Naruto: A Spy Who Got a System

The morning after the wedding, Hanekawa and Tsunade returned to the Land of Fire capital rather than remain in Konoha. For them, marriage changed nothing—they'd lived together for years. The ceremony was merely a formality, a public declaration to the ninja world that they were now husband and wife.

In the Hokage's office, Hanekawa reviewed documents with methodical efficiency. The ninja world remained stable. Problems arose and were corrected swiftly. Peace reigned, unified under his presence—no one dared disturb the balance.

"Kaguya," he called out.

A fragrant breeze preceded her arrival. Kaguya Ōtsutsuki materialized before him, no longer wearing ANBU garb. Like Samui, she'd abandoned the pretense. Once their relationships were acknowledged, there was no need for secrecy.

"It's time to prepare for Ōtsutsuki Momoshiki and his group," Hanekawa said, rising from his chair. "We're going to the moon today."

Though years remained before their arrival, preparation was essential. Early arrival would be catastrophic without countermeasures.

"Understood," Kaguya replied.

They both possessed Ōtsutsuki Urashiki's memories, courtesy of their victory. They knew the moon awaited them. Against three opponents when they numbered two, caution was paramount—though foreknowledge granted them advantage.

"There's another Ōtsutsuki descendant on the moon," Hanekawa mused, thinking of Ōtsutsuki Toneri. In the original timeline, he'd been a villain—blinding Hinata Hyuga, kidnapping her, threatening the world with meteorites. Yet he'd been redeemed by Naruto's words, later frozen by Urashiki to aid Boruto.

"Should we invite Tsukihime?" Kaguya asked, taking his hand.

"Unnecessary. A thousand years separates their timelines. She wouldn't know her descendant."

Kaguya said nothing, content to follow his lead.

Yomotsu Hirasaka.

The black portal consumed them both.

---

The desolate moon greeted them—endless wasteland broken only by a distant palace. A figure descended through the void, landing before them.

Ōtsutsuki Toneri, eyeless, bowed respectfully. "What should I call you both?"

"You know us?" Hanekawa raised an eyebrow.

"No. But I observed your battle with Ōtsutsuki Urashiki through the Great Tenseigan."

Hanekawa smiled, understanding. Without the Rinnegan—his own eyes—Toneri's strength was severely diminished. The Great Tenseigan remained, but borrowed power was never as reliable as one's own.

"Do you know Tsukihime?" Hanekawa asked.

"I've heard her name. She was our ancestor's mother."

"Tsukihime is my daughter with her," Hanekawa gestured to Kaguya.

Recognition dawned on Toneri's face. "That explains your power."

"Real Ōtsutsuki will arrive soon," Hanekawa explained. "Their goal is destroying the ninja world. We must stop them. When they come, use the Great Tenseigan to lure them here. We'll set a trap."

Toneri hesitated only briefly before agreeing.

They proceeded to the palace. The Great Tenseigan dominated the chamber—a golden orb, two meters tall, radiating immense power.

"This palace hasn't changed in a thousand years," Hanekawa observed.

"You were here a thousand years ago?" Toneri asked.

"I built it. The space passage between moon and world—that was my work too."

Toneri's shock was evident.

Hanekawa studied the Great Tenseigan. "Can you leave a dōjutsu within it?"

"Yes," Kaguya confirmed, placing her hand against the sphere.

The Rinnegan activated. Toneri felt the shift—the oppressive bloodline pressure transformed into lethal potential. She could kill him instantly.

"If caught off-guard, they'll suffer severe injury," Kaguya withdrew her hand.

"That's sufficient," Hanekawa said. Traps rarely guaranteed success, but advantage was advantage.

"Stay here and wait," he instructed Toneri. "In a few years, visit Tsukihime. She can take you to the Pure Land to meet your people."

Toneri's excitement was palpable. Alone for so long, the prospect of reunion overwhelmed him.

"I reward merit and punish failure," Hanekawa said calmly.

Yomotsu Hirasaka.

They vanished.

Twelve Years Later

Morning light filtered through silk curtains. Hanekawa stirred as Mei Terumi's silk-wrapped feet pressed against his thigh, her smile playful.

"Awake?" she asked, licking her lips.

He pulled her close without answering. Her smile froze momentarily before she recovered, blushing.

"Why so sudden?" she protested weakly.

"Isn't this why you woke me?" he countered, stroking her back.

Her suppressed sounds roused Samui, who yawned and glanced outside. The sun hadn't fully risen. She'd grown accustomed to their morning rituals—she and Mei Terumi had played supporting roles last night. Kaguya Ōtsutsuki and Tsunade bore the primary burden, with Kurenai Yuhi and Nohara Rin assisting.

Samui recognized Mei Terumi's limit approaching. She sat up and embraced Hanekawa from behind.

Mei Terumi tumbled away.

Hanekawa turned, touching Samui's head knowingly. She opened her lips slightly. He exhaled, then raised an eyebrow at Nohara Rin, who pretended sleep.

He reached for her thigh.

"Hanekawa..." Rin woke, unable to maintain the pretense.

"Come help Samui," he instructed.

Rin blushed but nodded.

"You're spoiling him," Tsunade's voice cut through. "Such requests should be refused."

Hanekawa turned. "Did you sleep well, Teacher?"

"What do you think?" she snapped. "You're busy constantly. I managed some rest. You didn't."

"I miss your embrace, Teacher."

"Don't even think about it," Tsunade sat up. "The children will wake soon. I'll prepare breakfast."

"Let Kurenai handle it," Hanekawa suggested.

Kurenai, already awake, rose without hesitation. Beyond Hanekawa, her cooking was the children's favorite. Tsunade's efforts were... adequate.

Tsunade's expression darkened. Before she could respond, Kurenai left.

Realizing she'd been outmaneuvered, Tsunade approached Hanekawa with clear intent. Without words, she pressed his head into her chest, then struck him repeatedly—not hard enough to injure, merely to punish.

Hanekawa endured until she relented, then reversed their positions for his own "lecture."

---

By ten o'clock, Hanekawa entered the living room. Six children played cheerfully, having finished breakfast.

"Father!" they chorused upon noticing him.

"Good morning," he greeted, smiling.

The eldest—his daughter with Tsunade—was twelve. The youngest, Samui's daughter, was nine. All bore his features distinctly.

"Aren't they attending school today?" he asked Kurenai, who sat on the sofa.

"Graduation day for your three students," she reminded gently. "You'll miss the ceremony if you don't leave now."

Hanekawa had forgotten entirely. Mei Terumi's morning antics were to blame.

He vanished instantly.

---

The Ninja Sect's graduation ceremony was underway. Hanekawa arrived discreetly, observing the notice board.

First place: Uzumaki Naruto.

He raised an eyebrow. This surprised him. With both parents alive, Naruto had developed differently than the original timeline. Yet ranking first in a comprehensive examination—combining academics and martial prowess—was impressive.

Second: Uchiha Sasuke.

Third: Hyuga Hinata.

Hanekawa reviewed their assignments during his years of occasional instruction. Naruto had learned Sage Mode, Flying Thunder God Technique, and Eight Gates. Sasuke possessed Mangekyō Sharingan and Wood Style—an unusual but powerful combination. Hinata had opened the Rinnegan itself, mastering its applications.

After waiting, he revealed himself to his three students.

Hinata approached first, smiling. At eighteen, her figure was breathtaking—second only to Tsunade and Samui.

"Teacher," she greeted, blushing as he pinched her cheek.

"How does graduation feel?" he asked.

"Good," she replied softly, her heart trembling. She lowered her gaze quickly.

Hanekawa suspected she harbored romantic feelings. He decided to let matters develop naturally. If it came to that, he wouldn't refuse. He'd favored Hinata in his previous life, after all.

Naruto arrived explosively. "Teacher! I'm first!"

Sasuke followed, expressionless but clearly displeased with second place.

Hanekawa distributed three scrolls containing their assignments.

Hinata's smile widened upon reading hers—she'd become the Hokage's secretary trainee under Samui's mentorship.

Sasuke led the Curse Seal Ninja Unit.

Naruto commanded the Summoning Beast Ninja Unit, inheriting Jiraiya's role.

"Report in two days," Hanekawa instructed.

As they departed, his expression shifted. His senses detected them—Ōtsutsuki Momoshiki, Ōtsutsuki Kinshiki, and Ōtsutsuki Urashiki.

They'd arrived far earlier than anticipated.

Kaguya materialized beside him. "They've reached the moon."

"We hide our tracks and go to the moon," Hanekawa decided, taking her hand.

---

The desolate moon. Three Ōtsutsuki examined the Great Tenseigan within the palace.

"This is the planet formed by the Earth-Shattering Star," Momoshiki observed calmly.

"Come out!" Urashiki's blue Rinnegan activated, gravity warping space.

Ōtsutsuki Toneri was dragged forward.

"A defective bloodline," Urashiki sneered.

"Kaguya's shame," Momoshiki agreed coldly.

"Where is Kaguya Ōtsutsuki?" Urashiki demanded. "Tell us, or become a pill."

"I guard the Great Tenseigan she left," Toneri replied carefully. "Her location remains unknown to me."

The three entered the palace, approaching the massive eye.

"Excellent," Momoshiki said. "This will serve our purposes perfectly."

As Momoshiki reached for it, nine truth-seeking jades materialized. They merged into a golden sphere, then transformed into a brilliant sword.

Golden Wheel Reincarnation Explosion.

The blade pierced Momoshiki's body. Blood erupted.

He screamed, absorbing the attack with his left Rinnegan. The lightsaber dimmed but had already inflicted grievous wounds.

Hanekawa appeared, his own Rinnegan blazing on his forehead.

"The Rinnegan?!" Urashiki exclaimed.

"Be careful!" Kinshiki warned.

Hanekawa unleashed six bones in three groups, attacking simultaneously.

Momoshiki countered with Shinra Tensei—a repulsive force that shattered the bones.

Hanekawa appeared above him, descending with both fists.

Eighty Gods Vacuum Attack.

Infinite power transformed into a tsunami. Momoshiki sneered and froze time.

But Hanekawa's entry I Am a Myth activated, resuming time and extending it to Momoshiki himself.

The golden lightsaber pierced his heart again.

Momoshiki screamed, using Shinra Tensei to force Hanekawa back. A summoned beast—dragon-headed serpent—emerged.

Hanekawa activated True Several Thousand Hands technique, manifesting a Thousand Handed Buddha statue that obliterated the creature.

Momoshiki summoned a firebird. It met the same fate.

The statue's fist descended. Momoshiki raised a crimson spiral—a Rasengan-like technique that shattered the fist.

Yomotsu Hirasaka.

Hanekawa reappeared behind him, golden lightsaber ready.

"I won't be hit three times!" Momoshiki opened his red Rinnegan, unleashing a shockwave that reversed the attack.

Turn Back Time.

Hanekawa's item Time Master activated. The shockwave reversed, and the lightsaber pierced through Momoshiki's body once more.

The thousand-armed statue's remaining fists fell upon him.

When the transformation ended, Momoshiki lay unconscious but alive—the Ōtsutsuki clan's immortality preserved him.

Hanekawa carried him to Myōboku Mountain, depositing him before the sacred tree. Branches ensnared him.

[S-Rank Talent Entry: Picking Momoshiki]

[Trigger Condition: Defeat Ōtsutsuki Momoshiki]

[Effect: Obtain Ōtsutsuki Momoshiki's pupil techniques]

Hanekawa nodded. Time freeze and crimson spiral were valuable additions.

Kaguya emerged from a black portal, dragging the unconscious Kinshiki.

The sacred tree's branches wrapped around him as well.

Two flower buds appeared atop the tree—two sacred fruits developing.

"Give me both," Hanekawa said.

Kaguya tilted her head, confused. She'd expected to share.

"Trust me," he said seriously. "I'll create another for you afterward."

After consuming both fruits, he could synthesize the Ōtsutsuki God entry through his system, transcending dimensions and reality itself. Creating new fruits would be trivial.

Kaguya raised ten fingers.

Hanekawa laughed. "Ten days."

"Ten years," she corrected.

"Ten years?" His eyes widened.

"I'll never tire of being with you," she stated simply, her expressionless face somehow conveying absolute sincerity.

Hanekawa approached, kissing her cheek. "Whether ten years or ten thousand, we'll be together."

[The End]
