@Sani omegaverse stories are actually fantasy stories and actually have some basic plots which needs to be followed to make sense. I don't think you can find a vampire story where the vampire stays vegetarian and doesn't crave for blood all his life because that ruins the plot. The basic concept of vampire fantasy is having a vampire-who-looks-like-man and sucks blood. That's the basic plot. Messing up the basic plot might still create a wonderful story but that doesn't mean the story plotline is correct.
