The movie BNHA: World Heroes Mission ( Boku no Hero Academia ) revealed that Ryou Yoshizawa joins the cast as the original character Rody Soul, acting as Deku, Bakugo, and Todoroki's partner on the mission.

The new character's design was created by the manga's author, Kouhei Horikoshi . Although the film uses an original story (with no connection to the manga), Horikoshi will once again be the chief supervisor.
Synopsis
A mysterious organization dedicated to destroying people with Quirks has launched a threat and planted bombs around the world. Professional heroes and those in training struggle to find the bombs. Thus, Deku, Bakugo, and Todoroki encounter Rody, a boy living in a mobile home in the designated Oseon area, and end up working with him.
Furthermore, the film premieres on August 6th in Japan, but there is still no release date for the West. A teaser posted on Saturday revealed that in the film our beloved Deku will be wanted by the authorities, accused of mass murder. In addition, the film will feature an incident involving the entire world. The narration in the teaser states: "the time limit until the global destruction crisis is two hours.".
Finally, BNHA: World Heroes is the third film in the Boku no Hero Academia franchise, following Boku no Hero Academia: Two Heroes, which premiered in July 2018 in Japan, and My Hero Academia: Heroes Rising in December 2019.
