(Grell isn’t in this list because I’ve actually made a separate post just for him before. You can find it here if you’d like to look at it!)
Yana Toboso (the Black Butler creator) has stated that Undertaker’s character design was based upon the design of a character of a pirate manga that she had planned before she started working on Black Butler.
2. William T. Spears
Aside from being the only Grim Reaper to reveal his middle initial as T, William had a lower grade average than Grell back when they were still Grim Reaper students. Grell had an A average while William only had a B average.
3. Ronald Knox
There was a lot of designs made for Ronald’s character before his look was decided upon. One of these rejected designs actually ended up being used for Cheslock’s character design!
Othello shares his name with both a play (and the respective main character of the play) by Shakespeare, and with a board game. Reversi is a strategy board game for two players, and has been marketed under the trademark Othello. Othello actually wears the pieces of this board game on his coat pocket.
Ludger thinks that Grell is too flashy and extravagant.
In a flashback in chapter 105 a silhouette of Sascha was shown alongside a noose, implying that he committed suicide by hanging when human.
“If someone means any harm against the Young Master in this mansion, no matter who they are, these servants will have no mercy on them” – Tanaka
Sebastian is the one who taught Finnian and Mey-Rin how to read
Baldroy is afraid of snakes, which is why whenever Snake and his snakes appear at the Manor he hides behind Finnian. Baldroy’s mentioned before that his fear stems from an incident that happened in Arizona, though we don’t know exactly what that incident is…
In the early drafts of the manga, Tanaka had thicker hair. Toboso has also revealed that his character was modelled after his late voice actor, Shunji Fujimura
As shown in chapter 87, it seems that Finnian can actually speak some German!
In the first episode of Black Butler Mey-Rin’s eyes are blue, but then they are hazel for the rest of the anime… However, in the manga her eyes are actually red
Snake is said to be half-snake, so it makes sense that his skin has some scales on it. But he seems to be quite self-conscious about this, as he was insecure about it when two ladies in Campania were talking about his skin and its snake-like properties. Being a human-snake hybrid though does allow him to understand snakes, allows snakes to speak though him, and also means that he can fall under the influence of a snake charming flute (they make him dizzy and faint)
Before Toboso settled on Ciel, some of the other names that were considered for the character were Estelle, Aster, Angel, Angelo, Fate, Celestial, Rain, Lapis and Voltaire. Ciel’s last name also could have been Faust or Ghosthive…
Ciel’s birthday is on the 14th December, which is also the date of Prince Albert’s death. Ciel’s ‘deathday’ though is on the 26th August, which is also Prince Albert’s birthday
Ciel has stated that he doesn’t like to hang out with ‘weirdos’, but everyone that he hangs out with regularly aren’t exactly what one would consider to be ‘normal’
Ciel is the 2nd most popular character in the series, second only to Sebastian
“Society has monsters lurking in it that are far nastier than a demon like me” – Sebastian (to Ciel)
Sebastian’s last name, Michaelis, is derived from the Japanese word ‘mikari,’ meaning ‘repayment’
Sebastian is said to be based upon an inquisitor from the 16th century who wrote about the classification of the demons of Hell and about possession
Whenever Sebastian does something that humans find impressive he always says, “I am simply one hell of a butler.” But in Japanese, what he says can also be read as, “I am both a demon and a butler”
Sebastian is first introduced as a crow – but this only happens in anime. In the manga Sebastian is first revealed in his ‘true form’
Demons cannot taste. So when Sebastian ‘tastes’ the curry, we can assume that he can taste to some extent – just maybe not in the same way that humans can. This explains why he needs practise to get his cooking right, because he needs to learn what tastes good to humans?
When Sebastian raises a handkerchief cover his face in episode 17, this suggests that demons have an aversion for salt. However, no other objects seems to have an effect on Sebastian – as he has no problems with Churches or rosary beads
Sebastian is fluent in French and Latin, and can also speak German and East Franconian
There is a definite resemblance between Sebastian and Vincent. This is actually intentional, though Yana Toboso hasn’t revealed why she chose to draw them this way
Back in the Victorian era butlers were called by their last name. So that means that Ciel should technically be calling Sebastian ‘Michaelis’ and the other servants should be calling him ‘Mr Michaelis’
Sebastian is shown to love cats, though it’s implied throughout the series that he hates dogs. Ironically, Ciel named Sebastian after his late dog…
In early drafts of Black Butler, Sebastian’s hair was styled with a 7:3 ratio parting. However, Toboso’s editorial staff didn’t like this hairstyle, so she had to change Sebastian’s hair to that of a middle part
