This Couple is unusual
Synopsis: You and Satan are currently hyper-fixating on the human worldâs Victorian-era and True Crime. Since your birthday is coming up, you ask Barbatos for a special gift - a trip to Old London to find out the culprit behind the Jack the Ripper case. Who would have thought youâd met one Hell of a Butler? (Kuroshitsuji x Obey Me! Crossover)

Prologue
cw: none
You and Satan sat hurdled together in his room, a book in each of your hands. It was quiet, only your calm breathing and the occasional rustling of a page being turned filled the room. It was pleasant. The other brothers knew better than to bother you two when engaging in your weekly reading session, only Lucifer forced the both of you to eat when lunch or dinner was ready. The two of you were currently inhaling the Sherlock Holmes series from the human realm and after finishing the current edition youâd usually engage in various discussions. Occasionally, Simeon was part of your little book club, being a writer himself, but he was sometimes unavailable when Lord Diavolo called for meetings and such.Â
âDid you know that they never solved a famous murder case in England in the 1800s?â You threw the question into the room when both of you closed your editions at nearly the same time. âHuh, I think Iâve heard about them. Jack the Ripper, if Iâm remembering correctlyâ
You hummed âRight, itâs one of the most popular serial killer cases that is still unsolved. Victims were all women, prostitutes to be exact and they were mutilated from the inside, really nasty if you ask me.â
Satan nodded curtly âSome humans are definitely up to par with our kind regarding violence and brutality.â
âTrue, true. Still, I am strangely fascinated by that mystery. Makes me want to travel back in time to solve it.â
A pause.
Satanâs lips curved upwards, a mischievous glint in his eyes. âWell, I think there could be a way. If we can manage to persuade a certain demon that is.âÂ
âNot fair, I wanna go, too!â Mammon hollared, glaring daggers at his blond younger brother. Satan, joined by Belphegor, rolled his eyes at his antics. âLololol, Mammonâs being desperate againâ Leviathan snickered while the others decided to ignore the Avatar of Greedâs tantrum altogether. Everyone knew he was interested in swiping up valuable items from the past to sell as authentic antiques in the present and being jealous on top of that.Â
âSorry Mammon,â you tried to calm him with a soothing tone âWe do something together when we come back, okay? Iâll even bring souvenirs for everyone~â
âYou better,â Mammon huffed and pouted, cheeks dusting pink from your cute expression.Â
âDonât forget to wear the outfits I picked out for your trip!â The avatar of lust chimed in âAnd make lots of cute pictures!â
âWill do, Asmo.â
Satan huffed, growing agitated by the minute âWe should take our leaveâ
âSatan,â Lucifer stepped closer, signaling his brother to step aside for a private talk while you were being encircled by the other five âI entrust that you protect her from any harm. You know how careless she can get.â Satan mentally huffed, glaring at his brother âIâm very much capable. Sheâs safe with me,â Lucifer nodded, unaffected by the harsh tone. âGood, come back safelyâ
âDonât need to tell me thatâ
You left the House of Lamentation, each of you carrying a large suitcase, and headed over to the demon lord's castle, leaving a bunch of disappointed brothers behind.
On your way, you ran into Simeon and Luke who were on their way back to Purgatory Hall. They greeted you two; Luke gave you a tight hug as well. âSimeon told me youâre about to go to the past in the human world, is that true?â
âYep, we want to do some hands-on research. We wonât be gone for long, so please donât be worried about usâ
âIâm not worried,â Luke denied with a blush (he was). âOf course you donât have to be, Iâm with her as wellâ Satan chimed in with a smirk. Simeon chuckled âI must admit, I am a bit jealous. It sounds like quite the adventure. I canât wait to hear about your experience.â Luke let go of you âUh-huh. Me too! Simeon told me the 1800s are a bit dangerous, so please accept my blessing!âÂ
âI thought you werenât worried, Luke,â Simeon said with a chuckle. The childâs cheeks burn brightly âS-still. Just to be safe! Better safe than sorry, right?â
âThat is kind of you. I make sure to bring you a gift.âÂ
His eyes sparkled and his smile widened. Then he closed his eyes, muttering a blessing. A colorful light engulfed you and you felt suddenly very light and warm inside. Â
âStay safe you two!â
Barbatos greeted you near the entrance, standing proudly in the entrance area; looking fiendishly handsome like always.
âI was awaiting you, please follow meâ He led the two of you through the majestic golden Hall down to a familiar room. You went there back in your first year when you had to prevent Belphegor from killing you (You prefer not to think about it)
âDiavolo sends his best regards but he is currently buried in work and is unable to leave his officeâ You donât doubt it was thanks to Barbatos but didnât comment on it. âWe appreciate him thinking about us,â Satan stated and you nodded in agreement. âThank you again for my early birthday gift, youâre the bestâ The butler smiled with closed eyes âDonât forget the rare tea leaves for my payment. And try to not make too much of a messâ You feigned a gasp âI would never!âÂ
âAre you ready?â Barbatos opened a portal in a mirror.
Satan met your gaze, a soft smile on his lips as he grabbed your hand.
 âLetâs go!â
Alright, so what do we think?
