Chapter 167: Kouna vs Overhaul
Overhaul then makes wild claims about the twins not understanding the true power of All for one's legacy before saying that the cadets was supposed to be used to make the drugs, so innocent people will be turned into instant villains, which caused Charming to coldly scold Overhaul for his villainy as Once-ler prepares to attack again. Overhaul then uses his eight arms to turn the ground into lances and threw toward the twins, causing Once-ler to use her strength to break them before using one for all to counterattack his attacks. While this is happening, the hero council, King Mighty, and some of the Braveworks professors started discussing a plan to help the twins against Overhaul, causing Minmega to get an idea and told Deku to help the twins, which also caused him to fly toward the twins and told them that he's going to help them finish this once and for all. Overhaul then became furious and told the Devil Brats to come and help him. However, just as the Devil Brats was about to help, the hero council immediately attacks them with sheer force from their super moves.
Meanwhile, Deku flew through Overhaul's attack and break it apart, causing her daughter to get an opportunity to use mega slam dive before speculating that due to Overhaul's abilities and appearance, there must be a way to overpower him enough so she and Charming can do one for all: drill Jump one more time. Once-ler then gets an idea and told her dad and comrades to keep Overhaul busy as she grabs Charming, so he'll give her mochi candy to refill her energy. Afterwards, Once-ler uses Delaware smash, Texas smash and Massachusetts smash before using one for all: drill jump with Charming's help. After Overhaul is noticeably weakened. The twins decided to finish the fight with mega finished twin smash, causing everyone to cheer for them as Once-ler jumps up and down as she makes happy noises, which caused the ground to shake with booming sound until she stops and went to Overhaul to handcuff him.
Soon, Hisashi flew down to the ground, which caused everyone to cheer for him as Gretel came to him to reward him with a kiss on the lips. After the hero council announced that the Devil Brats just escaped, Overhaul quickly tries to run away but got stopped by Giant Eri, who then rewinds him back to his normal self so Hisashi can take him to a police car while Kouna shrink herself back to normal. Kouna then gets praised and compliments from everyone before showing them her muscles and abs. Meanwhile, the Devil Brats watches Overhaul being taken away to a prison facility before making their way back to Chaos Island before they get caught by heroes. Soon, the cadets apologized again for getting kidnapped and became hostages for Overhaul, causing the former cadet 1a to assure them that everything is going to be fine now that Overhaul is finally taken care of before King Mighty told everyone that it's time for them to go home, so they can find a way to deal with the Devil Brats next, which also caused the Braveworks students to cheer and follow the dean and professors back to TKOH Island as the Peanut Gallery say goodbye to Class 1a and the IHWO.
