The Land of Iron stood as a neutral nation strategically positioned between the territories of the five great ninja kingdoms, its snow-covered mountains and ancient traditions serving as a buffer zone between the major powers.
Several decades earlier, the Five Kage had convened the historic Five Kage Summit in this very location, an event that had marked the beginning of the Third Ninja World War and set in motion conflicts that would shape the ninja world for years to come.
Now, the Fourth Ninja World War was about to commence from this same neutral ground, but the circumstances could not have been more different.
The five ninja nations that had been bitter enemies during that previous conflict had now united to form an unprecedented alliance—the largest military cooperation in recorded ninja history.
In the main command center of the Allied Ninja Forces, Minato stood holding a specially crafted forehead protector that bore the kanji character "忍" (ninja) etched prominently across its metal surface.
This symbol had been prepared overnight by representatives from each village after the Five Kage had made their historic decision to form the Allied Ninja Army. The headband represented not loyalty to any single village, but dedication to the protection of the entire ninja world.
With deliberate ceremony, Minato removed the Konoha forehead protector that he had worn with pride for so many years and replaced it with this new symbol of unity. The gesture carried profound symbolic weight—even the Hokage was setting aside village loyalty in favor of a greater cause.
Outside the headquarters building, an enormous gathering of ninja had assembled from every corner of the known world. The sheer number of warriors was staggering, representing the largest military force ever assembled in ninja history.
These thousands of fighters had been organized into several distinct operational units, each one composed of multiple thousands of personnel and designed to fulfill specific tactical roles in the approaching conflict.
The Allied Ninja Forces had been structured into five main combat divisions and four specialized support departments, each organized according to their unique capabilities and strategic functions.
The First Division consisted primarily of ninja equipped with various weapons and specialized in mid-range combat techniques. Many of these warriors looked with curiosity at the two distinctive figures who stood at the front of their formation.
"I honestly never imagined that there would come a day when the five major ninja nations would unite in common purpose," Sakumo Hatake said with a gentle smile, his voice carrying the wisdom of someone who had witnessed decades of conflict and cooperation.
"Is that so?" replied the young man standing beside him.
The speaker was a dark-skinned ninja with distinctive white hair who carried a broad sword across his back. A black lightning bolt tattoo marked his left arm, identifying him as a warrior from the Hidden Cloud Village.
Despite his naturally relaxed demeanor, Darui found himself setting aside his usual casual attitude in the presence of the legendary figure beside him.
After all, Konoha's White Fang had achieved fame throughout the ninja world many years earlier, and his appointment as captain of the First Division had been met with universal acceptance. His reputation commanded respect from ninja of every village.
"Kurotsuchi, the war is about to begin, so please try not to look so listless all the time," Kitsuchi said with a helpless expression as he glanced at his daughter, who stood beside him in the formation.
As captain of the close-combat Second Division, he understood better than most that his forces would be responsible for the front lines of battle, making them among the most endangered units in the entire alliance.
"I understand perfectly, Dad. You're really being annoying about this," Kurotsuchi replied with an impatient pout, stretching her arms as if the very discussion was tiresome.
Kitsuchi shook his head with fond exasperation, his gaze shifting toward the front of the Third Division with an expression that carried complex emotions.
At the same time, Jiraiya noticed Kitsuchi's attention and offered him a warm smile of acknowledgment.
The two veteran ninja had fought against each other numerous times during the brutal conflicts of the Third Ninja World War, exchanging attacks and strategies as representatives of opposing nations. Now they found themselves fighting side by side as unit leaders of the Allied Ninja Forces.
"Is that really one of the legendary Sannin? The current supreme commander of the allied forces and mentor to the Fourth Hokage himself, Master Jiraiya?" some of the assembled ninja whispered among themselves with obvious curiosity.
As Minato's status in the ninja world had continued to rise over the years, Jiraiya had naturally received increased attention and recognition as the teacher who had shaped such an extraordinary leader.
The Third Division had been designated as the force responsible for sustained combat operations, designed to maintain pressure on enemy forces during extended engagements.
"My name is Nawaki, and from this moment forward, we must fight side by side to protect this world and everyone we care about!" Nawaki announced with obvious excitement to the members of his division.
However, when he finished his enthusiastic introduction, the assembled ninja fell into an uncomfortable silence.
As a professional warrior, there were indeed very few individuals who possessed Nawaki's naturally optimistic and energetic personality. His genuine enthusiasm seemed almost out of place in the grim atmosphere of pre-war preparation.
"Hehe," Nawaki said with a slightly nervous laugh, realizing that his attempt at motivation had not been particularly well-received. "It seems that I'm not going to be a very popular captain from the very beginning."
The Fifth Division represented a unique combination of samurai and ninja who specialized in unconventional fighting techniques and rare abilities.
The captain of this diverse force was Mifune, the distinguished leader of the Iron Country's warrior class and one of the most respected figures in the neutral nation.
As a powerful individual from the same generation as the Third Hokage and the legendary Hanzo of the Salamander, Mifune's combat abilities and tactical expertise were widely acknowledged throughout the ninja world.
In addition to the five main combat divisions, the Allied Ninja Forces included four crucial specialized departments: the Surprise Attack Division, the Medical Support Division, the Intelligence Division, and the Sensory Division.
Compared to the massive numbers in the main combat forces, the personnel count in these specialized units was significantly smaller. However, there was no doubt that they represented absolutely indispensable components of the war effort.
"There are so many people here," Chiharu observed as she surveyed the enormous crowd of allied forces spread across the landscape.
Although she was quite young, she had already completed numerous missions as a Chunin of Konoha and had demonstrated exceptional skill in medical ninjutsu. Just before the war began, she had been promoted to the rank of Special Jonin in recognition of her abilities.
"As medical ninja, we must dedicate ourselves to protecting the lives of all coalition members," said the white-haired young man standing beside her. "This is our most sacred responsibility."
He pushed his glasses up his nose as he spoke, his gentle expression reflecting the compassionate nature that made him well-suited for medical work.
"Senior Kabuto, you truly are such a kind person," Chiharu replied with a warm smile.
"War brings nothing but suffering and sorrow to the world, yet we have no choice but to fight this particular conflict," Kabuto Yakushi continued thoughtfully.
"Therefore, what we can do is help everyone bring it to an end as quickly as possible, minimizing the casualties and pain along the way."
Although Kabuto was relatively young, he had been recommended by Tsunade herself to serve as captain of the Medical Support Division. His exceptional skills and compassionate nature had made him an obvious choice for the position.
He had grown up in an orphanage in Konoha, where Nono Yakushi, the director, had treated him with extraordinary kindness despite his status as an orphan from a foreign land. That early experience of compassion had shaped his dedication to healing and protecting others.
"Senior Shin, it's wonderful that we're fighting side by side once again," Sai said with one of his characteristic smiles as he looked at his fellow warriors in the Surprise Attack Division.
Shin offered Sai a gentle smile in return and nodded with quiet acknowledgment of their shared history.
Both young men then turned their attention to the figure who stood at the head of their formation.
"Itachi, please provide us with your guidance during the battles ahead," Sai said respectfully.
"Of course," Uchiha Itachi replied, his gentle smile carrying both warmth and the quiet authority that made him such an effective leader.
As captain of the Surprise Attack Division, Itachi commanded the respect and loyalty of some of the most skilled covert operatives in the allied forces.
Inside the headquarters building, a massive spherical construction filled with water dominated the central command area. At this moment, dense points of light flickered continuously within the center of the water sphere.
Each point of light represented the chakra signature of a ninja from the coalition forces assembled outside. As captain of the Intelligence Division, Yamanaka Inoichi sat positioned in front of the sphere, surrounded by other members of his specialized unit.
The Intelligence Division bore responsibility for coordinating all combat operations and transmitting real-time updates about the status of various units throughout the battlefield.
Seated nearby was Suzuka Hatake, who served as captain of the Sensory Division and whose abilities would be crucial for detecting enemy movements and preventing surprise attacks.
"Is this truly the extent of Konoha's current strength?" the Tsuchikage Onoki and the Raikage murmured to each other, their voices carrying complex emotions as they observed a particular group gathered in one corner of the headquarters.
In addition to the Konoha warriors who had already been assigned as captains of various divisions, the most elite fighters from the village had assembled together in the command center.
The gathering included Uchiha Yoruki, Uchiha Shisui, Tsunade, Kushina, Kakashi, and two notably young figures who seemed to command unusual attention.
Naruto and Sasuke stood facing each other, both experiencing strange sensations in their bodies and minds when they made eye contact. There was something indefinable connecting them, a resonance that neither fully understood but both could feel.
The reason these individuals had not been distributed among the various combat divisions was to maintain tactical flexibility and ensure that their exceptional abilities could be deployed wherever they would be most effective.
The combat strength represented by each of these individuals was equivalent to what entire divisions from other countries could field. It was no exaggeration to state that, excluding the numerical advantage in basic ninja personnel, Konoha's elite strength equaled or even exceeded the combined power of the other four ninja nations.
Furthermore, the Fourth Hokage himself was a warrior whose abilities transcended what any of the current Four Kage could hope to match. His presence alone fundamentally altered the strategic balance of the conflict.
The current incarnation of Konohagakure represented undoubtedly the most powerful moment in the village's entire history since its establishment by the First Hokage.
This strength had not come through conquest or oppression, but through the development of exceptional individuals who embodied the Will of Fire and the village's commitment to protecting not just their own people, but the entire ninja world.
As the assembled forces prepared for the greatest conflict in ninja history, there was a palpable sense that they stood at a crossroads that would determine the fate of every living being in their world.
The Fourth Ninja World War was about to begin, and the unified strength of the ninja nations would finally be tested against the apocalyptic ambitions of those who sought to remake reality itself.
