Nonna

Nonna, also referred to as sometimes "Blizzard Nonna", is a student from Pravda Girls High School. She's the vice commander of her school's Sensha-Dō team, as well as its sniper and she mainly operates a Soviet T-34-85 tank, although she can operate an IS-2 as well. In the anime, she only missed one shot when she served as the gunner of IS-2.

Nonna is a tall, beautiful and elegant girl with straight upper-back length dark-brown hair that has a small strand in the middle, light blue eyes and large breasts.

Her composure is absolute that she is never seen to raise her voice or lose her temper; everything she does is with the same measured grace and calculated resolve.

Nonna is well known for her calm and gentle personality and for her loyalty to Katyusha; Nonna does everything Katyusha asks of her, usually without hesitation or protest, most notoriously giving her a piggyback ride to compensate for Katyusha's small height. Despite this, she is not above making fun of her on occasions; it is fairly clear that only Nonna could get away with such behavior without inviting Katyusha's wrath, as their relationship is very close, very similar to that of a mother and daughter, despite the fact that Katyusha is ultimately in charge. Aside from Katyusha, Nonna's only known friendship is with Klara, a transfer student from a Russian school to whom she generally speaks in her mother-language —often annoying Katyusha, who cannot speak Russian.
