Doki's basically a brotuber and hard to call a girlfailure since she's pretty competent at anything that's not math or reading related. Mint fits everything, but if you're not into music or idolshit, that might filter you.
If you're fine with corpo, it's absolutely Shiori. She's the girlfailurest of the girlfailures and tends to be so isolated she's effectively indie. She's got some of the best zatsus in the industry, and is incredibly entertaining because she's always fucking around with her model, assets, etc. The only reason I don't watch her more often is because she does so much outlandish shit that I have a hard time finding time to actively pay attention to the stream. She's not great background noise because of it.
