Chapter 21: Back to school
The next morning, Izuku got out of bed and prepares for school. He then said good morning to his mom and All Might who then revealed that they have been engaged to marriage, causing Izuku to squeal with excitement as he hugged his parents. Soon, All Might and Inko revealed the engagement to everyone else who also got excited and start hugging the couple. The adults get down to business while the kids talk among themselves. Mr. Kaibara then announced their first mission together and declared that they called themselves the U.A. league, which most of the adults agrees with until Mrs. Bakugo ask if the name seems unlikely for them. She then turned to All Might and Inko for advice but see them calling people they know about their engagement and making plans. Mr. Todoroki then get their attention so they can get themselves ready for the mission as the kids set off for school, with the Peanut Gallery going on the same bus.
Izu then recognized the bus driver before introducing his friends to him, causing Mina to remind him that everybody knows about the two incidents. Soon, the bus drove off after the bus driver confirmed that Izu fortunately don't cause trouble on the bus as he and his friends start talking about what's going to happen in school today. Izuku then told everyone that he's been suspicious about the Devil Brats whereabouts and found most dirt about them from the internet by hacking into a secret file, causing his friends to give him a look, which also caused Izu to smile nervously before distracting everyone with a lady with two puppies, which works much to his relief. When they reach the school, everyone went to their class as Momo revealed that she and everyone else knows that he was up to something and they'll discuss it during Lunch, causing Izu to say yes Ma'am with Tenya patting his head. In their classroom, class a then listens to Mrs. Wombat talking to the principal about the Devil Brats and their connection with the Warcraft of Doom. Class a then discuss about one for all and how powerful it is to have villains targeting Izu for it. Izu then theorized that the Devil Brats might have been moles for the Warcraft of Doom before saying that he believes that the reason that they bullied them is to find out which one of them have one for all, causing everyone to believe the theory. Soon, Mrs. Wombat came in and told everyone to sit at their desks for the news.
When everyone is sitting, Mrs. Wombat told everyone that the Devil Brats have been expelled because their parents are part of the infamous Warcraft of Doom, with Hatsume's grandfather as the leader of the villain organization, causing everyone to cheer until the teacher silenced them. A flashback then begins as Mrs. Wombat explained the Devil Brats' intention when they got enrolled to the kindergarten center, which was to find someone with one for all and send lots of villains after him until they're able to steal the quirk and gives it to All for one. The teacher then turns to Izuku and ask him if he would respond to the situation. Izuku then get up and vowed that he and his friends will do whatever it takes to save people with a smile and stopped the villains from taking over the world and destroy peace and harmony. Afterwards, everyone clapped for Izuku before the teacher said that what she meant was to respond to the situation for those who doesn't want to be involved in it but got into it anyway, causing everyone but Izu to tell Mrs. Wombat not to ask that question. When the teacher asked why not, Izu told her that all the haters going to get from him is a middle finger, which he did as he began laughing. Mrs. Wombat then gives Izuku a deadpan look, while some of his friends just shake their heads laughing as she said that it's not funny dryly.
