So... this is just a simple one-shot series with every character from Karasuno (and some others) and their designated OC's :D Now, usually I would write my whole story before posting anything, but as I am in between writing another story at the moment, I need something to kind of take my mind off of it sometimes. Something light-hearted that's easy to write.

And so, the Haikyuu one-shot series began!

So yeah, like I said, usually I write the whole thing before I post, but with this story I will be updated as I write it. And considering I'll be writing another, full story, in between writing this, the update schedule for this may be a bit awkward. You may get two or three chapters in a two day time period, or you may get a chapter every couple of weeks.

We shall see.

Quick mention to my cousin, who is also a fanfic writer within the wonderful world of Fanfiction. Her screen name is jessicuhxoo. She writes mostly Pokemon fanfic, with some Fairy Tail here and there. The reason I'm mentioning her is because she is the one that helped talk me through these ideas for these one-shots during one of our pool talk sessions.

So yeah, thanks cuz!

Now, on with the story! I hope you guys enjoy! This, so far, has been really funny to think about and write, so I hope you guys like it as much as I do!

DISCLAIMER: I do NOT own Haikyuu!


Hinata x Aiko (OC)...

"Oi! Hinata, come here for a second!"

Hinata looked over at Coach Ukai, who was standing off to the side of the court waving him over. He nodded his head.

"Hai!"

Without paying any attention to his surroundings, Hinata dashed towards the older man, only to be pegged off the side of the head with a stray volleyball.

"Idiot! Watch where you're going!"

Hinata's face flushed in embarrassment.

"O-oi, shut up Bakeyama!"

Kageyama sent a sharp glare his way. Hinata stuck his tongue out at the onyx-haired boy and continued making his way over to his coach.

"You okay there?" Ukai asked Hinata hesitantly. Hinata was definitely not a stranger to taking a few hits upside the head, and even more to the face, so he wasn't too worried. However, it was always good to just double check.

"Mhm," Hinata mumbled, rubbing the side of his head with a sheepish smile on his face. "Sorry, what did you need coach?"

"Right," Ukai said. He held out a folder, "I need you to bring this to gym number 3. It's one of the outdoor ones."

Hinata grabbed the file and nosily started pulling it open to look at its contents, "Ooo, is this like, top secret information or something? So cool!"

Ukai swiftly slammed his clipboard down on the orange-haired boy's head.

"It's boring financial stuff. Just go and bring it to the coach out there, will ya?"

"Yes, sir!"

Hinata booked it out of the gym and ran along the perimeter of the school towards the fields and courts outside. He watched as the soccer team did their warm ups and even passed by the swim team as they made their way towards the pool.

As he made his way past the basketball courts, however, he slowly found himself coming to a screeching halt.

Peeking curiously at the players on the court, Hinata quickly realized that a) it was the girls' basketball team, and b) they looked like they were about to play a 3 on 1 match.

"Ohhh…" Hinata watched in wonder, crouching down behind the bushes as they continued on with their match.

While watching them play, Hinata started to realize that the team of 3 was scoring WAY more points than the girl that was by herself.

'Well, that's just not fair," he thought to himself. They were obviously creaming her, so why did they let her play all by herself if she wasn't amazingly good?

"Can I help you?"

Hinata nearly jumped ten feet in the air and whipped around so quickly he thought he had given himself whiplash.

"Wah!"

"Haha, you should have seen your face!"

Hinata felt his heart in his throat. While his pulse came down from the stress of being frightened so badly, he finally started to realize that there was, indeed, a girl standing in front of him.

She was about his height, maybe a half an inch shorter, and had dark red hair pulled back in a high pony tail. The smile on her face was blinding while she laughed at Hinata's misfortunes.

"Haha! That was great!"

Hinata felt the blush spread intensely across his cheeks. He coughed a bit awkwardly, not knowing what to say.

The girl exhaled, "Anyways, back to my question from before. Can I help you with something? You look kind of creepy over here in the bushes."

Hinata immediately straightened from his crouched position in the shrubbery surrounding the gated basketball court, "Ah, no! I was just- uh, watching is all."

The girl's eyes lit up, "Really! Well then, why are you standing out here silly? Come on, I'm late anyways."

Before Hinata had the chance to protest, she had grabbed him by the wrist and dragged him onto the court.

"Aiko! Where the hell have you been?!" a scary looking girl with glasses shouted from the benches. The girl, who Hinata now knew as Aiko, chuckled with a sheepish expression on her face.

"Oh, you know. Just here and there…"

"Don't give me tha- Hey, who's this?"

Aiko turned to Hinata with a wide smile, "Oh, I found him in the bushes! He wanted to watch!"

The girl with the glasses stared at Hinata with a straight face, "In the bushes?"

Hinata gulped, sliding slightly behind Aiko for protection despite the bit of a height difference between the two.

"Yeah!" Aiko confirmed with a big thumbs up.

The other girl sighed, "Whatever. Just hurry up. Kid, sit."

Hinata nodded vigorously, not even bothering to remember that he had his own practice to get back to. No, that girl was scary and there was no way he was going to double cross her any time soon.

He took the seat furthest away from her on the bench before looking over at what was happening on the court.

He saw Aiko flex her arms from the side lines before she raised her hand to be let onto the court. The girl playing against the other three quickly noticed this and called for a time out. She ran over to Aiko in relief before she switched out with her, leaving Aiko to take her spot on the court.

"Thank god she got here when she did," the girl mentioned as she made her way over to the bench. She grabbed one of the towels sitting beside Hinata and wiped the sweat she had accumulated from her forehead. "I thought I was going to die out there."

Hinata's brows furrowed in curiosity. If playing against three people was so hard, then why did Aiko look so happy to go out there?

Hinata continued to watch, all fear of the woman beside him completely gone as his eyes tailed Aiko with a new-found intensity.

She stepped in front of the three young women with nothing but a wide smile on her face.

"Ready?" she asked them.

They nodded, one wiping the sweat from her brow while the other two ignored the sweat and dropped down into their ready positions.

They all waited there in silence.

And as soon as the whistle blew, however, Aiko was gone.

Hinata tried to keep up with her, he really did. But he wasn't expecting her to move so quickly! All he could see was a blur as she came to a stop at the edge of the free throw lane and leapt with all the grace of a tiger, slamming the ball into the hoop.

She landed on the court with a satisfying 'thud!', crouched low like a wild animal stalking its prey. She slowly stood, turning to face the other three opposing players who could only stare at her in annoyance, already used to the way she plays.

Hinata on the other hand, could only stare at her in amazement. He had never seen somebody jump so high! Not even himself! And she was even shorter than him!

"W-w-whoaaa!"

Everybody turned towards him, most with confused expressions, not knowing who the hell he was or why he was there.

Aiko, on the other hand, lost the intense look she had gained during her speedy slam-dunk, only for it to be replaced with another one of her radiant smile.

"That was so cool Aiko-chan!" Hinata exclaimed, standing up from his seat on the bench. His arms flailed to prove his point.

Aiko blushed lightly at the name, "Heh, really? I guess… If you think that's cool, you should see me really play!"

"Whoooaaa, that wasn't even you serious? You're so cool!"

This only seemed to inflate the girl's ego, leaving a smile on her face that was brighter than the sun, "Thanks!"

The girl with the glasses shook her head, mumbling something about "there being another one".

"And then you went WHOOSH! And then BANG!" Hinata illustrated with his own movements, Aiko now standing in front of him watching him closely with her own sense of excitement. "And you jumped so high! Even higher than me!"

"Than you?" one of the other teammates asked.

"Oh yeah! Sorry, I forgot to tell you. My name's Hinata, Shouyou and I'm actually on the volleyball team! I'm gonna be the ace some day! Just like the Little Giant!"

Aiko gasped, "I've seen the Little Giant on TV before! He's so cool! I'm gonna be the ace too someday!"

"Really?!" Hinata asked, his eyes wide with excitement and wonder. "Oooo, that's so cool!"

"Yeah, they all tell me I'm too short, but I'll show them!"

"Exactly! I may be short, but I can fly!"

"So can I!" Aiko added.

They both shouted simultaneously before high-fiving each other.

The rest of the basketball team had decided to simply ignore the two and return to practice, not wanting to get caught up in between the two sunshine twins as they ranted on about their future dreams and aspirations.

"Can I see you play volleyball some time?" Aiko asked Hinata hopefully.

He nodded, "Yeah! And maybe I can come see an actual game of yours too!"

"That would be awesome! I'm really happy I found you in the bushes Hinata. What were you doing in there anyways?"

Hinata chuckled in embarrassment, "Oh well actually…"

He suddenly froze.

Aiko looked at his now pale, blank face in confusion. "Hinata? You okay?"

"I-I forgot about practice."

Aiko tilted her head in confusion, "You had practice?"

"I've got to go Aiko-chan! See you later!"

He quickly sprinted away from her, out of the gated court and down towards the indoor gyms on the other side of the school.

"Huh," Aiko mumbled quietly to herself. "That was weird…
