Kulun, a mysterious boy, emerged from an egg found in Baikinman’s garbage box as Anpanman World prepared for its annual Star Festival. Cheerful yet enigmatic, he hatched with no memory of his origins or purpose, seamlessly blending into the community. His days brimmed with playful exploration, forging bonds through wide-eyed curiosity and an innocent charm that endeared him to those around him.

When black stars began raining from the sky, their descent sparked suspicions of a disturbance tied to the Star of Life—the celestial force responsible for the creation and sustenance of all existence. Kulun’s sudden arrival aligned eerily with these cosmic anomalies, hinting at an inextricable link between his existence and the growing imbalance. As Anpanman sought answers by investigating the Star of Life, the crisis deepened, intertwining the boy’s enigmatic emergence with the fate of their world.

Kulun’s story revolves around his tentative integration into daily life and the gradual unveiling of his connection to the celestial upheaval threatening the delicate harmony of Anpanman World.
