Present Mic is the teacher who gives out stickers as a reward when students do good in his class
They're all in english, because that's what he teaches
They're not normal 'good job' 'way to go!' stickers, they're like. flavor stickers and shipping warnings.
The kids love them.
He doesn't allow them to stick them to anything it'd be a pain to remove them from (school property), but sticking them on each other is fair game, as long as it doesn't disrupt class
Some students Kaminari are sticking them to the wall in their dorms anyway, and will someday realize that is still school property and freak out about it
In every single class he's taught, it's inevitably led to battles of seeing who can put the most stickers on someone else without them noticing
1A's favorite victim is Bakugo, because if he catches them, he flips out and his punishment for disrupting class is not getting his own stickers, so he can't retaliate in kind. But if he doesn't catch them, he ends up covered in stickers for 'extra spicy' or 'caution: combustible' or 'live animal' or whatever the most ridiculous fruit flavor is
This also leads to various debates about the validity of various fruits???
Kirishima always wins the "stick things on Bakugo" game. Midoriya always loses. Even if he's not playing. Especially if he's not playing.
Their second favorite victim is putting Orange stickers on Iida's water bottle when he's not looking
In all the years Mic's been doing this, Sato is the only one who doesn't play, because he actually plans and saves his flavor stickers based on what treats he's planning on baking so he can label them before giving them away
If he can't get as many as he needs, the other students will team up to get him whatever other stickers he needs
Mic would actually give him whatever extra stickers he needs himself if he asked, but he doesn't offer because he likes seeing his students band together
Giving out flavor stickers also leads to stupid debates on what flavor would best fit each person
The fastest Mic has ever seen an entire class come to a consensus was 1A with Mineta, who tried to say he would be something cool, only to immediately be labeled Raisin. For obvious reasons.
Any time somebody has some dumb accident during training, the next day they'll be plastered in 'Fragile: Handle with Care' stickers
Sometimes he'll get *Special* stickers, and that's how you find out who everybody's favorite people are
One time Mic got a roll of 'This is a Set: Do Not Separate' stickers, and Midnight immediately stole them to randomly stick on him and Aizawa
Mic has also been known to make deals with his students that if they do well on tests, they can get extra stickers
Kirishima once makes a deal that if he aces his exam, he can get a whole roll of stickers, forces Bakugo to help him study again, wins a roll of Apple flavor stickers and gifts them to Eri
Eri has now joined The Game
She doesn't actually quite understand it and just sticks them to things she likes
This includes, but is not limited to: Actual apples. Various plushies. Every music system she has access to. Sushi the Cat and Vlad's dog. Midoriya, Mirio, and Aizawa.
Somehow this chain of events leads to Mic needing to carry extra rolls of stickers at all times so he can reward students for doing good things outside of class too
