Yu-Gi-Oh! ZEXAL II takes place right after the end of the WDC Saga. In this new saga, as the curtain falls on the World Duel Carnival, peace has finally returned to Heartland City. But now, forces from Barian World, a world hostile to Astral World, are aiming at taking the "Numbers" and Astral for themselves. In order to protect Astral, Yuma, Kite, and Reginald stand together to combat the Barian threat. Later on, Seven Barian Emperors aim to gather the seven Legendary Numbers and use them to revive the Barian deity Don Thousand to destroy Astral World. In order to stop their efforts, Yuma and his allies go first to acquire them.
