The time is 14 years after the current story.

Momo Yaoyorozu aka Creati is the number 9 hero.

You are a student at U.A. High, and your school recently informed you that you need to pick an agency for your work study. Because the agency where you interned after the sports festival is very busy pursuing a dangerous villain, you had to choose from the 65 other invitations you received after the sports festival. While reviewing them, you found one you liked from the number 9 hero.

You go to "Creative agency" in the city of Yokohama and when you arrive you see many heroes and sidekicks.
