how would you describe ciel’s and sebastian’s relationship? like yes literally it’s contractor and the one who agrees to the contract. but like their day to day relationship with eachother. i dont ship them but i love how they interact with one another but don’t know how to characterize their relationship.

Dear Anon,

O!Ciel and Sebastian’s relationship is not something I could fit into any inter-human relationship categories. This is because theirs is simply something that seems very unlikely for humans to have in our society. However, that is exactly what makes this master-servant duo interesting.

Most clinically, O!Ciel and Sebastian are indeed master and servant, child and adult. Though surely very rare, child-employers with adult-employees might exist in our world. What makes O!Ciel and Sebastian’s relationship unique is by no means limited to this ‘subversion’ of child-adult dynamic. Let us unpack this master-servant bond category by category, layer by layer.

1. Child vs Adult – Age Dynamic

A unique characteristic of O!Ciel and Sebastian’s relationship is how they do not behave like any child vs adult would. Sebas treats O!Ciel like a child, but he does not see his master as a child. And by ‘child’, I mean more specifically ‘a less-than-adult’ person. To Sebastian who is centuries old, a human who is 13 is as inexperienced and foolish as a 30 or 60 year old human. Instead, it seems like Sebas treats O!Ciel like a child only because it gets on his master’s nerves and it is entertaining.

We must remember that humans are cattle to Sebas, and that O!Ciel is no exception. For analogy’s sake, let us imagine a pig. Humans usually don’t have a higher regard or respect for adult pigs than they have for piglets. We don’t take adult pigs more seriously than we do piglets.

2. Master vs Servant – Power Dynamic

The most unique part in O!Ciel and Sebas’ relationship is not that a child is the employer of an adult, omnipotent demon. The uniqueness is in the detail that this specific employer has absolute command over Sebastian, and can even use the demon’s powers against him at will. We see in the Werewolf Arc for example, how O!Ciel has practically already broken his end of the contract. Sebastian was in full right to claim his payment for his service and return home. But since the contract was technically not over yet, O!Ciel stopped the demon from exerting his right with just one simple phrase: “it’s an order.”

Sebastian may seem all-powerful, but if O!Ciel wishes to make Sebas do something against his will, O!Ciel merely needs to use the binding magical term “it’s an order”. This binding term is so powerful it can infringe all of Sebastian’s personal autonomy, and it would be ““legal””. What if Sebas doesn’t want to be touched? “It’s an order, let person X touch you and get away without harm.” What if Sebas doesn’t want to expose himself to lethal danger? “It’s an order, do it anyway.”

This is the reason why SebaCiel could never work (even if O!Ciel were an adult!), simply because the power balance is inherently tipped way too much to O!Ciel’s side. A romantic and/or sexual relationship cannot work as long as the power balance is off, and true consent cannot be given on all sides. Consent that can be coerced, or cannot be withdrawn freely, is not true consent, after all.

3. Master vs Servant - Bickering

There is a lot of back-and-forth bickering between O!Ciel and Sebastian, which is very uncharacteristic of employer-employee relationships (No way I’m going to bicker against my boss!) Sometimes the bickering is light-hearted and comical, and I surmise this is part of the reason people might have the illusion that their power-dynamic is not completely off (as described above).

This light-hearted bickering is a great appeal, and it makes the master not behave like a full master, and the servant not like a full servant. On surface their contract bears semblance to a friendly relationship wherein both parties also fulfil their respective roles in this employment. This is a powerful ingredient in their usually fantastic cooperation during their missions! O!Ciel allows Sebas some freedom (when he sees fit), while Sebas returns this ‘kind gesture’ with helpful initiatives (when he sees fit). I dare say that many if not most ‘Kuroshitsuji’ fans are here exactly for this reason. Regardless of how fantastic this cooperation might be however, at core their relationship is still ‘employment’.

On the darker side however, this bickering is also one of the fruits born from insidious manipulation. In this post I discussed how Sebastian stretches his arms and legs as WIDELY as possible within his tiny constraints. To a certain extent, O!Ciel turns a blind eye (pun not intended) to it. Why though?

Of course O!Ciel is not a complete tyrant towards Sebastian, but this is the result that Sebastian managed to fight and win for himself. All the way back in chapter 138 Sebas didn’t even know O!Ciel yet, and yet he already made very clear that:

In this small incident O!Ciel learned that if his demon misbehaves, he’d have himself to blame. THIS is the silent lesson Sebas instilled into the boy; that if Sebas mistreats O!Ciel, it is not Sebas who crossed boundaries, but that O!Ciel didn’t set the boundaries right. “O!Ciel had it coming”. This lesson taught by Sebas leans dangerously close to – if not downright within – the category of victim-blaming. (Sebas you trashy Trash Demon™, I love you.)

3.1. Circus Arc

So far in the manga, the most obvious example of this victim-blaming dynamic is the incident with the snakes in the Circus Arc. Sebas very clearly reminded O!Ciel that he is not above allowing his master to get hurt semi-mortally. O!Ciel was seething when he found out, and justly so. But did Sebas show any remorse? Of course not. Instead he blamed O!Ciel for:

3.2. Jack the Ripper Arc

Far more dramatically, this same victim-blaming dynamic can found in the Jack the Ripper Arc, and this one arguably even dictated how O!Ciel is going to become as a person.

In the Ripper Arc Sebas also obeyed O!Ciel’s order to the T. But that’s it; only to the T and nothing more. Because the demon deliberately withheld information from his master necessary for the investigation, more victims fell while the case was still in O!Ciel’s hands. Who gets the blame? Jack the Ripper obviously. But who is made to bear the guilt? O!Ciel is; through the victim-blaming Sebastian made him internalise.

O!Ciel is still O!Ciel, so he probably didn’t really lose any sleep over the deaths of 5 people. But had he not been him, then surely this guilt would have been mind-crippling. However, we need to bear in mind that O!Ciel was not unaffected; had Sebas not withheld information, then O!Ciel would have stopped the murders earlier, and presented a scapegoat to the Queen. Let’s be fair, had Madam been arrested then she’d still be awaiting capital punishment. But as the Watchdog, O!Ciel pulls some strings. He would have tried VERY hard not to lose his aunt too.

As it is however, the enormous guilt about the death of his own aunt is what Sebas made O!Ciel suffer through slow and insidious manipulation. Sebas never gave O!Ciel the time to mourn his aunt, and instead pressured the boy into admitting that he ‘callously sacrificed Madam as a pawn’. He made him mentally TAKE the blame for the murder that Grell committed, and Sebas could have helped prevent.

As we can see in chapter 13, O!Ciel was desperately trying to externalise the blame, coming up with excuse after excuse, justification after justification. None however, works. Good seasoning skills, Sebas, amazing food-prep.

I am fairly certain that O!Ciel doesn’t even realise how much he’s being emotionally manipulated by his butler throughout the years. This insight about emotional manipulation and psychological abuse is something that requires a level of abstract comprehension we cannot expect from most people, let alone a 13 year old child (however smart they may be.)

4. Conclusion

In conclusion, both Sebas and O!Ciel exist in this relationship rather amicably on surface level, but they are inherently toxic to each other. Sebas is continuously manipulating and emotionally abusing O!Ciel, while O!Ciel holds the absolute power to infringe all of Sebastian’s autonomy.

This ⇊ illustration by Yana is the perfect symbolisation of their bond.

We can attach adjectives like “f*cking toxic” and “fascinating” to this relationship, but we can’t find a category of inter-human relationship to fit O!Ciel and Sebastian into. In real life there are no children who can wield magical command to strip someone entirely of their autonomy. Likewise, there are very few adults who would not consider a child as ‘less-than-adult’. Should we try to shoe-horn O!Ciel and Sebas into a human category, then we risk over-simplifying this relationship. Over-simplification of this relationship can be very harmful, because the subverted formula of “child-master and adult-servant” SEEMS to compensate for the inherent power imbalance.

Yana however, managed to write this relationship SO brilliantly complex, that Sebas will always remain the servant who is at O!Ciel’s mercy, while O!Ciel suffers continuous mental abuse despite holding the ultimate ace card against a demon. This complex relationship is the ultimate evidence that even the most toxic relationships can look functional on surface level, and I love hating it!

I hope this helps give some insight!
