I think the part where their vision diminishes in sunlight is wrong. Never see that happening in games.

And it's anime. It's not going to follow traditional tropes of vampires and can twist them to their own liking for character appeal or plot. So yes, daylight, rosarios and garlic is not going to work on the vampires of this verse. But they can get killed and hurt normally, though silver has a potent effect (it poisons them, as seen with azusa's case)
