Work Text:
Katsuki Bakugo, future pro hero, was currently enduring another boring school day in good ol' Mr. Aizawa class. His teacher was giving a lesson about the different body systems, which always bored the ever livin' hell out of him. Of course, Katsuki never took notes. He was an auditory learner and had a sharp ass memory, so he simply sat in seat and played with his favorite mechanical pencil. That is, until he felt a certain green haired nerd sitting behind him stab him in the back with a folded up piece of paper, which he quietly took without looking when Mr. Aizawa turned his back to write definitions on the board.
He opened it up the paper, which revealed a nicely drawn map of certain neighborhood streets in town with a little note on the back that read, "This good?"
Katsuki smirked and wrote under the message, "Fuckin' fantastic." and passed it back to Izuku. A few seconds passed before Deku rehanded him the note, which said, "Did Auntie Mitsuki finish the costumes?"
Before Katsuki responded, he looked up to make sure the close was clear. Yep, Aizawa was still on that board, still writing definitions. He wrote, "No shit, nerd. Imma go home and pick em up today," and passed it back before Aizawa could spot them.
Izuku passed the note back again, which said, "K, I'll come with u."
Katsuki looked up once again, only to see a black shirt and a hand in front of his face. He looked up higher at the face of a very annoyed Mr. Aizawa.
"Bakugo, Midoriya, I don't care how boring this is to you. That doesn't mean you can pass notes in class. Give it here and if you use your quirk to burn it, detention for both of you."
Rolling his eyes, Katsuki placed the note in his teacher's hand. Aizawa opened it up to read it to himself and then put it in his pocket. "I get it, it's Halloween, you two can talk about Trick or Treating plans, after class."
The whole class began to snicker at Aizawa's remark, Izuku put his head down in embarrassment, but Katsuki just sat there, unamused. Aizawa was right though, today was Halloween, Katsuki's favorite holiday. Every year Katsuki went Trick or Treating with Deku, yes, TRICK OR TREATING. So fucking what if he was 16 years old, getting free candy for wearing cool ass costumes is the shit. Plus, Deku always knew the perfect route for best houses.
Besides, in reality, this was the reaction Katsuki hoped for, Trick or Treating was his and Deku's thing. By the time Katsuki and Izuku hit sixth grade, no one ever wanted to go Trick or Treating anymore due to feeling "too old" for it. So it would always end up just the two of them, walking the streets together, getting candy and Katsuki got to see Deku's stupid smiling face and hear his dumb cute laughter and-God, he couldn't wait for this class to be over.
---
Just like that, the final bell rang. Aizawa closed up his book and said in the most uninterested tone, "Have a happy Halloween, be safe and all that. Midoriya, the note is on the podium. Pretty sure you need that." Then walked out the classroom without looking back. Izuku grabbed the note from said podium and walked his way back to his desk to pack up all his things. As the class dispersed, Kirishima walked over to Katsuki, who was still in his seat waiting for Izuku to hurry up.
"Hey Baku-bro, are you seriously going Trick or Treating tonight?"
Katsuki always knew how this went. Anytime he was questioned about his Halloween plans, it always panned out the same way in a 5 step process.
Step One: Loser questions Katsuki about going Trick or Treating
"Yeah? Is there a fucking problem with it?"
"Nothing, man. Just haven't done that since I was like 10."
Step Two: Loser mentions the last time they went Trick or Treating for some reason.
"Good for you. Is there a reason you're bothering me?"
"Well Mina is having a Halloween party at the dorms. You wanna go?"
Step Three: Loser suggests going to another Halloween event, despite being already told, Katsuki was going Trick or Treating.
"Why would I go to some lame ass costume party to just sitting around and do fucking nothing, Shitty Hair?"
"Huh, that's interesting, so you're really serious about it."
Step Four: Loser is confused that Katsuki would deny going to a party.
"Cool bro. I'll come with you then!"
Step Five: Loser leave them-what!?
Katsuki's eyes widened, wait no, that is not how the 5 step process is supposed to go, it literally worked 100% of the time. He looked over to Deku, whose eyes were just as wide when he heard those words, "R-Really, Kirishima?!"
Kirishima gave a huge shit-eating smile, "I mean, yeah. Like I said I haven't done it in a while, so it would be fun with new friends. I can come, right, Midoriya?"
Say no, Say, no, Say no, Say, no, Say no, Say, no, Say no, Say no, say-
"Of course, Kirishima! The more the merrier."
FUCKING HELL!
Kirishima turned around and raised his voice to any remaining people in the classroom, "Anybody else wanna Trick or Treat with me, Bakugo and Midoriya?"
Ochaco, Todoroki, Kaminari and even Tenya made their way over to Katsuki and Izuku's desks.
Ochaco jumped up and down, "Yeah! I'd love to go! I just got my costume shipped in. It'll be like when I was a first grader all over again."
Kaminari pointed a thumb to his chest, "Not to brag, but I was the Trick or Treat Master back in my day."
Tenya began chopping his arm in the air per usual, "A break from all this classwork can be a great bonding experience. I'll come with you Midoriya, but I don't want to stay out too late."
Todoroki blankly stated, "I never went Trick or Treating."
The whole group gasped in surprise to the half and half hero in training.
Kaminari and Kirishima hugged the very confused teenager on either sides of him while fake crying in unison, "You poor, poor soul."
Midoriya laughed, "That's great. We have a whole group. Kacchan and I usually start at 6, so we'll all meet up in front of the dormitory and head out from there. I have a map of all the best places to get the most candy."
Tenya looked at the phone for the time, "Perfect. It's 3:30, so that's more than enough time to get ready. Very good, Midoriya."
Katsuki glared at the group, "You fuckers better have your 'A' game because I will leave your ass if you're walking too fucking slow. Let's go, Deku." He jumped put of his seat in a huff and slung his bag over his shoulder.
Kaminari raised an eyebrow, "Where are you two going?"
"None of your fucking business, you underleveled Pikachu!" He barked.
Izuku answered the underleveled Pikachu's question, "Kacchan's mom made our costumes and they're at his house. So I'm going with him to pick 'em up."
"You talk way too fucking much, Shitty Deku."
----
The walk to the bus stop would have been very quiet if it wasn't for Deku's muttering. He was too busy scribbling down last-minute alterations to the map. For once, Katsuki let him do his creepy muttering because, Jesus, was he fucking pissed. It was supposed to be perfect, it was one damn time in the year where he finally got to be away from his idiot classmates and spend some time with Deku one on one on Halloween, but no, Katsuki never gets what he fucking wants.
Once they made it to the bus stop, Katsuki plopped himself on the bench and pulled a still muttering Deku down by his jacket to sit next to him, so the teen would stop walking. He should've tripped him. The schedule on the bus stop sign said the bus wouldn't come for a half an hour, so they better get comfortable. Katsuki wasn't going to endure this boy's muttering any longer, so he chopped Izuku on the head.
"Hey motor mouth, shut up."
"Ah! Kacchan! You didn't need to hit me!" Izuku whined, rubbing his head. He looked at his surroundings and turned to Katsuki, "When did we get to the bus stop?"
Why did Katsuki have to fall for this green haired idiot of all people?
"Stupid Deku, like fucking five minutes ago. You were too busy making out with the damn paper to pay attention."
Izuku blushed as he spoke, "I wasn't making out with the paper, Kacchan. I had to make sure the map had the best route for maximum candy coverage."
"Mmhm, whatever."
There was a long moment of silence, while they waited for the bus. Katsuki was playing a running game app with a playable red plumber character on his phone and Izuku was watching his favorite videos on All Might on his phone.
Izuku broke the silence after he finished watching all his videos, "Aren't you excited, Kacchan. We finally get to Trick or Treat as a group."
Katsuki didn't break focus from his game, "Hey, idiot, we technically were already a group before. Group literally means more than one."
"You know what I mean! It was always just me and you."
"What was wrong with that?"
"Nothing, nothing. I'm just saying, it's a nice change, that's all."
"Tch. So what? You want them to start coming every year now when we go Trick or Treating?" Katsuki said, still wasn't making eye contact and gripped his phone tighter than usual.
"I-I didn't say that."
Katsuki glanced over to Deku. That motherfucking fucker was blushing! What for? There's literally nothing to be blushing about. Then he felt his own cheeks burn. Emotions are pieces of shit.
As if on cue, the bus came to a screeching halt in front of them. Katsuki nearly jumped off the bench and got on that bus like his life depended on it. Izuku followed him at a much slower pace. The duo stood on the extremely crowded bus home to Katsuki's house.
They got off to the stop closest to the Bakugo household and made a quick walk there. Once they made it to their destination, the explosive hero opened the front door to see his mother in front of two mannequins, putting the finishing touches on Katsuki's costume. Izuku was going to be dressed up as a ghost and Katsuki was going to be dressed up as a werewolf.
"Hey brat! Hiya, Izuku! You kids ready for Halloween?"
"Hi Auntie Mitsuki! Yeah and My costume looks great! Yours looks amazing too, Kacchan."
"I know. I'm the one that came up with it." The blonde boy said with a smirk.
Mitsuki rolled her eyes, "Oh brother. If it wasn't for me you wouldn't even be able to have all the stupid amazing homemade costumes you wore over the years."
"Tch. Whatever old hag!"
"Don't you talk to me like that! Now get your ass over here. I gotta make sure this fits right."
Katsuki grumbled as he stomped his way over to his mother for her to fit him in his outfit. "Izuku, your costume is done. You can go upstairs and change in my room."
"Ok. Thank you." Izuku eagerly took his spoopy ghost outfit and made his way upstairs. Once she heard the door shut, Mitsuki gave a devilish smile, "So when's the wedding?"
"SHUT THE FUCK UP, MOM!" Katsuki turned bright red with pure embarrassment, which only made Mitsuki laugh harder.
After a few minutes, the boys had their completed costumes on. Izuku made his way back down from upstairs to show off his completed costume."Boo!" He yelled showing off the fake sharp teeth in his mouth. Katsuki felt his cheeks burn as he saw Deku. The green idiot looked goddamn adorable in his stupid, unscary costume. Masaru walked in the living room with an orange All Might themed pumpkin basket for Izuku and a black pillow case for Katsuki to hold all the candy they could carry.
"Hope you boys have fun." Mr. Bakugo said with a smile.
Mrs. Bakugo had a large bowl of candy in her hands raising a bit to the duo, "Imma give you boys a good headstart."
Katsuki loudly whispered to Izuku, "Don't take it from the witch, it's poisoned."
Mitsuki obviously heard that and yelled, "FUCK OFF, BRAT!"
--
Katsuki and Izuku stayed in the Bakugo household until it was 6 and Mr. Bakugo drove them back to the dormitory. There they met with the group, who were standing in front of the building, all dressed up for Halloween. Ochaco was dressed in her witch costume she mentioned earlier, Tenya was dressed as Frankenstein's monster, Kaminari was dressed as a devil, Kirishima was dressed as Little Red Riding Hood and Todoroki was dressed as a vampire.
"Oooh! Guys! All your costumes are amazing!" Izuku yelled.
"Thanks Midoriya, means alot coming from you." Ochaco smiled.
Kaminari noticed the candy in Katsuki's and Izuku's bags, "Hey! I thought we were doing this together! You two already got a headstart?!"
Katsuki irritatedly exhaled, "No dipshit, my mom gave us some candy before we left."
"Doesn't change the fact you got a headstart." The sparky hero pouted.
Todoroki walked up to Midoriya holding up a matching All Might pumpkin basket, "I like your style."
"Great minds think alike."
Katsuki growled, "Okay fuckos. Are we just going to stand around admiring stupid baskets or are we going to get some fuckin' candy!" Jesus, he hated seeing Deku talk to fucking IcyHot, made his blood boil.
Kaminari yelled, "Hell yeah, candy here we come!"
Tenya walked up to Izuku and Todoroki, "Lead the way, Midoriya. You have the map, yes?"
The green haired hero pulled out his homemade map from his pumpkin, raising it high in the night sky. "Trick or Treating starts now!"
The whole crowd cheered, except for Katsuki. He was in such a good mood at home until he remembered these fuckin losers were coming with them. Midoriya was in the lead with Todoroki next to him and fucking talking to him. Round Face, Pikachu and Glasses were right behind them and because of fucking course, Shitty Hair was walking next to him.
"You like my costume, bro? It was Kaminari's idea. Since red is my favorite color and all."
"You look like you just took a blood bath."
"Ha! You're just jealous, I'm pulling this off better than you ever would."
"Says the dude with the shittiest hairstyle I've ever seen."
Midoriya turned to the group, "The first house is coming up, so get ready, guys."
The first house was covered with Halloween decorations, always a good sign. Overly decorated houses meant really good candy. Izuku walked up to the front door and knocked, a middle-aged man opened the door with a bag full of king sized bars. Bingo.
"TRICK OR TREAT!" The group yelled holding up their baskets.
"Cool costumes, kids. Make a nice line, make a line." The man said dropping the king-sized candy bars in their bags. Each of them saying thank you when they got their treat. Then made their way to the next house.
Ochaco pulled the king sized bar in shock from her cat themed basket, "Whoa. I barely got these as a kid. They were always so expensive."
The second house door that Izuku knocked on was opened by a young woman dressed as a zombie held a bowl full of suckers. "Happy Halloween, you candy moochers!"
"TRICK OR TREAT!"
The woman smiled, "Just take a hand full." She lowered the bowl for them to grab their share. They each said thank you and headed for the next house.
"Are you having fun, Todoroki?" Izuku asked swinging his basket in unison his hot and cold friend.
"Yeah. I'm glad I got to come with you, Midoriya. I never knew Trick or Treating was this entertaining. My father always said it was a pointless tradition that wastes money."
"That's depressing."
"Wait, now that I think about it. He said that about every holiday."
"Good god, Todoroki."
Meanwhile, Katsuki was seething seeing Deku talking and laughing with that IcyHot bastard. He gritted his teeth and felt his hands warming up with anger.
"Baku-bro, you okay?"
"Fuckin' peachy, Shitty Hair."
The third house was small and no lights were on. One the porch of the house was a large black cauldron filled with all sorts of fun-sized fruity candies, sour candies and chocolates. There was a 'please take one' sign in front of the the cauldron.
Izuku turned his head to call to Katsuki, "Kacchan, can you help me with this?"
Tenya raised an eyebrow in confusion, "What do you need help for, Midoriya? It clearly says take one." He said as he took one, like the sign said.
Izuku ignored him as Katsuki walked next to the cauldron Katsuki lifted it and poured a large amount of candy into Izuku's basket. Then Izuku did the same to Katsuki's bag.
"MIDORIYA! WHAT DO YOU THINK YOUR DOING?!" Tenya yelled chopping the air with his arm.
Now it was Izuku's turn to raise an eyebrow in confusion at Tenya, while he was still pouring candy into Katsuki's bag, "What's wrong?"
"EH?! WHAT'S WRONG? THE SIGN SAYS TAKE ONE AND HERE YOU ARE TAKING-"
"Yo! Midoriya pour some in my bag!" Kaminari said pushing Tenya aside.
"Yeah, me too! Like your style Midoriya, so manly." Kirishima said.
Ochaco already had her basket readying for her turn at the candy waterfall, "Honestly, who listens to these signs."
Tenya stood in shock, "I can't believe you guys are doing this. These people bought this candy for everyone. Not for a bunch of greedy teenagers."
Katsuki rolled his eyes, "Tch, will you calm down, Glasses. God you and your stupid moral code is annoying as hell."
Tenya crossed his arms, "I won't take any more because I'm an honest man."
Izuku poured plenty of candy into their bags, then turned to Todoroki, "You want some Todoroki?"
"Is it really okay to just take it?"
"I mean, Kacchan and I do this all the time. You don't have to, if you don't want any."
Todoroki immediately opened his bag, "I just wanted to make sure it was okay."
"It's not okay!" Tenya yelled.
Izuku poured the remaining candy into Todoroki's bag. The cauldron was completely empty, just like Tenya's respect for his friends.
"On to the next house!" The group yelled, except for Tenya.
Then fourth house already had some trick or treaters at the door, a group of boys looked to be about 8 or 9. Once they got their candy, one of the boys walked passed the older group and one boy asked, "Aren't y'all too old to be trick or treating?"
Katsuki glared at the boy as he snarled, "Aren't you too young to be in other people's business?!"
The boy jolted a bit at Katsuki's scream and decided to walk a bit faster to catch up to his friends.
Kirishima shook his head, "Not manly bro."
"Shut the fuck up."
Izuku knocked on the door and it was opened by an old couple.
"TRICK OR TREAT!"
The old woman smiled, "Well look what we have here. So many great costumes. Here you go, babies."
She handed each of them a large goodie bag filled with chocolate candies and a bag with a fudge brownie inside. They said their 'thank yous' and off to the next house they went.
Kaminari had already opened the goodie bag and bit into the brownie, "Damn, that's good."
Tenya turned to Kaminari, "Kaminari we really shouldn't be eating anything until we get home and inspect it ourselves."
Kaminari was going to take another bite, but decided to put the brownie back in the bag, "Oh, c'mon, dude. No one poisons things anymore. That's so 2010."
"It doesn't matter, you can never be too cautious."
Katsuki growled, "Glasses, eat some fucking Benadryl and chill the fuck out."
"I can't chill out now, Bakugo, especially with that stunt you and Midoriya pulled earlier."
Izuku starting walking backwards to talk to Tenya, "Iida, people take more than one from those all the time."
"But the sign said, take one. And no one except me, followed the rule."
Katsuki popped a piece of cinnamon gum from his candy bag in his mouth, "You want a fucking cookie, Glasses."
---
The rest of the night went extremely smooth. Within 5 hours, the gang went through 7 neighborhoods and had loads of candy. They also raided quite a few 'please take one' bowls, much to Tenya's displeasure. To top it all off, Katsuki was getting more and more annoyed with Half-n-Half. He was pretty proud of himself for keeping his cool and not ruin Halloween for Deku, but he didn't really get to spend anytime with him like he wanted. The entire time Deku was in the front, while Katsuki's ear was talked off by Shitty Hair.
The group made it back to the dorms at around midnight. They saw Mr. Aizawa outside, sitting on the steps waiting for them. His hair in a bun and looking very, very tired. He had his hands behind his back for some reason.
The group stood in front of their teacher with huge, proud smiles on their faces. "Good evening, Mr. Aizawa."
The tired instructor pulled out his own black pumpkin basket from behind his back, "There's a Halloween toll, 10 pieces each or no entry. Considering you all have enough candy to feed a small village, I'm pretty sure I'm not asking for much."
"What's gonna happen if we don't pay the fee?" Kaminari bravely asked.
"You get detention for breaking curfew." Aizawa said bluntly with a wide smirk on his face. "Now, trick or treat."
The kids each paid his "fee" and went into the building.
Tenya yawned, "I am going to bed. Good night, everyone."
"I'm with you on that. I've never had this much candy in my Trick or Treating career. Next year, I'm definitely coming with you, Deku." Ochaco smiled.
"Yeah, man. Midoriya's the best." Kirishima said, patting the now blushing green hero.
"Aw, guys. It's just years of experience. That's all."
Kirishima, Tenya, Ochaco, and Kaminari all went to their dorm rooms, leaving Todoroki, Katsuki and Izuku in the living room. The three of them were on on the couches. Todoroki and Izuku were sitting on one, while Katsuki on the other, looking mildly peeved.
"Midoriya, thanks for letting me come with you, Trick or Treating, I really appreciate it."
"Aw, it's nothing, Todoroki, really. Now you know why Kacchan and I go every year."
Todoroki pondered for a moment, "But I thought you didn't like sweets, Bakugo. I figured Halloween would just be another day for you."
Katsuki glared, "Is there a problem with that, IcyHot? Last time I checked there was more than one type of candy."
"Halloween is Kacchan's favorite holiday, actually." Izuku said.
Todoroki turned his head in confusion like a damn child, "Really?"
"Yeah, fucking, really!" Katsuki hissed. This half-n-half bastard was seriously testing his patience.
"No need to get so hostile, Bakugo. I just find it a bit weird that you of all people would like this kind of holiday." Katsuki could've swore he say that motherfucker crack a smile. He was trying to play him. Not today, Shitface.
Todoroki turned to Izuku and gave him a hug, "Thanks again, Midoriya. I'm going to bed now."
Izuku hugged him back (he loved hugs) and smiled, "Okay. Good night, Todoroki."
Before he walked away, he said, "Good night, Bakugo."
"Hope, bed bugs bite you." He spat.
Todoroki shrugged his shoulders and disappeared behind the hallway, leaving Izuku and Katsuki on the couches. Izuku moved over to Katsuki's side and dumped all his candy into a pile on his side of the table. "You wanna trade, stuff?"
"Why'd you wait till now to do it, IcyHot was right there."
Izuku rubbed the back of his neck, averting his eyes, "You know this is my favorite part of Halloween," he paused for second, "and I like doing it with just you." Izuku's cheeks turned bright pink after that statement.
Katsuki rolled his eyes, feeling those stupid cheeks of his burn up, "Tch. Whatever, nerd. Gimme all the cinnamon-flavored shit."
Izuku smiled that goddamn smile, "Only if you give me all of your peppermints."
Katsuki dumped his candy on the table and started picking through his pile to find the peppermints. Okay, so maybe he did get what he wanted. It took fucking forever, but Deku was with him, one on one, trading Halloween candy. The green idiot was smiling and giggling, just like Katsuki hoped for.
Unbeknownst to the duo, Todoroki was hiding behind the wall of the hallway, shaking his head and sucking on a sour apple sucker, he whispered to himself,
"Those two are so obvious it hurts."
