This is my first review after reading the 9 chapters that are currently up.
writing quality: 4.5: The writing has some minor errors, but they're not that bad, just enough to notice but not affect the reading experience.
story development: 4.0: I give it a 4 because the premise is promising but it's too early to see if it will turn out good, so far, pretty good.
world background: 4.5: I'm really into dark fantasy, you know, demons, vampires and all that stuff, so this seems right up that ally.
character design:4.5: the title says it all.
updating stability: 4.0: too early to tell if we will get 9 chapters a week, like the author says.
