Chapter 17: Kouna's idea
Tarafukay then steps forward and began ranting how unfair it is that the boys get to do dangerous missions, while they get sidelined, causing Dora to point out how extremely talented Hisashi is before telling everyone how he's going to be number 1 in the World Hero Billboard Awards in the future, which everyone but Kouna agrees as Jackura say that they don't stand a chance anyway. Kouna then gets mad before angrily telling her cousins that they are better than they are, and if anyone tries to put them down, then they need to do what it takes to proves them wrong. She then told everyone that it may sound shocking to them, but she managed to do research about the Warcraft of Doom and Chaos Island, causing Madeline to ask her what they can do to convince the adults into letting them join the mission to take down the Warcraft of Doom. Kouna then give everyone a deadpan look before telling them that they are going to take down the Warcraft of Doom themselves, causing the girls themselves to give Kouna a stern glare before Avalon says "really?"
Kouna puts her hands on her hips before pouting as she show the girls how serious she is by giving them a fiery death glare, causing Bea to calm her down before telling her that she felt the same way in this situation. However, they can't do anything that will interfere with the upcoming mission because their quirks aren't strong enough to help the boys and the adult heroes. Kouna then reminded everyone about how powerful their quirks are before she explained how she train herself to get ripped, causing the girls to look at each other until Avalon asks Kouna what she is trying to say. After Kouna give her cousins her determined look and convinced them to make those who doubt their worth as a hero regret underestimating them, Tarafukay told everyone that Kouna is right because since they have been sidelined far too long, it's time for them to make their parents proud by making history. Kouna then smile broadly as everyone cheers before leading them to a quickest route to Chaos Island.
Soon, Kouna led her cousins through Sugar Plum Bay before revealing a secret passageway to Bayside Courtyard, where Kouna prepares a boat for her and the girls to get on before setting off to Chaos Island using Kouna's quickest shortcuts. Meanwhile, the IHWO were just finishing explaining the strategy to the boys of Class 1a before getting things ready to start the mission. Hisashi then contact Siri to ask her for the directions for Chaos Island while his cousins talk to some of the heroes about what they will be encountering. After Siri gives everyone the directions to Chaos Island, the hero council split everyone up into eight groups to make things easier for them. Suddenly, Siri told the heroes that while she was getting the directions, she discovered a problem on their heads, causing Hisashi to quickly realize something before asking Siri not to tell him and his comrades that Kouna is interfering with the mission, which also caused Siri herself to say that Kouna is doing the mission along with the rest of the girls of Class 1a. everyone then became shocked as Hisashi gives Siri an emotionless look before quietly calling Kouna a boob, while the council says that it's even worse that Kouna doing the mission without them knowing. Meanwhile, Team Kouna sail through the seas as a traveling montage begins until they reached the villains' island itself.
