It's quite ironic, to be honest, and that's why I love it. They also make it clear that what they have going on isn't inherently romantic; it's solely based on using one another for their needs and wants. Love the physiological stuff. They don't gloss over it. The vampires are portrayed as these monsters, while Yamadera is the actual monster, all while being the only human. Even in conflicted situations (like in recent chapters) with vampires who could easily rip his throat out , he still holds some power in the situation, if you will. When I think about it, if he were to become a vampire, things would most likely hit the fan.
I love how everyone keeps telling yamadera that there's something fundamentally wrong with him like he's the monster and not these vampires.
In that vein, Yamadera who is human but acts more monstrous than any of the vampires and sayo who is a monster by definition but is still a caring and compassionate person who is filled with love. It's why their dynamic makes the story so exciting, I can't wait to see how their relationship will evolve (if it will ever)
