Kinkaku JUS | Naruto Mugen
During the First Raikage‘s reign, he and Ginkaku were part of a team that was assigned to capture the Nine-Tailed Demon Fox, but the two were swallowed during the confrontation. However, they survived by eating the flesh of the beast, and thrashed inside the tailed beast’s stomach for two weeks, eventually forcing the Nine-Tails to regurgitate them. Upon their escape, they both came out looking like miniature versions of the beast, due to having acquired a portion of the fox’s chakra.
During a peace treaty ceremony between Konohagakure‘s Second Hokage and Kumo’s Second Raikage, the two brothers staged a coup d’état that left the Hokage on the brink of death. During the First Shinobi World War, the Kinkaku force cornered the Second Hokage and his Escort Unit — an altercation which ended in Kinkaku killing the Hokage. At some point, he met Kakuzu, and he was still alive after the appointment of the Third Raikage. For his crimes, he became one of the most notorious criminals in the history of Kumo.
