Minato Namikaze's sudden appearance saved Yuhi Shinku from a death that had already been written.
But the tableau he left behind was... awkward.
"Fourth Hokage." Shinku's voice was quiet, tinged with color rising to her cheeks. "You can put me down now."
He was still holding her. In full view of every ninja on the battlefield, Minato had swept her into his arms and vaulted clear of the Nine-Tails' swipe, and when his feet finally found solid ground, he had simply... not let go. Shinku sat cradled against his chest, one arm looped around his neck out of pure survival instinct, looking like she very much wished the earth would open up beneath her.
Minato blinked. Then, as though only now registering the situation, he set her down quickly and cleared his throat.
"Go and rest," he said.
"Yes, Fourth Hokage." Shinku straightened, composed herself with practiced speed, and withdrew.
The exchange lasted perhaps five seconds. Minato's mind had already moved on before she finished speaking.
He had struck Obito's back with the Rasengan. More than that: he had embedded a Flying Thunder God seal into the masked man's body during the impact, a second marker he could reach at any time. And threaded into that same strike, invisible to every eye on the field, he had used the contact to sever Obito's summoning contract with the Nine-Tails entirely.
That was why Shinku had been able to act. The moment the Sharingan's hold over the beast broke, there was a gap, a single breath of disorientation, and she had driven her pupil technique into it.
Sarutobi Hiruzen had the senior ninja squads pressing the Nine-Tails back, buying inches one jutsu at a time. He crossed the field at a pace that belied his age and came directly to Minato's side.
"What happened out there?"
"There's a man claiming to be Uchiha Madara." Minato kept his voice low and flat. "He orchestrated all of this."
Hiruzen's expression shifted, but Minato didn't give him time to process it.
"Sandaime-sama. If we seal the Nine-Tails back into Kushina's body right now, can she survive it?"
Hiruzen was quiet for a moment. "I haven't attempted it before. Her constitution is extraordinary — it might hold. But Minato, the Nine-Tails' chakra is vast. Resealing it completely, quickly... that's not a realistic proposition."
"What about half?"
"Half?" Hiruzen stared at him. "You want to divide the Nine-Tails?"
The words were already forming on his tongue — the Nine-Tails belongs to the village, this is not your decision alone — but then he looked at Minato's eyes. There was pain there, carefully contained, the kind a man carries when he has already done his accounting and accepted what it costs.
Hiruzen thought of Biwako, lying in the hospital.
He was silent for a long moment.
"Go and try," he said finally, his voice rough. "I don't know if it will work. But go, Minato."
Minato looked at him. Something passed between them that didn't need words.
"It won't be too much to ask of you, Lord Sandaime," he said, and a small, genuine smile crossed his face.
He had been Hokage. He knew precisely what kind of concession lived inside that sentence. Hiruzen had just chosen a man over a village's strategic asset, and both of them understood it.
Hiruzen shook his head slowly and said nothing.
Across the field, the Nine-Tails opened its enormous jaws. Chakra poured inward, dense and swirling, a Tailed Beast Ball taking shape between its teeth.
"Sandaime-sama," Minato said. "Buy me a few minutes."
Then he brought his hands together and shouted into the sky.
"Bunta!!!"
The summoning erupted from the air itself. Gamabunta descended like a falling mountain, all warted skin and pipe smoke and sheer mass, and landed squarely on the Nine-Tails' back. The impact of the Myoboku Mountain Crushing Technique shook the ground for a hundred meters in every direction. The chakra compression that had been building for the Tailed Beast Ball lost its coherence instantly. The ball collapsed inward, a flash of light and dispersing energy, dangerous to nothing.
"Go," Hiruzen said. His eyes were hard. Decided.
"Yes!"
Minato was already gone.
He materialized inside their house in the same instant.
Kushina lay on the bed, her red hair spread around her, her face pale in the lamplight. Naruto was beside her, curled small and sleeping, his breathing even and untroubled.
Minato stood there for a moment. Just looking at his son.
"Minato?" Kushina's eyes opened. She tried to push herself upright, arms trembling with the effort. "You're back. What happened? What's going on out there?"
He crossed the room and gathered her against him. Then, after a breath, he reached down and picked up Naruto too, holding both of them.
He didn't let himself think too hard about what holding his son represented in this moment. If Kushina's seal failed, if the plan fell apart, Konoha could not lose the Nine-Tails entirely. The child sleeping in his arms was the last contingency. That was simply the reality. Minato looked at Naruto's face and filed the thought away somewhere small and cold.
"It's not over yet," he said. "But the Sandaime has agreed to a plan. I need to explain it to you."
A Flying Thunder God seal activated beneath their feet. The world folded.
The three of them arrived together on a stone altar in the heart of Konoha, and by the time Kushina's eyes had adjusted to the open air, Minato had told her everything.
She took it in. He watched her work through it, the Jinchūriki's lifelong understanding of what living with the Nine-Tails meant, all of it reordering itself around what he was proposing.
She could survive. She could watch Naruto grow up.
"I'll do it," she said. No hesitation. "But how do we divide the Nine-Tails? It's not like splitting a scroll."
"Leave that to me." His voice was calm. His eyes were certain.
Kushina searched his face and seemed to find what she needed there. "All right. When you bring it here, I'll use the last of my strength to activate the Adamantine sealing chains and hold it in place. After that, it's yours."
"I know. Don't worry."
She reached up and touched his arm.
"Minato." Her voice dropped to something just between them. "Don't force it."
He blinked. Then the smile came, soft and unhurried, the one that had always been only for her.
"I'm not forcing anything," he said.
For the person he loved, letting go of everything felt remarkably like peace.
He disappeared.
On the battlefield, Gamabunta's great blade came down in a whistling arc while a diamond-hard rod of chakra drove upward from below, cracking against the Nine-Tails' jaw. Two attacks. One window of staggered movement.
The Nine-Tails recovered faster than either of them wanted. Nine tails swept outward in a single motion, and Gamabunta went airborne, spinning, his enormous frame crashing into the earth with a concussive boom. One claw came down toward Hiruzen.
Minato appeared on Gamabunta's body. He used the elevation, pushed off, and launched himself skyward. At the apex of the jump, he landed on top of the Nine-Tails' head.
The beast's eyes found him immediately. Slitted. Ancient. Burning.
"Namikaze Minato!!!"
The Nine-Tails spoke in human language, and its voice was all fury.
Minato tilted his head slightly. "You know me?"
The Nine-Tails' internal rage was, in its own way, genuinely comprehensive. It had been sealed inside Uzumaki Mito because Hashirama Senju could not be defeated. Then, after Mito died, inside Uzumaki Kushina. And Minato had been coming in and out of that seal for years. The indignity of it had accumulated into something vast and personal.
The resentment was real. It was also completely beside the point.
Minato pressed his palm flat against the crown of the Nine-Tails' skull and activated the seal.
Flying Thunder God.
The Nine-Tails and the man standing on its head both vanished.
On the field, the absence registered immediately.
"Lord Sandaime?" One of the senior squad's veterans looked over, uncertainty written in the set of his shoulders. "Should we pursue?"
Hiruzen raised one hand.
"Trust the Fourth Hokage."
He said it simply. He meant it fully. Minato had not taken the Nine-Tails without a plan, and whatever that plan was, exposing it to the entire field would only undermine him afterward. Hiruzen's role now was to hold the line here, hold the village's confidence, and keep the secret of what was about to happen to Konoha's tailed beast.
He had already made his peace with that cost.
He stood straight, staff in hand, and waited.
The Nine-Tails crashed into existence on the altar platform and found itself immediately wrapped in burning chakra chains.
Kushina had been waiting. The moment the massive fox appeared, she was already moving.
"Vajra Seal!!!"
The chains erupted from behind her, launching outward with the crack of displaced air. They wrapped around the Nine-Tails' body in rapid overlapping coils, locking its limbs, pinning its tails, yanking it down. The Adamantine sealing chains was one of the few techniques in the world designed specifically to restrain a tailed beast, and against it, the Nine-Tails' raw strength was blunted.
"ROAR!!!" The fox thrashed, massive muscles straining against the chains. The altar stones cracked beneath it.
Kushina held on. The color drained from her face with visible speed. Her knees threatened to fold. She stayed upright through will alone, pouring the last reserves of her chakra into the seal. Every second she held it was a second she was spending herself dry.
When she had given everything she had left, she looked up at Minato.
Her eyes found his hands. She recognized the seal he was forming, the same one she had taught him years ago, knowing even then that she was teaching a student who would surpass her.
Understanding arrived like a blade.
"No." Her voice broke open. "Minato, no — you can't —"
He was already smiling.
"Why would you stop a husband from protecting his wife and children, Kushina?"
The words were gentle. He meant every syllable.
"Ninjutsu — Shiki Fūjin!!!"
The space behind Minato tore open. Not visibly, not in any way that the ninja around them could perceive. But Kushina could see it, and if Finn — elsewhere in Konoha that night, his spiritual perception sharpened by the Secret Art of Spiritualization — had been watching this altar, he too would have seen it: a presence, vast and cold, pushing through the gap between the living world and something beyond it.
The Shinigami took shape. It looked nothing like a man. It pressed one enormous hand into Minato's back, fingers closing around something that had no physical form, and pulled.
Kushina's face crumpled.
She knew this technique. She had taught it to him. She knew that once the Shinigami was summoned, no outcome changed what happened to the one who summoned it. Successful or not, the soul was already spent. Already claimed.
Minato Namikaze was already dead.
"AHHH!!!" The Nine-Tails roared and thrashed. It could not see the Shinigami. It did not understand what was happening. It only knew that something had locked onto it — something invisible, something that ignored its claws and its tails and its enormous blazing mass entirely — and that this something was pulling.
The tailed beasts are pure chakra. Their will, such as it is, lives in that chakra. And chakra can be seized.
The Nine-Tails fought. It had been sealed twice before and it had hated both times, and it would hate this too, and it would fight until there was nothing left to fight with.
Then the pain arrived.
It spread through the fox's entire body at once, a sensation of being split along a seam that should not exist. It was worse than any wound it had ever taken in battle. The Nine-Tails felt itself being divided — not injured, not restrained, but halved — and it could not stop it, and it could not understand it, and the strength it had carried for as long as memory reached simply... fell away.
Half of its power was gone.
The Nine-Tails could not comprehend what had just been done to it.
