Roen moves through the Four Emperors Academy wearing the guise of an adorable Pomeranian, yet beneath that fluffy exterior lies Cerberus himself—the ancient sentinel of the demon realm. Bound by an unbreakable oath to his former master, Demon King Marcus, he pursues the legendary Forbidden Grimoire as the key to his lord's resurrection. Behind his disarming, cute appearance hides a sharp-witted schemer with a razor tongue, skillfully navigating the treacherous power struggles between rival factions while pulling strings from the shadows with calculated precision.
