Chapter 129

Before the patrol begins, the two interns trade hero names. Deku, Izuku offers, and Mirio does not hide his surprise. His own is Lemillion, born from an ambition to rescue a million people. They are heroes now, he says, so neither of them can afford to relax, and Izuku agrees.

Which brings them to the alley, where Izuku stands frozen in front of Eri and Kai Chisaki, the man at the head of the Shie Hassaikai. Kai apologizes for his daughter, who tends to lose herself in her games. Mirio catches up and points out that Izuku forgot his mask, which he hurriedly fixes. While Mirio offers his own apology, Izuku curses himself for revealing that the two of them are acquainted, which makes Sir Nighteye's job harder, and plays casual to patch the damage. Mirio picks Kai as Hassaikai from the mask, and Kai brushes that aside, claiming he simply cannot stand filth. Neither face is familiar to him, and he guesses from their ages that they are new. Mirio confirms it and, asked which office employs them, says they are students out on field training. The two move to leave, and Eri begs Izuku to stay as tears start down her face.

Izuku says plainly that the girl is terrified. Kai answers that she was scolded. The explanation fails, since she has locked herself onto Izuku and will not let go. He asks about the bandages and hears that she falls down often. That fails too. Nothing here reads as natural. Kai politely suggests he stop measuring other families against his own idea of normal, and Mirio tries to steer him out, arguing that people simply differ. But a child this frightened is not something Izuku can walk away from, so he asks Overhaul outright what he is doing to her.

Kai yields, telling the heroes to come along, since the matter embarrasses him. They follow into the alley, Izuku still holding Eri. His daughter defies him constantly, Kai muses, and children are difficult to understand, particularly regarding what sort of person they mean to grow into. Then both heroes catch him easing off a glove with murder in the air around him. Eri breaks away and runs to her father, which stops his hand. Kai apologizes for her tantrum, thanks them for listening to a parent's troubles, wishes them well and departs with her. Mirio catches Izuku before he can follow, noting that the killer intent was aimed at making Eri obey, and asks him to honor Nighteye's instructions, because chasing Kai now only makes him harder to catch later.

Back at the hideout, Kai complains about how sickly Eri has been acting and tells Chrono to run a bath. A subordinate apologizes for letting her slip away. Kai has no interest in excuses and kills him with his Quirk, then instructs Chrono to clear that away as well. As Chrono sets to work, Kai observes that everyone is infected with Hero Syndrome.

He needs Eri to stop being selfish, because his entire plan turns on her. He walks her through a laboratory built for experiments and tells her to quit forcing him to soil his hands. One subordinate begins unwinding her bandages while another reports an incoming call from Tomura Shigaraki, who has an answer ready for Overhaul.

Izuku and Mirio reveal their hero names to each other, Mirio's being Lemillion.

Izuku and Mirio navigate a tense encounter with Overhaul and his supposed daughter Eri, who is visibly terrified of him.

Eri returns to Kai of her own accord, forcing Izuku to let them walk away.

Overhaul kills a subordinate at his hideout and is informed that Tomura has a response for him.
