Siska Leontyne is a fearless female Indonesian VTuber affiliated with Nijisanji. Known for her role as an elite security officer of a top-secret company, Siska is not one to hold back, often roasting her viewers who dare to disturb or make her uncomfortable. She has a playful personality, frequently cracking jokes and accidentally using adult words in her streams. Siska's YouTube channel was created in August 2020, and she released her first cover song, "Yoru ni Kakeru," in October of the same year. With a growing fan base called "Siskamling," a clever play on "Sistem Keamanan Lingkungan" (Community Security System), Siska has made a name for herself in the world of virtual influencers. However, her journey as a member of Nijisanji will soon come to an end, as she is set to graduate in June 2023.
