Well Chaun, the other gif aren't tagged Aki Eda either for some reason, despite being an incredible look alike version of her work. Maybe it's in the rules I ain't aware of
Well the ZUN tag is a character tag, which would be incorrect to apply as the image doesn't depict ZUN. Also wouldn't it be incorrect to tag the image with the ZUN_(artist) tag because he didn't actually draw this, it's only a parody of his art style.
