>>3185799If you're into this sort of thing you can just pick most any, you can just navigate the videos on her channels and click whatever's popular for starters. I say channels because there are quite a few great ones in A.I. Games as well, though you'd need a lot of free time to go through them.
You can also check
>>>/wsg/2268740 for bits and pieces of videos of many Vtubers. Ai-chan's just the tip of the iceberg.
There's also a thread in /jp/, but they mostly discuss small to medium sized channels. If some catch your eye it's probably the best place to discuss them.
