A-chan (Ei-chan), also known as Yuujin A (lit. "Friend A"), is a Hololive staff member and manager. She is a popular character in the Hololive fandom, despite not officially being a Virtual Youtuber herself.
Character design by Amagai Tarou, personal emoji is 👓 (eyeglasses).
She is a close friend of Tokino Sora, having already taken an assistant role on her channel by the time that hololive was created with Sora as a founding member, and she is credited as "editor" in many of Sora's music videos. She's unique in that she's the only Cover Corp staff member so far to receive both official 2D and 3D models and that she takes part in members on-screen quite often, she's also featured regularly in the official web series Holo no Graffiti.
