Names: Yukimora Rin (Female) and Yukimora Ayumo (Male).
Chakra nature: Both have Earth and wind nature.
Relatives: The Nohara and Are Distant relatives of the third kazekage.
Looks: Yukimora Rin bears a striking resemblance to Nohara Rin, Her Deceased cousin, but Yukimora Rin's Hair is lighter and slightly less straight As seen in the comparable photos, and Yukimora Rin has light grey eyes, not brown.

That is Nohara Rin.

These are pictures of Yukimora Rin.

Because of being related, no mater how distantly, to the third kazekage Both twins have the Magnet Release Kekkei Genkai. Rin, Who has the same type as Gaara, uses sand, but it cannot be controlled without Rin or Gaara nearby. Ayumo uses iron, and it protects him from anything natural like a human, metal or nature, but does not protect him against fire jutsu.

Rin is also blind. She also hosts the Ichibi along with Gaara, being sealed with it moments after birth because it was seen to be better to have two Jinchūriki than just one. Unlike Gaara, Rin was still feared in the village when Gaara became Kazekage. Rin did die when Shukaku was taken out of her, she was brought back later on in the series by Nagato, Who Naruto had asked to bring her back.
