"The Seishi Clan are a very small, nearly extinct clan of Konoha. They wield a powerful bloodline, the Hyoketsu Senkai, which allows them almost complete control over the elements of water, wind and, what they are most famed for, ice. Very few members were ever able to activate their bloodline to its full extent."@en . "Seishi Clan"@en . . "The Seishi Clan are a very small, nearly extinct clan of Konoha.

Very few members were ever able to activate their bloodline to its full extent. The whole clan, minus the current clan head Shiki Seishi, are deceased. She and her parents were the only remaining clan members, as most died during the Kyuubi attack, and once they died Shiki was the only one left. It was then that she became the unoffical clan head (clan head's must be at least 16 to take up their position) at the tender age of six."@en .
