Akumu Clan

The Akumu Clan is a clan that originates from Kumogakure, though it has many branch families located in Amegakure and Kusagakure. The Akumu Clan is hailed as the strongest clan in all of the Land of Lightning because of the Clan's Kekkei Genkai, the Dark Release. Though it is extremely rare for members to obtain the Kekkei Genkai, they are exceptionally powerful as it is.
