Tenko Clan
The First clan member was from the Kiyat clan long ago. His name was Abel Kiyat. Abel found out that he had a rare Kekki Genkei. He called it Shainingu Airon Boushi (Shining Metal Eye). He trained the eye and soon found out it's power. He had the power to manpl. all types of metal. He could even go as far as to manpl. the iron protein of the body. He could make his fingers turn into Pure Metal for great taijutsu use. When he went through the ranks of Shinobi his power grew. He soon coould make his whole arm metal, and he soon left the Kiat Clan. He Made his own clan the Tenko. The Tenko Clan has been lost in all Village History books for a long while. Hakushin is the last known carrier of this rare Kekkei Genkei. This clan is really good in all Elements of Jutsu, tai., nin., and gen.
