Black Butler (manga)/WMG

Ciel's current goofy staff are ghosts.
We know that. It's possible they were all killed and Sebastian's keeping up their images to keep his contractee sane until he can fulfill his contract.
 * As per ep 7, we know that Finian was used for weird experiments. Possibly they aren't all ghosts, but they might all be weird, in different ways.

Grell is the bastard son of Suigetsu and Karin
I mean look at them. He gets his teeth, sense of humor, and his love of giant swords from his dad and his hair and his taste in "friends" from his mom. The resemblance is hard to deny even if you don't ship it.
 * MUWHAHAHAHAHA! I'm not the only one that thinks Grell bears a resemblance to Karin!
 * Wait, didn't Grell appeared earlier than either of them? Besides that, yeah that makes so much sense.

Ciel's current staff is/was his personal army
(note: I'm going from the manga) Ciel picked this Power Trio for their usefulness in combat but they haven't been needed because of Sebastian. With nothing else to do Ciel made them his house staff, much to his eternal regret.


 * Maid - Child soldier and expy of Roberta and Ms. Van Winkle.
 * That's First Lieutenant Van Winkle.
 * Cook - Guerrilla fighter/gun runner/demolition expert. (He wants to be the flambe chef from Ratatouille but he just can't.)
 * Gardener - Cute Bruiser due to experimentation (super soba with a side of gamma rays?)
 * The above three are confirmed.
 * Butler Tanaka - Very, very extended Heroic BSOD due to the fact that his dead master has returned as the butler combined with, just maybe...

Sebastian slaughtered Ciel's family
He wanted Ciel's sweet, delicious young soul (after a bit of "tenderizing"). One day Butler Tanaka's going to snap and go "It's HIM!!!" and attack Sebastian with his own pastry.
 * Alternate theory: Sebastian was summoned by the cultists, but he liked Ciel better.
 * The 'Alternate Thorey' is confirmed as of chapter 63. The main thorey, however, is jossed.
 * If that were the case he wouldn't have agreed to eat Ciel's soul only after he killed his parents' murderer would he? Catch 22

The Noah's Ark circus' performers prosthetic limbs
Are made of PEOPLE!!!
 * Confirmed as of Chapter 34.
 * Confirmed as of Chapter 34.

Sebastian is not in his real form.
He is actually assuming the shape of Ciel's father, as per his request.. I thought they looked uncannily similar.
 * ...Ciel's father was Alucard?!
 * The final episode confirms that Sebastian's usual butler form is not his true form.

Sebastian does not eat Ciel's soul.
Instead, he forces Ciel into becoming his Battle Butler, and they have even zanier adventures in Hell.
 * I have to tell myself this to stop myself from crying.
 * Maybe confirmed now that the anime is getting a second season.
 * Only about half-confirmed
 * I wonder which one Ciel would prefer, given the choice...

Ciel is (somehow) the lovechild of Count Cain and Lelouch.
Pretty self-explanatory.
 * Delilah does make a lot of dolls and dabble in some very bad hoodoo...

Sebastian, in his true form, is female.
Either that, or a crossdresser. All we know is that he wears a pair of dominatrix boots.
 * Sebastian's true form is HIM?!?!
 * It's not outside the scope of possibilities.
 * Whatever he is is Nightmare Fuel, judging from Ash's reaction and Sebastian's insistance that Ciel shield his eyes.
 * That's anime continuity, though. Sebastian had no problem with appearing in his true form in front of Ciel in the manga. Ciel didn't even seem too fazed by it.
 * Sebastian's true form is an Eldritch Abomination which drives people insane just by looking at it. What we saw was the closest thing a human could see without going crazy.

The Cultists were trying to summon Sebastian.
In the manga, if you look closely, his symbol is on the floor of the room where they were torturing Ciel. Maybe they were trying to summon him using the children's souls as payment instead of their own? Furthered by the fact that Ciel seemingly manages to summon him 'accidentally'... by renouncing God and calling for "someone, anyone" to come save him, "It doesn't matter who, it doesn't matter how". If the link was already open by the cultists' attempts, that seems much more likely to work.

Sebastian doesn't really have sex with either of the girls.
He just fingers them. Note how in both scenes Sebastian seems to be fully clothed and not moving very much, and after he comes back to Ciel in the manga he isn't wearing his gloves because "They got dirty".
 * Well, I guess that's somewhat better...
 * The inflagranti delicto scene in the manga IS rather ambiguous. However, both hands are accounted for (one gloved, one not -- he'd removed one already because it had gotten bloody from the preceding confrontation with Spears), suggesting either he wasn't using them OR there was some creative position-switching occurring between frames. It's likely left unclear on purpose to allow the reader to insert his or her own interpretation... which I'm sure many of us have done with gusto. But there is something delicious about the implication that Sebastian is so efficient, even during sex, that he doesn't need to disrobe.
 * Fangirls would like to think that he just fingered them. His scene with Beast is rather ambiguous, but it's pretty obvious that he at least had sex with the nun. Also, all over Kuro fandom, Sebastian always has sex fully clothed. I'm pretty sure that it's canon that he doesn't like being naked around humans, so there's that, too.

Sebastian in his true form is... Uryu Ishida.
They do look similar. A lot, if you ask me. The events in Black Butler happen after Bleach, and Ishida could have become Sebastian in an arc we have yet to see. And since he's a powerful demon of sorts, he doesn't need his glasses anymore. Also, it'd be hilarious to see Ishida as a Memetic Sex God. Not that he isn't really near of one in the original series, though. He just needed to lose his awkwardness, which happened majestically. Also, he changed his name so Ichigo and the others won't mess up with his current mission/forms. He'd be at disadvantage if they decide to "cure" him.

If you still doubt that, compare them.

...Alternatively, Rokudo Mukuro is one of his reincarnation (or getting possessed by Sebestian).
They look extremely similar, have the same suave attitude and have supernatural powers. Plus, their closest partner both wear eyepatches signifying the bond between them.

is not dead.
While this is probably not very wild, by looking at what happened in the newest chapter we have Sebastian giving Ciel his 'comfort pillow.' My guess is that this is BS and really Sebastian slipped a note in said pillow, outlining the plan of the 'fake death.' Finny was ordered to clean out all the fireplaces; Ciel probably burned said note- that chain is pretty long so it's possible- and Finny unwittingly disposed of the evidence. Ciel was awake before Arthur, giving him plenty of time to do this. My guess is that the servants are not in on this plan and their reactions are genuine. Ciel, however, is acting albeit extremely convincingly. During his seeming hysterical fit, he manages to pull something off of Sebastian's clothing, which will help Ciel determine the identity of the true murderer or confirm his suspicions. It also is likely to be whatever was found in the fireplace.
 * Somewhat confirmed with chapter 47.
 * Completely comfirmed in Chapter 50
 * Okay, come on. Did anyone actually believe that? He can freaking tank barrage of bullets, why would a simple stab to the back kill him?!

The killer in the mansion is a shinigami, likely Grell.
Therefore making the 'needle and string' theory unnecessary. In earlier chapters, William and newcomer Ronald mention that Grell is somewhere on the premises... What if he NEVER LEFT and is hiding out somewhere in the mansion?
 * Supported by the fact that the killer does seem to holding a weapon that looks a lot like a scythe
 * Jossed. That wasn't the murder, it was just Bard.
 * Jossed again. Everything is explained in chapters 48 and 49. Besides, Grell was probably there for actual Reaper duties. Who knows what kind of punishment he went through after the Jack the Ripper arc.

Combining the above two theories...
'death' is an attempt to make SO DAMN UPSET that he comes out of hiding, either in front of everyone, where he would be revealed as an obvious suspect or alone, where Sebastian could incapacitate him without breaking character. He is pretending to be  after all.

Ciel planned the murders
For unknown reasons, Ciel planned a string of murders with Sebastian as his accomplice. Ciel invited Arthur Conan Doyle to the party so that there would be someone smart enough to "solve" the case based on the subtle hints arranged by Ciel, confident that Arthur wouldn't discover the real truth since he wouldn't know that Sebastian was a demon and what he was capable of.

Ciel shot von Siemens and then did the trick with the thread and needle, which he had practiced earlier. He told how he did it to Arthur since Arthur would be intelligent enough to be suspicious of what would have been such apparent stupidity had Ciel been the murderer. Ciel also made a point to act like a nice child around Arthur in order to evoke his sympathies.

Sebastian brought Ciel a means of opening the lock of the chain inside the pillow. Ciel faked sleep until Arthur was soundly asleep and then opened the chain and slipped out to "murder" Sebastian. With Sebastian playing dead on Ciel's previous orders, the both of them now had good alibis: Sebastian due to supposedly being dead and Ciel due to having been under guard. Moreover, Sebastian was now free to move about stealthily and murder additional people without himself or his master being suspected.

It's possible that Sebastian even made the weather to suit the plan.


 * Partially true. It seems he knew the murders were going to happen but he let them happen in order to expose a few of the guests. It's also explained above

Sebastian is Ciel's grandfather
Ciel's father Vincent looks suspiciously like Sebastian, but the reason for that is not that Sebastian based his current appearance on him but that Vincent is Sebastian's son. The Phantomhive family's reputation for evil goes back for generations, and Sebastian was the demon they dealt with. During this time Sebastian became an expert in the ways of English noble households and learned to cook all of those fancy dishes while remaining ignorant of things like curry. Sebastian took different shapes during the years. He served as Vincent's familiar in the form of a black dog.

Sebastian is Malphas from the real demonology
I saw this basic Sebastian = Malphas suggestion elsewhere on the Internet; here is a version with more detail. I shall compare text from the rather terse article from The Other Wiki with how Sebastian has appeared in Black Butler.

He builds houses, high towers and strongholds, - Sebastian has shown the power to restore the Phantomhive manor when it gets wholly or partially destroyed. This is especially apparent as supernatural in the manga chapter 37.

throws down the buildings of the enemies, - The end of the Circus Arc shows him doing that.

can destroy the enemies' desires or thoughts (and/or make them known to the conjurer) and all what they have done, - This one doesn't have much in the way of solid proof, but Sebastian has shown insight into human behavior. However, Sebastian could be based on the Pseudomonarchia Daemonum description of Malphas which differs here from Ars Goetia.

gives good familiars, - Or rather, is a good familiar.

and can bring quickly artificers together from all places of the world. - If you expand the definition of artificers to include all manner of experts, the servants qualify here.

Malphas accepts willingly and kindly any sacrifice offered to him, but then he will deceive the conjurer. - Perhaps this was what happened with the black magic ceremony that led to Ciel getting the contract.

He is depicted as a crow that after a while or under request changes shape into a man, - The beginning of episode 1 of the anime shows this very thing.

and speaks with a hoarse voice. - The black speech bubbles in the manga suggest a voice different from his human one, but his voice in the anime isn't really that hoarse.

Overall, I'd say that's a pretty good fit.


 * I agree with this interpretation. My first impression when watching the Anime was that Sebastian was more than just a regular demon. He is obviously a high ranking one, perhaps at Duke or Prince level (from demonology). The entry for Malphas says that not only does he take a crow/hybrid man-crow form when summoned but that he is a high ranking demon of hell, a "great president" or prince. Also, there is
 * The ghosts from the Tower of London in the anime did say that he looked like a crow in his tailcoat.

Alois from Season 2 of the anime is on the side of Heaven
Claude Faustus the chartreuse-eyed butler is a shinigami with the most misleading name ever. Hannah the super-blonde, violet-eyed maid is an angel. Alois himself is a key player in some plan to "purify" the world, possibly even being the Antichrist. They will be the main adversaries of Ciel and Sebastian in Season 2.
 * It's unlikely that Hannah is an angel, what with
 * We'll see if Hannah's ... In any case, remember Angela the angel maid from the first season. The similarities are clear.
 * It's also noteworthy that the Tarot card Alois holds in the Eyecatch is Judgement. The card shown has a cross and an angel blowing a trumpet in it. It refers to the Christian Last Judgement.

Or, Faustus and Alois are related to The Fair Folk
In episode 1, we had Alois referred to as a "changeling" (at least in the English subs) and his trickster-like behaviour is similar to how traditional fairies are depicted. The fact that the contract involved a spider also seem more attuned to nature than either heaven or hell. Plus, Faustus is a great tap dancer - what more evidence do we need?

Grell is the 13th guest
Oh come on. We all want him back.
 * Yeah...didn't see that coming either.

The killer from the recent arc is Beatrice.
The recent arc is starting to play out a lot like the first game in particular, though like the following games as well- Sebastian being a demon, who knows, there could be some sort of connection between them. Plus Beatrice would have absolutely no trouble committing those murders, being a witch and all. Basically, Beatrice is trolling him out of boredom. Works particularly well with the above theory that he is originally Malphas, which means he may be one of the 72 demons mentioned in Umineko (similarly to Gaap and Zepar and Furfur).

A snake is used as a weapon in the recent murder mystery arc.
Because since they are parodying Sherlock Holmes, they might as well run with it. ...Actually, might as well say the whole arc is a condensed version of A LOT of Sherlock Holmes stories.

Jeremy is really
Considering Jeremy's extensive knowledge about dead bodies, criminology, the Phantomhive estate, and cooking, it's not that far out there to think that  may have just switched bodies since we all know he can't be killed for real due to Plot Armor. Maybe he switched bodies on purpose under Ciel's orders in case they actually did murder the guests or maybe the killer got the upper hand and he didn't want to resurrect himself in front of them so he was forced to come back as another person. In addition, in Chapter 45 Finny says he has the odd feeling that he can trust Jeremy. There's also Jeremy's creepy smile and impeccable manners that are far too similar to  to be a coincidence. Although this troper will be very upset if her theory is true and we will no longer get to stare at  gorgeous former body.
 * Plus Jeremy had
 * Plus Jeremy had

Sebastian and Claude are Non-Identical Twins
Self-explanatory, really.
 * I believe the term you want is "fraternal twins".

Series 2 Sebastian got his new arm from Noah's Arc Circus
He lost an arm in the final episode of the first series, remember? So unless it grew back, this is the only way he could have obtained such an advanced prosthetic.

Series 2 Sebastian made a deal with Undertaker
...to bring back, who had clearly been offed in the first season, before bringing back around. He then modified memory to remove the more traumatic events of the past season, which would explain why he has no memory of  and thinks Madame Red is still alive, when it is hinted by Sebastian that she, in fact, stayed dead.

Sebastian has been poisoning Ciel's tea
The story puts a lot of emphasis on Sebastian serving tea to Ciel. What if that's actually plot relevant? In the anime Sebastian has shown the ability to make supernatural kind curry, and several things that have first appeared in the anime have later appeared in some form in the manga, such as the backstories of the servants, suggesting that the makers of the anime have had access to spoilery information. My theory is that Sebastian has been using his culinary demon powers to make Ciel's tea suffused with evil. That tea has been gradually poisoning Ciel's soul throughout the manga and is in large part responsible for the direction of Ciel's character development. In the manga Ciel is not aware that Sebastian can do that kind of thing, which is why Ciel has given no orders to forbid it.

Alois's sense of taste is screwed up.
Ciel's magic-demon-pentagram eye screws up his vision. Alois's demon-summoning symbol is on his tongue. Therefore it only follows that Alois's sense of taste would be off. Everything Alois eats tastes like crap, and this is why he is such an evil prick.
 * ...Awesome

Alois wasn't abused by his father in the first scene
Naked and bruised Alois in bed with his father wasn't anything like it might seem. Firstly, I think Alois was so thoroughly messed up that he tried to seduce and manipulate his father by appealing to his sense of sympathy just like he would later accuse Hannah of doing. It didn't work, because his father wasn't a pedophile. Secondly, Alois's father wasn't his biological father at all. The hair color of the abducted baby doesn't fit Alois. My guess is that the old Lord Trancy found himself a son not for any sleazy purpose but simply because he knew his younger brother would bring dishonor to the title and bring the estate to ruin.
 * As of Episode 8, this theory is

Claude is only pretending to be a demon
Claude is not really demon. It's just an act. He gives himself glowy eyes and fangs with the same supernatural method he used to redecorate the Trancy manor dining hall in the first episode. (Fairy glamour? Although he might not be a fairy either, but for example a shinigami...) Claude's long-term plan has something to do with Ciel, and Claude needs to manipulate and deceive Sebastian to ensure that the plan stays on track. As for Sebastian, he is likely not fooled at all, but as a sneaky demon is hiding that fact from Claude.

I think it's noteworthy that Claude has a spider form while in the story of the Spider's Thread, which gets referenced several times in Black Butler, the spider is a saint who interferes to save a damned soul from Hell.
 * To be exact, Claude is William T. Spears in disguise, which is how he knows Sebastian under his current name that was given by Ciel. William put on different glasses, changed his hair from neat to messed, and spoke with as deep a voice as he could manage in order to appear as a different person. From Grell we know that it's possible for a shinigami to work as a butler while still doing his shinigami job. Also, perhaps demons and shinigami are fundamentally the same species, which would explain why their combat and other capabilities are comparable, allowing them to make plausible impressions of each other. The difference would be that demons have gotten to the taste of eating souls, which is very much against the shinigami rules.
 * As of Episode 8, this theory is

Alois Trancy is Count Waltz in another universe.
Look into your heart. You know it to be true.

Hannah made a contract with ...
To keep Alois safe and alive. Which is part of the reason why she went against in episode 8, and fought   to keep him safe. She could've easily left him there, as he was  anyway.

is going to come back to life. Somehow. If  could die and come back in the anime, it's not much of a stretch that   could come back too. Especially as both  appear under them in their blood as they were dying/dead, and both of them had their rings stolen (both of which are implied to contain their souls), it's possible that   could come back, albeit in a pretty messed-up body.
 * Semi-confirmed as of episode 10.  is back,.

Hannah worked for the previous Trancy earl before his death as well as Alois.
Think about it. She has the same uniform as the maids in Alois' flashbacks in episode 8, and she would have known about the earl abusing all those boys and done nothing about it, explaining why Alois' hates her so much, even in comparison to other demons (for example the triplets.)

The entire second season of the anime is secretly promoting PS Company (a visual kei label).
The Gazette does the opening theme, and the whole spider/tongue thing ties in with a pun in an old alice nine. song. If you try really hard, it's possible to interpret the entire storyline as an expansion of the song.

Finny is the real heir to Trancy
Blond hair, blue eyes and probably kidnapped at a young age... Hmmmm...

Alois is the alternate of Oz from Pandora Hearts
What do you meanthat's not Alois?
 * Though he does have a lot of similarities to Vincent as well.
 * No no no, When Vincent gets his well-deserved death, he gets to become a reaper - Grell, naturally.
 * Oh, yeah. That makes sense. And is Undertaker Break after he became a Goth?
 * Lizzy's brother looks a lot like Elliot.
 * Ooh! Ooh! I only just thought of this! Does Philippe grow up to be Ciel?
 * I'd say Phillippe looks more like Luca, Alois' younger brother. Alois looks out for Luca and Oz looks out for Phillippe.

Snake will turn out to be as 'incompetent' as the other three.
It's Black Butler, what do you expect?

Claudia P. is related to Ciel. A Phantomhive
Remember that pendent that Undertaker had at the end of the Circus Arc? The name Claudia P was scribbled on it. My guess is Undertaker might be a demon too, hence the black nails. He's destined to never be human, like the anime. Claudia Phantomhive might have been one of his contractors. Heck, Claude from the anime might have been named after her, for teh lulz or to show that the manga name might have importance....

Ciel
Which is why Sebastian never had to send her a farewell card, why Ciel's not so hungry-acting, and why his eyes flashed red at her while they're dancing. Know it in your heart to be true that Mary Sues will always die.
 * Except that she 'did' receive a package and went to tears over it. Also, Lizzie is flawed, not the focus of the story at all, and not everyone likes her. Mary-Sue? Doubt it.
 * OP: No she didn't. We only saw Sebastian give out packages to Undertaker, Lau, and Soma + Agni. Plus, Mary Sue isn't defined by everybody liking a person. Though, I did leave it as a YMMV. You may not think she's a Sue, but there are people in the Black Butler community do. It's all based on matter of opinion.
 * She's mostly thought of as a sue because everyone wants her to Die for their ship. If anything, Sebastian is probably closer to Mary Sue/Gary Stu.
 * Yes, actually we did see her receive her "package". The others received a gift from Ciel, delivered by Sebastian. Lizzie's gift is the dance with Ciel, something she's always been pestering him about. Also, it is unlikely that he  since   to do so, right?
 * Actually, a contract is not required. Waaaay back during the ripper arc William ans Sebastian have a talk that basically implies Sebastian is a 'classy' demon. In other words, a contract isn't required, but is sometimes offered.
 * By the way, Lizzie's personality is the opposite of Ciel's (cheerful, definitely not vengeful...)
 * Quite honestly this WMG seems more like a bad fanfic than an actual theory. Ciel would never have eaten Lizzie, the White Stag episode shows that they're either close friends or actually in love.

Ciel is the alternate-universe version of Batman.
Both run their own companies and are the children of wealthy families. They are both pessimistic cynics, very intelligent, fond of dark colours and sometimes have to mask their true natures. They wage war on the criminal underworld, driven by. And has anyone else noticed that Tanaka and Alfred look awfully alike? The manga even has a character named Joker, who happens to be a circus performer! So either Bruce Wayne is the reincarnation of Ciel Phantomhive or the both come from alternate dimensions.

The Noah's Ark Circus is Coming Back
The mangaka could have killed him off arbitrarily, but didn't. Instead, he was spared and put to work as a footman with the promise that they would find the rest of the circus. There's no other reason to keep Snake alive unless he's going to sacrifice himself during this chapter or he's going to find his buddies in the circus and they'll ALL work for Ciel.

Lizzy knows everything
She's just pretending to be oblivious because she doesn't want Ciel to feel guilty.

Ciel isn't the real Ciel Phantomhive.
He just another kid that looks a lot like him, or somehow he was able to transfer his looks to another body after being sacrificed by the cultists. Would explain how in chapter 54, he can't seem to tell whether he was in the cage, or dying on the sacrificial altar. Or alternatively....

Ciel has an identical twin.
And they had some memory melding like process and can't tell whose memory is whose anymore.

Ran-Mao is a demon.
When the story Lau tells Ran-Mao is true and he actually is that Zhou he is talking about, then it could be possible that like Ciel he had sold his soul to a devil, just with the twist that he could get a little (super-strong)sister that would do anything for him and follow him everywhere he goes.
 * Sister? You DO realize Lau means something else, right?
 * It would explain her fighting skills. And those cat ear shaped odango could be hiding demon horns.

The whole season 2 is
The way everyone looks like Wish Fulfillment.

Kazuki from Glamorous Lip is Ciel
They look and act very, very similar sometimes. If you disregard the whole yaoi thing. Considering that both series are written by Yana Toboso... Maybe when Kou-chan that was 's way of making a contract.

Sebastian's true form is that of Dr. Frank-N-Furter
That or Catwoman.

Ciel and his staff are 19th century Shadowrunners
Ciel is a noble who secretly works for the Queen clearing out the worst of London’s society (usually under the cover of night). He is a Face, the one who speaks for the group and accepts jobs from the Johnson (the Queen, usually). His day job (negative quality) is running the company, being an earl and doing noble things. When he gets a job, he rallies Sebastian - while classified as a demon, is a force (insert obscene number here) spirit summoned by Ciel under dire circumstances and is thus bound to him (Ciel must have drained something fierce to not have instantly killed himself). They go, they do their job (usually standard Shadowrunner fare - missing children, drugs, information) and they get paid handsomely. While Ciel and Sebastian are generally the only ones needed for a mission, the others are there if needed, and if they need help defending the manor (their ‘haven’ as it is). Ciel has a vast network of contacts as well, from Lau (drug merchant) to Undertaker (former Shinigami), I would assume most of them are high Loyalty/Connection ratings (especially Undertaker). His success in missions has lead to the Queen relying on him and no other groups throughout his services.
 * Ciel is a Face. He is competent in combat, but why should he ever have to show his skills when he has such a crew around him?
 * Sebastian is a summoned spirit, force is unknown. How many services he owes Ciel is unknown, as the first was to save him, the second was to serve him as his butler, and several orders are given throughout the series. The contract mark in his eye is actually to show that Sebastian is bound to him, and the act of
 * By rights, Claude would fall under much the same rules as Sebastian. However, he does not enjoy Alois’ presence, and enjoys draining his essence and magic at every turn.
 * Finny, though naive, is a physical adept who cannot quite control his strength. It is simple, and rather obvious. His super strength may have been natural, and the Obviously, he is aware of his adept powers, though perhaps not entirely how to use them properly.
 * Meyrin, obviously, is a gunslinger adept. It shows in her marksmanship, and were it a proper Shadowrun world, her eyes would quite obviously be augmented somehow (possibly cyber eyes), but at present, her powers all go into Hawkeye and Longarms Proficiency. This makes her rather inept when it comes to other sorts of tasks, as her build is not meant for anything but shooting.
 * Bard is simple - a street samurai with specializations in explosives and improvised weapons. Everything can become a weapon to him, and he will make it something powerful and useful, even if it is only short-term.
 * Bard is simple - a street samurai with specializations in explosives and improvised weapons. Everything can become a weapon to him, and he will make it something powerful and useful, even if it is only short-term.
 * It is entirely possible that his family were rather renown runners, and that he was well aware of his parents’ (yes, plural) work in his youth. Vincent was also a Face, and Takana, while not a summoned spirit, definitely qualifies as a physical adept. While I have no doubt that the job of a Shadowrunner could be kept from a spouse, I do not believe that Rachel did not know of her husband’s work, and perhaps had her own contacts that she could use to gather information for him on his jobs.
 * This, of course, brings me to Lizzy.
 * And what about the Shinigami?
 * Anyone who knows Shadowrun would be well aware that there are megacorps, giant corporations that in some places rule entire countries, and are capable of waging massive wars against one another. Sure, sometimes they hire shadowrunners, but mostly they loathe and despise them. They are the ones keeping tabs on the runners, ensuring that they are not getting out of line, and when their paths cross, more often than not - someone gets pretty dead (look at ). If someone needs to be getting dead, they’re right there to do it, and fuck if anyone gets caught in the crossfire.

The Black Heart is piloted by Grell and Sebastian.
The Black Heart is black with red trim. Sebastian is the titular butler in black. Hearts are red. And Grell loves her red.

Soma Asman Kadar had an ancestor or relative who died and became Yoruichi Shihouin.
They both are rich kids with purple hair, golden eyes, a somewhat excentric yet nice personality and a very special relationship with their bodyguard.

In episode 17, Sebastian had
That's one of the reasons why he

Trauma, and not any of the things that most real-life Western churches consider "unclean", are the only things that the purification church in the anime considers an impurity.
Mathilda smelled like a demon because she had demon on her, both metaphorically and literally. She was still pretty "pure" or would have been if it and her boss's reaction wasn't traumatic. It's kind of like them getting the Fruit of the Tree of Knowledge of Good and Evil pumped from their stomach, only in this case it's the Fruit of the Tree of Knowledge of Life's Suckiness.

Every time Ciel says, "Sebastian, this is an order," he owes Sebastian a little bit more.
He does tend to restrict that phrase to important times.

Ciel told Sebastian to treat most of his orders as requests in order to keep Sebastian from having as many opportunities to be a Jerkass Genie.
"Sebastian, this is an order" means "Now, exactly as I say". They have a standing deal that any other orders he gives are to be treated as requests from a boss, and for Sebastian to take his time and use common sense to try to interpret them as Ciel most likely means rather than as might benefit Sebastian the most.

Sebastian wasn't always a demon.
Why Not? It's possible that he  Another possibility is that he was (most likely unwillingly) turned into a demon by another cult. His Extreme loyalty to Ciel could be a parallel to a strong devotion he had to someone while he was human and/or the last empty remnants of his personality after a horrifying dose of Break the Cutie. As for the reference to the black death, he has either been a demon for hundreds of years (This would explain his Antiquated Linguistics) or is straight up lying. Demons aren't the most honest creatures in the world. I'm rather new to the series, so let me know if this is Jossed already, and please don't get angry if it is! >__<
 * Not completely Jossed. However, Sebastian and demons in general do not lie, and the reference to the black death wasn't in the manga. Furthermore, his devotion to Ciel isn't exactly 'extreme' per se and he has no qualms about endangering Ciel. This is only in the manga though, so your theory may or may not be correct in the anime!verse.

Elizabeth is going to find out that Sebastian is after Ciel's soul and then she'll try to fight him.
We can all see where that's going to go...

Shinigami can see in more dimensions than humans.
Cinematic records are only visible in a dimension that humans are generally unable to see. Shinigami eyes are configured to be able to see this additional dimension, but it throws off their sight in regular dimensions. Hence the reason all shinigami are nearsighted. Their glasses are constructed in such a way that they correct vision problems without making the shinigami unable to see the extra dimension.
 * Not that you don't have a point, but the only Shinigami to be seen with horrid vision is William, and that was just in the anime. Ronald's reaction didn't seem to be one of that who truly knew the importance of reaper glasses. Still though, everything else is plausible and makes a lot of sense.
 * as of chapter 61 there seems to be some truth to this. At least the nearsighted part was confirmed although if they are aware of more "dimensions" or something like it, it's probably not through sight as.

Grell Sutcliff is related to Death the Kid from Soul Eater
Think about it. Death the Kid is a grim reaper. Grell is a grim reaper. Kid is trying to turn his weapons into death scythes. Grell already has a death scythe. Coincidence? I think not!
 * That applies to both characters' entire species. This could just as easily apply to Ronald, William, or.

Sebastian's actual demon form in the manga is female.
All the hints of of Sebastian's demonic appearance seem to be leading up to more of a Fashion Victim Villain than an Eldritch Abomination (seriously, heels, what might be mascara, and Femme Fatalons?) but is actually playing on the assumption of the readers who have gotten used to all the Ho Yay that gender means anything to Sebastian; unlike Grelle, who's transsexual and actually is mentally female, Sebastian elected to Gender Bender herself a) For the Lulz (guys still want her even as a man, something that amuses her to no end, and now women are swooning over her) and b) Ceil saw what she used to look like and seeing her in a male form possibly modeled after his father is meant to make him uncomfortable; Sebastian's not going to be a servant for god knows how long without SOMETHING to make that less pleasant for the one giving orders, after all.

Sebastian hates being naked (especially in front of humans) because his true form has built-in clothing.
We see that it has something resembling stiletto winklepickers when he transforms in the anime. Perhaps he feels that humans are naturally vulnerable as well as weak, using clothes as prosthetic scales/feathers/whatever in the way that a hermit crab finds a shell, and that he feels less like a naked human and more like a plucked bird when stripped of clothing in his human form.

Sebastian's true form is an Eldritch Abomination with Alien Geometries, a Brown Note for Man, who was not meant to know such things.
We only saw flashes of his intermediate stages of transformation in the anime, not bits of the final structure. The feathers are not a direct result of his transformation, but a screen he creates so that the people of London don't get an eyeful of madness if they happen to look up at the wrong time and have particularly good eyesight. Ciel was close enough (both spatially and socially) that Sebastian didn't want to risk him seeing at all, and thus told him to close his eyes.

Sebastian is The Guide, Mk. 2.
With all the raven symbolism, the interpretation that he is meant to be Malphas (a black bird...thing), and the guess directly above (that Sebastian's true form is an Eldritch Abomination with Alien Geometries), this is the logical conclusion.

The killer of Ciel's parents...
Is the Viscount of Druitt. Why? Because he just won't go away, he seems to have really shady connections to damn near everything (selling unsuspecting women into slavery, naming himself ...) and this manga has a habit of turning its Joke Characters into Lethal Joke Characters. And you don't get more "Joke" than the Viscount.

The Undertaker loved a human woman who lied to him.
Manga continuity. She was either in a deeply committed relationship with him or they were actually married, if shinigami can marry humans. She possibly betrayed and/or left him, but he never stopped loving her. Eventually she died, whether by natural causes or as a consequence of the betrayal--it's possible that he even killed her, given his. This is why he says that the dead are more beautiful because they can lie no longer, like the living always do--because he was lied to before, and found his lover the liar to be more beautiful after her death. It also accounts for the  It's quite possible that this grief and love had to do with him giving up life as a shinigami to work as an undertaker instead. He probably kept her body and "played" with it. (Ew.)
 * Support. For extra WMG, the woman who died/he possibly killed was Rachel, Ciel's mother.

Grell will finally get that sex-change operation that she's apparently always wanted.
Sebastian will be squicked. Or maybe he'll like it. Who even knows with this series sometimes.

In episode 17, even if just momentarily, Sebastian was aware of the Fourth Wall.
And when he slammed his hand against the wall, he was really trying create a loud enough noise to get your attention and warn you that you should probably not watch this next part if your mom is anywhere in the immediate area.

The "Ciel" we are seeing is not the real Ciel Phantomhive.
When the real Ciel was in captivity, he befriended another prisoner who looked almost exactly like him, a la The Prince and The Pauper. The real Ciel was killed by the cultists, and his doppelganger took his place as Ciel Phantomhive. We see "Ciel" get quite brutally stabbed on the altar in several flashbacks (at the time that the contract is made, the real Ciel looks like this, and the text even says "Ciel isn't here anymore."), but the Ciel who contracts with Sebastian is not wounded in any way, and even if it had been long enough for the wound to have healed 'and' the wound was survivable in the first place, there's no sign of blood. Not to mention when the contract scene is taking place there's a bloody hand on the altar still. And in  recreation of the scene, there's the dead "Ciel" on the altar, and another boy in the cage who looks just like him. When introducing himself to Sebastian, "Ciel" hesitates before referring to himself as the Earl of Phantomhive. Sebastian even seems quite amused that this is what his new master is calling himself, though that may just be because of "Ciel"'s age. "Ciel" has no knowledge of things that a young nobleman would have already begun to learn, which is why Sebastian has to start tutoring him from scratch. "Ciel" also seems to have a very impersonal connection to his family after his return, as though he knows who they are and knows who they are meant to be to him but lacks the familiar love of a whole childhood spent with them (he even exclusively refers to Vincent as his "predecessor", not his father). He warms up to Lizzie and Madam Red as time goes on, because they show him love and he begins to love them back. Though "Ciel" has the goal of avenging Vincent and Rachel, perhaps he's doing it to avenge his dead friend and put his spirit to rest.

In conjunction with the above, the Ciel we are following in the series is biologically female.
This is rather more on the "Wild" side of Wild Mass Guessing, however, This Troper's guess stands. Whether he truly identifies as male or is living as male in order to take the real Ciel Phantomhive's place, as mentioned above (it's highly unlikely that this theory holds water if the Ciel we're seeing is the real Ciel, because it's Victorian England, and he's engaged to a girl he's known since birth.) there are a handful of signs suggesting this- and it's even lampshaded a few times. Ciel is very feminine in appearance (as proven by how exceptionally well he passed in drag) and he's been getting progressively more feminine as the series has gone on.(Contrast this picture to this one.) Beginning to go through puberty, perhaps? In chapter 37, Nina Hopkins comments that his measurements have stayed the same, with the exception of his waist being slimmer, implying he's getting somewhat of an hourglass figure. Frances comments that he's built more like a girl. And this is, perhaps, slight nitpick, but in Noah's Ark Circus, considering the backgrounds of most of the performers, he seems resistant to removing his clothes in front of other males beyond what one would expect for just the brand on his back. And even when he knows that Freckles is able to lift up his shirt at the back and see the brand, he determinedly holds his shirt down over his chest. Sebastian would obviously be aware of this (and most likely Tanaka as well, though Tanaka most likely knows EVERYTHING) as he's the one who dresses and bathes Ciel, but he would have undoubtedly been ordered not to breathe a word of it to anyone immediately. Just putting the W back in WMG, don't mind me.

Ciel's contract with Sebastian feeds off his energy
It's the only explanation I can think of for how someone that spends most of his days sitting around or being carried by his butler -- while eating a diet predominantly made up of sweets and cakes -- can stay so skinny. It may also have something to do with why his asthma suddenly came back after years of health.

Yana Toboso is a Bleach fan.
Compare Prince Soma with Yoruichi, Undertaker with Urahara, and William with Uryu Ishida. Also William and Ishida have the same Japanese voice, Noriaki Sugiyama.

William was once in love with a human woman who died.
This is based off of the "Shinigami OVA." Since the Toboso has been known to utilize plot devices from the anime, this doesn't at all seem farfetched. My theory is that William fell in love with a human woman who died, but he somehow got her to be reincarnated...only to have her completely forget about him in return. It's the reason he's so stoic and cold, and why he tells Ronald that "bringing your emotions into your job is a waste of time." The entire ordeal left him rather emotionless and bothered. Bonus points if the reason he hates being called "Will" is because the woman he once loved used to call him that.
 * Alternatively: The woman he loved had her soul devoured by a demon. Since we don't know exactly how reapers are created in the Kuroverse, it could very well be that William was once a human, and then he "died" and somehow became a reaper. Since he became unable to see that woman again, she thought he had died for real and in despair, summoned a demon to bring him back to life. But then the demon was like "nah I tricked you I just wanted noms," and that's why William hates demons so much more than the other reapers seem to.

Ciel, Batman, and Barnaby are alternate dimension versions of eachother.
Think about it. A rich kid see's his parents killed. He then becomes obsessed with avenging them. All three of them are the same.

Mei-Rin's likes wearing her glasses because they impair her vision.
In the beginning of her backstory, there's a man that says that her eyes are special and that she was born to be an assassin. Maybe she loves wearing her glasses so much because they keep her from seeing everything as a target, and that's why she only removes them when she's shooting. Even if they do make her a clutz, she won't take them off because she'd run the risk of killing everyone.

Doll survives.
And then she kills everyone. Including Ciel, that heartless son of a bitch. The end.
