A-chan

Yuujin A (友人A, Friend A), better known as A-chan (えーちゃん), is a female Japanese head content director, equipment technician and Virtual YouTuber associated with hololive. A-chan also serves as the host/narrator in most collaboration videos uploaded to hololive's Japanese channel. She used to be in charge of the technical aspects of Tokino Sora's live streams.

Profile
Hello, I'm Friend A, a hololive staff member. The hololive agency's first-ever support staff member. Always has too much on her plate due to the quirky idols and the massive amount of work she deals with, but she takes it in stride as she's truly happy about the agency's and its idols' growth. Together with Harusaki Nodoka, a newbie employee, she aims to make hololive the top idol agency in the world... and to be free of overtime forever.

Personality
Better thought as a private talent within hololive, A-chan is the talent director of the group who occasionally appears in interviews and events.

A-Chan seems rather deadpan and patient, only putting her energy into what she needs to. But when testing the tech that makes hololive events as stable as they should be, she can show herself to be quite dorky and easy to self-amuse, evident when she tries playing with motion capture or casually cosplaying as the other idols, as well as extremely friendly and relaxed for a Japanese salary-worker. She also shows herself to be a "Hiso Oshi", or someone who cheers and supports everyone in a group to an individual level. But in spite of this, she always keeps her eye out specifically for Tokino Sora due to their long friendship dating long before hololive and has even written heartfelt letters in the name of their friendship on the idol's anniversary streams to congratulate her for progressing so far into her career.

A-chan started as Sora's technician during high school due to how oblivious the virtual idol was with machines and software setup after doing extensive research on how to help her achieve her dream, eventually landing her on Cover Corp's doorstep. This eventually led to her indirectly creating and being hired as a core part of hololive, not as an idol but as the company's technician, and eventually head content director. She is extremely dedicated to her role to the point she admitted reading business books in her spare time on topics such as speaking skills and negotiation. She's also extremely orthodox compared to the holoIdols, having nothing immediately fantastical or glamorous about her and works a salary worker's 9-5 job then goes home to watch some dramas (preferably comedies) before bed. She is satisfied enough with this lifestyle, preferring something quiet and simple. Though it is running joke that she is forced to abide by black company philosophies, such as overworking, underpayment, or even payment in anything but money.

Although she is not a conventional VTuber due to her behind the scenes talents, non-existent VTuber schedule or even the lack of a proper debut, many fans have been wanting her to have her own channel for a long time. Some joke that the hololive's main channel is her channel, but others take this statement seriously as it's the channel she manages and appears on the most. But in of spite this, she is perfectly content working in the shadows of the other idols and regularly promotes their activities, antics and collab schedules on Twitter and is observant of an idol's talents, personality and strengths enough to know when she should offer private feedback or stay out of the way to let them grow.

Appearance
She has short, dark blue hair with a light blue hair ribbon on the back of her head, and blue eyes with glasses.

Background
A-chan was first introduced on 21 September 2017 during one of Sora's streams on her channel, however A-chan didn't talk much, often just being mentioned while remaining off camera.

2018
On 5 April, Sora drew A-chan as a little head with glasses and a hand, hololive's "Sora Records" refer to this form as "A-bean". From this moment on this drawing was shown frequently every time Sora talked about A-chan, as she didn't have a model yet.

In July, she debuted her 3D model during an online event that Sora also attended. One characteristic of this early 3D design is that she had a hair clip in the form of an "A" on the right, and that this model was in lower quality compared to Sora's. She would get a second model afterwards.

She created her Twitter account in November.

2020
On 7 September, she got her third 3D model, the same date as Sora's third anniversary debut.

2021
On 10 May, A-chan became the host of "radio-style" news and music program called "Holo no Koshikake" (ホロのこしかけ), aired on the hololive official YouTube channel at the end of every month.

During its first broadcast, A-chan also debuted her second 2D costume, in this costume she wears a striped blouse with a dark blue jacket on top, alongside wearing a corporate ID held by a blue lanyard. The new outfit also features improved facial expressions and animation.

2022
On 9 May, A-chan, along with Harusaki Nodoka, received an official biography akin to other talents on the hololive website.

2023
On 18 March, during hololive 4th fes. A-chan debuted her second 3D costume having the same design as her second 2D costume.
