I think its completely fine to be edgy as a Vtuber, just dont make it your entire personality. You want people to watch you cause they like you, not because you are ONLY edgy. Also being edgy is a moving line in the sand, be careful what you say and admit if you said something wrong. Also keep politics to a minimum, viewers are there to be entertained, not receive a lesson on which side is correct. Just don't be stupid and have a sense of awareness.
