Been really busy with work and life in general but I just have to write this fanfic!

Despite his shittyness, I am a big Oikawa fan (don't judge me!) and I am so in love with the Haikyuu series that I have to write something and I thought, why not a crossover?

I got this idea after watching a Kegayama AMV with Unravel music and it was just beautiful. I thought it would be interesting to see how Oikawa would deal with this situation and I do have an interesting but pretty messed up idea on what to do with the next few chapter hehe.

For now, just sit back and enjoy this story!

I don't own the characters (which sucks big time!).

Oikawa Tooru sat on the bench, removing his knee protectors as Iwaizumi came in, the door slamming behind him.

"Hey, Shittykawa. First time you're leaving practice on time. What's gotten into you?"

"You did recall me having a date with Sawa-chan right?"

"Why are you even going out with her when you don't even have time to take care of yourself? You literally breathe and love volleyball. You don't have the time for a girlfriend do you?"

"If I never try, who knows. Besides, it's not like you're one to give me advice when you can't even get yourself a girlfriend."

At his words, Iwaizumi sighed as he backhanded the back of Oikawa's head, making the setter winced as he muttered, "That hurt, Iwai-chan."

Both boys changed in silence for the timebeing, the sound of moving bags and clothing filling the silence of the locker room. Oikawa had excused himself from practice earlier and Iwaizumi had gotten a bit worried about something happening to him. Oikawa never left a practice right on the dot, period. He was always lingering around at least for two hours after practice, trying to practice his serves.

"Just be careful. With the news of ghoul attacks increasing in Miyagi, you might want to get home before dark."

Oikawa snorted as he threw on his shirt. He would have to deal with smelling a bit as he got ready to head out. Sawa was supposed to wait for him at the school gates and he felt a little bad about having to make her wait for so long after school hours.

Come to think of it, he didn't even know much about the girl, just that she was a student at his school. Apparently, she was in the class next door and while he had always had to deal with a horde of fangirls trying to profess their love for him, she was a unique case where she actually got straight to him and asked him out.

He felt pity that he would have to reject her after the date.

Iwaizumi was right. He had only the time to focus on volleyball and nothing else. With Kageyama now in high school and being a much more formidable setter than ever, he had to push himself to the limits or else he would never beat his annoying junior. He couldn't wait to wipe the floor from him the way he did when he first appeared in Kitagawa First, outshining everyone and especially his hard work and pride.

"I'm going."

"At least don't make her cry so hard, Shittykawa."

Oikawa snorted as he slammed the door behind him, the air hitting him in the face. It was going to be a pretty hot summer this round and he was hoping he didn't smell too bad for his date. Hopefully, the air conditioning of the café he booked for them that evening would cover for it. Or maybe she just liked the smell of a sweaty boy.

Sawa waved at him from the school gates, her twin braids bouncing on her shoulders as she smiled, red glasses perched on the end of her nose. Some of the other girls passing by snickered as they passed, whispering about her as they did so. She didn't seem to care though as she walked towards him.

"Hi, Oikawa-san! How was your practice?"

"Not bad." Oikawa sucked pretty bad with one on one conversations with girls. At least with a crowd, he could easily deflect questions and use his charms to calm them down and for once, he was a little intimidated about the situation.

Both of them walked down the street into the main city center, the sun already turning the sky into a pretty orange as they entered the café, the bell tinkling above them. The waitress led the pair to a table in the corner, giving them enough privacy as she handed them the menus.

Oikawa wondered how in the world he got into this situation. Before this, the only thing he had on his mind was playing volleyball until his body tore to pieces but now, here he was sitting across a girl who he thought wasn't the prettiest in town and just happened to have the guts to ask him out.

"What are you going to eat, Sawa-chan?"

"Um… I think I'll just have sandwiches and a coffee."

"You shouldn't be eating so little. Girls need to eat more to grow."

Sawa blushed as she hid her face in the menu, murmuring to herself as her eyes scanned the pages. When doing that, she looked a little cute but Oikawa had already set his mind on what was going to happen next.

As they ate, they talked a bit about what was going on in school. Other than volleyball, Oikawa had literally no idea on what to talk on with a girl so he just got to ask her about classes while mentally cursing himself for being such a bad date. Sawa didn't seem to mind though, a mysterious smile playing on her face as she ate. Oikawa felt a little bad with the heap of food he had in front of him but he managed to finish it all rather quickly due to the amount of energy he burned in volleyball practice just now.

By the time they left the premises, night had fallen and the streetlights had flickered to life, lighting their way as they made their way home. Oikawa was starting to think that the whole thing had been a waste of time when he heard the newsperson on the tv speaking as they passed by an electronics store.

"Ghoul activities in the Miyagi prefecture has been rising lately. We have here an investigator from the CCG, First Class Investigator Kaname. Welcome to the show, Investigator Kaname."

"Thank you. The CCG has taken measures in sending more personnel to patrol the area and deal with any ghoul activity. Please make sure to stay safe at all times and not to linger after nightfall unless absolutely necessary. Ghouls wander among us and they may look like normal humans, but underneath that disguise, they're flesh eating monsters. While we don't know how the ghoul population came into being, the best we can do is to send them back to the hell that spawned them."

As the investigator spoke, Oikawa felt a little chill down his spine as he glanced at Sawa. She was quiet the whole time, not speaking as much as she did in the café. Maybe she was just a bit tired. Then he turned back to the tv and chuckled to himself. There's no way there could be a ghoul with him right now. It had to be really random for him to even bump into one, heck, maybe they didn't even exist and the government was just toying with them.

"Oikawa-san?" Sawa whispered as Oikawa came back to focus, turning to smile at her. "Ah, Sawa-chan. I think we should head back now." His mind swam as they continued to walk, not noticing that they had arrived in a tunnel area.

"Wait a minute, Sawa-chan. I believe your home was in the other direction…"

As he spoke the words, he heard a giggle and a piercing sensation in his abdomen. He coughed blood as he gazed at the kagune protruding from his stomach, his innards starting to turn into mush as his mind went, "Oh shit…"

"Ah, Oikawa-san. I knew that you were just going on this date with me to make me feel a little happy. You think I didn't know that you would dump me outright after our little date? Don't you worry, I'll make you all mine. Ah, you smell so delicious, like Salonpas and sweat… I can't wait to devour you!"

Oikawa clung onto the kagune as he was thrown through the air, smashing into the wall as she cackled with glee. Panting, he tried to rise when he noticed the construction site nearby. "Bingo," he thought as he limped towards the site, blood trailing in his wake as he limped. Oh shit, how am I going to even heal from this wound?

"Come on, don't be shy! You should be honored to be eaten by a ghoul! Your flesh won't rot and go to waste!" she crooned as she walked after him, humming a little tune under her breath as Oikawa gasped. He was slowly losing consciousness and just to stay awake took him everything he got.

"Oh come on, just die already! I'm getting really hungry!" Oikawa felt his body leave the ground as he was smashed into the skeleton of a building, steel beams crashing around him as he coughed. Oh damn, was he going to die without even getting to beat Kageyama and Ushijima? What a joke…

"Come to mama!" she shrieked as she lunged, her kagune aimed for his throat when the structure started to collapse around them.

"What?!" Sawa shrieked as a steel bar fell on top of her, crushing her flat, her screams filling the air just as Oikawa blanked out.

…

Oikawa was floating in the darkness, his naked body floating in the water as he tried to rise to the surface. His legs wouldn't move and he was starting to lose air as he reached out. "Come on," he thought as he felt himself fade away. As he begged to just be free of the pain, more thoughts pierced his mind.

Memories of him playing with Iwaizumi and both of them getting on to their volleyball team, both of them becoming an unbeatable duo and captain and vice captain of Aoba Johsai. The sadness and rage they felt when Shiratorizawa crushed them over the years, Ushijima looming above them. Last of all, the sad voice of Sawa, the girl who may have just killed him whispering, "I just wanted to feel love like a normal human…"

With those thoughts, Oikawa felt himself get dragged to the surface and awoke to find himself in a hospital room. The lights glared at him as he slowly opened his eyes, his stomach feeling very empty as he tried to move. There was a mask on his face, oxygen being delivered into him as he looked around. The place was empty save for him and a bedside table full of getwell gifts. He could almost imagine Iwaizumi-s red face as he brought in the balloons into the room, Maki and Matsun pushing him along with Kindaichi and Kunimi at the rear.

"Ah, Oikawa-kun. You're awake," the doctor smiled as he came in, a nurse following suit as they went to check him. Oikawa was surprised he wasn't even in the ICU, considering he was dying with a hole in his stomach about… what day was it?

"How long have I been out?"

"Oh, about three days."

Oikawa didn't even want to imagine all the stress he must have caused his family. His mother would probably be freaking out now about her youngest being in the hospital and not to mention his coach would murder him once he went back for practice, which he won't be able to do in a good while.

"Everything looks good. Right. You should be free to go in a few days."

Oikawa just nodded as the nurse checked on him and by the time they were finished, he was lying on his bed, just gazing out of the window. He didn't know whether to believe everything that had happened so far was real, from Sawa turning out to be a ghoul and him landing in the hospital. Then there was this sinking feeling of emptiness in his gut.

"Oi Shittykawa!"

A familiar voice came from the doorway as Iwaizumi came in, clad in his volleyball uniform followed by his mother and Oikawa-s own mother, who had a handkerchief to her face as she hugged him.

"Hey, mum. It hurts!"

"Tooru! How did you get yourself into such a mess! I was worried sick!"

Iwaizumi's mother gently pried her off as Iwaizumi cuffed him at the back of the head. "The doc said you should be able to go home in a few days but I don't know when you can get back to practice."

Oikawa clenched his fist, thinking of how much precious time he had lost spending recuperating in the hospital when he could be defeating Kageyama and Ushijima on the court. "Don't worry, Iwai-chan. I'll make sure I'm back on the court in no time."

The boys bumped fists with each other just as the nurse came in, wheeling a cart of food for Oikawa. "I think we'll leave you to your food," Iwaizumi murmured as he shooed the other two women out of the room, leaving just Oikawa and the nurse as she placed the tray on the table. It was one of his favorites, salmon, rice and some picked radishes but something was off about the smell like it smelled of burnt tires or something…

Oikawa gulped as he picked up the chopsticks and picked away at the fish, bringing it to his mouth and gulping it down only to taste something like rotten fish in his mouth. He gagged as he spat it out, not being able to hold it in as the nurse raised an eyebrow. "If you didn't like it, you don't have to spit it out, Oikawa-kun."

Oikawa's eyes watered as he stared at the food, now looking more like poison to him than food. He didn't dare to attempt another bite and the nurse sighed as she picked it up and brought it out of the room, leaving Oikawa to wonder if something was very wrong with his body.
