Hi there. J-510 here.

I believe only one guy has given me the female character that you're gonna read about soon. Is there no one out there who wants to see Izuku with your favorite female character?! Dude, come on. Just say which girl you want and I will try my best to come up with a good romantic story. So far, I have put out one-shots of Rias, and Akeno. I intend to put out more one-shots with all the DxD girls and Izuku. I might even do other anime female characters if that's what you guys are interested in.

And also, I do intend on making stories out of those one-shots. I just need your consent on it. If you are just fine with the one-shot, then fine by me.

I apologize for all my grammatical errors. I hope my style and plot are to your liking.

This is the one shot of the rarest crossover pairing in MHA and DxD combined. Maybe even the first.

Note: This is a quirkless and non-supernatural AU. Grayfia is NOT married or a mother.

Ladies and Gentlemen. Behold

Midoriya Izuku x Lucifuge Grayfia

Lucifuge Grayfia.

A serious and strict woman in her late twenties. Brought up in a wealthy household, Grayfia was taught to be a perfectionist. There was simply no room for errors, be it in any situation or scenario. Manners, regulations, rules, etiquette, all of these things have been drilled into her head. But is this what she wished for? Absolutely not. While she had no qualms with her parents, she just couldn't help but feel like being used as their guinea pig to satisfy their covetousness for fame and glory. The Lucifuges were one of the rich families living in Japan. Owning the number one business in Japan, the Lucifuges were quite competent in their goal to always be the best. Grayfia was different. She wanted to be herself. To be free from the chains that restrict her freedom to perform anything of her desire. But alas! There was nothing she could do to earn that freedom.

But what if she didn't have to earn it by herself? What if there was someone who could help her achieve that freedom she strongly desired?

Well, Grayfia only began to know the answer when she met him.


Midoriya Izuku.

A happy-go-lucky yet timid man in his late twenties. Brought up in a simple, middle-class household, Izuku was a man who desired to help as many people as he can. As noted by many people around him, he was a pure-hearted soul with a selfless nature. He could care less about the consequences he would face whenever it came to helping people. As long as that person is happy, Izuku is happy. That was Izuku by nature. Unlike the Lucifuges, the Midoriyas were very much supportive of Izuku and his dreams of becoming a police officer. And he had achieved it with his own hands and brains. But Izuku felt like something was missing in his life. The puzzle piece that would make his life complete.

Izuku began to understand what exactly he needed when he met her.


A busy day filled with people moving from here to there and everywhere. It was the norm in Musutafu. Alongside the norm, came the only feat that separated Musutafu from other prefectures. It was a place filled with crime.

But that only resulted in bringing up the police, who prevent crime from further happening. And this is where our male protagonist comes into the picture.

Izuku was not like any other field officer. He was exceptional. He was noted to have no talent or skill when it came to the physical aspects of being a policeman. But he trained hard. Very VERY hard. So hard that no one would ever want to go through what he went through.

Utterly pure hell.

Izuku was the full package. A highly skilled MMA fighter, and top-notch analytical skills. He met the expectations of even the most strict senior officers, who would put him in the most difficult situations.

Izuku mostly worked in the field, where the real action takes place. But he never worked alone. He had the world's best crime-fighting partner he could ever ask, at least in his opinion.

Melissa Shield.

A genius at technology. A prodigy at management. An overall director if you will. Melissa became Izuku's full time partner due to how well they worked with each other. While he was mostly the brawn, she was the brain behind most of the successful operations they have covered to this day.

Now let's see what these two are doing.


"PHEW... That was a wild one," said Izuku as he munched on his cheese sandwich, relishing its cheesy taste.

"You can say that again. I almost felt like we weren't gonna do it," said Melissa as she bit down the fork holding a small chicken nugget.

Both Izuku and Melissa had just completed a task handed to them by their boss. It involved a high-speed chase where a notorious group of criminals were running away with ten billion yen. Izuku arrested them after driving a good 20 miles on his trusty bike.

Now they were on a break as the operation took out a lot from them, even though Melissa was mostly sitting in front of a computer, guiding Izuku through the plans they made.

"So how has motherhood been for you?" asked Izuku.

Melissa swallowed her portion of food before answering, "It's been going steady, actually. The first few years were pretty hectic. But I should've expected that since every other mother out there had gone through the same phase as I did. But I can't say I'm not happy with it. I'm enjoying it. Nina has been the best thing that happened to my life."

Two years ago, Melissa had tied the knot with one of Izuku's colleagues in the police department. It was a wild journey for Melissa and her husband. They were both blessed with a baby girl named Himura Nina. It's been four years since the child's birth and as Melissa mentioned, she enjoyed it. And she would continue to journey on and face whatever obstacle they come across in the future.

"Enough about me. What about you? How's your relationship?" asked Melissa.

Izuku put down his burger and chuckled before answering, "The best years of my life. That's all I can say about my relationship with Gray-chan."

Now wait just a damn minute, son. How in the world did Izuku and Grayfia hook up with each other? - is what you guys are thinking, right?

Izuku and Grayfia met during an operation. Izuku was chasing down a murderer that had to be caught, no matter the consequence. Grayfia just so happened to be involved in it. The murderer used her as a hostage in order to escape. But Izuku didn't let that happen. With skill like no other, he was able to subdue the man before he committed anything more than he already did. At the time when he apologized to the Lucifuge heir, Izuku couldn't help but be captivated by her. Her beauty was completely out of this world. Where in the world was she made? Whoever it was, Izuku wanted to give him/her the Nobel Prize for the most amazing masterpiece ever created in the universe.

Grayfia, on the other hand, couldn't help but develop a fierce curiosity about the guy. There was something...different, about him. He was not like any normal person. He was...was different. There was no other word she could come up with. Sure she may or may not find herself attracted to him, not that she would tell anybody that. But for the most part, she just couldn't help her curiosity about the guy. He saved her from a really, really terrible situation. Her life was on the line and if there was a single spec of error, then death would surely run knocking at her door. But he professionally managed to prevent that from happening.

From then on, they exchanged contacts. Soon they became good friends for almost two years. They had little hang-outs from time to time and they both cherished the moments they had with each other. It didn't take long for them to catch feelings for each other. While Grayfia admitted her feelings for Izuku, Izuku was rather oblivious to a girl's feelings for him. Melissa can attest to that. Every opportunity she took to indirectly confess her feelings to the guy always ended in an error. And errors are something she hates to the core.

But in the end, she didn't even have to try and attract his attention. Because he had come up to her and confessed HIS feelings for her, much to her utter happiness. They became a couple and have been having a steady relationship. They did have little arguments here and there, but it was nothing compared to the love the two shared for each other.

It's almost been three years since they started dating.

"I don't know what I would've been if I hadn't met her." said Izuku, with a smile that could rival the brightness of the sun.

"Your face tells me that. I'm happy for you, Izuku. If I remember correctly, you said you were gonna give her a surprise, right?" asked Melissa, as she took a sip of her milk.

Izuku just smiled and fished in his pocket for an item. He put his hands in front of her, hiding said item. Before he revealed it to her, "Please don't tell anyone about this, okay?" he asked. Melissa hummed in response and that's when Izuku revealed the item. Melissa did a spit-take after seeing the item in Izuku's hand. She coughed a little before frantically speaking, "Y-You serious right now? A-A-Are you actually planning on doing it?"

"I'm dead serious about this, Melissa. I love Grayfia to the point where I don't know what I would do without her in my life. And I know this is a big step for me. And maybe Grayfia if she is okay with this."

"I'm speechless. But I'm still proud of you, Izuku. It's about time you grow up and be a man." Melissa was excited.

"Yeah, I guess." said Izuku with a little chuckle.

Once they were done with their break, they paid for the food and left to their homes, but not before Melissa wished the best of luck for Izuku, as he might need it for the special occasion he has been planning for his girlfriend.

Just what did Izuku plan that was so important?


*CLICK CLACK CLICK CLICK CLACK CLICK CLACK CLACK*

The sounds of typing could be heard.

In front of a computer sat our female protagonist, Lucifuge Grayfia.

She is currently located in the top most floor of the building that house the best business company in Japan. She works as a secretary for the boss himself: Yagi Toshinori. Their business has only progressed when Grayfia came into the picture.

This was one of her many desires in life. To work as the best secretary in the world. She liked being the helper rather than the manager. Even in her house, she mostly does the cleaning.

Grayfia's life had drastically changed when Izuku came into her life. Slowly but surely, he managed to worm his way into her ice cold heart and make her a woman in love. Albeit, he was oblivious to it.

She has been dating Izuku for three years and she can confidently admit, to herself, that she downright loves the man. He was very sweet and very timid on normal occasions. But he was also intelligent, strong, serious when he needs to be and a determined hard-worker at his job. And she loved all of him. There were times where they would both argue about topics they didn't share an interest in. But in the end, she felt like she had gotten even closer to Izuku, emotionally. The more often they fight, the stronger their love for each other grows.

It was 5:30 PM in the evening, which meant her time at work was over. She winded up for the day, packed her belongings, and began her journey home. Izuku's home.

Ever since she secretly became Izuku's boyfriend, she knew her parents would definitely be disappointed with her. So she decided to leave her parents' house and move in with Izuku. She never talked or contacted her parents since then. But she felt freedom like never before. Free to do whatever she wanted, whenever she wanted. And she wasn't going to let go of that freedom anytime soon.

Before she left, however, she was stopped by her boss, Yagi Toshinori.

"Lucifuge-kun" he said.

"Yagi-san" she greeted.

"Just the person I was looking for. There has been a new development and I was hoping if you would schedule a meeting for me as I'm currently occupied with personal stuff."

"It will be done first thing in the morning. I assure you." she replied.

"I knew I could count on you. Well then, I must be off. My daughter has been calling me non-stop asking where I am. You have a good night" he said before leaving.

"You too as well." She said before making her way to the bus station.

An all too familiar car stopped right in front of her. She knew the caretaker of the car. The car window opened to reveal her boyfriend, Izuku. Seeing his face instantly bought a smile onto her face.

"Need a ride?" he asked.

Grayfia answered by getting in the car and giving him a chaste kiss.

"Thanks for picking me up," she said.

Izuku began their journey back home. Which was gonna be quite a while.

"How was work today?" Izuku asked, breaking the silence.

"The usual. Nothing out of the ordinary so far. How was yours?"

"Today I was tasked with an op that needed to be completed at all costs, as my boss would say. I had to literally chase down a group of robbers bagging a horde of money."

"You aren't hurt anywhere, are you?" she asked, her voice laced with concern.

Izuku just smiled at the fact that his girlfriend cares for his wellbeing. "No injuries today, " he replied.

"That's good. I wouldn't want to hear news about my boyfriend sleeping on a hospital bed" she said, smiling a little.

Izuku laughed. "I don't think that's gonna happen any time soon." He said as he took a left turn. They were almost near their home.

"Have you made any friends yet?" He asked.

Grayfia dropped her usually happy expression to that of sadness. "No" she replied.

Izuku used one hand to grab hers and interlock his fingers. Normally she would just tighten her hold but not in a situation regarding Izuku being the driver.

"H-Hey. Hands on the wheel." She frantically forced his hand to be put on the steering wheel. Izuku just took her hand in his, again. This earned him a glare from his girlfriend.

"Relax. Just enjoy the moment, will you? I'm trying to comfort you and all I get is 'Hands on the wheel' " he laughed after tha, finding the notion a bit funny. Grayfia, however, did not find any humor in it at all.

"This is not funny, Izuku. The rules say you need to have both hands at the 10 and 2 positions on the steering wheel at a times. Driving with one hand could lead to danger. Do you not know that?!"

"And I have driven a car one-handed countless number of times before. This is nothing compared to my job. Besides, we are going slow since we are nearly there." He replied, his hand still interlocked with hers.

Grayfia just tightened the hold before saying, "You're just so reckless that I'm afraid you'll get yourself in danger."

"And do I blame you for that? Absolutely not. But you should also know about the term experience."

That was all Grayfia needed to calm down. Till the couple reached home, never have they broken the connection of their hands. It was part of the love language they use to communicate with each other.


Izuku opened the door to his house and entered with Grayfia in tow. His house was pretty big for just one person alone. It was originally built for Izuku and his parents since they have lived in their old house for nearly 20 years. Of course, the parents protested but it was futile since Izuku insisted on buying a new house for the family.

Unfortunately, Izuku's parents didn't even get the chance to settle in due to a bus accident several years ago. It was heartbreaking for Izuku, needless to say. Tears were shed, and their funerals were held but they weren't forgotten in their minds.

It took a while for Izuku to come to terms with his parents' absence. But he still lets his tears fall every time the image of his parents enters his mind. His close friends and family relatives comforted him and it did help, but only to an extent.

The couple were now unwinding and settling in for a nice rest. The house had a spacious hall with an open kitchen to the left and a full TV set on the right. A couch, two bean bags, and other seats similar in style to the couch, we're situated in the center of the hall.

"I'm going to shower. Do you want to join me?" asked Grayfia as she stood near her room's door. She stood in a seductive pose that nearly made Izuku rethink the special occasion.

"I would love to but not today," he said which made Grayfia frown. She was really looking forward to having some intimacy with her boyfriend. She really liked the sight and feel of Izuku's muscular body. Not that she would tell anyone that. Ever.

Noticing her downtrodden expression, Izuku cheered her up, "If it makes you feel any better, I'll make your favorite meal. That good?"

"Hmph, you always find one way or another to cheer me up. Fine. Thanks by the way," she said before hitting the showers.


Grayfia, done with her bath, wore some casual home clothes, which was a simple shirt with the kanji 'T-shirt.' She hated to admit but Izuku was right when he said these shirts were comfortable to wear. She also wore some shorts that exposed her long silky smooth legs.

She went to the kitchen to find nobody there other than some utensils that look like they have been washed recently.

"Izuku!" she called.

"I'm in the dining room" she heard. She then made her way to the dining room. But when she set her eyes on the place, she felt her breath fade away.

A nearly kept table donning a white cloth over which were placed some delicate plates and bowls filled with delicious food. A vase of roses and lilies. And some candles on the sides of the table.

Overall, it looked like a romantic setting fit for a couple like them. She looked to Izuku who was smiling at her reaction. He was also wearing his signature shirt with the kanji 'T-shirt' and some sweatpants

"You... did all this?" she asked.

"Yes" he replied.

"... It's really... beautiful" she couldn't find a better description.

"I'm glad you like it"

"Like it? Oh no Izuku. I LOVE it" she exclaimed. But then she noticed something.

They weren't dressed for the occasion.

"Please give me a few minutes to change my clothes," she said before turning around to quickly change into some better clothes. But she was stopped by Izuku holding her arm.

"We don't need exotic clothes for this. Besides, it's in our home. Changing now would only make it more frustrating in the end. I want us to feel comfortable. That's all."

Grayfia didn't even have the heart to protest against her boyfriend's wishes. He was always so simple-minded yet he always makes it seem really romantic and sweet in the end. Sighing, she turned around and took a seat and Izuku sat opposite to her.

They both clasped their hands together and said, "Itadakimasu."

They picked up their chopsticks and began to eat.

And just like always... Delicious.

Izuku really knew how to cook. While eating, they conversed on different topics such as the news, the latest fashion trends, and such. The couple were enjoying themselves as they continued to chat and eat to their heart's content.


After washing the dishes, Grayfia cleaned her hands and made her way to the living room.

Suddenly, the music system of their house flared to life and a slow song began to play.

A/N: Play the song Running Home to You by Grant Gustin. AKA the flash.

She looked to Izuku, who was responsible for the music as he put his phone down. He walked over to her and extended his hand and said, "May I have this dance?"

Honestly, she was tired and exhausted, no thanks to the delicious food he made. But was she going to pass up on this opportunity to dance with her boyfriend that impacted her life so much? Absolutely... NOT.

Giggling, she placed her hand on his as they made their way to the center of the hall. Placing their hands on each other, they began to move left and right in a gradual pace, swaying to the rhythm of the music.

When the verse came, Izuku began to sing.

Grayfia might get tired of Izuku being reckless and irresponsible when it came to driving. But she never, EVER, gets tired from hearing his sweet melodic voice reaching her ears.

They never broke eye contact as they danced through half the song duration.

Now was the time Izuku decided to make his move.

Slowly, he inched his face to hers. Grayfia saw this and knew what was coming. She puckered her lips as she moved her face closer.

They closed the gap and connected their lips in a small chaste kiss that spoke their love for each other. Soon enough, their small kiss turned into a heated make out session. Izuku took the opportunity to slide his tongue in her mouth.

Grayfia accepted his prodding and opened her mouth to let him in. The only thing that caught her off guard was that she felt something slide in her mouth.

Breaking apart from the liplock after a few seconds, Grayfia put her hand to her mouth and spit out the object that was slid into her mouth.

Her eyes widened in shock and were close to shedding tears. In her hand, was a silver ring

Yes, I said that. A silver ring. With a diamond on top.

She covered her mouth, as an indication of her expression. She looked up to Izuku to see he was smiling.

He then popped the question.

"Lucifuge Grayfia. Will you do the honours of being my wife?"

That's it. That was it. That line was the one thing that broke her. Her dam broke and she let the waters cascade down her face. She lunged at Izuku and hugged him with all of her strength.

This action caused them to fall down on the couch behind. Grayfia quickly grasped his face with her hands and smashed her lips on his.

Izuku was no less than over the moon. His girlfriend finally accepted his proposal.

After a few minutes of passionate kissing, Grayfia pulled away to look at Izuku with her tear stained eyes. She gave him her answer which was a definite, resounding,

.

.

.

.

.

.

"Yes"


Today was the day.

What day you may ask?

Why, it is the wedding day of our favorite couple, of course.

Months ago, Izuku had proposed to Grayfia in the most creative way thought possible. Grayfia was never interested in the kneeling down and open the box type of proposal. She didn't dislike it, she just didn't find it too romantic like what Izuku did to her.

And now she is finally getting married to the love of her life. She couldn't wait anymore than she already had to.

She was currently in the dressing room donning her wedding gown that she bought for herself. She applied some light make-up and did one last preview to check herself. Satisfied with her work, she prepared herself.

She was going to walk down the aisle alongside her manager, who was the closest thing to a family for her.

Exhaling some air, she went to the car that would be taking her to the place where the wedding would be held.

While she was on the way, Izuku was already at the location donning a full white suit with a black tie. To say he was nervous would be an understatement. But he was nonetheless excited for the events to unfold in the near future.

Standing beside him was crime-fighting partner, Melissa and her four year old daughter. Izuku asked her husband to be his best man since he was really close friends with him.

"You ready, Izuku?" asked Rito Himura, his best man and close friend.

"Extremely nervous but, yeah. I'm ready." He said.

After a few minutes, the priest that would be joining the two made his way to the pulpit.

He cleared his throat before speaking, "I request the audience to rise as the bride enters the premises."

The audience that had gathered for this wedding stood up and turned around to witness the bride. The wedding march had begun to play in the background.

It didn't take long for the bride to come into view of everybody. Jaws dropped at the beauty that was Lucifuge Grayfia. Even Izuku, who had the pleasure of seeing her in more than one form of apparel, had his mouth agape at his future wife's appearance.

She was stunningly beautiful. That's all they could describe her to be. Nothing more, nothing less.

She finally reached the pulpit and stood to the right of Izuku as they both gave each other a glance before turning to the priest.

"Please be seated." The audience did so.

After that, the programme began and Izuku and Grayfia just stood there with extreme nervousness while listening to the priest.

Then the time came to exchange vows.

"Do you, Midoriya Izuku/Lucifuge Grayfia, take Lucifuge Grayfia/Midoriya Izuku to be your wife/husband, to have and to hold, from this day forward, for better, for worse, for richer, for poorer, in sickness and health, to love and cherish, until parted by death?"

"I do/I do" said the couple with utmost sincerity and honesty.

"Then I now pronounce you husband and wife"

The audience cheered and applauded the newly wedded couple. Izuku gently lifted the veil on her face and gave her a passionate kiss with Grayfia throwing her arms around his neck to bring him closer.

They were finally married and while nervous and slightly afraid of the future that awaits them, they couldn't be more happier than to be with each other.

Grayfia's life was impacted by Izuku.

Izuku's life was impacted by Grayfia.

Both couldn't do without each other.

And that is the story of their undying love for each other.

A/N: PHEW... That took a lot out of me.

I hope you guys enjoy this rarepair oneshot.

Who should I do next? Let me know in the reviews.

Also, do tell me whether I write good or not. Whether I have improved from my previous one-shots.

Because I want to give you guys the best there is I can.

I'm planning on writing a full Highschool DxD story with Izuku as main character. There is no issei. It will be different compared to canon. I will not follow canon at all. It will only be at some points.

Dragon Out.
