After the raid on the Shie Hassaikai, Izuku Midoriya's life changes forever. Not only does he adopt Eri, now calling him "Papa," but he also receives a mysterious invitation from his long-absent father to visit America. Bringing his twin sister Izumi and his mother Inko along, they set off to reunite with the man they haven't seen in years - hoping to heal old wounds.
While Izuku's away, Class 1-A (plus guests from 1-B, Miraculous Academy, and Honnouji Academy) stumble upon a collection of mysterious suitcases labeled with a band name that's taken the world by storm. When they open them, they discover songs that reveal deep emotions - happiness, sadness, love, and pain - and to their shock, the band members are none other than Izuku, Izumi, Marinette Dupain-Cheng, Ryuko Matoi, and Alix Kubdel!
As the students and heroes listen, they learn about hidden parts of Izuku's heart - his struggles, dreams, and the quiet tenderness that draws others toward him. Soon, many of the girls of U.A. begin to realize how deeply they care for their cinnamon roll hero.
