Ch. 821Inner World
Shamu brought Naruto into his inner world to introduce him to the Nine-Tails and help him begin making peace with the beast. After Naruto asked Shamu to become his teacher, Shamu accepted, recruited him, and sent him back with instructions to keep using his old form of address.

- Naruto asked Shamu to be his teacher, and Shamu agreed, gaining a single-use Six Paths Sage Mode and Uzumaki Clan Chakra as rewards.
- Shamu introduced himself to the Nine-Tails and told him to stop interfering with Naruto's Chakra extraction, but the Nine-Tails refused to indulge Naruto.
- Naruto approached the Nine-Tails and tried to befriend him by sharing his painful past, but the irritated beast withdrew behind the gate.
