Chapter 15 — Sinister Truth

At night, Recovery Girl attempts to understand how Izuku's Quirk works, while observing him - still in the medical office after he recklessly pulled out too much blood to feed Tae and Lily - and the other patients in the room. Hatsume arrives then with Recovery Girl's weekly delivery of medical magazines and, upon seeing what the school nurse is working on, notes the similarity to the work of a hero called Nanoman, giving Recovery Girl a hint of where to look for answers.

The next day, Class 1-A returns to homeroom, but for a different reason: therapy. Aizawa arrives - putting a stop to a discussion over Izuku and Tsuyu hugging - and tells them that they need to meet with psychologists to help recover from the previous day's events, but Izuku's presence has been requested at Nezu's office.

Izuku (who is in a wheelchair on doctor's orders) is wheeled by Tae and Lily to Nezu's office. Nezu begins their meeting by stating that Izuku's fears are for naught, and Tsukauchi and the principal reveal that the Nomu was a man subjected to such horrible experiments that he was practically braindead, so Izuku's actions barely amounted to anything compared to what the Nomu had already suffered. All Might - who is also in the room - reassures Izuku that not only he can still be a hero, but in fact shows the spirit of one great hero, even after Izuku reveals he had thoughts of killing Kurogiri. Tsukauchi then makes an offer to Izuku: a chance to intern at the police department for a week. After considering it, Izuku accepts. After All Might gifts him a couple of passes so he can take Tsuyu on a date, Izuku leaves - and the adults begin to discuss what the situation with the Nomu might mean, with All Might declaring he intends to pass his Quirk to his successor that day.

Later that day, Nezu reviews the files on the students' first sessions, paying special attention to the ones from Izuku, Tsuyu, Uraraka, Iida and Kaminari, with Izuku providing an exhaustive list of things he and his classmates could have done that would have ensured a victory for the students. As he finishes the reading, he receives a call: Takeo, Lily's father, has finally been found.

Tropes That Appear In This Chapter:

Does This Remind You of Anything?: Momo's slightly irrational behaviour regarding Lily begins to feel like something less innocent than it is.
Entertainingly Wrong: When Iida tries to put a stop to Izuku and Tsuyu hugging (because PDA bother him), he points at Ochako as someone who is also clearly bothered by it - but her case is because Izuku rejected her the previous day.
"Eureka!" Moment: Mei mentions a Pro Hero called Nanoman when she believes Recovery Girl's work on Izuku's Quirk is actually a continuation on his work. This gives the nurse a hint on where to take her work.
Not So Above It All: When Nezu notices Lily's making faces, he answers by puffing his cheeks and sticking his tongue.
Oblivious Guilt Slinging: Hagakure feels ashamed of herself when Ashido claims she was the best at their part of the fight, because there was several points where she thought of running away.
There Are No Therapists: Averted. Class 1-A receives psychological help to allow them to recover from the USJ incident shocks.
You Are Better Than You Think You Are: All Might and Nezu assure Izuku that he has the spirit of a great hero, and that, contrary to what he has seen during his life, his Quirk should not be considered an evil thing.
