The above Umamusume characters are named after real-life horses so by usual convention they should take qualifiers. Most other Umamusume characters already have qualifiers, and Pixiv/Nico/etc. also regularly use qualifiers to distinguish these characters from their racehorse counterparts.
Satono Diamond is hovering close to 200 posts, so going for alias instead.
This is separated from the previous BUR (forum #192944) because there's an issue with the spelling of Tannhauser's name that is still not resolved yet. See topic #19006.
I think it's okay to proceed with a rename to add the qualifier, and only consider whether to alias Matikanetannhauser_(umamusume) (without the space) later on.
Separated from the above BURs to avoid clogging the posts.
This should cover all the named horse girl characters without qualifiers in the list_of_umamusume_characters. In case I missed anyone (in or outside that list), would appreciate it if they can be mentioned so I can add them to the first BUR.
If it's a better idea to use aliases instead of renames (I think most people would expect qualifiers anyway, but I'm not sure how popular those specific Umamusume char searches are on other boorus), I can change all the entries in the first BUR to use aliases instead. For Tannhauser, I'd prefer to use a rename in case we need to add another alias down the road once topic #19006 is resolved.
As for the list_of_umamusume_characters... don't think human(-seeming) characters with full names (or [job title + name], or [nongeneric descriptor] + [job title]) need qualifiers, but eh, removing them like for Akikawa Yayoi (Umamusume) isn't high on my priority list. Though removing it does have the benefit of making clear that Akikawa Yayoi is human(-seeming) instead of being a horse girl.
There are also some 'original' horsegirls with different names compared to their real-life counterparts, so these probably don't need qualifiers either, strictly speaking, but I'm more in favor of retaining these compared to those for 'human' characters.
