Not much is known about this group except that it apparently came to be formed after their city was maliciously attacked by Duelists from Academia. During that time Shun's sister, Ruri, was captured. Sometime after, Yūto and Shun left for the Standard Dimension, Academia students were able to wipe out the Resistance. Sometime after Yūto and Shun left, most of the Resistance was wiped out, with what survivors (and non-combatants) remaining relocating to the Duel Lodge.

In response, Yūto and Shun began to target students of Leo Duel School. Yūto Dueled against Shingo Sawatari and asked him how LDS was connected to Academia. Shingo responded that he had no idea what Yūto was talking about.
During his Duel with Shun, Dennis explained the story of how he met Ruri among the Resistance members.
When Yūya, Gongenzaka, Shun, and Shingo were accidentally warped to the Xyz Dimension, they wandered through the dilapidated streets and had found a refugee family who told them that most of the Resistance was wiped out by Academia's students. The only known notable members left are Kaito Tenjō, Allen Kōzuki, and Sayaka Sasayama who went in hiding with refugees in the Duel Lodge. However, after Yūya's Duel against Academia's Xyz Dimension Expedition Team's Commander-in-Chief, Edo Phoenix, Kaito and Allen arrived with several surviving members of Resistance to assist Yūya, which led to Mamoru Noro, Academia's Xyz Dimension Expedition Team's Vice Commander-in-Chief, to surrender, followed by the remaining Academia soldiers after their Commander-in-Chief and Tyler Sisters decided to defect from Academia. With this, the Resistance and the Academia in Heartland made peace and were working together to rebuild Xyz Dimension.
