"Um, so," Shouyo Hinata trailed off sheepishly before plastering a smile on his face and finishing his nervous speech, "that's why Natsu has to stay with me after school from now on."

"Ah," Daichi began as he gathered his thoughts while staring at the orange locks of hair almost hidden behind Hinata's right leg. "Hinata-"

Suga cut in. "It's nice to meet you, Natsu-chan." He crouched down on his knees so he could be eye-level with the half-hidden, slightly glaring girl. "I hope we can be great friends," he said, smiling.

Natsu Hinata continued giving untrusting looks to the gathered team from behind her brother. Only when Hinata placed a hand on her head did she move, ducking away from the hand to position herself on the other side of his legs but ending with an accepting nod towards Suga, though the politeness was awkward. Hinata treated his abandoned hand like it was normal, not even bothering to take his eyes from his senpais.

"She's being shy right now," he offered.

Daichi sighed as he looked at the two. "Hinata, there really is no one else? No trustworthy neighbors?"

Hinata brought his fists up to his sides. "Not a one, captain! Otherwise, I would have left her with them; Natsu doesn't even like volleyball," over-reaction gasps could be heard from Nishinoya and Tanaka, "so I wouldn't want her to be bored or anything, but there's no one to watch her until I get home, and practice can run late."

Suga lifted a hand to rub his neck. "That's true..." He looked to Daichi.

Hinata nodded vigorously, body still keyed up to argue his point. "And Mom doesn't want to leave Natsu alone at the house anymore; she's starting night shift at her job again."

The team hummed in sympathy.

Daichi closed his eyes in thought. "...I suppose...if there is no one else. She can stay afterhours with the rest of us." He continued, cutting off Hinata's yell of triumph, "But she must always be accompanied by you, Hinata; take your responsibilities seriously, no handing her off to another teammate to watch."

"Yes, captain!"

"And you must leave practice at 7 o'clock or before. Children like her need their sleep and shouldn't stay out long."

"Yes, captain!"

"And make sure she is well-fed before she gets here or has snacks that she can eat during practice; no reason for her to get hungry while she's here."

"Yes, captain!"

"And she should probably have something to play with to keep her occupied-"

Asahi leaned over to Suga and whispered, "Daichi-san seems more concerned for Natsu-chan than Hinata is."

Suga stiffled a laugh.

Tanaka, who heard their exchange, interrupted Daichi's monologue. "Geeze, captain, you'd think she was your sister, and not Hinata-kun's."

Daichi paused to give Tanaka a quieting look. He turned back to Hinata. "Got it, Hinata?"

"Yes, captain! I -we- won't let you down!" he said with a grin as he placed a hand on Natsu's shoulder, giving it a loving squeeze. "Natsu's a good kid, she won't cause any trouble."

"Yes, all you have to worry about is the team getting sidetracked and trying to play with her instead of practicing," Ukai commented as he stepped into the gym, having finished drinking his soda (instead of a good can of beer) outside of the gym.

Hinata responded to this by chuckling sheepishly while his sister switched her untrusting look/pout to the newcomer.

Suga smiled at the coach. "I'm sure Daichi can handle any waning attention."

"M- Yes, of course," said individual assured.

Ukai nodded. "Good to hear. On that note, let's get practice started."

"Yes!" chorused the team. They scattered to either take places on the court or to go to the locker room to change into uniforms.

Hinata lead his sister over to the spectator bench. He bent down to her eye level. "Okay, onii-chan's gonna practice for a little while. Cheer me on, okay, Natsu?"

She puffed out a cheek. "If nii-chan stops speaking to me like a baby, I might cheer for you instead of the other side."

"Wha-! Natsu, you'd root for the opposing team?"

She giggled at the look on his face. "Maybe."

"What about me!"

"I'll think about it."

"You should always cheer for your brother, you know."

"Nii-chan shouldn't tell me how to be a sister."

Hinata sighed, giving up.

Tanaka laughed in the background, Karasuno colors already displayed on his jersey. "I like her, Hinata. She acts like a miniaturized Tsukki!"

"Who acts like me?" said person asked as he and the other first years made their way to the locker room. He studied both siblings as he passed. He walked on, not bothering to ask about the situation. Yamaguchi followed in his wake.

Kageyama stopped in front of them. "Hinata, who is...?"

"Oh," Hinata perked up at his friend/rival, "this is my little sister, Natsu. We don't have anyone to watch her after school, so she's gonna hang out here with us during practice from now on." He smiled.

Kageyama studied them and shrugged. "Fine by me," he walked past.

Hinata turned back to his sister. "See, Nat-chan? Everyone loves you already!"

Natsu dodged the head pat with expert skill. "Nii-chan, don't you need to change?"

"Uh-"

"Hey, future ace, you still need to change, or have you forgotten your uniform like you do test answers?"

Hinata rushed to the changing room. "You are just as bad as me! Pan calling stove!"

"It's pan calling pot!"

Yamaguchi raised an eyebrow beside Tsukishima. "The saying is 'pot calling kettle'."

Tsukki sighed at the stupidity of his fellow first years. "Idiots."
