I fucking love gambling with my sanity on the line I will NOT read the tags I will NOT make educated decision I WILL reap what I sow!!!! (This was one was decent)
So I just found out that the vampires in this world have the ability to give birth despite being male…
Rose’s “mother” fell in love with his servant, and used his “magical powers” to give birth to Rose and Rouge. So technically, vampires in this world are both male and female, meaning Rose can also give birth despite being male. How that works? No clue but fiction is fiction.
(here come a short leçon in yaoi culture)
It borrows from a trope/ subset of yaoi called "omegaverse", in which the population is sorted into 3 categories: The alphas, typically dominant and masculine, usually at the top of any hierarchy; the betas, that are your run of the mill random guys; and omegas, which are the counterpoint to alphas, they're (usually) meek and submissive, can get pregnant from sex (we're talking male on male pairing here), and borrow some animals characteristics (they go into heat, emit pheromones that attract potential mates, etc).
The omegaverse setting has its own tropes and problems (it glorifies/fetishies toxic behaviors and relationships at times), but if you find a gay manga where one dude end up pregnant, (assuming it's not about a trans person having been grafted a womb or something) then chances are it comes from there.
This is peak. Don't dwell on the gay thing, I assure you, you won't come to like masculine men just because you read this. I personally am gynephilic and I say that vampire looks 100% female. Not even a hint of maleness.
But if you feel attraction towards the raul instead of the vampire, I am sorry but you are gay bro.
