Irina Leskova, a Russian exchange student in her third year at Satsukibashi High School, arrived in Japan after independently studying its culture through anime, manga, and ACG media. Her birthday falls on February 19. Physically, she has blonde hair, green eyes, stands 170 cm tall, weighs 56 kg, and has blood type A, with purple as her theme color. Alongside academics, she works part-time at Akihabara's Café Rabbit Hutch, a surviving otaku establishment. Her hobbies include collecting military paraphernalia, and she strictly adheres to rules, displaying intolerance for violations. Fluent in Japanese, her personality blends seriousness, strictness, and stubbornness, often masking genuine feelings with a tsundere demeanor. She joins Café Rabbit Hutch's efforts to combat memory-eating viruses threatening fictional worlds, applying otaku-acquired skills to restore corrupted narratives like virus-altered story elements. Her dedication to preserving these realms stems from her background as an outsider who embraced Japan through its pop culture.
