Izuku tells Melissa to call him Deku even though she finds the nickname strange. Izuku rushes to the central tower where he meets with Tenya, Shoto, Denki, and Minoru. David admits to stealing his research back so he can restore All Might's powers. Cow Lady, Elec Plant, and other bystanders watch in amazement of a hero they don't recognize. Together they find David Shield inside some sort of vault.
This shocks Izuku because they were both born without Quirks. Izuku manages to evade most of Wolfram's attacks as he shouts it's a heroes duty to rescue those in need. All Might introduces Izuku to Melissa and they quickly get acquainted. The villain knocks Melissa aside but this gives Deku an opening to land a smash to defeat Swordkil. However, Melissa reveals that I-Island's security is on par with 's. He learned about the injury via email, but nothing could have prepare him for this. Melissa brings up All Might but Izuku stops her and asks her not to say anything.
All Might's speech is abruptly interrupted when the I-Island Security System sets off an alarm across the entire island. Ochaco deduces that the villains are trying to lead them somewhere. Eijiro notices his Izuku and his other peers watching from the stands. All of the ladies walk in dressed in their formal attire, much to the pleasure of Minoru and Denki. All Might's voice reaches through the sky and reminds Deku to smile in situations like these. Wolfram tries to shoot Deku but the bullet is sent off course by a swift tackle from David.
He's fine, just stuck in place by his own Quirk. The system also locks the central tower from the outside. All Might reassures him that the symbol of peace is still alive. There is also a special World Premiere at Anime Expo 2018, which takes place in July. The film sold its one-millionth ticket during its fourth week. Back in David's lab, All Might reverts to his weak form and David is surprised at how injured he is. All Might notices Izuku flashing a light at him from the third floor.
The movie is directed by Kenji Nagasaki using a script written by YĆsuke Kuroda. David informs them that his name is All Might, and he will become the world's Symbol of Peace. The movie will be airing on the 27th July 2018. It was directed by Kenji Nagasaki and written by Yosuke Kuroda. All Might scolds Izuku for being reckless with his Quirk. Melissa gives Full Gauntlet to Izuku.
All Might struggles to maintain his form but he continues to believe in his students. Minoru makes a poor decision and opens the door to the main section of the floor. The man who holds the key to it all is the number one hero and Symbol of Peace, All Might. All Might soars through the helicopter, rescuing Dave and sending the villains to their fiery demise all in one motion. Melissa also is like him, quirkless. Residents and tourists alike are allowed to use their Quirks and enjoy the various attractions in throughout the city.
Izuku fights his way through more of Wolfram's henchmen until he and Melissa finally reach the top floor of the tower. Inside David's laboratory, talks to David about how well his daughter is doing on her own research. They speak as he recovers from his injuries. Melissa asks Izuku if he's attending and this makes him realize why All Might made him pack formal clothing. Melissa is actually like the old Deku in a way. David tries to apologize to All Might but Wolfram abruptly appears from the smoldering remains of the crashed helicopter. Katsuki dominates the Villain Attack attraction.
Melissa warns everyone they can't afford to damage the server room by fighting. One of the new characters is supposedly an old friend of All Might so it'll probably not focus in the past too much but use it as a nifty feature to draw fans into watching the movie. Izuku feels guilty that All Might lost his power and now David is acting desperately on that. Deku and All Might receive an invitation from a certain person to go overseas to a giant artificial moving city called I-Island. All For One secretly aided Wolfram's invasion to spite All Might. Izuku refuses to allow him to pass, forcing him to come to blows with Wolfram.
Everyone disperses but Melissa asks Izuku to join her at her lab. Izuku takes a moment to thank Shoto for using his fire and then recalls Melissa's explanation for Full Gauntlet. This goes on for longer than the popular hero would've liked it to, making him late to meet an old friend. The name of the character is Melissa. Melissa reunites with Uncle Might While Izuku overlooks the beautiful scenery, All Might gets swarmed by his adoring fans.
