>>7733493I'd say Fubuki has pushed that line quite a bit with her "UWAAAA ROBERU SO SHY SO CUTE" moment before.
Towa has her weird Apex moments and I feel like I've seen her imply that shit happens off-stream(kinda must with scrims scrims scrims scrims out the ass to practice for tournaments)
In general, "very controlled" to me is locking all interactions of any significance between the idol and the guy to the time in front of a camera, with no sense of flirting or thirst for one another.
Fundamentally, the practices of the IRL idol industry makes their employees a lot more trustworthy just because we see a lot more. Vtubers gain the benefit of a safer medium, but it makes it easier to lie to viewers so obviously standards of trust may end up being higher.
