That doesn't change my point though; the vocals (Miku, VY2 etc) can sing about a character in a song which isn't themselves (BRS, Roro etc). Another more popular example would be the Kagerou Project where you have IA and Miku singing about a whole bunch of OCs.

The concept has been around for a long time in this fandom so I don't see how people can't apply such logic here, especially when it's been explained by Tsukasa that Roro is an OC.
