Kuroshitsuji and Fullmetal Alchemist crossover – Note – this fan fiction will skip between locations and characters.

London – The home of Ciel Phantomhive

The sun held high over the great city of London, all seemed well, or so I assumed it to be, but in the scorching heat something was stirring, evil was afoot, but its intentions were unknown to me. There was a knock at the door to my study, "Come in", I replied.

"Young Master, a letter had just arrived for you. I assume that you know whom it is from." It was Sebastian, my butler. Now he is no ordinary butler, indeed he is not; you see he is a demon, and well quite a good one at that. The letter was from Her Royal Highness Queen Victoria.

'My dear Ciel Phantomhive, I hope that all is going well for you, I am not sure if you have heard about the latest attacks that have been plaguing the city, the Yard has not been able to deal with the situation with enough haste so I am asking that you become involved. I am certain that this madman, although being human has the ability to perform alchemy. I don't know how much you know about alchemy so I have arranged for Edward and Alphonse Elric, to come and assist you on this case. I am sure that the criminal underworld is involved in this, and I hope that you defuse the situation with as much speed and efficiency as you did with 'Jack the Ripper', yours sincerely, HRH Queen Victoria.'

I didn't know where to begin, what is alchemy and how was it being used to kill people.

"Sebastian, as you most probably know, that was a request from the queen, there have been many attacks on the population and there is a high chance that the culprit is using alchemy. Now I have no direction as to which was to walk when it comes to this alchemy, to be completely honest with you this is the first time that I have ever heard of such a thing existing."
"Master Ciel, I have heard of the science of alchemy, but although I am gifted in knowing a lot of things I am afraid that I fail you as the Phantomhive butler on this."

"Sebastian, you haven't failed me, whilst I expect you to have a vast knowledge of the world, I do not expect you to know everything, now if I did that would be asking too much of you."
"So Ciel, I assume that someone will be coming to help us with the investigation. If so please tell me that it is not one of those Grim Reapers, such as Grell."

"No Sebastian, they are not a Grim Reaper, but I do feel that Grell might be of assistance somewhere along the line. Will you promise to get along with him, if I ensure that he doesn't try to annoy you in anyway?"

"Alright that's a fair compromise, but how are you going to prevent him from annoying me?"

"Well since the Jack the Ripper incident, Grell has been on what we humans call parole, he will be monitored and called back to wherever those reapers condescend if he breaks the conditions. Now Sebastian, if you would be so kind as to prepare a room for Edward and Alphonse, I don't know when they will be arriving exactly, but I know that it will be within the next couple of days."

"Yes my young Lord." And with that Sebastian went off to continue his daily duties and I set to work reading and checking invoices from the suppliers to the Funtom Toy Company. On the other side of the globe, Edward and Alphonse Elric were about to find out about their latest task.

Japan – the offices of the Military, located at Central

"Edward Elric, Colonel Mustang will see you now" the young budding new recruit beckoned me into the office and closed the door behind her. "Please have a seat." I sat down and eagerly anticipated the task I was to be given. I hoped that the task would be a decent one, unlike the last one which was to inspect some coal mines.

"Right Fullmetal, your skills are required in the City of London." Colonel Mustang stated

"London," I replied, now my geography is not the best in the world but I knew where this was. "That is in England, is it not?"

"Indeed you are correct, Edward. There have been a recent string of attacks of the population by someone whom has alchemical powers. Now Queen Victoria, whom runs the country, has requested that you go and aid a young boy called Ciel Phantomhive, whom is commonly referred to as the Queens Guard Dog, as the English have little knowledge of alchemy compared to us."

"Colonel, may I ask, why are you sending me on this mission, wouldn't it be more befitting for someone of your superiority?"

"Now, now Fullmetal, I would have happily accepted the role, but the Queen specifically requested that you and your brother attend, you will be staying at the manor of Lord Ciel Phantomhive, and yes he has been made well aware that you will be arriving. Now there is not much time to lounge about, you will be flown to England by private jet in approximately one hour and should arrive in a few days' time. When you are there, I expect you to follow Ciel's instructions to the letter as if they were my own as this is under his jurisdiction not ours. Ok."

"Yes Colonel," and with that I embarked on my journey to London. The plane ride was most boring and uncomfortable, but I was anxious as to what Ciel would think of me and Alphonse. For Alphonse is not your conventional human being, well some people wouldn't call him human, since essentially he was a soul in a metal shell, but I had a gut feeling that Ciel would accept us for who we are, but as the journey was long I drifted off into a dream and awoke to find myself of foreign soil, and Al saying that we had arrived in London.

London – the arrival of Edward and Alphonse.

"Sebastian, are you sure that it is the right thing to do, to have these two strangers help me in my investigations."

"Now young master, it is not me you should be taking up this debate with is it now, it is the Queen, and I doubt it that you would defy an order of hers."

"No, I guess your right Sebastian. Has everything been prepared for their arrival, they should have landed by now."

"Yes everything is as it should be. I have arranged for a car to meet them at the airport and then they will come to the house where I am assuming that tea will be waiting."

"Yes indeed, but when preparing tea, ensure that it is tea for two."

"Tea for two, but surely there are two of them coming to stay, and including yourself would make three, unless you are not going to join them."

"Now Sebastian, you know that I would never pass up on a cup of tea. The younger of the two Elric brothers, Alphonse, I am afraid to say is just a soul in a metal shell, I am not sure what actually happened here, and I do not want to pry into their past. That is why we want tea for two, by all means make extra, I guess that it might get eaten in the end. Ok."

"Yes my young Lord."
