The eponymous character. Ciel's mysterious but charismatic and highly skilled butler; he appeared out of nowhere with Ciel two years ago and is rarely far from his master's side. In reality, he is actually a demon who has made a Faustian pledge to Ciel; in exchange for utter obedience to Ciel, and assisting him in finding and killing the murderers of Ciel's parents, Sebastian will be allowed to kill Ciel and take his soul once his service is ended or Ciel dies.
See his folder here for tropes regarding him.
- Badass Crew: The reason why the servants, except for Tanaka, are so bad at looking after the mansion is because their master actually hired them as his special forces. When it's time to take down their master's enemies, it's their time to shine.
- Only One Name: None of them have surnames mentioned or don't have them in the first place like in Finny's case.
- Undying Loyalty: They are all absolutely loyal to their master and their main life purpose is to protect him. After the return of the undead real Ciel, Finny, Mey-Rin, Bard, and Snake are the only people who don't hesitate to take their master's side and rescue him from arrest even though he has been revealed to be an impostor. Tanaka stays behind to work for the real Ciel, but his real motives are still questionable.

The maid of the Phantomhive household. She wears Opaque Nerd Glasses given to her by Ciel that limit her eyesight and prevent her from viewing objects correctly at close-range, which causes her to be clumsy when doing her chores. Mey-Rin is actually a professional sniper and due to her sharp binocular vision, she does not require a scope to aid her.
- Action Girl: She's a Cold Sniper who can leap from roof to roof and go Guns Akimbo with two rifles.
- Adaptation Dye-Job: Her hair and eyes are red in the manga, while in the anime her hair is closer to a shade of magenta and her eyes are brown.
- All Amazons Want Hercules: She's a lethal sniper with Improbable Aiming Skills and she has the hots for the unbeatable Battle Butler of her master. Said butler was also the only one to have ever dodged her bullets.
- Animal Motifs: She was given the Code Name "Owl" when she was the sniper assassin of a triad because of her exceptional farsightedness making her able to spot her target from a kilometer away.
- Badass Adorable: You'd never guess this cute and huggable maid girl is a deadly assassin.
- Because You Were Nice to Me: She gave up her intentions of assassinating the Earl and agreed to become the Phantomhive household's maid because they took her in when she was nothing but a sniper assassin with nowhere to go, treated her as a guest and gave her warm meals. To Mey-Rin, who had to steal and kill just to eat cold and moldy bread, this was the greatest act of kindness she ever received. Encapsulated with her concluding lines in her flashback scenes in Chapter 165:Mey-Rin: In the end I couldn't be a proper maid. Every day was another gaffe. But still... Here, there's someone who appreciates me for what I am."
- Beware the Silly Ones: She may be a clumsy girl with a blatantly obvious crush on Sebastian, but despite her incompetence, she's an expert assassin who is very adept in using guns. Mess with her master or anyone else she cares about and you will end up with 1 or 2 holes in you, at least.
- Blessed with Suck: Her farsightedness makes her the perfect sniper. However, it is established that this comes with a proportional drawback in that without glasses she can't see anything close up beyond a hazy blob. When she was stuck working for the triad she couldn't tell if the bread she was given was moldy or a shoe by sight alone.
- Boyish Short Hair: In contrast with her current Girlish Pigtails, Mey-Rin had short hair before the Earl Phantomhive made her his maid and she only become feminine afterwards.
- Brats with Slingshots: In her childhood, Mey-Rin used slingshots to knock off the earrings of rich women so other street kids could steal them.
- Children Forced to Kill: Mey-Rin was a Street Urchin who was forcibly recruited by a triad because of her superhuman farsightedness. From a young age, Mey-Rin was used as their tool for assassination. If she refused to follow orders, she would have been killed like the triad did to her two friends.
- Cold Sniper: When she takes off her glasses, Mey-Rin changes from cute clumsy maid to ruthless sniper who won't hesitate to shoot you dead.
- Covered with Scars: Her arms are covered with scars that are leftovers of her life as a sniper of a triad.
- Covert Pervert: She gets really heated up over potential steamy situations with Sebastian, whether he's with her or Ciel. In the first anime, also sprouts a Nose Bleed at the sight of Pluto with Angela when she believes they are lovers, and is very appreciative of the view when they encounter Pluto wandering naked around the fens. Also from her time in Houndsworth, upon seeing a man training a dog, the dub renders her as saying,"I'd let him pet me, yes I would!"
- Crippling Overspecialization: Her extreme farsightedness and upbringing as an assassin of a triad made her only good at sniping. That's why she's so bad at being a maid.
- Crouching Moron, Hidden Badass: She's a clumsy maid who often breaks things and mixes up shoe polish for wood polish on a regular day, but if anyone threatens her employers, she will blow their brains out.
- Curtains Match the Window: Although they usually aren't visible, Mey-Rin's eyes are red like her hair.
- Cute Clumsy Girl: Justified. She's absurdly farsighted and the glasses Ciel gave her aren't the right correction. As a result, she frequently trips, knocks things over, and breaks them when doing her job as a maid. She also mistakes products like shoe polish for wood polish and misreads instructions because her eyes can't read the tags.
- Dark and Troubled Past: She was a Street Urchin who lost her parents to an epidemic. Forced to fend for herself in a foreign country, a young Mey-Rin cooperated with two other street boys and used her farsightedness to steal expensive earrings from rich women. One day, during their usual schemes, Mey-Rin's friends were caught by two men from a triad who ordered Mey-Rin to make a demonstration of her aiming skills or she and the boys would be killed. The man was impressed by Mey-Rin's demonstration, but only her life was spared and she was Forced to Watch as her two friends were thrown off a building. The men decided Mey-Rin's eyes were useful to them and they made her work with them as an assassin. Ten years later, she was given the mission to kill the Earl Phantomhive, but Sebastian defeated her and instead of killing her, he offered her to work for the Earl Phantomhive.
- Death Glare: Her default expression when she takes her glasses of, and for good reason.
- Fully-Clothed Nudity:
- Reacts this way in season 1 of the Anime, when she and the other servants go for a swim, and is embarrassed by her Victorian-style swimsuit, which by modern standards is extremely modest.
- Exhibits the same reaction in Chapter 147 of the manga while wearing a thigh-length Qipao.
- Girlish Pigtails: She has her hair tied in high pigtails. It contributes to her Cute Clumsy Girl image.
- The Glasses Come Off: When she takes off her glasses, she's ready to shoot you down. And don't make the mistake of trying to distance yourself from her.
- The Gunslinger: She's a master sniper who almost never misses her target.
- Guns Akimbo: Her rifle proficiency and marksman-level eyesight and gun control allows her to dual-wield bolt-action rifles with relative ease, as evidenced in the Book of Circus Arc. Noa's Ark Circus members Peter and Wendy found out about this the hard way, the latter by way of a Boom, Headshot! One-Hit Kill.
- Harmful to Minors: The little Mey-Rin saw as her two friends from the street were thrown off a building and smashed against the concrete. Then, she was forced to start her job as a sniper assassin when she was just a kid.
- I Owe You My Life: Mey-Rin was the sniper assassin of a triad and she was assigned to kill the Earl Phantomhive. Of course, because of Sebastian protecting the Earl, Mey-Rin's assassination attempt failed. The triad were going to have Mey-Rin killed for her failure, but Sebastian saved her and convinced the Earl to take Mey-Rin in as a maid of the Phantomhive Household because her sniper skills would be very useful to protect the Earl from future threats. This way, Mey-Rin was rescued from spending the rest of her life on the run from the triad and she finally was given a place where she felt at home and could be herself.
- Improbable Aiming Skills: Mey-Rin never misses her target (see character quote.) Her eyes let her spot and shoot down anyone and anything from over a kilometer away, even if it's something as small as an earring.
- It Was a Gift: Ciel was the one who gave her her glasses, so she cherishes them and refuses to give them up even though they aren't the right correction. Later on, Ciel does finally buy her new glasses that allow her to see at close-range better.
- Let's Get Dangerous!: All of the servants are this to an extent, but unlike Bard (who's laid back but still professional when fighting) and Finny (who reacts with a certain naivety to violence), Mey-Rin is dead serious when she's needed in a fight. She provides the most jarring contrast between her personality on and off duty.
- Meganekko: She fits the character archetype of the bespectacled Cute Clumsy Girl. But that's only when working as the Earl's maid; if you make her take off her glasses, she reverts to the Cold Sniper she was before meeting the Earl and Sebastian.
- Meido: She works as a maid at the Phantomhive household and she deeply enjoys it, as she's made clear several times.
- Ninja Maid: She really sucks at the regular housework, but she's an amazingly efficient sniper with no compunctions about killing anyone who threatens her employers.
- Nosebleed: Her appearances in the first two Anime seasons display this especially towards Sebastian. This was later averted as of the Book of Circus Arc, probably to emphasize her skills as a marksman more.
- Obfuscating Stupidity: While all of the servants can spring into action should the need arise, the contrast between Mey-Rin's ditzy maid persona and her serious weapon master one is the most jarring. Baldroy's casual demeanor is evident at all times as is Finnian's childish exuberance, but Mey-Rin almost becomes a different person when she gets into the field.
- One of the Boys: When she was a kid living in the streets, she hung out with two boys who were her partners in crime. Since Mey-Rin dressed and talked masculinely back then, she really looked like another boy in her little gang.
- Opaque Nerd Glasses: She wears a pair of large round glasses that hide her eyes. Somewhat justified as they neutralize her absurd farsightedness when not going Guns Akimbo with scopeless rifles.
- Ore Onna: In her childhood, Mey-Rin used the masculine first-person pronoun 'ore' because she was a tomboy living on the streets. She switched to female pronouns after she became the Phantomhive household's maid.
- Parental Abandonment: In the manga, Mey-Rin and her parents came to England on a tea clipper. However, some time afterward, her parents died in an epidemic, and Mey-Rin was left to live in the streets of a foreign country when she was a child.
- Peek-a-Bangs: Before Ciel and Sebastian recruited her service, Mey-Rin used to have her bangs covering her right eye.
- Professional Killer: She was an assassin working for a triad against her will. She was sent to assassinate Ciel because his actions as the Queen's Watchdog were obstructing the triad's criminal business. Sebastian defeated her and persuaded her to use her skills for the Earl.
- Red Eyes, Take Warning: When she reveals her red eyes under her glasses, you're dead.
- "The Reason You Suck" Speech: Towards Jane in Chapter 165:Mey-Rin: Serving a bastard of a master who deceives and exploits women... I'd never do that, even if you offer me all the money in the world.
- Reluctant Fanservice Girl: She's extremely embarrassed when she's put in a Qipao because bare legs were seen as very indecent for Victorian women.
- Rescue Romance: Mey-Rin has a big crush on Sebastian, the man who saved her from being killed by her triad after failing her mission to assassinate the Earl Phantomhive and gave her a place to belong by convincing the Earl to hire Mey-Rin as the household maid.
- Samus Is a Girl: During Mey-Rin's first meeting with the Earl and Sebastian, neither of them were expecting to discover the deadly sniper Owl was actually a young woman.
- Scars Are Forever: In the manga, when Mey-Rin and Ran Mao are changing their clothes to maid outfits at Baron Heathfield's manor, Mey-Rin has several scars on her right arm. She lacked them in original anime as the detail hadn't been established by that point.
- Slasher Smile: Sports a particularly impressive grin at the end of Chapter 165◊.
- The Smurfette Principle: She's the only female servant at the Phantomhive mansion.
- Spell My Name with an "S": Also spelled Mei Lin/Mei Rin/Maylene/etc. Yen Press' official transliteration is Mey-Rin, though chapter 163 shows that her name is actually '美玲' (Mei-Ling).
- Stocking Filler: She wears thigh-high stockings, which are held up by a garter belt.
- Street Urchin: Mey-Rin's parents were immigrants who died from an epidemic, leaving her an orphan trying to survive in the streets of London by helping other orphans steal.
- Sugar-and-Ice Personality: When she's working as a maid, she's cheerful, somewhat goofy, and swoons over Sebastian. When she's sniping, she's cold, calculating, and ruthless.
- Super Senses: Her far-sight is so damn good that her rifles don't need scopes; Mey-Rin can shoot down targets at a kilometer of distance in just one try.
- Used to Be a Tomboy: When she was a child, Mey-Rin dressed like a boy, had Boyish Short Hair and used masculine speech patterns. After the Earl Phantomhive took her in as a maid, Mey-Rin became the girly Cute Clumsy Girl we are familiar with.
- Would Hurt a Child: When Wendy and Peter try to bisect Finny, she shoots Wendy in the head. When confronted by Peter, she shoots him in the shoulder and pins him down with gunfire, before sniping him when he tries to escape.
- Yaoi Fangirl: She has a crush on Sebastian, but doesn't mind him being all over Ciel and gets huge nosebleeds at the sight.

Live actors: Tsuyoshi Koyama ; Iwasaki Dai ; Noboru Washio [2013-Current] (Musical)
The chef of the Phantomhive household. However, he never makes anything edible as he uses weaponry such as flamethrowers to cook, believing that cooking is an art requiring explosions. He's a former soldier and while terrible at cooking, he is shown to be capable of taking advantage of his surroundings, such as using fine flour to create an explosion.
- Adaptational Nationality: Baldroy is an American in the manga, but is shown to speak with a lower class British accent in the anime and his flashback shows him serving in the British Army, though for some reason he still doesn't know the words to God Save the Queen.
- A-Team Firing: Lampshaded when blasting up the kitchen with the Gatling Gun, Dagger and Beast manage to dodge him, and he expends all his bullets. He laments that while it has a very good number of rounds, the device is made for rapid fire and not accuracy, though in the chaos he did manage to kill Dagger.
- Chef of Iron: His food isn't good mostly because he's blowing people up with it.
- Cradle of Loneliness: When Sebastian found him, he was cradling one of his dead friends.
- Crippling Overspecialization: He sucks at cooking and housework because he's only good at handling weapons to kill people.
- Crouching Moron, Hidden Badass: While he typically comes across as hopelessly incompetent when it comes to cooking, cleaning and just about every other domestic task, Baldroy is an experienced combatant who can hold his own in a fight.
- Dark and Troubled Past: Lost everyone he cared about on the battlefield.
- The Engineer: A combat type. His real specialty is maintaining weaponry at the mansion that he uses in case of intruders.
- Gatling Good: Keeps it in the kitchen, of course.
- Lethal Chef: The food he cooks is always inedible, but it could be better if he tried cooking it the right way instead of using flamethrowers. Justified; this is actually a carryover from his days as a soldier. Back then you had to prepare your food quickly or you were likely going to miss your chance to eat before the fighting picked up again. He's just never lost the mentality.
- Only Sane Man: While all the servants are aware Sebastian is no normal butler, Baldroy seems to be the only one to ever suspect there's something sinister going on with him.
- Pillow Pistol: The Book of Murder arc reveals that he sleeps with a pistol under his pillow. Bard almost shoots Sebastian when he wakes him.
- Shell-Shocked Veteran: He had more than enough experience with the horrors of war. His past does seem to haunt him, and he still thinks like a soldier.
- Smoking Is Cool: He's a chill and laid-back ex-soldier who is rarely seen without a cigarette on his mouth.
- Spell My Name with an "S": Baldroy/Baldo/Bard.
- Stuff Blowing Up: As a former soldier, he has knowledge of weaponry including explosives.
- Technical Pacifist: As much as he enjoys explosions, he seems to like not having to kill people... unless necessary.

The gardener of the Phantomhive household. However, it seems every time he tends to the garden, it is destroyed through an accident caused by his clumsiness. Finnian was a test subject in some human experiments that gave him Super Strength and was taken in by Ciel after he ran away from his cell.
- Badass Adorable: Finny's got the excitement of a little kid, and the strength of several men.
- Because You Were Nice to Me: His master the Earl was the first person who ever treated Finny as a human being instead of a disposable experiment and gave him a real name and a good home. For these reasons, Finny is going to protect his master no matter what.
- Beware the Nice Ones: Finny is a lovable and kind-hearted young boy... unless you're a threat to his master and the manor. In that case, you better run because Finny won't hesitate to kill you with a single punch.
- Bishōnen: He's more cute than pretty, but he's still a boy with really feminine features.
- The Caretaker: Forced to look after Ciel during the latter's Heroic BSoD in the Witch Forest arc, as he's the only one of the servants Ciel will let get close to him.
- Caring Gardener: He's happy that the Earl made him his gardener because Finny can now grow life instead of destroying it as he was taught to. However, he's not good at the job since he often ends up ruining the garden and Sebastian has to clean up his mess.
- Crippling Overspecialization: His Super Strength and past as a test subject makes him only good for breaking stuff or people.
- Crouching Moron, Hidden Badass: May not know much about gardening yet, but he uses his strength more proficiently than what he normally implies; which is usually none at all.
- Cute Bruiser: An absolutely adorable and childish young boy with superhuman strength that makes him capable of crushing nearly anything in his path.
- Dark and Troubled Past: The poor boy was captured and cruelly experimented on. When he wasn't left alone in a dark cell, he was given numerous unsafe injections and saw his fellow subjects killed with a bullet to the brain. He killed the scientists before they killed him too and ran into Ciel, who decided to take him in.
- Declaration of Protection: He swore to protect his saviour Ciel and the new home he gave him.
- Does Not Know His Own Strength: He's aware of the Super Strength his body has as a result of the experiments he was subjected to, but he hasn't learnt to control it properly to do his job at the manor. When blowing on hot milk to cool it down, he accidentally breathes at fifty mph.
- Excellent Judge of Character: He's able to tell that the servants can trust "Jeremy," and he can tell that something is off with the true Ciel.
- Hair of Gold, Heart of Gold: He has blond hair and he's very innocent and optimistic... of course when in battle it's a different story.
- In a Single Bound: He can jump and land great distances across gaps and depths and while it still hurts, it doesn't cost him any great damage.
- In-Series Nickname: He's called "Finny" for short.
- I Owe You My Life: Before the Earl found him, Finny was nothing but "Test Subject #12" locked up in a cell. The Earl gave him a home by bringing him into his manor and gave him a real name, which allowed Finny to develop into his own person. Because of this, Finny swore to protect the Earl from anything that tries to harm him.
- Keet: He's very cheerful and excitable like a cute kid.
- Kiddie Kid: 16 years old yet he has the naivete and behavior of someone half his age. While such traits can make him seem adorable, it does admittedly become problematic at times, such as in the Phantomhive Manor Murders Arc. As he is causing a ruckus over Arthur suggesting to examine Sebastian's apparently dead body as part of the investigation, Ciel tells him to leave the room if he is going to act like a child as he is being in the way. This apparent stunt in emotional maturity is probably due to his time as a human experiment in which he was isolated from society.
- Lightning Bruiser: Not just strong but quick too. Seen especially when carrying Sullivan out of the forest in chapter 100.
- Meaningful Name: Ciel named him after Fionn mac Cumhaill, a mythical hunter-warrior of Celtic Mythology, because of Finnian's blond hair and great strength.
- Spell My Name with an "S": Some call him "Phinnian" as well...
- Super Strength: Because of the human experimentation he was subjected to, Finny has strength comparable to an elephant.
- Super Toughness: He can get his head smashed against concrete and brush it off as a scratch.
- ¡Three Amigos!: With Bard and Mey-Rin.
- They Would Cut You Up: His Super Strength comes from surviving human experiments.
- You Are Number 6: He was referred to as #12, as shown by his tattoo, during the experiments.
Voiced by: Shunji Fujimura (JP), R. Bruce Elliott (EN)
The steward of the Phantomhive household and the only one of the servants who has worked for the household since before the death of Ciel's parents.
- Ambiguously Evil: In the Blue Cult arc, he's the only servant who doesn't follow "Ciel", claiming he's going to serve the real Ciel instead. However, it's still questionable which of the twins he's really loyal to because he doesn't seem happy to work for the real Ciel.
- Art Shift: Usually drawn Super-Deformed. When he needs to be serious, he's drawn the same as the rest of the cast.
- Battle Butler: He was the butler of the previous Earl Phantomhive and has the combat skills needed to handle the dangers of the job.
- Cool Old Guy: He's the only servant Sebastian tolerates because he's just that cool. That and he doesn't get in the way.
- Crouching Moron, Hidden Badass: He's usually seen drinking from a Japanese tea cup and commonly seen in a Super-Deformed form. Despite his appearance, Tanaka is a master of bartitsu and just as dangerous as the other servants when he needs to be.
- High-Class Glass: He wears a monocle and he's the most dignified of the servants.
- Loyal to the Position: Unlike the other Phantomhive servants who are specifically loyal to the current Earl, Tanaka serves whoever is the head of the Phantomhive household at the moment. When the real Ciel returns to take back his position from his twin, Tanaka is the only one who doesn't leave to help Ciel's twin as he claims he'll only serve the head of the Phantomhive family.
- Master Swordsman: He's a master of bartitsu capable of cutting bullets in half in midair.
- Non-Standard Character Design: Playing with a Trope. He's usually designed deformed and simple compared to the cast, but when he's serious, he's drawn the same way as the rest of the cast and goes back to his deformed mode, once he's said what's needed to be said.
- Old Master: He may be old, but he shows why he was once the butler of the previous Earl Phantomhive when he takes out his sword and starts cutting through bullets. He does know he isn't the same fighter as when he was young and leaves most of the action to the younger servants.
- Old Retainer: He has served the Phantomhive family for decades and is something like a grandfather figure to the current Earl.
- Parrying Bullets: He's fast enough to cut bullets in half in midair with his sword.
- Secret Keeper:
- In the anime, Tanaka was told directly by Vincent Phantomhive that Queen Victoria would be the one responsible for his death, but was also asked to keep this from Ciel. At the end of the first season, Sebastian gives Tanaka's diary to Ciel, which reveals this.
- In the manga, Tanaka is the only servant who knows that Ciel has a twin brother, although he didn't confirm that the current earl took his twin's name until the revived real Ciel appears.
- Signature Laugh: "Hoh hoh hoh"
- Super-Deformed: In his normal appearance, he's drawn cartoony and a lot smaller than the other servants. When serious, however, he's almost as tall as Sebastian.

- Half-Human Hybrid: According to Joker, he's a half-human, half-snake.
- Hand-Hiding Sleeves: His first outfit has long sleeves that cover his hands.
- Hates Being Alone: One of the reasons why he accepts Ciel's offer to join his staff is because he felt very lonely without his circus friends and working at Ciel's mansion lets him find new friends in the other servants.
- Horrible Judge of Character: Can be played straight or averted depending on how well you think Ciel lied to him about wanting to cooperate and find the 'missing' circus members.

- Idiot Hair: While not an idiot, Snake has a distinct cowlick. Doubles as Expressive Hair.

- Mystical White Hair: As if being a mysterious half-snake man wasn't enough, his white hair makes him stand out even more.
- No Social Skills: Really not good with people, due to his early isolation and snake-like features. Also not sure how cake works.

- The Quiet One: He never seems to speak for himself, only translating for his snakes.
- Scarily Competent Tracker: He used his snakes to follow Ciel's scent after the circus arc. Though he ended up going to the wrong house and it was actually thanks to Sohma and Agni he found Ciel, since they had mistaken Snake for a friend of Ciel's so they greeted him warmly and sent him to Phantomhive Manor.
- Shrinking Violet: Shows signs of being one when boarding the Campania with Ciel due to his appearance.Ciel: "You aren't used to crowds?"Snake: "I look different from everyone else, and since I'm with you, people will laugh at you too. Says Dan."
- Sixth Ranger: He joins the Phantomhive manor's staff midway through the series while all the other servants have been working for the Earl since the beginning.

- Took a Level in Cheerfulness: Starts to be more expressive after joining Ciel's staff.
- Verbal Tic: Whenever he speaks, he ends the sentence with "..says (Snake's name)", even if they include personal pronouns referring to himself.
