Chapter 80: Party's over

Izuku and Ochaco then told everyone that they will figure out how the villains knew about the incidents that Kouna caused when she was just four years old before going to see what the twins are doing, which is having a calm conversation with each other and their friends. The couple then smile before walking away as the twins themselves noticed them before Kouna thanked Hisashi again for spending their birthday with her, causing him to say that it's no big deal because it's better to have the same birthday with someone you're close with. Soon, the twins get called by their cousins, so everyone can sing the happy birthday song and cut the cake. After Kouna and Hisashi say ok, their cousins talk about how amazing it is that the twins are finally getting along after their fight at the provisional hero exam. however, they were then interrupted by their aunt Komoria, who has received a vision that she must tell everyone. She then says that according to her vision, Kouna and Hisashi are going to get into a fight that's worse than the one from the provisional exam after Kouna herself discovered a secret about how everyone truly feels about her, causing Izu and Ochaco to look at each other and nod in agreement before telling Komoria that they will make sure that it will never happened when they are around.


Soon, after six minutes of spending time together, the twins talk about how they are going to retake the provisional exam and finally get their hero license, causing Kouna to suggest raiding Chaos Island and take down every member of what's left of the new Warcraft of Doom, which also caused Hisashi to say that then they will be rushing. After Kouna pouted, Hisashi gets a phone call from Bearman asking him to help him and Breegull on a mission to stop an elite team of monsters sent by Team Randall, causing Hisashi himself to say that he's on his way much to Kouna's shock and anger as the flashback of her four-year-old self begging Hisashi not to leave her appears. She then scolded Hisashi for leaving her on their fifteenth birthday, causing Hisashi himself to give her an emotionless look before telling her to calm down because their mentors from their first internship needed him to help deal with villains sent by Team Randall. Kouna then growls before telling Hisashi that she thought that they supposed to stick together through thick and thin, which caused Hisashi to become annoyed and scolded his twin sister for acting like a child. Soon, Kouna is on a brink of tears as she told Hisashi to at least let her help him because she doesn't want him to get killed, causing Hisashi to get mad and told her for the last time, that he doesn't need to be protected, especially by a simple girl like her, which also caused Kouna to get furious as she and Hisashi started arguing in front of everyone, including Izuku and Ochaco. Izu then asked one of the twins' friends what went wrong because they were finally getting along, causing that friend to say that all she heard is that Hisashi is leaving to go on a mission with Bearman and Breegull, which also caused Izu and Ochaco to get mad and marched toward the twins.


Izu then stopped the twins from arguing before asking them what is going on, causing the twins themselves to point at each other and told their dad what was happening at once, which also caused Izu to tell them one at a time. Kouna then told her dad that Hisashi leaving her again, just like he did in every birthday they had together before begging Hisashi not to leave her again. Hisashi then became annoyed and told Kouna that he has to go, so the party is now over, causing everyone to be disappointed as Hisashi get into his car and turn it into an aircraft to get to South America, leaving Kouna with an angry expression until she screams and smash a table into two pieces with her fist. She then stormed into the mansion, causing her mother to go after her with the rest of Class 1a while Izu told some of his comrades to make sure that Komoria's fortune doesn't come true. Izuku's comrades then say right before splitting up to check not only if Team Randall's drones are around, but in case they left something for Kouna to find Izu then went inside the mansion to help comfort Kouna afterward watching his comrades briefly.
