In Black Butler as viscount Druitt, this should be fun.

Part 1

Johan POV

It's been 16 years since and now I'm a 23 year old Aleister Chamber, at the start of the Black Butler. When I first woke up in this body, it turned out that the real Aleister Chamber had fallen off a tree and hit his head (probably causing him to die) and thus I had no problems with playing the amnesia card. During the 16 years I have been here, I carefully crafted a reputation for myself, that being the exceptionally smart gentleman of the high society.

I graduated from the Weston College from the house of the Sapphire Owl and then got a license in the medical field, following the original's footsteps in the latter. 'It was a pain, but I need Ciel to suspect me for being the Jack the Ripper, otherwise it'll be boring.' In conclusion, I was mostly living like the real viscount Druitt. Well, on the surface anyways. What people didn't know, is that I had created an underground network, basically having my eyes and ears almost everywhere. This in particular also led me into meeting the famous Undertaker and it turned out that we had a lot in common, 'Though it shouldn't be too surprising, we are colleagues in a sense, after all.'

Today, I'm holding the last party of this season. From what my sister had told me once, although he's not Jack the Ripper, the viscount was a human trafficker and would bring the ladies he seduced into the back room, where he'd proceeded to kidnap them. I don't do that here, so I'm not sure whether or not Ciel will suspect me for being a killer.

I had two man servants help me get ready. They dressed me in a mute purple suit and an elegant white coat with black and golden accents, tying my long hair into a ponytail to the side with a black silk afterwards.
'His appearance was probably the only redeeming quality of this man.'

The suit (yes, it's Ijekiel's from Wmmap):

Thanking them, I made my way over to the party, which had already begun.
'Let the fun begin.'

Ciel POV

We were all inside the carriage aside from Sebastian and Grell, riding to the viscount's party. I had, for some reason, a female disguise on.
"Ciel, are you sure it could be the viscount behind all these murders? He seems like a perfect gentleman. It feels absurd." Madam Red questioned me, furrowing her eyebrows. I huffed at it, "Yes, he does seem like the perfect gentleman, but he has the required skills to perform such a surgery on the victims, which makes him one of our suspects. Not to mention, he's too perfect. That in itself is suspicious."

That's right, his reputation was too good to be true. Even if he wasn't actually Jack the Ripper, he must still be hiding something, and I would be lying if I said I wasn't curious. "Change of topic, why do I have to play your niece?" My cheeks were red from embarrassment, it really annoyed me to no end.

At this, both Lau and Madam Red giggled (more like cackled). I could also hear the chuckles of Sebastian at the front. She then gave me a close eyed smile, "I've always wanted a girl ^_^" beside her, Lau was losing his sh!t.

"That's your reason?"
"Well, you wouldn't want them to know that you're the queen's guard dog, would you?" Lau intervened. I didn't argue further, I just hope that no one recognises me.

We finally arrived at the party, with Sebastian escorting me inside. And to my dismay, I heard a very familiar voice nearby, "Oh, that dress is so cute!" Both me and Sebastian slowly turned to the voice. 'Elizabeth?! Of all people, I don't want her to see me dressed like this!' Thankfully, she was conversing with other guests, "Young miss, we'll take this opportunity to-" Both me and Sebastian hastily turned around and walked off to the other direction. From the corner of my eye, I saw the viscount enter, immediately being surrounded by people. 'There he is!'
"There's the viscount-!"
"That girl's dress is absolutely adorable!" Elizabeth shouted, pointing at me. 'Goddamnit!'

While running away, we hid behind a big cake. Going to Madam Red was not an option, as she seemed to be reliving her old days with a bunch of men surrounding her. The viscount, on the other hand, was on the other side of the party, chatting with some of his guests. He caught me staring at him, sending me a brief smile.

Suddenly, Sebastian grabbed my arm and lead me to the dance floor, "We have no choice but to use the dance to get close to him." We danced for a few minutes, surely moving over to the viscount. It was more exhausting to dance with a heavy dress than I imagined. Thus, in the end, I was collapsed on the floor, breathing heavily.

"Are you alright, young lady?" I heard a gentle voice say, a shadow loomed over me. When I looked up, I saw our target standing before me, smiling softly and holding out his hand.
"Y-yes, thank you." I immediately played the role of a naive young girl, taking his hand gingerly. He gently pulled me up and handed me over a glass of water. "I must say, that was quite the lovely performance from the both of you, just like a pair of swans." He then turned over to Sebastian, "You were quite exceptional in leading the dance, my lord."

Sebastian smiled sheepishly at him,waving his hands. "I greatly appreciate your compliment my lord, but please, there's no need to address me so formally, for I am merely the tutor of my young mistress." The smile on the viscount's face widened, as if having accomplished something of great significance. "Is that so? What is your name, if you don't mind me asking?" He was weirdly respectful towards someone he thinks is a mere tutor, it was strange.

"My name is Sebastian Michaelis, my lord." Sebastian simply gave out his business smile.
"Very well, sir Michaelis, it seems that I have already found a tutor for my future children, if you would agree?"
'Something is odd about the way he just toned Sebastian's title.' I didn't dwell too long on it, though. There's no way he could have known about our real identities. "It would be my pleasure, viscount."

"Oh! Where are my manners, my name is Aleister Chamber, also known as the viscount von Druitt. My apologies, my lady, I almost forgot to ask you your name." His gentle smile turned into an apologetic one as he turned back to me. 'SHIT! I forgot to come up with a name for myself!'

"This is my lady Narcissa Dallas, the only niece of lady Angelina Dallas." Thankfully, Sebastian was quick to come up with a fake identity, but when I looked at the viscount's reaction, I saw his eyes narrow, 'What is he thinking about?'

"It's my pleasure to meet you both, how is the party to your liking so far?"
'This is my chance!' I quickly grabbed the opportunity to move on with the plan. "Well, this party is spectacular, my lord, but I can't help but be bored by the idea of just dancing all night long." I gave him a pitiful look and stepped a little closer.
He simply raised his eyebrows, still smiling, "Well, we can't have that now, can we? I'm not sure if it would be to the lady's liking, but I have a library with a grand piano in it. I could escort you there, if you don't mind. Would you like to accompany us, sir Michaelis?"

Things were going a lot smoother than I imagined. I gave out a discreet signal for Sebastian to follow us in secret, so that the viscount hopefully had his guard down and so that Sebastian could interfere whenever needed. He understood and answered quickly, "Thank you for your kind offer, viscount, but I have spotted some close acquaintance of mine, whom I haven't spoken to in a while, so I would like to catch up with them." The viscount simply nodded his head, "Very well then, I hope you will enjoy the rest of your stay here, sir Michaelis."
"Thank you, viscount."

With that, we made our way to the library at the back of the mansion, 'At least that's where he said we'd be going.'

We arrived in the library and it was massive, with hundreds of books lined up in rows of shelves. In the middle of the room was a sofa and two armchairs on its each side. Behind those stood a grand piano, in front of a massive window that led to the balcony. 'It definitely wasn't cheap here.'

I suddenly heard the shut door lock behind me. Turning back to the viscount, alarmed, I found that his previous ever-present smile was no longer present. His narrowed violet eyes glowed in the dim light, looking down at me.
"So, how can I be of help to you, lord Phantomhive?"

'HUH?!'
