The Senju compound had witnessed many terrifying displays of power. It had seen the cracking of stone under immense weight, the blossoming of Senju wood, and the clash of the village's strongest martial artists.
But it had never witnessed anything quite as strange as the current situation taking place on the central stone slab.
"I WILL FEAST ON YOUR BONES!" the tiny, nine-tailed fox shrieked, his voice lacking the booming resonance of a mountain-shattering demon, instead sounding like a shrill bird. "I WILL TEAR THIS VILLAGE DOWN TO ITS FOUNDATIONS! I WILL RAIN FIRE UPON YOUR DESCENDANTS!"
The tiny manifestation of the Nine-Tails paced back and forth across the stone, his nine fluffy tails swishing furiously behind him. Every time he stomped his small, clawed foot to emphasize a threat, the soft padding of his paw entirely undermined the malice of his words.
Nanami Kento stood a few paces away, his arms crossed over his chest. He watched the miniature harbinger of destruction throw his tantrum with a look of mild, detached amusement.
"The volume is impressive, given the lack of lung size," Nanami observed, leaning slightly toward his wife.
Tsunade had both hands covering her mouth, her shoulders shaking. She was a hardened kunoichi, a woman who punched through solid iron and faced down enemy battalions without a flinch. Yet, seeing the entity that had terrorized the world reduced to the size of a small hound was testing the absolute limits of her composure.
"He's..." Tsunade choked back a laugh, a tear escaping the corner of her eye. "He's so fluffy, Kento. Look at his little teeth. He looks like he's trying to be scary, but he just looks... cute."
"DO NOT USE THAT WORD!" the fox roared, spinning around to bare his needle-like fangs at her. "I AM THE EMBODIMENT OF HATRED! THE STRONGEST OF THE NINE! I AM TERROR GIVEN FORM!"
"Terror given form," Nanami repeated dryly, uncrossing his arms and rubbing his chin. "Tsunade is correct. Your appearance completely negates the threat level. We cannot simply call you the 'Nine-Tails' anymore. It sounds entirely too grand for something that could comfortably fit inside a ninja pouch."
The fox's ears flattened against his head, his red fur bristling. "My title is my right! You will address me with the fear I command, human!"
"We should give him a name," Nanami continued, completely ignoring the demon's protests. He looked at Tsunade. "If he is going to be living in our house, a proper name is required."
Tsunade finally let her hands drop from her mouth, a wicked, teasing grin spreading across her face. "A name? Well, we should figure out what we are dealing with first. Is he a male or a female? I have never actually read any historical texts detailing the nature of a chakra beast."
Nanami tilted his head, a thoughtful expression crossing his face. "A valid question. Understanding his nature is the first step. Let us find out."
Nanami took a deliberate step forward, extending his large, calloused hands toward the tiny fox.
The Nine-Tails froze. The furious pacing stopped instantly. His slit, demonic eyes widened in absolute horror as he realized what the human intended to do.
"Wait," the fox squeaked, scrambling backward on the stone slab. "What are you doing? Stay back! Do not touch me with those filthy hands!"
"Do not struggle," Nanami said in a calm tone, taking another step. "I am simply going to lift you up to inspect your underside. It will take only a second."
"UNDERSIDE?!" the Nine-Tails shrieked in absolute panic.
The ancient demon, a being composed of pure, concentrated malice, turned tail and bolted. He scrambled off the edge of the stone slab, his tiny claws slipping frantically against the smooth surface before he hit the ground and darted behind Mito Uzumaki's legs.
"We do not have genders!" the fox yelled from behind the safety of the Uzumaki matriarch's kimono, his tails wrapping protectively around his own body. "We are masses of sentient chakra! We do not reproduce! Do not violate my dignity, you absolute brute!"
Nanami paused, lowering his hands. He let out a deep, rumbling laugh that echoed off the stone walls of the basement. Tsunade completely lost her battle with composure, bending over and laughing so hard she had to clutch her stomach.
Even Mito, who had borne the agonizing weight of the fox for decades, covered her mouth with her sleeve, her shoulders trembling with silent, joyous mirth. The oppressive, burning friction in her core was gone, replaced by a light, airy freedom she had not felt since the days of the Warring States.
"Very well," Nanami conceded, a playful glint in his sea-green eyes. "Gender-neutral it is. Any suggestions?"
Tsunade wiped her eyes, taking a deep breath to steady herself. "If he is made of fire and anger, we could call him 'Aka'. Or maybe 'Katsu', since he is always shouting."
"Too simple," Mito suggested gently, stepping away from the fuming fox. "He is a creature of the forest, originally. Perhaps something elegant. 'Tama', for the jewel-like quality of his chakra?"
"I AM NOT A HOUSE CAT!" the fox bellowed, stepping out from behind Mito's robes. "I will not answer to 'Tama'! I will incinerate the first person who calls me 'Aka'! If you must label me, call me the Destroyer! Call me the Crimson Death!"
"Those are titles, not names," Nanami pointed out logically. "They are too long. A name should be short, so it is easy to call out in battle."
Nanami tapped his chin, his expression turning thoughtful. He looked down at the furious little beast, who was currently trying to puff out his chest to look intimidating.
"How about..." Nanami started, his voice dropping into a calm, resonant tone. He looked directly into the fox's slit eyes. "Kurama."
The effect was instantaneous.
The tiny Nine-Tails stopped breathing. His jaw snapped shut with an audible click. The nine tails that had been swishing wildly froze perfectly still in the air.
Inside the fox's ancient, malevolent mind, his thoughts ground to an absolute halt. The sheer impossibility of the word hit him harder than the golden aura had.
Kurama.
That was his name. His true name. The name given to him by the old man—Hagoromo Otsutsuki, the Sage of Six Paths—centuries ago, before the world descended into endless war. Only the other Tailed Beasts knew that name. Only the Sage's direct sons, Ashura and Indra, had ever heard it. Hashirama Senju had not known it. Madara Uchiha, who had dominated him with the Sharingan, had certainly not known it.
How did this mortal, a mere human born generations after the era of the gods, know his true name?
Kurama stared at Nanami. He searched the human's sea-green eyes for a sign of the Sage, for a sign of the ancient reincarnation cycle. But he saw nothing of Ashura or Indra in this man. He saw only a terrifyingly dense spirit, an unnerving calm, and a faint, knowing smirk.
A coincidence, Kurama forced himself to rationalize, his tiny heart beating frantically. It must be a random alignment of sounds. Humans make up thousands of names. It is possible he simply guessed a sound combination that matched.
If he reacted, if he confirmed that this was his true name, he would be conceding a piece of his deepest self to the human who had just threatened to inspect his underside.
Kurama forced his face into a mask of pure, stubborn indifference. He turned his head away, letting out a small, dismissive huff of air.
Nanami watched the internal struggle play out across the fox's face. He could practically see the thoughts turning, the denial solidifying. Nanami kept his face perfectly neutral, though internally, he was highly amused by the sheer confusion he had just inflicted upon a legendary entity.
"Well," Nanami said, breaking the silence and turning back to his wife and her grandmother. "He has stopped shouting. Silence is agreement. It seems he finds the name acceptable. From now on, his name is Kurama."
"Kurama," Tsunade tested the word, nodding slowly. "It sounds strong. A bit grumpy. It fits him perfectly."
Mito smiled, placing a gentle hand on her stomach. The seal was still there, but the burden was gone. "Kurama it is. Now, let us leave this dark room. I wish to see the sky, and I believe my great-grandson is likely waking up from his nap."
Nanami, Tsunade, and Mito ascended the stairs, with the newly named Kurama trotting reluctantly behind them. He refused to be carried, snapping his tiny jaws at Tsunade when she offered, choosing instead to walk with exaggerated, prideful steps that looked entirely ridiculous given his size.
They entered the living room. The sun had set, and the glow-moss lanterns cast a warm, inviting light over the tatami mats. In the corner, sleeping peacefully in a sturdy wooden crib that Nanami had carved by hand and reinforced with absolute defensive seals, was Akira.
Tsunade immediately walked to the crib, her tough exterior melting into a soft, devoted smile as she looked down at her son. Mito went to the tea table, pouring herself a cup with hands that no longer trembled from chronic fatigue.
Kurama hopped up onto a plush, red sitting cushion near the corner of the room. He curled into a tight ball, wrapping his nine tails around his face. He intended to sulk. He intended to plot the gruesome demise of the golden-eyed human. He intended to ignore the indignity of sitting on a comfortable cushion in a human dwelling.
The front doors of the compound slid open with a loud, distinct clatter.
"WE'RE HERE, DATTEBANE!"
The shout echoed down the hallway. Footsteps—two pairs, moving with excessive speed and no stealth—pounded across the wooden floorboards.
The sliding screen door to the living room was thrown open violently.
Nawaki Senju tumbled into the room, followed closely by Kushina Uzumaki. The two children were covered in dirt, sporting small scrapes on their cheeks from what was undoubtedly a chaotic afternoon at the Academy training grounds.
"Kento-niichan! Tsunade-neechan!" Nawaki beamed, holding up a wooden kunai. "I hit the target three times today! I'm getting closer to Hokage level!"
"I hit it five times, ya know!" Kushina corrected loudly, placing her hands on her hips and sticking her chin in the air. "You're still too slow, Nawaki! You need to focus your chakra faster!"
"I am focusing! You just throw too hard!"
From the red cushion in the corner, a low, irritated growl vibrated.
Kurama uncoiled slightly, opening one slit red eye to glare at the two children who had just shattered his brooding silence.
"Quiet," Kurama snapped, his high-pitched voice carrying a surprising amount of venom. "Your voices are grating. The sound is offensive to my ears. Cease this pointless noise immediately."
Nawaki and Kushina froze.
They looked around the room, confused. They looked at Nanami, who was standing by the window. They looked at Tsunade by the crib. But neither of them had spoken.
Then, Kushina's sharp violet eyes tracked the sound to the corner.
She blinked.
Nawaki followed her gaze. His jaw dropped.
Sitting on the cushion was a creature with red fur, long ears, and an excessive number of tails.
"Whoa," Nawaki breathed, walking slowly toward the cushion, completely ignoring the danger. "What is that? Tsunade-neechan, did you get a new ninja beast?"
"A ninja beast?" Kushina asked, her eyes sparkling with curiosity as she stepped up beside Nawaki. She leaned down, inspecting the fox closely. "It looks like a tiny dog. Or a very angry squirrel. Look at how fluffy it is, dattebane!"
Kurama's eye twitched violently.
He was the Nine-Tails. He was the disaster that flattened forests and boiled oceans. He was not a dog. He was certainly not a squirrel. He wanted to roar. He wanted to declare his true, terrifying identity to these ignorant whelps and watch them cower in fear.
But then he looked at Nanami, who was watching the interaction with a calm expression.
If Kurama declared his identity now, he would be admitting that the great and terrible Nine-Tails had been reduced to the size of a household pet. He would be admitting that he had been forcefully extracted and turned into a literal pressure seal by a human. The humiliation of being called a squirrel was profound, but the humiliation of the world knowing the Nine-Tails was currently sitting on a plush red pillow in the Senju living room was absolutely unbearable.
His pride demanded silence. He clamped his jaws shut, swallowing his rage, vowing to incinerate these children the moment he regained his true mass.
Tsunade, catching on to the dynamic instantly, let out a soft chuckle. She walked over, resting a hand on Nawaki's shoulder.
"Yes, Nawaki," Tsunade lied smoothly, a mischievous spark in her golden eyes. "We acquired a new ninja beast today. But you must be careful; he is a little grumpy. His name is Kurama."
"Kurama," Kushina tested the name, grinning widely. She leaned in closer, until her nose was only inches away from the fox's snout. "He doesn't look very tough. His paws are so small! Are you a tracker beast? Can you smell enemies?"
"Do not insult my sense of smell, you loud, red-haired nuisance," Kurama snarled, baring his tiny fangs. "I can smell the dirt on your face from across the compound. Step back before I bite your nose off."
Kushina did not step back. Instead, her fiery Uzumaki temper flared instantly.
"Who are you calling a nuisance, you oversized furball?!" Kushina shouted back, pointing a finger directly between his eyes. "I am Kushina Uzumaki! I'm going to be a great kunoichi! You're just a tiny pet with too many tails! You look like a strange dust mop, ya know!"
"A dust mop?!" Kurama stood up on the cushion, his fur bristling until he looked twice his actual size, a sphere of pure, angry red fluff. "I am a creature of power! I have crushed men beneath my heel! You are a speck of dust in the wind of my existence! I will—"
"You will what? Bark at me?" Kushina mocked, placing her hands on her knees and leaning down to match his height. "You're so small I could put you in my pocket! Let's see you crush something right now, shorty!"
"Shorty?!" Kurama shrieked, his mind reeling from the utter disrespect. No human had ever spoken to him this way. They either prayed to him, fought him with armies, or bound him in iron. They did not call him a dust mop. "I will show you destruction, tomato!"
"TOMATO?!" Kushina's face turned as red as her hair. The one insult she absolutely refused to tolerate. She rolled up her sleeves. "That's it! I'm going to tie all your tails into a knot, you stupid raccoon!"
"Try it, brat! You will lose your fingers!"
"Bring it on!"
Nawaki stood between them, watching the shouting match.
Kurama was a being composed entirely of ancient, unfiltered malice. Over the centuries, he had cultivated a very specific, carefully ordered hierarchy of hatred within his mind.
At the absolute summit sat Madara Uchiha, the man who had dared to enslave his will with those cursed eyes. Second was Hashirama Senju, the hypocrite who had pinned him to the earth with massive wooden hands and declared him too dangerous to roam free. Third was Mito Uzumaki, the woman who had bound him in a dark, suffocating cage of flesh and iron seals for decades.
But as he stared at this loud, red-haired child who was currently threatening to treat his majestic, divine tails like pieces of common rope, the hierarchy shifted violently. Kushina Uzumaki was rapidly ascending the list. In fact, in this exact moment, she was aggressively rivaling Madara Uchiha for the top position.
Kurama had finally reached his limit. The utter disrespect from these two human children was too much to bear. His ancient, demonic pride overrode his sense of caution.
"I WILL ERASE YOU FROM THIS EARTH!" Kurama roared.
He hopped off the cushion, planting his tiny paws firmly on the tatami mat. He opened his small jaws wide. Deep in his throat, he began to gather his chakra, attempting to mix the positive black and negative white energy into the ultimate weapon of the Tailed Beasts.
Tailed Beast Bomb! he declared in his mind.
Kushina and Nawaki paused, watching the fox open his mouth.
A faint spark of red and blue chakra gathered between Kurama's needle-like teeth. He pushed with all his might, straining to compress the devastating energy that could vaporize mountains.
Phbbbt.
Instead of a cataclysmic sphere of destruction, a small, pathetic puff of black smoke coughed out of Kurama's mouth. It drifted through the air and dissipated harmlessly against Kushina's nose, making her sneeze.
Kurama froze, his mouth still open. He stared at the empty air where his ultimate attack should have been. The realization of his severely restricted chakra output crashed down on him.
Kushina blinked, rubbing her nose. "Did he just... burp smoke?"
Nawaki tilted his head. "I think he's sick, Kushina. Or maybe he swallowed a bug."
Kurama's face flushed with a level of humiliation he had never experienced in his centuries of existence. He slowly closed his mouth, his ears drooping in absolute defeat.
Tsunade, watching from by the crib, let out a loud snort. She crossed her arms and smirked down at the sulking demon.
Nanami had already told her that the fox's threat level was currently that of an angry house cat, and seeing the mighty Nine-Tails fail to produce anything more than a soot cloud was the most entertaining thing she had witnessed all week.
Nanami watched the scene unfold from his place by the window.
A normal observer might have intervened to stop a child from provoking a being composed entirely of hatred. But Nanami Kento operated on the principles of preserving strength and tactical patience.
Kurama has too much pent-up anger from his confinement, Nanami noted, crossing his arms and settling comfortably against the wall. Kushina has too much energy from her youth and bloodline. By allowing them to argue, they will tire each other out without destroying the living room.
It was a perfectly balanced outcome.
"Should we stop them?" Mito asked softly from the tea table, though she was smiling behind her cup.
"No," Nanami replied, watching Kushina threaten to use Kurama as a scarf, while the ancient demon weakly threatened to bite her ankles. "This is excellent training. It builds character in the child and humility in the beast. We will intervene only if teeth are deployed."
Tsunade walked over and leaned against Nanami, wrapping an arm around his waist as they watched the chaos in the corner.
"You're a terrible influence, Kento," she murmured, resting her head on his shoulder. "You're going to let a small girl fight a grumpy pet."
"I am fostering communication," Nanami corrected smoothly, wrapping his arm around her shoulders. "Besides, my money is on Kushina. She has more stamina."
As the shouting match between the fiery Uzumaki girl and the humiliated, tiny god of destruction continued to echo through the Senju household, Nanami let out a quiet sigh of contentment.
