A-chan

Yuujin A (友人A, Friend A), more endearingly referred to as A-chan, is the head manager and equipment technician associated with Hololive since the very beginning.

Personality
Better thought as a private talent within Hololive, A-chan is the head manager of the group who occasionally cameos as herself 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. 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.

She originally got her start being Sora's technician during high school due to how oblivious the virtual idol was with machines and software setup. This eventually lead to her being hired as a core part of hololive, not as an idol but as the company's technician, and eventually manager. She is heavily dedicated to her role to the point she admitted to reading business books in her spare time. She's also extremely orthodox compared to the holoIdols, having nothing immediately fantastical or glamorous about her and works a salaryworker's 9-5 job then goes home to watch some dramas (preferably comedies) before bed. She 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, lack of a proper debut or even a streaming schedule, 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 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.

Trivia

 * She claims to be a part time DJ.
 * She is into sports, specifically Soccer.
 * Like Houshou Marine, Natsuiro Matsuri, Hoshimachi Suisei and many other hologirls, she is also an alleged shotacon.
 * She has a lymphatic-massage fetish (erotic massaging).
 * Unlike Sora, she is terrible with horror games.
 * Her nerves are oftenly at the foil of Marine's desire to be annoying. This sometimes causes minor, oftenly comical feuds between the two, such as A-chan bringing in a hyperactive HoloEN manager (presumably Jenma) to get Marine to annoy her in reverse by pressuring her to shout her infamous "I'm Horny".
 * It is rumored that when A-chan gets punched, she doesn't flinch or care she got punched due to her being very resilient.
 * She is capable of speaking English.
 * A-chan was originally spoken about or featured in a few videos but only illustrated as a roughly-drawn woman's face with glasses and a hair tie. In July 2018 she received a full design, and in November 2018 A-chan started her own Twitter account. On 7 September 2020 she got a new 3D model, the same date as Sora's third anniversary debut.
