MNT said: Is there any way to make "World is Mine" a tag?
What I'm wondering if there's enough fanart of it to deserve one. The way "Black Rock Shooter" does.
Well the creator of the 'black rock shooter' video is making a manga so it can have it's own tag while 'the world is mine' has no plans to become any form of series.
Tags aren't for denoting a series, they're for facilitating searching. If more than one person wants to find all "world is mine" images, a tag for it makes sense.
