Chapter 78: The legend of one for all
A few moments ago, after the twins went to Technodrome City with Neito Jr. and Tarafukay, Izuku and Ochaco have everyone on the island to prepare a surprise birthday party for the twins at the IHWO organization until one of the citizens asks them if the twins are always fighting, which caused the couple themselves to admit that Kouna and Hisashi used to be real close when they were four years old until everyone acknowledged Hisashi's intelligence and outstanding achievements before seeing him as the number 1 hero in the world. a flashback montage of Hisashi showing emotions when he's around Kouna began as they show how close they used to be by playing together, looking at clouds together, and doing their own secret handshake. Soon, the montage ends with the twins laughing together as Hisashi rode on his Aunt Pony while Kouna rode on Deku towards a sunset. Tarafukay then told her uncle that Kouna been wanting Hisashi to smile again so they can do all the things they used to do when they were little, causing the rest of class 1a to agree before telling everybody about Kouna's desire to stay by Hisashi's side so she'll protect him from getting killed by a villain just like their grandpa Izenko and Grandma Inko years ago. Soon, the party is completed as Griswell and Akane told everyone that Kouna and Hisashi are coming.
After everybody say surprised, Kouna gets excited while Hisashi just look at everybody emotionlessly as the party begins. Soon, Tetsutetsu told the twins that he and his comrades have been talking with their parents and decided that since today is their birthday, they will no longer be grounded as long as they don't fight with each other, causing the twins themselves to agree to put their differences aside since today is their sixteenth birthday, which also caused everybody to cheer. Soon, Samuel, Trone, Bella, and Annie (daughter of Nelson) arrived with their parents as they give the twins birthday presents before giving them hugs, which caused Kouna to give Bella and Annie a bear hug that almost crushed them. Soon, All Might and Celia arrives and told everyone to gather around so they can tell them how the legendary one for all was created in the first place.
Long ago, after the infamous All for one created the Warcraft of Doom organization, Yoichi Shimura (Tenko's brother) confronted him before vowing to stop him from turning the world into a kingdom of darkness and despair, which caused All for one to get furious before warning his brother that if he gets in his way of stealing one for all, he'll kill him. However, what All for one didn't know is that Yoichi is the one who discovered one for all before making it his power, so he'll face his brother. During the confrontation, Yoichi told All for one about Mario Midoriya, who created quirks in the first place before starting the fight. Before getting killed, Yoichi passed one for all down to Fyet, who then passed it down to Fajin. After years of facing All for one, All Might give four-year-old Izuku the quirk before Inko enrolled him into kindergarten. However, after Izu married Ochaco and have Kouna and Hisashi, he decided that for now on, one for all will no longer be passed down by touching hands or eating DNA. Instead, it will be passed down to his descendants through genes, starting with Kouna and Hisashi. Celia then takes her turn as she told everyone that she's going to tell everyone about what makes the legendary one for all so powerful.
