Honkai Impact 3rd non-playable character.
The late mother of Bronya Zaychik and wife of Alexei Sydavich Zaitsev, Bronya's father.
During the 2nd Eruption of 2000, Alexandra's husband died during a Honkai invasion in the Red Army base, with Cocolia being the only survivor. Cocolia stumbled upon Alexandra and held her hostage to keep her still after she managed to retrieve Alexei's car keys and pistol, but at the intentions of escaping the Honkai with her, as per the wish to save his wife and unborn child. Along the way, she got separated from Cocolia and met Hare.
Appearance-wise, it is clear from looking at her where Bronya's Silverwing: N-EX figure came from.
