It was that time of year. That one time of year that came a couple of months before Christmas. Halloween. Throughout UA, students and teachers alike were secretly planning whatever they would get up to that night and what costumes they would be wearing. Izuku Midoriya was one of them. Normally, he would dress up as All Might, but he was feeling like switching things up this year, now that his idol-turned-mentor had retired from hero business. Being a hero school, UA gave its students the option to attend their classes in costumes. It even allowed those within the heroics course to spend the entire day in their hero costume. This was a given as only 2% went in their uniform anyway.

That day, Midoriya had dressed himself up as the no.2 hero, Hawks. Although his trademark red shoes had given him away, his take on the Winged Hero was so identical that you could confuse him for the real Hawks. Hell, he had even dyed his hair blond. That's dedication. His choice of costume was just one of the eclectic and eccentric choices 1A had made.

'That is so rad!' Denki Kaminari exclaimed. 'I can't believe Hawks is right inside our classroom!'

'In the same way I can't believe I'm sitting next to Pikachu,' snarked Kyoka Jirou, who was surprisingly wearing Momo Yaoyorozu's hero costume.

'Not many top 10 heroes walk inside our…'

'Actually, they do. And they bring friends.'

'Midoriya, can you put your wings down?' asked Minoru Mineta, in full hero costume. 'I can't see squat out there.'

'Boy, you don't really take notice until a hot lady walks in,' said Hanta Sero, playfully.

'That's the point, Spiderman! What if some hot thing walks in the room, like now? I'll be missing all the goods with these wings blocking my view!'

'And what are the chances of that, Grape Juice?'

'You never know, man.'

During this conversation, Shota Aizawa walked in the room to greet his class. To say that he was impressed with his students' vivid choices was an understatement.

'Nice to see I'm not the only one who decided to go as themselves tonight,' he said in his typical, Eraserhead tone. 'But I can't exactly say I totally approve of my students swapping costumes with each other.'

'It's just a stylistic choice, Aizawa-sensei,' said Momo, dressed up as Earphone Jack, aka Jirou. 'I don't remember anyone objecting to costume swaps.'

'Can't argue with that, I suppose. Anyway, let's get started with the class.'

Lunch couldn't come sooner. Since this was their first Halloween as UA students, class 1A were dazzled by what they saw. It felt more like a pop culture convention rather than a school. When they got to the lunch hall, it truly looked like UA was hosting a pop culture convention. You had the whole gamut of cosplay; from prolific comic book superheroes to the most obscure anime characters, from the standard Halloween costumes to creative interpretations of literature characters. That was the marvel of Halloween. Who needed trick-or-treating when you had costumes?

'I've never been to a convention before, but this must be what it feels like!' said a beaming Ochako Uraraka, who was going as Mandalay. In the same way Midoriya had the Hawks look to a T (minus the shoes), she came close to looking a lot like Mandalay. She even had the cat gloves.

'You're correct, Uraraka,' said Tenya Iida, dressed up in his costume. 'This is what a convention is exactly like, speaking from experience.

'Have you been to a convention before, Iida?' asked Uraraka, curiously.

'Yes. Many times. I even went to the fabled events in America once.'

'Wow, so exciting!' said Midoriya, who lit up at the sound of America. 'Which one was it?'

'I believe it was somewhere called San Diego.'

Elsewhere, Katsuki Bakugou was just chilling, decked out in his costume, when Kaminari briefly glanced over. His eyes shot up at a specific picture.

'Did Camie really snap you that pic, Kacchan?' he asked.

'Why do you care, Pikachu?!' he retorted.

'I'm just saying that she looks hot like that, is all.'

'I know what you're thinking. I'd expect that shit from Grape Head, but not…'

'Hey everybody!' spouted Kaminari. 'Kacchan has a pic of his girl dressed up as Mirko!'

'For reals?' 'Can I see?' 'This is what makes my Halloween!' Before he knew it, a small crowd gathered around a face-palming Bakugou, wanting a brief glance of Camie's cosplay. Not even Midoriya and Iida could resist the temptation, to Uraraka's chagrin.

'Lousy pervs,' muttered Jirou. 'They see Mirko almost all the time, so why should…'

'Because Mirko cosplays are surprisingly rare,' interrupted Momo.

'Will we be saying the same about Creati cosplays in a few years to come? Seriously, I don't get how you don't feel uncomfortable running around like this.'

'Truth is, I do. Since it greatly benefits my quirk, I have to hide any discomfort I may feel. I wish I could wear your costume all the time, it feels so warm.'

'Aw, thank you, Momo,' said Jirou, with a slight blush and endearing tone to her voice. 'My costume is rather plain and normal-looking, so I don't get many compliments.'

'Speaking of cosplays, I need to see if Camie's was well-done. It makes or breaks a cosplay for me.' As she ran to the crowd, she yelled out, 'Bakugo! Don't press the home button yet!'

Briefly hesitiating, Jirou walked up as well, smirking at the thought of getting Kaminari to whey out. 'What a smart but flimsy excuse for Momo,' she thought.

While this was happening, some students from the other first-year hero class were watching the scene with varied reactions.

'All this over a Mirko cosplay?' asked a baffled Itsuka Kendo.

'She's buff,' said Tetsutetsu, nonchalantly. 'What d'ya expect?'

'Shut up, Jojo. Don't make me give you the hand.'

'Yare yare daze.'

'Good grief, indeed,' Ibara Shiozaki agreed. 'It is scenes like these that prove the world strays further from the light every day. It is becoming more of a struggle to keep my ideals.'

'Says the girl dressed up as Tatsumaki,' Neito Monoma remarked. 'Besides, who needs this travesty when we have her and Chun-Li right here?'

'I'll be honest, I actually thought of going as Kagura,' said Kendo. 'Problem is, my hair was too long to tie up into those little odango, let alone stuff inside the little hair decorations.'

'And you had no problem with Chun-Li at all?' asked Jurota Shishida, dressed up as the Beast.

'So what? I can go as Kagura anytime!'

'I think everyone's leaving Bakugou alone now,' said Tetsutetsu, just as Jirou was passing them by, dragging a maxed-out Kaminari as she went along.

'Hey guys,' she softly said.

Expect for Monoma, everyone waved at her.

'At least that is over,' said Shiozaki, starting to smile.

'Wait until Bakugou gets more pics of that cosplay,' snarked Kendo.

After that incident was over, lunch break went on as normal. Like nothing ever happened.
