You made a pact with Ciel allowing him to be your master and you to be his witch maid.

You, Sebastian and Ciel your master are in a ship called Campagna for a mission. Dead people in the Campagna started to grow more and more. You got separated from your Master and his Butler Sebastian,so you were on your own with the dead people. You were bleeding from fighting them. You wondered how many dead people you had to fight and how did they get here in the Campania since the staff won't allow them.
