This year's 29th issue of Shueisha's Weekly Shonen Jump magazine revealed on Monday that the first million moviegoers in Japan to see the My Hero Academia: Two Heroes (My Hero Academia THE MOVIE: Futari no Hero) film will receive a "volume 0" (volume Origin) book. The book will feature a cover and a manga drawn by original manga creator Kohei Horikoshi. The book will also contain a "character description and analysis collection" of characters and original characters who appear in the film, as well as a "secret dialogue" between Horikoshi and One Piece manga creator Eiichiro Oda.

Funimation and TOHO will host a world premiere of the film with English subtitles at Anime Expo on July 5. The film will open in Japan on August 3. Funimation plans to release the film in the U.S. and Canada this fall.

Funimation describes the film:

The climactic finals are over, and U.A. is getting ready for the summer training camp. Deku and All Might receive an invitation from a certain person to go overseas to a giant artificial moving city called I-Island. This island, a kind of “science Hollywood” that gathers the knowledge of scientists from around the world, is holding an exhibition called I-Expo showcasing the results of Quirk and hero item research. In the midst of all this, Deku meets a Quirkless girl named Melissa and remembers his own Quirkless past. Out of the blue, the impregnable security system the island boasts is hacked by villains, and all the people on the island are taken as hostages! Now, a plan that could shake hero society has been put into motion! The man who holds the key to it all is the number one hero and Symbol of Peace, All Might.

New characters for the film include David Shield (voiced by Katsuhisa Namase), Melissa Shield (voiced by Mirai Shida), and Wolfram (voiced by Rikiya Koyama). Melissa is a quirkless girl whom Deku meets on I-Island, and her father David was a friend of All Might in his younger days. David is a scientist who makes hero support items, and Melissa works hard to follow in his footsteps. Wolfram is a leader of a mysterious villain team that aims to overthrow the Hero Society.

Original manga creator Kohei Horikoshi is credited with the original work, character designs, and as chief supervisor. Returning staff members include director Kenji Nagasaki at BONES, scriptwriter Yousuke Kuroda, character designer Yoshihiko Umakoshi, and composer Yuki Hayashi. TOHO is distributing the film. Masaki Suda is performing the film's theme song "Long Hope Philia." amazarashi's Hiromu Akita wrote and composed the piece.
