Akame and Akashi answered,"Even if our human blood is replaced with animal blood, and we think it's human blood, our body will detect it. If we don't have human blood, we will experience extreme bloodlust and turn into Level Z vampires which we all categorise as 'dead'. Level Z vampires are out of control and will go around killing humans and every living thing in sight."
Akame and Akashi noticed that Sam had figuredout that someone was watching them. Akane told her,"That guy over there, eating lamb." Akashi continued,"He's a werewolf, from the smell of his blood."
Akame and Akashi saw Sam stand. Finishing up the last of their blood and lamb, they stood up and followed Sam. "What did you say about Level Z vampires?" They asked,"We heard that."
Akame and Akashi watched him walk away then looked at each other shrigged,"What did we do wrong, it was just a joke."
