Midoriya Izuku is a notorious sweetheart. He never has a bad word to say about anyone. He smiles, he offers assistance, he uplifts. He’s nice, is what we’re getting at. Really, really nice. A fucking treasure.
So, when he interrupts a conversation about professional heroes to say, “Endeavor’s horrible,” it comes as something of a shock. It’s his equivalent of calling someone “a fucking shitbag asshole” (though not Bakugou’s, because he calls even his friends that).
This is the beginning of the end for Endeavor.
Over the course of three weeks, Class 1-A notes several things: Todoroki never speaks of his family, but does tense and frown when his father is mentioned. Midoriya and Bakugou both dislike Endeavor for reasons they won’t explain. Endeavor himself is, well, to be frank, kind of a jerk, as evidenced by his behavior in interviews.
Adding all these facts together, they conclude Endeavor is probably the scum of the earth.
(Todoroki doesn’t ever tell them anything, but he doesn’t need to. Heroes, even those in-training, are observant.)
A week after they come to this silent understanding, the second domino falls. The classroom is quiet, filled only with the sounds of pencils scratching, papers shuffling, and Aizawa’s soft snores. Todoroki finished his work twenty minutes ago, and is currently engrossed in Neko Atsume.
Kirishima puts his pencil down, turns to face Todoroki, and says as casual as a spring afternoon, “Bro, I really want to punch your dad.”
Not looking up from his phone, Todoroki gives a distracted, “Cool.”
“Just wanted you to know that. Kaminari, Jirou, and I are gonna figure it out.” Kaminari looks excited, but Jirou looks kind of exasperated at being implicated in the scheme.
Todoroki shrugs. “I’ll be your alibi.”
“Nice! If anyone asks, we were working on homework together, at the park.”
Iida is practically vibrating as he breaks in, “This sounds incredibly dishonest and furthermore against the rules! However! Endeavor does not conduct himself as a hero ought. I, certainly, have not heard anything you have just said. As you are all my classmates and I trust and respect you, I will trust you are wherever you say you are.”
Jirou rolls her eyes. “That’s…thanks, Iida.”
Regardless of this blatant, loud plotting, a plan forms and somehow goes off without a hitch.
Afterwards, no one will quite be able to say what happened. All they know is Kirishima dyed his hair black, took off for the weekend with Jirou and Kaminari, and reappeared late Sunday night with a shiteating grin. Endeavor appears in the news on Monday sporting a mysterious shiner over his right eye, which he refuses to comment on. Some people, possibly reporters, swing around to ask pointed questions.
(What happens is this:
Jirou secures a ride to Endeavor’s neighborhood, and drums the steering wheel while Kaminari and Kirishima carry out the rest of the plan. Kirishima poses as a huge fan of Endeavor’s and knocks on the door to, ostensibly, ask for an autograph. Kaminari zaps Endeavor as soon as the door opens, for once doing just the right amount.
Kirishima rears back and takes a swing. Then another, just for good measure. He stops short of spitting in Endeavor's face, though. Leaving DNA evidence behind is just amateur, no matter how satisfying it might be in the moment.
Then they run.
Jirou chews them out all the way back to UA. Still, even she admits the plan somehow came together perfectly. She’s not entirely sure how. Kaminari suggest maybe the universe itself wanted Endeavor to get punched in the face, and Jirou shrugs.
“You know what, I wouldn’t be surprised. The guy’s a dick.”
[They get away with it because Endeavor can’t actually bring himself to press charges against a couple of teenagers. It’s too embarrassing. He's also, honestly, too dazed to remember what exactly happened or who was involved, not that he'd ever tell anyone that either. He likes to think he has a reputation to uphold.])
Todoroki says, “What? No, I’m sorry, but your source must be incorrect. They were with me this weekend. Studying. In the park.”
“All weekend?” A skeptical eyebrow lifts. Todoroki lifts one right back.
“Yes.” Todoroki’s unimpressed glare could freeze water if he were so inclined. The probably reporters make themselves scarce. (As they leave, Iida shouts: “How dare you make such spurious implicated against my classmates! Of course they were in the park!! They told me so themselves!!!” while waving his phone. He looks so proud of himself for contributing, Jirou just pats him on the shoulder and mutters a flat thanks.)
Sero tapes a picture of Endeavor’s bruised face to the wall in the common area.
