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, only putting her energy into what she need 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 is working a saleryworker's 9-5 job, going home to watch some dramas (preferably comedies) before sleeping. 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 and antics on twitter.
