Yuki POV

Yuki silently laughed as she saw the two starting to get along. As soon as she saw the game he was playing, she knew Kenma would be a great friend for Shiro. As a bonus, she helped the boy find a friend.

Figuring she could leave them alone now, she focused back onto her book. She sighed as she tried to figure out the process the book was explaining. It was a book on how to program games. Due to her sister's immense love for any and all games, Yuki had a lot of knowledge on the good points and bad parts of different games, so she figured she should try to put the knowledge to good use and program one herself. She hadn't counted on it being so complicated.

Frustrated, she slammed her book closed and tapped her sister on the shoulder, interrupting her conversation with the black haired boy on their debate of the best FPS game. "Ne, I'm going to go back and get started on my homework. Remember we have to meet at the girl's volleyball gym after school today to get your application in."

"Hai. I remember." Shiro answered listlessly. "Go be the model student."

Yuki threw her sister an annoyed look before turning to her classmate. "I'm going back to the classroom, Kozume-san, but I'll leave you here since you seem to be having fun."

"Okay. I'll see you back in the classroom, Akumu-san." He answered.

With a smile at him and a poke to the cheek for her sister, Yuki turned and went back up the stairs to her classroom. She wanted to get her work done early so she had more time to practice after school. I gotta be able to keep up with her. I won't be the one to hold her back.

Time Skip (After school at the girl's volleyball court)

"Hey, Sakura-san." Yuki greeted lethargically. She had managed to finish all her assignments for the week (it was the first week after all) during her lunch break. "I brought her."

Not even looking up from her game, Shiro mumbled a half hearted greeting, "Yo."

Yuki rolled her eyes at her sister's rudeness. "Oi! Greet your elders properly."

Peridot eyes looked up and scanned the line of second and third years standing behind the pink haired captain. With a respectful bow, Shiro spouted out a proper greeting, "Hello senpais, my name is Akumu Shiro, position: ace. Pleased to meet you all."

A loud snort was heard in the back, "Ace? Please newbie like you shouldn't go around claiming to be the ace. Plus, you're not even that tall."

Emerald eyes rolled almost lazily in the direction of the speaker. Locking onto the red haired girl who had spoken, Yuki smirked, her stare intensifying, "Nani? Did you have something to say about my Imouto, bench warmer?"

There were visible shudders through the line of girls. Scary was the collective thought. The redhead especially looked ready to wet herself. "N-n-no! Of course not Akumu-san! Gomen!"

Emerald eyes shut in a fake cheery, closed eye smile, "That's what I thought. Anyway, yes, this is my little sister, Shiro. You can all call her by her first name so it doesn't get confusing. And, yes, she is my ace."

"Your ace?" One of the second years in the back asked. "Don't you mean our ace?"

Yuki shifted her gaze to the volleyball net hanging to her left. Her eyes had a far away look as she answered, "No, I meant my ace."

A silence bore down on the gym before the captain, Sakura Hiyoshi, spoke up, "O-okay everyone! Let's start! We'll start with some receives."

The girls scattered to their bags to get ready for their practice. Their coach had told them to assess the new first years themselves and get back to her. There were only three applicants this year; the girls' volleyball team wasn't nearly as popular as the boys' even at the middle school level.

"Begin!"

Yuki, one of the two designated servers, threw the ball into the air and smacked it toward the other side of the court. The brown haired first year attempted to receive it with an underhand, but the ball was going too fast and she ended up falling backwards.

"Chiyo-chan you need a firmer stance. Your feet weren't solid on the ground, so you couldn't handle the force of the ball." Yuki called out before hitting another.

Chiyo scrambled to get into position. She barely made it into a receive stance before the ball came flying. This time, however, she managed to hit the ball in the air.

"Good enough. Next!"

The sound of balls being hit sounded throughout the gym. Looking at the next person, she saw peridot eyes staring intensely at her from the other side of the net.

Yuki smirked and backed up. Stepping forward, she started to run, throwing the ball up simultaneously.

"Akumu-san! Wait! They can't handle your jump serves yet!" Sakura cried out from her spot watching at the side of the court. Unfortunately, it was too late. Yuki took a deep breath in and held it as she slammed her hand into the ball sending it rocketing to the other side of the net.

The ball veered a little towards the right, heading straight for the other line of girls who had been innocently practicing their receives with the other server. High pitched screams were heard before a white flash appeared out of nowhere.

The other girls stared in awe as the ball went flying in a perfect upward arc. Standing where the ball had been received was Shiro, a smug smirk on her face. Her eyes were glued to her elder sister who was smirking right back.

"All power, no control." Shiro stated simply. "Where were you even aiming at? Hana's head?"

Aforementioned girl squeaked at the thought of the fast ball hitting her in the head.

"Tch." The older white haired girl attempted to hide her embarrassment, biting back, "I was making sure your reaction time wasn't getting rusty with all that time you spend in your room."

"Pot. Kettle." Shiro responded, pointing at herself then her older sister.

"Whatever." Yuki grumbled. Picking up another ball, she shouted, "Next!"

After running through each girl five times, Sakura called for the team to start practicing spikes. The whole team seemed extra attentive to the new first year, especially after she had received one of their team's famous jump serve.

"You think she can spike as well as she receives?" A whisper was heard.

"No. I bet she's better off as a libero but wants the attention of being an ace."

The theories continued. Neither sister paid any attention. Instead, they were staring into each other's different shades of green eyes. From the outside, it looked like they were having a staring contest. To them, however, it was their form of communication.

'Do you want to show off or nah?' Yuki asked silently.

'What do you think?' Shiro responded with an eye roll.

'Well one can never be too sure with you.' Yuki rolled right back.

'What's that supposed to mean?' Shiro was met with silence as her sister broke eye contact to get ready to set.

"Begin!" Came the order.

The girls on the team took turns tossing the ball to their respective setters before running up to spike the ball. One by one they went. Some were well timed. The other two first years mis-timed and missed their spikes. Finally, it was Shiro's turn.
