Sia Siberia, aka Octokuro, was born on August 15, 1995, in Russia. She moved to Japan at a young age and developed a passion for anime, manga, and Japanese culture. Her interest in content creation began when she started posting videos on YouTube in 2012, initially focusing on anime and manga reviews.

Octokuro (whose real name remains private, adhering to the industry’s code of anonymity) hails from Siberia—specifically, the region around Novosibirsk, Russia’s third-largest city and the unofficial capital of Siberia. Unlike the glamorous studios of Los Angeles or Miami, her origin story is rooted in a landscape of brutal winters, concrete apartment blocks, and a DIY internet culture.

The digital landscape is home to a diverse array of creators, but few have navigated the intersection of cosplay, independent video production, and international branding as effectively as Sia Siberia (often associated with the handle Octokuro). Her career offers a masterclass in how to transition from a niche hobbyist to a professional video content creator with a global footprint.
