Kaguya's 2nd Son (I was right last theory!) has ALREADY been mentioned by the name...

This is quite interesting...

From a logical standpoint - the Uchiha represent the most raw expression of Yang. Born with natural talent, immense chakra, and seem to just "Uchiha SMASH" anything with bullshit ninjutsu abilities.

The Senju and Uzumaki clans represent more balanced approaches.

A theoretical extension of that logic would have a hypothetical 'fourth' branch as the raw expression of Yin.

Jashinism would follow Yin to the extreme. Hidan had no amazing powers, per se. He just couldn't be killed. Moreover - he could stand in one place and pass any damage on to the target of his ceremony.

It's so passive that it's aggressive.

Even the idea that Jashin would prefer to use the actions of agents over direct confrontation falls in line with the idea of extreme Yin alignment.

All interesting points!
