The Blood Princess Master Who Faked Her Death Wants to Avoid the Saintess

My name is Veiloria. Originally male, I'm a transmigrator. The good news: I transmigrated into the body of a Vampire princess who appears once in a millennium—so powerful I have no equals. The bad news: the apprentice I casually took in over a decade ago while disguised as a human has now become the terrifyingly powerful Holy Maiden of the Silver Radiance Holy See, and is currently hunting me across the world with her Holy Sword. Even worse news: she just leveled my hometown. Now, disguised as a broke human, I wait tables at a nightclub and scrape together money, scheming over how to break my unreliable, thrill-seeking mother out of the Holy See's prison. Then my resentful little apprentice suddenly appears before me in Glamour: "Little sis, working at a nightclub is so dangerous—come work at the Holy See instead. Full benefits package, and I'll have your back." I stared at my nearly-depleted stock of blood bags and my bank account balance of zero, and fell into deep thought. This offer—should I take it, or not? …… My name is Ximilita. After Master died, I spent 10 years becoming the Holy Maiden of the Silver Radiance Holy See—all for the sake of vengeance. I swept across all 7 continents, burned the Vampire Capital to ash, and finally had my revenge. Until I found the Vampire princess's diary. It turned out the person I had regarded as the light of my life—was a Vampire. It turned out the cause I had burned 10 years of my life avenging—was her homeland. I hate her to my core, and I've been searching for her to the point of madness. Until, at a nightclub in the capital, I encountered a server. Her eyes always shifted away whenever she looked at me. Every excuse she gave for turning me down was full of holes. Yet she carried a familiar scent that put me at ease. I smiled and extended the Holy See's employment contract. This time, no matter what you are—human or ghost, Vampire princess or destitute girl. Master, this time, you won't escape. — Description from novelcodex.org
