Recently I've been craving a good reverse harem.
Now there aren't too many threads for this, but the few that I have seen aren't exactly what I'm looking for.
Obviously the request for a reverse harem is pretty self-explanatory, but in additionto this, I would also like, vampires, werewolves or anything supernatural that would give it a twist and spice it up.
Also, could there be a fair amount of varied male interests, like not just copies of each other, and more than just three or four.
Lastly, please let the main character be a bearable, strong female lead, but not (too) rude and loud-mouthed as well.
Thank you in advance!
P.S, I've already watched Diabolik Lovers. . , But thats an anime so I'm not really sure why I mentioned it . . . anyway, bye! 😀

1-nen 5-kumi Ikimono Gakari comes pretty close to your request, but there are only 3-4 love interests. In Charon Siphon, the MC works at a cafe run by demons (many of whom are also love interests.) You can find more by searching the fantasy & reverse harem tags together, like this:
