Chapter 178: Family reunion
A few minutes later, the U.A. Warcraft airship appears as everyone rush towards it to greet the hero council and some IHWO members as they come out. Izuku and Ochaco then hugged their kids before telling them that their aunt Eri, Abbigail, Akumo, and Himanko are also here to join the party along with Ryuku and her daughter, and Hawks and his son, causing the twins to smile as they go hug the rest of their family. Soon after meeting Ryuku's daughter Kanna, and Hawks son Kamali, the twins open more presents until Kouna wants to show Izu and Ochaco the new karaoke machine in the dormitory, causing Hisashi to get an idea and told Cadet 1a to get things ready so they can put on a play for them while they entertain everyone, which also caused Tessie to say ok before leading her fellow cadets inside. The Peanut Gallery then lead the hero council, Kanna, and Komali to their dormitory so they can see the new karaoke machine.
Kanna then became amazed as Hisashi turn it on and explain how it works, causing the hero council to convince the team to sing some songs for them until it's time for the play to begin. A montage then begins as the Peanut Gallery sang each of their favorite songs from the Backstreet boys to Michael Jackson until the montage ends with Kouna telling Hisashi that he can choose one more song and about four people to sing with him, causing Hisashi himself that since he sang perfectly in harmony with Lydia, Sabrina, Kanna, and Komali, he wants them to sing "The answer to our lives" from the backstreet boys. After they sang "The answer to our lives" together, Hisashi, Lydia, Sabrina, Kanna, and Komali took a bow before they set off back to the front of the academy, where everyone is waiting for them to cut the cake.
The twins then get in the front as Kiawe brought the cake to them while everyone sang the real version of happy birthday, which caused the twins to smile broadly before blowing out the candles. Albert then asks the twins what they wished for, causing Kouna to reveal that she wishes for world peace, which caused Hisashi to say that he's not telling everyone his wish. Soon, a montage begins as everyone ate cake and ice cream as some of the Peanut Gallery's friends danced to "Ice cream and cake" from Oro Solido until it ends with Class A115 calling the hero council and their professor inside the academy to talk to them. Soon, Kouna gets everyone's attention so she can make a thank you speech for everyone (especially her comrades, who stuck by her and Hisashi's side when something wasn't right) before thanking Hisashi again for not leaving her on their birthday just like he did on their past birthdays, causing Hisashi himself to get flustered before stammering as Kouna began teasing him. Soon, the cadets told everyone that a play called Madagascar Jr. is about to begin, causing the hero council and Professor Raymond to have a seat with everyone at the party to watch Cadet 1a's play.
