The Raiden Ei Shogun is the Electro Archon and rules over Inazuma. Inazuma is a connection of large islands that each have a large history. The Raiden Ei Shogun is actually two people in one body with a different consciousness. The body is the Raiden shogun (The past Electro Archon) and the controller of the body is Ei the actual archon. The body is usually on auto pilot and actually has rules to make sure that she stays alive forever and never ages. During the Kahnrian’ war, Ei left her people to go save the Raiden Shogun, but when she arrived, she witnessed the Shogun’s last breath.
