Kazuma

Kazuma, also known as Furido, was once part of the 12 Guard Ninjas of Fire who was part in the half of the group who attempted a coup d'etat against one of the "Kings of the Fire country". He is also the father of Sora. In Episode 63 he, as Furido, told Sora that Asuma killed him. As Furido he is mostly seen eating potatoes.

Background
Kazuma was once part of the 12 Guard Ninjas of Fire, and part of the attempted coup d'etat where he somehow managed to survive.

He later tried to pursuade the Feudal Lord into killing of the Hokage as he saw that The Fire Country only needed one "King". However he was instead betrayed by Asuma Sarutobi, who told him that the Feudal Lord did not agree with him. After a long fight between Asuma and Kazuma, he died after a finishing attack by Asuma. Chikiru was the only one who knew about this, which was kept as a secret. He fought Kazuma as well, but lost in fight.

Fire Temple Filler Arc
However during the filler it is revealed that he has somehow survived and has gathered three followers in his cause of ridding the Fire Country of one of its "Kings".

Abilities
Kazuma´s special weapon, a staff where the top can be split in three parts with chain in between the joints, can destroy rocks and trees in an blink of an eye. It seems strong enough to block Asumas wind enhanced chakra blades.

He can also revive the dead with some sort of Tensei, that is combined with the earth element.

Trivia

 * In the Fire Temple Filler Arc, he has white hair and has a scar on his face, most likely from his last fight with Asuma.
