Classify her and guess her origins

[The Blade]

Ancestry includes two ethnicities one of which is much more numerous than the other.
Edit: Many of you got the Russian part correct. Tobi was the first to conclude she is fully northeastern in origin. However, magyar_lany was the first who guessed her other ethnicity is Estonian. Her name is Katrin Siska.
Congratulations, people! You can now classify her.
