>>61522113It's not that deep, it's just that a lot of girls have no idea how to take care of themselves. Let's consider Hololive for a moment in this example.
1. They don't exercise (despite eventually having to dance), Even people who don't have to dance should also be exercising regularly so their bodies don't become weak.
2. They don't eat right and don't get enough nutrition. They're consistently eating like shit or eating garbage.
3. They don't sleep right. Every single one of them has a fucked up sleep schedule, the JP girls aren't immune to fucked up sleep schedules even though they live in Japan.
4. So many of them are putting on a voice that their throats are getting absolutely fucked, and not in a good, sexy way.
In a nutshell, they suck at getting their shit together. But as we all know, mental cases like these girls make for generally good vtubers.
