Overview
ARU (存流 / ある) was a virtual singer in the SINSEKAI STUDIO branch of KAMITSUBAKI STUDIO and one half of Albemuth with ASU. She began activity on June 20, 2021 and graduated on April 9, 2024.
Her whisper-like, breathy, restrained vocal colour and white gothic-elegant visual identity, designed by Mai Yoneyama, formed one side of Albemuth’s contrast with ASU’s brighter and more impulsive singing.

Unit Relationship and Record Boundaries
Albemuth was an independent unit with its own name, visual concept, live project, and member-side albums. eve should therefore be recorded in both ARU’s connected history and the unit’s catalogue, while ARU’s post-graduation status should not be merged with ASU’s continuing solo activity.
