The night before Sieglinde's expected audience with Queen Victoria, Sieglinde and Wolfram talk with Ciel and Sebastian in Phantomhive Manor. Much to Sieglinde's and Wolfram's surprise, Ciel orders her to give the Queen the process to make mustard gas. Wolfram is worried that Sieglinde will be exploited again, as she was by the German military, but Sebastian points out that it is, truly, Sieglinde's choice whether or not she is used or uses others; he adds that Sieglinde is, after all, an extraordinary genius who possesses information that could afford her personal treatment on an international scale. Ciel also states that, because he is Sieglinde's friend, he knows she will never stop studying, but in order to gain new knowledge, she will need a lot of money, which Queen Victoria can provide if Sieglinde works under her. Ciel goes on to say that all Sieglinde has is her intellect and information on mustard gas. Furthermore, he forbids her from speaking about the SuLIN gas. Sieglinde is shocked, and Sebastian explains that mustard gas does not compare to the SuLIN gas in terms of lethality, and thus, if employed in England, countless deaths will result. Sieglinde vows to always keep SuLIN a secret. Ciel reminds her to consider everyone, including him, as an adversary who is trying to use her, and he encourages her to use everyone else in order to obtain the future she desires.
The following day outside Buckingham Palace, Sebastian, Ciel, Sieglinde, and Wolfram meet Charles Grey and Charles Phipps who offer to lead them into the palace. While the other three follow the pair, Sebastian remains by the carriage. Grey asks if he is coming with them, and Sebastian replies that he cannot since he has an errand to run for Ciel. At Ciel's behest, Sebastian heads to the ocean, swims deep in it, and tosses the suitcase of SuLIN samples into a chasm. Afterward, he reunites with Ciel, Sieglinde, and Wolfram outside the palace and assures Ciel that he has done as ordered. Ciel tells him that he is exhausted and wishes to hurry home to sleep. He, then, stares at Sebastian for a while, much to Sebastian's confusion, but Ciel does not explain himself when questioned by him.
The next morning, Sebastian notices that Ciel is agitated while sleeping and is about to wake him, but Ciel jolts awake, simultaneously grabbing Sebastian's wrist. Ciel claims that he is fine, however, and releases him. Sebastian, then, hands him a cup of tea.
One morning, while Ciel is in his office, Sebastian comes in with a letter from Queen Victoria; it explains in detail about a new case involving the Sphere Music Hall that she wants Ciel to investigate.
Abruptly, a greatly dismayed Edward rushes in, shouting Ciel's name. Surprised, Ciel comments that Edward looks pale. Edward, then, reveals that Elizabeth has run away from the Midford Manor, shocking Sebastian and Ciel.
Sebastian advises him to calm down and explain the situation. Once Edward and Ciel are seated, the former informs him about a certain meeting Herman Greenhill introduced him to a month ago; he took Elizabeth along to one of them, at her insistence, and she got her fortune told by Blavat; afterward, she attended the meeting on a regular basis, infatuated with the place, and ultimately stopped coming home.
Edward and Ciel simultaneously state that the meeting is held at the Sphere Music Hall. Edward is surprised that Ciel knows the name. Both Ciel and Sebastian remark on Queen Victoria's "fearsome" powers of observation, and the former explains to Edward that the Queen has requested him to investigate the music hall. When Ciel says that their priority is locating Elizabeth, Edward tells him that he can see Elizabeth if he goes to the music hall: Edward had gone to the meetings a few times and attempted to convince her to return home, but each time, Elizabeth refused, claiming that her "radiance" lies here at the music hall. Ciel declares that they will have to witness it for themselves and orders Sebastian to prepare a carriage for them.
After Ciel, Sebastian, and Edward arrive at the Sphere Music Hall, Edward points out the absence of Elizabeth, Herman, Edgar Redmond, Lawrence Bluewer, and Gregory Violet. Two young woman approach Sebastian, asking if it is his first time here. Sebastian affirms that it is, claiming that he came after hearing how festive the place is, and he inquires about the purpose of the activities there. They say that the place is not formal enough to have an established purpose and that they usually just converse and share advice; fundamentally, they purify themselves so that they can live each day with a positive outlook and that they go there to "pass this radiant time in one another's company." After extolling the place some more, they wave goodbye to Sebastian, and he perceives strange bracelets around their wrists. Ciel says that the environment is unsettling, to which Sebastian agrees. A dismayed Sebastian remarks that desires, like hatred and envy, do not exist on the faces of those gathered there, and because the people there are lacking desire, which he deems essential to the charm of mankind, the place is "unbearably dull."
Edward shows them who Blavat is. Ciel proposes that they get their fortunes told, quipping that Blavat would be no fraud if he can "divine the sorrows" of a demon, to which Sebastian responds that aside from the selfishness of his master, which is his primary concern, his mind is free of worries. After Blavat finishes with a customer, Sebastian steps up and requests for his fortune to be told. Blavat is startled when he sees Sebastian and Ciel, and then he tells Sebastian to sit down, while Ciel notes that the air has shifted.
Sebastian asks for Blavat's needle so that he can prick his fingertip, which is a required procedure for one to get one's fortune told. Blavat maintains that that will not be necessary since Sebastian does not have the divine protection of any star, something he says he can deduce merely by the sight of Sebastian. He yanks Sebastian toward him and whispers in his ear that Sebastian is not human, shocking Sebastian and Ciel.
Afterwards, Blavat laughs, stating that, now, Sebastian and Ciel must be assuming that he is not human either. When Sebastian asks why Blavat thinks he is not human, Blavat asserts that he can tell that much simply by looking; he describes Sebastian as a darkness that "swallows up the radiance of stars shining with all their might"; stars drawn to him will "stray from their orbits to wander the murk for all eternity," because he is like a collapsar. The aroused crowd begin demanding that Sebastian leave immediately. Blavat silences them with a flick of his wrist, and he then urges Sebastian to depart from the place for he has frightened the stars. On cue, two men grab Sebastian; Sebastian secretly steals one of their bracelets as they escort him out of the music hall.
Subsequently, Sebastian is tossed outside. The two men tell him that he is not welcome because he is without the divine protection of a star. After they leave, Sebastian contemplates the anomalies of the place and is shocked when he senses a certain presence. To his delight, he sees a cat. He embraces it, extolling its features, and affirms that if Ciel were not allergic to cats, he would have gladly kept a cat of his own at the Phantomhive Manor. The cat finds the bracelet Sebastian has stolen from one of the men, and he says that the bracelet is not for the cat to eat. He then comments that Ciel will be in the music hall for some time yet; having already anticipated that, he says that he has smoked salmon ready in the carriage and requests that the cat stays with him for a little while.
After the cat leaves him, Sebastian drops by a tavern, where he is approached by a prostitute, who offers to pour his drink for him. Sebastian thanks her, disclosing that he was just rejected by a great beauty, alluding to the cat. She then makes the offer to comfort him, saying that she will even cut him a deal. Sebastian states that he feels like talking to someone and volunteers to treat her with food, to her joy. She looks at the menu, admits that she cannot read, and asks if he can.
Soon after, while the prostitute is eating, Sebastian shows her a bracelet, and she reveals that a friend of hers was wearing a similar one and that a lot of her customers had one, too. She says that she asked her friend why she did not sell it, since she is penniless, and her friend said that there is a room with all "kinds of fun events" that one cannot get into without a bracelet. She remarks that it sounded too good to be true for her, since nothing that tempting is free.
Later, another prostitute joins them, and Sebastian hears a popular song originating from the Sphere Music Hall from them. Subsequently, the three of them head over to the music hall, where Sebastian welcomes Ciel back. Ciel and Edward turn around, and are dumbfounded when they see him with two prostitutes. A flustered Edward scolds Sebastian for having them accompany him, saying that he is still on the job. The women soon leave.
At Ciel's townhouse, Sebastian accommodates Ciel and Edward with tea, while details of the event that transpired at the music hall are relayed to him. When Edward describes the song he heard there as the kind where one would start humming without realizing it, Sebastian sings and dances to a verse, baffling Ciel and Edward. Edward asks if Sebastian had slipped back into the hall, Sebastian responds the negative and is about to explain, but is interrupted by Agni and Soma Asman Kadar, who offer them sandesh.
When Soma asks if the song Sebastian sang is "all the rage" in England, for he hears it sung quite often by kids when he goes out to the market with Agni, Ciel concludes that Sebastian has heard the song from the prostitutes, and Sebastian confesses that that is the case; the woman who sang it to him has heard it from another woman in the same line of work. When Edward questions this, Sebastian explains that literacy in the lower classes of England is still very low, and thus, word of mouth is the most effective method to spread information; furthermore, the best way of making something stick with people by word of mouth is through a song, for words put in a repeating rhythm are much easier to remember than those spoken, which is why hymns and folk songs are used to convey religious teachings and moral lessons.
After both Edward and Ciel make inferences from what Sebastian told them, Sebastian pulls out a bracelet, saying that he took it from one of the men who kicked him out of the music hall and that he was querying people in town about it, when the prostitute from earlier recognized it. He narrates his conversation with her to them, informing them that while the Saturday meetings are open to anyone, there are closed events that only those who have had their fortunes told can attend.
Sebastian accompanies Ciel for a brief visit to Buckingham Palace, where the latter gives a report to Queen Victoria about the Sphere Music Hall. Later, at Ciel's townhouse, he tells Ciel that closed meetings for those with different bracelets are held on different days of the week at the Sphere Music Hall. Bracelet owners can attend the meeting according to their sign on their specific days—Polaris on Mondays and Wednesdays, Vega on Tuesdays, Canopus on Thursdays, and Sirius on Fridays. He mentions that the next day is a Friday, meaning Ciel, who is protected by Sirius, can attend the event. Sebastian suggests attending the meeting as well, but Ciel says that they may know exactly who is protected by Sirius, and is against the idea. Sebastian agrees, and says he will wait outside and that Ciel can summon him if he wishes.
After some time, Sebastian, who is outside the music hall playing with a cat, suddenly realizes that he can barely sense Ciel, and wonders whether he is asleep. He then says that Ciel's attempt at being entrapped is going well, and decides to wait outside until he is summoned. He is approached by Fred Abberline from Scotland Yard, who recognizes him as the Earl Phantomhive's butler. Fred mentions a string of strange corpses showing up; the corpses have no external wounds and seem to be simply asleep; the identified corpses were of a prostitute, a postman, and a shoemaker's assistant; however, a corpse of a peer's daughter soon appeared as well, and thus, Scotland Yard has been working hard to solve the case. To Fred's chagrin, an amused Sebastian comments that the corpses were dismissed as ordinary unnatural deaths, until a member of the privileged classes was found in the same state—that was when Scotland Yard began to deem it an actual case. Fred says that Ciel should cooperate with the Yard if he has any information. Sebastian questions this, wondering whether Arthur Randall would be displeased, to which Fred says that he would take the reprimand if it means closing the case as soon as possible, especially since Ciel's aim and that of the Yard is to protect the people. Sebastian says that he will convey the message to Ciel. Fred tells him to meet with him in person, if he needs to get in touch with him, and then leaves, while Sebastian reflects on the corpses.
Later, he enters a forest, digs up the earth at a certain spot, and finds an abundance of corpses. Sebastian agrees with Fred's previous statement, remarking that the corpses are indeed "far too lovely."
Outside Sphere Music Hall, Sebastian welcomes Ciel. He notices that Ciel is carrying a lot of sweets, and the latter explains that Gregory Violet forced them on him. They climb into a carriage, where Ciel talks about how he fell asleep due to a drug of sorts but emerged unscathed like the others. Sebastian, then, informs Ciel about his encounter with Fred Abberline, the unusual corpses, and how Fred requests for Ciel's cooperation. Ciel finds it amusing that Scotland Yard would be willing to associate with the "evil Earl Phantomhive." Sebastian says that Fred stated that, while their methods may be different, they share the goal of protecting people.
When Ciel says that he needs more information on the corpses, Sebastian pulls out a map, revealing that he discovered eighteen corpses, five of which buried in Epping Forest, east of London; after careful investigation, Sebastian came to the conclusion that the corpses have nothing to common. When Ciel orders Sebastian to collect the bodies and get someone to look at them, Sebastian asks Ciel who he wants to perform the autopsies, thereby reminding Ciel of Undertaker. Ciel, then, decides to have Fred study the corpses.
Suddenly, Sebastian smells blood on Ciel and tears off Ciel's shirt, exposing needle marks, to his and Ciel's horror. Sebastian apologizes for his carelessness and carries him to the manor where Sieglinde and Wolfram reside, to have him treated. When Sebastian knocks on the door, Wolfram, not knowing it is Sebastian, barks at him, but quickly discovers that Sebastian and Ciel are the visitors. Sebastian tells Wolfram that Sieglinde must examine Ciel. At this juncture, Sieglinde emerges, strapped on her new invention: "Arachne Patousa," which are spider legs that enable her to walk. Sebastian informs Sieglinde about the possibility of Ciel being drugged, and she leads them into a room filled with contraptions. Sieglinde discloses that Queen Victoria supplied the items and that she, Grey, and Phipps visit from time to time with cake.
Subsequently, Sieglinde inspects his person and deduces that he is not poisoned. Wolfram has an idea but struggles to convey it in English, and so Sebastian tells him to speak in German. Wolfram, then, makes the conjecture that Ciel became anaemic because his blood was taken from him rather than something being injected in him. He adds that his blood being drawn may be for blood transfusion. Sebastian asserts that the attendees are unwittingly paying for their food and entertainment at special events with their blood.
Ciel states that he knows for certain that the meetings are a menace and that Elizabeth is there. When Sieglinde asks him what he will do, Ciel admits that Elizabeth and the other participants will not listen to reason, and Sebastian agrees, saying that they are all thoroughly under the spell. Ciel decides that to wake them up, he must have decisive proof of the crimes, and tells Sebastian to follow him, determined to expose the music hall's "foul scheme."
In Ciel's townhouse, Fred informs Sebastian and Ciel the corpses died due to severe blood loss. Sebastian and Ciel conclude that the Sphere Music Hall is bleeding their guests to death and that they may also be conducting experiments in blood transfusion. When Fred declares that he will have them immediately arrested, Ciel has Sebastian show Fred the list of people who regularly attend the Sphere Music Hall gatherings—among them are members of the military, the House of Lords, and Scotland Yard, who must be lending financial support to the music hall, so if Fred were to act openly, the individuals in power may not only hush up the investigation, but they may fail to catch the true mastermind, as well. Ciel, then, shoots down Fred's idea to request aid from Queen Victoria, and assures him that he will handle it, as the Queen's Watchdog.
In a carriage parked outside the Sphere Music Hall, Ciel observes that the quickest method would be to infiltrate the inner circle, prompting Sebastian to point out that, as long as Blavat Sky is present, they may be exposed. Ciel, then, suggests bribing the tradesmen who enter and leave the building daily, but admits that Blavat will be the first to hear about it if negotiations fail.
When a couple of tradesmen accidentally drop a box, Nina Hopkins scolds them. Both Sebastian and Ciel are surprised by her appearance.
After Ciel convinces Nina to let him escort her home, Nina explains in detail her association with Blavat and the music hall, and also admits that she never met "those with the names of stars," who are of higher status than the S4. When Ciel requests that she brings Sebastian with her the next time she returns to the music hall, she flatly refuses to, in fear that Sebastian's "outdated grab" will tarnish her reputation. Ciel, then, grants her permission to choose Sebastian's clothes, to Sebastian's dismay.
At Hopkins' Tailor Shop, Nina forces Sebastian to change in and out of several outfits, to Ciel's amusement. Sebastian tells Ciel that he can slip in the music hall without Nina's assistance, but Ciel insists that he accompanies her.
The following week, Sebastian, attired in clothes Nina has deemed fitting, travels with Nina and her assistants to the music hall. At the entrance, they greet the worker, and once they enter, Nina shows Sebastian where the four doors are. Afterward, they part ways, with Sebastian leaving Blavat to her to distract.
After entering the room for special event attendees, Sebastian passes through double doors at the back and arrives at a check-patterned hallway, where he detects a strange smell. The moment he sets foot in the hallway, however, Elizabeth attacks him.
Sebastian and Elizabeth battle, with the former attempting to persuade the latter to go home, but to no avail. He muses that he can "make quick work" of her were she not Ciel's fiancée, and asks her why she does this even though she has always wanted to see Ciel smile, to which she asserts that she does not know. They continue fighting, and Elizabeth shatters the glass window behind Sebastian. In subsequence, Sebastian says that her strength is admirable for a human, and delivers a blow to her chest. As a result, she faints. Sebastian inspects her and is relieved to find that her bones are not broken, remarking that humans are frailer than he expected.
Sebastian, then, leaves her on the ground with his coat and enters a facility where blood transfusion experiments have been carried out. He opens a cabinet and discovers bottles of blood sorted by the names of the stars. He takes some with him, investigates further, and locate the rooms of those said to be embodiments of the four guardian stars. Said four are not in their respective rooms, however, which prompts Sebastian to contemplate the situation: He can easily destroy Sphere Music Hall and kill Blavat and the others, but that would not be enough to quell the fervor of those who frequent the music hall. He, then, decides to report back to Ciel, and picks up Elizabeth.
Before arriving at the townhouse, Sebastian visits Sieglinde and Wolfram at their house and hands an excited Sieglinde the bottles of blood to research.
Outside Ciel's townhouse, Sebastian corrects the way he is holding Elizabeth, in fear that Ciel will scold him, and then goes into where Ciel and Edward are. While Edward monitors an unconscious Elizabeth in a bedroom, Sebastian informs Ciel about his entrusting the blood he obtained from the facility to Sieglinde and adds that he was not able to meet the four with the names of stars. At this juncture, Edward enters the room, questioning why Sebastian came back when he saw evidence of unlawful blood transfusion experiments. Sebastian explains that there is no point in destroying the music hall, as it is merely a symbol, and that the S4 and Blavat are "charismatic celebrities" to the populace of London; therefore, their crushing the music hall and the celebrities can possibly intensify the zeal of the people, and will overall be a disservice. After Edward asks if there is nothing they can do, Sebastian, sensing Elizabeth fleeing the townhouse, comments on the "irksome" nature of human hearts.
A panic-stricken Agni rushes to Sebastian, Ciel, and Edward and informs them of Elizabeth's disappearance. They go up to the bedroom where she was sleeping, and Agni explains that he went to check up on her, but she was gone when he arrived. Ciel deduces that Sebastian knew about her escape; the latter affirms this, insinuating that Ciel would not have thought of anything effective to keep her there, had they detained her; Sphere Music Hall still controls her. While Ciel and Edward discusses Elizabeth, Sebastian considers what Elizabeth has told him before.
The doorbell sounds, and Agni leaves to get the door. They, then, hear a commotion downstairs and discover that Soma and Agni are feeding a multitude of poor children. Sebastian observes that the "street urchins" from other parts of London are also present. Ciel soon comes to a realization and thanks Soma and Agni.
Afterward, Ciel gives Sebastian two weeks to invest in the abandoned theatre across the street from Sphere Music Hall, remodel it into Funtom Music Hall, and make preparations for the grand opening; they also establish the Phantom Five, a group that will rival Sphere Music Hall's Starlight Four, consisting of Soma, Edward, Cheslock, Clayton, and Joanne Harcourt. While Ciel works on recruiting Edward, Sebastian heads to Weston College, disguised as Professor Michaelis, to recruit the others. He visits Joanne first, explains to him the circumstances regarding Edgar, Herman, Lawrence, and Gregory, and asks him to join the Phantom Five; Joanne agrees, since Sebastian helped him in the past. Afterward, Sebastian recruits Cheslock, Clayton, and Soma, as well.
Subsequently, the recruited five assemble at Ciel's office at the London townhouse. When Cheslock questions their choice of Clayton, Sebastian asserts that he can be a star, and modifies his appearance by combing his hair and removing his glasses; they are all impressed with the result. On Ciel's order, Sebastian passes out a folder to each of the five, which details what role they must assume on stage. All except Cheslock is given a description; Cheslock is told to be himself. Sebastian explains, to Cheslock's indignation, that no ordinary person would attend one of the most prestigious public schools in Great Britain with his kind of hair and makeup. When Edward asks how to be "a little naughty and aggressive," Sebastian, on Ciel's command, demonstrates it on Edward by cornering him against the wall, stroking his chin, and dropping a suggestive comment. Sebastian, then, informs a flustered Edward that, according to their recent street surveys, women are favorably disposed to men who are "somewhat forceful." Edward tells Sebastian that he is hesitant about speaking crudely to women, to which Sebastian responds by saying that his "good breeding" is manifest. When Ciel insists that they increase their marketability, Sebastian, in a menacing fashion, maintains that he will train them thoroughly, to the Phantom Five's discomfort. They, then, refine their speech, mannerisms, singing, dancing, and skills through rigorous lessons under Sebastian's guidance.
At night, Sebastian delivers tea to Ciel, and gives his report: Soma is exceptionally talented, for he is not shy and picks up the dancing after being shown the steps only once. Ciel comments in spite of his mental immaturity, Soma is quite capable in almost every area. Sebastian adds that Edward, out of sincere respect for his superiors, is also quickly learning things. After Ciel hands Sebastian a paper which contains all of the new crowd-pleasers he has devised for opening night, he asks him about the blood research; Sebastian replies that he has yet to hear from Sieglinde.
Following the eventful two weeks, the Phantom Five head to Sphere Music Hall to direct its attendees to Funtom Music Hall, while Sebastian stays in the new venue's office with Ciel.
Sebastian complains about the limited span of time Ciel gave him to make preparations, to Ciel's amusement, and adds that establishing an imitation across the street from the original is "terribly cheeky and wicked" of Ciel. Ciel asserts that Funtom Corporation's operation of a theatre is natural, since it is in the entertainment business. He, then, declares that he will school Blavat and the others on "the art of the finest entertainment money can buy," with his Funtom Music Hall.
Afterward, the Phantom Five gather at Ciel's office, where Ciel commends them for their performance. As per Clayton's request, Sebastian returns his glasses to him, while reminding him to remove them before going on stage in the future.
Later, Sebastian informs Ciel that he must make preparations for the Phantomhive earldom's Halloween celebration. Ciel is reluctant to comply, prompting Sebastian to remind him of how important Halloween is to the tenants on Phantomhive land. In consequence, Ciel orders Sebastian to return to Phantomhive Manor and commence the preparations.
At Phantomhive Manor, Sebastian gathers Baldroy, Mey-Rin, Finnian, Snake, and Tanaka, and gives each of them instructions, save Tanaka, who is told to remain as is. Baldroy, Mey-Rin, and Tanaka share details on the American, Chinese, and Japanese Halloween traditions, respectively, which inspires Sebastian.
On Halloween, Sebastian welcomes Ciel home, shows him the extravagantly decorated garden, and has him change into a costume. He, then, explains to Ciel that they have combined various Halloweens from around the world so that their tenants can have quality entertainment.
Subsequently, Sebastian brings Ciel and the other guests to a river, where they are given lanterns. Sebastian has Ciel light everyone's lanterns, which the latter does via a candle. The lanterns are, then, set afloat into the river. Sebastian compares candles and their flame to humans, calling them beautiful. When Ciel advises him to handle them with caution, as, when provoked, they can be formidable, Sebastian assures him that he will strive to keep Ciel's flame alive, for he is a devil of a butler.
At Ciel's office in Funtom Music Hall, Sebastian watches as Ciel tells the Phantom Five that they must perform well.
After a Phantom Five performance, Sebastian accompanies Ciel as the latter comes down the stairs in Funtom Music Hall. They spot Blavat among the crowd, and Ciel greets him.
Ciel and Blavat converse, with the latter deliberately provoking Ciel by mentioning Elizabeth. After Blavat leaves, Ciel angrily breaks a Meissen vase, to which Sebastian responds by saying that the outburst of rage is futile and uncharacteristic of him.
Both the Starlight Four and the Phantom Five continue with their respective shows. At one point, Sebastian reports to Ciel that they have drawn about twenty percent of Sphere's attendees to their music hall.
At Epping Forest, Sebastian and Pitt, a freelance reporter, approach two of Sphere Music Hall's employees, who are in the process of burying a woman. Sebastian reveals that they know that the corpses, which have been popping up around London, are coming from Sphere Music Hall and that Sphere has been using the Starlight Four to attract people and harvest their blood. He adds that Ciel has surmised that Sphere Music Hall constantly needs more blood, and that the true intent of Funtom Music Hall is to steal enough of Sphere's audience so that Sphere would have no choice but draw more blood from their current audience members, and, in turn, more deaths from blood loss would occur. From there, all Sebastian has to do is wait at the burial site and catch Sphere Music Hall in the act of burying their corpses.
Sebastian asserts that, from the beginning, the rivalry between the Starlight Four and the Phantom Five was simply there so that they can mask their true intentions, and admits that none of the Phantom Five members is aware of this. The two men attempt to shoot Sebastian and Pitt, but Sebastian stops the bullets with pieces of cutlery. He, then, appears behind them and kicks the backs of their heads, causing them to fall into the hole with the corpse.
Sebastian suggests that they put their best face forward, as not many get to grace the front page of a newspaper. Both Sebastian and Pitt tell them to "watch the birdie," and the latter snaps a picture of them.
At Phantomhive Manor, Sebastian, Ciel, Soma, and Pitt have convened. Pitt compliments the afternoon tea and pudding, and Sebastian thanks him. Pitt, then, inquires after Tanaka, and Sebastian assures him that he is the same as always. When Pitt attempts to show a photograph of Ciel's family, Ciel snatches it from him and admonishes him, while Sebastian observes.
Afterward, Agni enters the room with Fred, who tells Ciel that he needs to speak to him. Consequently, Sebastian asks Pitt and Soma to leave, and they comply. Once they are gone, Fred shows them the newspaper with Sphere Music Hall in the headlines. Ciel and Sebastian, then, explain the treacherous workings of Sphere Music Hall, and their plan to steal the music hall's source of supply. Fred is appalled that they would indirectly induce the deaths of Sirius individuals, deeming it a "heartless method." Ciel retorts that he, the Aristocrat of Evil, took action when Fred, the "righteous police," could not. When Fred vows to solve the case next time without getting Ciel's hands dirty, an amused Ciel urges him to quickly get promoted.
Later, Sebastian announces that Ciel's carriage is ready. While going down a hallway, Sebastian and Ciel are approached by Agni, who asks Ciel to stop involving Soma in dangerous matters. Ciel states that he will stop putting them both to use, and that he has never considered Soma a friend. While passing by Agni, Sebastian calls him the "very epitome of a butler."
Afterward, Ciel and Sebastian, who gives them plates of food, confront Herman, Edgar, and Lawrence, who are hiding at a pub in Hyde Park. Ciel presses them for the whereabouts of Blavat and Elizabeth and learns that they were not aware that Elizabeth was at Sphere Music Hall in the first place, nor were they aware of the blood transfusions. When Herman mentions Gregory's disappearance, which occurred on the day the Sphere Music Hall scoop was published, Sebastian says that Gregory has Sirius blood, and that it is likely Blavat took him along to continue taking blood from him.
When Ciel asks them if they have an idea where Blavat went, Edgar recalls that Blavat talked about a second music hall being built, and Lawrence declares that it is in Bath. Sebastian and Ciel head out.
At Bath, Sebastian and Ciel ask a couple of residents for the location of a music hall under construction, and they point the way.
Subsequently, Sebastian and Ciel enter the aforementioned music hall, and descend hidden stairs to reach the room where Blavat had taken blood from the men. Sebastian recognizes military elite and prominent members of the House of Lords, and Ciel says that they were on Grey's list.
They find Gregory, and wake him. When questioned by Sebastian, Gregory admits that he did not want his friends to be sad, and, therefore, he went along with Blavat's plans. He also admits, while crying, that he had invited Cheslock and the others to Sphere Music Hall, in hopes that word might eventually reach Ciel, so that Ciel would come and end it all, because he could not bring himself to do it. When Ciel asks him where Blavat is, he says that Blavat has gone back to London, and then faints.
Ciel orders Sebastian to bring Gregory to a hospital immediately, but Grell and Othello arrive; both Grim Reapers assert that Gregory will be fine, since he is not on the soul retrieval list. Othello takes note of Sebastian and gathers samples from Ciel. When Grell tells Sebastian that he should ask them out on a date, Sebastian and Ciel pointedly disregard them.
Othello discloses that the men there suffered from renal failure and that the machines function to replace their thickened blood with fresh blood; in doing so, the men's lifespans were extended. He affirms that entries in the soul retrieval list may be revised every once in a while, especially when there are external factors, such as a demon, interfering with the affairs of humans. He says that while the people who summon demons are usually ordinary, sometimes a brilliant inventor is among them, which would explain the machines. Sebastian and Ciel, then, leave for London to track down Blavat.
Ciel tells Sebastian to inform Fred, Grey, and Phipps about the Bath music hall and Gregory's whereabouts. They puzzle over why Blavat has returned to London, despite the risk of being apprehended. When Ciel mentions Elizabeth, Sebastian reveals that, during their previous encounter, she has said, "I, and only I, simply can't go back over there." While Sebastian prepares the carriage, Ciel muses on Elizabeth's cryptic words. He, then, states that they should return to the townhouse for the time being, assures Ciel that he will report to Fred and continue the investigation, and prepares the carriage.
Later, Ciel and Sebastian arrive at the townhouse, where Sebastian notices that something is amiss. They enter the house, and are astonished to find blood and rubble. They follow the trail of blood, and find Agni at the door, with a multitude of knives in his back. After examining Agni, Sebastian reports to Ciel that he is not breathing, to Ciel's shock. Sebastian is, then, forced to break open the door, where he discovers Soma sobbing.
Sebastian sets Agni down, and states that, for prioritizing Soma's safety and happiness, Agni is "the very epitome of a butler."
When Ciel asks Soma if he is hurt, Soma hits him across the face. After rendering Soma unconscious, Sebastian comments that Soma is understandably confused. After a distraught Ciel composes himself, he asserts that he wants an assessment of the situation. Sebastian deduces that something unexpected must have happened, since five or ten average humans would not have been able to kill Agni, and that Agni's body is still warm, which means that the attack was recent.
Ciel suggests that they do a sweep of the place. They note that Agni must have been topping up the coal in the hearth, and that none of the rooms has been burglarized. Subsequently, they hear a strange noise coming from Ciel's room, and enter it.
To their shock, the words "Who stole the candy from my tummy?" are engraved on the wall. After inferring that the message came from the intruder and that the words appear to be unrelated to Blavat, Sebastian notices that Ciel is deeply agitated. Instead of addressing the issue, Ciel orders Sebastian to have Sieglinde tend to Soma's injuries.
When Sebastian lifts Soma, Ciel spots pieces of a photo falling from his hand. Upon realizing what they are, Ciel asks Sebastian for confirmation that he would never lie to him. Sebastian assures him that he does not tell lies, and Ciel is horrified.
Sebastian and Ciel drop off Soma at Sieglinde's place for her to tend to his injuries. Ciel warns Sieglinde to not carelessly open the door for anyone, even if it is him. Afterward, Sebastian and Ciel decide to head to Phantomhive Manor, as Ciel wants to be "certain" about a matter.
Later, Sebastian and Ciel enter Phantomhive Manor, where Mey-Rin, Baldroy, Finnian, and Snake 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 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.
"Ciel" muses that this is the first time he has actually met Sebastian. He promptly asks him how dare he "do that" to him on "that day". Sebastian affirms "Ciel's" statement that he is "Earl Ciel Phantomhive", to the servants' disbelief.
He looks on as Ciel mutters that he is "the spare" to "Ciel Phantomhive", heir to Earl Phantomhive.
