Blood, mentions physical violence, normal teenage stuff y'know

The sound of volleyballs filled the air as the Aoba Johsai volleyball team practiced. Kentarō (who decided to show up for once) spiked down a ball between Kindaichi and Matsukawa that Yahaba set, it - of course - went out of bonds and towards the door that just opened. "Watch out!" Kindaichi yelled as whoever opened the door stepped out the way before the ball could touch him. The entire team stared at the stranger (who was staring at the ball that was rolling away), "Why the fuck are you here?" Kentarō walked towards you, "Mad Dog! Language in front of children!" Kentarō ignored Oikawa and stopped in front of said child. "Wow, not even going to ask what happened."

You looked like shit. There was blood from you nose that was carelessly wiped away smudged onto you lower lip, your hair was messier than usual, a black right eye, the undershirt you wear under your gakuran was dirty and untucked and your pants had rips in them. He didn't bother asking where the top part of your gakuran was. "Anyways, I got suspended and I need you to forge dad's signature." You held up a piece of paper. "What'd you do this time?" He took the pen you handed to him and forged the signature, "Beat up a kid." Not paying any attention to others in the room you took the pen and paper back. "You win?" You crossed your arms with a smug look on your face. "Hell yeah!"

A tiny smile came across his face that no one could see, "Good. Now leave." He pointed to the door before turning around, finally realizing that the entire team is watching. "Nah." You simply said as you sat on the bench and pulled your phone out. "What d'you mean no?" You could tell he was getting agitated and it was quite amusing. "Well dad's not gonna be happy if I just show up at home an hour early, and I have no where else to go. So," You looked at him with a 'you get the rest, bitch' face before looking back at your phone. Just as Kentarō was about to yell you Coach Irihata came in. "Oh, hello." Your hand was covering the lower half of your face, covering it from him view. "And who might you be?"

Quickly thinking, you put the 'Good Child' act on and quickly got up to bow, "Hello, Kyōtani (Y/N)!" If Kentarō wasn't pissed before, he definitely was now. "I'm just staying here to watch my big brother if that's okay!" Still in a bow (hoping he doesn't see your fucked up face) Coach Irihata ruffled your hair. "Of course you can! Just don't distract him too much, okay?" After promising not to make a distraction (your fingers were definitely crossed) to him, he left the gym. "Oh, wait! I got something for you!" Digging into your bag you threw your muddy - with only a small amount of blood on it - top at him, dirtying his practice shirt. "Oh, you bitch!" You cackled at Kentarō pissed off expression.

He threw your top at you, emitting a grossed out "Ew!" from you before you shoved it back in your bag. You flipped him off. "Mad Dog!" Oikawa ran up behind him, looking at you, "You didn't tell me you had a brother!" Oikawa crouched in front of you, getting way too close for comfort. You two held eye contact, "Wow, you were right." You looked at Kentarō, "He is ugly in person." Hearing Oikawa choke on air had you cackling again, Hanamaki and Matsukawa joining in. He walked away to complain to Iwazumi while Yahaba just face palmed and the first years looked confused (and frightened that a child younger than them came into the gym looking like a mess).

You looked at the two laughing meme lords of the team and they looked back, no longer laughing. "Is your hair fuckin' pink?" Matsukawa was on the floor clutching his stomach for dear life while Hanamaki was about ready to kill a child. "How old are you?" He cracked his knuckles, "14."
