Naruto: I'm Nine-Tails and My Host is Kushina

As the dark red chakra poured into her body, Mikoto Uchiha's expression twisted slightly. The sensation was overwhelming at first, unfamiliar yet potent.

But as time passed, she gradually adapted, her taut features relaxing into something almost serene. A faint smile even played at the corners of her lips.

Inside Mikoto's body, the great fox spirit, Kurama, received a system notification.

[Ding! Do you want to begin integrating Uchiha Mikoto's abilities?]

"Begin."

[Integration: Fire Release - Great Fireball Jutsu… 1%, 10%, 27%... 100%]

[Integration: Fire Release - Phoenix Sage Fire Technique… 10%... 100%]

[Integration: Fire Release… 100%]

…

As the fusion process continued, a pleased smile spread across Kurama's face.

"Finally... the Mangekyō Sharingan."

[Integration: Mangekyō Sharingan - Divine Reversion… 1%... 100%]

[Integration: Mangekyō Sharingan - Void severance… 5%... 100%]

[Integration: Complete.]

…

[Congratulations, Host. Full integration has been achieved.]

"At last!" Kurama exhaled deeply.

Now, he had fully assimilated Mikoto Uchiha's abilities. As a tailed beast, his chakra was near-limitless, allowing him to unleash the full potential of the Mangekyō Sharingan without the usual drawbacks that plagued Uchiha wielders.

"I wonder how much time has passed."

When Kurama emerged from the trance-like state, night had fallen. The scenery had changed—this was no longer the forest where he had begun the process. Instead, he stood inside Uchiha Mikoto's private quarters, the candlelight casting flickering shadows along the walls.

"Lord Kurama, is the fusion complete?" Mikoto's voice, filled with curiosity, broke the silence.

"Yes. It's all done. I owe you my gratitude," Kurama responded earnestly.

Mikoto tilted her head slightly. "Then… does that mean I no longer possess the power of my Mangekyō Sharingan?"

Kurama chuckled. "What are you thinking? This was a fusion, not a theft. Think of it like the copying ability of your clan's Sharingan—only taken to another level."

"Oh!" Mikoto visibly relaxed. For a moment, she had feared that she had permanently lost her strength.

But a single thought activated her dojutsu, and her black eyes spun into their familiar ring-shaped Mangekyō Sharingan. The power was still there, undiminished.

A gentle smile tugged at her lips. She had placed absolute trust in Kurama—even if it had meant losing her abilities, she had been willing to go through with it. That realization warmed something deep within Kurama's being.

The room fell silent, an almost awkward atmosphere settling between them. Kurama was the first to break it.

"By the way, Mikoto, where's Kushina?"

Mikoto's eyes flickered. "Since we weren't sure how long the process would take, she returned home. There were also urgent matters in the clan that needed my attention, so I had to leave her behind."

"I see. I should take my leave then."

Kurama's figure flickered and vanished into the night.

Mikoto stared after him, biting her lip. She wasn't sure what she was feeling at that moment.

Softly, almost to herself, she murmured, "Kushina, Lord Kurama is a good person... I've already paved the way for you."

Late at night, the lights in Kushina Uzumaki's home still glowed brightly. She sat alone on the balcony, her gaze lost in the endless night sky. Absently, she twirled a lock of her vivid red hair around her finger and brought it to her nose, inhaling its familiar scent.

A deep, soothing voice interrupted her thoughts.

"Kushina, it's late. Why aren't you asleep?"

Startled, she turned to see Kurama standing at the threshold of her room. Her initial shock melted into a playful pout as she crossed her arms.

"Oh? So you still remember your way back here, Kurama? Hmph! My room doesn't even have Mikoto's lingering scent anymore."

Kurama sighed. "Jealousy doesn't suit you."

Kushina huffed. Of course, she wasn't truly upset. She was just happy that he had returned safely.

Standing up, she circled around him, eyes scanning him up and down.

"You seem fine. Doesn't look like she did anything to you."

"What are you even suggesting?" Kurama quickly changed the subject. "Kushina, I have a hunch that the Third Great Ninja War is approaching. We should be prepared. There will be opportunities within the chaos."

Kushina's expression turned serious. If Kurama said it, then it was undoubtedly true

Kurama narrowed his eyes. "Are you ready to deal with the consequences?"

"Of course, I'm afraid! But I still want to try," she declared confidently, crossing her arms.

Kurama chuckled, shaking his head. "You're unbelievable."

—

Days passed in relative peace, but tension simmered at the borders. The shinobi of Sunagakure and Kumogakure clashed repeatedly with Konoha's forces along the Land of Fire's borders.

War was coming.

The village had no choice but to prepare for the inevitable battle ahead.
