Sunday morning in Konoha was usually a time for rest. For Nanami Kento, however, it was a time for preparing the performance review.
He stood in front of his mirror, adjusting the collar of a white button-up shirt he had specifically requested his mother to buy. It wasn't the standard Academy gear. It was crisp, clean, and projected an image of competence. He paired it with dark trousers and clean sandals.
"You look very handsome, Kento!" Haruka gushed, smoothing down his hair. "Are you sure this is just a lunch? It looks like you're going to a meeting."
"In a way, Kaa-san, it is," Nanami murmured, checking his reflection for any imperfections. "I am meeting with the board of directors."
"The board of...?" She blinked, confused.
"The Senju family. Specifically, Mito Uzumaki."
Haruka gasped, her hand flying to her mouth. "Lady Mito?! Oh, Kento! You must be polite! You must eat everything on your plate! Don't stare at her diamond seal!"
"I am aware of the protocol," Nanami assured her. "I will be the picture of civilian deference."
He left the bakery at 11:30 AM sharp. He calculated the walking speed required to arrive exactly five minutes early—punctual, but not desperate.
As he approached the Senju compound—a massive, walled estate that occupied a prime chunk of real estate near the Hokage Rock—he saw a familiar figure waiting at the gates.
Tsunade was pacing. She wore a formal kimono in pale green with pink cherry blossom patterns. It looked expensive and uncomfortable. She was fidgeting, kicking at a pebble.
"Yo," Nanami called out, raising a hand.
Tsunade stopped pacing. She looked relieved. "You actually came. I thought you might chicken out."
"I considered it," Nanami admitted honestly. "Strategically, entering the den of the village's most powerful clan is a high-risk maneuver. But the potential ROI—Return on Investment—is too high to ignore."
"Stop talking like a banker," Tsunade grumbled, grabbing his arm and dragging him toward the gate. "Come on. My dad is annoying, my mom is waiting, and Grandma is... well, Grandma. Just don't say anything stupid."
"I specialize in not saying stupid things. It's my brand."
They walked through the compound. It was more of a park with buildings in it, rather than a house. Koi ponds, manicured gardens, and ancient wooden structures that smelled of history and cedar.
They reached the main house. Tsunade slid the door open.
"I'm back! I brought him!"
The living room was spacious, overlooking a zen garden. Three people were waiting.
Sitting on the left was a woman with kind eyes and brown hair tied back in a practical bun—Kaede Senju, Tsunade's mother.
Sitting in the center, looking like a mountain in human form, was a man with tanned skin, messy brown hair, and a jawline that could cut glass—Daichi Senju, Tsunade's father and the son of Hashirama.
And on the right, sitting on a cushion with perfect posture, was Mito Uzumaki.
Nanami felt it instantly.
It wasn't a killing intent. It wasn't chakra pressure. It was just... weight. The air around her felt denser. She wore a white kimono with the Uzumaki swirl on the back, and her red hair was done up in the traditional buns with tag-shaped hair clips. The diamond seal on her forehead violet and pristine.
She looked at him. Nanami felt like an X-ray machine was scanning his soul.
Protocol 1: Respect, Nanami engaged.
He walked to the center of the room and bowed deeply—a perfect forty-five degrees.
"Good afternoon," Nanami said, his voice steady. "I am Nanami Kento. Thank you for inviting me into your home."
"Oh, he's polite!" Kaede smiled, clearly charmed. "Come in, Kento-kun. Sit, sit."
Nanami sat in seiza on the provided cushion, keeping his back straight.
"So," Daichi leaned forward, resting his elbows on his knees. He grinned, and Nanami saw where Tsunade got her mischievous streak. "You're the kid, huh? The one who finally got my little Tsuna to take training seriously?"
"Tou-san!" Tsunade shrieked, her face turning red. "I always take training seriously!"
"Hah! You used to sneak out of kata practice to play dice with the gardening staff," Daichi laughed. "But lately? You're in the backyard sweating until sunset. 'I have to catch up,' you said. 'I can't lose to him,' you said."
"I never said that!"
The parents laughed. Even Mito's lips quirked upward slightly.
"It is an honor to facilitate healthy competition," Nanami said diplomatically. "Tsunade is a talented sparring partner."
"Sparring partner," Daichi chuckled. "Right. Anyway, welcome. Any friend of Tsuna is welcome here. Your parents run the bakery on Main Street, right? The melon pan there is dangerous. I gained two kilos last month because of it."
"I will convey your compliments to my father," Nanami nodded. "He considers sugar a distinct food group."
The conversation flowed easily for a few minutes—standard small talk designed to put a guest at ease. But Nanami remained alert. He knew the real interview hadn't started yet.
Then, the air shifted.
Mito Uzumaki set down her teacup. The sound of porcelain hitting wood was soft, yet it silenced the room instantly.
"Tsunade tells me," Mito began, her voice sounding like wind chimes—clear, beautiful, and old, "that you have an interest in Fuinjutsu."
Nanami turned his head slightly to meet her gaze. He didn't flinch. "Yes, Mito-sama."
"Why?"
It was a simple question. But coming from the greatest Sealing Master alive, it was a trap.
Why? Nanami thought. Because it's powerful? Because it's versatile? Because I want to cheat?
He looked at her eyes. They were dark, endless pools.
She's a sensor, Nanami realized. An Uzumaki sensor. The Mind's Eye of the Kagura. She can sense emotions. She can sense deception. If I give her a generic, textbook answer about 'protecting the village', she will know I am lying. She will dismiss me as a sycophant.
Honesty. Calculated honesty was the only play.
"Because it is the source code," Nanami said.
Mito blinked. "Source code?"
"Ninjutsu," Nanami explained, using his hands to gesture, "is like running a program. You input chakra, you perform hand signs, and the universe executes a specific command. Fireball. Water Dragon. Shadow Clone."
He paused, gathering his thoughts.
"But Fuinjutsu... Fuinjutsu is the language in which the command is written. It deals with the fundamental logic of reality. Space. Time. Storage. Binding. If Ninjutsu is playing the game, Fuinjutsu is rewriting the rules of the game."
He looked directly at her.
"I do not wish to merely play the game, Mito-sama. I wish to understand the rules so I can ensure the game... works in my favor. It is the ultimate form of efficiency."
Silence stretched across the room.
Daichi looked confused. Kaede looked impressed. Tsunade looked at him like he was speaking an alien language.
Mito stared at him for a long, agonizing moment. Then, a slow smile spread across her face. It wasn't a grandmotherly smile. It was the smile of a scholar finding a rare book.
"Rewriting the rules," she murmured. "An arrogant perspective. But not inaccurate."
She stood up. Her kimono rustled softly.
"How far have you progressed?" she asked.
"I have memorized the introductory scrolls from the Academy library," Nanami replied. "Basic storage, exploding tags, and barrier theory. But I lack the practical application. My ink consistency is poor."
"Come with me," Mito commanded.
She turned and walked toward a sliding door at the back of the room.
Nanami stood up immediately.
Tsunade jumped up too. "I'm coming too!"
Mito stopped. She didn't turn around. "No, Tsunade. You stay here. Help your mother with lunch."
"But Grandma!" Tsunade pouted, crossing her arms. "That's not fair! I found him!"
"Fuinjutsu requires silence," Mito said simply. "And your thoughts are currently too loud."
She slid the door open and stepped into the darkness of the hallway. Nanami followed, offering a small, apologetic shrug to Tsunade before disappearing into the gloom.
Mito's study was exactly what Nanami had imagined.
It smelled of ozone and ink. The walls were covered in hanging scrolls, each one painted with intricate, terrifyingly complex arrays. In the center was a low wooden table covered in brushes, inkstones, and piles of high-grade chakra paper.
Mito walked to the far side of the table and sat down. She gestured for Nanami to sit opposite her.
"The Academy primer teaches the Twelve Radical Seals," Mito said, sliding a blank sheet of paper toward him. She handed him a brush. "Draw the radical for 'Containment'."
Nanami took the brush. He dipped it in the ink.
No hesitation, he told himself. Muscle memory.
He drew. His hand moved with the fluid, practiced motion he had drilled into his clones. The symbol—a boxy, angular character with three swirling anchors—appeared on the paper.
Mito watched his hand, not the paper.
"Acceptable," she noted. "Now, the radical for 'Dispersion'."
Nanami drew it.
"Now, combine them. Create a theoretical array that captures a burst of wind and releases it slowly."
Nanami paused. This wasn't in the book. This was application.
Capture is Containment, he analyzed. Release is Dispersion. But to make it slow... I need a throttle. A timing modifier.
He dipped the brush again. He drew the Containment seal in the center. He drew the Dispersion seal on the outer rim. And in between them, he drew a spiral—a connector he had seen in the library scroll but hadn't fully understood until last night's 'debugging' session.
He finished. He put the brush down.
Mito looked at the paper. She traced the spiral with a manicured fingernail.
"You used a kinetic spiral as a regulator," she observed. Her voice was neutral.
"It seemed logical," Nanami said. "Wind is movement. To slow movement, you force it to travel a longer path. The spiral increases the distance the chakra must travel before exiting."
Mito looked up. Her eyes were gleaming.
"Who taught you that?"
"Logic," Nanami said.
Mito let out a breath she seemed to have been holding. "You have the Instinct. The Uzumaki call it 'Ink Sight'. The ability to see the flow of the seal before it is written."
She reached into her sleeve and pulled out a scroll. It was old, the paper yellowed with age. It was tied with a red cord.
She placed it on the table.
"This is the Intermediate Compendium of Uzumaki Barrier Theory," she said. "It contains the logic for creating localized static barriers. Walls. Cages. Shields."
She slid it across the table to him.
"You have one week," Mito said. "Take it home. Study it. Next Sunday, come back. I will ask you to create a barrier that can withstand a C-rank Jutsu. If you succeed..."
She leaned forward.
"I will accept you as a provisional disciple."
Nanami looked at the scroll. It was heavy. It was priceless. It was exactly what he wanted.
He took the scroll with both hands and bowed his head to the floor.
"I accept the challenge, Mito-sama. I will not disappoint you."
"We shall see," Mito said, standing up. "Now, let us return. If we keep Daichi waiting for lunch any longer, he will start eating the furniture."
Lunch was a less intense, but equally dangerous affair.
Kaede Senju was a master of culinary interrogation. Between bites of grilled mackerel and miso soup, she managed to extract Nanami's entire life story, his favorite colors, his allergies, and his opinions on the current political climate of the Land of Fire.
Nanami navigated the minefield with polite, concise answers, earning approving nods from Daichi.
"He's got a good head on his shoulders," Daichi announced, waving a chopstick. "Not like the kids these days. All flash and no substance. You know, when I was six, Tou-san (Hashirama) threw me into a river to teach me swimming. Sink or swim! That's the Senju way!"
"And you nearly drowned, dear," Kaede reminded him gently.
"But I didn't! Character building!"
After lunch, the dishes were cleared. The atmosphere relaxed.
"So," Daichi said, standing up and stretching. He looked at Nanami. "Tsunade tells me you beat her in a spar yesterday."
The room went quiet. Tsunade froze mid-sip of her tea.
"It was a training match," Nanami corrected carefully. "Tsunade-san is very strong. I merely... redirected her enthusiasm."
"Redirected," Daichi grinned. "I like that word. Diplomacy. But here's the thing, Kento-kun. I'm a simple man. I see a strong kid. I want to see what he can do."
He walked over to the sliding doors leading to the massive backyard.
"Come on. Let's see what you've got."
Nanami looked at Mito. She was sipping tea, watching him with amusement. She wasn't going to stop this. This was part of the audit.
He looked at Tsunade. She looked worried. "Tou-san, he's just a first-year student. Don't break him."
"I won't break him! Just a little stretch!"
Nanami sighed internally. Unpaid overtime. Physical labor. Hazard pay required.
"Very well," Nanami stood up. "I would be honored."
They moved to the garden. It was a large, flat grassy area surrounded by cherry trees.
Daichi stood on one end, rolling up his sleeves. He didn't take a stance. He just stood there, radiating the casual, terrifying confidence of an elite Jonin.
Nanami stood opposite him. He felt small.
He's a Jonin, Nanami analyzed. Son of the First. Likely possesses massive chakra, Earth Release, and Water Release. Physical strength is off the charts. Chance of victory: 0%.
Objective: Impress. Survive. Don't look incompetent.
"Ready when you are, kid," Daichi called out. "Don't hold back. Use everything. Ninjutsu, tools, whatever."
Nanami took a breath.
He brought his hands together in the cross seal.
"Multi-Shadow Clone Jutsu!"
POOF. POOF. POOF. POOF.
Four clones erupted into existence, flanking the original.
Daichi's eyebrows shot up. "Oho! The Forbidden Jutsu? And four of them? You've got reserves, kid! I see why Mom likes you!"
"Formation B," Nanami ordered.
The clones scattered. Two rushed Daichi from the left, two from the right. The original hung back.
Daichi laughed. He didn't move his feet. As the first two clones arrived, throwing synchronized punches, Daichi simply caught their fists.
"Too slow!"
He threw them. Literally threw them. The clones flew through the air and crashed into each other, dispelling in puffs of smoke.
The other two clones arrived. One slid low for a sweep, the other jumped for a high kick.
Daichi stomped the ground.
Earth Release: Mini Tremor.
The ground shook violently. The sweeping clone lost its balance and face-planted. Daichi backhanded the jumping clone out of the air without looking.
Poof. Poof.
All four clones gone in ten seconds.
"Is that it?" Daichi grinned. "Good distraction, but—"
He paused.
Where was the original?
He looked forward. Empty.
Above, his instincts screamed.
Daichi looked up.
Nanami was falling from the sky. He had used the smoke from the last clone as cover to jump, using the tree branch as a springboard.
But it wasn't just a jump.
Nanami's right hand was held back. And in his palm, something was screaming.
It was a ball of blue chakra. It was swirling, grinding, glowing with a chaotic, contained power. It sounded like a jet engine trying to start up inside a jar.
The Rasengan.
Mito stood up on the porch. Her teacup rattled on the saucer.
"That's..." Kaede whispered.
Tsunade's eyes were saucers. "No way..."
Daichi's eyes widened. He felt the pressure. That wasn't a Academy jutsu. That was concentrated, A-rank destruction.
Time seemed to freeze for Daichi Senju. As a Jonin, he had faced elemental jutsu, blade masters, and explosions. But this... this was different.
His instincts, honed on the battlefield, screamed a single word: DANGER.
This wasn't a child's prank. This was a meat grinder. The rotation speed of that sphere was enough to tear muscle from bone, to twist a limb until it was nothing but pulp. If he blocked this, he wouldn't just be bruised; he would lose an arm.
Move, his brain fired. Move or die.
Nanami thrust the sphere forward. "Take this!"
Daichi stopped smiling. He didn't block. He moved.
He shunshined—a flicker of pure speed.
Nanami's hand hit empty air.
Crash.
He slammed the Rasengan into the ground where Daichi had been standing.
The earth exploded.
Dirt, grass, and stone were pulverized. A crater the size of a small car appeared instantly, the ground spiraling outward in a perfect vortex of destruction. The shockwave blew Nanami's hair back and sent dust rolling across the entire garden.
Nanami landed in the crater, breathing hard. The sphere dissipated.
He looked up.
Daichi was standing three meters away, near the koi pond. He looked at the crater. He looked at Nanami. He looked at his own hand, which was trembling slightly—not from fear, but from the shock of needing to dodge a six-year-old.
Silence.
Absolute, ringing silence.
Tsunade ran to the edge of the porch, then leaped down into the garden. "KENTO! What was that?!"
Nanami stood up, dusting off his knees. "Just an incomplete version of a jutsu."
"Incomplete?" Daichi muttered, recalling Nanami's earlier statement. "Kid, if that's incomplete, I don't want to see the finished version."
He turned to Nanami and slapped a heavy hand on his shoulder.
"Shape transformation," Daichi said, his voice serious now. "High level. No hand signs. Just pure chakra control. Did you invent this?"
"I... deduced it," Nanami hedged. "Based on the rotation of a water balloon. It seemed like a logical progression of chakra density."
"Logical progression," Daichi repeated, looking at Mito.
Mito walked down the steps. She stopped at the edge of the crater. She looked at the destruction, then at Nanami.
"You said you were interested in Fuinjutsu," Mito said. "But you have the talent for Ninjutsu that rivals Tobirama."
"I prefer Fuinjutsu," Nanami insisted. "This..." He gestured to the crater. "This is just a hammer. I want to be an architect."
Mito stared at him. Then, she let out a short, rare laugh.
"A hammer," she mused. "Yes. I suppose it is."
She turned to Daichi. "Well? Did he pass your test?"
Daichi scratched the back of his head, grinning again, though his eyes held a new wariness. "Pass? Kaa-san, he almost blew my leg off. Yeah, he passed. He's terrifying."
He looked at Nanami.
"You're welcome anytime, Kento-kun. Just... maybe warn me next time you're going to use a portable typhoon."
"I will file a notice in advance," Nanami promised.
Nanami bowed to the stunned adults. "Thank you for the spar. And the lunch. I should be going now. I have a scroll to study."
He picked up his bag, which contained the priceless Uzumaki scroll.
"I will see you next Sunday, Mito-sama."
"I look forward to it," Mito said softly.
Nanami walked out of the compound, his back straight, his step measured.
As soon as the heavy wooden gates clicked shut behind him.
That was too close, he thought, his heart hammering against his ribs. I used the Rasengan. I showed my hand. Now they know.
But it worked. I have the scroll. I have the teacher. I have the backing of the Senju.
He took a deep breath, composed himself, and stood up.
Phase 1 complete, Nanami thought, adjusting his collar. Now, the real work begins.
