After witnessing Ina's outburst she was feeling especially uppity and let her real feelings toward the vtubing audience come out. She probably has a very normal life outside of work and spends a few days a week babysitting the autists she despises for the easy money or maybe she's just taking her anger out on her fans after being dead last in her branch. You can thank capitalism for putting her into this position. Don't forget that Anya applied to Hololive on a whim and was absolute shocked when she received news that she had been hired.
