The five years between Karan's first day on the Academy floor and his last did not compress the way memory liked to compress things, all highlight reel and no boredom. He lived every single one of them in order, the ordinary way, and if there was one thing Karan came to be quietly proud of by the end of it, it was that he'd never once tried to cheat his way past that plain, unglamorous truth.
He got better because he drilled the same stance four hundred times until his legs stopped arguing with him about it. He learned the clone technique on the ninth attempt, not the first, and only after Kaoru — who'd managed it on his sixth, and apologized for it so sincerely that Karan had laughed until his sides hurt — walked him through exactly where his hand seals were going soft. He grew two inches, then three, then stalled out miserably for almost a year while half his classmates shot up around him, and complained about it to his father with the wounded dignity of a boy who had apparently expected reincarnation to come with a height guarantee.
Minato, meanwhile, grew from a toddler who tripped over his own feet chasing fireflies into an eight-year-old who could not, by his teachers' increasingly bemused reports, be caught in a game of tag by anyone in his year group, clan kids included. He started at the Academy himself the year Karan turned twelve, trailing after his older brother's old classroom door on his first morning with a mixture of terror and undisguised excitement that made something in Karan's chest ache in the specific, helpless way only a little brother had ever managed to produce.
"You'll be fine," Karan told him, crouching down to fix Minato's collar, which had somehow gone crooked in the four minutes since Emiko had straightened it. "Better than fine. Probably better than me."
"That's not hard," Minato said, with the perfect, guileless cruelty of a little brother who has learned exactly which buttons exist and is delighted to have found them, and then bolted through the Academy doors before Karan could retaliate, laughing the whole way.
There he is, Karan thought, watching him go. There's the boy this whole world is going to end up needing. He let himself feel it for exactly as long as it took to blink hard once, the way he'd learned to do with the parts of this life that threatened to overwhelm him, and then he went to find his own classroom, because graduation exams did not care how proud a person's chest currently felt.
The graduation exam itself was, in the end, almost anticlimactic — which Karan decided afterward was probably the point. Five years of drilling did not resolve themselves in some dramatic final trial. They resolved in a plain, sparse examination room, a chunin proctor with a checklist, and a clone technique that Karan performed clean and steady on the first try, years of practice compressed into three unremarkable seconds that nobody watching would ever think to call heroic.
"Pass," the proctor said, already reaching for the next name on the list, and slid a forehead protector across the table like it was a completed form rather than the single object Karan had been quietly orienting his entire second life around since he was two years old.
He held it for a long moment before he put it on. Metal, cool under his fingers, the leaf symbol stamped into it with the same unglamorous, functional precision as everything else this village made. Not a legend's headband. Not the artifact of some prophesied hero. Just the ordinary, correct next step for an ordinary, correctly-prepared genin — which was, Karan reflected, tying the cloth behind his head, exactly what he had spent five careful years making sure he actually was.
Kaoru passed the same afternoon, two rows down, and found Karan afterward in the milling crowd outside with his own headband already tied, sharingan still unawakened, shoulders — Karan noted, with a private, considerable satisfaction — no longer locked in that permanent clan-crest brace they'd started in five years ago.
"We made it," Kaoru said, sounding faintly disbelieving of the fact even as he said it.
"Told you it wasn't hard," Karan said, and got shoved for it, and counted that, too, among the ordinary, correctly-earned things this life had actually given him.
Team assignments came three days later, and Karan found himself placed under a jonin sensei he'd never crossed paths with before — a lean, quiet woman named Fumiko, dark hair cropped short and practical, a reputation among the other genin's parents for being thorough rather than flashy, which suited Karan considerably better than flashy would have. His teammates were a pair of Academy classmates he knew only in passing: a serious, methodical boy named Tarou with an Aburame-adjacent bloodline Karan couldn't immediately place, and a sharp-tongued girl named Sae whose taijutsu had been, by Karan's careful five-year accounting, the best in their entire year group, clan children included.
None of them were characters Karan recognized from the story he remembered. He noticed that, cataloged it the way he'd learned to catalog everything, and felt something unexpectedly loosen in his chest at the realization. Not everyone in this world owed him narrative significance. Some of it — maybe most of it, if he let himself actually think about it — was just going to be his own life, built one ordinary team meeting at a time, with people history had simply never bothered to write down.
Good, he thought, settling onto the bench beside two strangers who were about to stop being strangers. That's exactly how it should be.
He didn't go looking for the Chamber's door that first night. He'd promised himself, five years ago on a rain-grey afternoon, that he wouldn't rush this part, and he intended to keep that promise even now, with the headband still stiff and new against his forehead and the temptation sitting right there behind his ribs like it had been waiting patiently the entire time.
He waited until his first D-rank mission was behind him — an unglamorous, faintly ridiculous afternoon spent chasing a landowner's escaped cat through three separate gardens with Tarou and Sae, Fumiko-sensei watching from a rooftop with the amused, long-suffering patience of a woman who had clearly done this exact mission more times than she cared to count — and only that evening, alone in his room, did he finally close his eyes and reach for the door the way he'd been reaching for it, uselessly, since he was two years old.
It opened differently this time.
There was no polite, locked message waiting for him. Instead, the white space behind his eyes unfolded — actually unfolded, edges pulling back like a held breath finally releasing — into something with dimension and weight and the particular waiting stillness of a room built specifically for him.
[HYPERBOLIC CHAMBER — RANK VERIFIED: GENIN] [TIME DILATION RATIO ACTIVE: 10 DAYS INSIDE : 1 DAY OUTSIDE] [MAXIMUM SINGLE-ENTRY DURATION: APPROX. 6–7 INSIDE-DAYS]Welcome, User. The door is open.
Karan stood very still in his own bedroom for a long moment, heart going a little too fast for a boy who was, technically, doing nothing more strenuous than sitting cross-legged on his own bed.
Five years. Five years of drilling stances and failing clone jutsu and growing three miserable inches at a time, precisely because he'd refused to let this exact moment arrive a single day before he was ready for it. And now here it was — a door that would let him trade a single outside afternoon for the better part of a week's uninterrupted training, over and over, for as many years as he had left before the war and the mask and the fox came due.
Okay, he thought, and this time the thought didn't feel like a coal held stubbornly alight against the dark. It felt like the beginning of something he'd finally, actually earned the right to start.
Let's go to work.
He stepped through.

Coming in Chapter 6 — Six Days in a Blink
Karan's first real stretch inside the Chamber — and the first honest look at what six subjective days of solitary training actually costs a twelve-year-old boy, long before he's anywhere near strong enough for it to show.
