Ran-Mao (藍猫, Ranmao; Chinese Pinyin: Lán-Māo) is Lau's personal assassin.



Ran-Mao is a young woman of Chinese descent with large golden eyes and long jet-black hair with square bangs. Her hair is arranged in thin braids and twin buns shaped like cat ears, and ornamented with a pink peony and a golden tassel on the left bun.

Ran-Mao often wears a short lavender and black cheongsam, which is decorated with dark pink petals, with a dark blue cropped jacket over it. She also wears thick black stockings, black ballet shoes, and gold anklets with bells.

When performing her duties as Lau's personal assassin, Ran-Mao wields two chuí, or meteor hammers; the two chuí are gold, blue, and maroon in color, and adorned with a blue tassel on top. A single swing of the chuí can break pavement.[6]


Ran-Mao is an emotionless, taciturn individual who hardly ever engages in conversation. She is deeply loyal to Lau; she accompanies him wherever he goes and generally acts only when instructed by him.[7] Although she is not related to Lau, he refers to her as his sister, given that they have known each other since they were very young;[8] he once described her as a "pampered child."[9]

Ran-Mao is flirtatious. At Lau's behest or suggestion, she will attempt to seduce others, such as when she flirted with Georg von Siemens at one of Ciel Phantomhive's parties[9] and Baldroy in the sewers below Pitt's Lark Photographic Studio.[10]

Ran-Mao, a highly skilled martial artist, possesses formidable strength and speed.[11] She has no qualms about using violence to extract information.[12] Since she regularly indulges in opium, she has developed a tolerance to sedatives.[13]


Indian Butler Arc

Upon Ciel Phantomhive's and Sebastian Michaelis' arrival at Lau's opium den, Ran-Mao is seen sitting on Lau's lap, along with several other women. She observes in silence at Lau's exchange with the guests.[14]

Later, Lau decides to take Ran-Mao to the curry fair as a treat, which surprises Ciel due to the fact that he could nonchalantly have one of his girls in front of his clients. Lau claims that Ran-Mao is his sister, although they are not related by blood.[15] Throughout the competition, she silently spectates the event, while standing in Lau's arms.[16]

Afterward, Ran-Mao and Lau approach an upset Harold West Jeb and his wife Mina, who are plotting to try another scandalous act. Lau says that while Ciel would not take out the "small fries," he has to exterminate the bad rats infesting his city; thus, he keeps a "cat," referring to Ran-Mao. She swings one of her clubs onto the ground, with enough force to crack the cement. Harold and Mina scream and they are, implicitly, killed by Ran-Mao.[17]

Phantomhive Manor Murders Arc

Ran-Mao and Lau are invited to a party thrown by Ciel Phantomhive. She stands quietly while Lau makes small talk with Arthur Conan Doyle, and when later introduced to Georg von Siemens, she immediately clings to him. Lau apologizes in her place, attributing her bold action to her supposedly pampered nature.[18]

In the midst of the festivities, Ran-Mao and the other guests hear a loud scream from Georg. They rush to his bedroom; inside, they discover, to their unanimous horror, that Georg has been killed.[19] They contemplate the details of the murder, and Lau suggests that Georg's death was a locked room murder. Everyone is, then, asked for his or her alibi. When it is Lau's turn, he says that he and Ran-Mao were drinking in the lounge with Karl Woodley. Ciel is the only one without an alibi, and thus, Arthur is told to watch over him in his confinement. Afterward, Lau and the other guests are escorted to their respective rooms.[20][21]

The next morning, Ran-Mao and the other guests discover the brutal murder of Sebastian Michaelis.[22] Eventually, they resolve to move Sebastian's body to the cellar for the meanwhile, and plan to continue the topic over breakfast.[23]

Later, at the breakfast table, they realize that Patrick Phelps is absent. They head to Ciel's bedroom, where Patrick was assigned to stay in. When they find that the door is locked, Charles Grey swiftly cuts it down. They hurry inside, and discover Patrick's corpse.[24] While everyone else is concentrating on Patrick, Ran-Mao and Lau rummage through Ciel's wardrobe, much to Ciel's annoyance. Soon after, they have dessert at the drawing room, where Ran-Mao silently observes as the other guests discuss the three murders.[25] Ultimately, the group allows Arthur to dictate their actions from that time on, as through deductive reasoning, he is the only one who could not have committed any of the crimes.[26] They decide to investigate Sebastian's body in the cellar, but Lau asks to stay behind to enjoy tea with Ran-Mao.[27] Subsequently, Arthur explains to all the guests that their rooms and belongings must be checked, and they give their consent. Ran-Mao and Mey-Rin search Irene Diaz's room. A distressed Mey-Rin notes that Ran-Mao tends to leave things open after she is finished looking through them. She takes the liberty to sift through Irene's trunks as well, and puts a pair of her undergarments on her head, much to Irene's and Mey-Rin's alarm.[28]

In due course, the group gathers at the drawing room once again. Soon after Lau suggests the existence of a "thirteenth person," Jeremy Rathbone appears.[29] After they verify that Jeremy is not involved in the murders, Jeremy is allowed to lead the investigation.[30] For dinner, the group eats scrumptious steak meat the Phantomhive servants have prepared. Lau presses for the truth behind the incidents, but Jeremy advises them to not be hasty.[31]

In order to catch Patrick's killer, Ran-Mao agrees to be used as a decoy dressed in Ciel's clothes. Upon Jeremy's call, Ran-Mao kicks off the murderer, and Charles Grey steps in to kill it, but Jeremy stops him.[32] They later reveal it to the other occupants of Phantomhive Manor that Patrick's murderer is an African snake, who has aimed to kill Ciel based on his scent; therefore, when Ran-Mao was dressed in Ciel's clothes, it came directly to her. Ran-Mao remarks that his clothes are tight on her. Lau comments that should Ciel have died, they would have been in trouble. She agrees, saying she is glad Ciel is safe and hugs him tightly; Ciel begs her to at least put on proper clothing, and manages to escape from her grasp.[33]

Afterward, Jeremy shows enough evidence supporting the idea that Karl Woodley is the murderer.[34] Subsequently, Karl is detained, and the rest of them celebrate the solving of the case. Ran-Mao and the other guests later leave Ciel's manor.[35]

Luxury Liner Arc

One morning, Ran-Mao accompanies Lau, as he goes to visit Ciel Phantomhive at Phantomhive Manor. She is served food along with Lau, and she leaves with him when he is done discussing the questionable nature of the Karnstein Hospital with Ciel.[36]

Public School Arc

Sebastian Michaelis asks Ran-Mao and Lau to attend Weston College's annual cricket tournament, along with Lau's collection of women, so that said women can distract the other cricket players for Ciel Phantomhive's sake. As a result, Ran-Mao, Lau, and the other women arrive at Weston College on June 4th, the day of the tournament. There, Ran-Mao holds up a betting board while Lau attempts to persuade other spectators of the tournament to place bets on whether Red House or Blue House will win the match.[37][38]

Later, Ran-Mao sits on Lau's lap, and she and the other women flaunt their bare legs, which distracts the Green House players, as planned.[39] After a certain informer reports them to the officials, Ran-Mao, Lau, and the others are forcibly taken away from the venue.[40] Despite this, they are later able to witness Ciel's victory and the birth of the second "Miracle of the Sapphires."[41]

Blue Memory Arc

In November 1889, Ran-Mao and Lau save Ciel and his household when they have to flee from Scotland Yard and are nearly caught in the sewers underneath the Lark Photographic Studio by destroying a part of the tunnels[42] and leading them to one of Lau's opium dens.[43] Later when Ciel and the others have changed clothes, Ran-Mao tells them and Lau that the food is ready.[44]

While Lau and Sebastian discuss how they should proceed as Ciel and his servants are currently wanted, Ran-Mao feeds Lau and tries to get Ciel to eat as well.[45] And when Ciel finally eats and leaves behind a mess, she comments how gross his table manners are.[46]

Blue Revenge Arc

Ran-Mao watches Sebastian and Ciel try to act as employees in the opium den and claps for Sebastian's performance and scolds Ciel for not wanting to wear a dress.[47] She is also present while Lau, Ciel, and Sebastian discuss their plans and bows to Ciel and says "Yes, My Lord" alongside Lau when Sebastian proceeds to do so as usual.[48]

To investigate various places connected to the Aurora Society, Ran-Mao, Lau, and the Phantomhive household form groups of two. 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 Ran-Mao and Mey-Rin boarding a train together.[49]

Ran-Mao and Mey-Rin[50] are sent to North Yorkshire to work at Baron Chris Heathfield's manor as maids under the pretence of being two orphaned sisters named Ran and Mey.[51] There, they are interviewed by Mrs. Abbie and instructed and inspected by Jane and given jobs as a laundry maid (Ran-Mao) and a housemaid (Mey-Rin).[52]

Shortly after their arrival, Chris Heathfield returns and personally greets the new maids.[53] Later, Ran-Mao and Mey-Rin learn that each night Heathfield invites a maid to his bedroom by slipping a note in either their cuffs or collars.[54] Interestingly, chosen maids often leave Heathfield Manor sometime afterward.[55]

Eventually, Ran-Mao is invited to Heathfield's bedroom.[56] At night, she goes there while Mey-Rin waits in their shared bedroom.[57] Chris makes advances toward her, but she rebuffs them by punching him, stating that she punches "lechers." She demands that the missing maids be brought to her. When Chris claims ignorance on the issue, she proceeds to beat him until he yields. Nevertheless, before he can provide information, Jane shoots a tranquilizer dart at Ran-Mao's neck, thereby subduing her. Afterward, Jane drags an unconscious Ran-Mao into a secret basement below the manor and injects sedatives to keep her asleep while her blood is drawn.[58][59][60]

Ran-Mao has Jane in a chokehold.

Later, Mey-Rin discovers Ran-Mao in the basement and battles Jane, who swings her axe at Ran-Mao. Ran-Mao dodges the attack by leaping up from her bed. Then, she binds Jane in a chokehold and informs Mey-Rin that Jane had put her to sleep.[61] Jane asks how Ran-Mao is awake despite the sedatives. Ran-Mao replies that opium is more "potent," and therefore the sedatives pale in comparison.[62]

Jane breaks free from Ran-Mao’s chokehold by flipping her. Afterward, Jane surrenders[63] and, on the condition that they let her go, apprises them of what she knows: She has been hired and paid well by Chris to guard Heathfield Manor so that no one would be aware of the blood-collecting operation in the basement; every now and then, Abbie would escort a group wearing black hoods to the basement; the collected blood would be smuggled out of the manor.[64]

Ran-Mao starts destroying the blood-collecting operation in Heathfield Manor's basement.

To Mey-Rin's and Jane's surprise, Ran-Mao is already in the midst of dismantling the blood-collecting operation in the basement. Mey-Rin exhorts her to be careful not to kill the sleeping maids.[65]

Ran-Mao continues laying waste to the basement. After Annie and the other maids wake up, Jane tells them to head upstairs, and they comply, chiefly due to their fear of Ran-Mao.[66]

Mey-Rin steps out of the storage and informs Ran-Mao that she has disposed of all the blood within. Ran-Mao and Mey-Rin then rejoice in the completion of their mission.[67]

After the maids emerge from the basement in droves, the other maids call Scotland Yard while Jane detains Abbie and Ran-Mao and Mey-Rin detain the house steward.[68]

With Scotland Yard soon arriving, Ran-Mao, Mey-Rin, and Jane depart from the manor. Jane declines Mey-Rin's offer of a referral for employment and declares that she will go somewhere where there are no "troublesome coworkers." Now that their mission is complete, Ran-Mao and Mey-Rin decide to head back to Ciel.[69]




  • Ran-Mao's name translates to "blue cat" in Chinese, and Lau refers to her as his cat.[6]

Out of Universe

  • Yana Toboso and her assistants call her "Ramen's Kid Sister" in accordance with Lau's nickname, "Ramen."[73]
  • In a bonus booklet, Ran-Mao's height was mistakenly given as 154 cm (5'1").[3][5]

    Yes, it's a mistake! I'm sorry, it is indeed my mistake!!!! [...]
    In reality Ran-Mao is about 158cm [5″2′] tall... Otherwise there wouldn't be such a big height difference between her and Ciel! [If she were 154cm tall], that would mean she's as short as Lizzy! (*sweats*) AHHHHH!!"
