Like this 6 months passed as he started his chakra growth started as he and Kushina become more closer
As time pass the nine tail night begins as the black room got distroyed and Kushina and Minato are fighting the raged nine tail fox
A massive roar echoed through the village as the Nine-Tails, its crimson fur shimmering under the moonlight, was summoned through a sudden swirl of space. Its eyes, once wild and feral, now spun with the cursed power of the Sharingan, enslaved by an unseen force.
Inside a hidden safehouse, Kushina Uzumaki, pale and weakened, had just given birth to Naruto and Hina Uzumaki, her breathing shallow. Suddenly, the wall burst apart, and the monstrous beast loomed, its gaze locked onto the weakened jinchūriki.
The Sharingan in its eyes spiraled faster—controlling, commanding—and with a thunderous growl, the Nine-Tails lunged.
Just as its claw descended toward the unconscious mother and her newborns, a yellow flash lit the room.
Minato Namikaze, the Fourth Hokage, appeared in an instant, marked kunai in hand. With his [Flying Thunder God Technique], he swapped Kushina and the babies out of harm's way in the blink of an eye, placing them in a safer location.
But the Nine-Tails wasn't done.
It roared in fury, rampaging with uncontrolled power, as Minato gritted his teeth. Even for the Yellow Flash, the beast's sheer size and might were overwhelming.
"This is bad…" he muttered, sweat on his brow. "Handling it alone... won't be easy."
Still, he stood firm, cloak fluttering in the storm of chakra, ready to protect his family and his village at all costs.
The ground trembled as the Nine-Tails swung its massive tails, sending shockwaves through the surrounding area. Minato flickered from spot to spot with his [Flying Thunder God Technique], evading the destructive strikes while trying to formulate a counter.
"This level of control… someone's using the [Sharingan] to manipulate it," Minato thought, eyes narrowing. "It must be... Uchiha."
Suddenly, a figure cloaked in black with a spiraling mask appeared atop a distant cliff, watching with eerie calm.
"You're too late, Fourth Hokage."
The masked man's voice was cold.
"Tonight, Konoha will be destroyed… and the Nine-Tails will bring it down."
Minato's eyes widened, heart pounding. But he couldn't waste time. The village… his family… everything was at stake.
He disappeared again in a flash, reappearing inside a prepared sealing chamber. Kushina, barely conscious, clutched the twins in her arms.
"Minato… the children…"
He gave her a soft smile. "I'll protect them. No matter what."
Outside, the Nine-Tails roared once more and unleashed a Tailed Beast Bomb. Minato appeared atop a cliff, forming hand signs at blazing speed.
"[Summoning Jutsu: Gamabunta]!"
The giant toad appeared with a puff of smoke, blocking the blast and leaping toward the beast.
"Hold it down, Bunta!"
As Gamabunta clashed with the Nine-Tails, Minato formed another sequence of hand seals.
"[Dead Demon Consuming Seal]…"
His voice trembled. He knew what this jutsu meant.
He glanced at his newborns—Naruto and Hina—and then at Kushina, who had now stood up despite her condition.
"We'll split the Nine-Tails," he said. "I'll seal the Yang half into Naruto… and the Yin half…"
"I'll take it," Kushina said softly, her chakra chains forming behind her. "Let me help. Just one last time."
With her remaining strength, Kushina held the beast in place with [Adamantine Sealing Chains], long enough for Minato to complete the jutsu.
As the Shinigami loomed behind him, Minato's hands glowed with sealing power. He whispered an apology to his children.
The sealing began.
As the Shinigami loomed ominously behind Minato, he could feel the weight of the decision he was about to make. The price of sealing away the Nine-Tails would be steep—his life, his future with his family—but it was the only choice.
"Minato, no…" Kushina's voice was weak but firm. "You can't… If you die, who will protect Naruto and Hina?"
Minato's eyes softened, his hand gently brushing against her cheek.
"I'll always be with them, Kushina… In spirit, and through this seal."
He turned back to the Nine-Tails, his expression resolute. "I'm sorry, but this is the only way."
With the [Dead Demon Consuming Seal] complete, the Shinigami reached out its skeletal hand, its shadow cast over the room. The grotesque deity's jaws began to consume the Nine-Tails' chakra, pulling the beast's immense power into the dark void of the seal.
"It's done…" Minato whispered, watching in silence as the Yang half of the Nine-Tails was absorbed into his son, Naruto, while the Yin half was drawn toward Kushina, its presence lingering in her as she became the vessel.
But the strain was too much.
Minato could feel his life force slipping away, the Shinigami's curse tightening. Yet, even as death closed in, he smiled softly at Kushina.
"I'm sorry I won't be there to see them grow up."
His voice was barely a whisper, but his love was clear. "But they'll be strong… because of you."
Kushina, her face etched with both sorrow and strength, nodded. "I'll protect them… for as long as I can."
In that moment, the beast's last roar echoed through the village, before the darkness settled.
"Naruto… Hina… Stay strong."
And then, with a final, fleeting touch of chakra, Minato Namikaze and Kushina Uzumaki were gone—leaving behind a legacy of love, strength, and sacrifice that would guide their children.
