Irako Clan Ancestor

The Irako Clan Ancestor was the founder and creator of the Irako Clan. During his battle with the Nine-Tails, Kurama, he managed to bite off one of it's tails, consuming some of Kurama's blood in the process. He later gained great power and nearly defeated Kurama until the demon fox disappeared. His offspring from then on would contain some of the fox's own chakra, although it becomes more diluted as more generations are created. His body is now encased in stone

Appearance
The Irako Clan Ancestor was a youthful and strong young man with shaggy crimson hair. He was taller than most and muscular due to all of his battles. He had symbolic markings that swirled around his shoulders, chest, and around his eyes, said to have been the marks of a special seal. He was never seen wearing a shirt and wore something similar to a grass skirt with purple pants.

Personality
Not that much is known about his personality but it can be said that he was brave, since he was able to battle a Tailed Beast without fear.
