Miss Invisible (Oikawa x Reader x Kise)- KNB And Haikyuu Crossover

1- Curiousity

It's your first day at Aoba Josai as a first year student. You transferred there because of family circumstances.

You left without saying a word since you know that your brother already left.

You arrived there just to see the school campus filled with students. It's a new beginning and a new environment. You also want to learn how to communicate with others.

You went to your classroom. Later, the bell rang and students go back to their classrooms. You walked past some students along the way, no one noticed you and for you, it's a normal thing.

The class started and nothing eventful happened. You read some books in class and didn't get scolded by it. At lunch, you were about to leave when you heard some gossips along the way.

"Hey, are you going to watch the practice match?"

"Ohh for the Boy's volleyball?"

"Yup!"

"Ehh, Oikawa-san is at it again?"

"Let's go! I want to see!"

The group passes by you, not realizing that you're there. You fell into deep thought. After hearing what they said, you got curious and want to see what this volleyball match is.

You went to the court and watch the match while blending into the crowd.

You watch the match and could feel the intensity of the match below, Yet your face remained expressionless but your eyes showed determination.

The Match ended with Aoba Josai winning.

Oikawa went to the locker room and change the clothes he used for practice into his uniform. He was wiping his sweat off as he opened the door to exit the locker room.

When he opened the door, he can't help but squirm out loud when he saw a female figure in front of him.

"Hello." You greeted indifferently. Oikawa was taken aback.

"H-how did you get here?" He asked. Of course, it's weird, ITS THE BOYS LOCKERS ROOM WE'RE TALKING ABOUT!!

You tilted your head a bit "From the main door."

This caused Oikawa's lips to twitch "Ehhh! Girls are not allowed in here!" He looked around "Did Iwa-chan let you in???"

You shook your head "I have a favor to ask."

Oikawa stared blankly at you "Favor?!" You nodded in response.

"Practice with me." You said in a simple manner. Like a thunderclap behind Oikawa, he stepped back.

"We didn't even know each other!" He responded. You looked at him indifferently "I'm [Y/N]. Your Oikawa, That's that."

This caused Oikawa to look at you weirdly and wanted to refute.

"So, you wanna help me?" You asked once more. Oikawa couldn't help but tremble in frustration. "Ahhh! I know I'm handsome but this is the first time someone threatens me just to win me over!"

"I'm not trying to win you over, I just need your help." You cleared what he said. Oikawa scratches his head "[Y/N]-chan, I know you want to ask me a favor, but, we don't know each other for too long! Even if you want to ask someone a favor, this is not a way to ask them!"

You looked at him expressionless "Then I'll look for Iwaizumi-san and tell him that you're flirting with girls in the locker room." You turned your back when he grabbed you by your shoulders.

"Ai, Ai! Wait! Okay, Okay! I change my mind!" He panicked. You replied, "Are you chanting, Oikawa-san?"

"I'll help you, but you can't restrict me in return!" You nodded in agreement. "I just need your help, I need to enter the girl's volleyball" You explained.

"How long do I need to help? Until try-outs?" He asked in curiosity. You nodded. He complained, "That's a month from now!" He added, "Ehhh, [Y/N]-chan, your cruel, your actually forcing me to be your servant for a month!" 

You stared at him blankly "I'm not forcing you." You paused "I'm just asking for a favor."

He remembered how you threatened him using Iwaizumi and couldn't help but shout in his heart 'YOU THREATENED ME JUST NOW!'

"Fine! I'll help you after practice." He accepted his fate of being threatened by someone he doesn't know. You nodded "Deal."
