backup dancer (hakos baelz)

The distinctive backup dancers employed by hololive EN's Hakos Baelz in her 3D dance performances.

Originally entirely black silhouettes with mouse ears and tails similar to Bae's own, they were updated during her February 28, 2026 birthday concert to full-color mouse girls featuring black masks, long-sleeved cropped jacket over crop tops, and shorts. There are usually two of them.
