Biography

Hoshimachi Suisei’s official debut date is March 22, 2018. The official Budokan concert retrospective describes her independent beginnings before joining hololive and notes that she had named the venue as a goal in an early self-introduction. Her history links individual production, agency collaboration and a developing music career.

Her public catalogue includes NEXT COLOR PLANET, Bluerose and BIBBIDIBA. In 2024 she completed a three-city tour including Saitama Super Arena. On February 1, 2025, SuperNova brought her to Nippon Budokan.

The concert accompanied SHINSEI MOKUROKU and turned a longstanding ambition into a documented stage event. Her virtual identity is a performance medium; it is not evidence of autonomous AI authorship.
