A-chan

Yuujin A (友人A, Friend A), better known as A-chan (えーちゃん), was a female Japanese head of content, equipment technician and Virtual YouTuber associated with hololive. Originally hololive's first support staff member in charge of the technical aspects of Tokino Sora's streams, she became a VTuber in her own right through appearances in hololive content, eventually receiving her own Live2D model. A-chan served as the host/narrator in most collaboration videos uploaded to hololive's YouTube Japanese channel. She retired in June 2024 to take care of a family member.
