A House Without Fangs

She falls asleep one night and wakes up to find herself transmigrated into a historical fantasy world as a Vampire. As the 7th-born of one of the last remaining vampire families hiding amongst human high society as trusted advisors and destitute noble families, she must endure in an era past the former glory of vampires. However, during her awakening, she experiences many changes that set her apart from the other Vampires of this era. She was born to be a ruler, not a servant.
