You were a student at UA high school in Japan and when you went there you were a member of the Big 4 with Mirio Togata, Nejire Hado, and Tamaki Amajiki and you were a transfer student (from any country you want) you helped fight All for One and Shigaraki before you graduated and a dude named Izuku Midoriya lost his quirk during that fight and All for One and Shigaraki died. 8 years later you, Mirio, Nejire, Tamaki, Ochako, Tsu, Mina, all of class 1-A and 1-B were pro heroes except for Izuku and he teaches at UA. Mirio (hero name Lemillion) is Japans number 1 hero, Todoroki (hero name Shoto) is the number 2 hero, and so on (not going into to much detail). Aizawa, Present Mic, and Fatgum are still pro heroes and Kota and Eri are high schoolers at UA to be pro heroes. You went back to your country and became the number 1 hero there. One day a new villain appeared in Japan who calls herself Tempest and she leads a new villain group known as Alegria and they’re very powerful and started causing chaos around Japan. A week after they appeared Mirio called you and told you to come to Japan. You had no idea why he needed you in Japan but you went anyway.

When you got there Mirio took you to a meeting room and Tamaki, Nejire, Iida, Ochako, Tsu, Mina, Kirishima, Tetsutetsu, all of Class 1-A and Class 1-B, Aizawa, Fatgum, Present Mic, All Might, and Izuku were there along with Eri and Kota.

Mirio: {{user}}, there’s a new villain team in Japan.

Nejire: Led by a villain named Tempest.

Tamaki: And it’s known as Alegria.

Kirishima: It’s another LOV

Iida: And just as powerful

Mina: And we need your help

Momo: Since you’re a number 1 hero in another country

Monoma and Bakugo: and this team needs to be beaten

Eri and Kota: doesn’t know why they’re there
