Anastasia, nicknamed Anya, is a 15-year-old idol under 346 Production. She was born on September 19, making her a Virgo, with blood type O. Standing 165 cm tall and weighing 43 kg, she has blue eyes and gray hair cut to neck length. Hailing from Hokkaido, Japan, she is of half-Russian heritage and spent her first decade in Russia before moving to Japan, making her fluent in both Russian and Japanese. She characteristically mixes Russian phrases into her speech, such as "Как Вас зовут?" often followed by Japanese translations. Initially unfamiliar with idols, she joined the Cinderella Project out of curiosity. Her primary passion is astronomy, especially stargazing, and she dreams of discovering and naming an asteroid. This passion shapes her idol image, weaving celestial and winter motifs—stars, snow, and ice—into her stage costumes and performances. After moving to Japan, she experienced loneliness and homesickness for Russia. Living in the dormitory with fellow idols Ranko Kanzaki, Koume Shirasaka, and Syoko Hoshi provided vital support, helping ease her isolation and fostering close bonds. This environment also led her to sometimes adopt mannerisms like Ranko's distinctive speech, reflecting her adaptable nature. As an idol, she serves as Hokkaido's regional leader and specializes in "Cool" performances. She forms the unit LOVE LAIKA with Minami Nitta, and also participates in Snow Fairies, Tranquil Whisper, New Year's Celestial Maiden, Snow Princess, and ☆Space Stars☆. Her journey involves gradual adaptation to idol life, including training camps and summer festival performances, contributing to her personal growth and sense of belonging. Key personality traits include a calm, collected, and often introspective demeanor, along with noted naïveté and a polite, reserved nature. She is professionally serious yet warmly attentive to colleagues and supporters, and enjoys hosting gatherings at her residence. Her character design emphasizes elegance and a cool aesthetic, often featuring intricate star-themed details.
