To contrast that with nijisanji, since I know this thread is officially sponsored by hololive, their approach from start was "livers on the internet", thus not just any rando but a streamer with a specific quirk or talent (or lack thereof), which they pushed forwards and later expanded, before contracting back again some 8 or so months ago. This changed somewhat when EN officially debuted, but the core JP model hasn't strayed off far.
