Both are manga series with dark and gothic atmosphere, focused on the topic of vampirism and everything that is related to it (i.e. demonic superpowers; vampires' minions, like werewolves; etc.). They have somewhat similar looking art styles, even though they belong to different series and were created by different authors (although I am aware that it might be just me seeing them that way).
