Episode 66

Izuku's All Might impression earns nothing but scorn. Sir Nighteye picks apart the wrinkles as completely wrong and asks whether the boy means to mock the greatest hero alive, a question that carries weight in an office buried under All Might merchandise. Ordered out, Izuku explains that the face he copied came from the aftermath of the Vinegar Riverbank Incident, and the conversation turns to that case and the interview around it. Mirio frees Bubble Girl from the tickle device, impressed by his junior even in defeat.

Presented with the paperwork, Sir Nighteye lays out how Work-Studies differ from the week-long internships, then refuses to stamp anything. Izuku offers the agency nothing, he says, and words will not change that. The test is physical instead: three minutes to seize the stamp by force so the contract can be signed. Mirio, sent out with Bubble Girl, doubts anyone can beat a Quirk that sees everything coming.

Full Cowl does not help. Every reach is sidestepped, because Foresight lets Sir Nighteye view an hour of a person's future after locking eyes and making contact. He tells Izuku plainly that One For All belonged in Mirio's hands, and the words land hard enough to rattle him. Remembering the training that got him here, and the choice All Might made, Izuku rallies. He ricochets around the room at speed, is dismissed as a discount Gran Torino, and starts hurling books to manufacture chaos his opponent cannot predict. Nothing works, and the clock runs out.

Sir Nighteye calls the whole attempt clumsy, one bad plan pursued to the end. Izuku admits he was steering around an irreplaceable All Might poster that never went on sale. Every piece of merchandise in the room survived the fight, provocations included, and that detail moves the pro more than any of the maneuvers did. He takes Izuku on, though he claims the decision was never in doubt: working beside professionals is how the boy will come to understand that someone else deserves One For All. Izuku thanks him anyway and stamps the contract.

His classmates celebrate the news at Heights Alliance while he keeps the real terms to himself. Shoto tells Katsuki the gap has opened again and they need to close it, which does not sit well. Ochaco laments missing out on Gunhead, Tsuyu on Selkie, and Eijiro learns Fourth Kind takes no trainees at all; only pros with serious records can shoulder a student on dangerous work. Eraser Head underlines the responsibility involved, then informs Fumikage that Hawks has invited him to Kyushu, an offer from the No. 3 Hero that the class finds astonishing and Fumikage accepts. Tamaki wants a word with Eijiro, Nejire with Ochaco and Tsuyu, and the three head straight to the third-years rather than wait.

The Work-Studies begin the next morning. Sir Nighteye's team patrols while pressing an investigation into the Shie Hassaikai and its head, Kai Chisaki, known as Overhaul. Contact with the League is confirmed, criminal proof is not. In an alleyway a small, frightened girl named Eri collides with Izuku, and the masked man she is running from steps out behind her.

Foresight debuts as Sir Nighteye tests Izuku with a three-minute challenge for the stamp, then accepts him despite the loss, hoping the experience convinces him to surrender One For All.

Fumikage receives an invitation from Hawks, while Eijiro, Ochaco, and Tsuyu are summoned by Tamaki and Nejire about placements of their own.

The Nighteye Agency's investigation into the Shie Hassaikai collides with reality when Izuku meets Eri and Overhaul in an alley.

Chapters 127 and 128 are adapted here, in the third episode of the fourth season.

The Vinegar Riverbank Incident is dramatised on screen rather than merely discussed, and the dorm scene about the scarcity of Work-Study offers is an anime addition, as is the mention of Hawks, who is not named until the Pro Hero Arc in the manga.

Sir Nighteye briefs his team inside the office rather than on the street as in the source, and Izuku patrols in his iron soles.
