Naruto tried taking a step forward, his foot striking the water with a loud splash.
Curious and puzzled, he looked at the Nine-Tailed Fox before him.
The fox with nine tails radiated a terrifying aura, and its immense chakra left him deeply shaken.
"It's hard to imagine that he's actually sealed inside my body."
Murmuring to himself, Naruto reached out and rubbed the seal affixed to the prison gate.

The Nine-Tailed Fox shifted his enormous body with a rumble, then slammed his forepaws against the prison gate.

Just then, golden light flashed. A figure materialized, and a hand caught his wrist, trying to stop him.
"Sui."
"Don't do this."
