Chapter 91: Breaking out
Kouna look around her cell and try to use her strength and one for all to escape, but the villains weren't kidding when they say that not even she can escape the tower, which caused her to start crying as flashbacks of Hisashi smiling begins. Soon, Wanda came out of her container and offer her help to get out of the tower, causing Kouna to wipe her tears before getting an idea. She then contacted Siri through her watch and ask her for a way out of the tower of Graveyard Hollow, causing Siri herself to analyze Chaos Island before telling her that there are hidden passageways on the island, so she must use her brain if she wants to escape, which also caused Kouna to be annoyed because she hates using her brain. Soon, after reluctantly deciding to do it, Kouna managed to find something sticking out of the wall before telling Wanda to use flamethrower, which caused her to listen as the wall explodes and revealed the first hidden passageway. Kouna then gets overly excited until Wanda barks at her to calm down.
Kouna and Wanda then went through the hidden passageway as Team Randall watches her until Timmy suggest that they go beyond, plus ultra, causing his comrades to agree before setting off to go deal with Kouna themselves. Meanwhile, Hisashi got his team ready until League 1a came in to see if everything is ready. Eri then told everyone that Kouna contacted Siri for the first time, causing Class 1a and their peers to be amazed as Otto speculates that it's more serious than they thought if Kouna needed help from Siri, which also caused Tenso to agree before telling everyone that they are going to follow Hisashi throughout the mission until Kouna is back home where she should be. After everyone say right, Hisashi quietly lead everyone to the harbor of Grand Central District to start the mission to bring Kouna back home. Back at the tower, Kouna and Wanda went through another hidden passageway until they reached an area where Kouna can finally use her strength to make a path. Afterwards Kouna and Wanda finally made it out, which caused them to cheer happily until they were surrounded by ghost monsters.
Kouna then gives the monsters a boisterous smile before trying to punch. However, it didn't work, causing the ghosts to laugh until Kouna give them a deadpan look and told Wanda to use pyro ball at them. After defeating the ghosts, Kouna and Wanda quickly ran through the district as more ghosts tries to attack them, which caused them to go find a vacuum cleaner and suck them up. Soon, a montage begins as Kouna and Wanda went through puzzles and mazes to get out of Graveyard Hollow until they finally reached the final puzzle. To solve the final puzzle, Kouna and Wanda must guess the songs from Michael Jackson, the Backstreet Boys, and Rhianna. Fortunately, Kouna got most of it right because she's been listening to a lot of Michael Jackson and the Backstreet boys songs, causing the exit to be revealed as Kouna and Wanda made it out until they heard evil laughter and slow clapping from Team Randall and their goons.
