KUUSOU is a new-concept virtual vocal unit formed by virtual singer CIEL and artist Sooda, both affiliated with KAMITSUBAKI STUDIO.
CIEL performed the theme song for the theatrical anime film Pompo: The Cinéphile and attracted 400 attendees at her first solo VRChat live.
Sooda began her career as the vocalist of the unit Amayadori, gaining attention for her songwriting and a TikTok following of over 160,000.
Embracing themes of purity and softness through a school-uniform-inspired aesthetic, both members take part in songwriting as they continue to create new forms of music.
