Six Paths Senjutsu

The Six Paths Senjutsu is a heightened form of senjutsu used by the Ten-Tails' jinchūriki, Hamura Ōtsutsuki and those who obtain Hagoromo Ōtsutsuki's power.

Overview
This special form of senjutsu is suggested to have a connection with the pattern that consists of a Rinnegan-like marking and nine magatama below it, which appears on the user's back when this power is active, resembling the pattern on the back of Hagoromo Ōtsutsuki's robe. The pattern that appeared on Obito Uchiha's back when he used this senjutsu differs slightly from other known users, as it instead consists of a Rinnegan-like magatama appearing above the nine other magatama. As a heightened form of senjutsu, the user receives the same benefits and enhancements bestowed by Sage Mode, along with an improved healing factor and the ability to fly. They also gain an absolute mastery and comprehension of chakra, being granted knowledge of, as well as the ability to utilise all five elemental nature transformations and in addition make perfect use of Yin–Yang Release, which enables the user to manifest several Truth-Seeking Balls at their disposal. Inside of these orbs, the user is able to merge any or all nature transformations together, as well as alter the orbs' shape; which when combined in varied ratios and pairings, result in different effects.

In the cases of Obito and Madara Uchiha, when both used the Six Paths Ten-Tails Coffin Seal to seal the Ten-Tails within themselves and become its jinchūriki on separate occasions, they acquired this heightened form of senjutsu as a result of the Ten-Tails' power. Hagoromo and Hamura Ōtsutsuki were also able to utilise this senjutsu, with the former giving power to his son Asura Ōtsutsuki and his descendant Naruto Uzumaki to allow them both to receive this senjutsu as well, with the latter recipient obtaining this power during the Fourth Shinobi World War after a near-death experience. Naruto can use this special form of senjutsu in conjunction with the Six Paths Sage Mode, a heightened state of Sage Mode, along with the Six Paths Sage Chakra to greatly augment his abilities by being able to harness larger amounts of natural energy, thus enhancing his proficiency with both Sage Mode and senjutsu.
