>>659611https://holo.poi.cat/vtuber/cocoShe has the absolute wildest variance in viewers, probably the highest in Holo. You can IMO judge the real fans by who bothers to watch her do the most low-hype stuff like Superliminal or the zatsudans. She's easily 1/3rd deadsubs, probably close to half. Then again all Holos have some proportion of deadsubs, it's just hard to get a reading. Fubuki must be well over half, same with Gura. Korone has quite a few legit fans though, same with Aqua, and Pekora definitely has a ton of dedicated fans/hype.
Miko and Rushia also pull really high numbers despite being under a mil so they've probably got fewer deadsubs too. Generally you can spot a trend here - the more Western-focused/broken out a Holo is, the more deadsubs. Think Eekum Bokum and "a" and so on.
