Tailed Beast Chakra
K'un, the hexagram of Sigma Uchiha, has stated that in order to perfectly manifest the Tailed Beast Chakra, one must have a unique source of chakra of their own. Those who have fully mastered the chakra of their beast, can attain the power of the tailed beast. Naidō, the original spirit guide of Sigma noted that this power is only exclusive to those that have also achieved the control over Hagoromo's chakra.
