I can't see it from http://kyra-ojosverdes.livejournal.com/tag/ in the list. When I try to go to http://kyra-ojosverdes.livejournal.com/tag/raven directly, I get the following error message:

Error
Sorry, one or more specified tags do not exist.

So, even if you're guessing at a tag you can't see, it pretends there's no such thing. There might be some deeper way of retrieving everyone's tags for everything (I can ask my geek filter if you like; I know there are some things that can be pulled out of public databases that aren't available through the Web UI), but at least it's not trivially available.
