Yuujin A (lit. "Friend A"), better known as A-chan (Ei-chan), is a Hololive staff member and director.
Despite not officially being a virtual Youtuber herself, she is a popular character in the Hololive fandom, which has reached the point that she has gained her own VTuber model (designed by Amagai Tarou). She uses it to host various collab and announcement streams on the main hololive Youtube channel.
Her name refers to her status as a personal friend of Tokino Sora, though she is not (and has never been) a manager of her or any other hololive member.
