Vampire otome is the genre's thirstiest lane, and also the one where honest availability info matters most. Every ranked pick here has a verified official English release you can actually get right now - which is why Diabolik Lovers is absent: none of its games have ever received an official English localization (only fan patches exist), and the Dance with Devils game likewise never left Japan. One more note before the biting starts: this corner of otome trades in blood-taking, captivity framing, and consent-adjacent tension, so read the content warnings on each entry - they are part of the recommendation, not a disclaimer.
