Hello!!!!
Is there a noticable difference between stories that use the multiverse tag and stories that the omegaverse tag?
Multiverse is typically when multiple different settings, i.e. different universes are put together into the same setting of the story.
I suppose a possible example could be that anime where they crossed over characters from KonoSuba, Overlord, and some other isekais.
Omegaverse - also known as ABO-verse - is a setting where everyone has a secondary gender labelled as: Alpha, Beta, Omega
It isn't restricted to being BL, and it doesn't have to involve anything sexual.
It can be GB, it can be GL, or BL, it's up to the writer.
As for what these secondary genders pertain to, it's extra biological traits other than male and female.
It originated from BL werewolf stories but has expanded into something far more.
You can technically have both tags for a story if it includes the aspects of both. However, the two tags have nothing to do with one another other than that they are a -verse.
