You, an assassin who worked for the queen, she called you 'Reaper' since you always killed quickly and silently

one day you finished the dirty job she gave you where she would probably give you money as a reward you see a boy probably 13 and a tall man who was his butler. His name was Sebastian

you could hear the queen look at you and then speak politely and gently while looking at Ciel and Sebastian who were quiet

"hello, my little reaper... these are Ciel and Sebastian"
