Haikyuu Fun-Shots

Gender Issues

An au where the first years are one day accidentally changed into the opposite gender.😱

Hinata stretched as he woke up from his slumber. He looked around the room seeing the other first years still asleep, he being the first up.

Hinata got up from his spot by the couches to go wake the others up to make breakfast.

Only to find-

"Ahhhhh!!!" Hinata screamed as he saw something on his chest. He groped his chest feeling, boobs.

Tsukishima and Yachi both rose from their spots, rubbing the grogginess from their eyes.

"What are you screaming about dumbass?" Tsukishima said as he reached for his glasses.

He put his glasses on only for his eyes to widen also. He saw that Hinata was no longer a boy but rather, a girl. He looked down at himself to find that he too was in the same state as Hinata-a girl.

He shakily put his hands on his chest, repeating the same actions as Hinata also finding mounds on his chest as well.

Yachi pulled her blankets away from her to find she was missing what both and Ysukishima and Hinata had, and had grown something else instead.

Yachi let out a scream in surprise waking up Kageyama and Yamaguchi.

"What the fu-" Kageyama was cut off by the scene in front of him. He glanced around the room to find that Tsukishima, Hinata, and Yachi were the opposite gender.

"What happened to us!!" Yamaguchi and Yachi both said in sync.

"Alright someone better fucking spill, this is a prank right?Right?!" Tsukishima said in slight  panic.

"Guys let's just calm down, maybe we can ask Sugawara-senpai or Daichi-senpai for help." Yamaguchi said to the group.

"If you haven't noticed YA-MA-GU-CHI we aren't exactly the same gender anymore!" Tsukishima exclaimed sarcastically.

"Let's just deal with it for now till we can solve this problem, because you're not the ONLY one stuck this way!" Kagayema yelled to Tsukishima.

"Let's just hurry and get this problem solved!" Hinata yelled.

All the first years nodded in agreement before getting ready in their newfound genders, and heading to the gym to address their problem to Daichi and Sugawara.

~Time skip to gym~

As they entered the gym, Tanaka and Noya ran up to both Tsukishima and Yamaguchi grabbing their hands with star struck eyes.

"And who might you beauties be?~" Tanaka and Noya said in unison.

"Eww, what the fuck, that's gay!"
Tsukishima scoffed before roughly releasing her hand from Noya's death grip and grabbing Yamaguchi by the wrist away from the duo.

"It turns me on when they do that!" Tanaka said hugging himself tightly.

"That's Tsukishima and Yamaguchi, Noya-senpai, Tanaka-senpai." Yachi explained making their eyes grow wide to the size of saucers.

"Who the hell are you pretty boy?!" Tanaka yelled as he gave Yachi a menacing glare, making him cower behind Kageyama and Hinata.

"Haaah?!" The team yelled.

"Then-" Tanaka started
"Hinata?! Kageyama?! What the hell happened?" Noya finished.

The team crowded the first years waiting for their explanation.

"Well all we remember is having a sleepover at Kageyama's house, we watched movies, ate cake and that's about it." Hinata explained.

"Now that you mention it Shrimpy, that cake tasted pretty weird, what was in it?" Tsukishima questioned.

"Well Yamaguchi helped me bake It, but I remember we put eggs, flour, sugar, milk, and just normal things you put in cake." Hinata said cupping her chin with her fingers.

"Did you put something extra?!" Kageyama exclaimed making Hinata think harder.

"Well I remember putting some extra flavoring into it to get a strawberry sort of taste. But I remember Yamaguchi said not to touch that cause it does something?" Hinata said in confusion.

Tsukishima clenched her fists in anger, shaking slightly. Yamaguchi and Yachi flinched with Tsukishima's sudden rage.

"Did that EXTRA flavoring say gender bent serum on it?!" Tsukishima seethed.

"Yeah, I think it did! Why?" Hinata asked.

"HINATA BOKEEEE!!!" Kageyama yelled. Asahi grabbed her holdong her back from launching herself at Hinata.

"Hinata-" Tsukishima said in a deadly calm voice, " That SERUM is mine and Yamaguchi's science project to change the SEX of a person!!" Tsukishima yelled before lunging at Hinata in an attempt to choke him.

Daichi caught her before she could reach, restraining Tsukishima from murdering Hinata.

"Let's calm down guys!" Sugawara said in an attempt to ease the situation, "At least he didn't change you guys into an animal or something right? Hahaha!" Sugawara said sweat dropping at the scene.

"How much of the serum did you put Hinata?!" Yamaguchi asked.

"Oh! Half the bottle!" Hinata said cheerfully.

This stirred Tsukishima up more causing her to struggle more in Daichi's grip. Kagayema had also tried to wriggle herself out to get to Hinata but Asahi kept a firm grip on Kageyama,  holding the two back from going at Hinata's throats.

"How long does the affects last?" Yachi asked in a rather deep voice shocking Tanaka and Noya.

"Well seeing as it is half the bottle, about 24 hours at the most." Yamaguchi explained.

Tsukishima and Kageyama sighed. "Well guess I just got to deal with it for now." Tsukishima said exasperated as she pinched the bridge of her nose.

The first years had spent the day with their new genders, but not without being catcalled or being humiliated in their new gender from the hormonal boys ogling at the beautiful "girls". (Mostly Yamaguchi and Kageyama, Tsukishima glared at people and Hinata just smiled with a blush; Yachi wasn't bothered as much).

As night fell they went back to Kageyama's home, and luckily without being questioned (or having to use the bathrooms), locked themselves in his room, waiting out the effects. Throughout the day Yamaguchi had kept a timer on to keep track of the serum.

"Yamaguchi how much more time?" Tsukishima asked rather irritated of being a girl for a full 24 hours.

"Let's see, couple more minutes! Then we will be back to normal!"  Yamaguchi said excitedly.

"It was actually fun today! We should do it again sometime!" Hinata said with a big smile.

"NO!!" the geoup yelled at her in unison causing her to flinch.

  Suddenly huge puffs of clouds appeared around their bodies clouding their vision. They fanned away the clouds inhaling some of it, when finally it cleared away, revealing their original genders, having the first years sigh in relief.

"Just so you know Hinata Boke, if you try that again, I'll have your throat as a souvenir!" Kageyama said giving Hinata a death glare and letting the first years out of his house. Hinata was left shuddering at the comment and his newfound lesson with baking and serums.
