If I Can't Drink the Strongest One's Blood, I'll Destroy the World

I'm a noble pureblood vampire, and I love drinking the blood of the strong. So when I realized the person in front of me was powerful, I asked to drink his blood. "If I don't drink blood, I'll starve to death. Before I die, I'll turn everyone in the world into vampires!" Under my threat, I successfully drank the blood of the silver-haired man in the blindfold. His blood tasted great, but I still wanted to drink the blood of the strongest person. I'm a greedy pureblood, after all, so I asked him who the strongest person in the world was. "I'm the strongest," the silver-haired man replied with a smile. I see. No wonder I was so full after drinking his blood... Except, no! I'm a noble pureblood. Someone as noble as me should have plenty of walking blood banks, just like my descendants. But ever since I drank the strongest man's blood, he keeps thwarting all my hunts! I'm furious! Even though I've already tasted the strongest man's blood, I'm still going to destroy the world! >> Satoru Gojo. Only the strongest can stop this idiot vampire from drinking other people's blood. >> I'm good at OOC and procrastinating. Lots of creative liberties. >> The noble heroine is an innocent, nonhuman being (?). The setting is based on an old vampire manga. Theme: Can a noble vampire fall in love with the strongest?
