オリガ

A member of the Eastern Expeditionary Army of the Great Empire of Ivan.
Her machine is a precision model with formidable armour, allowing no enemy to come close.
She favours the colour red so much that she even has her machine painted in it, making her an unmistakable sight on the battlefield.

Reckless and free-spirited, yet upholding the ideals of chivalry, she shows the greatest respect to her foes.
She is fascinated by Mizuho, and her favourite words are samurai and bushidō.

She has sworn absolute loyalty to her superior, Varvara, with whom she shares a deep bond of trust.

“I must at least know your name, pilot of the white machine.”
