Hamura Ōtsutsuki (Ten Tails)

The First Mazuka (ショダイメマズカ, Shodaime Mazuka) was the founder of the way of life in the Land of Mountains, the founder of the Mazuka Clan and the first user of the Taifugan eye.

History
The First Mazuka lived around the time that the Sage of the Six Paths was preaching the ninja way. The First Mazuka was born in the west, outside of ninja territory, but came to the ninja Lands when he was in his mid-fifties. Though Rikudo Sage was seen as the savior and god by the new shinobi order for his sealing of the original Ten-Tailed Beast, the First Mazuka came from a land where another was promoted as the savior, and therefore disagreed with the the worship of the Sage. It was among these people, however, that he learned to mold chakra and eventually awaken his Taifugan. Armed with this power, he began to invent and create ninjutsu to promote and show off his idea of God, whom, unlike the Sage, he claimed not to be. He told of the west, where he originated, and their ideas of God and of His mercy. For this, the ninja exiled him to a land of savages, for his "atrocious" beliefs. In this new land, the people listened and out of his seed, the Mazuka clan came into existance. From that day forward, he was known as the "Outer Path" for refusing the Sage's "Inner Path". On his deathbed, he declared that one day, both path's would collide and in the end, only one would stand.

Inspiration

 * Most of the Naruto world's jutsu, and beliefs are Shinto based. The Sage of Six Paths is a reference to the Buddha, who came to teach the "Inner Path" and taught that all outside his teachings where part of the "Outer Path". The First Mazuka is someone, who's jutsu and teachings have Christian roots.
