The gymnasium reverberated with the sound of balls being spiked, players calling out plays, and the shuffle of feet on the polished floor. (Y/n) stood on the sidelines, her eyes scanning the court to observe her teammates in action. Their dedication and passion for the sport filled her with pride, knowing that each one of them was working tirelessly to become better players.

As she watched the practice unfold, her attention was drawn to Yamaguchi, who was stationed at the serving line. He seemed to be struggling with his jump float serve, his brows furrowed in frustration each time the ball failed to sail over the net smoothly.

(Y/n) knew that Yamaguchi had been putting in extra effort to perfect this particular serve. She also knew how much he valued her advice, considering her expertise in coaching. Making up her mind, she decided to approach him.

"Hey, Yamaguchi," (y/n) called out, making her way towards him. "Mind if I give you some pointers on your jump float serve?"

Yamaguchi's face brightened with surprise and gratitude. "Oh, (y/n)-san, that would be amazing! I've been struggling to get it right."

She flashed him an encouraging smile. "No worries! We'll work on it together. First, let's analyze your technique."

They spent the next few minutes breaking down Yamaguchi's serve. (Y/n) observed his footwork, arm swing, and toss, offering constructive feedback and suggestions for improvement. Yamaguchi absorbed her advice with great interest and tried to implement the changes right away.

"Keep your toss consistent and slightly in front of you," (y/n) advised as they practiced. "And remember to use your entire body to generate power, not just your arm."

Yamaguchi nodded earnestly, trying to internalize every piece of advice (y/n) gave him. As they practiced more, he gradually gained better control over the serve, and the ball sailed over the net with more accuracy.

"I can already feel the difference," Yamaguchi said, his eyes filled with excitement. "Thank you, (y/n)-san. Your guidance is invaluable."

"It's my pleasure," (y/n) replied with a warm smile. "I'm happy to help, Yamaguchi. Keep practicing, and you'll master it in no time!"

Emboldened by (y/n)'s support, Yamaguchi's confidence soared. He continued to practice his jump float serve with renewed determination, eager to showcase his progress to the rest of the team.

Later that evening, after practice, (y/n) found herself in a text message conversation with Tsukishima. She had knew that he had continued attending extra practices with his brother's team, and she was curious to know more.

Munchkin: Hey, String Bean, how's the extra practice with your brother going? 😊

String Bean: It's hard, I jammed my fingers whilst blocking today 😒

Munchkin: Ouch! That sounds painful. Did you tape them correctly? 😰

String Bean: Of course. No need to be so worried about me, Munchkin-san 😏

Munchkin: 🙄 I can't help but worry sometimes, especially when you're pushing yourself so hard. Just take care, okay?

String Bean: Haha, don't worry. I'm a tough one, remember?

Munchkin: You're the toughest String Bean I know, that's for sure 😄

String Bean: Thanks, I guess? 😂

Munchkin: No problem. You know I'm always here to support you, right?

String Bean: Yeah, I know. Thanks, (y/n)-san. I appreciate it.

Munchkin: Anytime, Tsukishima. So, apart from the jammed fingers, how are things going with the extra practices?

String Bean: It's been challenging, but I think it's helping. Their focus on blocking and receiving is different from ours at Karasuno. I'm trying to adapt and learn as much as I can.

Munchkin: That's great to hear! Different perspectives can be really valuable for your growth as a player.

String Bean: Yeah, I guess. But don't think I'm doing this just to impress you or anything.

Munchkin: 😂 Of course not. I know you're doing it to become a better player for your team.

String Bean: That's right. My main goal is to help Karasuno succeed, not to impress you or anyone else.

Munchkin: I never doubted that for a second, Tsukishima. Your dedication to the team is one of the things I admire about you.

String Bean: Munchkin-san, don't start getting all mushy on me. I won't be able to handle it.

Munchkin: Haha, don't worry. I'll save the mushy stuff for another day 😉

String Bean: Good. I'll hold you to that.

As their playful banter continued, (y/n) couldn't help but feel grateful for this lighthearted connection with Tsukishima. Despite his reserved nature, she knew that he trusted her enough to let his guard down and be himself.

As the days went by, Karasuno continued to immerse themselves in intense training sessions. The gymnasium became a crucible of sweat and determination, with each member of the team striving to improve their skills. Their hard work and perseverance were starting to pay off, and (y/n) couldn't be prouder of her players.

During the practice match against another team, the atmosphere was charged with excitement and nerves. The anticipation of putting their newfound skills to the test fueled the players' determination to give their best performance.

As the match unfolded, (y/n) observed the players closely, analyzing their strengths and areas that needed improvement. Tanaka, eager to demonstrate the success of his sharp angle spike, confidently approached the net. The set came, and with all his might, he swung his arm, aiming for that elusive sharp angle.

However, the ball hit the top of the net, falling back to their side. Tanaka's face flushed with frustration, and he let out a disappointed sigh.

"Augh! Sorry!" Tanaka called out, feeling responsible for the point loss.

Daichi and Asahi exchanged glances, acknowledging the challenge of executing such a difficult technique.

"Uh, did you see the angle on that cut shot?" Daichi questioned, incredulous. "It was so far out, it wasn't even funny."

"Yeah," Asahi agreed, his eyes wide with surprise.

The frustration on Tanaka's face was evident, and he grumbled, "Dammit!" under his breath.

Sensing his disappointment, (y/n) quickly went over to him, offering her support. "Hey, Tanaka-senpai, don't get discouraged. It's all part of the learning process. Keep trying, and you'll get it."

Tanaka looked up at (y/n), taking in her encouraging words. He knew she believed in him, and that gave him the motivation he needed. "Yeah, you're right," he replied, determination reignited. "I'll nail it next time!"

"That's the spirit!" (y/n) said with a reassuring smile. "Remember, every attempt brings you closer to success."

Encouraged by (y/n)'s words, Tanaka shook off his disappointment and refocused on the game. As the match continued, he made a conscious effort to apply the tips (y/n) had shared with him during their individual practice sessions.

With each new attempt, Tanaka's sharp angle spikes showed incremental improvements. Although not every shot hit the mark, his determination never wavered. His teammates rallied around him, offering constant support and cheering him on.

"I got it!" Tanaka exclaimed with delight, after a particularly successful sharp angle spike that left the opposing blockers dumbfounded.

"That's the Tanaka-senpai we know!" Hinata exclaimed, pumping his fist in the air.

Nishinoya chimed in, "Yeah, keep 'em coming, Ryuu!"

Seeing the joy and camaraderie among the team, (y/n) couldn't help but feel a deep sense of pride. Karasuno's spirit was unstoppable when they worked together and lifted each other up.

As the practice match concluded, (y/n) gathered the team for a brief huddle. "Great work, everyone! I'm proud of the progress you've all made. Remember, the journey to improvement is filled with challenges, but it's those challenges that shape us into better players. Let's continue to support and push each other to new heights!"

The team members nodded in agreement, their determination shining in their eyes. They knew that (y/n) believed in them, and that belief gave them the strength to conquer any obstacle that lay ahead.

As Karasuno continued to train hard, the gymnasium echoed with the sound of bouncing balls and the players' spirited shouts. (Y/n) couldn't help but feel proud of her teammates as she watched them push themselves to the limits. Each one was determined to improve, and their progress was evident in every move they made.

Kageyama and Hinata, in particular, had been working relentlessly on their new quick attack. The dynamic duo's ambition to perfect this move was infectious, and it motivated the rest of the team to work even harder.

During one practice session, (y/n) stood at the sidelines, observing Kageyama and Hinata closely. Their chemistry and synchronization were getting better with each attempt, but (y/n) knew that there was still room for improvement.

As they prepared for another round, (y/n) approached them, offering some guidance. "Remember to focus on your timing and communication, guys. Hinata, make sure your approach is precise, and Kageyama, trust your instincts and set at the perfect moment."

Kageyama nodded, taking in (y/n)'s advice. "Got it, (y/n)-san."

Hinata's determination was evident in his eyes as he replied, "We'll nail it this time!"

With renewed determination, the two positioned themselves on the court. The ball flew seamlessly between them, and Hinata launched into the air with astonishing speed. He swung his arm with precision, hitting the ball with all his might.

The ball soared over the net, the perfect set executed by Kageyama. The quick attack struck the floor on the opposing side with incredible force, leaving the other team in awe.

"Akright! Nice one, Hinata!" Kageyama praised, his face beaming with satisfaction.

"Your set was spot on, Kageyama!" Hinata exclaimed, his excitement contagious.

(Y/n) clapped her hands, applauding their effort. "That was amazing, you two! Your timing and synchronization were on point."

The rest of the team joined in, surrounding Kageyama and Hinata with congratulatory pats on the back. The atmosphere was charged with camaraderie, and the players knew that they were inching closer to mastering the quick attack.

The following day, the gymnasium was once again filled with the sounds of volleyball practice. As the team went through their drills and exercises, (y/n) noticed Yamaguchi practicing his jump float serve with even more determination. He was eager to showcase his improvement from the previous day.

(Y/n) approached him with a smile, "You've got this, Yamaguchi. Trust in your training and go for it!"

Yamaguchi nodded, taking a deep breath to steady his nerves. With focused determination, he stepped up to the service line. The gymnasium fell into a hushed silence, all eyes on Yamaguchi as he prepared for his serve.

In that moment, the world seemed to slow down for Yamaguchi. He tossed the ball into the air, his body moving in perfect harmony to execute the jump float serve. The ball left his hand, spinning with precision as it sailed over the net.

The tension in the gymnasium was palpable as the ball approached the receiving team. Nishinoya, known for his incredible receives, stepped forward to take the ball. But to everyone's surprise, the ball dipped and swerved in the air, making it difficult to predict its trajectory.

Nishinoya lunged forward, his lightning-fast reflexes at work, but the ball grazed his fingertips, sending it slightly off course. The ball hit the ground with a thud, and the gymnasium erupted into cheers and applause.

"You did it, Yamaguchi!" Tanaka yelled excitedly, giving him a high-five.

"That was insane!" Hinata exclaimed, his eyes wide with amazement.

(Y/n) clapped her hands, her heart swelling with pride for Yamaguchi's achievement. "That was incredible! Your jump float serve has become a real weapon, Yamaguchi."

Yamaguchi blushed, humbled by the praise. "Thank you, (y/n)-san. I couldn't have done it without your help."

Throughout the practice, Yamaguchi continued to show his progress with the jump float serve. With each successful serve, his confidence soared, and he embraced the role of a formidable server on the team.

As the practice came to an end, the team gathered around (y/n) for a debriefing. They were all tired but satisfied with the day's training.

"(Y/n)-san, thank you for all your guidance," Kageyama said as he bowed, a note of gratitude in his voice. "We're all improving because of you."

(Y/n) smiled at the team, feeling a sense of camaraderie that had grown stronger over time. "It's my pleasure to work with such a dedicated and talented team. You all have the potential to become incredible players."

"I agree!" Hinata chimed in, his eyes shining with determination. "And with you as our assistant coach, there's no limit to what we can achieve!"

The sentiment was shared by the entire team, and their united determination was evident as they looked towards the future with renewed vigor.

The journey of growth and improvement was ongoing, and (y/n) knew that each step taken by the Karasuno team brought them closer to their ultimate goal. She couldn't wait to see what the future held for them, and she was determined to continue supporting and inspiring her teammates every step of the way. With their hard work and dedication, she knew that they were bound for greatness.
