Heartland City

Heartland City (ハートランド・ シティ Hātorando Shitī) is a location in the Xyz Dimension in the Yu-Gi-Oh! ARC-V anime.

History
Heartland was initially a peaceful city, where many enjoyed Dueling. Yūto, Shun Kurosaki, Ruri Kurosaki, Kaito Tenjō, Allen Kōzuki, and Sayaka Sasayama grew up here.

Heartland has a Duel school that trained people to become professional Duelists called Heartland Duel School. This school has four branches that are based on playing cards: Spade Branch, Clover Branch, Heart Branch, and Diamond Branch. Yūto, Shun, and Ruri are from Spade Branch while Kaito, Allen, and Sayaka are from Clover Branch.

Heartland City (and the Xyz Dimension as a whole) was invaded by Academia, who proceeded to rampage throughout the city and seal its populace into cards. During his invasion,Yūri carried out a mission to kidnap Ruri. He did this just after having kidnapped Rin in the Synchro Dimension's City. He was pursued by Yūgo of said dimension. Yūgo witnessed part of the invasion and subsequent sealing of the civilians into cards. Having noticed that Rin's kidnapper had a face similar to his own, Yūgo mistakenly confronted Yūto, who in turn assumed that Yūgo was an agent of Academia. The Duel ended in no result when Shun and other survivors arrived to the scene. These Duelists eventually banded together to help form the Resistance.

In the aftermath of the invasion, Heartland was left in ruins, with every building shown so far being collapsed with broken windows and doors, and the walls of the city having a large hole caused by several "Antique Gear Chaos Giant"'s. The city's colorful ambient turned into a mostly dull grayish tone and a fog covered the entire city.

When the Lancers arrived at Heartland it was revealed that there were still some survivors who weren't turned into cards left and that the Resistance was was already obliterated by Academia students. After Yūya defeated Edo Phoenix the Commander-in-Chief of Academia. , Edo decided to betray the Professor and got everyone under his command to the same. They all then decided to help fix up Heartland and ally with the Lancers and Resistance.
