Hyōryū Clan

The Hyōryū Clan was a noble clan from Uzushiogakure, or the hidden eddy village. When the village was exterminated, they ultimately also met their demise, but Shien Hyōryū, the last one lives on in konohagakure, and hopes to slowly rebuild his clan.

Background
The Hyōryū clan were ninja from the now extinct uzushiogakure, originally just a break off of the more popular Uzumaki Clan. They were extremely powerful water release users and had two hidens, the Hozuki Clans own hiden, the Water Gun Technique, and the whirlpool technique, which gave Uzushiogakure its name over time. The clan fell when the village was destroyed, but the Parents of Shien Hyouryuu survived for quite some time, then gave birth to him and died by konoha ninja sometime after the fourth shinobi world war.
