Chapter 1

A.N. This is a long story and I have written many chapters for it. This story was divided into four before, now I am reposting it into one whole story. 

---------------------------------------

The Fourth Ninja War was a cataclysmic event that left an indelible mark on the entire world. It was a tragedy that no one wished to witness in their lifetime, yet reality is merciless, allowing the pieces of history to fall into place without concern for human desires. The war became the catalyst for a new era—one marked by unity and hope, but also haunted by the shadows of loss and devastation.

The war devastated the world, both physically and emotionally. Millions perished as the roots of the Shinju ravaged the lands, leaving infrastructure in ruins. Villages, once thriving, lay in desolation, and it took years of painstaking effort to restore what had been lost. The war was a stark reminder of humanity's fragility, of the frail line separating the ordinary from the extraordinary. For those who lacked chakra, the power wielded by ninjas became a source of both fear and resentment, fueling division and hatred.

Yet, out of the ashes of despair rose a new hope: Uzumaki Naruto, hailed as the Hero of Mankind. The records of the war were not hidden; every moment, every sacrifice was documented and shared with the world. It was an unflinching attempt to confront the truth and ensure that future generations understood the cost of war.

Naruto himself bore the weight of these revelations. For the first time, he felt the crushing enormity of his perceived failures as countless lives were lost in the chaos. Though many refused to place blame on him, radicals and dissenters voiced their discontent. But Naruto did not let despair consume him. Instead, he resolved to transform his pain into strength, determined to learn what it truly meant to lead.

Driven by his promise to Nagato and the teachings of his master, Jiraiya, Naruto embarked on a journey across the world. He sought to see the truth with his own eyes, to understand the struggles of others firsthand, and to ensure that no one could deceive him with false information. His journey was fraught with hardship, yet he pressed on with the support of his friends, never compromising his principles. Even when the path seemed cruel, Naruto stood firm in his resolve to prevent inhumane acts, regardless of the ends they claimed to justify.

At the age of 19, Naruto became the Sixth Hokage, using this position to develop his leadership skills and prove his dedication to his people. However, his time as Hokage was brief. Recognizing the larger mission that lay ahead, he passed the mantle to Kakashi and stepped into a role of even greater responsibility: the Emperor of Mankind.

This transformation was not a simple choice but the culmination of years of sacrifice and self-reflection. Naruto understood that to create a utopia, he could not ignore his own humanity. He embraced his desires, recognizing that selflessness did not mean suppressing who he was. To purify his soul and ensure his leadership was beyond reproach, Naruto created a technique called All The World's Good—a reality-altering jutsu that allowed him to purge all negativity within himself. It left him as a beacon of light for humanity, immune to corruption and despair.

As Emperor, Naruto enacted sweeping reforms. For those who had strayed but could still be saved, he instituted a policy of re-education, offering them a chance at redemption. However, for those who had crossed the line into unforgivable cruelty, swift and painless justice was delivered. His rule, while firm, was compassionate, always prioritizing the greater good.

The world, too, transformed under his leadership. Nations shared knowledge and advanced technologically, united by a common purpose rather than divided by rivalry. Naruto harnessed natural energy from the solar system to amplify the planet's reserves, leading to mutations that enhanced human abilities. Though this brought new challenges, it was a necessary step to prepare humanity for the looming threat of the Otsutsuki.

The Fourth Ninja War may have shattered the world, but it also set the stage for a brighter future. Through his sacrifices and unyielding determination, Naruto not only rebuilt a broken world but also led it into a new age of peace and strength. He became more than a hero—he became the Emperor of Mankind, a symbol of hope for all generations to come.

On their journey across dimensions, Naruto and his allies uncovered unsettling truths about the Otsutsuki clan. Kaguya, the once-feared goddess, was not the strongest of her kind—far from it. She was merely one among many, and their clan, scattered across the cosmos, wielded power that dwarfed even hers. Worse still, they were not oblivious to Earth. It was only a matter of time before they turned their gaze to the world Naruto had fought so hard to protect.

The gravity of this revelation forced humanity to confront its fragility. The ninja world, despite its remarkable strength, could not afford complacency. Naruto, who had surpassed Kaguya in power after the war, spearheaded efforts to prepare for the inevitable. His unmatched strength was bolstered by a formidable coalition of allies: Sasuke, whose revival cemented his role as Naruto's eternal rival and partner; Hinata, who attained the Tenseigan through the legacy of Hamura, the Sage's brother; and Toneri, who shared her celestial power. Alongside them were countless other comrades who had pushed their abilities to unfathomable levels.

Yet, despite their newfound strength, the knowledge that Kaguya was only a minor figure in the Otsutsuki hierarchy left them in a state of uncertainty. It was this fear of the unknown that led Naruto to make an unthinkable decision—reviving Kaguya herself. The Sage had always insisted that Kaguya had not been inherently evil, that her descent into madness was born of fear and isolation. Naruto, ever the gambler for peace, chose to restore her sanity, believing her knowledge and power could become an asset in the fight to come.

Reviving Kaguya was no simple feat, but the gamble paid off. Once her fractured mind was restored, Kaguya revealed truths even more dire than what they had imagined. The Otsutsuki clan's motives extended beyond conquest—they sought to harvest and destroy entire worlds. Their power was unimaginable, their reach infinite. Time was running out.

While Naruto rallied to prepare the world against the external threat, internal struggles remained. Peace, as he had learned, was not a state but a constant effort. Human nature, flawed and selfish, resisted perfection. Evil did not vanish when Naruto ascended to leadership; it simply burrowed deeper into the shadows. The world, while unified, remained fractured by fear—fear of him. Naruto was the strongest being on the planet, his power unmatched, and that terrified people. They trusted him, but they also feared the possibility that one day he might impose his will by force.

Naruto understood that trust could not be built on words alone. To allay the fears of the nations, he took a controversial step: he married into each of the major lands, creating a web of alliances that ensured every nation's voice would be heard. It was a pragmatic choice born of necessity, yet Naruto, true to his nature, treated his new wives not as tools but as partners. Over time, love grew between them, and the once-diminished Uzumaki Clan became a sprawling family of fourteen.

Though these marriages secured political stability, they brought new challenges. As much as Naruto could face gods and monsters without fear, the trials of being a family man were another matter entirely. Balancing the demands of leadership, the looming Otsutsuki threat, and the complexities of his large family tested even his seemingly boundless resolve.

Despite it all, Naruto remained steadfast. He believed in the path he had chosen, even when it was fraught with hardship. For every challenge, he found strength in his allies, his family, and the unwavering belief that humanity was worth fighting for. As the Otsutsuki threat loomed closer and humanity's darker tendencies simmered beneath the surface, Naruto pressed forward with a simple hope—that when it was all over, he would not only survive but also find happiness and peace in the world he had dedicated his life to protecting.

Thirteen years had passed since Naruto Uzumaki ascended as the Emperor of Mankind, uniting the world under his leadership. Now 32 years old, he had matured into a commanding and dignified figure whose presence alone inspired awe and respect. Standing at 190 cm, his physique was a testament to his disciplined life, his muscular frame etched with intricate seals designed to protect him from harmful effects and enhance his already immense power.

His long blonde hair flowed as it always had, and he carried himself with a regal air. Dressed in black pants and a crisp white shirt, Naruto's attire, adorned with golden earrings, a powerful ring, and a majestic crown, spoke of both elegance and authority. These artifacts were more than decorative—they were powerful creations imbued with protections and enhancements, befitting the ruler of a united world.

Naruto's imperial palace was a marvel of beauty and power, nestled on the rebuilt Uzu, now a thriving hub of culture and governance. It stood as a symbol of unity, a beacon for the new era. Inside his office, bathed in warm light, Naruto was seated, his gaze distant, his mind heavy with thought.

"Husband, what are you thinking about?"

The melodic voice brought Naruto back to the present. He opened his eyes to see Kaguya, his ancestor-turned-wife, standing gracefully before him. Though once revered as the Rabbit Goddess, Kaguya now revealed a softer side of herself, one filled with vulnerability. Despite her immense power, she relied on Naruto for emotional and spiritual support, her fear of loneliness and her struggle with her past never far from her mind.

Naruto reached out, taking her hand in his. It was a simple gesture, yet it spoke volumes about the bond they shared. Though she was immortal, Naruto had achieved the same state through groundbreaking experiments. By incorporating Kaguya's blood and many other clans DNA, he had transformed his body into that of an Otsutsuki. The changes in his physique included horns, though he kept them hidden to avoid alarming others or causing unintentional damage. His transformation had made his body a living powerhouse, permanently in Six Paths Sage Mode and drawing nature energy from the universe itself.

"Nothing," Naruto replied, stretching his arms. "I was just taking a short nap."

Kaguya smiled knowingly as she floated closer, her mastery of space allowing her to bypass doors with ease. She stood behind him, wrapping her arms around his back. Her embrace was warm and grounding, a reminder of her care and understanding.

"Are you sure the mighty Uzumaki Naruto was taken down by desk work? Or is it something else, something closer to your heart?" Kaguya's tone was sweet but teasing, her words cutting through his guarded facade.

Naruto sighed, leaning back in his chair as he felt the weight of her question. It wasn't the monumental responsibilities of overseeing the world's technological, medical, and educational advancements that troubled him. He had an extensive network of officials to manage the minutiae, though he still reviewed every significant decision to ensure integrity at all levels. His Otsutsuki-enhanced physiology allowed him to forgo food and rest, sustaining him through the boundless energy of the universe. No, Kaguya was right—his burden wasn't his work but his family.

"You already know," Naruto admitted with a chuckle, pressing a hand to his face. "It's Boruto and Benimaru. I don't know how to help Boruto overcome his struggles, and Benimaru needs another lesson—preferably one that involves a good spanking. Why are those two so mischievous? Why can't they be more like the girls?"

Kaguya chuckled softly, brushing a strand of his hair away from his face. "I am aware, but you know you can only do your best, like always."

She turned him around to face her, placing a gentle kiss on his hand. Her presence calmed him, as it always did, even in the midst of chaos. Naruto smiled faintly, his mind briefly drifting from his responsibilities as he cherished this moment with her.

Parenthood, as Naruto had learned, was an entirely different battle. Despite his unparalleled strength and intellect, his children constantly challenged him in ways no enemy ever had. Boruto's inner turmoil, Benimaru's rebellious nature, and even Asura's antics often left Naruto exasperated. Yet, for all their difficulties, his children were his greatest treasures.

In this quiet moment, Naruto allowed himself a brief respite, leaning on Kaguya's support before returning to the duties that awaited him. For all the challenges he faced—both as a ruler and as a father—he would carry on. After all, it was his unwavering belief in the future, in his family, and in humanity that made him who he was: the Emperor of Mankind.
