"That's still better than being a puppet," Naruto said.
Shinshiki looked up at him.
"You really think so?"
"Yes."
"Interesting." Shinshiki stood up. "Then let me see"
"your resolve."
His body began to glow again.
"Otsutsuki Shinshiki: Final Form."
His body grew to fifty meters tall.
His eight arms became sixteen.
"This is the last of my power."
"Take this."
Naruto took a deep breath.
"Bring it on."
Golden light illuminated the entire space.
"Kurama."
"I know," the Nine-Tails replied. "Give it everything we've got."
Their powers merged.
Forming an even stronger form.
"Six Paths: Nine-Tails Mode."
Naruto's body was enveloped in Golden Chakra.
Nine tails sprouted from his back.
They charged at each other at the same time.
Their fists collided.
The walls crumbled.
The ceiling collapsed.
Sasuke shielded the others.
"This kind of power..."
"It's already beyond the realm of shinobi."
The battle continued.
Naruto and Shinshiki moved faster and faster.
Their fists and feet clashed.
Their Chakra collided.
Every blow carried the power to destroy the world.
"Not bad," Shinshiki said. "You can keep up with my speed."
All sixteen of his arms attacked at once.
Naruto barely managed to block them.
"Kurama..."
"I know," the Nine-Tails said. "Hang on a little longer."
"I'm figuring something out."
"What?"
"You'll find out soon enough."
The Nine-Tails' Chakra began to change.
It turned from gold to red.
"My true power," the Nine-Tails said. "Tailed Beast Bomb: Maximum."
A massive black sphere gathered in Naruto's hands.
It was several times larger than before.
"Go!"
Naruto hurled the Tailed Beast Bomb.
But its power was too great.
It pushed him backward.
All sixteen arms strained at once.
At last, they stopped it.
"Phew..."
He gasped for breath.
"That was close..."
"It's not over yet."
Naruto appeared behind him.
"When did you...?"
