Tara's Note: Since there's maybe five of you who stuck with me on my Marvel to Buffy to Harry Potter to My Hero Academia journey, this is going to be a new concept to a lot of you. Long story short: the plot for this story originated on a site called Twisting the Hellmouth over twenty years ago. The main premise was enabling otherwise difficult to justify crossovers. I decided to pick up the entire idea and move it to a new fandom while keeping the core concept intact. So... let's go.


Chapter Text

As consciousness returned to him in a rush of dull aches and throbbing pains, Midoriya Izuku knew before he even opened his eyes that the last thing he wanted to do was… well, open his eyes. It was the same feeling that he'd had on the morning he first woke up to train with All Might, upon waking up for his first day at UA High, and when he woke up the day of his final battle against Shigaraki Tomura and All for One. It was an undefinable but now unmistakeable feeling that once he opened his eyes, nothing would ever be the same.

So instead of trying to face the outside world, Izuku kept his eyes firmly shut, trying - and generally failing - to ignore the throbbing in his head. Considering he was naked and in a bed? He really hoped that he'd made it back to his hotel room last night. And not... somewhere where being naked and asleep was a problem. It was definitely a bed, though, so chances were that he wasn't in jail? He couldn't hear Bakugou Katsuki's obnoxious snoring, though. Which meant he'd either slept in... or he wasn't in his hotel room.

To be honest, this was far from the weirdest situation that Izuku had ever been in. Especially compared to his tumultuous first year of high school. Villains weren't invading I-Island again. He wasn't on the run across Otheon as part of a quirkless supremacy conspiracy. There wasn't a flying ship-island-thing full of quirk enhanced mobsters bearing down on them. Waking up somewhere strange in Vegas was honestly... a refreshingly simple sort of problem in Izuku's life.

To be fair, his life after the fall of All for One had been comparatively simpler. Sure, a few different villains had tried to rise up to replace All for One after the war. But none of them had the power - or the sheer menace - to be a threat to society the way All for One had, and the pro heroes of Japan had risen to the occasion each time. And so Izuku had spent two years going to class, patrolling and handling simple villainy as an intern, and keeping the embers of One for All alive as best he could.

He’d actually managed to reach the podium in the second year sport’s festival, and beaten Katsuki to take the gold during their third year. He’d lived a little. Dated a little. Made a lot of precious memories. And then One for All had finally faded from his body, and Izuku had become just another citizen of Japan.

Well, just another citizen with a hero license and a few action figures of himself.

From there, Katsuki had gone solo as a hero and founded the Ground Zero Agency, while Izuku had gone to college to get his teaching credentials. He’d stayed close to his classmates. Closer to Katsuki. He’d graduated with honors, and prepared to enter the workforce.

Which led to the present. Katsuki had decided that Izuku had worked entirely too hard getting his bachelor's degree in quirk studies and teaching certificate, and had dragged Izuku halfway across the globe to 'unwind'. Since when Katsuki knew what 'relaxation' meant, Izuku had no idea. But Katsuki had gotten it in his head that Izuku needed a break from everything, and so... they ended up in Las Vegas, Nevada.

When they'd arrived at what was supposed to be their temporary home away from home, Izuku had been forced to keep Katsuki from exploding the woman at the front desk when she snootily informed them that 3:27 PM was in fact not close enough to their advertised 4:00 PM check in time to be acceptable, and they would have to wait another thirty-three minutes before she'd be able to process their reservation. Katsuki had discovered firsthand that his international fame was non-existent, and gone huffing back outside to think. Izuku had apologized profusely before following.

The pair had argued a bit at that point but as always, Izuku was the voice of reason. If they went back in and argued more, they might end up next to the ice machine or the elevator or something equally disruptive to their sleep. Katsuki evidently didn't plan on them sleeping terribly much... but had conceded the point. Which had left them struggling to figure out a way to burn half an hour in a way that didn't involve Katsuki glaring at the front desk attendant.

The solution to their problem had been obvious as soon as they'd walked out the door: exploration. While they were in one of the smaller hotels, there were numerous massive 'hotel and casino' complexes that were also home to shows to be seen, restaurants to try, shops to… shop in, a few roller coasters and other thrill rides for the braver folks… Izuku even vaguely remembered hearing something about one hotel having an aquarium with sharks, although he couldn't remember which for the life of him. All sorts of exciting things to see and do and that was before they even began ducking into the actual standalone buildings that housed stores and attractions of their own. So they'd grabbed their wallets and set off in search of fun or - at the very least - a way to kill half an hour.

From there? As best he could remember, there'd been some gambling, some showgirls, a lot of drinking, and now he was waking up… somewhere. Katsuki really was a horrible influence, Izuku decided. Since when did Katsuki know what alcohol was? Since when did he drink, for that matter? He had a throbbing headache and for some reason, most of his entire body ached? Especially his hips? What had he done that had impacted his hips like that?

Turning his head slightly to one side, Izuku cracked his eyes open and peered over at the alarm clock. 9:42. And considering there was sunlight filtering in through the closed curtains, Izuku was pretty sure it was 9:42 AM and not 9:42 PM. Given how far he had to look? He was pretty sure this wasn't the two double bed room that Katsuki had booked for them. Hopefully Katsuki had found his way back to it? Otherwise, that was going to have been a horrible waste of money that Katsuki wouldn't stop complaining about for days.

Suddenly, Izuku realized that he was not alone in the mystery bed. While his relationship with Asui Tsuyu hadn't gotten very far, they had slept together - literally slept - a few times and so Izuku wasn't entirely unfamiliar with the sensation of having another warm body in the bed with him. How he'd ended up in bed with someone in Vegas, presumably in their hotel room? He had no idea. But evidently he had.

That... possibly explained some of the other aches?

Blush.

Peering downward at the top of the woman's head, Izuku raised an eyebrow. He wasn't a great judge of age, but she definitely looked older than him. His type was older women? Interesting. No wonder him and Tsuyu hadn't worked out. She shifted in her sleep, throwing an arm across his body, and Izuku lifted the sheet to peek underneath. Yeah, she was naked. And wow. Long. Or rather, tall? Izuku was still only a solid one sixty-eight at twenty-one, and this woman was very... not. Wow. Go him. Then the impossible happened and someone grabbed him from the other side, making Izuku squeak softly. He'd slept with... two women? He'd had a threesome.

Oh, Mineta Minoru could never find out about this.

Izuku chanced a peek over at the other woman, who was equally tall, before letting his gaze rise to her face. She was also older than him, with black hair and a more tanned complexion than the other woman, with a slightly reddish undertone. She was... Izuku lifted the sheet again and peered back and forth. The woman on his left was muscular, maybe even more so than him. The woman on the right was a bit less built. They were both curvaceous enough to make Yaoyorozu Momo jealous, though. Damn. Who were these women? And how had he met them?

His eyes wandered around the room, wondering exactly where he was and how to get out of there. And he needed to find his clothes some time before he attempted to solve the latter question, obviously. Suddenly, his gaze landed on the dresser, where a golden horned headdress was leaning against a winged silver helmet. That made Izuku look down at his bedmates again. Even in the age of quirks, that was... a little weird to be wearing casually. Granted they could have been dressed up strangely for Vegas; lord knew he'd seen some odd stuff in his short time there. But... had he managed to have sex with two local heroines?

Trapped between the two decidedly lovely ladies... wait, was he? He was pretty strong still, even without One for All. Izuku tried to sit up and let out a squawk as the woman on the left exerted decidedly superior strength, forcing him back down onto the bed. Okay so either strongly quirked individuals or local heroines. Cool? But also... now what? He kinda needed to go to the bathroom. And he could use some water. Oh, and now that he was paying attention, someone was either in the bathroom or had left the shower running, because Izuku could hear water falling? He didn't necessarily want to escape; he wasn't the kind of guy to have sex with someone and leave before they woke up. But getting up would be... really nice, right about now.

Also, the water bill was technically the hotel’s problem but Izuku didn’t want to be impolite.

Okay. If brute force couldn’t solve the problem, what about his flexibility? Izuku shifted experimentally in his bedmate’s grip, and managed to squirm closer to the tanned ravenette. Mentally apologizing for if they were as much strangers to each other as they were to him, he grabbed the other woman and twisted his body, shoving her into the muscular woman’s arms. Izuku held his breath and then let out a sigh of relief as his former captor let out a soft huff and pulled her new companion closer, snuggling with her. Finally. He was free.

Izuku brought his hands up to crack his knuckles - his joints were a little wonky every time he woke up - and then paused. There was a ring on the ring finger of his left hand. And the middle finger. And the index finger. They were all the same: simple gold bands. But they were most definitely on his hand, and had not been the last time he saw it.

Oh.

Oh no.

No no no.

Not quite panicking but firmly on the verge of it, Izuku eyed the balcony visible through the sliding glass doors. He still wasn’t the type to, erm, do things and run. Especially the thing that he’d evidently done. More than once, it appeared? But Float would have made it awfully tempting if he still had One for All.

Looking a bit further down, Izuku blushed down. Oh, right. He had… that. And so he was completely naked at the moment. Where were his clothes? Izuku began checking the floor carefully. Whoever these women were, they were a bit messier than he preferred. Whether there were two women here or three as his collection of rings hinted at, there were far more than three sets of clothing scattered across the floor. His keen eyes found his ‘t-shirt’ t-shirt poking out of the mess, and then… wow, his jeans were the smallest in the room, weren’t they?

Tugging his pants and shirt on, Izuku began to look around in earnest. It wasn’t quite a suite, but it was far larger than his and Katsuki’s room. There were distinct areas: a kitchen that looked untouched, a living room with a working area, and then the bedroom. And a bathroom. Izuku wasn’t ready to stick his head in there yet. And so he padded toward the desk.

Oh. Someone had plugged in his phone to recharge. All of their phones, and there were in fact four of them. And two tablets, and a closed laptop. Izuku picked up his phone, tucked it into his pocket, and then hesitated. He slowly opened the laptop and was greeted with a background of three smiling women: the two women from the bed and a paler skinned ravenette woman who was evidently the owner of the golden horns that he’d noticed. Huh. At least he had good taste while drunk?

Izuku closed the laptop and pulled his phone back out. While he wasn’t going to leave until the situation was settled, he figured that he should probably at least check in with Katsuki. And so he opened up the Phone app, went into his Favorites, and called his best friend.

Or at least he tried to. After four rings, the call rolled to voicemail and Izuku ended the call. He debated calling again - it was well past when both of them usually woke up - but maybe Katsuki was occupied with something? Obviously not looking for Izuku or he would have answered the phone, but…if this was what Izuku was waking up to, who knew what kind of situation Katsuki had gotten into.

Frowning, Izuku switched to Find My, where the pair had shared locations with each other for, uh, strictly professional reasons. Not that Katsuki worried about Izuku now that he was quirkless again and Izuku had refused to share his location unless Katsuki reciprocated. Nope. Certainly not. But his friend’s dot was firmly located where it was supposed to be: the hotel that they’re booked a room at. So at least things were going according to plan for one of them.

His friends knew they were on vacation, so messages were sparse. Seven from Eri. Two and a picture of Eri from Uraraka Ochako. What looked like a veritable essay from Yaoyorozu Momo, undoubtedly lamenting the latest misadventure to befall her because of the fact that she was a morosexual. She was a fairly verbose texter, but only exasperation with her wife tended to bring out that sort of word count.

Oh, and a dozen images in a single message from Minoru. A message that Izuku closed before it could even finish loading. Why the young man thought Izuku wanted to be ‘quality control’ for his girlfriend’s OnlyFans content, the verdette had no idea but it definitely wasn’t what he needed at this precise moment in time.

It was then that Izuku realized someone had neatened up the desk, presumably that morning after waking up. There were three bouquets of pure white roses artfully arranged in a half-circle around a piece of paper. Which turned out to be three pieces of paper when Izuku tried to pick it up. Considering he had the rings and the women to prove it, the marriage certificates were more confirmation than anything else but… hoo boy. That literally made the whole thing official.

Izuku Midoriya and Loki Laufeyjardóttir.

Izuku Midoriya and Amora Incantare.

Izuku Midoriya and Jane Foster.

Oh jeez. Katsuki was going to have a field day with this…
