"During the panel Mr. Takahashi revealed more about the film’s story. The film takes place a year after the conclusion to Yu-Gi-Oh! Duel Monsters. In addition to Yugi and Kaiba you will be seeing a lot of familiar faces on screen – characters previewed included Joey, Tristan, Tea, and even Bakura, all with updated designs."

Design
A number of the characters and elements are given redesigns by Kazuki Takahashi, as well as new ones being introduced.

Characters
 * Yugi Mutou: He was drawn to look more mature and having inherited Dark Yugi's strength.
 * Seto Kaiba: His expressions are closer to the more sinister look that he had when he was first introduced.
 * Katsuya Jonouchi: Jonouchi's expression reflects the maturity he gained from his battles in the original story. As a favorite of Takahashi, he paid particular attention to giving him a nice face.
 * Hiroto Honda: Honda has a much calmer expression.
 * Anzu Mazaki: Anzu continued her career as a dancer after the original story. Takahashi considered this to be Anzu at her cutest.
 * Ryo Bakura: Takahashi considered Bakura to be the most mysterious and consequently the least changed out of the major characters.

Cards
 * "Dark Magician". "Dark Magician" looks similar to it did in Duel Art. Originally, "Dark Magician" was more blue and purple than black. This was because in manga, a completely black character weighs the page down and can be difficult to deal with, but this is not a concern in movies.
 * New "Blue-Eyes": When designing monsters, Takahashi felt adding a lot of lines can make them look cool at the cost of quality, and that simple designs are most beautiful. However, as he was dealing with animation, lighting and other effects would bring out the differences, so he designed this "Blue-Eyes" with a style not used before.

Items
 * Duel Disk: The new Duel Disk, developed by Kaiba Corporation, creates Solid Vision holograms from images in the user's brain.

Production
The film was announced in the West before it was in Japan. 4K Media revealed the film's existence on the official Yu-Gi-Oh! website. They teased that the movie was already in development in Japan and that they were shopping for a distributor in all non-Asian territories.

In Japan, the Mainichi Shimbun newspaper's MAiDiGiTV streamed a video teasing the film, alongside a recap of the history of the near-twenty year franchise. Here, it was revealed that the film would feature Yugi Muto and Seto Kaiba as its main protagonists.

Shueisha's Weekly Shōnen Jump also unveiled a synopsis of the movie: "In the past, Yami Yugi and Kaiba have clashed many times! Yami Yugi, who resides in Yugi Muto's body, and Kaiba will have a Duel that bets their prides and accepts each other's mutual experience."

The forty-seventh issue of Weekly Shonen Jump unveiled two new monsters that will be played by Yugi, "Lemon Magician Girl" and "Apple Magician Girl", and specified that "Dark Magician Girl" will also be appearing. In addition, a new "Kuriboh"-like monster was shown that resembles a matryoshka.
