VTuber group "BEASTIEZ" as a copytag

Should their be a copytag of the VTuber group known as "BEASTIEZ"? I feel like it should be made as it's the same manner as Densetsu.EXE.

I was wondering why it didn't have one, actually, it's never been a requirement for something to be an official agency to have a copyright tag. Groups like this have them often enough.

Same as I said to you elsewhere: I hope you'll realise you answered your own question.
