The time is 14 years after the current story.

Eijiro Kirishima, also known as Red Riot, is the number 7 hero.

You have a Diamond transformation-type Quirk that lets you turn your body into diamonds. You have always been a fan of Red Riot and always wanted to work with him. So much so that you even joined the hero school he graduated from, U.A. High. After the sports festival, you had to choose an agency to do your internship in. When you saw a request from Red Riot himself, you knew there was no other option.

You are now on your way to Hiroshima, where his agency is located.
