Finnian (フィニアン, Finian), often called "Finny" or "Finni," is the gardener of the Phantomhive household.
Finnian is a teenage boy with large turquoise eyes and short strawberry-blond hair clipped back with five red bobby pins—two on his right and three on his left.
Finnian usually wears a plain top with red piping around the collar and plaid pants along with black knee-high boots. He occasionally sports a straw hat—which he adores because it was given to him by his young master—around his neck to conceal the mark, "S-012," which he was branded with during his time as a test subject.
Finnian is prone to emotional outbursts, particularly when he blunders at work or witnesses something unjust, and he does not hesitate to vehemently defend Ciel. According to Sebastian, he is "an idiot with a bad memory."
Finnian has acquired superhuman strength after he was experimented on. He is able to lift marble statues with ease, for instance. Having constantly been imprisoned during his time as a test subject, he consequently enjoys being outdoors and working as a gardener at Phantomhive Manor.
Prior to working for the Phantomhive family, Finnian was held captive as a test subject, kept indoors in a certain institution, branded with the mark "S-012," and frequently received injections of an unknown substance, which his superhuman strength is attributed to. His fellow inmates were slain in front of him.
One day, a raid was conducted at the institution. Finnian's captors intended to destroy all evidence of the institution's illicit activities. The doctor who killed his fellow inmates was about to kill him next. Nevertheless, he managed to kill the doctor and escape the institution and was found by Ciel and Sebastian.
Afterward, Finnian was admitted to the Phantomhive household as the gardener. Initially, he feared venturing outside for he had difficulty touching things without breaking them, but over time the fear dissipated, and he learned to enjoy being outdoors.
Black Butler Arc
Finnian, Baldroy, Mey-Rin, Tanaka, and Ciel Phantomhive observe the match between Sebastian Michaelis and a martial artist outside Phantomhive Manor. Sebastian vanquishes his opponent, which impresses them. Afterward, Sebastian instructs them to perform their duties. When the Phantomhive servants make a mess prior to and during Chlaus’s visit, Sebastian cleans up after them and rectifies the various issues.
At one point, the Phantomhive servants attempt to exterminate rats, which have been biting the wires in the manor. Sebastian effortlessly gets rid of the rats. After Ciel is taken by Azzurro Vanel and while Mey-Rin is delivering to Sebastian the ransom letter she has received, a sniper attacks, but fails. Sebastian tells the servants to clean and cook and leaves after declaring that he will return before dinner. Later, Sebastian returns with Ciel, and the servants welcome them home. When the servants discuss the Azzurro Vanel case, Sebastian orders them to do work.
Red Butler Arc
In the morning, Sebastian Michaelis assigns Finnian, Baldroy, and Mey-Rin their individual tasks for the day while Tanaka loiters. When the Phantomhive servants make a mess, Sebastian cleans up after them and rectifies the various issues. After Sebastian discovers that his chocolate statue is missing a head, he and the other Phantomhive servants hunt down Tanaka, assuming he is the culprit, but it is actually Ciel Phantomhive.
On December 14, the Phantomhive servants prepare for Ciel's thirteenth birthday, which coincides with Elizabeth and Francis Midford's visit. Sebastian redirects Francis away from the disasters the servants inadvertently cause. They all celebrate Ciel's birthday.
Indian Butler Arc
The servants accompany Ciel, Sebastian, and Soma to the curry competition. The servants are jubilant when Sebastian's curry dish garners rave reviews from the judges. Queen Victoria arrives, to their shock, and crowns Sebastian the winner. The servants rejoice.
The servants are pleased when Soma reconciles with Agni and stunned when Queen Victoria refers to Ciel as "boy." They congratulate Sebastian on his victory and enjoy the view of the evening sun. Soma hugs Ciel and cries over Mina while the servants look on.
The next day, Sebastian assigns Finnian, Baldroy, and Mey-Rin their individual tasks for the day while Tanaka loiters. Agni helps out, as well. The servants voice their appreciation for their current lives at the manor.
When the first-string circus members (excluding Snake, Joker, and Doll) attack Phantomhive Manor, Finnian, Baldroy, and Mey-Rin take on the offensive after Jumbo's assault on Finnian. Jumbo runs into a just-awoken Finnian, who tells him to come back later. Jumbo hits him in the head and leaves, thinking that he has killed him. However, Finnian stands up and smashes Jumbo into the wall. Jumbo is left alive long enough to yell to Peter and Wendy to escape, but Finnian smashes his head for the second time, killing him.
Peter and Wendy then attack Finnian using whip-like weapons. They made a hole in his hat, and he throws heavy items at them in return. He yells at them that they shouldn't have damaged the hat that Ciel gave them. He then states that he loves this place, and he will do anything to protect it. The two then decide to string a wire between them and slice Finnian in half. Before they can do so, an unseen sniper (who is revealed to be Mey-Rin), shoots and kills Wendy with a single bullet to the head. Peter then abandons pursuing Finnian to take out Mey-Rin.
Inside the manor, Finnian goes to Baldroy's aid and lifts heavy statues to throw at Beast and Dagger. They flee and eventually end up in the basement. Baldroy takes out Dagger with a machine gun, which also shoots loads of flour into the air in the process. Finnian goes to help Baldroy again, creating a hole in the wall, and he helps Baldroy out of the kitchen. He then watches as Baldroy throws a lit match into the kitchen, creating a massive explosion that kills Beast.
Later, when Ciel and Sebastian return to the manor, Mey-Rin, Finnian, and Baldroy are reprimanded for destroying much of the mansion in eliminating the first-string circus members. They are set to work cleaning up the mess. When Nina Hopkins arrives, Baldroy and Finnian go to greet her, but are blatantly ignored, much to Baldroy's annoyance.
Phantomhive Manor Murders Arc
Charles Phipps and Charles Grey arrive at Phantomhive Manor to deliver a message. On the way out, they pass by Finnian. Phipps comments that "this side is still too easy" and appears to attack Finnian. However, it is shown that he merely wanted to fix Finnian's hat, which he did by sewing a flower over the hole. This surprises Grey; it leaves him wondering if Phipps always carries a needle while Finnian waves goodbye and profusely thanks Phipps.
When Georg von Siemens is found dead, Finnian helps Baldroy move the body to the cellar. When asked for their alibis, the servants say that they were cleaning together. When Ciel is accused of being the murderer, Finnian tries to defend his master, stating that Ciel would never do such a thing. Ciel commands him to stop. While sleeping after the party, Sebastian wakes Finnian up. He then tells Finnian to care for the fireplaces first thing in the morning. Finnian is the first to find Sebastian dead the next morning. He and Mey-Rin try to console Ciel although he is also crying; Finnian even gives Ciel his coat. When the other guests begin discussing how Sebastian was killed, he yells at them to stop saying such insensitive things in front of Ciel. Tanaka, whom Ciel appoints as his new temporary butler, gives the servants their jobs and sends them on their way.
The following morning when Patrick Phelps is missing, everyone tries to get into the room he was staying in, but it is locked. Finnian is about to break the door down, but Charles Grey beats him to it, using a sharp sword to cut the door into pieces. Later, Arthur Conan Doyle tries to put the three deaths in order. The servants state that Sebastian talked to them all the night of his murder, and this proves he was the last to be killed.
Ciel is asked to lead a group to see if Sebastian had the key to Ciel's room, but he asks Finnian and Baldroy to guide them to the bottom floor. Finnian becomes distressed when Arthur and Ciel begin searching Sebastian's body in the cellar. He then yells at Arthur, but is reprimanded by Ciel, who tells Finnian that if he is willing to having such a meaningless conversation, he should exclude himself from solving the case. The group then goes to search Sebastian's bedroom. They search through the entire room, but cannot find the key. Instead of the key, they discover a multitude of cats in Sebastian's wardrobe.
The key is still not found after all the luggage is checked, and Lau comments that Sebastian might have thrown it out the window. Finnian volunteers to search for it outside, and Mey-Rin decides to do the same. Ciel tries to stop them, but he exclaims that he wants to solve the case and runs outside with Mey-Rin. Baldroy follows them to try to get them back inside, but they refuse. Finnian reminds them that everything they have is because of Sebastian and Ciel and begins to cry. Baldroy reminds them of their job to protect the manor and Ciel. Tanaka then offers them an umbrella and tells them that they do not have enough food. They all go to the kitchen and begin planning how to deal with the lack of food. Upon the discovery of Jeremy Rathbone, the servants capture and tie him up. They bring him to Ciel while Finnian searches Jeremy's pocket for a ticket which proves Jeremy's innocence. When Jeremy is freed, he asks that the bodies should be placed in separate rooms, which the servants were left to do. Finnian says he thinks they can trust Jeremy, but Baldroy and Mey-Rin tell him that putting too much trust in others will only get his feelings hurt.
Later, the servants are trying to figure out what to serve for dinner since they are out of provisions. Jeremy comes in, and he helps them prepare dinner out of the few ingredients and herbs they have. After supper, the servants watch as everyone compliments the food.
When everyone is waiting to see who Patrick's killer was, the servants all stand around Ciel with makeshift weapons to protect him. After Jeremy reveals who the killer is, Finnian brings up Irene Diaz's mysterious "dark red liquid." Mey-Rin and Grimsby Keane yell at him, but Jeremy explains anyway. His explanation of a type of leaf, which Finnian recognizes as "red parrilla," leaves the servants relieved.
At Sebastian's funeral, Finnian takes part as one of the pallbearers. The funeral attendees begin to head back to the mansion after Sebastian has been buried, but before leaving, Finnian notices something: the bell next to the base of the headstone begins to ring, even though there is no wind. He then begins digging Sebastian's grave, and the others follow him. When Sebastian is completely unearthed, and they find that he is still alive, the crying servants and Elizabeth jump on and hug him.
Luxury Liner Arc
Sebastian informs the servants that there will be a new servant. Snake's snakes then enter the room and cause Baldroy to hide behind Finnian. Finnian allows one to crawl around him and calls it "friendly." Snake begins naming all of his snakes, while Finnian begins talking to the snake crawling on him. Later, he is showing Snake around when Elizabeth shows up.
A month after the unprecedented accident of the ship Campania, Elizabeth and her brother Edward celebrate Easter at Phantomhive Manor. Elizabeth decides to do a traditional game of egg hunting. Upon Charles Grey and Charles Phipps' arrival, Sebastian applies small changes on the egg hunt's mechanics by adding a few deviations from the game of egg tapping. This leads to Finnian being paired up Snake .
Finnian starts looking for eggs with Snake's (and his snakes') guidance, at one point leaving his partner behind. He then comes back with a bunch of eggs and a 'burned up' because one of the eggs blew up in his face. Yet, he finds Snake dizzy and lying on the ground with his snakes, and all of their eggs are already broken. This then disqualifies them from the game.
Public School Arc
Ciel enters Weston College and eventually, gets to participate in the prestigious dormitory Cricket Tournament. Finnian, together with Baldroy, Mey-Rin, Tanaka, Elizabeth, Paula, and McMillan, watches Sapphire Owl's game against Scarlet Fox. Finnian asks Baldroy why members of Blue House get out so fast. Baldroy explains the situation and the game's mechanics and rules, which makes Finnian conclude that the game is going to be a complete disaster. Baldroy mentions he made a special meat pie for lunch. However, Finnian and Mey-Rin find it so troubling because it might lead to Elizabeth getting poisoned. They fear that Edward would conclude that their master is scheming against the Midfords. When lunch comes, the pie Baldroy made mysteriously disappears which relieves Finnian's and Mey-Rin's worries.
Finnian, Mey-Rin, Baldroy, and Tanaka later witness the birth of the second "Miracle of Sapphires" as Blue House wins the tournament. They are also seen at the boat parade and celebrating the victory afterwards.
They all welcome Ciel and Sebastian back home after the pair returns from boarding school. Baldroy explains that Old Man Sam's fence broke and all the sheep escaped. Mey-Rin tells one of the sheep not to eat her dress. Finnian and Snake chase after the sheep as well. Ciel suddenly laughs and tells Sebastian to handle the situation.
Sebastian in the morning supervises the entire household's chores. Then Finnian, Snake, Baldroy, and Mey-Rin accompany Ciel and Sebastian to London. Mey-Rin and Finnian marvel at a large clock, and Baldroy explains that it's Big Ben. Ciel takes all of them with him as he goes through different stores. Finnian wants a straw hat as cool as Big Ben; Sebastian pats his head and tells the haberdasher to just give him a normal one. Finally, they are at a store where the latest Funtom perfume is being sold. A scream suddenly shatters the air, and Sebastian leaves Ciel in Baldroy's care. Later, a crowd of people rushes to buy the perfume, surprising everyone.
Emerald Witch Arc
All five members of the household accompany Ciel and Sebastian to Germany. Standing in the village square, Baldroy complains that his butt hurts since they've been sitting for so long. Shocked, Mey-Rin replies that he's being indecent. Finnian is overheard speaking German by Snake who questions him about it. Finnian replies that he can speak a little. Sebastian instructs them to load the luggage in the second carriage. Then they all proceed into the Werewolves' Forest.
The group suddenly sees a village in the forest, and everyone disembarks from the carriages. Baldroy and Finnian both call out to see if anyone's there. They are all then unexpectedly surrounded by angry villagers who are waving their pitchforks at the group. Finnian, using his ability to speak German, tries to reassure the villages that they are not "rats." Once the situation is resolved, they head with Sieglinde Sullivan to Emerald Castle.
When they arrive at the manor, everyone is amazed at its magnificence. Finnian wants to touch some flowers that he's never seen before, but Sieglinde immediately stops him, stating that the flowers are poisonous. Inside, Sieglinde tells Wolfram Gelzer to show the servants to their quarters. Later, although they all offer to help, Sebastian tells them to rest after their long journey.
During the night, Ciel and Sebastian attempt to investigate the forest clandestinely, but are poisoned by the miasma. When Ciel regains consciousness, Finnian is holding his hand, and Snake is by his bedside. Sebastian reaches his hand out to Ciel when Ciel unexpectedly knocks it away. Ciel then grabs hold of Finnian, surprising everyone. The Young Master then exclaimed "Ciel doesn't want pain anymore"; which confuses the servants even more. When Sebastian tries to extend his hand to Ciel again, Tanaka stops him. Ciel suddenly starts screaming about the lights being too dim. Finnian, Mey-Rin, Baldroy, Sebastian and Tanaka hypothesize that their Master's eyesight may have been affected by the attack as well.
In the morning, Sebastian greets all of the servants. After he tells everyone what to do, Sebastian sighs and tells Finnian to take care of Ciel. Finnian is about to happily agree; yet, he shrieks when he understands what Sebastian has asked him to do. Sebastian tells him to feed Ciel some food; if he doesn't have any appetite, he can give him some warm milk with honey.
Finnian then proceeds to care for Ciel. When Ciel refuses to eat, Finnian offers him milk with honey. However, he blows too hard on the warm milk (at the speed of 50 m/s). The milk splashes all over Ciel. Finnian immediately wipes the milk from his master's face. He then suggests that Ciel should go outside with him to get some fresh air, but Ciel declines because he feels that going outside will be scary. Determined, Finnian responds that on the day Ciel gave him a name, he decided to protect him. Ciel softly answers he's not worth protecting. Ciel starts crying; seeing his tears, Finnian also starts crying. Finnian then recalls his past of the life-threatening events that took place at the lab from whence he came. Presently, Finnian tells Ciel that he and Sebastian made him into who he is now. Ciel tells him he doesn't want Sebastian here, upsetting Finnian.
Later on, Sebastian brings Sieglinde to see Ciel. Finnian happily points out that she is speaking English now. Sebastian quietly tells him to clear the dishes and leave. Sieglinde proceeds to change Ciel's bandages.
Sieglinde then addresses the rest of the Phantomhive household. She tells them that Ciel's eyes are fine; the condition was mostly psychological. All of them are extremely relieved. Baldroy immediately suggests that they head back to the manor so Ciel can get some real rest. Mey-Rin states she knows he just wants to cook him some meat. Finnian wants to make snacks, and Snake wants to make scones-all for Ciel. Sebastian sighs and asks them not to increase the workload.
After Sebastian receives John Brown's letter, he heads to Ciel's room. There he asks Finnian to leave for a while. Although Finnian resists with all his strength, he is unable to stop Sebastian. After Sebastian throws him out of the room, Finnian is shocked that Sebastian didn't even flinch under his full strength.
The servants are all reunited after Ciel recovers. Sebastian opens the door, and all of them tumble into the room. Sebastian remarks that they're really rude for listening at their master's door. Finnian lunges towards Ciel, but Sebastian stops him. Ciel smiles and offers him his hand instead; crying with relief and happiness, Finnian takes it.
All of them, Sebastian included, line up by Ciel's bedside. Ciel apologizes for causing the servants stress and concern as a result of his carelessness. He asks them to forgive him. Although they are surprised, he adds determinedly that they will never see him in such a sorry state again. He finally asks that they continue to serve him. They all respond with "Yes, My Lord."
After a few minutes of the servants' light banter, Ciel also makes another request—he wants them to forget how he was until now. Mey-Rin deduces that Ciel also recalls his off-the-charts behavior. Ciel adds that he didn't want to behave like that. Baldroy concludes that Ciel reacted the same way as soldiers. On the battlefield, when they are wounded for the first time, they panic. Sebastian wonders if the attack's aim was purely psychological. When Ciel asks him to explain, Sebastian relates the news about the Queen's letter. He also had the components of the antidote analyzed. When Ciel reads the Queen's letter, everything starts to fall into place. However, he's incredibly annoyed with the Queen's final request—she wants the "little green witch to come to tea."
Ciel knows this request won't be easy to accomplish. Sebastian adds that even the Queen's selfishness is incomparable to Ciel's. Finally, Ciel tells the entire household to make preparations to leave—further instructions will come later.
The entire Phantomhive household is hiding and waiting in the forest. Mey-Rin whispers that it's starting to get noisy. A flare suddenly lights up the night sky. Baldroy yells that 'it's about time'. He adds that their boss is calling them, and they all head out.
In the forest, the household is trying to find Ciel. Snake states Goethe smells Smile "over there." Mey-Rin takes off her glasses, confirming that it is Ciel. When they reach him, he states their retreat plan starts now. They split into two groups and escape. Snake tells Baldroy he can feel them coming. Baldroy asks how he can tell—Snake responds through Arthur that his snakes can feel vibrations with their skin.
At this point, Finnian, Tanaka, and Mey-Rin split up from the others. Finnian rapidly runs while carrying Sieglinde. Remembering the day Ciel and Sebastian explained his new name to him, he switches to lightning speed, unleashing "Subject 12's power." Although the "villagers" keep firing at them, Finnian escapes by jumping off the cliff. Nonetheless, they reach the edge of the cliff and keep firing. Suddenly, Mey-Rin takes out them one at a time, and the rest retreat. She suddenly notices movement; a female officer, Grete Hilbard, appears in front of Finnian, claiming men are useless. Mey-Rin yells at Finnian to run. When Grete fires, Tanaka suddenly appears and uses his sword to cut through the bullets. He tells Finnian to go on ahead; as the Phantomhive servants, they will carry out any order their master gives them.
In the underground room, Diedrich orders Baldroy and Snake to put coal in the furnace of the train. Finnian, carrying Sieglinde and "small" Tanaka, also arrives alongside Mey-Rin. Snake receives Keats, who showed the group the way. Baldroy tells Snake and Mey-Rin to check the oil; he also tells Finnian to open the gate.
Once the train starts, Baldroy tells Finnian to get on. Suddenly, Wolfram arrives. The group panics when they think that he's going to attack them. However, he shoots a soldier who was going to attack Sieglinde. At the same time, Wolfram is shot by the female German officer, Hilde Dickhaut, who yells that he betrayed them. She next aims for the group. Before she can kill them, Sebastian and Ciel arrive just in time to save them. Plunging his knife into her throat, Sebastian states that 'some food escaped from the oven'.
The entire group then arrives at Diedrich's castle; Finnian is carrying Wolfram. Finnian, Baldroy, and Mey-Rin marvel about how big the house is. However, Heinrich says this castle, Weizsäcker, is small compared to the other castles. Ciel looks at Diedrich and comments that he's a rich boy. The wounded are all treated; Mey-Rin and Tanaka offer to help since they are not injured.
Wolfram and Sieglinde are disguised on their journey to England. Before Ciel leaves, Diedrich tells him to be careful. When the group arrives in London, Sebastian asks Wolfram to refrain from speaking in German because it will draw unwanted attention. The servants leave Sebastian, Ciel, Wolfram, and Sieglinde and proceed to the mansion. When the group returns, the servants all greet them. The entire day passes in light fun along with Agni, Soma, and Elizabeth.
Blue Cult Arc
At Phantomhive Manor, Sebastian gathers Finnian, Baldroy, Mey-Rin, Snake, and Tanaka, and gives each of them instructions, save Tanaka, who is told to remain as is, for the upcoming Halloween celebration. Baldroy, Mey-Rin, and Tanaka share details on the American, Chinese, and Japanese Halloween traditions, respectively, which inspires Sebastian.
On Halloween, Finnian and the other servants, dressed in costumes, greet Ciel, when the latter arrives. Finnian then mingles with the tenants of Phantomhive land, whom the celebration, which features a combination of various Halloweens from around the world, is primarily dedicated to. Later, Finnian and the others set lanterns afloat into a river to end the night.
At Phantomhive Manor, Mey-Rin, Baldroy, and Snake greet who they recognize as Ciel, while Finnian has reservations.
Sometime later, Ciel and Sebastian enter the manor, where the servants greet Ciel. Ciel is confused when Baldroy asks him why he went out "again" in the rain.
At that moment, "Ciel Phantomhive" descends the stairs, to their collective shock. He scolds a dismayed Ciel for getting drenched and assures him that he will never leave his side again and that he has come home. When Finnian states that it is impossible for there to be two Ciels, "Ciel" asserts that he is real. Finnian, shocked, adds that he knew something was wrong when "Ciel" came home and calls him an impostor. Amused, "Ciel" declares that the head of the Phantomhive house, Ciel Phantomhive, is actually he.
To Finnian's and the other servants' disbelief, Sebastian confirms that "Ciel" is the real Ciel Phantomhive. Tanaka soon confirms the same thing and tells them that, fourteen years ago, Rachel Phantomhive gave birth to twins. Pressured by "Ciel" to explain why he deceived them, Ciel calls himself "Ciel's" spare.
Distressed and appalled, Finnian listens to the conversation between Ciel, Sebastian, "Ciel," and Undertaker. He also witnesses Grelle Sutcliff and Othello break into the manor and the subsequent fight which is interrupted with the arrival of Alexis, Edward, Fred Abberline, and multiple Scotland Yard officers.
The policemen proceed to arrest Sebastian and Ciel after they found blood bottles in the manor's basement and Blavat Sky attested that Ciel is "Lord Sirius"—the cult's founder and mastermind behind the Sphere Music Hall murders.
Finnian protests and says that Ciel would never do such a thing, but is held back and cut off by Baldroy who asks Sebastian who will pay their wages from now on. Sebastian tells him that he has to wait for his payment and that he should come and collect it later. Afterward, Sebastian and Ciel are taken away by the police, and Finnian and the other servants can only watch.
Finnian, Baldroy, Mey-Rin, and Snake wait a while until they head out to help Ciel and Sebastian escape from the police carriage and pick them up at the forest's edge later. On the run from Scotland Yard, they drive to London and try to seek shelter at the Funtom Corporation headquarters before going to Pitt's Lark Photographic Studio. Finnian carries Ciel to the studio, and when they arrive, Pitt then helps them to escape through the waterway.
Unfortunately, they were spotted when they entered the studio, and Arthur Randall and a group of policemen follow them down to the sewers. However, before Finnian, the other servants, and Ciel are found and arrested, Lau and Ran-Mao come to their assistance and guide them to one of Lau's opium dens where they are given clothes and food. While they eat, they discuss what to do next.
After extensive researching and planning, it is decided to form pairs and investigate various places potentially connected to the Aurora Society and Undertaker and "Ciel"'s schemes. Finnian is paired with Snake; they must investigate an institution for orphaned children in Norfolk and dismantle any operations that harvest blood.
Ciel, Sebastian, and Lau determine that they must leave London posthaste, as Scotland Yard will soon be at their heels. The group ventures by boat through the River Thames, with the Phantomhive household wearing hair ornaments. When the Scotland Yard's Thames Division demands to see Lau and Ran-Mao's cargo, Lau states that he is delivering "flowers," or girls, to his clients, and bribes them. After the officers permit them to pass, the group arrives at the Reading Railway Station and divides, with Finnian and Snake boarding a train together.
- (To Agni, who tells him to handle the trees with care) "With care, huh? That isn't something I would have understood before coming here, but now it makes perfect sense!"
- (To Agni) "Before, I didn't get to go outside like this all the time, so now every day's a lot of fun! I can come in contact with trees and insects . . . and people too. But, at first, I was frightened. It's really hard for me to touch something without breaking it."
- "The Young Master doesn't give me injections every single day like those other people did. Young Master doesn't make my friends and I kill each other. Nor does he keep me locked up. I love this place. And that's why I made up my mind. I'm going to protect this place."
- "If not for Mister Sebastian, we would never have been able to come here to the manor. I'd never have been able to go outside or . . . feel the rain on my skin like this. No home to return to. No friends. No freedom. Every last thing . . . was given to us by the young master and Mister Sebastian."
- (To Ciel Phantomhive) "If it hadn't been for you, Young Master, I wouldn't be here now! I only knew how to destroy things, but you taught me how to keep them alive. Young Master, you transformed me from Weapon Number 12 to Finnian, the gardener!"
- "I'll bound through this forest... faster than any bullet or hare. Because... I'm 'Finnian'!"
- He appears to be able to speak a little bit of German.
- Finnian's favorite food is Omurice, because Sebastian always decorates it with a little flag. He also likes donuts and deep-fried food, especially deep-fried buns.
- Sebastian is the one who taught him how to read.
- When attempting to join the circus, Ciel uses Finnian's name as his cover, but Ciel states that his occupation is a former pageboy instead of a gardener.
- Ciel is the one who gave Finnian his name. He based it off of the Fenian Cycle, which is a composition of tales and ballads centering on the deeds of the legendary Fionn mac Cumhaill and his war band, the Fianna Éireann. It is part of a series on Celtic mythology.
Out of Universe
- According to the official Kuroshitsuji character popularity poll, Finnian is the tenth most popular character in the series, with 193 votes.
- Yana Toboso gave Finnian green eyes because Baldroy is a "typical" American with blond hair and blue eyes and she did not want them to look the same.
- At some point, she lamented that she did not give Finnian shinier hair.
- Toboso once drew the Phantomhive household celebrating Tanabata and writing their wishes on tanzaku; Finnian's wish was "that everyone stays healthy forever."
