Kin and Gin

Kin and Gin appeared in 2014 video game called Yo-Kai Watch 2. Kin (Japanese: キン Kin) and Gin (Japanese: ギン Gin) are a pair of twin Boss Yo-kai presumably of the Wicked tribe. They are secondary antagonists of the Yo-kai Watch 2 game, the first movie, and are recurring antagonists in the anime.

The Yo-kai Medallium bio for Kin reads; "The older of the twin sisters who have dedicated themselves to Dame Dedtime. She can turn back time and rewrite history using the power of the Time Stone given to her by her mistress."

The Yo-kai Medallium bio for Gin reads; "The younger of the twin sisters who have dedicated themselves to Dame Dedtime. Her powers are scarily strong, but she can only use them when her big sis is nearby."

Kin and Gin are a pair of identical twin Yo-kai. They are both old and wrinkled with grey skin and wear black haoris, dark grey obis, medals, black socks, and sandals. They each have messy, poofy hair and a diamond on their forehead, but the difference is their coloration. Kin wears a red skirt, has lighter skin, blue eyes, and her hair, diamond, medal, and trimming on her robe and her sandals are yellow. Gin's skirt is blue, her eyes are red-orange, and her hair, trim, diamond are white, her medal is silver, and her sandals are blue.

Out of most of the Yo-kai introduced in the anime and the entire series in general, they stand out for being generally evil-natured Yo-kai. This is evidenced by their extremely cunning and manipulative nature: after subjecting their targets to relive their past memories until reaching the point of an important decision, the pair offers a chance to change their minds and ultimately history, as if to ensure a seemingly better future; however, this is all a ruse in order to achieve a sinister objective.

Also, they hold human relationships and values like friendship and loyalty in very low regard, as evidenced by referring to Jibanyan's story with Amy as stupid as well as deriding Shogun Waitington as a fool and falsely lamenting that nothing changed that time.

Kin and Gin have the power to manipulate time by performing a ritual that activates a giant clock using a Time Stone. This allows them to rewind time to stop attacks and send people back in time to a point where they would make an important decision, which gives them a chance to change their mind and alter time, but to the benefit of themselves. They also have the power to revive and recreate Wicked tribe Yo-kai and shoot lightning.
