>>103901680Someone that's an indie like skye and graduates is mostly going to go corpo so restricting your search to small corpos is really easy. Double easier if you are /here/, you can just let /corpo/ OPs tell you about new debuts.
For the other way around (corpo to indie) it's a bit harder yeah, but you basically stalk your girl's social circle for new vtuber twitter accounts appearing. If your oshi's genmates have alt indie accounts you stalk those. Failing everything you stalk their mods and/or top paypigs to see if they found out about a reincarnation. And if that fails you check relevant imageboards threads to see if your oshi has been found by an anon.
Not knowing these tricks just means you are a bit new to vtubing and that's okay.
