Torii Seal

After ripping the Nine-Tailed Demon Fox's chakra from its will, Naruto's seal changed into a more elaborate one, appearing on his Nine-Tailed Chakra Mode. Creating several Torii by just touching his stomach and twisting his old key, he was able to not only imprison the Nine-Tails, but also completely disintegrate the massive Tailed Beast Ball that it had created. The Nine-Tails remarked that the seal is similar to that of what the Sage of the Six Paths used before being locked away again. Naruto then isolated the Nine-Tail's former chakra in between three torii so he could access it freely. He could also enter the seal itself without unlocking it and control the torii freely.

Despite completely separating the chakra from the Nine-Tail's will, the Nine-Tails still is able to consume Naruto's chakra even behind the bars.
