Russia is a modestly-dressed woman with long beige-blonde hair (rather than Ivan's silver/gray). She has her male counterpart's unusual lilac colored eyes. Himaruya has described her personality as akin to a wearied mother figure who is emotionally unstable rather than childishly cruel. Her fanon human name is Anya Braginskaya. Anya is a Russian diminutive of Anna. She generally wears a long pink coat. Instead of a lead pipe, she is seen with a large shovel and matryoshka dolls. Kolko is a nickname for the female version of Russia, also sometimes referred to as Roshiko.
In their appearance in Volume 4, Italy referred to her as the origin of all suffering, and demanded that she be nicer to Estonia, which prompted her to say that she'd spread honey on and rolled him around outside a little bit.
