The final night of the training camp had finally arrived, and the girls couldn't contain their excitement for the much-anticipated sleepover party. From the moment they had set foot in the camp, (y/n) and the managers had been eagerly looking forward to this special night of bonding and fun.

Throughout the day, (y/n) had been busy working with the teams, fully immersed in the intense training sessions. Meanwhile, the girls had coordinated their efforts to prepare dinner ahead of time, ensuring that they could fully enjoy their evening without any distractions. The kitchen became their designated space, strictly off-limits to the boys.

Just as the girls were busy preparing their dinner, Keishin made an unsuspecting attempt to enter the kitchen, hoping to borrow some sauce. However, he was met with a hilarious surprise. With lightning-fast reflexes, (y/n) grabbed the faucet spray and playfully doused him, causing him to yelp in surprise.

"Dammit, Jinx!" Keishin exclaimed, his wet hair clinging to his forehead as he hurriedly retreated from the kitchen.

A burst of laughter erupted from (y/n) and the girls, their gleeful amusement filling the air. It was a moment of lightheartedness amidst the intensity of the training camp, a playful reminder of their camaraderie.

Returning to their culinary mission, the girls continued with their pizza preparations. Each of them had chosen their favorite toppings, eager to create a delectable masterpiece. Shirofuku, renowned for her insatiable appetite, took the lead, determined to make not just one, but three different types of pizzas to satisfy her cravings.

With skillful hands, they spread the pizza dough, carefully arranging their chosen toppings, and placing the creations into the preheated oven. The tantalizing aroma of melting cheese, fresh vegetables, and savory meats filled the kitchen, teasing their taste buds and heightening their anticipation.

"Let's go prepare our room now!" Yachi exclaimed, her eyes sparkling with excitement.

"Our room?" (y/n) questioned, intrigued by the blonde's enthusiasm.

"Yes! We've planned something special to make this sleepover even more memorable," Kiyoko chimed in, her smile radiating warmth.

"Trust us, you're going to love it," Miyanoshita added, a mischievous glint in her eyes.

The group made their way to the room they had been sharing throughout the training camp. Usually, they slept on separate mats with sleeping bags, but tonight was going to be different—a night of creativity and coziness.

As (y/n) entered the room, she was met with a delightful sight—a large pile of pillows, blankets, plushies, and two tents.

"What's all this?" (y/n) asked, her curiosity piqued as she surveyed the assortment of items.

"We're going to transform our space into an indoor sleeping camp!" Yachi exclaimed, her voice filled with enthusiasm as she grabbed (y/n)'s hand and led her toward the pile.

With excitement and laughter filling the room, (y/n) and the girls set to work, creating their unique sleeping camp experience. They carefully set up the two tents in a large circle, arranging them so that their entrances faced each other. It was decided that Kiyoko, Yachi, and (y/n) would share one tent, while the other tent would be occupied by the remaining girls.

As they arranged their mats and sleeping bags inside the tents, a sense of anticipation filled the air. (Y/n) couldn't help but feel a warm sense of togetherness as they worked together, transforming the room into their cozy sanctuary.

Once the tents were set up, the girls focused their attention on the inner circle. They created a comfortable gathering space using an array of pillows and blankets. The room was adorned with soft cushions and fluffy throws, creating a haven of relaxation and comfort.

"(Y/n)-san, you get to sleep in the middle," Yachi declared, her eyes sparkling mischievously.

"Of course, you're the center of our attention tonight!" Kiyoko added with a warm smile.

The sudden ringing sound from (y/n)'s phone signaled that the pizzas were done, perfectly timed to coincide with the completion of their cozy indoor camp. The room was a kaleidoscope of vibrant colors, with soft blankets, plush pillows, and twinkling fairy lights creating an enchanting atmosphere. (Y/n) couldn't help but feel a surge of excitement as she looked around the inviting space, eager to dive into the fun-filled night ahead.

As they gathered around the table to enjoy their pizza, the girls decided that sharing embarrassing stories about their teams would be the perfect topic of conversation. To (y/n)'s surprise, Kiyoko had a treasure trove of amusing anecdotes from the senpais' early years at Karasuno. Her stories had everyone in stitches, and the room echoed with laughter and joy.

Even more hilarity ensued when Kiyoko shared a story from this year, before (y/n) joined the club. It turned out that Hinata, in a bout of nervousness before his first practice match against Seijoh, had accidentally put on Tanaka's pants instead of his own. The mishap led to Tanaka running out of the club room in his underwear, much to the amusement of onlookers. The image was so comical that (y/n) struggled to eat amidst fits of laughter, tears welling up in her eyes.

Eventually, they managed to finish their delicious meal, satiated and content. (Y/n) couldn't imagine eating another bite until Shirofuku spoke up, her voice filled with excitement.

"I've brought food coloring and flavors," Shirofuku announced, a mischievous glint in her eyes. "How about we make colorful flavored popcorn?"

The suggestion instantly ignited (y/n)'s taste buds, and her eyes lit up with anticipation. The mere thought of colorful, flavorful popcorn was enough to make her mouth water, mirroring Shirofuku's enthusiasm.

"That sounds amazing!" (y/n) exclaimed, unable to contain her excitement.

"It does sound tasty," Otaki agreed. "But how do we make it?"

Shirofuku, ever the expert, eagerly explained the simple process. "We just make regular popcorn, then we add sugar into a pan with the coloring and flavor of our choice. Let it boil, pour it over the popcorn, mix it, and voila!"

The girls quickly gathered an assortment of containers, knowing that one type of popcorn wouldn't be enough to satisfy their cravings. Working together, they transformed the plain popcorn into a delightful array of colors and flavors, creating a rainbow of deliciousness.

They had white popcorn with a hint of vanilla flavor, light brown popcorn with a caramel twist, pink popcorn infused with cotton candy sweetness, and light red popcorn bursting with the taste of ripe strawberries. The choices seemed endless as they experimented with red cherry-flavored popcorn, light green apple-flavored popcorn, and sunny yellow lemon-flavored popcorn.

Not wanting to leave out any delightful hues, they also created light blue bubble gum-flavored popcorn, light orange watermelon-flavored popcorn, and even black Oreo-flavored popcorn. The options were as imaginative as their laughter-filled evening.

To complement their rainbow popcorn, they gathered a myriad of other snacks and drinks, creating a feast fit for a sleepover party. They carried the bounty back to their cozy camp, settling down amidst the sea of pillows and blankets, their faces illuminated with anticipation and joy.

The rest of the night promised more than just snacking and talking, as Suzumeda had brought along a plethora of hair ties, hairstyling tools, face masks, and nail polish. The girls gathered in a circle, their backs facing each other, and excitedly began experimenting with different hair styles on one another. Laughter filled the air as they braided, twisted, and pinned their hair into whimsical creations.

Once the hair-styling extravaganza was complete, they moved on to applying brightly colored face masks, giggling at the sight of their transformed appearances. The room became a kaleidoscope of colors as they discussed their desired nail polish shades. That's when (y/n) had a mischievous idea that would make the game even more entertaining.

"How about we play spin the nail polish?" (y/n) proposed with a mischievous grin. "Just picking a color seems a bit boring."

The girls looked at (y/n) curiously, intrigued by her suggestion.

"Spin the nail polish? What do you mean?" Yachi asked, her eyes sparkling with curiosity.

With a flourish, (y/n) selected a bright fuchsia pink nail polish and placed it in the center of their circle, laying it horizontally.

"Alright, here's how it works," (y/n) explained, her voice brimming with excitement. "We spin the nail polish, and whoever it lands on has to paint one nail in that color. We keep spinning and painting until everyone's nails are done!"

The girls burst into laughter, charmed by the idea of this whimsical game. Kiyoko chuckled and nodded in agreement.

"Well, that will certainly give us some ridiculous-looking nails," Kiyoko remarked, her eyes sparkling with amusement. "But I'm in!"

And so, the "spin the nail polish" game began, with each spin determining the fate of their nails. As the rounds progressed, the girls ended up with an array of vibrant and unconventional nail colors. Their nails mirrored the exuberance of their laughter and the joy of their friendship.

In addition to their colorful nails, they adorned themselves with quirky hairstyles and the remnants of face masks. As they admired their transformed appearances, Miyanoshita suggested capturing the moment through photographs.

"Let's take some pictures together!" Miyanoshita suggested, her eyes gleaming with mischief.

"But only if we promise not to put them online!" (y/n) quickly added, laughing at the thought of their ridiculous snapshots circulating on social media.

The room filled with laughter as they struck silly poses and immortalized their unique looks in a series of photos. Each image captured their joyful spirit and the memories they were creating.

"I look awful!" Yachi exclaimed, inspecting her photo with a mix of horror and amusement.

"No way!" (y/n) vehemently disagreed, her eyes filled with warmth. "You look super cute like this!"

Yachi, however, seemed to be spiraling into self-doubt, unable to accept the compliments. (Y/n) realized that a more direct approach was needed to snap her out of it. In a playful gesture, (y/n) grabbed a nearby pillow and playfully tossed it at Yachi, who quickly retaliated. The friendly pillow fight escalated into a wild frenzy, with pillows flying and laughter echoing through the room.

When exhaustion finally settled in, they settled into their tents, nestling themselves in their cozy sleeping bags. The night was far from over, as they chatted and whispered in the darkness, sharing secrets, dreams, and aspirations.

"I'm glad we got to spend the evening like this," Yachi confessed, her voice filled with genuine warmth.

"Agreed, the boys have been monopolizing your attention, (y/n)-san," Kiyoko chimed in, her voice gentle and teasing.

The comment left (y/n) blushing and speechless, causing the other girls to giggle mischievously at her adorable reaction.

"This was really fun," (y/n) finally spoke up, her voice filled with enthusiasm. "We should definitely do this again soon!"

The girls nodded in agreement, feeling a deeper bond formed during this memorable night. They realized that these moments of laughter, silliness, and shared experiences were just as important as the rigorous training and matches they faced on the volleyball court. They cherished the sense of belonging and camaraderie that had grown among them, knowing that their friendship would endure long after the training camp concluded.
