Aliasing tenjinmon_kasumi to kasumi.

Reason: I'm confused about this one. I haven't found a source that says that her last name is Tenjinmon (that's her fighting style only).
So I think is better to leave her name as kasumi (or mass edit the tag in case another char named Kasumi appears).
That or alias kasumi to tenjimon_kasumi.

"Kasumi" shouldn't be a character tag by itself.

There is a base tag for the most popular version of quite a few characters. I can pretty much assure you that there will be no alias involving kasumi because it's such an ambiguous name, though.

That's why I said the thing about mass editing the tag (because Kasumi is too common). Maybe kasumi_(doa) will do the job.
I don't see the point of having 2 different tags for the same character.

We already have a lot more of her under just kasumi so I mass edited tenjinmon_kasumi to the single name for now.

As for qualifying it, we could do so, but it seems like a number of DOA girls got unqualified single names for having a decent number of images. I'm inclined to leave it unqualified for now, since every kasumi image on danbooru is also tagged DOA right now. kasumi_(pokemon seems to have already gotten a qualifier.

I suppose that if we had multiple Kasumis (or whatever) one would technically not need a qualifier. BUT, if we don't qualify all of them, then you don't get this:

Maybe you meant: kasumi_(doa), kasumi_(forgetmenot), kasumi_(pokemon), kasumi_(suikoden), kasumi_(super_real_mahjong), or kasumi_rose

So I would prefer there to be a qualifier.

I would prefer we change how ambiguous tags work, first. If a tag is ambiguous, you should get that whole list of "maybe you meant..." regardless of whether the tag in question has images under it.
