A few weeks before Izuku and his twin sister, Izumi, went to the Quirk doctor to see what their Quirks are, the twins' father, Hisashi, brought the two to see a dinosaur movie marathon. However, on their way home, the three get into a bad car crash that sends the car dangling over a ledge. Hisashi was able to save Izumi first as she was closest to him. But before he could save Izuku, the car fell over the cliff into the sea below.
Ten years later, Izumi, while hanging out with two of her friends, Katsumi and Shoka, watch as Katsuki is taken hostage by the Sludge Villain while the Pros on scene are struggling to deal with the situation. Just when things start to look bad for Katsuki, an honest to God Ankylosaurus charges in and slams its clubbed tail into the Sludge Villain's eye, giving Katsuki a chance to breathe. Working together with the Ankylosaurus, Death Arms is able to pull Katsuki to safety just as All Might shows up to finish the job.
After the conflict is over, the Ankylosaurus lumbers over to Izumi, Shoka, and the Bakugou Twins almost as if checking to make sure they're okay. Izumi takes a closer look at the dino and notices its green eyes and diamond shaped bumps on both sides of its faces. The Ankylosaurus finally collapses from exhaustion and reverts back to reveal it to be none other than Izuku.
With Izuku back in their lives, the group is finally happy to become the hero team they always dreamed of being after graduating UA.
One day, Ash ended up in Alola and got a tour of the Pokémon School. There, he ended up making new friends. Mallow, Sophocles, Lana, Kiawe, Lillie, Paldea's transfer student, Liko, and Sinnoh's transfer student, Izuku Midoriya.
Izuku was bullied a lot in his old school because he has the ability to understand Pokémon and was seen as a freak. But his new friends at Alola saw him as anything but. He and Ash became fast friends. As it turns out, he lives with Professor Kukui while he stays in Alola.
How will Ash and Izuku deal with the trials that Alola will throw their way?
And more importantly, what kind of romance is in store for Izuku?
