The LOV Is Too Cool For School - Tumblr Posts
Who needs school? What they lack in general education, they make up for with...

Did anyone in the League even ever graduate high school????? We have like canon or near-canon evidence that literally almost all of them are pretty much middle-school dropouts.
Twice: Orphaned when he was in middle school, had to leave to start working
Toga: Had to go on the run after right after graduating middle school
Dabi: “Died” as a middle schooler, presumably did not continue going to school after surviving the forest fire
Spinner: Hikikomori; might have stopped going to school completely due to bullying
Shigaraki: hidden in underworld shadows since age 5; Never even set foot into a public school
And that leaves Mr. Compress, who is the best candidate to have actually finished his schooling; except I have a funny feeling he might have decided school was lame so he dropped out to become a homeless street magician.
