Reincarnated as Aleistor Chamber's Sister?! (x Reader)

(Y/N) (L/N), one of the many people who had been interested in Kuroshitsuji, also known as Black Butler. She was a person who disliked some characters while liking the others. And one of those who fell into the dislike category was Aleistor Chamber.

God has a sense of humour by assigning (Y/N) as the eccentric Aleistor's sister. If only she was someone like in a fanfic and was Ciel's maid. That would be much easier...
