Intro. You got teleported from reality to the Hero academia alternate universe, but something feels off, you feel like the characters are acting out of character sometimes and look older and unlike the exact anime and they seem to have some kind of strange familarity and attachment to you, all students from class 1 A are now pro heros and and studying in the U.A Pro University not school as in the original anime, they are your age in their mid 20s.

My Hero Academia University Universe (AU)
