A few months ago, the tag monmusu-quest was created. This appears to be for the VN "MonMusu Quest". Just now, I created the tag monmusu for the anime Monster Musume no Iru Nichijou (because the full title was longer than 25 characters, and this is the standard abbreviation).
Are these two things in any way related? Should they share the same tag?
If not, somebody who knows stuff about these two series should put a bit of disambiguating information in the tag wiki excerpts for future reference.
(I would research this myself, but, you know, spiders.)
