Before the summer training camp, All Might fondly watches a special focusing on his time in America, and reminisces about his good friend David Shield.
Later, Midoriya, Uraraka, Iida, Todoroki, Asui, and Bakugo participate in a special training exercise led by the U.A. faculty. The group of six is tasked with determining the appropriate response to a specific crime scene — a villain (played by All Might) has broken into a jewelry store and has three hostages (a store employee played by Cementoss, and two customers played by Midnight and Present Mic). Todoroki distracts the villain with a phone call while Uraraka scopes out the scene. Bakugo gets impatient, charges straight in, and blasts open the door, only to find the villain supposedly murdered with a knife. The students decide to interrogate the hostages, but conclude that they are unlikely to have killed with theft in mind. Midoriya suggests that the villain clashed with an accomplice, but this possibility is shot down when Iida announces the store is sealed and empty. After wondering why the villain would bother to barricade himself in the store when he already had the loot, Midoriya concludes that Midnight was the one who called the police, having seen the villain's actions from the outside. She entered the store anyway because of her relationship with the villain, but the villain killed himself in order to protect her.
Aizawa interrupts and commends Midoriya's deductions, but announces that the six of them get zero points because they failed to notice that the villain was actually playing dead the whole time. Iida realizes that the villain did not kill himself to protect Midnight, but rather saw it as an opportunity to escape.
Back at the faculty office, All Might finds an email from Melissa, David's daughter, imploring him to visit I-Expo on I-Island. All Might rushes to Midoriya and invites him along.
Tropes:
- Continuity Nod: All Might's villain costume is the same one he wore while posing as one in the Save! Rescue Training! OVA.
- Driven to Suicide: Midoriya deduces that the villain killed himself to protect his lover Midnight. Subverted when it turns out that the villain actually faked it so he could escape.
- Filler: Most of the episode is entirely anime-exclusive and give Midoriya and other students a new situation when dealing with a villain attack. The rest is a lead-up for the My Hero Academia: Two Heroes movie.
- Hostage Situation: Invoked with the rescue exercise that the teachers set up. The villain has three hostages, and the heroes-in-training have to figure out the best way to deal with it. Also double subverted since as soon as the students charge in, the situation changes to a locked-room murder mystery... but the villain set that up so he could escape.
- Large Ham: All Might is obviously having way too much time playing the villain, especially when he escapes at the end of the episode while cackling. Present Mic also really gets into playing a musician whose every answer to a question is over the top (Midnight and Cementoss tell him to tone it down the next time they run this scenario).
- The Living Dead: When playing dead, All Might (actually the villain he's playing) reacts when Tsuyu accidentally tickles his nose. Subverted and lampshaded when it turns out the villain faked his death and Aizawa points out the students thought it was this trope when it was actually a vital clue.
- Locked Room Mystery: The entrance is surrounded by policemen and all the other exits are sealed — so whoever killed the villain must have been inside the jewelry store.
- Mistaken Death Confirmation: Played for Laughs. Six of the students are doing a special class, wherein they have to act like pro heroes and investigate a crime. The "villain", played by All Might, is found murdered on the floor. When Asui checks to see if he's dead, he
Corpses. They assume he's breaking character and move on, only to fail the lesson because this was meant to be a clue that their villain wasn't dead, resulting in him running off laughing. - Motive Misidentification: The students conclude that the villain killed himself so Midnight would not be affected by her association with him — but it turns out that the villain just pretended to commit suicide to distract them and happily takes off given the opportunity.Uraraka: But what about their love?!
[...]
Bakugo: There was no love! - Mythology Gag: Midnight's and Present Mic's outfits are their civilian wear from manga supplementary materials and My Hero Academia: Vigilantes.
- Never the Obvious Suspect: Tsuyu points out that it was unlikely that any of the hostages killed the villain, since they would be immediately be suspected as soon as the murder came to light.
- Out-of-Genre Experience: Downplayed. The meat of the training session is a murder mystery, but it is book-ended by events that would otherwise not be out of place in a superhero shonen.
- Playing Possum: All Might as the villain was playing dead and bolted while the students stood around deducing the mystery. The students score zero points because they assumed that it was All Might himself breaking character instead of the villain he was playing.
- Scooby Stack: Uraraka, Midoriya, Tsuyu, and Iida look out at the crime scene from the alleyway this way, hinting towards the incoming mystery.
