She debuted after Siro but before Kaguya Luna and Mirai Akari, and was an underdog from the very beginning. Sora infamously had only 13 viewers on her first stream and gained her first few hundred subs through a combination of herculean effort and dumb luck. Compare this to today, when every new member gets 100k subs before they even debut. It is not exaggeration to say that she's arguably the person most responsible for building Hololive into the success that it is today, which is why Polka responded that way and all of the other members act like she's the Virgin Mary of the virtual world.
The really hilarious part in all of this is that Sora allegedly became a vtuber almost by accident. Supposedly, she was originally picked up with the intention of merely being the voice of the Cover's mascot for some AR app they were working on; however, between having little in the way of actual work due to Cover being a bunch of nobodies at the time and the appearance of Kizuna Ai, she and A-chan started streaming and wound up becoming part of history as a result.
