Review Detail of corales in VAMPIRE COUNTESS: REINCARNATED!

This is early so I'm deducting a point for world background. The countess background is half-revealed. But I don't know much about the world they live in. I can't clearly picture the setting and map yet. The good thing is, I like the characters so far. I thought the development of things would be slow, but it's surprisingly not. I'm still waiting for the actual revenge to start though. Anyway, good story so far
