Chapter 125: Mei and Nejire vs Merged Overhaul
Special smiled mischievously before giving the villains an ultimatum, which is either surrender quietly or fight Nejire Chan and Mei, causing Overhaul to recall a flashback before his boss became bedridden. Overhaul was an orphan on the streets, who accidentally killed his parents when his quirk manifested until the boss of Shie Hassaikai found him and raise him as his own. The yakuza organization was one of the many villainous organizations that ruled the underworld until the rise of heroes got them shut down. Soon, Overhaul felt that he owes the boss his debt and would often lashes out on anyone who badmouthed the yakuza, which got him into trouble. For years, Overhaul tries to reinstate the yakuza by becoming interested in quirk related drugs despite the boss' warnings against them, until he heard about a boy genius named Izuku Midoriya who built rewinder guns to restore anything and instantly heal up anyone, which caused him to become curious and speculate using the rewinder gun on things that was already restored. He then proves his theory by stealing a rewinder gun and test it out on the boss' chair, which gets him annoyed with Overhaul as he told him his plan to make quirk destroying drugs. The boss then questioned Overhaul's morality before telling him to leave the organization if he won't do their way of business, causing Overhaul to become furious and put the boss in a coma after he threw the rewinder gun in a dumpster. Soon, Overhaul calmed himself down and saw a woman named Tasha using her quirk to help heal a hero from a severe injury, which caused Overhaul to get an idea and laugh evilly.
After the flashback, Overhaul quickly merged himself with Shin and Rikiya until he became a giant monster much to everyone disgust before rushing toward Deku and Eri. However, Nejire Chan quickly blasted him with output: 30 of her quirk before Mei shot a net at Overhaul, causing him to try to get out but trips afterward. Nejre Chan then told Mei to use her gas machine before telling her to give her a gear that let her go beyond her limit without harm to her body, causing Overhaul to try to attack the girls but gets blasted by more waves from Nejire Chan until Mei put a gas machine into the palm of her hand before telling everyone to cover their mouth so she can turn it on. Overhaul then starts coughing before destroying the machine with one of his legs before searching for Deku and Eri until he got attacked by the U.A. League, including Ryuku until Overhaul swat them all away before getting blasted by Nejire Chan's new super move called Nejire flood with help from Mei. Nejire Chan then told Deku to get Labrava so they can help her and Mei finish the fight against Overhaul. Deku then gives Creati Baby Eri before taking Labrava to Nejire before landing on Mei's head to activate support bond while Labrava gives Nejire Chan love. Overhaul then furiously vowed to make the world a better place with the quirk destroying drugs before desperately trying to attack Nejire Chan and Mei. However, Deku made Mei's dynamax cannon giant before giving it to her so she and Nejire Chan can attack Overhaul at once, which works successfully as Overhaul gets blasted by Nejire Chan's Nejire flood and Mei's dynamax cannon before getting himself separated from Shin and Rikiya, who are severely injured after the fight.
Overhaul tries to take Eri away from Momo but got pinned down by Izuku as he handcuffed him before saying a lame pun as he laughs. The U.A. League then take the villains to the police while Izu told his teammates to check the damage for any more villains before flying up to Mei and Nejire to give them shrinking antidotes. All then take Sir Nighteye to an ambulance as he tells him to stay with him before checking on Baby Eri, who fell asleep in Momo arms, causing everyone to go aww. At the hospital, the Peanut Gallery, Ultra, and Eternatus play with Eri until the adults came to them and told them that it's time to say goodbye to Sir Nighteye. Mirio then became devastated as he ran to Sir Nighteye's room and beg him not to die, which Izu and All Might agrees. soon, All Might's ex-wife Celia and kids watched solemnly as Sir Nighteye uses foresight on Izu one last time before saying that he and his friends will be the greatest heroes in the world. He then gives everybody an encouraging speech as they cry before dying happy to be part of the U.A. League. Audrey and Nelson then quickly comforted Izu, Sam comforted Inko, and Tyler and Celia comforted All Might as they look at Sir Nighteye with tears in their eyes.
