The Nine-Tails Chakra Mode (九尾チャクラモード, Kyūbi Chakura Mōdo)[20] is a form that Naruto gained after he separated and sealed the Nine-Tails from its chakra. He can access its chakra directly whenever he needs it without interacting with the beast at all. In doing so, he gains a chakra shroud that resembles the Sage of the Six Paths' silhouette. The colour of his eyes changes from blue to orange, instead of red. Also, while the demon fox shroud is red and releases chakra as burning, acidic bubbles, this form's shroud is yellow and releases chakra as flickers of flame, instead.[21][22]
With the Nine-Tails' power under his control, Naruto's strength is significantly increased to the point where he can push a fully formed Tailed Beast Ball through a multiple layered barrier.[23] His greatly increased speed surpasses A's, even while clad in his Lightning Release Armour at full power.[24] Killer B had trouble determining if Naruto's speed was from the Body Flicker Technique, as all he saw was a "yellow flash" when Naruto attacked Kisame Hoshigaki, who was hidden inside Samehada.[25] This form's chakra shroud gives Naruto great protection, but he noted that it would have been dangerous if A had gotten a clean hit on him.[26] It is also shown to be superior to Naruto's Sage Mode as when he entered this form, he easily managed to break out of a Shadow Imitation Technique while in the latter form, he couldn't. Naruto can also use the shroud's chakra arms to help him create new Rasengan variants, such as the Spiralling Strife Spheres, the Spiralling Absorption Sphere, the Mini-Rasenshuriken and the Planetary Rasengan for example. The chakra arms give Naruto greater range of attacks as well as greater dexterity and manoeuvrability with his fighting style without the use of shadow clones. He has yet to complete the technique related to the Tailed Beast Ball: the Tailed Beast Rasengan.[27]
Like his predecessor, Mito Uzumaki, Naruto also gains the Nine-Tails' ability to sense negative emotions, even while he was inside a chakra isolation chamber within the Falls of Truth, something that not even the best sensor-type ninja can do.[28][29] Due to having the Nine-Tails' Yang chakra in this form, Wood Release techniques will react to the chakra's life-giving properties and mature into full-grown trees within a matter of seconds, either by contact or close range.[2][30][31]
However, using the Nine-Tails Chakra Mode is a huge risk. Naruto has to temporarily "shelve" his own chakra in order to use the Nine-Tails' chakra, which allows the Nine-Tails to automatically drain his original chakra. If the Nine-Tails manages to take all of Naruto's chakra, he will die. In addition, the Eight-Tails advised him against the use of the Shadow Clone Technique, as the Nine-Tails would absorb every portion of Naruto's chakra even faster for each clone he makes. Because of this same reason, Naruto has to limit the amount of time he spends in this mode.[32] Despite these risks however, once he was on the battlefield, Naruto deployed several of his shadow clones while in this mode to the different divisions to confront the White Zetsu Army, which indicates that the risks associated with this form are not instantaneous.[33] He has shown to stay in this form for an entire night and most of the morning during the Fourth Shinobi World War, much longer than that of Sage Mode.
