Career

Sistine Khun Doena debuted as a virtual streamer on June 9, 2023, at 19:00 Korean time. From the start, she presented herself as a fire saint who had been brought into an unfamiliar world. Her official X profile builds on this premise with an opening line in which she asks where she is.

She belongs to Time Less, a Korean VTuber team that runs its own official X account. The team's posts tag her alongside her fellow members Maririn and Saagi. In April 2025, Time Less announced its first live performance, Timeless Live, scheduled for June 21, 2025. The team asked other VTubers to send in congratulatory videos for the show, and Sistine Khun Doena reposted the call on her own account, describing the event as the group's first performance.

Before her birthday one year, she revealed an illustration that would be used for her first piece of official merchandise. Birthday merchandise has since become a recurring project. A later announcement listed a set of birthday goods for 2026, on sale from August 26 to September 26 of that year. At one point, her X display name included a note saying she was on a long-term streaming hiatus. Her account stayed active during this time, and she continued posting announcements and merchandise news.
