Background / History
The Red Eye originated from a small bloodline family in the Land of Birds. Before the clan’s decline during the Warring States Period, its ability to counter the Byakugan earned it the name Byakugan Killer. 151
Kumogakure acquired the clan during the Fire Stealing Plan. The Red Eye clan was attacked in the Land of Birds by assailants disguised as Kumogakure ninja; after the skirmish, the actual Kumogakure force prevailed and brought the clan into the Land of Lightning. 17
By the time the clan entered Kumogakure, its population had dwindled to the brink of extinction. Chishin Yusuke was the first child of the clan to grow up in Kumogakure and become part of its serving ninja force. 131
