When our favorite butler and master duo get "captured" by a pair of hunters and an angel, they decide to play a dangerous game and get a free meal or two. (Spoilers, adopted from Resistant Raisin)

Black Butler x Supernatural Crossover

Crossover Kuroshitsuji/Supernatural (contain Sebaciel and Destiel pairings) Summary: It was only destiny that made them met this day and of course the will of the angel in trench coat to help people. Gabe is interested, Sebastian angry and Ciel more than a little shocked. Sorry for the bad summary...

When she almost dies in a fire that destroyed her family, and a priceless relic is stolen, Nicole Tryst makes one final gamble. Too bad the book wasn't exactly accurate about what would happen, and just why are there two handsome - if injury prone - men following her? Rated T to be safe Sorry about nonexistent line breaks in Chapter 3. -.-

A case that can't be solved. Two worlds colliding in the most confusing of ways. The infamous Phantomhive and his demonic butler meet the Winchesters on a case where a demon-run Carnival causes whole towns to empty in mere hours. Can they work together to save what few survivors remain? Or will Sam and Dean's hatred of demons keep them from trusting Sebastian, and ruin the case?

The Winchester boys bite off a bit more than they can chew. A foreign country, a demon on steroids, and Grell Sutcliff- how much can these guys take? One-shot, modern day Black Butler au.

Ciel Phantomhive made a contract with the demon Sebastian under strange circumstances...how does Sebstian's real boss, Crowley, feel about this? What problems does this rewritten contract cause in the future, and to what extent will Castiel and the Winchesters go to prevent that? (rated cuz idk what'll happen later, might keep writing)

Grelliam. After the Darkness walked free again, all supernatural creatures freaked out, even Gods…When Grim Reapers were being killed, a very special and flamboyant one came to the Winchester brothers demanding them to help.

When Sam and Dean summon two demons they didn't expect to be confronted with Two Victorian English ones, a scarlet reaper that doesn't even follow the same rules as regular reapers and a bratty Earl.

What happens when something from the past meets Ciel and his Butler that also peeks Sam and Dean's curiosity for a new case. BTW swearing, don't really have to have watched to certain season, just know who characters are and plot of the story.

Sebastian Michaelis and Ciel Phantomhive are now in the present era of 2009 living among the humans by Ciel's orders due to the fact the underworld was boring after being there for centuries. Sebastian finds on accident the Supernatural book series and now he and Ciel both question the lengths these "people" would go to be some fictional being.

After years of praying for Castiel to return her father back, Claire Novak gave up in praying and learned more about demons. One day she summon a demon names Sabastien Mikaelis and made a deal with him to help her gets revenge from an angle names Castiel who screwed up her life. Slightly AU with Destiel.

The kingdom of Croatian has been taken over by zombies and King Ciel is dead. You are their last hope. Drabble, medieval AU

Sebastian has been released from Ciel's contract, but only for a short period of time. He has to make the most of his freedom by finding the most delicious soul he can! Elizabeth has grown up a hunter, but realizes her own powerlessness when her whole family is taken. What is she willing to sacrifice to get them back? Black Butler/Supernatural Crossover, Sebastian/OC Enjoy!

What happens when a demon and an angel are roommates? Join our favorite demon, Sebastian, and our favorite angel Castiel as they argue their way through living.

After all that work to trap Crowley, the demon has a few extra tricks up his sleeve. He can get Sam's soul but the boys need to do something for him first. Bad Summery! plz read! SebbyxCiel DeanxCas maybe Enjoy!

What happens when an angel and a demon make a deal?

"While humans may go to Heaven or Hell, reapers had a much different fate." When the Thorns finally take Alan, he wakes up. But not in his bed.

"William T. Spears, Supervisor of the Shinigami Dispatch Association, was wide awake, just about to finish up his overtime. Despite being the cold hearted, emotionless creature he was, even he couldn't help but get terrible chills from storm outside." a.k.a. what happens when William gets too much of an ego. Not too thrilled with the ending, but I tried.

Writing this for a friend who had another friend suggest it. - -

Castiel has tracked Crowley down to a parallel past, where London is ruled by Queen Victoria, and her "watchdog," Ciel Phantomhive. He soon realizes that he's going to need the help of two specific hunters to deal with Crowley, and another supernatural being... Sebastian Michaelis, the butler of the Phantomhive Family.

An alternative happening between episode 16 and 17 of season V. Sam and Dean were dragged by Cass to another country and his lead of finding the colt, the demons he say should be able to tell them where it would be. Pairings: CastielxOCxClaude, OCxSebastian Characters: Claude, Morganne Brittany, Sebby, Ciel, The Winchestersa and most of all Cass.

While watching Supernatural one day, I was inspired. FIRST CROSSOVER! In the year 2012 Ciel and Sebastian are bored of life as demons. When crossing paths with the Winchester brothers, perhaps life will get a little more interesting as well as deadly. Kuroshitsuji 2 spoilers for those who haven't seen/read it. Rated T for swearing etc. AU
