Chapter Text
Once a year, the International Hero Association selects a small number of schools to send on a regular field trip. Around 20 years ago, there was complaints all around of how some hero schools faced more stressful situations, how regular schools were still affected by villain attacks, how heroes enforced dangerous training missions while others were so called "slacking off." In order to please the protesters, they annually picked the top nine schools (which meant both hero and normal schools) who had the highest number of injuries for their students and staff. A whole system was invented to see if the injury was minor or major, and UA was bound to be picked as the first years had already underwent two major villain attacks with a kidnapping during the second one.
Que Bakugou flopping on the ground.
He didn't want to go waste his entire day on a shitty tourist attraction when he could instead be training. But the idiots practically dragged him out and forced him in the bus. He could've broken out of their hold, but he let them take him. He was sorta hopeful that he would see a certain someone anyways.
Since the IHA was international there were only three hero schools in Japan that were selected. UA, Shiketsu, and Aldera High. A school that's surprisingly not a hero school, Aldera High. Which was located in the most shadiest part of the city and were students bullied and fought each other on the regular. Bomb threats, shootings, jumping the person who tried to shoot up the school and beating them within an inch of their life was all very common. Heroes had tried to intervene before but the students were aggressive, broke, and had terrible home lives. They demanded that they didn't need help and protested heavily at the appearance of heroes. It was basically a harvesting ground for future villains and criminals. There reputation was low, and most students never made it out of the dump.
That's why, when the field trip had been planned and the schools were invited to a fancy five-star museum with expensive and rarely seen historical artifacts, most of the Aldera kids didn't even bother to show up. Only 5 came, and then 4 left when they saw UA's and Shiketsu's teachers who were heroes.
And since only one student from Aldera High was present, they were added to the UA group instead of isolating him. But Class 1A hardly noticed as they conversed with the first year classes from Shiketsu. They didn't see the delinquent teen head to the corner, where one fierce blonde stood. They didn't see them lock gazes, didn't see the Aldera kid stand next to the blonde as they smirked at each other. That's right, in the corner Bakugou motherfucking Katsuki and Kariage reunited for the first time in months.
.
Katsuki grinned as his best friend of 16 years, and lover of 3, stood next to him. He liked having Kariage around but he couldn't do any of the normal shit that he would've done. Such as pecking him on the cheek or jumping on his back for a piggyback ride. He pretended to look all angry and brooding but he was inwardly ecstatic at the sight of the familiar undercut. But he still had a bet going on with Dehisa, he couldn't afford to break character in front of his classmates who have come to see him as a serious, temperamental asshole.
The first time Kariage heard Katsuki's goal for his new class he had bursted out laughing his ass off, knowing that Katsuki was the same guy who started a Just Dance battle on top of the tables in the public library, and then brought a dozen chickens as an apology to the librarian. Who then placed a permanent ban on him. He has the most stupidest videos of Katsuki doing the dumbest shit imaginable. Then he added on to Dehisa's bet of 500 yen and bid his own 100 yen that he couldn't do it. So naturally, Katsuki went all out and is now 100 yen richer. He needs to make it to the middle of the year in order to get Dehisa's payment.
Bakugou and Kariage silently agreed to stay next to each other and just act casual, like they didn't know each other. It was a nice plan, they didn't have the pressure of Katsuki's classmates coming up and asking about his favorite idiot. He sighed, knowing that would mean the day was bound to be boring.
But all plans of peace flew out the window and fucking died a miserable pathetic death the moment Kariage and Katsuki spot that Mr. Ozawa, a teacher they had in middle school for two years in a row, would be one of their groups leaders. His face lights up, they grin like cats who just caught their prey while their eyes immediately lock onto each other.
He was wrong earlier, this day is going to be so fucking fun.

Class 1A was paired with one of Shiketsu's classes and Class 1B was paired with the other. Kariage went along with Katsuki's group as they toured the museum, Aizawa, Present Mic, Mr.Ozawa, and other teacher from Shiketsu as their guides. They would occasionally stop and point out some art pieces and statues and explain the history behind it.
Katsuki and Kariage stuck to the back of the group, not really paying attention as they subtlety played rock paper scissors. Katsuki sticks his tongue out at him as he wins the 6th time in a row. Kariage retaliated by shoulder checking him as the group moves forward. Katsuki hip bumps him the next time the group stops.
Aizawa is describing a painting, explaining its origins and the rest of the group is pin drop silent as he talks. He sounds tired, and his voice sorta reminds him of a college professor droning on about some lecture. Kariage, who is standing right next to him, taps his foot. One tap left foot, double tap left foot, one tap left foot. ("I love you")
Katsuki tries very hard to stop the blushing rising into his cheeks from both the embarrassment but also from how flustered he gets when Kariage tells him that in a public setting. Then he taps it back.
Mr. Ozawa speaks up, interrupting Aizawa's sentence and their cute little moment. "Bakugou. Kariage. Quit it."
He can hear how Kariage's head snaps up (no literally, the dude probably just cracked like 10 bones alone with how fast he looked up, what the fuck-?) to meet Ozawa's glare while the rest of the two classes turn to look at them curiously, completely unaware of the whole lovey dovey spiral going on behind them.
"We literally weren't even doing anything!" Kariage sounds offended, but they've been through this song and dance way too many times in middle school for either Bakugou or Ozawa to believe this bullshit.
You see, back in Aldera Middle School, Bakugou and Kariage were known as the Chaos Duo. Sometimes it was the Chaos Trio when Dehisa decided not to skip school and join in on their shenanigans.
There were two common ways they would mess around, the first being that they'd communicate in a mix of pencils hitting the desks, foot taps, "accidentally" dropping things, and a series of small hand gestures that looks like normal things any student would do. But, Kariage, Katsuki, and Dehisa were little shits who wanted to take everything up to the max. And how more to be annoying than to make up a secret language of such mundane actions?
Really, Mr. Ozawa hated them ever since he figured out that they had this little something going on. He hated they he knew that they were speaking to each other, but just couldn't find a way to prove it since he had absolutely no idea what they were actually saying.
He had tried to give them detention once but Kariage and Katsuki both fought it and brought it up to the principal. And as Katsuki was literally Aldera's star, he'd let him slide and bend the rules. He didn't like Kariage nearly as much but he didn't need much convincing from Katsuki to let Kariage get away with things that 99% of other students wouldn't (That other 1% being Katsuki himself.) So detentions weren't all that common for them.
But the few times Ozawa tried and the constant lectures still pissed him the fuck off, so he made it his mission to annoy the absolute hell out of him. Kariage and Katsuki would use their language insistently, making sure to flaunt it obviously in front of Ozawa but to keep it subtle enough that other students wouldn't notice. Making Ozawa seem crazy (and if a rumour spread of how Ozawa was apparently a schizophrenic, then it had nothing to do with the duo.)
There was never a point were Ozawa didn't care about it. He always called them out whenever he suspected them of using their secret language, turns out somethings really just don't change. Proven by the fact that he's glaring at them almost a year later.
The second way they liked to cause trouble in a way no one could really give them consequences for was to bust into classrooms and spit out the most made-up, random, ridiculous shit, and then have it be true.

Kariage busted into the music teachers class, sounding panicked and pointing at the ceiling with insane hand gestures. When the teacher asked what was wrong,clearly concerned about him, he took a couple deep breathes and claimed a raccoon was fighting a snake in the rafters. Which could've been believable, if he didn't add on that the raccoon was dressed in a Winnie The Pooh costume.
"How would you even know that?"
"It's true! I swear! Winnie's beating the snake real bad!"
"Kariage, respectfully I have an entire class to teach and I'm sure that a raccoon is not fighting a snake in my ceiling."
At that very moment, there is a loud clambering sound coming from above, and one of the ceiling tiles are being taken off and thrown onto the floor. Katsuki's head pops out and he takes a moment to scan the room. His eyes land on Kariage and he beckons him forward.
"Cmere, I got them."
When Kariage gets into range, he throws a very fat raccoon into his arms, making him let out a very inhumane sound thats a mix of terror and shock while it just lays in his arms like a lazy cat.
Then Katsuki himself drops out of the rafters and lands on two feet smoothly, holding a large white snake in his hands. Then holds it up so Kariage can see its face.
"Look at what that fat bitch did to her!"
A clean cut takes up her(? "Katsuki how the fuck can you tell a snakes gender?" "Not important, fuck off.") entire chin area. Kariage promptly looks down at the raccoons nails and three of them on the left hand are covered with blood, presumably the snakes.
At the sight of each other, the snake starts hissing at the raccoon, curling around Katsuki's wrist. The raccoon growls and puffs himself up, getting ready to pounce on her. Seeing this Katsuki pulls the snake away from the raccoon.
"Get your fat fuck under control!"
"First of all he is not mine! Second, HOW!?" Kariage shrieks when the raccoon jumps out of his arms in an attempt to attack the snake, which is being covered by Katsuki. The moment the raccoon makes contact with Katsuki, the snake also pounces out of Katsuki's arms.
They tangle together and the ugly sounds of scratching, biting, of whatever the fuck else they do erupt in the classroom as they move about. Several of the students scream, some jumping on top of their desks so their feet can avoid getting mixed into the crossfire. Some run out of the classroom, but there is only one who stays still. A student in the back of the class is sitting with his head down on his desk, clearly on his phone but trying to hide it. His feet are not lucky enough to escape from the two wild animals. Kariage and Katsuki just watch as the two fight themselves closer to him.
Eventually, they reach him and the snake accidentally bites his foot. The raccoon scratches his leg. The guy screams and stands ups, trying to run away. Kariage's hand shoots up to cover Katsuki's mouth because he starts cackling when he sees the snake climb the guys leg like a tree to try and hide from the raccoon. And in turn, the raccoon tries to climb him too.
At the end of the day, Katsuki ended up intervening and taking the snake off of him while Kariage took away the raccoon. They managed to avoid getting in trouble as the principal waved them off saying that they were helping the school by taking away the two dangerous creatures.
Kariage released the raccoon into the nearby forest that it had come from, Katsuki ended up liking the snake and convinced his parents to keep her. Which wasn't really hard as she was beautiful enough to make her parents adore her. She had nice white scales that had a translucent shine in the sun, and red eyes just like Mitsuki and Katsuki. Turned out she was an albino.

Katsuki gets dragged back into the present, Mr. Ozawa is glaring at them. Aizawa, Present Mic, and another teacher he didn't even bother learning the name off just seemed confused. Katsuki doesn't even want to look at the other students.
"Don't think I don't know what you two are doing."
Katsuki glares right back at him. "Oh really? Then what the fuck are we doing?"
"That thing!"
Both Kariage and Katsuki look at each other, then look at him, then look back at each other in sync, a confused look on both their faces as they shrug.
"What thing?" Kariage turns back to face him and Katsuki rolls his eyes at the teachers blatant accusation.
"Don't play dumb with me!" Ozawa snaps back.
"What did we do!" Kariage throws his hands out.
Katsuki turns to him. "No no, not 'we'. You're on your own." Then he turns to Ozawa, "What the fuck did I do!?"
Kariage shoots him an offended look but Katsuki refuses to look at him so boo-fucking-hoo.
"You know what you two are doing. So stop it. You guys are high schoolers, you should know better than this."
Katsuki huffs and Kariage rolls his eyes. Then Kariage turns to look at him weirdly.
"What?" Katsuki snaps.
"This is your fault."
"I'm going to shoot you with a gun."
Kariage doesn't even falter. "You wouldn't know how to aim it."
"I'm not stupid. Unlike you, Mr. Delinquent."
"I'd rather be a delinquent than a nerd that sleeps at 8pm every night."
"Call me nerd again and you'll see exactly how I got first place in the sports festival."
"With your anger issues?"
"That, and with my hands that can literally explode. You're talking to a walking bomb-threat."
"I'll just have All Might restrain you again."
Katsuki puts his finger up, "Okay one, Midnight and Cementoss restrained me. And two, All Might wouldn't spend his time on a useless piece of shit like you."
"You assume I'm useless because I don't have a strong quirk?" Kariage quirks an eyebrow up
"I assume you're useless because your sneakers are ugly ass knock offs of Nikes. You must be useless because your openly wearing them in public with no shame."
"Yknow what? Not everyone grew up rich. You wouldn't know that with your model mom and designer dad."
"No I do know that. I'm looking at living proof. Although I wouldn't call this living, more like barely surviving."
"Your hair looks like it's barely surviving."
"Doesn't change the fact that you tried to sell yourself on EBay for twenty bucks."
"I told you that in confidence!"
"You didn't tell me anything, I found out because I'm the one who had mercy and bought you."
"Oh yeahhhh, I remember now. Thanks for the twenty bucks by the way."
Katsuki snorts. "Thanks for your soul by the way."
Ozawa cuts in, interrupting whatever Kariage was about to say next. "Both you of, go wait out in the hallway."
Only then does Katsuki realize that literally the entire room just witnessed their conversation. He can sense Kirishima, Mina, Kaminari, and Sero stare at him. When he looks he sees that they're instead staring at Kariage, probably wondering why Katsuki hasn't exploded him yet. His gaze snaps to Deku, who is trying to hide his laughter. Uraraka and Iida pat him on the back when the nerd literally starts curling in on himself looking like a grape transitioning into a raisin.
He meets Mr.Ozawa's glare with one of his own. Their stand-off lasts for at least a minute before Katsuki backs off.
"Touché" He yawns before heading towards the door. Although he doesn't miss the weird way Kirishima was looking at him, and how confused the rest of his classmates were. Kariage follows him out with a shrug but still sticks his tongue out childishly at Ozawa, that earns him a smack on the head from Katsuki.
"Ow! What was that for!?"
"Your breath stinks so bad I can smell it from here."
"Hey!"
"Should've invested those twenty bucks into some goddamn toothpaste and a brush."
"At least I don't abuse my teeth every time I brush them."
"Nah, you abuse them with all that junk you eat."
Kariage tries to push him as they walk out they doorway but Katsuki gets to it first. He may have accidentally pushed him too hard as he flops to the floor and bonks his head on the doorframe. Katsuki snorts them omnisouly drags him by his feet. Kariage's body leaves the room bit by bit until it's fully out and the door shuts. Leaving the rooms occupants in shock, class 1a wondering why the hell Bakugou is being playful and who the fuck Kariage is.
Mr.Ozawa face palms. "Continue your explanation, I'll go deal with the duo."
