ujikintoki ginka
An original character by Rakurakutei Ramen. Formerly a youkai in the form of a silver coin (thus her hair color), she's now taken a human shape to serve as a maid for her master, Kamishiro Seren, in the Karindou shop. At roughly 180 years old, she's often paired subordinately with her "twin" older sister, Kinka.
Unlike her older sister, she is disciplined, responsible, does almost all the domestic chores... and can USUALLY keep her yuri tendencies under cover. (So that her prey doesn't see it coming when she's about to strike!)
