As I was tagging a new character I was thinking she should really have a qualifier to be safe, but then I was like "what the hell do I use in the first place?" Most of the stuff just gets copyright tagged eien_no_aselia by default even if it's not related to first game, and then you have Euphoria who has _(seinarukana) as her qualifier, some Seinarukana posts are tagged with both copyrights, basically it's a total mess. I was thinking there should probably be an eternity_sword_series copyright tag to cover everything and _(eternity_sword) could be the qualifier for any character who needs one.
On the other hand it's not like there's that many posts (and mostly official art) so I'm not sure anyone would care if we just kept using eien_no_aselia as the overall copyright tag. But it seems weird to use _(aselia) as the qualifier for a character who has nothing to do with her game.
