Futsui Clan

The Futsui Clan (風追一族, Futsui Ichizoku) was a cadet branch of the great Futsui Clan. Merely a year after its foundation, Futsui engaged and defeated its parent in a civil war. Usurping all the powers of Fuyuki, Futsui quickly became the most feared great noble clan in Land of Bush. Its extreme influence and power, however, led Futsui to its extinction as the paranoid King of Bush ordered them to be exterminated in 40 BN.

Fuyuki Clan
Main article: Futsui Clan The Futsui Clan (風追一族, Futsui Ichizoku) was a cadet branch founded by the twins Aki and Tsuki Fuyuki in 330 BN. Futsui became one of the few cadet in history to eclipse the parent in power, surpassing Fuyuki in just a few years after being founded, by utterly defeating the Fuyuki in a civil war. Fuyuki clan was spared in the aftermath but it lost most of its lands and titles to the Futsui, and never recovered from it.
