Ginkaku

is one of Kumogakure's infamous Gold and Silver Brothers alongside his brother Kinkaku.

Background
The Gold and Silver Brothers were the most reviled criminals in the history of Kumogakure. Once, they were assigned to capture the Nine-Tails, 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. When in its stomach, they survived by eating the flesh of the beast.They could have captured him if they wheren't swallowed. An old Kumo-nin stated that when the fox finally regurgitated the brothers, they both came out looking like miniature versions of the beast due to having acquired a portion of the fox's chakra. During the peace treaty ceremony between the Second Hokage and the Second Raikage, the two brothers staged a coup d'état that left the Hokage on the brink of death.

Personality
Ginkaku believes that a shinobi of Kumogakure must be prepared to sacrifice their comrades if it means to accomplish a goal, and he praised Darui for attacking without concerning a hostage situation. He also believes that words are potent weapons in battle, and that betrayal and deceit are great for battle strategies, a reason why he and his brother were considered to be disgraces in their home village.

Appearance
Ginkaku, like his brother, was a relatively burly shinobi, albeit smaller than his sibling. He seemingly possessed long, silver coloured 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-coloured rectangular marking on his nose. Unusually, he had the same characteristic whisker-like marks on his face as Naruto Uzumaki.

His typical attire was 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 carried a large gourd around his neck attached to a thick rope.

Abilities
Ginkaku and his brother are well known for their prowess 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 acquired the Nine-Tails' 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 five treasured tools gathered by Kumogakure.

Treasured Tools
The brothers wielded the five Treasured Tools of the Sage of the Six Paths, all of which cost a large amount of chakra, enough to kill normal humans before they can utilise 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 and body, sealing them away for good. The Bashōsen allows them to create any of the five basic elements.

Jinchūriki Transformations
Though not shown, Ginkaku like his brother also had a Nine-Tails chakra shroud. An elderly Kumogakure ninja mentions them both looking like that when Kurama spat them out after two weeks within its stomach. The Fourth Raikage mentioned that during their time inside the beast they ate the flesh from its stomach in order to survive, which allowed them to take on the form of Kurama.

Shinobi World War Arc
In preparation for the Fourth Shinobi World War, Ginkaku is reincarnated by Kabuto Yakushi to fight against the Allied Shinobi Forces. Emerging from the sea near the Land of Lightning's coast, alongside his brother and among the White Zetsu Army, the two engage the opposing First Division. Confronted by Darui, he remarks that it was pathetic that they of all people would be used in the Second Hokage's technique, considering they defeated him.

Irritated by Darui's insolent tone, he retrieves the Shichiseiken from Kinkaku and with the Benihisago underarm, begins to battle the former. Switching opponents, Ginkaku is able to sever and confine Samui and Atsui's word souls. After tossing the sword to his brother, Atsui is tricked into uttering his most said word, allowing Ginkaku to seal him away. He then takes Samui hostage and tries to make them surrender, but struck by a guided barrage, she manages to escape. Hailing them both as true Kumo-nin, Ginkaku seals Samui despite her silence, before cursing Darui in his confusion.

Praising Darui for discerning that the curse will activate even if he remains silent, Ginkaku reiterates that deceit and betrayal were ideal tactics for shinobi, but when called a disgrace, he becomes enraged at the delluded "pawn" of the Raikage. However, just as Ginkaku was about to seal him, Darui's most said word changes whilst being absorbed, allowing him to escape unbeknown to the brothers. Knocked into Kinkaku from behind, Ginkaku touches the Kōkinjō, before being cursed by Darui after he commandeers the other tools. Separated from one another, Ginkaku fearfully requests his brother's help, yet as was his most used word, he is instead sucked into the confines of the Benihisago.

By nightfall, Tobi arrived at the battlefield and took both the Benihisago and Kohaku no Jōhei, each containing one of the brothers inside, intending to use their Kurama chakra to help enact his Eye of the Moon Plan.
