Nonna

Nonna, also known as "Blizzard" Nonna, is one of the supporting characters of Girls und Panzer. 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. In the official spin-off manga Motto Love Love Sakusen Desu!, she's also shown to be very protective of Katyusha and literally acts like Katyusha's mother, confirming herself to be Katyusha's parent when others mistook her so, much to Katyusha's frustration (Darjeeling later imitated this behaviour towards Orange Pekoe). She's also the only one in the series who Katyusha actually fears when she thinks Nonna is angry, as Katyusha literally begged for forgiveness when she accidentally poked Nonna's eyes while having a piggyback ride, after finding out Nonna was keeping some sort of "Katyusha Diary" (though based on the series itself, it's most likely just a log of Katyusha's cute, baby-like moments). The reason why Nonna carries Katyusha piggyback is shown in the Saga of Pravda manga: when Katyusha (not yet a commander) failed to get her strategy proposal brought to the teammates, because the staff thought of her as a little girl, Nonna lifted Katyusha onto her shoulders, saying, "By this way, no one will think of you as little girl anymore."
