Cera, the White Demon General of King Deros’ Goblin Society, commands her forces to thwart the protagonists’ pursuit of the relic Quaschika. Her adversarial dynamic with Hiro of the Rando family intensifies when he inadvertently frees her during a skirmish—a gesture she interprets as a chivalrous insult, deepening their rivalry. Among the Four Demon Generals, her demeanor contrasts sharply with Groizy, the Black Demon General, whose unrequited affections she dismisses, and Agyle, whose merciless strategies oppose her principled tactics. Only Bluzon, the Blue Demon General, shares her restraint, mirroring his reluctance to harm a captive resembling his late sister. Cera’s conduct, marked by grudging integrity, underscores her unique position within the generals’ volatile hierarchy.
