Takeoff

Mistaking a scowling stranger for a criminal, Eraser Head opens the episode trading blows with Knuckleduster in the open street. Binding cloth and footwork keep the older man pressured, yet nothing lands hard enough to end it. The pro reaches for Erasure expecting to switch off some endurance ability, and gets nothing at all, because there is no Quirk in the man to cancel. Realizing he has no legal grounds for an arrest, Shota Aizawa breaks off and apologizes, privately shaken that a Quirkless civilian hits this hard.

Meanwhile Kazuho Haneyama has been combing photographs of every Instant Villain sighting and finds one constant: the jittery salaryman Mario Kugutsu appears in all of them. She Leaps after him while Koichi gives chase on foot, only to be cut off by Rapt Tokage, Moyuru Tochi and Soga Kugisaki, still sore about their beating the previous night. Knuckleduster scatters them with thrown bricks, and Aizawa, day off or not, ties up the stragglers.

Cornered at last, Mario cracks open an All Might figurine to reveal a hidden Trigger needle and jabs it into his throat. His Playtime Quirk swells him into a four armed black giant who snatches Kazuho and Rapt and swings them around the block like toys. Knuckleduster's grappling kick knocks the giant off balance, and Kazuho falls with no surface to push off. Admitting to himself that he chases this work because he genuinely wants to be a hero, Koichi launches from a wall, catches her, and gives her the platform she needs, then rides the villain's own palm to safety on Slide and Glide. Erasure ends the tantrum seconds before a giant foot lands.

Aizawa thanks the old man but warns him off the path he is walking. Knuckleduster counters that he only cleans up what pros cannot, and floats the idea of hitting future criminals before they offend. The detective in Aizawa notes that assault is still assault. The next afternoon Koichi arrives at a schoolyard scrap in armor Knuckleduster supplied, slips into a trash pile, and announces himself as The Crawler, a name Ichimoku Samazu promptly mishears as The Cruller. A Hardening user named Akira Iwako then goes berserk on Trigger nearby, and Knuckleduster pounds his face into an unrecognizable state, denying the police any identification. That evening Naomasa Tsukauchi identifies the drug as Ideo Trigger and refuses to soften his stance on unlicensed heroes, no matter how useful. The internet, for its part, settles on The Cruller and Freaky Fist Grandpa.

Knuckleduster's lack of a Quirk is confirmed on screen when Erasure produces no effect during his fight with Eraser Head, and the two part without an arrest.

Kazuho's photo research exposes Mario Kugutsu as the distributor tying every Instant Villain incident together. He doses himself with Trigger concealed inside a hero figurine and transforms via Playtime, and is subdued by Eraser Head after Koichi rescues Kazuho mid fall.

Koichi accepts a costume and a codename, debuting as The Crawler, and joins Knuckleduster in taking down the Trigger boosted Akira Iwako. Naomasa Tsukauchi names Ideo Trigger as the substance behind the outbreak and reaffirms that vigilantes will be punished regardless of intent.

The episode adapts the back half of Chapter 2 together with Chapter 3, sits in the Vigilantes Beginnings arc, and first aired on April 14, 2025. Kekka Alright opens it and Speed closes it.

Several adaptation changes stand out. Soga's Trigger injection is skipped here because it already happened last episode, and the ambush on Koichi is staged with Rapt swooping down carrying the other two rather than blocking him with his wings. Mario's rampage through the streets runs slightly longer than on the page, and the anime adds Knuckleduster using a second brick on Soga.

Much of Koichi's internal narration is trimmed, including his regret over saving Kazuho, his musings on the gap between pros and ordinary people, and a passage that also removes a brief Izuku Midoriya cameo. The scene where he shows off his scars before receiving his gear is likewise dropped. Added instead are Akira's Hardening visibly switching off once he is unconscious and Kazuho fussing over the rescued baby.
