It's hard to know what to do with them sometimes, because I like to have our tags be somewhat in line with Danbooru's character tags but at the same time there's so many Fate characters and versions of those characters.
We could give them her real names and when you searching for a tag there are sometimes suggestions where the other tag is written on the right side. Hard for me to explain sorry. Just tipe jack_the_ripper in the searching area and you know what I mean.
Yeah, those are called aliases. That means a character was tagged as something else before.

...I think I might do it.

Edit: I have done it.
