A solo Virtual YouTuber who is not affiliated directly with a (major) corporate group, and is thus independent.
If the indie Virtual YouTuber(s) in question is:
part of a broader VTuber group consisting of at least one more VTuber, the copyright tag instead would be that of that given group, to account for the (hash)tags that the individual character tags couldn't include under their wiki's Other Names;
sharing a channel with at least one (1) more VTuber, the copyright tag would be of the channel instead, for similar reasons as above;
under a corporate support group (i.e. VirtuaReal Link, etc.), depending on the circumstance, they receive their own copyright tag, due to the nature of their affiliation with said corporate entity and the potential for them to just leave it if they wanted to;
This tag can also alternatively serve as a pseudo-original tag, allowing one to use both the relevant request tags, if they are uncertain about the VTuber and their affiliations.
