Holotori

HoloTori is an unoffical, self-declared subunit in Hololive. The Subunit was formed by Takanashi Kiara, Oozora Subaru, Pavolia Reine, and Nanashi Mumei for their bird inspired designs. While unofficial under Hololive Production, they are often referred to as the group made up of members who represent birds, or have bird inspired designs.

Naming
The name HoloTori is a combination of the Hololive「ホロ」name, and the Japanese word for bird, "Tori"「鳥」.
