Both Kinkaku and Ginkaku are based on two characters from the Chinese classic "Journey to the West". In this story; the siblings are two demon king brothers, known as the Great King Kinkaku (金角大王, Kinkaku-daiō) and the Great King Ginkaku (銀角大王, Ginkaku-daiō), who live in the Lotus Cave (蓮華洞, Rengedō) on Mt Heichō (平頂山, Heichōzan). They possess five treasured tools, called the Amber Purifying Pot (琥珀の浄瓶, Kohaku no Jōhei), the Seven Star Sword (七星剣, Shichiseiken), the Banana Palm Fan (芭蕉扇, Bashōsen) the Golden Canopy Rope (幌金縄, Kōkinjō), and the Crimson Gourd (紅葫蘆, Benihisago). Amongst these, the pot and the gourd are capable of sucking in their opponents and melting them, once they are trapped within. Ginkaku is also said to have a technique that allows him to move mountains.
The demon king brothers' mother and uncle also appeared in the novel. Their uncle, Hu A'qi was a fox that fought with a halberd and lived close to his nephews. Their mother was a nine-tailed fox in the disguise of an old woman who lived in the Dragon-suppressing Cave.
The fact the demon king brothers' mother was a nine-tailed fox, is an allusion to how Kinkaku and Ginkaku possess the Nine-Tailed Fox's chakra after being trapped in its stomach.
Due to the brothers' ability to assimilate the Nine-Tails' chakra by eating its meat, the Fourth Raikage suspected them to be distantly related to the Sage of the Six Paths.
