Ikasoruke is the leader of the Jikokukenin. He defected from Jikokugakure when they lost in the war against Kagegakure 2. He holds a loathing respect for Hikaru "Shadow" Kurosaki. He mainly is secretive to his subordinates, like Pain is to the Akatsuki. He was originally Hikaru's Hollow Self, but he was released from Hikaru.
