Chapter 139: The Devil Brats' return
Meanwhile, back on Chaos Island, the Devil Brats are having a meeting to strategize a plan to kill the Peanut Gallery and destroy the hero society. Weather Girl then suggest planting a nuclear bomb somewhere so will blow up the entire island, causing everyone to agree with the plan before clapping for her, which also caused Randall to ask Nelson if he still have the bomb that was originally going to be used eleven years ago. After Nelson say yes, the Devil Brats all laugh evilly as he revealed the bomb before explaining that the bomb's explosion is big enough to destroy TKOH Island. He then reminded everyone that since it's Parents' Day at Braveworks, they are going to put the bomb under the school, so nothing but the island is destroyed.
Soon, the Anti-hero Squad got into their airship and set off for TKOH Island as they discussed how are they going to complete their mission without getting caught. Soon, after a few suggestions, Hector told his team that his idea is to put on disguises so they can hide the bomb under Braveworks Academy. He then explains the steps to destroy TKOH Island with everyone on it, which is Step 1: go to Braveworks Academy unrecognizable. Step 2: use an invention to drill underground and place the bomb right under the academy itself. Finally, Step 3: get off the island and watch it blow up with everyone on it. After everyone clapped and cheer for Hector's plan, Tabitha told everyone that before they go, she needs to go to the bathroom, which caused the boys to give her a brief annoyed look as she went to the bathroom.
Meanwhile, the Peanut Gallery have some of their peers and professors helping them build the stage near their dormitory since the school is closed for the festival. Hisashi and Gretel then told a few of their fellow students that Wendall wants the instruments to be put backstage until they are ready for their performance. Soon, Vivid and Lolli told everyone that the parents are here, causing everybody but the professors to run towards the academy entrance to greet them. Class A113, and Class A114 then look around to see other parents being greeted by their kids and professors until someone say that the U.A. Warcraft airship is here. Soon, the airship landed as the Peanut Gallery's parents come out of it as everybody cheers because not only most of them are number 1 in different states, but the hero council and king and queen of the United Kingdom are on the island. Ochaco then ran to the twins to hug and kiss them much to Hisashi's embarrassment as the council greeted the professors and dean before Gwen ask King Mighty and Professor Goldenwing about the triplets' progress in school, causing Professor Goldenwing herself and her colleague to tell the council and the king and queen their kids' grades and progress before suggesting things to improve their flaws. Professor Blackwell then told everyone that Kouna's strength will give her major advantages against overpowered villains, but she needs to work on using her head to make better strategies and plans. For Hisashi, just like back on Harmony Island, he is exceptional in everything because of his intelligence and calm nature. However, due to his lack of strength along with his defeat against Kouna during the sports festival, people are starting to see him as a coward who is weak. So, to prevent any further shame, Hisashi need to start working on getter stronger while Kouna need to work on making intelligent choices instead of reckless ones. Suddenly, Walter told everyone that they need rope for Mia so she'll be able to fly during the performance, causing everyone to say that Kouna can handle it, which also caused Hisashi, Drake, Gretel, Sam, Patricia, Plunderin, Celia, and Thomas to look around until Izu say that she's showing her mom around campus.
