Lancers

The Lancers (ランサーズ Ransāzu) is an elite group of Duelists in the Yu-Gi-Oh! ARC-V anime formed by Reiji Akaba to defend the Standard Dimension from the Fusion Dimension in an effort to save it from the same tragedy that had fallen the Xyz Dimension.

History
Reiji used a database of Duelists called the Lancers Selection to narrow down his candidates for inclusion in the group. The Maiami Championship then became a proving ground for the formation of the group. When the top eight Duelists in the tournament's Youth Division were determined, Reiji inducted them into the Lancers. Knowing an attack from the Fusion Dimension was coming, Reiji dispatched those eight Duelists to confront the Obelisk Force when they arrived to capture Serena and interfere in the Battle Royal of the Junior Youth Division. Six members of the Obelisk Force were confronted by these eight Duelists, led by Yū Sakuragi. However, all of them were swiftly taken down except for Yuu, who was saved by Yūgo.

According to Reiji, the current Lancers lack the strength to combat Academia. Since the discovery of Pendulum Summoning, Dueling evolved to a new era, which Reiji dubs "Yūya Sakaki's generation". He plans for this new generation to master Pendulum Summoning to combat the invaders more efficiently.

When the Battle Royal ended, Reiji appeared before the survivors and explained his plan and the overall situation. This enraged Yūya, who refused to join the Lancers and attempted to attack Reiji. Reiji suggested they settle it with a Duel instead. Reiji won the Duel, and concluded that Yūya was too naive. He maintained his hopes for Yūya, however, and declared that the Lancers would soon travel across Dimensions.

Later, Reiji and Himika cancelled the Maiami Championship to reveal the Lancers' existence to the world as well as their recent victory against the Invaders. The Lancers were acclaimed as heroes by the world, and Reiji declared that LDS would switch all of its efforts to training Duelists to become potential Lancers.

After Yūya's Duel with his mother, he and Gongenzaka were called by Leo Corporation. When they arrived, they saw the other Lancers gathered inside. Reiji announced that they were having a new member, Reira. Shingo and Shun were both skeptical about Reira being be a threat to their plans, since he was a child and must always be protected. Reiji responded that Reira's ability was almost "equivalent" to the Lancers. Then, after learning that Yuzu was in the Synchro Dimension, Dennis expressed surprise that she survived. Reiji also announced that they were going to the Synchro Dimension to make an alliance with it, as that dimension has never been into wars. Reiji said that the Lancers' Duel Disks were now modified to be able to travel between dimensions and activate Action Field Spell Cards and Action Cards, which were the strongest weapons against the invaders. The Lancers then left the Standard Dimension with their "Dimension Mover" cards and traveled to the Synchro Dimension.
