Black Butler fans often ask the question "How old is Sebastian?" not only because of the character's immense popularity in the franchise, but also due to that being a very compelling mystery. The truth is that the author of the series, Yana Toboso, has never given a proper confirmation of this demon's age in the story.

There has been a lot of speculation surrounding the character's age in Black Butler, especially because he seems wise beyond his years throughout the story. Moreover, some hints in the series suggest that he is older than what people initially thought, which adds to the allure and mystery of the character.

Explaining Sebastian's age in Black Butler

As mentioned earlier, there is no concrete information in the series regarding Sebastian's age or even a general suggestion. It has been speculated by the fandom that he could be between 160 and 660 years old, although that is mostly due to his status as an adult demon, but once again, the manga and the anime never give a proper confirmation.

There were scenes in the series that featured Sebastian talking of old Egyptian Pharaohs as if he had met them in real life, which could suggest that he is at least one thousand years old. However, Yana Toboso, the author of the series, has never given any confirmation on how old the character is, which has led to a lot of speculation.

From a perspective of looks, Sebastian looks like an adult man in his mid-30s, which is a direct contrast to Ciel Phantomhive, the protagonist, thus making his dynamic work even better from an aesthetic perspective. However, the manga never makes things quite clear regarding his age, although that could be the intention.

More details about Sebastian

When it comes to Sebastian's role in Black Butler, he struck a deal as a demon with the protagonist, Ciel Phantomhive, to help the latter get his revenge on the people who murdered his family and burned down his house. Moreover, Sebastian seems to have his agenda in the story, although he mostly keeps himself for himself instead of giving away his intentions.

There is also the fact that Sebastian's charming and sophisticated personality has made him a fan favorite, to the point that there is an argument to be made that he has been the face of the franchise since its beginning in 2006. It is also worth pointing out that he claims he isn't capable of showing emotions, but that adds a degree of complexity when viewing certain scenes in the series.

The contrast between his facade as a loyal servant and a demonic being who has no moral compass is a major appeal of his character, which is why he has become so beloved in the community as a whole. It makes his character a lot harder to predict, thus making him feel like a looming shadow who may have his intentions throughout the story as a whole.

Final thoughts

Regarding how old is Sebastian in Black Butler, there is enough evidence to suggest he is several centuries old, but not enough to pinpoint a specific age. Therefore, it is fair to say that he has lived for a long time, especially given his demonic nature, but the series never confirms how old he is. There is an argument to be made that this mystery has been intentional to give more mystery to the character.
