Jōtōmaru Mazuka

The Second Mazuka (ニダイメマズカ, Nidaime Mazuka) was said to be the legendary figure who created the Ten-Tailed Demon Fox and was the first one to control the legendary beast. He is also the first Mazuka to obtain and use the Chuto Taifugan, an upgrade of their Taifugan kekkai genkai.

Background
Not long after the founding of Konoha, Hashirama Senju began handing out Tailed Beasts to the stronger nations as a sign of peace. Realizing that the Land of Mountains would be absorbed if a beast wasn't obtained, the Second Mazuka began sealing powerful chakra whenever he encountered it. Later, after his Taifugan developed, he was able to use the Izanami ability, to shape the sealed chakra into the form of a large fox with ten distinct tails. He used his version of Izanami to quickly put down Yamagakure's enemies. During the fighting he awakened the Chuto Taifugan, and used it to give his Izanami physical form, which resulted in his death and the Ten-Tailed Fox's birth. It was later sealed with Ryun Mazuka by Yomi Mazuka.

Appearance
Although depicted only in Ryun's descriptions, several details can be inferred about the Second Mazuka's appearance. He had long, spiky white hair flowing backwards, in a style similar to the Rikudo Sage's. He wore what appeared to be a cloak with a high open collar or armor similar to that worn by Hashirama Senju, and battle armor, much like a samurai. He seemed to have horns on his forehead protector similar to the one worn by Jiraiya.

Trivia

 * He is one of only three people to have the Taifugan, and by extension, the Izanami technique. He is, however, currently the only one known to have activate the Chuto Taifugan.
