My Hero Academia Episode 142: The Story of How We All Became Heroes

The episode centers on the fallout from the discovery of the U.A. traitor, the heroes’ preparations for the coming final battle, and Aoyama’s emotional collapse and possible path forward.

Class 1-A learns that the person who had been feeding information about U.A. to All For One is **Yuga Aoyama**, and the class is stunned that he had been under All For One’s influence since childhood after receiving a Quirk from him along with his parents. Aoyama is taken into custody, overwhelmed by guilt, and sees himself as a disgrace, while the class refuses to abandon him. Midoriya tells Aoyama that he can still become a hero, and proposes using Aoyama’s position to their advantage rather than simply cutting him off.

Aizawa later meets with Aoyama and confirms that the dangerous explosive Quirk used against Lady Nagant was not implanted in him, which allows him to speak more openly with the student. Aizawa also conveys that, even if Aoyama is likely to face punishment, he still intends to support him as one of his students while he remains at U.A., and he discusses a plan with the other adults and heroes. The heroes’ larger strategy is to divide the enemy forces, especially separating All For One from Tomura Shigaraki and dispersing the rest of the villains as much as possible.

Meanwhile, Midoriya and Iida visit the support course in hopes of getting help with their gear, but Mei Hatsume is too occupied with security work to repair their costumes, so she provides replacement equipment instead. Elsewhere, the class and pro heroes continue organizing for the final confrontation, with the students being prepared for battle and the adults coordinating the broader tactical response. By the end of the episode, the emotional focus remains on whether Aoyama can be trusted and whether he can still choose to fight for redemption, while the heroes move into final preparations for war.
