He leads the hidden village of the Tsuchigumo Clan, a mysterious group that mostly stays out of the spotlight. He first appeared in Naruto Shippuuden Episode 145, though he's remained pretty obscure compared to other village leaders in the series. Fans interested in the more underground ninja clans often point to him as an example of the show's deeper worldbuilding—there's a lot more to the ninja villages than just the major five.
