Pooshika and her sister Chaika are identical twins from Russia. Chaika is the twin in blue with glasses, while Pooshika wears red. The two girls fight with Project Blue in order to earn money for their ill father's medicine. Pooshika is bolder and more daring than the cautious Chaika, who tries to keep her in line. Pooshika sees Volk as her rival, but Volk doesn't care in the least. Pooshika's name in Russia (пушка) means "cannon."
