Hey, guys! GOTA, here, with another solo story. These are my first few stories without having BD to assist. In this MHA x RWBY crossover installment, Izuku wakes up with a hangover and discovers Yang sleeping beside him. They are drunk, hungover, and married? What tails will ensue these teens? Read and see! This is an OOC Yang x OOC Izuku love story. Enjoy!

"My Songs Know What You Did In The Dark" by Fall Out Boy penetrated his ears in a harsh manner. What was his morning alarm was becoming more of a hindrance. It was midmorning and his head felt like a scythe was implanted in it. He struggled with his eyelids, trying to intercept his cell phone from where he last put it. Izuku began fumbling with his hands as he reached out to grab his cell phone. Immediately, he put it on mute. Never in his sixteen years did he feel a hangover as horrid as this.

Matter of factly, this was the first time that the emerald-haired teen encountered a hangover.

He rubbed the bridge of his nose to relieve an itch. Then, a crest of light from the heavily draped curtains hit his face. Like a vampire, he reached for the duvet to cover himself in darkness. It was too early for the sun to be this demanding, this harsh ironically to the Sun God.

The artificial lighting from his cell phone didn't help either. Izuku was becoming more aware of his headache than the layer of dehydrated saliva that coated his cracked lips. He shut his eyes tightly so he could be coherent as he could see who was trying to call him at this ungodly hour.

While gripping on his phone, he was trying to recall the events that led him to his current juncture. One thing was for certain, he didn't recall having heavily draped curtains in his dorm room. Another thing was he didn't recall having such a silky duvet. Despite his father being a salaryman working overseas, his father dearest was too much of a cheapskate to give him that kind of luxury.

Feeling as those he could manage his vision, he decided that his phone could aid him in the backtrack of events. He clicked on his phone tab to check his recent calls. Rows and rows of his classmates were attempting to call him. Katsuki called him multiple times between 11 PM and 2 AM. Shouto made several calls around the same time. Ochako, Tenya, Momo, and a few others were calling him. Then, he clicked on his text messages.

Dude! Where in the hell are you? Call us!

Deku, are you okay? We are worried. One moment we were dancing at the club, the next you disappeared. Call us!

Midoriya, this is Yaoyorozu. Where are you? We are worried sick. We checked throughout the garden district and we couldn't find you. Call us so we won't fill out a missing persons report. Nezu would kill us if he finds out that we snuck out last night. Please give us a call or a text.

Lucky ass bastard! I knew somewhere in that defenseless, meek, and timid body was some cajones. Great job, baka!

His first clue was revealed. It was on a whim of a dare. It was after school when he and a few classmates were sitting in the classroom as they were thinking of plans for the three-day weekend. A school holiday was approaching so many of his peers were deciding on how to make fun, action-packed, adventurous, and unforgettable.

Bakugo knew a guy that could let us in the bar. Of course, we had to give him a few dollars as a finder's fee. I remember Iida, Todoroki, and I went shopping to find some clothes since the bar was a bit ritzy.

His brain felt like it would swell beyond the capacity of his skull and now his dehydration was too obvious to ignore. However, the swaying of the room was getting to him. Generally it wasn't a good sign and the urge to vomit was pending.

With much of his might, he forced himself to sit up. Upon doing so, his stomach gurgled and lurched. He had his eyes fixated on his cell phone. He saw that he had a voicemail. When clicking on the voicemail, it came from an unknown number. He didn't recognize the number or its area code. The calling number was certainly not a Japanese number. Knowing that he would have to figure out an excuse with his mother on the next phone bill, he decided to listen to the message.

Hi, cutie! This is Blake! The girl with the neko ears, you say! Listen, I wanted to say that you better treat my friend right on this night. Tonight is her birthday and I am not sure where you two are going, but you better treat her like the princess she deserves to be. Thanks for giving me your number. You're such a gentleman. It's a shame that I didn't intercept you first, but please take care of my Yang. Bye!

His second clue was revealed. Izuku was processing the events that led to his being in this bed. He groaned while massaging his head. He remembered being at the club. He took a taxi cab to head Downtown. He was one of the last of his classmates that arrived there. Before he headed to the club, he was met with a lecture from his mother. Word through the grapevine spread quickly to her. Despite having her reservations, she was going to put trust in her son that he would do the right thing, being responsible.

Several hours prior….

This party at the club? Will you be interacting with girls?

Well, maybe? Talking, relaxing. Maybe a dance or two? I do have two left feet.

Sweetie? Did you pack any condoms?

Mom?! Nani?! Really?

Hai! Sou desu ne! Yes, really, Icchan! I am aware of what these girls could do to you and you are not bringing me home a granddaughter.

Mom! I doubt I will be going that far.

I know, but it's not for you. IT'S FOR THEM! I don't trust those whores.

Mom, I won't involve myself in that. It's to have a great time.

Still, I don't trust those sluts. But, I trust my baby. So, here you go and have fun. And remember: no granddaughters!

Back to the present….

The room began spiraling once more. Not only it was due to the alcohol, but the pieces that were now connecting.

Blake? Yang? Club? Birthday?

The birthday punch!

I was at the club. I went to the bar. I was trying to search for my friends, but I couldn't find them. As I sat at the bar, the bartender gave me a drink. He explained that it was on the house from this blonde foreigner.

Yang!

It was her birthday. She was visiting Japan with friends. She invited me to her table. I met her friends. They introduced me to various drinks. We danced, we sang karaoke. I danced with Yang. We were dirty dancing. She danced behind me. She gripped onto my hips. We grind to the beat. We started kissing. We were tongue kissing. We went to the restroom. Oh, God!

He slowly pulled the duvet from him and realized that he was naked. Instantly, he covered himself. Initially, he should have realized that the room was a bit drafty.

He shut his eyes once more. His thoughts returned to what his mother had told him. He grabbed the duvet and used his cell phone to showcase his penis.

A grim thought entered his mind when seeing that there wasn't a condom in sight. However, certain bodily fluids were covering his member. Dry patches of red and white were present. His breath began laboring once more.

He swallowed his lump in his throat as he shifted his head to the left side of the bed. He pursed his lip when seeing there was another person beside him. He slowly lifted the duvet to discover the person in question.

Upon doing so, his fears were confirmed.

Rivers of yellow covered the woman's face. Her hair was unkempt and she, too, was naked. Her breath reeked of alcohol. Upon recognition, it was the girl that he danced with at the club that night.

Yang Xiao Long!

She appeared blissfully happy. Her face was flushed. Instinctively, she reached for the duvet to cover herself from the cool draft. She smacked her lips as she turned over. Izuku began panicking. He didn't know what to do. Fearing the repercussions from the blonde foreigner, he observed his surroundings to find his clothes.

It appeared that they were at a love hotel. Judging by the assorted colors of hearts on the wallpaper, the coin slot for the vibrating bed, and the large mirror on the ceiling, it had to be the love hotel that was owned by the Shiozaki family.

Now, there were two reasons to feel grimaced. Especially if word gets out from Ave Maria herself.

Slowly not wanting to disturb the sleeping damsel, he slowly stepped out of bed. As he swung his bare feet to the carpet again, it was cold and sticky underfoot. His flushed face flattened. He must have missed that earlier. One bleary look told him where the peanuts and alcohol of yesterday could be found.

A few minutes later….

Izuku's clothes were wrinkled and drenched in perfume. Lipstick smears were all over his collar and a few buttons were missing. When inspecting himself in the bathroom, his neck was covered in hickies. There were presence of bites marks on his chest and scratch marks on his back, even to the point when skin was broken.

It was difficult putting on his clothes, using the wall as support. He couldn't find his boxers so he had to go commando until he headed home. He replied back to the others and produced a lie that he was spending the night with his mother and won't be back at the campus until later that day. It gave the emerald-haired teen some borrowed time before thinking of the next plan.

Especially on what he saw laced around his left ring finger.

He was managing to keep standing while he was somewhat staggering. At some point, housekeeping was going to alert their departure. He returned back to the room as he was searching for Yang's clothes. He had managed to find them as they were scattered in front of the hotel door. With struggle, he managed to pick them up and placed them on top of their bed.

It was now for the moment he had held back since discovering her in bed.

He walked to her side of the bed. Slowly, he used his hand to nudge her shoulder.

"Yang! Yang! Wake up, Yang," urged Izuku.

She used her hand to swat his hand. She smacked her lips. "Five more minutes, Ruby."

He nudged her again. "Yang! Wake up!"

She swatted his hand again. "What did I just say, Ruby? Leave me alone and bug off!"

Izuku didn't like what he had to do. "YANG!"

Immediately, hearing his shout penetrated the blonde's ear. She groaned as she covered her ears. She turned her head and faced the person in question. Upon seeing the emerald-haired teen, she slowly produced a smile. "Oh, hey! Good morning, baby!"

Good morning, baby! Izuku was startled. That wasn't definitely what he was expecting to hear.

She stretched her arms, exposing her breasts. Immediately, the teen averted his eyes. Of course, he had seen his mother naked when they used to take baths together, but this was the first to witness this.

Yang scratched under her arm. "It's morning, isn't it?" She grabbed her scroll on the nightstand and looked at the time. "Hey, where are we?"

Izuku positioned himself to the wall. "We are at a love hotel."

She pursed her lips before producing another smile. "Yeah, we did get crazy last night, didn't we?" She winked at him. "By the way, thank you for a wonderful birthday. It was a blast." She patted her lap. "So, where do you want to go for breakfast?"

This direction was unexpected to the teen. He doesn't hear any sign of regrets, frustration, aggravation, nothing. He ingested some air before needing to explain what was next. "Yang! Are you aware of what is happening?"

"Yeah, you silly goose," she said calmly. "Last night was my first night in town. It was my birthday and we decided to go to this club to celebrate." She winked at the surprised teen. "That is where we have met." She made a growl. "I must say, Izuku! You were a tiger on the prowl. You definitely made me purr."

"Don't you feel some kind of drunk, Yang?"

Yang looked perplexed at Izuku momentarily before the realization of their current juncture. She began to laugh.

"How is that funny," questioned Izuku.

She wiped the tear from her eye. "Sorry, sweetness! I can hold my liquor like a Spartan." She lightly tapped her head. "Too much of my mother in me. That annoying little bitch!"

"So, you aren't aware of the ring on your finger," questioned Izuku nervously.

"What ring," retorted Yang. Her crimson eyes focused on the wedding band on her left ring finger. Unlike Izuku's wedding band, it was a combination of green and yellow. She stared momentarily before realizing the situation.

"Oh, hell," she said. "I must have been super wasted!" She rubbed her fingers through her hair. She, then, looked at the cinnamon roll in question.

"I am surprised that you are calm," said Izuku.

Yang sighed. "I've been through worse. Let's say I am a bit of shock right now."

"Strange, but okay," replied Izuku.

"Let's not panic too much. Let's have breakfast first so we can straighten things out." She lowered her eyes. "Unless you have other plans."

Izuku nodded in disagreement.

"Okay, good!" Yang stretched her arms as she was getting out of bed. "I am going to take a shower. Feel free to join me if you want, sweetness."

Izuku stood motionless as the naked Yang was entering the shower before closing the door. He was surprised by her nonchalance. She was too calm. Anyone that had drunken sex and woke up being married should be panicking.

Married? Yang and I? Married?

It finally clicked in his head. He was married. He had the rings to prove it. He began stretching his collar. He backed away. Sweat was evacuating from his forehead. "Man, it's getting hot." He began staggering. "It's getting hot in here, so take off all your fur," he sang melodically. "I am getting so hot. I'm gonna take my fur off." He fell backward, fainting on the ground.
