Mori Calliope

Following the success of their Japanese-speaking virtual YouTuber series, entertainment company Cover Corporation and its subsidiary Hololive Production decided to branch out into the English market. Mori Calliope, one of the company's first generation of English-language VTubers, was first revealed on September 8, 2020, in a short promotional video that also featured the other four members of the Hololive Myth project. Later that year, she made her music debut on streaming services with the rap track "Excuse My Rudeness, But Could You Please RIP?" Further singles like "Cursed Night" (2020), "Off with Their Heads" (2021), and "Ibasho" (2021), as well as the EPs DEAD BEATS (2020) and Your Mori (2021), all helped Mori Calliope become one of the most popular figures in the agency's competitive roster and rack up millions of followers on her social media accounts. UnAlive, her first studio album, appeared in March 2022, followed by a third extended play titled Shinigami Note in July of that year. Thanks to the popularity of the single "CapSule" featuring first-generation VTuber Hoshimachi Suisei, the EP broke into the Top 5 of the Billboard Japan Albums chart. Her 3rd major album, Disasterpiece, was released on February 6, 2026.
