He was born in the Keren clan, a clan of incredibly skilled puppeteers. He created his own two puppets, named Kaminoki (Divine Wood, as it was made from a tree that the Keren highly treasure because it was the tree that created the puppet of the first Keren, Hato Keren) and Saigo No Me (Last Eye, because it was made from his grandfather's last good eye. (his grandfather was dead and had lost both his eyes and replaced them with wooden ones only to lose another (It was also named Last Eye because it had one eye))), or Saigo. He created two Jutsu, called Emerald Lightning Death Blade (a green, more powerful version of the Chidori) and the Fatal Marking Jutsu. with this Jutsu, once he touches you with it, he leaves a seal on you permanently. This seal is like poison. every second you are sicker until you die. his puppets have the power to use both of these Jutsus.
