[Theory]The Uzumaki's, And Rikudou Sennin Were Inspired By The Onmyodo/onmyoji

[L.Lawliet]

I believe Kishimoto took the Onmyōdō as inspiration in writing the Uzumaki Clan and theOnmyōji Abe no Seimei as inspirations for Naruto, The Uzumakis and Rikudou Sennin, they may not be exact copies of each other but they have many similarities:

The Onmyōdō literally translates as "The Way of Yin and Yang" is an occult system that is an amalgamation of Shintoism, Buddhism and Taoism.

Rikudou Sennin had such mastery over the Yin–Yang Release that he used Yin to make his dreams take form, and then used Yang to make his fantasies real. He could even make them come to life.

The Onmyōji were the practitioners of Onmyōdō, The Onmyōji were specialists in magic and divination. Their court responsibilities ranged from tasks such as keeping track of the calendar, to mystical duties such as divination and protection of the capital from evil spirits. They could divine auspicious or harmful influences in the earth, and were instrumental in the moving of capitals.

The main powers of the Onmyōji are the exorcism and warding off of evil spirits, andcommanding the Shikigami (Kami-like spirits)

Just like the Uzumaki technique which summons the Shinigami: Shiki Fuujin

Like the Shiki Fuujin, the Shikigami is summoned through a complex mystical ritual, and like the Shiki Fuujin, the Onmyōji's life and spiritual force is connected to the "Shiki" if the summoner is careless, his shikigami may get out of control in time, gaining its own will and consciousness. In this case the shikigami will raid its own master and kill him in revenge.

The Shiki Fuujin in Naruto however kills the caster automatically:

The powers of the Onmyōjis over demons and spirits are very similar to the Uzumaki's Fuuinjutsus

Rikudou Sennin who is probably an Uzumaki himself vanished the most powerful demon in Narutoverse: The Juubi

The Onmyōjis were said to possess extremely long lives and good health like the most famous Onmyōji Abe no Seimei

Like the Uzumakis who were said to possess extremely long lives and vitality/chakra

The most famous Onmyōji Abe no Seimei, is the son of the fox spirit (kitsune) Kuzunoha

Naruto on the other hand is the son of Kushina, who has the nine-tailed fox sealed inside him, Kurama
