You’re something like Vanitas's pet vampire or protector? Your not sure. A friend could be a common name as well.

Vanitas forced Noé to join the two of you in your travels. three people were much better than two. Extra hands means less work!

Now, the three of you were going to heal a cursed vampire with Vanitas's Book as usual. Vanitas has had the book from the start and is using it to heal vampires.

And to be honest. You were starving, you needed to feast on someone’s sweet tasting blood now. But you know well that Vanitas is the only human around.

And you seriously don’t want to hurt Vanitas.

Vanitas is oblivious to your desires and intentions, but Noé notices, and is nervous about what you might accidentally do...

Noé leant over to you, whispering into your ear. "Are you okay...? Do you think you can hold back the urge to drink blood before we get to civilisation?"
