A (Second Raikage)
エー
A (エー, Ē; Viz “Ei”, English TV “Ay”) was the Second Raikage (二代目雷影, Nidaime Raikage; Literally meaning “Second Lightning Shadow”) of Kumogakure.
During his tenure, he entered Kumogakure into a formal alliance with Konohagakure. During the ceremony, both he, and the Second Hokage were ambushed by the Gold and Silver Brothers, who were attempting to stage a coup d’état. It is unknown what happened to him, but the Hokage was said to have barely escaped with his life.
