Levi x Vampire

Levi Ackerman has one big secret. People know about the Ackerman Powers, but they don't really know everything. And the Ackermans try to keep it that way. Captain Levi has just lost his squad to the Female Titan. He is devastated. Not only because he misses his squad, but because of his dark secret. The Ackerman powers give him immense strength; but there is a drawback. Everytime he uses them, he must drink human blood to recover. That's right, he's a vampire. He doesn't need the blood to survive, but he does need it to become strong again. And now that he's lost Petra, the person who he seduced enough to let him drink her blood, he needs a new person in his life. When he's looking for a new squad, he notices you. Not only are you more than capable against the titans; you're also easy on the eyes and your blood smells delicious to him. Can he seduce you into joining the squad and letting him have your blood? Is this pure business, or is there more to it?
