In the heart of a thriving valley, Yukumo Village stood as a haven where the steam of hot springs whispered through the air, carrying with it a sense of peace. Hunters from far and wide gathered here, whether to take on new missions from the guild or to find a moment of rest. Among the village's many homes, one particular two-story house nestled against the mountain's edge, its second-floor window adorned with red curtains that swayed gently in the morning breeze.

Inside, the first light of dawn crept into the room, revealing two figures resting in a cozy bed, wrapped in each other's warmth. The man's arm draped protectively over the woman beside him, his hold both firm and tender. As the room brightened, the golden hair of the woman, Naruko Uzumaki, shimmered in the light, her soft, whiskered cheeks hinting at her origins. Next to her lay Sasuke Uchiha, his dark hair tousled from sleep, his eyes already open as he quietly watched her.

Naruko stirred, her lips curving into a smile even before her eyes opened, sensing the familiar presence beside her. When she finally turned to face him, her brilliant blue eyes met his onyx gaze, and for a moment, they simply looked at each other, content in the silence of the early morning.

"Good morning," she whispered, her voice hushed and affectionate. Leaning in, she kissed him softly, their lips meeting in a gentle exchange that spoke of the bond they shared.

Sasuke returned the kiss, his hand sliding along her back as he deepened the connection for just a moment before they both pulled away. Naruko's smile widened as she teased, "Someone's eager this morning."

Sasuke's smirk was lazy but sincere as he leaned in closer, his breath warm against her ear. "How could I not be? Just looking at you makes my heart race."

Naruko felt a thrill run through her at the husky timbre of his voice. With a playful grin, she shifted her position, moving to straddle him. The blanket slid down, revealing her body—toned and beautiful, with curves that had only become more defined over the years. Her full breasts, crowned with soft pink nipples, swayed slightly as she settled on top of him, and Sasuke's eyes darkened with admiration and desire.

Three years ago, her body had been softer, being plump that made her all the more luscious in his eyes. Even now, toned and strong, she still retained the curves that drove him wild, her hips and thighs full, her ass round and perfect. He couldn't help but reach up to touch her, his hands trailing over the smooth skin of her thighs as he drank in the sight of her.

But just as the moment was about to escalate, a small voice called out from the hallway, "Mama! Papa!"

Naruko paused, a resigned but affectionate smile crossing her lips. "Time to check on the kids," she murmured, her voice a mix of amusement and maternal warmth.

Indeed, Naruko and Sasuke were parents to twins—a boy and a girl who filled their lives with love and chaos in equal measure. Sasuke let out a small groan, clearly frustrated at the interruption, but Naruko only giggled. Leaning down, her breasts brushing against his chest, she whispered, "It's okay. Tonight, I've got a surprise for you—something you won't see coming."

That sparked a grin on Sasuke's face, his frustration melting away. "You'd better keep your promise," he replied, a playful challenge in his tone.

With one last smile, Naruko slid off him and began to dress, her movements fluid and graceful. As she pulled on her clothes, Sasuke couldn't help but admire her all over again. He finally sighed and pushed himself out of bed, following her lead as they prepared to face the day. There would be plenty of time to continue where they left off later. For now, the world outside their door called to them—a world of monsters, hunts, and the life they had built together in this strange new land.

As Naruko and Sasuke stepped out of their bedroom, they walked down the hall to the room where their little bundles of joy awaited them. Opening the door, they saw Neoma and Menma Uzumaki, their twins, still snuggled in their beds. At three years old, the twins were a perfect blend of their parents: they had the blue eyes and whisker marks of their mother, Naruko, but the dark hair and skin tone of their father, Sasuke. Both twins were sleeping soundly, but the peace of the morning was interrupted by the soft cries of another child.

In the corner of the room was a crib, from which the cries emanated. Naruko quickly moved to pick up the baby girl, lifting her from the crib with gentle, soothing motions. The child had caramel skin, dark eyes, dark hair tipped with mint green—a unique combination that marked her as different. This was Kiko Uchiha Kimera, the daughter of Fu Kimera, the Nanabi Jinchuriki who had also been transported to this world by accident.

Naruko cradled Kiko against her chest, rocking her gently to calm her down. She whispered softly, "It's okay, little one. Fu will be back in a few days."

Naruko's thoughts drifted back to when she first met Fu. They had both arrived in this strange world by chance, both lost and alone. Over the months, they had grown close, their shared experiences and struggles forging a deep bond of friendship. A year later, during a celebration with friends from another world—people from a society where everyone had powers—things had taken an unexpected turn. After too many drinks, Naruko, Sasuke, and Fu had woken up together in bed, naked and confused about what had happened.

A few months after that night, Naruko discovered she was pregnant with Kiko. It was a surprise, but Naruko's relationship with Sasuke didn't change. Instead, they found a way to embrace the unexpected turn their lives had taken. Naruko realized through this experience that she was bisexual, a revelation that Fu shared as well. Fu confessed her feelings for both Naruko and Sasuke, admitting she had been afraid of what they might think.

Rather than letting this revelation drive a wedge between them, Naruko and Sasuke discussed the possibility of an open relationship. Naruko was willing to share Fu with Sasuke, and after some initial hesitation, Sasuke agreed. Naruko managed to spice things up in their relationship, and Sasuke found that he enjoyed the dynamic, growing to love Fu as well. Fu, with her exotic skin and shared experience of a difficult childhood, became Sasuke's second wife.

Naruko continued to soothe little Kiko, murmuring softly, "Fu will be back soon, sweet girl. She'll be so happy to see you." Kiko's crying slowed, her big dark eyes looking up at Naruko with a mixture of curiosity and calm.

Meanwhile, Sasuke attended to the twins, giving them soft kisses on their foreheads to rouse them. The twins awoke with sleepy smiles, their bright blue eyes lighting up as they looked up at their father.

"Are we going to see Uncle Izuku today?" Neoma asked eagerly, her eyes sparkling with excitement.

Sasuke chuckled softly, smiling at his children's enthusiasm. "Not today, but he'll be back soon with Uncle Katsuki and Auntie Ochako. They're on an expedition to a new land."

"Will there be new monsters and dragons?" Neoma asked, her eyes wide with wonder.

"There might be," Sasuke replied with a sigh and a smile.

Menma, his small chest puffed out in determination, chimed in, "I want to go hunt with you and Mama!"

Naruko, holding Kiko in her arms, laughed softly. "Maybe when you're older, Menma. For now, you have to stay here and help me with breakfast."

Though she smiled, there was a trace of unease in Naruko's eyes. Deep down, she wondered if they would ever find a way back to the Elemental Nations. As much as she loved this new life and the family they had built, she feared what it might mean for her children to grow up as hunters. She didn't want them to face the dangers that she and Sasuke had faced. Hunting was not just a job—it was a perilous path, one that could easily lead to death.

She still vividly remembered the first time she and Sasuke had fought an Elder Dragon—a Kirin. It had been her first hunt, her first armor, and it was a battle she would never forget. The fight had been brutal, pushing her to the limits of her endurance. Since then, she had faced many other Elder Dragons, each battle as fierce and unforgiving as the last. There was one encounter she barely survived, an experience that had left her with scars both physical and mental.

Pushing these thoughts aside, Naruko focused on the present. "Alright, you two," she said, addressing the twins, "go change your clothes and get ready for the day. I'll start breakfast."

The little Uchihas nodded eagerly, scrambling out of bed and running off to change. Naruko followed Sasuke downstairs, handing Kiko to him as she went to the kitchen. Sasuke cradled the baby girl carefully, watching his wife with admiration as she prepared to cook. Naruko reached into her pocket, using a small seal on her palm to access a pocket dimension, and pulled out various ingredients—large cuts of meat, eggs, and other supplies—laying them out on the counter.

As Naruko began preparing breakfast, they chatted about Izuku and the rest of his team. They had set out on an expedition to explore a new land, and Naruko couldn't help but worry about them.

"I just hope they're okay," she said, cracking an egg into a bowl. "There are so many new monsters out there, and some of them are strong enough to overpower even the best hunters."

"They'll be fine," Sasuke reassured her, rocking Kiko gently in his arms. "They have their quirks to protect them."

Naruko nodded, though her brow remained furrowed. "True, but there are monsters in this world that we don't even know about. They're unpredictable."

Sasuke sighed, understanding her concerns. "You need to have faith in them, Naruko. Izuku's smart and always analyzes every situation. He won't let anything happen to his team."

Naruko smiled softly, a teasing glint in her eyes. "Yeah, his muttering skills are top-notch."

They both laughed, their worries momentarily forgotten. Little Kiko, watching her parents with wide eyes, sucked on her fingers, a small smile forming on her face as she listened to the sound of their laughter. In that moment, surrounded by their family, Sasuke and Naruko found a small piece of peace amidst the uncertainties of this strange new world.

As Naruko and Sasuke began eating their breakfast, Naruko gently fed Kiko, the baby's chubby arms flailing excitedly as she opened her mouth for the mushy food. Naruko wiped a bit of food from Kiko's cheek, cooing at her and making silly faces to coax a smile. The baby girl giggled, her tiny face lighting up with joy. Sasuke couldn't help but smile at the scene, though his thoughts drifted to Fu. She was out in the field, studying monsters alongside Melissa Shield, a talented blacksmith.

Fu wasn't alone on her journey. Izuku Midoriya and the rest of their friends had joined her on a hunter fleet heading to explore a new world. Every day, they encountered new monsters to study and hunt, and Sasuke couldn't help but worry about their safety. As a hunter, he often donned his Anjanath or Tobi-Kadachi armor to enhance his lightning release, pairing it with a katana and arrows to take down the beasts they faced. Naruko, on the other hand, had an array of armors tailored for various elemental types. Some were quite...revealing, which Sasuke secretly found both distracting and advantageous, depending on the hunt.

A sudden knock on the door pulled Sasuke from his thoughts. He told Naruko he'd get it, rising from his chair and making his way to the entrance. Opening the door, he was met by a familiar face—Tayuya Uzumaki. Her red hair was unmistakable, and she greeted him with a teasing, "Hey, duck ass." Sasuke sighed, rolling his eyes at the nickname.

"Good to see you too, Tayuya," he replied, stepping aside to let her in.

Tayuya had once been one of Orochimaru's guards, but after surviving the destruction of the Sound Four, she had been accidentally transported to this world. The hunters had found her before they discovered Naruko and Sasuke, helping her heal and become one of their own. Tayuya had quickly risen through the ranks, becoming one of the best hunters among them. As an Uzumaki, she possessed the Adamantium Sealing Chains, a power she had first unleashed in a desperate battle against a Kirin, proving her lineage and formidable strength.

As Tayuya entered, Sasuke led her to the kitchen. Naruko, still feeding little Kiko, looked up and smiled. "Hey, Tayuya. What brings you here?"

Tayuya's expression was serious as she took a seat. "I've got news. The fleet that went to the New World ran into something big—Zorah Magdaros. One of the ships ended up on its back, and it was carrying Izuku, Katsuki, Ochako, Mei, Melissa, and Fu."

Naruko and Sasuke's eyes widened in shock. Naruko quickly handed Kiko to a shadow clone she summoned without hand signs, gesturing for Sasuke and Tayuya to follow her outside, away from the kids. Once outside, Naruko turned to Tayuya, concern etched on her face.

"Are they okay?" Naruko asked, her voice tense.

Tayuya nodded. "I got a message from Fu. They're all fine. They managed to set up a station on Zorah's back. It's called Astera. The Research Commission wants you and Sasuke to join them in the New World. Ruby and Oscar are arriving with another fleet to pick us up."

Naruko exchanged a worried glance with Sasuke. "Can we bring the kids?" she asked, her protective instincts kicking in.

Tayuya had already anticipated the question. "I've spoken with the Commission and the Guild. They're allowing the kids to come to Astera. There will be plenty of hunters and trustworthy people around to keep them safe."

Naruko and Sasuke shared a moment of silent communication, weighing their options. They both knew the dangers of this new world, but they also understood the importance of being together as a family.

Time Skip:

Naruko stood on the docks, clad in her Kirin armor, the bright blue and white hues contrasting sharply against her skin.

Sasuke, in his Anjanath armor, held Menma's hand while Naruko carried Kiko and held Neoma's hand. The baby girl, Kiko, nestled comfortably against Naruko's chest, her head resting on Naruko's breasts. Sasuke couldn't help but feel a pang of jealousy at the sight of his daughter finding comfort in his wife's embrace.

Naruko noticed Sasuke's stare and shot him a teasing smirk, knowing exactly what he was thinking. Sasuke glared back, though his lips twitched with amusement as Naruko stuck out her tongue at him playfully.

As they waited, they weren't alone. A large fleet ship arrived to pick them up, and two figures stood on the dock, waiting for them. One was a woman wearing Rathalos armor beneath a red cloak, her silver eyes shining with a strange power. She wielded a scythe, the first of its kind in the history of hunters. This was Ruby Rose, a hunter from another world called Remnant.

Beside her stood her husband, Oscar Pine, a simple farm boy who had also been transported to this world by accident.

He had met Ruby, and the two had become inseparable.

Ruby turned into a flurry of rose petals, speeding toward Naruko and wrapping her in a warm hug. "Naruko! It's so good to see you!" she exclaimed, cooing over little Kiko. The twins, Neoma and Menma, ran up to their "Aunt Ruby," hugging her tightly.

Oscar followed behind, holding their daughter, Summer Rose Pine. The little girl had white skin, freckles, curly hair with red tips, and her mother's silver eyes. Oscar greeted Sasuke with a smile. "Good to see you, Sasuke."

Ruby looked at the group, her excitement palpable. "Are you ready?" she asked, her eyes gleaming with anticipation.

Naruko let out a sigh, a mix of nerves and determination. "Let's go to the New World," she said.

With that, the group boarded the ship, ready to embark on a new adventure, the unknown awaiting them in the New World.
