Konoha
The m sunlight streamed through the windows of the Hokage office, illuminating stacks of paperwork piled high on the desk. Hiruzen Sarutobi, the Third Hokage, leaned ba his chair, a cloud of smoke rising zily from his pipe. His gaze drifted toward the Hokage's mo, etched into the mountain outside. Though he held the title of the most powerful and respected figure in the vilge, his face betrayed only sadness and weariness.
Konoha had endured unspeakable losses. The Third Great Ninja War had straiheir forces too much, f them to fight on every front against every ninja vilge out there, and after the war ended and the vilge was enjoying a time of peace. Barely a year ter, the ails rampaged through the vilge, leaviru and grief in its wake.
Minato Namikaze, the Fourth Hokage, had sacrificed his life to seal the beast and save the vilge, but the cost of that heroic act was staggering—the life of the Kage and the Jinchuriki of the vilge almost crippling the vilge's strength.
Ninjas, civilians, and their families—all suffered during both of these events. The orphanages, once able to house a manageable number of children, were now bursting at the seams. New facilities had to be hastily established, yet even those were struggling to keep up. The increase in the number of orphans was really heart-wreng.
Hiruzen sighed deeply, his pipe resting momentarily on the desk. With a heavy heart, he turned his attention back to the endless paperwork, his day beginning as it always did.

In one of the overfilled orphanages, a young boy stirred in a dimly lit room. Bandages ed around his head, evidence of a ret injury. His small frame rested on a thin mattress, and a faint medial st lingered in the air. As the boy's eyelids fluttered open, a sharp, searing pain shot through his skull.
"Argh, what is this headache?" he muttered under his breath, his voice weak.
The pain was unlike anything he'd felt before. It wasn't just pain—it felt as though his very mind was being reshaped, and not just mind but even something deep ioo was going through the same procedure. He groaned and raised a trembling hand to his forehead, freezing mid-motion when his eyes caught sight of his own fingers.
They were small. Too small.
Panic surged through him. His wide eyes sed his surroundings, taking in the unfamiliar room. 'This isn't the hospital I was admitted in,' he thought. 'Where am I? What... what happeo me?'
F himself to sit up, he caught a glimpse of his legs beh the bhey were shorter, his body smaller than he remembered. His heart pounded as a terrifying thought crept into his mind. 'Did I... go ba time? No, I don't want to suffer through all that once again,' he nearly cried.
Before he could process further, the door creaked open. A middle-aged man with graying hair entered, his ed gaze fixed on the boy. "Kaida, are you awake?" he asked gently, pulling a chair close to the bed.
The boy frowned, fusion written all over his face. "Who are you?" he asked, his voice cautious. "And why are you calling me Kaida?"
The man's expression darkened. "It seems the injury affected your memory," he said, worry evident in his tone. "You don't remember anything, do you?"
Kaida shook his head, the movement causing another spike of pain. He clutched his temple, the headache he had been experieng till now increasing further, as fragmented memories began flooding in—memories that weren't his own. A young boy's ughter, a pair of warm smiles, and then... darkness. Too much. His body couldn't ha. With a sharp gasp, he colpsed bato the bed, unscious.

When he woke, it was to the soft hum of voices outside his room produced by the fan rotating above him. The headache had dulled to an ache, but his thoughts were clearer. He y still, pretending to be asleep, as he pieced together the fragments in his mind. Memories—new, fn memories—whiehow felt personal like he himself had lived that life as well. But they weren't his. They beloo the boy this body once beloo.
Kaida Senju.
A sharp intake of breath escaped him. 'Senju? No way...' The realization hit like a lightning bolt. The he faces, the events, surroundings—everything poio one undeniable fact. 'I transmigrated. And into the Naruto world, of all pces.'
His disbelief gave way to panic. 'How? Why? I don't even remember dying. Isn't that supposed to be a prerequisite? And why this world? A pce filled with ninjas capable of ending lives with a flick of their fingers?'
Taking deep breaths, he forced himself to calm down. The memories tio surface, him glimpses of Kaida Senju's life. His parents, Asami Senju and Aiko Uchiha, were among the many who died during the ails attack. Orpha just five years old, Kaida had been brought to this orphanage, narrowly esg recruitment by Root.
'Lucky me,' he thought bitterly. 'At least Danzo didn't get his hands oherwise I would have lived this life as a puppet of a deranged person till who knows how long.'
But the more he delved into these memories, the more he realized how dire his situation was. 'This isn't a game. This is real. If I don't take this seriously, I'll be dead before I even hit puberty.' The news of the death of a neighbor who had just bee genin a on a mission only to e back blown up because some bandits attacked the caravan they were proteg resent in the memories of the boy. Even though that little boy didn't uand much of it, now they pyed an important role.
A strange warmth stirred within him, interrupting his grim thoughts. It was subtle at first, like a gentle current, but it grew stronger, flowing through his body in a rhythmic pulse. He closed his eyes, fog on the sensation.
'Is this... chakra?' The realizatiht a faint smile to his lips. 'So, this body's chakra work is active. That's something, at least.'
But he forcefully turned his thoughts into practical ones. 'All right, let's assess. If I'm five years old now, that puts me four years ahead of Naruto's geion. The Uchiha massacre will happen in about seven years, the in Exams in twelve, and the Freat Ninja War in sixteen. No, that is the amount of time I have fetting at least strong enough to handle myself in this dangerous world.'
The gravity of his situatioled over him. 'If I'm going to survive, I o get stronger. Fast.'
Steeling himself, Kaida opened his eyes and sat up. It was time to embrace his new identity, his new life. "Kaida Senju, huh?" he muttered. The name felt fn on his tongue, but it was his now. 'Let's see what this world has in store for me.'
