遊☆戯☆王ZEXAL
The Xyz Dimension is a dimension where its residents all use Xyz Summoning. It pays homage to "Yu-Gi-Oh! Zexal". Its setting is Heartland City, which serves as the setting of the first half of the third season. Heartland City was reduced to ruin from the invasion by the Fusion Dimension's Duel Academy with the remaining survivors forming a Resistance group based in the ruined Heartland City becoming their base. Before the invasion, there were two sections of the Heartland Duel School called Spade School and Clover School, where both became the main forces for the Resistance group. The Spade Branch was wiped out in a later assault. Kite Tenjo is one of the main characters of "Yu-Gi-Oh! Zexal", who makes a reappearance as a different world counterpart from the Zexal series.
