I really loved idea, that Rin is Haru's butler and i thought about it as Kuroshitsuji AU, but not in the same way as Kuroshitsuji is. This story line is in London, they live in great mansion and Rin is a demon. (But he's not like Sebastian xD)
Hope you like it :3

"Rin! Where's my newspaper?" I shouted because I was really bored and Rin wasn't in the same room.

"Here, master." he replied and gave me news. I still wasn't sattisfied. Well then, I just read it and then throw it away.

"Ten murdered men were found on the Trafalgar square with both eyes cut out." This sounds interesting, I thought and started to read article about it on the next page.

"As we know, they were from the same company, which was a rival to Nanase's. It weird, that they were here, all of them, because every one of them had different work time. And the bodies show signs of brutal murder. This is what we can say right not. We'll investigate this case…" So they were our rival, right?

But what happened?

"Rin! We're going to town, get ready."

"Yes, master."

At my other house, near to Trafalgar square was my another servant, Makoto. He was quiet all the time and I honesly thought, that he can't talk.

"Good afternoon, Makoto-san." greeted him Rin and I just nod. "I'll make tea, master."

"Well. We need to investigate this case, too. What do you think, Rin?"

"Certainly." answered Rin and I smelled nice aroma of tea. "Here, master." gave me Rin one cup and stand back.

I drank it and then we started to collection informations, we had in newspaper. Who did this and how?

"Rin. You go and investigate it in Scotland Yard, you understand?" I ordered him.

"Roger." and… he was gone. I started to read a book and I was thinking about case, when someone knocked on the door.

"Makoto." I said, bored to death, just sitting in my armchair.

"I heard you are here, my dearest friend!" someone said sweetly.. I turned my head and saw Nagisa. He was my bestfriend, when I was living there with my parents. But they're dead and I moved to my mansion far away from centre. "How are you? I haven't seen you for a long time~."

"Fine, thanks. What about you?" I answered with "I-don't-want-to-talk-to-you" accent and smiled a little bit.

We talked for a hour, because Rin still wasn't home and Makoto wasn't talking.

"So, I'll go~. You need to visit me in my house! I sure need to introduce you to my wife. Bye~." and he was gone.

"Master." whispered Rin to my ear and I, shocked, turned to him. "I insvestigated it, and I also have this letter, from Queen." he said then.

"Okay, give it here." I answered, sat down to armchair again and started to read. I was shocked, because Queen wanted to see me. "Rin! Tomorrow's morning we're going to see Queen. Make preparations!"
