The first thing Karan understood, before he understood his own name, was that dying hurts less than being born.
There had been a highway, headlights that didn't slow down in time, and then nothing — a long, grey, dreamless nothing that he later suspected had been kinder to him than it had any right to be. And then there was this: too-bright light through eyelids that wouldn't obey him, air that scraped going into lungs that had apparently never been used before, and a pair of hands the size of his entire body holding him like he was something precious and breakable at the same time.
He tried to scream in protest and discovered that was, apparently, exactly what he was supposed to do.
"There he is," said a voice above him, rough with exhaustion and thick with something that took Karan several long, disoriented seconds to place as love. "There's my boy. Emiko, look — he's got your nose."
A second voice laughed, worn thin and watery with hours of labor but warm all the way through it. "And your terrible hair, from the looks of it."
Namikaze.
The word arrived a moment later, tucked into something a nurse said near the doorway — congratulations, Namikaze-san— and it landed in whatever passed for Karan's mind like a stone dropped into still water, ripples going out and out and refusing to stop.
He knew that name. Not from these two people holding him, whoever they turned out to be — he knew it the way you know the title of a legend before you've met a single person in it. There was only one Namikaze history would ever bother writing books about, and that boy hadn't even been conceived yet.
He turned his unfocused newborn eyes toward his father's voice anyway, some new-old part of him needing to check, and found spiky blond hair, kind, tired eyes, and a bone structure that Karan had absolutely, uncannily, impossibly seen before — not on this man exactly, but staring back at him, years and a full lifetime from now, older, sharper, framed by a hat and coat that didn't exist yet either.
Oh, he thought, with the particular clarity of a man watching a truck he can no longer avoid. Oh, no. I'm not just in Naruto. I'm in the Namikaze house, before there's even a Minato to have one.
He grew, as babies do, entirely without his own permission.
The world in those first months was soft-focus and enormous: the wood grain of the ceiling above his crib, the sound of his mother's laughter through paper-thin walls, his father's chakra signature moving through the house like a familiar warmth that Karan's newborn senses could somehow feel before he had words to describe feeling it.
His mother's name was Emiko — no clan name attached to it that Karan could place, which meant either she came from civilian stock or from a family too minor for the story he remembered to ever mention. His father's name was Namikaze Hiroshi. Not a clan head, not a famous name in any Databook Karan could recall — which told him precisely nothing, since half the shinobi who mattered in the war years to come weren't famous yet. Jonin-sensei, if Karan's read on the deference other shinobi showed him at the door was accurate. Steady hands. A habit of humming off-key when he thought no one was listening.
And upstairs, in a room Karan wasn't yet mobile enough to reach, there was a nursery being prepared for a brother who did not exist yet — because if the timeline in Karan's memory held even loosely, Minato Namikaze wasn't due to be born for another three years.
Three years, Karan thought, lying in his crib one night, tracking a moth's shadow across the ceiling with newly-focusing eyes. Three years before the Yellow Flash of Konoha is even a concept, let alone a legend. Nine, maybe ten, before the Third War starts eating genin alive. Twenty-something before a man in an orange spiral mask puts a nine-tailed fox through this village like a wrecking ball through wet paper.
He didn't know the exact year. He didn't know how much slack he had. He knew only that the slack existed, that it was finite, and that every single day of his old life he'd spent reading about these people dying had just become a countdown clock with his new family's names on it.
Minato survives childhood, he reminded himself, fighting down a rising, formless panic that had no business existing in a body this small. He grows up, becomes Hokage, marries a girl who isn't even born yet, and dies protecting his own newborn son the night the Kyuubi is set loose. Unless I change that. And I am going to change that.
Unless something changed.
Unless he changed something.
The thought sat in his infant chest like a coal, small and stubborn and refusing to go out.
He was two years and four months old — old enough to toddle, not yet old enough to be trusted not to eat dirt, by his mother's occasionally exasperated accounting — when the System first spoke to him.
It happened on an afternoon that started unremarkably. His father had taken him out to the yard, ostensibly to "get some air," which Karan had come to understand was Namikaze-household code for Dad wants to practice something and doesn't want to explain it to Mom yet. Hiroshi knelt in the grass, held out one broad palm, and let a thin, visible thread of blue-white energy coil across his skin like a living thing.
"Chakra," his father said, in the deliberately slow, deliberately clear voice adults use on children they suspect understand more than they let on. "Can you feel it, Karan? Reach out. Not with your hand. With—" he tapped his own chest, then his stomach, "—here."
Karan, who had spent two years carefully not showing off any suspicious depth of comprehension, reached out anyway. Partly because he was, on some fundamental level, still a child, hungry and curious in a way that outran caution. Partly because some quiet, patient part of him had been waiting for exactly this moment since the day he woke up screaming in this world, sensing that this — chakra, the door into everything this world's power was built from — would be the key that turned the lock on whatever had followed him across the boundary of death.
He felt something turn over inside him like a held breath finally released.
And then the world went very quiet, and very white, and a single line of text unspooled across his vision the way subtitles might, except there was no screen, and no one else in the yard so much as blinked.

Karan, two years and four months old, sitting in the grass in front of a father who had no idea his son's inner world had just been rearranged from the studs out, thought a single word with all the force his small mind could gather.
Yes.
[Acknowledged. Welcome, User. Your journey begins.]
His father, misreading the sudden, fierce concentration on his son's face as simple effort, laughed warmly and ruffled his hair. "There you go! Good — that's the feeling. You're a natural, little man."
You have no idea, Karan thought, and for the first time since he'd opened his eyes in this world, he found himself grinning.
Somewhere behind his ribs, a door he couldn't see had just been built. He didn't know yet what it would look like inside, or what it would cost him to walk through it again and again for years on end while everyone he loved kept aging at the ordinary, merciless, one-day-per-day rate the rest of the world was stuck at.
He only knew that for the first time since the headlights, he had something the story itself hadn't given him.
He had time. Not much of it, from the outside.
But from the inside — if the System was telling the truth — he was about to have more of it than anyone alive.
