I thought the dqd would have known i mean he did it when he was alive and he knew ciel would take over so yea because one episode Vincent phantomhive said "ciel will take over when me and my wife die tonight by the Queen but u must not tell him" so yea
not to be rude but.... if anyone watched the book of circus arc, they would know that ciel's dad was like that too. He was running the underworld of England and dealt with stuff like that, maybe even killed.........................................
Fact : one hell of a butler is just a short version and less scarier of one demon of a butler Please don't comment me cause of a reason I don't want to talk about the reason
i just need to get this out my system (so dont judge me), i really think Sebastian and Vincent are twins like ciel and his revived twin, but the real Vincent was turned into a demon or the younger twin was turned into a demon, idk really know i just need to say this lol OvO
