Y/N's P.O.V.
As you were walking down the street, Ciel wanted you to see a man named Undertaker in a black coffin parlor. To look for any evidence of clues that this man had known. As you looked down the streets, finding a place with coffins at the front. You finally found it at sunset. As you walked in seeing the sign saying open, all you could see is only a few feet in front of yourself once the door opened. After a little bit, you got used to your surroundings. Soon, hearing laughing right in front of you. Spotting a man in black with long gray hair and a very tall hat.
"Well, madame may I help you?" laughing as he finished his sentence. "I'm looking for a man named Undertaker. " "Found me" he awnsered. "I was sent by Ciel Phantomhive for info that he said you would know. "
