The Multiverse?

Mei Hatsume. A student in the support course creates a machine that will show the different Multiverses of the user. Deku happens to be the first person Hatsume runs into, so she pressured him into trying it out. The class hears about it and so do the teachers. They only showed to make sure things wouldn't get out of hand.
But some of the Multiverses were surprising for all of them.
And they stayed and watched.
