Katherine stayed by Master Ciel right side. Sebastian came in the room. He said " Master we are going to have a guest". Ciel said "Okay". The guest came in and it was two demons. I growled and Ciel said "Katherine hold it. " I said "Yes master. " My blue eyes change to a blood red. I close the curtains and lock the door. I walk back to Ciel's side. They change into their demon forms and so did I. I smirked and said "What do you think your doing." They smiled evilly and said "Killing Mr. Phantomhive here of course." I said "Shall I master? " My nails turned into claws. He said "Do what you like but keep it clean." I flew out the window and smiled at the two demons. I smirked and said "Too easy. " I snapped my fingers and a giant cat came and killed them. The giant cat left before Sebastian could see it. I cleaned up and said "Look at the time we would be expecting guests anytime soon. "
