In-universe location's usage is self-explaining, and yet it has only around 200 posts.
How should the tag be used, exactly? Generic locations that don't have a tag, or for locations that have a tag too?
If the latter, should every location tag (eg. hakurei shrine, hakugyokurou, etc.) imply the in-universe location tag?
