only son, Crown Prince Reynolt, and the five heirs of the five great noble families Rosalind, Theron, Mirielle, Aldric, and Adrienne form the Privileged Class at the Imperial Arcanum Academy. Their arrogance, cruelty, and scandals threaten the Succession Vote, which could hand the empire to corrupt politicians if Reynolt fails. Caelus grants Daevan absolute authority as Senior Professor to reform the six spoiled heirs.
Daevan employs ruthless teaching methods, humbling them through magical theory, summoning arts, and physical trials. After utterly defeating them in a challenge, Rosalind and Reynolt become the first to submit, followed by the others. Assessing their talents, Daevan identifies their true potentials and begins specialized instruction in summoning, magic, and swordsmanship. As he breaks their pride and rebuilds them from the ground up, the fate of the empire rests on whether these six heirs can become worthy of their bloodlines or doom the realm to ruin.
