Disclaimer: I do not own Haikyuu

This fic has been on my mind for the longest time and I'm itching to write it. Also, there's not much gendebender fics out there, so here you go. :-)

Basically, this is what I think will happen if the main protagonist is a female. Sorry in advance if you think some characters are OOC. :-)

1.

Suga never thought that being a vice-captain-slash-babysitter of the team-slash-mom of the team (as Nishinoya always calls him-though the reason behind it, he doesn't know) will cause him to age like twenty years in advance and gain a reputation within just a week of the training camp.

The reason? His kohais(though obviously it's always about them and God help him- if his silvery-white hair can only turn whiter), and nothing prepares him from what he is seeing in the afternoon of the fourth day of the training camp.

Even Daichi, the strong-willed, responsible, often calm but slightly scary third year captain of the team is gaping at the sight while stting down on the floor to rest. Asahi, who is doing the same thing, turned his gaze on what their captain is staring at and immediately gaped like a fish.

Near them sitting on the bench, Coach Ukai has his mouth open, apparently to say something, but can't seem to form any words as he too was confused and appalled. Beside him, Takeda just sweatdropped.

Tsukishima tries to wear an indifferent expression, but the slight widening of his eyes betrayed his true reaction to the current situation. His bestfriend though-please bless the poor Yamaguchi, cannot stop his squeak and red face, his face torn between embarassment and awe.

The three second years, namely Ennoshita, Kinoshita and Narita, all in turn switched their bewildered gazes from the current center of all attention to the two unnamed second years, who we all know is the most troublesome duo. The two both look excited and doesn't bother to hide their awe, oblivious to the fact that Suga is drilling a hole on their faces.

"Ohhh! She really did it! I need my camera for this!"

"Wow, Shoyou! You look-"

"What's the meaning of this?" the vice captain calmly asked, though the overwhelming dark aura he's producing causes the Karasuno's wing spiker and libero to flinched at the sight. Neither of them can utter a word as Suga started to smile sweetly. "What did you made Hinata do?"

"I think it's obvious, Suga-san." Ennoshita deadpanned. He looked around trying to find their main setter, wondering how he would react to this. He noticed the other teams also staring in their direction, and he thought he heard someone shouted "Unfair!" from the group of cats. How troublesome.

The team had just finished their tenth match for the day (which they lost again against Nekoma), and they have one more to go before practice day ends. Apparently, the Karasuno team added one more punishment for their team, particularly on one person who will make the most errors on their tenth game (the one who's behind this ridiculous idea-he doesn't know or bother to remember). The loser will pick a dare and needs to do it before the day ends.

And well, guess who lost.

As if on cue, the missing raven-haired first year appeared from the bathroom after a quick break. There's a visible tick mark on his forehead as his face is wearing its usual frown. "Hinata-boke! Where have you- huh?!"

He stopped, eyes staring at the strange sight before him. No, strange was not the right word, rather, it's... breathtaking.

Hinata Shoyou, though biologically a female at birth and possessing one of the cutest faces on earth (something Tsukishima and Kageyama would never admit) is not known for being a normal, girly, highschool girl. While most of the girls around her age would like to think about romances and like to wear skirts and dresses, Hinata would rather think about volleyball and usually wears a simple shorts and a bit of an oversized shirt so she can play her beloved sports with ease. She usually hangs out with boys and rarely talks to girls (except Yachi and Kiyoko), is usually loud and competitive, and most of all-oblivious to affections and stuffs about teenage love. Such characteristics make her teammates almost forget she's not a dude, and only on sudden occasions like a beaming smile, pouting face, and ehem, womanly curves will wake them back to reality.

However, this reality hit them hard like a wave on the face today, as the blushing form of the said girl fidgeted from her place inside the gym while wearing a cheerleading outfit. A black cheerleading outfit. Where she got those clothes from, they don't know.

Wearing her hair today into two pigtails tied by two black ribbons, she had her arms wrapped around her midriff, trying to cover the exposed area of her skin where her cheerleading top stopped at its length. Her black skirt, though not very short, still reveals her white legs and her feet are wearing a pair of white sneakers.

Still with an embarassed face, she looked into Suga's eyes and slightly whimpered. "S-sorry Suga-san. I have no other choice... it's not like I like this either?"

"Still... coming up with this kind of dare..." Suga glared at the two masterminds again.

"W-well... it's not like we asked her for this kind of dare either!" Tanaka gulped while sweating nervously. "She picked from the box remember..."

"H-hai! She just unluckily picked the wrong punishment." Nishinoya shakily added, clinging to his friend. Suga-san is so scary!

"Well, what do we do? You can't play in... that."

"WHAT?!" Instantly, Karasuno's main setter, who were frozen just earlier, stomped towards them with an annoyed face.

"K-Kageyama!" she shrieked and hide behind Suga.

"BOKE! GO AHEAD AND TAKE THAT OFF NOW!"

"Wh-what? Kagayema, you pervert!"

"N-NO!" Kageyama flushed red, realizing his wrong choice of words while everyone gave him a look of pure shock. Except for Tsukishima, who is snickering. "I- I mean go somewhere! And change!"

"Hahaha... never knew you had it in you, King."

"Shut up you-"

"OI!" all of the Karasuno players almost jumped at Ukai's voice, who, after hearing what happened, suddenly looks livid. "Why are you all playing around, huh? We're here to practice, not play dares!"

"S-Sorry!" Hinata squawked, looking scared and ready to cry.

"But Ukai, our match is about to start..." Takeda-sensei informed the fuming coach. And true, while the Karasuno members are still dealing with the problem at hand, their opponents were already positioned on the other side of the net. It doesn't mean though that they're not staring. Actually, they're all staring so hard with reddened cheeks at their female player that Takeda-sensei is starting to get nervous.

As if he has a sixth sense, Sugawara turned to the Shinzen players and glared. "What are you all staring at?"

Instantly, the Shinzen team looked away, getting chills all around their body. That nice guy is so scary!

"Well, ehm... let's go and play as well..." Daichi decided, gesturing for his teammates to get on their position. He stopped in front of Hinata and gave her a pat on the shoulder and a sympathetic glance. "Sorry Hinata, looks like you'll not be playing for this game."

The girl pouted before nodding solemnly. As her teammates we're getting ready, she walked towards their two managers to join them. She sighed.

"Are you okay?" Yachi asked worriedly.

"Yeah, I'm fine. I lost so I have to do this punishment. No matter how embarassing this is." she voiced quietly. "But I'm dissappointed I can't play. I need to help the team."

Kiyoko hummed, assessing Hinata's appearance and then looks towards the game which is about to start. She noticed Kageyama looking at their direction, frowning as usual and even Tsukishima took a quick glance before staring ahead.

"It's not like you cannot support the team from the sideline." she stated, giving the middle blocker a smile.

"What do you mean Shimizu-senpai?"

"Well, a little cheer would help." the third year continued to smiled cheekily. "Especially from you."

"Oya, oya... this is interesting." The black-haired captain of the Nekoma team commented while watching the two teams playing the last match of the day. "Who knows that they have something like this planned huh? Those devious crows."

"It doesn't look like a plan." Kenma stated, brows furrowed while watching. At their side, Yamamoto is whimpering hopelessly, tears comically leaking from his eyes as Yaku scolds him to shut up. Lev, as usual, looked excited. "Hina-chan looks so cute! I'll ask her to cheer for me too!"

"Oh?" Kuroo turned towards his friend and grinned upon seeing his expression. "What's with that face? You looked so mad."

"Suga-san doesn't seem to like the idea, based on how he's scaring the other team right now." the Nekoma setter muttered, after giving Lev a look. "And I'm not mad."

"Well, if you say so."

Kuroo of course didn't believe his bestfriend on his denial. He smirked to himself as he watched his friend grew more and more irritated at the sight before him.

Suprisingly, the Karasuno team is leading the game even without the decoy playing for the team. Though it's almost the end of the day, the crows seems more energetic and focused than ever, including the orange-haired girl cheering at the background. Yes, that must be it.

He remembered from one of Yamamoto's useless squabble that a girl's cheer can give him the strength to win everything, even the Nationals. Given that it's the mohawk who's speaking, he tossed the comment aside and punished the guy with ten laps for being noisy.

However, looking at what's happening now, he wonders if it's true.

A loud thud was heard as the ball hit by Karasuno's baldy wing spiker bounced from the ground on the Shinzen's side of the court. In an instant, Tanaka's roar of victory was heard all over the gym, followed by a loud cheer from the sideline.

"Nice spike! You're so amazing, Tanaka-senpai!"

Kuroo saw the player's face immediately reflect pure delight at being called a senpai, especially by his cute kohai. "I know, right? Hahaha!"

"How about me, Shoyou?!" Nishinoya interjected with a hopeful face.

"Of course you're also amazing!" Hinata Shoyou praised, eyes starry and filled with awe, jumping up and down even with her skirt. "The way you dive for the ball is so gwaahhhh! And then it went up like zooommm! You're one of the best liberos in the world, Noya-senpai!"

As if struck by cupid's arrow, the libero stepped back clutching his chest, face red, and lips trembling. Beside Kuroo, Kenma's eyes narrowed, and it took him a lot of self-control to not burst out laughing.

A whistle was heard signalling the start of a serve from Karasuno's side, and everyone reverted back to their positions. Kageyama held the ball in his palm, and took a deep breath.

The ball was thrown up, followed by the rise of his body, and the moment ended with a service ace spiked on the other side of the court.

"Nice serve, Kageyama-kun!" his loud partner shouted. "You're really the coolest!"

"W-What are you saying b-boke?!" the setter's face defies description, not used to the praise being thrown his way.

"Damn it... this is so unfair!" someone cried from the Shinzen team, and the Nekoma captain pitied them a bit.

As it turns out unexpectedly (or not), Karasuno won their last match for the day, and it's all thanks to the maximum effort of the team, plus the cheerful support of their decoy. Everyone was praised, even Tsukishima (whose expression remained nonchalant but the tips of his ears red everytime he remembered the decoy calling him 'Tsuki').

While everyone is getting ready to end the day by tidying up the gym, Kuroo looked to his left and found his friend missing. Further search with his eyes lead him to seeing the pudding head approaching Karasuno's middle blocker, and he snickered. Oh, how he will tease him about this later.

Kenma, on the other hand, is oblivious to Kuroo's stare at his back, his attention focused solely on his girl friend picking some stray balls on the corner of the gym. For some reason, he was bothered by what his friend is wearing (not that he thinks she's not cute- hell, he actually almost had a heart attack the first time he saw her outfit). Hesitantly, he approached her, feeling wary of her teammates' curious glances.

"Shoyou."

Instantly, the girl spun around and beamed upon seeing him. "Kenma! What's up?"

The pudding head heard his heart skipped a bit, and tried to look anywhere but her face, but then just settled on looking at her face (looking anywhere in her body seems to be worse- he can see too much skin and it's enough to turn his face as red as his jacket). "W-why are you wearing something like that?"

"Oh... this." Hinata looked embarassed again. "I lost a bet."

"Oh."

"Yes. Hahaha..."

An awkward silence followed as Hinata just stared at her friend, who looks to be debating with himself about something.

"Uhmmm.. Kenma-oh?!"

"Here." As soon as Hinata started speaking, Kenma removed his jacket and handed it to the girl in front of him. "Wear it. I don't want you catching a cold."

"O-okay." She took the clothing from him and in the background, someone gave a faint shout of protest.

"Just return it to me tomorrow." he said, turning his back to her and walking away. He needs to get out of here, away from the prying eyes of everyone in the gym who saw his action. Honestly, he didn't know why he did it either. This is so unlike him.

Heading back towards his teammates, he heard the girl shouted his name and he turned around. His eyes widened.

There, all in her orange and red glory, stood the girl wearing the jacket. His jacket.Kenma is not a tall person but since the girl is shorter than him, his jacket seems bigger on her, hiding her upper body and half of her skirt when she zipped it up.

"Thank you! You're so sweet!"

Caught off guard, he didn't answer and instead, run away, out of the gym, face in flames.

Anyone who witnessed the boy dashed away stay silent and did not comment. Though several seconds later, someone guffawed loudly from the group of cats.

Poor Kenma. :-)

See you on the next one-shot!
