Flashback
The last thing Ezio Auditore remembered was the warmth of the sun on his face. His body, old and worn from the years of fighting, was resting peacefully on a bench in the countryside of Florence. His hands, once deadly with a hidden blade, now trembled with age. He had lived a life full of victories, losses, and hard-learned wisdom, carrying on the legacy of the Assassins for decades. In his final moments, he had accepted the peace that death would bring—a well-deserved rest after everything he had endured.
But rest never came.
Instead, Ezio awoke in the body of a young child. At first, he thought it was a dream—one of those vivid dreams where the air feels too real, where his senses are too sharp to be imagined. But as days passed, the dream refused to end. The smell of the earth, the rustle of leaves, the foreign words spoken by the people around him—it was all real. He wasn't in Florence. He wasn't in Italy. He wasn't even in his own world anymore.
He was reborn, inexplicably, in the body of a boy no older than four. His name? Ezio Uchiha.
Ezio didn't know how it had happened. Was it divine intervention? Isu ? The work of the Pieces of Eden? Or perhaps something else entirely? The Assassin Brotherhood had always spoken of mysteries beyond human understanding, but this? This was something far beyond what even the greatest minds of his time could comprehend. He was young again, agile, and full of energy. What troubled him most was not just the physical change.
This new life was a world of shadows, one dominated by warriors who called themselves Shinobi—ninjas who wielded abilities that defied the laws of nature. Powers that could mold the elements, reshape landscapes, and even bend time and space. It was a far cry from the hidden blades and parkour of his old world. Here, strength came not only from training but from bloodlines and talent. The Uchiha name carried weight, but it also carried darkness. He is basically in a clan that possesses special ocular abilities, it appears when you lose someone important to you. Theses eyes are called Sharingan.
He sat on the doorstep of his home, eyes scanning the bustling village of Konoha. People passed by with hurried steps, some wearing uniforms adorned with a strange symbol—a leaf, they called it. Others, older and sterner, bore the forehead protectors of shinobi. Behind him, the walls of the Uchiha compound felt like a cage. It was different from Florence's grand estates or the freedom he once knew atop the rooftops. This world had its own rules, its own kind of tyranny.
Ezio had learned that quickly. This was not a peaceful world, nor was it a just one. War was everywhere, even if the village itself seemed calm on the surface. The First Shinobi World War had been raging for some time now, and whispers of an upcoming peace treaty between Konoha and Kumogakure villages were all anyone talked about. Ezio could feel the tension in the air, thats a common feeling for him.
"Ezio Uchiha... I can't get used to this crap, I'm too old for this." In truth, he constantly worried about his family but he had to force himself to accept his reality.
Today, however, was a different kind of battle for him. Today was the first day of the shinobi academy.
As much as Ezio wanted to reject this new reality, to retreat into his memories of the past, he knew that there was no going back. He had to adapt. He had to learn the ways of this world if he ever hoped to find out why he was here, and more importantly, what he was meant to do.

Ezio arrived at the academy gates with a small group of children, most of them around his age. They were excited, bubbling with energy, already chatting about what techniques they would learn. But Ezio, accustomed to solitude, stayed silent, observing them from the fringes. There were faces he would come to know well, though he didn't know it yet. One boy, with white hair and a mischievous grin, was jumping around, boasting to anyone who would listen. Jiraiya, someone called him.
A blonde girl, with a confident air, stood nearby, watching the other children with sharp eyes. She seemed less childish than her peers.
There was also this child with reptilian eyes who displayed behavior that was far too mature for a child.
"Hell, even children in my world aren't this aware at this age." he muttered unconsciously under his nonexistent beard.
As the teachers called them into the academy, Ezio took a deep breath. His sharp instincts from his days as an Assassin kicked in, assessing the area, noting every possible exit, and eyeing the adults with the authority of a seasoned warrior. But he was in a child's body, and that made everything feel both strange and overwhelming.
Ezio sat quietly at the back of the class, his sharp eyes taking in every detail of his surroundings. He was used to blending into the background, observing, analyzing. The academy classroom was filled with the chatter of children, all of them eager to make friends and show off what little they knew of the shinobi arts. To him, it was chaos.
"Alright, everyone quiet down," a teacher called out, stepping to the front of the room. "We'll begin with introductions. Stand up, say your name, and something about yourself."
Ezio leaned back, letting the others go first. He had no desire to draw attention to himself—at least, not yet. He needed to learn the dynamics of this place, figure out who was who. He had always been a quick study in his old life, and it seemed that skill hadn't abandoned him even in this new, strange world.
A boy with messy white hair and a wide grin stood up first. "Jiraiya!" he declared loudly, puffing out his chest. "I'm gonna be the greatest shinobi ever! You'll all see!"
The class erupted into laughter, some of the children cheering, others giggling behind their hands. Jiraiya seemed to love the attention, basking in the spotlight.
Next was a blonde girl with confident posture and sharp eyes. She stood with a grace that reminded Ezio of the nobility back in Florence. "I'm Tsunade," she said coolly. "My grandfather is the First Hokage, Hashirama Senju." There was a collective gasp from the room, and Ezio noticed how everyone's posture changed, as if they were suddenly in the presence of royalty. Tsunade didn't seem to care. "And I'm going to surpass him," she added, her voice full of certainty. Ezio could see that her words weren't just for show. She believed in them.
Naturally, the Uchiha clan was not the only one in this village. The Senju clan had nothing to envy, on the contrary it is the most influential clan in the village currently.
Hashirama Senju, the man hailed as the strongest, considered by many as the God of Shinobis. In this village, every person knows the name of the First Hokage, this girl being his granddaughter, this will certainly attract a lot of attention.
The next boy to stand up had an eerie calm about him. His skin was pale, his eyes narrow and snake-like. "Orochimaru," he said quietly, though his voice carried a strange weight. The class fell silent as he spoke, a subtle shift in the atmosphere that Ezio found intriguing. Orochimaru didn't boast, didn't claim any grand dreams. He simply sat back down, leaving a lingering tension in the air.
Then came another girl. This one had dark hair and the unmistakable emblem of the Uchiha, like Ezio. She stood with quiet dignity, her gaze never wavering as she introduced herself. "Naomi Uchiha," she said, her voice soft but firm. "My father is the leader of the clan." She glanced briefly at Ezio, curiosity in her eyes. Ezio didn't react outwardly, but he filed that information away.
Finally, it was Ezio's turn. He stood slowly, feeling the weight of their gazes on him. His mind flickered briefly to his old life, to the days when he had been a master Assassin, a man whose name commanded respect and fear. Now, he was just a child again.
"Ezio Uchiha," he said simply. He had no grand claims to make, no lofty dreams to share. Instead, he added quietly, "I'll do what I have to."
The room was silent for a moment before the teacher nodded and motioned for him to sit. Ezio felt Tsunade's eyes on him for a few moments longer before she finally looked away, seemingly intrigued by his quiet demeanor. He noticed Jiraiya whispering to a few kids behind him, probably trying to make some joke at his expense, but it didn't matter. Jiraiya was the type who liked to stand out, while Ezio was content to watch and wait.
The day continued with lessons on basic history—mostly things Ezio already knew. The world had its differences, but some things were universal: power, war, and the never-ending struggle for dominance. The First Shinobi World War is about to end, but tensions still ran high, and Ezio could feel the underlying unease among the adults. Peace was fragile here, just as it had been in his old world.
During a break, Ezio found himself outside, sitting beneath a tree, watching as the other children played. Tsunade was surrounded by a small group, all of them trying to impress her. Jiraiya was goofing around, pretending to show off techniques he didn't know yet. Orochimaru was off to the side, reading silently, his expression unreadable.
These are the three names he kept in mind, his instinct told him that they would be people who would have an impact later on.
Tsunade's eyes flicked over to Ezio again. She seemed to be sizing him up, trying to figure him out. He didn't return the look, pretending to be lost in thought. He was used to this kind of attention—it was the same when he was younger in Italy. People were always curious about those who kept their distance.
"Hey," a voice interrupted his thoughts. Ezio looked up to see Jiraiya standing in front of him, his hands on his hips. "Why're you sitting over here all by yourself?"
Ezio raised an eyebrow. "I could ask you the same thing," he said evenly, though he knew Jiraiya wasn't the type to sit alone for long based on his personality.
Jiraiya blinked, then grinned. "Fair enough! But you should come over and join us. No need to be so serious all the time."
Ezio smiled faintly, more out of amusement than anything else. "I'll think about it."
As Jiraiya bounced away, clearly satisfied with himself, Tsunade approached. She stood in front of Ezio, hands on her hips much like Jiraiya had. "You're weird," she said, not bothering with pleasantries.
Ezio looked up at her, curious but unfazed. "Weird ? How?"
"I don't know yet," she replied, narrowing her eyes slightly, "but I'll figure it out."
He gave a small nod. "I'm sure you will, Principessa."
Tsunade's eyes widened slightly at the foreign word, but she didn't question it. Instead, she smirked and walked away, leaving Ezio to his thoughts once more. The academy had only just begun, but Ezio could already sense that his presence here wouldn't go unnoticed for long.
