Chapter 151: What Happened to us?!
Meanwhile back at the destroyed Heights Alliance Apartments, Celia was trying to figure out how to use the rewinder gun while the not so babies look at themselves as six-year-old kids in front of a mirror conjured by komoria. Soon, the U.A. League, Whobert, and Fuego returns home and became shocked because not only they found their building in ruins, but the babies are now six years old. Eri then look at the league and ask them what happened to her and the other kids, causing the league to be flabbergasted until Kota snapped them out of it with his quirk so Izu can speculate that when he got blasted by the age controller machine, the babies must have become affected to it as well. Momo then theorize that even though Izu was having a midlife crisis, he cares for the babies a lot, especially Eri, which caused everyone to understand until Celia and Mrs. Wombat ask them what they are going to do now that Warcraft City is in the air. After Izu told everyone that they will work together to take down the Warcraft of Doom once and for all, he told everyone that they must be prepare for what's next because the Warcraft of Doom cannot be trusted, causing everyone to agree until Celia ask Izu if he can teach her how to use the rewinder gun, so the building can be rebuild. Izu then think for a moment and say that since he's fifteen now, he's going to give the rewinder guns a new name.
Izu activated a secret passageway to his laboratory with a press of a button before leading everyone into it so they can see him make some changes to the rewinder guns. When they reach the laboratory, everyone including Izu's friends and little siblings became surprised because Izu's being keeping a secret about a new laboratory from them. After Kinoko ask Izu what other secrets he's been keeping from them, Izuku told Siri to start the remodeling of the rewinder guns, causing a montage of the process to begin while the bot mights greets the U.A. League, their little siblings, Mrs. Wombat, and Celia. Soon, the process is complete as Izu introduced everyone to the new and improved rewinder rays, which works the same, but since Eri's quirk can work on living beings, it will only be use for buildings. Izu then told everyone that once the building is rebuild, he'll show everyone how to get to the laboratory before leading everyone outside.
Once outside, Izu use the rewinder ray to rebuild Heights Alliance Apartments, causing everyone to be amazed until the building is fully rebuilt. After Mrs. Wombat patted Izu on the back saying great job, everyone went inside so Izu can tell his comrades and little siblings about the Warcraft of Doom's possible scheme to steal one for all, which is building a school for villains, causing his friends to predict their darkest hour if they don't do something about it, which also caused Izu to assure his friends that everything is going to be alright because just like U.A. Academy is a school where people learn how to be heroes, Warcraft Academy is a school where people learn how to be villains, and the best part is that they been at U.A. Academy since they were expelled from the kindergarten center. After explaining one for all to the little siblings, Izu asks his friends if they're still going out together, causing them to look at each other in agreement before Eijiro suggest that since Izu is back to his old self again, they should have a guys' night out while the girls have a girls' night out. Everyone then praised Eijiro for his great idea until Izu pouted and admit that he have a crush on Ochaco, Tsu, Toru, and Momo before saying that he was wondering if they could have a speed date with them, which caused the girls to huddle up while the siblings looks on with interest until Momo told Izu that they will talk it out, which made Izu smile as the guys gives him punches and noogies before heading to the food court to get something to eat.
