Ginkaku

was one of Kumogakure's Gold and Silver Brothers.

Background
The Gold and Silver Brothers were the most reviled criminals in the history of Kumogakure. Once, they were assigned to capture the Nine-Tailed Demon Fox, but were swallowed whole. However, they survived, and thrashed inside the tailed beast's stomach for two weeks, eventually forcing the fox to regurgitate them. A portion of the fox's chakra remained within them, giving them a large chakra reservoir, and allowing them to use the four of the five ultimate treasures of the Sage of the Six Paths without dying from the large chakra consumption. During the peace ceremony between the Second Hokage and the Second Raikage, the two brothers staged a coup d'etat that left the Hokage on the brink of death.

Appearance
Ginkaku, like his brother, is relatively burly, albeit smaller than his sibling. He seemingly possesses long and light-colored hair with prominent dark tips, arranged in a style reminiscent of a Native American headdress. These features are accentuated by the presence of two distinctive horns on his head as well as a light colored rectangular marking on his nose. Unusually, he bears the same characteristic whisker-like marks on his face as Naruto Uzumaki, due to the fact that he was trapped in the Nine-Tailed Demon Fox's stomach for two weeks along with his brother. His typical attire is comprised from the standard Kumogakure flak jacket, worn over a high collared sleeveless uniform, and a pair of simple wrist-guards. The kanji for is tattooed on his right shoulder. He carries a large gourd around his neck attached to a thick rope.

Abilities
He and his brother were well known for their strength during their lifetime, so much so that one Kumogakure shinobi trembled in fear when he saw them and the Fourth Raikage considered disregarding his duties as leader of the Allied Shinobi Forces to personally confront the pair. The brothers both possess enormous chakra reserves, likely due to having been infected with the Fox's chakra (which they received after being trapped inside its belly for two weeks). Furthermore, he and Kinkaku were the only ones who were able to use the four of the five ultimate ninja treasures gathered by the Kumogakure.

Five Ultimate Treasures
The brothers wield four of the five ultimate treasures that the Sage of the Six Paths once wielded, Bashōsen, Benihisago, Kōkinjō and Shichiseiken, all of which cost a large amount of chakra, enough to kill normal humans before they can utilize the tools properly. The brothers can use them due to the combination of their high chakra level and the fox's chakra. By combining the Benihisago, Kōkinjō and Shichiseiken, they can capture their opponent's soul and body, sealing them away for good. The Bashōsen allows them to create any of the five basic elements.

Shinobi World War Arc
After his resurrection by Kabuto Yakushi, Ginkaku and Kinkaku are part of an Akatsuki coalition sent to the western coast of the Land of Lightning, where they are met by the First Division. As the brothers are confronted by Darui, he remarks about how pathetic it is that they of all people would be used for the technique created by the Second Hokage, considering that they left him on the verge of death. He and his brother then take out four of the Treasured Tools of the Sage of the Six Paths, and begin to do battle with Darui, Samui, and Atsui. Ginkaku manages to sever Samui and Atsui's souls with the Shichiseiken and takes them hostage with the Benihisago. He tosses the sword to his brother, who tricks Atsui into saying the word he says the most allowing Ginkaku to seal him away. Ginkaku then manages to take Samui in order to make Darui surrender. Darui manages to free Samui, but Ginkaku seals her away soon after, despite her not saying anything.

Trivia

 * literally means "Silver Horn".
 * Both Ginkaku and his brother are likely based on two characters from the Chinese classic "Journey to the West". In this story, Kinkaku and Ginkaku are two demon king brothers, known as the and the . The siblings possess five treasured tools; one of which, called the, had the ability to suck in their opponents, before melting them once they were trapped within. This item presumably served as the inspiration behind the distinctive gourd that Ginkaku is observed with in "Naruto".
