In the vast Land of Kings, Kain and his sibling Luna grow up in the Moon Clan of Sea City, having depended on one another since they were small. At the ceremony that makes Luna clan leader, a force tied to the family curse bursts loose and kills everyone there except Kain. With the Judges pursuing him, he escapes the city and meets the mercenary Kuang Tie, and the two set out for the Divine Realm to confront the gods. A follow-up to the earlier Rongyao Zhi Zhang season, this four-episode ONA blends fantasy, action and adventure.
