The wind in the Offen Mountain Range was unforgiving, howling through the jagged peaks like a wounded beast. Snow fell in blinding, horizontal sheets, burying the path beneath a heavy blanket of white.
"We’re going to freeze to death," Stark chattered, his arms wrapped tightly around himself.
"Frieren, please tell me we're almost in a town."
"We're lost, Stark," Frieren said plainly, adjusting her scarf. Her calm demeanor completely betrayed the fact that she had led them in the wrong direction for the last three days on their way to Außerst for the First-Class Mage Exam. “The river that existed here 80 years ago seems to have evaporated, so we took a right turn too late.”
Fern let out a long, heavy sigh. "Mistress Frieren, if we don't find shelter soon, we will really freeze."
"Look over there," Frieren pointed a mittened hand toward a ridge.
Through the dense snowfall, a warm, golden light cut through the gloom. As they trudged closer, the silhouette of a sturdy, surprisingly well-built wooden cabin emerged. What caught Frieren’s eye, however, wasn't the architecture—it was the lights. There were no torches, no lanterns, and no magic circles. Instead, intricate, ink-black symbols were etched into the wood and glass, glowing with a steady, self-sustaining warmth.
"Fascinating," Frieren murmured. "I've never seen magic formulas written like this."
Fern stepped up to the thick wooden door and gave it a firm knock. For a moment, there was only the sound of the blizzard. Then, the sound of heavy footsteps approached, and the door swung inward, releasing a wave of incredible, comforting heat.
Standing in the doorway was a young man. He looked to be about twenty-four, with messy, sun-kissed blonde hair, striking blue eyes, and three distinct whisker-like marks on each of his cheeks. He was wearing an oversized, cozy knitted sweater and dark sweatpants, holding a wooden stirring spoon in one hand.
"Oh, hey," the man said, blinking in surprise. "You guys look like you're about to turn into ice sculptures. Come on in."
“Thank you, man, you’re the best,” Stark said, nearly collapsing in relief, rushing past him toward the warmth. Frieren followed, already studying the glowing runes on the doorframe.
But Fern stopped dead in her tracks.
It was a habit for her to subtly read the mana of anyone she met. She let her awareness drift toward the blonde stranger, expecting the shallow, flickering pool of a normal civilian or a low-level hermit.
Instead, her breath completely caught in her throat. Her eyes widened, her pupils shrinking to pinpricks.
It wasn't a pool. It wasn't a lake. It was an ocean with no bottom. The energy rolling off this man felt infinite—a blindingly bright sun contained within a human vessel. But that wasn't even the most terrifying part. Swirling deep within that endless void were nine distinct, ancient, chaotic signatures of power, each one massive enough to level a continent.
Her hands began to tremble. She gripped her staff so tightly her knuckles turned white.
Every instinct she possessed screamed at her to run.
Yet the man standing before them only smiled awkwardly and stepped aside to let snow melt harmlessly off their boots.
"Fern?" Frieren asked, pausing.
"Mistress Frieren..." Fern whispered, her voice shaking. "His mana... it has no bottom. It's limitless."
The man turned around, scratching the back of his head with a sheepish grin. "Mana? Oh, you mean chakra. Yeah, I've got a bit of a surplus. Name's Naruto Uzumaki, by the way. Make yourselves at home."
The inside of the cabin was a bizarre museum of a forgotten era. Above the fireplace, framed pieces of parchment—preserved perfectly by those strange ink seals—held moving and still images. Stark stared at a picture of a beautiful woman with pale lavender eyes, a boy who looked just like Naruto, and a little girl with a sunflower in her hair. Another photo showed three young kids and a silver-haired man with a mask. And there was a whole row of photos showcasing a range of individuals.
Next to the photos were stacks of ancient, spiraling scrolls, and right beside them, a perfectly preserved stack of little orange books titled Icha Icha Paradise, which Frieren was already squinting at curiously.
"Whoa, it’s so warm," Stark said, wandering toward a low table. He noticed a cushion near the fireplace where a tiny, chubby, nine-tailed orange fox was resting its head on its paws. Its eyes were closed, completely still.
"Oh, wow," Stark smiled, the tension leaving his shoulders. "For a scary guy, he’s got a pretty cute taste in toys."
Reaching down, Stark patted the soft fur on the fox's head.
The fox's eyes snapped open—slit red eyes filled with ancient malice.
CHOMP.
"GAAAAAH!" Stark shrieked, flailing his arm wildly as the tiny fox clamped its jaws onto his wrist, refusing to let go.
"Ow, ow, ow! What kind of plushie does that?!" Stark wailed, spinning in circles.
The fox released him, landing gracefully on the cushion. It sat back on its hind legs, licking its paw with absolute superiority. "Plushie?" the fox snorted, its voice deep, echoing, and hilariously small. "The brat didn't ask for permission. You're lucky I didn't take the whole arm. Kids these days have zero respect for their elders."
Stark went paler than the snow outside. "THE TOY JUST TALKED!"
"Kurama, I told you to stop biting the guests!" Naruto shouted from the kitchen. "Bad fox!"
While Stark panicked, Fern remained frozen, her eyes darting around the room. The fox wasn't the only one.
Curled directly in front of the hearth was a tiny cat made of flickering blue flames, purring softly. Sitting casually on the dining table was a tiny, majestic red gorilla eating a slice of apple, standing next to an elegant white horse-dolphin creature that puffed steam from its nostrils.
Through the back window, Stark spotted several gigantic creatures relaxing in the hot springs.
He decided immediately that he did not want details.
Over in the indoor greenhouse, Frieren was mesmerized by a six-winged armored beetle hovering over the winter flowers, glowing with a soft green light.
But Fern was currently locked in a staring contest.
Sitting on a shelf next to the ancient scrolls was a chubby, sandy raccoon. Its arms were crossed, and its star-shaped pupils were glaring directly at her. Shukaku was completely bored, but the sheer, chaotic pressure radiating off the tiny sand creature made Fern break into a cold sweat. ‘Does it want to kill me?’ she thought, her grip tightening on her staff. ‘Or does it just want a snack?’
"Alright, everyone!" Naruto's voice boomed, shattering the tension. He walked out of the kitchen carrying a massive tray of steaming bowls. "Food's ready! Get over here before Kurama eats it all!"
"I heard that, brat!" Kurama barked from his cushion.
Naruto sighed, noticing the three travelers still standing awkwardly. "Hold on a sec, let me grab some extra seats." He ducked into a storage closet, emerging a moment later carrying three sturdy wooden chairs. He set them around the massive table with a bright, welcoming grin. "Sit down, sit down! Eat before it gets cold."
Stark, rubbing his wrist, took a seat far away from the orange fox. Fern sat stiffly, keeping one eye on the raccoon. Frieren took her seat with mild curiosity.
Once the humans and the nine miniature beasts were gathered around the table, Naruto clapped his hands together.
"Itadakimasu!" Naruto and the Tailed Beasts chimed in perfect unison.
In front of the travelers sat large, steaming bowls of ramen. The rich, aromatic broth was topped with perfectly sliced pork, a soft-boiled egg, and tightly coiled noodles. Stark stared at it, poking a noodle with his chopsticks.
"Uh... Frieren?" Stark whispered. "What kind of stew is this?"
"I've never seen anything like it in the Central Lands," Fern murmured, though the savory scent was making her stomach rumble betrayingly.
Stark took the plunge. He scooped up a massive spoonful of noodles and broth, blowing on it before shoving it into his mouth.
His eyes widened to the size of dinner plates. A wave of pure, culinary euphoria washed over his face. "OH MY GOD! THIS IS AMAZING!" Stark shouted, digging back in immediately. "It’s savory, it’s salty, the meat just melts—Mister Naruto, you're a culinary wizard!"
Fern took a small, polite bite. Her stoic facade cracked immediately, her cheeks flushing a soft pink. "It... it is acceptable," she said, trying to maintain her composure. "In fact, it is exceptionally well-balanced. Thank you for the meal, Mister Naruto."
Frieren slowly sipped the broth, her elf ears perking up in delight. She looked at Naruto. "Naruto... Can I have the recipe? I can trade you a spell that turns sweet grapes sour."
Naruto let out a hearty, booming laugh, rubbing the back of his head. "Sorry, the secret recipe stays with me!"
Suddenly, a tiny fist slammed against the wood.
"Hey! Why does the fox get three pieces of pork?!" Shukaku yelled, pointing his sandy paw at Kurama’s bowl. "I’m the One-Tail, I deserve the largest bowl!"
"Shut up, sand-rat," Kurama sneered, curling his nine tails protectively around his food. "You don't even have a stomach, you're just sand! You’ll ruin the broth. The strongest gets the best toppings."
"I need the carbs for training!" Son Goku yelped as one of Gyuki’s tiny tentacles tried to stealthily swipe Kokuo’s soft-boiled egg from across the table.
Matatabi gracefully leapt from beside the fireplace onto the bench behind Naruto.
Then, with complete confidence, she began climbing onto his shoulders.
Naruto sighed immediately.
“Matatabi.”
“It is cold.”
“You are literally made of fire.”
“And yet you are warmer.”
Before Naruto could protest further, the two-tailed cat curled directly across his lap, blue flames flickering lazily around his sweater.
Across the table, Kurama’s ears flattened.
“…Back off.”
Matatabi didn’t even open her eyes.
“No.”
“That is MY jinchūriki.”
Fern nearly dropped her chopsticks again.
Son Gokū barked out a loud laugh.
“You’re still saying that?”
“I was first,” Kurama growled.
From the other side of the table, Isobu slowly lifted his head from his plate.
“Technically,” the spiky turtle rumbled calmly, “Naruto is all of our jinchūriki now.”
Kurama looked personally offended by the concept.
“That changes nothing.”
“It literally changes everything,” Gyūki muttered.
Naruto facepalmed at the ancient beast’s childish behavior.
“You guys have had this argument for like hundreds of years.”
“And I remain correct,” Kurama said instantly.
And then Kurama launched himself at Matatabi, apparently deciding he needed to enforce justice personally.
"Hey!" Naruto yelled, slapping a wooden spoon down on the table with enough force to rattle the bowls. "If you guys knock over the broth, nobody gets seconds! Eat nice or you're sleeping outside in the blizzard!"
The ancient beasts immediately grumbled, but they settled down, angrily chomping on their noodles.
Stark looked at the bickering, magical creatures, then at the impossibly powerful, immortal man happily schlurp-ing his noodles. He looked over at Fern, whose terror had finally melted into bewildered amusement, and then at Frieren, who was just happily eating her food.
It was the strangest, most terrifying cabin in the Northern Lands, but as the fire crackled and the storm raged outside, it was also the warmest.
For a few blessed minutes, the cabin became quiet except for the sounds of slurping noodles and crackling firewood.
Stark was halfway through his second bowl before the peace finally shattered.
“This is favoritism.” Shukaku declared.
Naruto didn’t even look up.
“No, it isn’t.”
“Yes, it is,” Shukaku snapped, pointing an accusatory paw across the table. “Kurama has had the largest bowl for the last three centuries.”
Kurama continued eating calmly.
“As he rightfully should.”
Shukaku slammed both paws onto the table.
“It is MY turn.”
“You had your turn.”
“That was four hundred years ago!”
“Exactly. Recently.”
Fern nearly inhaled a noodle.
“That counts as recent to you people?”
“Very,” Frieren answered quietly before sipping her broth.
Shukaku puffed up angrily.
“I demand equal portion distribution.”
Kurama finally glanced at him lazily.
“You are three feet tall.”
“That is irrelevant to the principle of the matter!”
“You physically cannot finish that much food.”
“I CAN IF GIVEN THE OPPORTUNITY.”
Naruto pinched the bridge of his nose.
“Dear god, I do NOT want to restart the Great Ramen Incident,” Naruto said, looking at each Tailed Beast with a terrifying glare. “It took us a whole century to get things going again!”
Stark froze.
“…The what?”
Every bijuu except Kurama looked away simultaneously.
“…We do not speak of it,” Gyūki muttered.
Frieren paused, her chopsticks hovering inches from her mouth. Her eyes gleamed with quiet curiosity.
“A century to get things going again?” she repeated. “Did you accidentally seal a rare strain of wheat behind a multilayered barrier? Or destroy legendary cultivation soil?”
Naruto winced.
“...Let’s just say a certain oversized fox and a certain sand-rat got into an argument over the last naruto cake, a mountain disappeared, and the ecosystem needed about a century to recover.”
“It was a tactical strike,” Shukaku huffed.
“You missed me and destroyed the pantry, idiot,” Kurama snapped.
“That pantry was in the blast radius.”
“Because YOU AIMED AT THE HOUSE.”
“Alright, enough history lessons,” Naruto interrupted quickly, clapping his hands together. “The storm isn’t dying down anytime soon, so you guys can stay the night. We’ve got plenty of blankets.”
"Thank you very much," Fern said, bowing her head politely, though her eyes involuntarily drifted back to the tiny sand-raccoon who was still muttering curses under his breath about the uneven distribution of pork slices.
"Yeah, seriously, thanks man," Stark added, letting out a breath he felt like he’d been holding since they crossed the mountain ridge. "I don't think my toes would've made it to Außerst."
"Don't sweat it," Naruto grinned, standing up and stacking the empty ramen bowls with practiced ease. "I don't get many visitors up here. Honestly, the noise is kind of nice for a change."
Frieren watched him quietly as he walked toward a blank section of the wooden wall. He didn't open a closet. Instead, he casually bit the tip of his thumb, smeared a tiny drop of blood across an intricate, spiraling ink crest painted onto the wood, and clapped his palm against it.
Poof.
With a soft cloud of white smoke, three thick, incredibly fluffy futons and a mountain of heavy winter blankets materialized out of thin air, tumbling onto the floor.
Frieren’s elf ears twitched. She immediately stood up, abandoning her empty bowl to inspect the wall where the ink crest was drawn. She poked the wood with a slender finger.
"There was no mana flow," Frieren murmured, her eyes wide with academic fascination. "Usually, spatial transition magic requires a massive, stable magic circle and a continuous flow of mana to pull objects from a pocket dimension. But this... the energy is completely stagnant until your hand touches it. It's perfectly compressed."
"Oh, Fuinjutsu?" Naruto tossed a thick blanket to Stark, who caught it with a grunt. "Yeah, it's an old family trait. My clan used to be pretty famous for it. You basically write a formula to lock reality into a specific piece of paper—or wood, in this case. It keeps the food hot, the blankets dry, and the lights running without needing to constantly pump energy into them."
"A formula that locks reality..." Frieren traced the ink lines with her fingernail, her mind clearly racing with the possibilities. "Can it lock the flavor of a bakery-fresh tart forever?"
"Uh, yeah, pretty much," Naruto laughed, rubbing the back of his head. "I've got some scrolls in the back with ingredients that have been fresh for about seven hundred years."
"Mistress Frieren, please do not bother our host with your strange obsession with sweets," Fern chided gently, already taking one of the futons and neatly spreading it out across the floor. "We are guests."
Within an hour, the cabin settled into a quiet, post-meal rhythm. The Tailed Beasts, finally full and exhausted from their various arguments, began finding their respective sleeping spots.
Matatabi remained curled tightly on the rug by the fireplace, her blue flames dimming to a gentle, hypnotic ember glow. Saiken had slithered back out toward the hot springs, while Chomei perched herself softly on the rafters above, her iridescent wings folding over her body like a cocoon.
Stark carefully laid his futon down, making absolutely sure he was as far away from the fireplace cushion as humanly possible. He glared warily at the orange fox, who was currently yawning, stretching its nine tails, and curling into a tight, fluffy ball.
"Hey, kid," Kurama muttered, opening one slit red eye to look at Stark.
Stark froze mid-air, a blanket clutched to his chest. "Y-Yes, sir?"
"If you snore, I'm biting the other wrist."
"I won't breathe! I swear!" Stark hissed, immediately diving under his covers and laying perfectly still.
Fern sat on the edge of her futon, quietly brushing out her purple hair. Her eyes kept wandering over to the mantle above the fireplace, specifically to the long row of photographs. From a distance, she could see dozens of faces—some smiling proudly in strange armor, others laughing with their arms thrown around a younger version of Naruto. Every single one of them looked incredibly vibrant, full of life, and entirely human.
And yet, none of them were here.
Frieren walked over to the mantle, standing silently in front of the photos. She looked at the picture of the kind-eyed woman with the dark hair, then at Naruto, who was currently sitting at the kitchen table, quietly wiping down his wooden spoon.
"They're all gone, aren't they?" Frieren asked softly.
Naruto’s hand paused for a fraction of a second. He didn't look up, but a small, incredibly gentle smile touched his lips. "Yeah. A long time ago."
"How long have you lived in these mountains?"
"I lost count after the first three thousand years," Naruto said, his voice dropping into a quiet, raspy tone that carried the immense weight of the eras he had outlived. "The world down there... it changed. The villages I knew turned into cities, the cities turned into ruins, and then new people built over those ruins. After a while, I realized I didn't really fit into the picture anymore."
“What…” Frieren murmured in disbelief.
Three thousand years.
Even by elven standards, that was ancient.
Fern stopped brushing her hair, listening intently. She had spent her whole life learning about Frieren's detached view of time, but hearing it from a man who looked no older than Stark's older brother was jarring.
"Frieren tells us that humans live in the blink of an eye," Fern said quietly, her voice tentative. "Is that why you stay up here alone?"
Naruto finally set the spoon down and looked over at them, his blue eyes reflecting the dim glow of the fireplace. The loud, boisterous ninja who had just threatened to throw ancient beings out into a blizzard vanished, replaced by a solitary immortal.
"When you love people as much as I do, watching them grow old and fade away... it tears a piece out of you every single time," Naruto said softly, glancing at the photo of his children. "I used to think I could just keep making new friends, keeping the bond alive. But eventually, the grief gets heavy. You start to realize that the kindest thing you can do for yourself—and for them—is to just be a passing shadow. You help them when they're in trouble, you give them a hand, and then you move on before they learn your name."
He stood up, stretching his arms over his head until his back popped, breaking the heavy solemnity of the room with a sudden, easygoing grin.
"But hey! You guys don't need to worry about any of that tonight. You've got an exam to pass in Außerst," Naruto chuckled, walking toward his own sleeping quarters in the back. "Get some sleep. The seals on the walls will keep the storm out, and I'll make sure Shukaku doesn't try to draw on your faces while you're asleep."
"Goodnight, Naruto," Frieren said, her eyes lingering on his retreating back before turning back to the glowing ink symbols on the wall.
Frieren lingered silently by the mantle.
The world Naruto described felt painfully familiar.
As the lanterns dimmed and the cabin fell into darkness, the only sound left was the furious howling of the blizzard outside, completely powerless against the warmth inside.
