Gold and Silver Brothers

The, also known as the , are two infamous shinobi from Kumogakure. The brothers share similar appearances to one another, including whisker-like marks on their faces, much like those of Naruto Uzumaki. They were once assigned to capture the Nine-Tailed Demon Fox, but were instead swallowed whole by the beast. They survived inside the fox by eating the chakra-meat of its stomach for two weeks, which caused the Nine-Tails to regurgitate them.

During their lifetime, the siblings were known to have assaulted the Second Hokage and Second Raikage during a peace pact, in which they brought the Second Hokage to the verge of death. These actions have caused them to be considered disgraces to the village due to their belief of treason and deceit being battle strategies.

When the pair are eventually resurrected by Kabuto Yakushi; their attendance alone caused one Kumogakure shinobi who observed them to tremble in fear and almost provoked A, the Fourth Raikage, into completely disregarding his duties as leader of the Allied Shinobi Forces to personally confront the brothers, due his great concern over their presence on the battlefield. Eventually, the brothers clashed with Darui, the Commander of the First Division of the Allied Shinobi Forces. But before the battle between Darui and the Gold and Silver Brothers begins, Samui and Atsui interfered, both of whom fell prey to the Benihisago. Darui managed to seal Ginkaku into the Benihisago after stealing it, and then sealed Kinkaku into the Kohaku no Jōhei. A the current Raikage noted that they may be the offspring of the Rikudou Seninn
