Lemillion

An earlier scene sets the table. Kai Chisaki and Hari Kurono inspect the finished product of their research, ammunition that wipes a person's power away for good, and with All For One removed from the board Chisaki decides the moment has arrived. A second flashback covers the awkward alliance meeting after Twice and Himiko Toga join the yakuza. Chisaki offers an apology over Magne to buy a little trust, the pair refuse to play along, and Shin Nemoto simply forces the details of their abilities out of them, along with an assurance that Tomura Shigaraki has no betrayal planned. Joi Irinaka sees them out with a lecture about respecting an organization he swears will climb back to power.

In the present, Toga's mockery does what the heroes could not. Irinaka loses his temper, his shouting gives away where he is hiding, and a second taunt about the yakuza pins him down exactly. Deku splits the ceiling open with Shoot Style, Shota Aizawa switches Mimicry off, and Sir Nighteye ends the fight with a thrown Hyper-Density Seal while Izuku catches the falling body. Nighteye reads the situation correctly: Irinaka was sold out by his own allies, and the heroes were the instrument.

Deep in the compound, Lemillion catches up with Chisaki, Chronostasis, and Eri. Deidoro Sakaki throws off his balance and Nemoto opens fire, prying out an explanation of Permeation and then using his power to dig at Mirio's motives, insisting the rescue is nothing but self-comfort for a boy who once walked away. Mirio does not bend. Permanently unsteady by the nature of his own Quirk, he shrugs off Sakaki's interference and flattens both men with Phantom Menace, then goes for the boss. He kicks Chronostasis clear by phasing a leg through Eri's face, gathers her up, and promises to be her hero. Chisaki peels off his gloves and admits the girl is no daughter of his, then turns the floor into a forest of spikes he is happy to break her on, since he can always reassemble her afterward.

Cornered but unbroken, Mirio hides Eri behind his cape to spoil Kurono's shot and beats Chisaki down while calling him by name, unspooling the memory of the old boss who refused to back his plan because nobody follows a heartless demon. Nemoto crawls back with the perfected bullets, and rather than waste one on a target who can phase, he fires at Eri. Mirio takes it instead. Quirkless, dizzy, and outmatched, he throws Chronostasis at his enemy and breaks Chisaki's arm with one punch, holding the line for the final third of the fight on nothing but will, until Deku smashes through the wall to join him.

Nemoto's Confession makes its first appearance, and the Quirk-Destroying Drug is confirmed as complete and ready for use.

The Nighteye Squad captures Joi Irinaka after Toga baits him into exposing himself, and Sir Nighteye works out that the League deliberately abandoned him.

Mirio Togata defeats Deidoro Sakaki and Shin Nemoto with Phantom Menace, then takes Eri from Chisaki's grip and reaches him well enough to break his arm.

Chisaki admits Eri is not his child. Mirio is shot with a perfected Quirk-erasing bullet while shielding her and loses Permeation permanently, yet keeps fighting without it.

Deku breaks into the chamber as the episode closes.

The episode adapts four chapters of the manga, running from Chapter 149 through Chapter 152, and sits inside the Shie Hassaikai arc with Polaris as its opening and About a Voyage as its ending.

Several of Mirio's memories of his own past are trimmed away, as is Tamaki Amajiki sensing that something has gone wrong the instant his friend is shot. Nemoto dragging himself toward the fight is also removed, and the narration that closed the moment of Mirio's loss does not carry over. Toya Setsuno stays silent through the recruitment meeting. In exchange, the adaptation grants Mirio extra material against Chisaki after his power is gone.

Copyright concerns led every official subtitle track and the English dub to rename Phantom Menace as Phantom Threat.
