Mini bio
How it started.
Suisei debuted independently on March 22, 2018, with the ambition of becoming a virtual idol. In May 2019, Suisei joined hololive’s INoNaKa Music label. A first full album, Still Still Stellar, followed in September 2021.
A voice beyond the stream.
In January 2023, Suisei became the first VTuber to perform on THE FIRST TAKE, singing “Stellar Stellar” with acoustic accompaniment. That same month brought the second album Specter. In a Billboard Japan interview with Ayase, Suisei described using the album to express struggles that did not usually surface during streams.
Bigger stages.
The “BIBBIDIBA” video passed 100 million views, and Suisei brought the solo show SuperNova to Nippon Budokan on February 1, 2025. The concert fulfilled a goal shared back in the independent days. Alongside solo work, Suisei performs with producer TAKU INOUE in Midnight Grand Orchestra.
The next chapter.
On March 22, 2026, COVER announced Studio STELLAR, Suisei’s personal agency. Solo music and streaming moved into that framework, while group and collaborative activities continued through a hololive affiliation. Performing at Tokyo Dome remains a stated goal.
