Throughout the week, (y/n) dedicated herself to working with the team, helping each member improve their receives and providing valuable guidance to Nishinoya, the team's libero. She offered her support and expertise, focusing on the smallest details that could make a significant difference in their performance. As the days passed, everyone showed remarkable progress and a newfound confidence.

Finally, the highly anticipated day of the practice match against Nekoma arrived, filling (y/n) with sheer excitement. The team had already departed to meet their opponents, leaving her with the task of preparing snacks and water to keep them fueled and hydrated throughout the intense game.

Venturing out to the local stores, (y/n) carefully selected an assortment of snacks that would satisfy the team's cravings while providing the necessary energy to sustain them during the match. She filled her basket with a variety of treats, considering each player's preferences and dietary needs.

As she strolled through the aisles, (y/n) couldn't help but reflect on the bonds she had formed with each member of the team. Their shared experiences, their laughter, and their determination to excel had created a sense of camaraderie that made her feel like an integral part of the team. She had grown not only as a player herself but also as a friend to each member.

With the snacks and water in tow, (y/n) headed to the gymnasium, her heart racing with anticipation. The bustling atmosphere filled with the sounds of bouncing volleyballs, echoing cheers, and the murmurs of excitement from both teams energized her even more. This was the culmination of their hard work and dedication.

...

Keishin and Naoi engaged in playful banter, exchanging jokes as the teams introduced themselves to one another. Their lighthearted exchange brought a smile to everyone's faces, setting a jovial atmosphere before the practice match commenced. Nekomata, ever the mischievous presence, couldn't resist adding his own snide remarks, provoking laughter from those around him.

"Oi, Ukai, I thought you said your little sister was going to be here?" Naoi teased, a mischievous glint in his eyes. "Man, I haven't seen her in seven or eight years, since that last match. All I remember is your grandfather getting her to practice her spikes. She spiked right into my gut."

A nostalgic smile crossed Naoi's face as he reminisced about the past, recalling the lively encounters they had during their previous matches. The memories of their spirited rivalry and intense battles were etched in their minds, and they held a special place in their hearts.

"Hehe, yeah, Jinx will be here soon," Keishin chuckled, fondly remembering his sister's nickname. "And she'll probably comment on how you're still as scary as she remembers, Naoi."

Naoi scoffed playfully, eager to defend himself. "I wasn't scary! She called you ugly!"

The playful banter continued, creating an atmosphere of camaraderie and friendly competition. The coaches exchanged jabs and jests, each remark met with laughter and good-natured ribbing. The past encounters had forged a unique bond between them, one that allowed them to engage in playful teasing without malice.

Amidst the laughter, Nekomata couldn't resist joining in on the fun, seizing the opportunity to make a witty remark. "You were both called ugly," he snickered, earning a collective chuckle from those around him.

As the lighthearted banter continued, the tension that often accompanied competitive matches dissolved, replaced by a sense of unity and mutual respect. Despite their fierce determination to win, the players recognized the value of friendship and camaraderie in their shared love for the sport.

With the teasing and laughter serving as a prelude, the teams were ready to showcase their skills and compete in a spirited and fair match. The jokes and memories of the past only fueled their competitive spirit, reminding them of the rich history they shared and the exciting future that awaited them on the court.

...

As the doors swung open, a rush of excitement filled the air, and (y/n) burst into the gymnasium. Her eyes immediately locked onto the familiar sight of the red jacket worn by her grandfather's old rival and friend, and without a moment's hesitation, she dashed toward him.

"Grandpa Neko!" (y/n) exclaimed, her voice filled with genuine joy as she leaped into his arms, wrapping him in a tight hug. The connection between them was rooted in a shared history and the deep bond between their families.

The old man, Nekomata, chuckled warmly as he embraced the energetic girl. "How's the Ukai spitfire doing? Look at you, all grown up and still carrying that same fiery attitude. Your grandfather would be proud."

After their embrace, (y/n) playfully released herself from Nekomata's grasp, a mischievous spark in her eyes. "Be prepared to lose, old man! I just got a call from gramps. He said it's my job to make snide remarks at you the entire time since he can't be here to do it himself."

Nekomata's laughter filled the room, his vibrant spirit lighting up the atmosphere. "Why am I not surprised? Of course, he'd make you do it. You're practically cut from the same cloth, (y/n)."

Grinning confidently, (y/n) didn't miss a beat, ready to engage in their friendly banter. "Yeah, well, I'm surprised you can still walk. Careful, old man, wouldn't want you to break a hip or anything. You're not as spry as you used to be."

Nekomata raised an eyebrow, a playful glimmer in his eyes. "Is that so? We'll see about that, spitfire. I may be older, but don't underestimate the tricks I've got up my sleeve."

Their exchange was a testament to the enduring camaraderie between their families, a legacy of fierce competition and mutual respect. The banter, though lighthearted, carried with it a deep understanding and affection that had been nurtured over the years. It was a reminder of the vibrant history that shaped their present, as well as the enduring friendships forged through their shared love for the sport.

As (y/n) continued to engage in her playful banter with the older Nekoma coach, the members of the Nekoma team approached the Karasuno team, their curiosity piqued by the presence of the spirited girl.

A tall boy with unruly bedhead couldn't help but voice his question. "So, who's the girl?" he asked, his eyes scanning (y/n) with interest.

Instantly, Nishinoya and Tanaka bristled with protectiveness, ready to defend their teammate. However, Daichi intervened, smacking them on the back of their heads to prevent any unnecessary tension.

"Oh, she's the coach's younger sister," Daichi explained, his tone calm and reassuring. "She grew up attending our matches during the fierce rivalry between our teams, so she's familiar with both your coaches."

(Y/n) couldn't help but involve the other Nekoma coach, "Naoi, you're still as intimidating as ever. I swear, you and my brother could pass as twisted twins or something," she remarked, a mischievous twinkle in her eyes.

"Hey! Show some respect!" Naoi retorted, his voice filled with mock offense.

Keishin, standing nearby, couldn't resist chiming in. "Called it," he declared with a chuckle, knowing all too well the dynamics between (y/n) and the other coaches.

Naoi directed his frustration at Keishin. "Shut up, Ukai! She insulted you too!" he exclaimed, his voice laced with playful annoyance.

Both teams observed the amusing spectacle of their coaches being playfully knocked down by (y/n)'s sharp wit. Laughter echoed through the gymnasium, bridging the gap between the rival teams and fostering a sense of camaraderie.

As the jovial atmosphere enveloped them, the Nekoma and Karasuno players couldn't help but exchange knowing glances and smiles. They were united by their shared love for the sport, and in that moment, the rivalry took a backseat to the celebration of their mutual respect and passion for volleyball.

With a playful smirk, (y/n) decided it was time to divert her attention from her brother and his old friend, focusing instead on the eager faces of her team. A radiant smile spread across her face as she approached them, her excitement palpable.

"You guys look great! Ready for the match?" she asked, her voice brimming with enthusiasm.

Bounding towards them, she cheerfully chirped about the upcoming match, receiving nods of affirmation from her teammates. Tsukishima, ever the stoic, stood by unimpressed, his arms crossed. Undeterred, (y/n) turned her attention to the Nekoma team.

"I'm Ukai (y/n), but you can all call me (y/n)," she introduced herself with a friendly demeanor.

Nekoma's tall captain couldn't resist playfully singing praises to her, his teasing tone laced with a hint of admiration. Leaning closer to her, he remarked, "Oho, who would've thought there'd be such a cutie related to the famous and terrifying Ukai?"

However, his playful banter was abruptly interrupted by a well-aimed smack on the back of his head. The tall teen recoiled, rubbing his sore head, and (y/n) turned to find a shorter boy with brown hair and eyes—the source of the interruption.

She couldn't help but notice the resemblance between him and Suga, a member of her own team. "I'm sorry about our captain. I'm Yaku Morisuke, and this is Kuroo Tetsurou," the boy introduced himself and his captain, extending a hand towards (y/n).

Smiling warmly, (y/n) shook Yaku's hand before shifting her attention to the remaining members of the Nekoma team. Kai, the third-year, exuded a sense of calm and tranquility. Inuoka, a bundle of energy reminiscent of Hinata, eagerly introduced himself, while Shibayama, more reserved, offered a timid greeting. Yamamoto, with his mohawk and expressive faces akin to Tanaka's, made his presence known, while Fukunaga remained quietly nodding.

Hinata, unable to contain his excitement, cried out to (y/n), "Hey, (y/n)-san! This here is Kenma! I met him the other day!"

Observing Kenma's discomfort with the attention, (y/n) simply smiled at him, offering a wordless reassurance. Her gaze then shifted back to the Nekoma team, her analytical mind taking over. Nekomata and the other coaches watched with amusement as (y/n) proceeded to unravel the composition of the Nekoma team.

"Alright, so Kuroo-senpai and Inuoka are your middle blockers, along with Yaku-senpai and Shibayama as your liberos. Kenma is clearly the setter, while Kai-senpai, Yamamoto-senpai, and Fukunaga-senpai take on the roles of wing spikers. And if I'm not mistaken, Yamamoto-senpai is your ace. Did I get that right, old man?" she concluded, turning to Nekomata, seeking his confirmation.

Snickering, Nekomata and Naoi nodded their heads, leaving their team dumbfounded. "How?!" Inuoka and Yamamoto exclaimed in disbelief.

"She's always been like this. Her knowledge of volleyball comes from watching and playing the sport since she was a toddler," Naoi explained, pride evident in his voice.

The Nekoma players stared at (y/n) in awe, some of them blushing at her display of expertise. Hinata, Nishinoya, and Tanaka couldn't help but push forward, huge grins plastered on their faces.

"That's our (y/n)-san! She's incredible, alright! You should see her play!" the trio exclaimed in unison, their excitement contagious.

The rest of the Karasuno boys nodded in agreement, sending warning glares at any Nekoma players who dared to linger their gaze on (y/n), particularly the scheming captain and the ever-blushing Yamamoto.

Finally, Keishin and the other coaches stepped in, diffusing the awkward stare-down and directing the teams to their respective sides of the court. (Y/n) joined Kiyoko on the bench, but not before adding a few playful jeers directed at Nekomata.

"Alright, let's get this practice match going! Let the Battle of the Garbage Dump begin!" she exclaimed with infectious excitement, her words resonating throughout the gymnasium, marking the start of a thrilling clash between the two rival teams.

The teams stood ready, their eyes locked on the court, eager to unleash their skills and determination. Yet, in the back of their minds, the echoes of their playful exchanges lingered, serving as a reminder of the bonds they had formed and the friendships that would endure beyond the final whistle.

With a shared nod and a newfound sense of camaraderie, both teams took their positions, ready to engage in a fierce and spirited battle. The court awaited, ready to witness their skills, teamwork, and unwavering passion for the sport. And as the match began, the echoes of laughter and camaraderie reverberated, reminding everyone that, in the end, it was not just about winning but also about the joy and shared experiences that volleyball brought into their lives.
