I don't think Gura actually has the biggest opsec, though. Her immediate family, at least, knows who she is. Mumei hasn't even told hers anything beyond that she does youtube stuff, and she hides any sign of hololive stuff whenever a repairman or whatever comes by. Also, Gura has the shark/hololive merch shelf, but I'd be surprised if she has her giant play button with "Gawr Gura ch" hanging up on the wall where anybody can see it.Hmm I wonder why not try to stream in her PL then.
I guess that could be it.
That's interesting. Even Gura who probably has the biggest opsec had no issues accepting the play button.
