Overview

CIEL is a virtual singer under KAMITSUBAKI STUDIO, discovered through the studio’s internal audition program “Kamitsubaki-shi Ijuu Teijuu-ka.” Recognizable by her blue hair symbolizing the sky, her artistic identity centers on the narrative of a girl who always looked down finally taking her first step forward.

Beyond solo activities, CIEL formed the cross-dimensional virtual music unit KUUSOU with real-world artist Sooda in early 2026, themed around “purity and softness.” She also performed the theme song for the theatrical anime Eiga Daisuki Ponpo-san, making her one of the more prominent next-generation virtual singers in the Kamitsubaki ecosystem.

Role and Creative Position

CIEL’s character concept revolves around transformation — a girl who spent her life looking down, now lifting her eyes to the sky. The blue hair serves as both a visual signature and a metaphor for this psychological shift from isolation to openness. Her vocal style tends toward clarity and gentleness, occupying a different register from the more dramatic expressions of the V.W.P members.

Within KUUSOU, CIEL’s voice forms a distinctive complementary relationship with Sooda’s. The unit deliberately blurs the boundaries between virtual and real, visual and auditory — embodying Kamitsubaki’s ongoing exploration of “cross-dimensional” expression.
