My Hero Academia: You're Next

Weekly Shonen Jump revealed a fourth feature in its combined thirty-sixth and thirty-seventh issue on August 7, 2023, and the title followed on January 29, 2024. Japan saw the film on August 2, 2024, Beyond Fest screened it that October 6, and North American theaters took it on October 11.

Tensai Okamura directed, breaking the run of Kenji Nagasaki pictures, while Yosuke Kuroda again wrote, Yoshihiko Umakoshi again designed characters, Yuki Hayashi again scored, Kohei Horikoshi again supervised, and Bones again animated. Several firsts belong to this entry: it is the only title in the series to omit the word "Heroes", the first to run a post-credits sequence, and the first to use separate opening and ending themes rather than one song.

The story slots between chapters 342 and 343, with Episode 143 covering the same window, in the gap separating the U.A. Traitor Arc from the Final War Arc. That placement leaves Yuga Aoyama as Class 1-A's sole absentee, since his role as the traitor had already been exposed; he appears solely in the opening credits. Alone among the four movies, it goes unmentioned in the manga, presumably because its development and release straddled the series' conclusion, though the anime folded the events in by reworking Episode 142's jailbreaker hunt and slipping Giulio and Anna in as cameos. Volume Next, the premiere giveaway, holds Horikoshi's prequel chapter A Piece of Cake, while Yoco Akiyama contributed another prequel, Connect to the Day.

A masked man in a dark room replays All Might's victory over All For One at Kamino, surrounded by photographs spanning the hero's whole career. He watches the retiring Symbol of Peace point at the camera and say "Next, it's your turn", and takes the words as a personal summons to inherit the title.

Japan after the Paranormal Liberation War is a wreck: prisons emptied, heroes dead or retired, civilians arming themselves because they trust no one else. Class 1-A tours the country in three teams hunting jailbreakers. Chasing the villain Ginji Kurau, Deku finds him dragging a hostage, Anna Scervino, whose presence is visibly making him stronger, and a one-eyed stranger named Giulio Gandini trying to shoot her dead. The Gollini Family Mafia arrives to collect Anna, and their boss removes his mask to reveal All Might's face. He drops Ginji with a single punch, hacks every surviving broadcast to declare himself the new Symbol of Peace, and, after the real All Might refuses to bless him, rebrands himself Dark Might. Amplified by Anna, his Alchemy Quirk swallows a city and rebuilds it into a flying fortress, the Symbol of Paradise, with the students and thousands of civilians sealed inside.

Scattered across the fortress's biomes, the teams are picked apart by the family. Deborah's Day Dream drops Shoto's team into wish-fulfillment comas while she tests civilians for compatibility with Anna, and Paulo's Erasure Spot strips Deku of his Quirks entirely. Deku and Giulio fall in together, and once the illusions break the gunman explains himself: he served the Scervino household as Anna's butler, hired because his Neutralization Quirk could suppress her Overmodification, a power that supercharges compatible people and racks the incompatible with seizures, Anna herself included. She made him promise to kill her if it ever slipped past saving. The Gollinis slaughtered her family and took her, leaving Giulio with prosthetics in place of his right arm and eye and his left leg, and his Quirk unusable without that hand. Her ability has now reached Quirk Singularity, and Class 1-A refuses to accept killing her as the answer.

Dark Might turns the fortress toward the U.A. Shelter, intending to erase the heroes who remain. Endeavor's line hammers a structure that repairs itself while Lemillion phases inside to run the evacuation, and the students cut toward the palace. Giulio takes Deborah down with a jet booster hidden in his prosthetic leg, and Deku, Katsuki, and Shoto beat Valdo Gollini until the borrowed face burns away, Deku closing with a chain of Ultimate Moves. Defeated, Valdo recalls killing his own father for calling his worship of raw strength a mistake, and finally understands him. Anna's Quirk then bursts loose, mutating Valdo into a colossus, until Giulio reaches her and finds Overmodification has supercharged the very ability meant to cancel it. She calms, the students destroy the monster and the fortress with it, and Giulio learns he was compatible all along: the overload burned Anna's Quirk out for good, leaving her unable to hurt anyone ever again.

Box Office Mojo credits the film with $32,224,616.

Its distribution marked a break in how the series reached Western audiences, with Toho International taking North America and ending a run of Funimation and Crunchyroll releases, though Crunchyroll stayed on for the English dub.

Toho Animation previewed the opening fifteen minutes at Anime Expo on July 6, 2024, following interviews with the Japanese voice actors for Deku and All Might. Promotion was not flawless: the second key visual initially showed Shoto using his ice on his left side rather than his right, an error corrected shortly afterward.
