(8 years and 6 months later)
"Where's the fucking bride?!" Momo whisper-shouted behind closed doors as she and Kendo took turns trying to call the bride-to-be.
"I don't know! I've called her like seven times and she hasn't picked up once!" Kendo returned the whisper-shout. "You don't think she bailed, do you?"
"I like to think I know my daughter well! Young Katsumi is not a coward in the slightest." Yagi informed as he too waited for her to show up.
There was a loud screeching sound outside, and the three stared at the door that lead outside with baited breaths. They were let go in relief as a certain individual burst through the doors in a traditional, white wedding dress.
"Shit, how fucking late am I?!" Katsumi asked as she rushed in, lifting the dress up to make sure she didn't trip.
"Pretty damn late! Where were you?!" Momo asked as Kendo handed her a bouquet, and went to make sure nothing had affected the dress. Yagi stared with wide eyes, blown away by how beautiful his daughter looked. He wiped a tear that was beginning to form.
"Villain attack Rich Bitch, calm down! He'll understand." She grumbled the last part, trying to reassure herself more than them. She began to shoo away the redhead. "Get off of me! How do I look?"
"If it wasn't for the mask, you'd be perfect." Momo informed, while grabbing and removing the black eye mask Katsumi usually wore. "Hurry up, this thing should've started 10 minutes ago!"
"Are you ready, my dear?" Yagi asked as he and Katsumi entangled their arms. The blond closed her eyes and took a deep breath, before opening them again. She nodded.
"Show time." She said, before Momo and Kendo opened the doors for them.
They were met with rows upon rows filled with people from their lives, both personal and professional.
Nervous wasn't a feeling Katsumi felt often, but when she did, it was over something big. There was only a handful of times in her life where she felt nervous. Her first date with Deku after they officially got together, meeting her new father Toshinori Yagi, aka All Might, after he had adopted her (it still felt weird saying he was her father now, but hot damn did she love rubbing it in everyone's face), getting pulled off to the side by Round Face and being forced to promise to never hurt Deku, and the occasional interview Deku and her PR team roped her into. But this? This took the cake!
"You look very beautiful, Young Katsumi." Yagi whispered to her as they took their steps down the aisle, arms entangled as they moved, just like the weddings Katsumi watched on TV as a child.
Yes, this was indeed the wedding day of pro heroes Deku, ranked first, and Ground Zero, ranked third. But she was slowly climbing to take the spot of the second ranked pro hero, Icyhot.
It's been eight years since she and Deku had started to date, and what a wonderful eight years they were. Filled with everything she could dream of: love, laughter, warmth, safety, and sex…so much sex.
They managed to keep it a secret as best as they could from 1A, but sadly it was Katsumi who revealed the whole thing. How you may ask? Well it was during a training exercise during their third year of UA, where Shitty Hair and Deku were pitied against Icyhot and herself. The exercise was a two on two battle to either knock out or 'capture' the enemy team, much like their mock battles as first years with All Might.
Shitty Hair was easily captured by Icyhot with his ice, leaving Deku in a two vs. one situation. Katsumi got cocky knowing they had it in the bag, after all it was two powerhouses against one. What could've went wrong?
Everything. Everything went wrong.
Cause fucking Deku had failed to mention to her he had been practicing how much of One For All he could use, and the fucker never told her he was up to 60% by the time of their fight.
Deku floored Icyhot, twisting and turning to dodge the ice until Icyhot finally captured him in a glacier. You would think that was the end of it and that they would've won, but you'd be wrong. Because Deku, fucking Deku, flexed inside the ice and destroyed it. He was quick to KO her teammate, leaving the two lovebirds to fight each other.
The battle was long and they fought hard, but eventually, Deku had managed to capture her. He pinned her onto her stomach, hands tightly gripping her wrists above her head and as certain part of him grinded against her rear end.
"Stay down, or else." He whispered into her ear, hot and husky, causing her to shiver.
He and Shitty Hair were declared winners, and Deku had gotten off of her. Suddenly horny and pent up (after not doing anything for over two weeks), her emotions got the better of her and she kissed him then and there, revealing to all the truth about their secret relationship. Many questions were asked and even more death threats were sent (from her obviously) but overall (almost) everyone was happy for them.
They dated for eight solid years after that, and just six months ago did Deku finally pop the question. It was a small gathering, consisting of them, All Might, and Inko. It had came out of nowhere, but Katsumi was quick to accept. And then Inko cried…and then Deku…and then All Might.
And finally, here they were, surrounded by friends of 1A, 1B, some of the faculty of UA, and even a few of their sidekicks.
"You can thank Aunty for the dress, she's the one who picked it out." She whispered back to her…father (fuck, still weird to say and think).
"I shall once the ceremony is down." Yagi informed. "It's rather…strange being here. Not in my wildest imaginations did I ever think I would be walking my daughter down the aisle."
"Same here, but Deku's full of surprises." She said, causing the older man to laugh.
"That he is, that he is." He smiled, small and sweet.
They arrived at the alter where Deku, dressed sharp with slicked back green hair, and the priest, Present Mic (Katsumi was sure this was an alternate universe, it had to be) stood, smiling at them. Yagi patted her arm, before removing himself and sitting down next to Inko in one of the front seats.
Four Eyes, Icyhot, and Shitty Hair stood behind Deku as his groomsmen, while Racoon Eyes, Ears, and Ghosty stood behind her as Katsumi's bridesmaids.
"You look breathtaking." Izuku complimented, smile wide and bright, making her blush.
"You don't look half bad yourself. Can't wait to tear that off once we get home." She grinned mischievously at him, causing him to blush.
"Gross." They could hear Present Mic whisper, before he began. "Ladies and gentlemen, family and friends, we gather here today to celebrate the joining of Izuku Midoriya and Katsumi Yagi in marriage. With love and commitment, they have decided to live their lives together as husband and wife, something I'm sure none of us saw coming."
"You can say that again!" Kaminari shouted from the back, and received a slap to the back of his head via his date, Shinso.
"Oi, Insomniac, I told you to make sure your boyfriend behaved himself!" Katsumi yelled towards the purple haired male.
"You try making sure he behaves! It's damn near impossible!"
"Do you want me to come back there?!"
"May I continue?" Present Mic asked annoyed, causing Izuku to sigh.
"Yes please, I apologize for them."
"Don't apologize for me, Deku! Just because we're getting hitched doesn't mean I can't speak or apologize for myself!"
"As I was saying-" Present Mic a little louder, causing everyone to stop talking. "Izuku Midoriya, do you take this woman to be your-" Mic continued, which fell upon deaf ears.
"You know, you're pretty late." Izuku whispered to his bride. "A phone call would've been nice."
"A villain kidnapped some civies and was threatening to kill them, I figured you'd understand." She whispered back.
"I do, believe me I do. Just, try to remember to call next time, ok? I know I get overprotective, but it's just because I love you. You know that, right?"
"There's nothing to get worried about nerd, but-"
"And you, Katsumi Yagi?"
"Yeah, I do."
"If any of you has a reason why these two should not be married, speak now or forever hold your peace." Present Mic said, which was followed by 10 seconds of silence. No one noticed how a certain brunette's hand twitched. "With no objections, I pronounce this couple, husband and wife. You may now kiss the-" Present Mic was cut off as the blond launched herself towards the greenette, arms wrapping around him like a snake before their lips met, causing almost everyone to the building to cheer.
They stayed locked for a solid minute before finally pulling away, both grinning like wild animals before Izuku bent down and picked Katsumi up in his arms, carrying her bridal style as he raced down the aisle.
Laughs and cheers surrounded them as he ran, the two themselves laughed as well. But as Katsumi eyes the crowd of their friends, a certain frowning individual caught her eye, making her frown for a split second as well. Her stomach dropped at the feeling that was suddenly eating at her, but she was quick to shake it off.
That would be a problem she would deal with, later on.
(I know the wedding was weirdly chopped and whatever, but oh well, here it is. One chapter left to go before I start the next AU, so vote while you can! Also, if no one points out the reference in the beginning of the chapter, I'm disappointed.)
