nuke imp
A tag exclusively for that goblina of Zelda; tagged otherwise for it's misleading other name 小悪魔 meaning 'little devil' in the literal sense. Even if imp happens to be usually translated to 小悪魔 it is an unproductive folkloric distinction for the topic at matter, specially for something that does not have a consistent depiction and it's faithful ones look nothing like Midna.
Considering there is midna (true), midna (imp) could be an enhanced replacement for this tag.
To be fair to everyone I do acknowledge the same could be said with oni and shuten douji, however the tag makes sense for the diverse and massive set of oni girls which doesn't work for a tag this erratic.
Most of the posts were gardened to demon_girl, demon_boy and demon save for these imp -midna -demon_girl -demon_boy -demon which were too ambiguous for me to tag.
Repurposing the tag for the dictionary definition of 'imp' is fine, but I don't presume there's that much interest
