Chapter 221: Class 1a's band rehearsal
Meanwhile near U.A. Manor, class 1a split into groups for their performance, which are the band team, dance team, and the special effects team. After taking a sip of water, Izu join the dance team so they can do the choreography of the song that's going to play for the battle of the band, causing Mina, who is the team leader, to start teaching everyone the dance as everyone but Izu struggles to get the moves right. After Izu gets smacked by Tsu's tongue for insulting his teammates, Mina convinced everyone to work harder on the dance moves before reminding Izuku about giving people insults for doing things wrong, which caused Izu to stick his tongue out and made her snicker.
Soon, everyone continues dancing until Mina's watch starts ringing, which caused everyone to stop dancing as Mina answers it. Gwen then whispers that she and Henry got themselves captured by the Warcraft of Doom, which the villains themselves heard as Hatsume told Henso to take the watch away. However, Gwen and Henry surprised the villains by escaping from the ropes like Suzy taught them before Gwen told Mina that they going to need back up as she and Henry did all the moves they were taught by the league. Izu then walked up to Mina and asks what's going on, causing her to tell her comrades that Gwen and Henry need back up at Warcraft Manor, which caused everyone to react in disbelief before Yuga contact the rest of the league and told them that they need a group of volunteers to help Gwen and Henry defeat the Warcraft of Doom.
Mirio then sighs and say that he, Nejire, and Tamaki will volunteer to help the duo, which caused Yuga and the dance team to sigh in relief before Yuga herself thanked the trio. After Tamaki asks Mirio what they are going to do, Mirio summoned Ultra and told him to take their place until they come back, causing Ultra to say yes sir before acting like a serious guard dog as the big 3 take off to Warcraft Manor with Nejire flying ahead. Soon, the big 3 reached the manor as the duo managed to fend off the brats, Ankha, and Polly. Mirio then prevent Himanko from attacking Henry before sternly asking if he and Gwen forgot to check their blind spot, which caused him to confirm it as he gets smacked by Nejire before being called an amateur. Soon, Gwen told the trio that Abby is using an invention that she built to brainwash everyone around the world, causing Tamaki to tell his comrades to cover him as he went off to destroy Abby's invention, which also caused Abby herself to tell her team to stop the heroes while she protects her invention. However, when she uses a move called lollipop jamboree, Gwen and Henry shielded Tamaki with their shield before launching him toward the invention so he'll use his quirk and destroy the invention much to the villains' frustration. Abby then threw herself to the floor before having a tantrum, causing Gwen and Henry to see why the league called her and her comrades brat 1a before the big 3 gives them a lecture about knowing their surroundings and protecting their blind spots, otherwise they're going to get captured just like they did tonight. After the duo put their head down in shame and apologized, Mirio snaps his fingers so Nejire and Tamaki can take the duo back to King Ollie as Hatsume and Himiko comforted Abby before Atsuhiro told everybody that he and Akumo will make sure that the duo gets their comeuppance at the battle of the bands, which Akumo agrees with.
