The Raikage (雷影, Literally meaning: Lightning Shadow) is the Kage of Kumogakure, a title bestowed on the village's leader. The Raikage is generally regarded as the strongest shinobi in the village. There have been five Raikage in the village's history.
The Raikage position was created after the formation of Kumo by A, the village's founder, that in anime was the second of the five Kage to emerge. How the Raikage is selected isn't clear; The Second was appointed for his long service and dedication as the bodyguard of the First Raikage and after the Third died, his son automatically became Fourth Raikage, a decision made many years earlier. Generally, the Raikage is known for its strong desire to protect the village and its inhabitants as well as for its pride. The Raikage works inside a central blue structure inside Kumogakure.
Throughout Kumo's history, the first four Raikage each had the given name A (エー, Ē, Viz: Ei, English TV: Ay). Each A had a tag-team partner named "B" (ビー, Bī), who was responsible for defending the Raikage and bringing out the Raikage's full power.
