List of Darker than Black characters

Most of the major characters from Darker than Black.

The following is a list of characters from the Darker than Black anime series and its spin-offs which were created by Bones.

Creation and design

The main characters in Wolf's Rain are heroic, unlike the violent protagonists in Darker than Black; Tensai Okamura wanted the latter's characters to be flawed, in contrast to those in Wolf's Rain. Character designer Yūji Iwahara inspired Okamura to work on Darker than Black, based on his work on the video game Koudelka and its manga version. The narrative was inspired by Japanese dramas, which were explored in two consecutive episodes. Okamura wanted to give his audience comic and dark stories for variety. Actual locations, including Shinjuku and a police station, were photographed to make the series more realistic. Tensai Okamura found early designs unacceptable; until his image of the characters matched Iwahara's, the pictures were redrawn many times. Iwahara found his work on the anime more challenging than his manga, since he had to keep up with staff requests and had little artistic freedom.

Takahiro Komori adapted Iwahara's work for animation, retaining the essence of the original designs and making the animators' work easier; Huang's hat and Yutaka Kouno's and Mayu Ootsuka's clothing were changed. Color designer Nobuko Mizuta was disappointed because much of the series is set at night and the main characters' clothing is generally dark-colored, but she gave the guest characters brightly-colored clothes. Komori said that when he draws female characters, he pays special attention to the line connecting her buttocks and legs. For the OVAs, Iwahara was given the order to draw both characters Hei and Yin sexually appealing. The animation studio wants the viewer focus on appealing action scenes involving Hei. However, there is a glimpse of the weakness of the character, and a tragic fate for Yin, giving the series a suitable culmination.

The Syndicate

At the beginning of the series, The Syndicate (組織, Soshiki) is introduced as a mysterious underground organization with no apparent objective. Its operatives work with both Contractors and Dolls and even have access to M.E. technology in order to erase sightings of their affairs from witnesses' minds. The Syndicate makes extensive use of "word of mouth" communication in relaying both missions and operative status. In the later course of the show, it is revealed that The Syndicate is in fact merely another façade for a global organization in control of PANDORA, that declares to be looking for stabilizing the world order and destroying Hell's Gate.

At the ending of Gemini of the Meteor, a new Syndicate is established consisting of Misaki, Kobayashi, Mao and Madame Oreille after American occupation forces have subdued the old Syndicate.

Hei (黒（ヘイ）, pinyin: Hēi, lit. Black)

Voiced by: Hidenobu Kiuchi (Japanese); Jason Liebrecht (English)

Main article: Hei (Darker than Black)

Codename "Hei", he is an elite contractor with the Messier Code BK-201. Hei has a double persona in the series: as a civilian, he is referred to as Li Shenshun (李舜生（リ・シェンシュン）, Ri Shenshun, pinyin: Lǐ Shùnshēng), a good-natured Chinese exchange student living in an old apartment complex for foreigners and getting by through brief part-time jobs. These are typically related to the current mission he is on. When he is working with the Syndicate, he acts almost exactly as a typical contractor, appearing to be cold and rational. Nonetheless, Hei still demonstrates compassion and sorrow, and these mannerisms are noted as unusual by other contractors. Hei began working with the Syndicate as a child assassin to protect his sister, Bai, in South America during the Heaven's Gate war. Hei's goal is to find her once again. Though he usually calls himself an exchange student, he has never once gone to any University throughout the course of the series, using his title as a student only to gain access to the gate on one occasion.

Yin (銀（イン）, In, pinyin: Yín)

Voiced by: Misato Fukuen (Japanese); Brina Palencia (English)

A member of Hei's team, an emotionless spirit medium known as a "Doll". Her power lies in tracking and observation through direct contact with water. Huang mentions that her "program" is a minimal one, incapable of showing emotion or even allowing her to make decisions for herself; however, she later debunks this by making the decision to keep working with Hei and the others when given the choice of leaving, a possible sign of her recovering her humanity. Yin is of Finnish origin and her real name is Kirsi, which is the Finnish diminutive form of either Kirsikka (meaning "cherry") or Christina. She was once a student of a famed Finnish pianist named Eelis Kastinen (or Kostinen, depending on translation; both are Finnish surnames), who slowly started developing a love interest in her mother. Yin's father died in a plane crash; in the aftermath, Yin's mother was left vulnerable and realized her own love for Kastinen. As they were about to kiss one night, Yin saw them, and ran away in shock. She ran onto the street, and was almost run over by an incoming truck, but was saved when her mother pushed her out of the way, trading her own life in the process. Little, if anything, is known about how Yin became a Doll, but it seems to be linked to her personal tragedy.

Amber says both appear to be similar in regards to their feelings towards Hei and asks her to take care of him. Throughout the course of the series, Yin begins to display emotions and her own will, deciding to follow Hei and remain as his partner. This has been made apparent when she called Hei from the void to come back to her and not leave her alone. In the process, her observation apparition evolved or upgraded, now having a human-like body shaped with her silhouette and is capable of physical touch. Episode 2 of Gaiden reveals that "Izanami" possessed Yin during the events of episode 25, which explains her new abilities. In the OVAs, she confesses her love to Hei during Izanami's awakening but both are split since Hei refuses to lose more important people. The two meet again in the Gemini of the Meteor again to prepare to kill Izanami although her fate is unknown.

Huang (黄（ホァン）, Hwan, pinyin: Huáng, lit. Yellow)

Voiced by: Masaru Ikeda (Japanese); John Swasey (English)

Huang is the leader of Hei's team, and is usually the one giving orders and explaining the mission to the members of the team. Huang is usually very demanding of everyone on the team and often makes clear his distaste of working with Contractors and Dolls. Aside from being the middle man between the Syndicate and Hei's team, Huang will usually show up to provide backup in situations that would have normally contributed to the loss of a team member. Prior to the start of the series, Huang was a police officer known as Kiyoshi Kuno. He met the Contractor Shihoko, who was the only person that he ever loved. However, she seemingly betrayed him, using his love to extract information from him to kill his partner and erase his partner's wife's memory. After the events, the Syndicate appeared and gave him a choice: join the Syndicate, or have his memories of the event erased. Huang chose the former, but the entire ordeal caused Huang's hatred towards Contractors and Dolls. When he met up with Shihoko again on another mission, Huang learned that she did actually love him, as her payment for being a Contractor was to feel human emotions again. Later on, Huang and the rest of his team are cut out of the Syndicate. Huang later dies while helping Hei and the others get to Hell's Gate, exploding his own car that he drives while leading a large group of officers away from them.

His main weapon is a Beretta M 1934 pistol.

"Huang" is the Mandarin Chinese pronunciation of "黄", literally meaning yellow, while the Japanese pronunciation is "ki".

Mao (猫（マオ）, pinyin: Māo, lit. Cat)

Voiced by: Ikuya Sawaki (Japanese); Kent Williams (English)

Mao is a Contractor who has the ability to possess animals, subduing their natural instincts. His Messier code is HM-432. His brain is directly connected to a wireless network which enables him to send and receive information at any time. Mao usually creates diversions for Hei in battle. While on an assignment in Russia following the Pavlichenko family, his human body was destroyed in the explosion that destroyed a laboratory, trapping him in the body of a black cat he was currently possessing. While he completely lost his need to fulfill a payment with the destruction of his body, he must connect periodically with the wireless network or run the risk of having the animal's natural instincts take over. Near the end of the first series, his wireless connection was cut off when he defects from the Syndicate with the rest of his team, resulting in his human consciousness vanishing while in Hell's Gate; however, he manages to reunite with Hei via a backup network under the control of an unknown organization. At the beginning of the second season, he is also in hiding in Russia with Hei and resides in the body of Suoh's pet flying squirrel, Petya.

Pavlichenko family

Pavlichenko siblings during the events of Darker than Black. Shion (left) and Suo (right) with Mao abve Suo.

Suo Pavlichenko (蘇芳・パブリチェンコ, Suō Paburichenko)

Main article: Suo Pavlichenko

Voiced by: Kana Hanazawa (Japanese); Alison Viktorin (English)

A 13-year-old girl who lives in Vladivostok, Russia. In the Gemini of the Meteor story arc, Suoh becomes involved in the war and machinations between the various groups and Contractors, and her life is forever changed when she meets Hei. She also has a younger twin brother, Shion, whom she wants to protect. She is later revealed to have some form of contractor ability when she goes into mental shock. She can manifest an anti-tank rifle (PTRD) from a meteor fragment she wears as a pendant, and can wield the rifle easily despite its heavy weight of the weapon and powerful recoil; however, even though the weapon comes with its own ammunition each time it is created, the wear and tear on it remains, so Suo must maintain it like any other gun. The payment for her power is to fold origami. Her stated goal is to kill all Contractors (though this might have changed due to Hei), and the awakening of her latent powers is referred to by some characters as the "beginning of the end". After meeting her mother, Suoh discovers that she is actually a 'copy' of the original Suoh who died in an explosion many years ago, created by Shion's power. After reuniting with Shion, Suo appears to die after the meteor fragment she is carrying breaks. Later, it is revealed that she has been transported to an alternate world without Contractors (including her brother), where she can live a normal life, with no memory of her previous one.

Shion Pavlichenko (紫苑・パブリチェンコ, Shion Paburichenko)

Voiced by: Hōko Kuwashima (Japanese); Lindsay Seidel (English)

Suoh's younger twin brother, recognized by various organizations as Izanagi, the counterpart to the Izanami entity that has possessed Yin. He was believed to have lost his right eye due to an accident with a falling meteor core fragment during the Tokyo explosion, and that this incident also turned him into a Contractor. It is later revealed that he was in fact born a Contractor, a unique occurrence according to Mao's words, and that the meteorite incident was actually a fake memory he put into his sister's mind. His Contractual payment is to lose the use of his legs every time he uses his power, forcing him to constantly use a wheelchair. His power allows him to create a near-perfect clone of anything, with only one flaw from the original. He leaves behind a clue for Suoh telling her he has left for Japan, which drives her to leave Russia to find him. He is reunited with Suo in Hell's Gate, where he wishes for a world where Suoh can live a normal life before being killed by Izanami.

Dr. Mikhail Pavlichenko (ミハイル・パブリチェンコ博士, Mihairu Paburichenko Hakase)

Voiced by: Katsunosuke Hori (Japanese); Sonny Strait (English)

He also created of the memory eraser. He is believed to have been killed by Hei, but it is later revealed that it had just been another of Shion's copies. He used to be involved with The Syndicate, until they decided to pull the plug and bombed his laboratory, accidentally killing Suoh and Mao in the process. Aware that the current Suo is a copy of the original, he still regards and loves her as the daughter she would have become had she lived, rather than as a replica or replacement for the original. After being reunited with Suoh, Dr. Pavlichenko is mortally wounded while rescuing her from government forces and dies.

Voiced by: Sakiko Tamagawa (Japanese); Anastasia Muñoz (English)

She likes eating greasy food but claims to stay fit due to constantly moving around every day as part of her job. Her father is Superintendent Supervisor Naoyasu Kirihara of the National Police Agency. It appears that she has feelings for Hei, or at least his civilian alias, Li. After the events of Darker than Black and the Darker than Black: Shikoku no Hana manga, she resigns from the section and relocates to the Hachijo-Jima police station. She is then recruited into Section 3 with the alias of Yayoi Ichinose (一ノ瀬弥生, Ichinose Yayoi).

Yūsuke Saitō (斎藤 雄介, Saitō Yūsuke)

Voiced by: Tomoyuki Shimura (Japanese); Christopher Sabat (English)

A subordinate of Kirihara's, who traditionally wears a business suit. Despite being an officer, he seems to have little common sense as he infiltrated a gang operation undercover using his real name.

National Astronomical Observatory of Japan

Its HQ is located at the present day National Astronomical Observatory of Japan, Mitaka Campus, Mitaka. It is affiliated with the Tokyo Metropolitan Police. It monitors and provides information on the actions of the Stars of Contractors in the "false sky".

In the setting of Darker than Black, the MIAC has a black ops division known as Section 3, created 2 years after the attack on the PANDORA institute to eliminate any individual/group with links to the Syndicate. In addition to its mostly Contractor agents, Section 3 has a covert paramilitary commando force armed with small arms, such as the MP5 submachine gun, and tactical gear.

Gorō Kobayashi (小林 吾朗, Kobayashi Gorō)

Voiced by: Ryūzaburō Ōtomo (Japanese); Jason Douglas (English)

Genma Shizume (鎮目 弦馬, Shizume Genma)

Voiced by: Kenta Miyake (Japanese); Newton Pittman (English)

A representative working for the Third Chief Clerk in the 2nd Investigative Division of the Statistics Bureau in the MIAC, as well as a Contractor. Despite his status as a contractor, Genma has a habit of saying some odd things, many of them implying he is a sexual deviant. He is shown to be fairly bumbling as well, as he is the only one who still believes Suo is Shion. His ability allows him to cover his body with whatever material he touches in order to form tank armour, taking from the object until he is sufficiently covered. His armored form enhances the power of his punches and protects him from bullets. His remuneration is to have moxibustion treatment each time his power is used. It is later revealed that he is a double agent for the CIA, and is responsible for Yōko's death. He is killed by Mina who stabs him through the head with her sword.

Mina Hazuki (葉月 水無, Hazuki Mina)

Voiced by: Mitsuki Saiga (Japanese); Kara Edwards (English)

A colleague of Genma's, Mina is a Contractor with the ability to charge any object with energy, which she uses to create potent projectiles from scraps and turn her sword. She also uses retractable wires similar to Hei's. Her remuneration is to passionately kiss a man, which she appears to dislike due to "bad aftertaste"; such is her distaste that with even two mouth washings, she resorts to kissing another woman to remove the taste, though she hints to having an interest in women. She seems to specialize in wetwork, wearing a half-faced balaclava and wielding a wooden katana (which she transforms using her ability). After killing Genma in revenge for Yōko's death, Mina disappears.

Yōko Sawasaki (沢崎 耀子, Sawasaki Yōko)

Voiced by: Kozue Yoshizumi (Japanese); Tia Ballard (English)

A staff member of the MIAC team with Genma and Mina. She usually performs support duties such as driving them around or tapping radio communications. She is captured by Hei, who interrogates her for Yin's location. She is murdered by Genma by putting her through ME Squeezer and probably also by torturing her in the process, as her body is left severely beaten, unlike Pavlichenko's.

Michiru (ミチル)

Voiced by: Marika Hayashi (Japanese); Elise Baughman (English)

An agent of Section 3. She was formerly a housewife to a local restaurant owner named Lebanon, who left him and their son Norio after turning to a Contractor by unknown means. She can manipulate a water source as a weapon and her remuneration is to bake cakes. She loses control of her powers in a battle with Suoh, due to Yin's apparent interference, and dies drowning in a sphere of water.

Secret Intelligence Service

Like its real-life counterpart, its HQ is located at Vauxhall Cross. British Intelligence originally sent three operatives to Japan to retrieve Havoc. There are five known members:

November 11 (ノーベンバー11, Nōbembā Irebun)

Voiced by: Kazuhiko Inoue (Japanese); Troy Baker (English)

MI6's top agent, and a field leader whose civilian alias is Jack Simon. November 11 is charged with investigating BK-201 and his cohorts. November's ability enables him to freeze liquids, including blood in the human body he does not have direct contact with. He is able to shape water into projectiles by freezing it and subsequently hurl them with lethal precision. November 11 has a strong aversion to tobacco, though to his dismay, his remuneration is smoking cigarettes. Through the series, he develops a close professional relationship with Misaki. After he discovers the true motives of the organization he works for he confronts Decade, becoming fatally wounded in the process. He later dies on the street after leaving a voice message on April's phone.

April (エイプリル, Eipuriru)

Voiced by: Takako Honda (Japanese); Nazia Chaudhry (English)

A woman who supports November 11. Her power creates hurricanes which result in downpours, coating everything in water so that November 11 can freeze it. She can also control water more precisely, being able to engulf a person's head in water to drown him or her. Her remuneration is to drink beer, specifically Guinness Stout in the anime. In contrast to November 11, she very much enjoys her remuneration due to her love for alcohol. She dies at the hands of Hei in the first episode of Gemini of the Meteor.

July (ジュライ, Jurai)

Voiced by: Kiyomi Asai (Japanese); Cherami Leigh (English)

A young child most often seen being led around by April. He is a Doll whose observation powers rely on glass as a medium. He considers November and April to be his friends, a fact that initially astonishes Misaki and November as dolls are not supposed to think outside of their programming. April and July frequently visit November 11's roadside site of death with offers of a bouquet or cigarettes and a beer or two. In the third episode of the 2nd season, July assists Suoh by helping her direct her new-found powers against the FSB and the MIAC, and later joins up with Hei's group, although his motivations for joining them remain unclear. After he and Suo are killed by Izanami, they are both seen in the alternate world Shion created, with July being a normal boy instead of a doll.

Decade (ディケイド, Dikeido)

Voiced by: Akio Nojima (Japanese); Sean Hennigan (English)

A member of the Secret Intelligence Service (MI6). November 11's superior. He is killed by November 11 in Episode 22 after November discovers Decade's involvement in the massive effort to destroy Hell's Gate.

August 7 (オーガスト７, Ōgasuto Sebun)

Voiced by: Masaya Matsukaze (Japanese); Gregory Lush (English)

Appearing in the Gemini of the Meteor story arc, August 7 is a Contractor who works at MI6. He has the ability to distort space around himself, allowing him to pull weapons out of thin air, as well as dodge bullets and knives. His remuneration is revealing the secrets of a magic trick. He is also nicknamed "Magician", and he wears a red coat and a black silk top hat. After April's death, August goes after Hei and Suo, but encounters the FSB. He dispatches the FSB agents easily and continues his pursuit, where he has a showdown with Hei. He is defeated and electrocuted by Hei, although he remains barely alive. Genma Shizume apparently finishes him off after Hei and Suoh escape into the sea. In episode 12, he is still alive, appearing in Hell's Gate and asking July to return to MI6 due to the cancellation of their mission, and leaving without the latter when July refused to leave, amused at his display of emotions.

Evening Primrose

An organization promoting equal rights for contractors and their existence to be made public. Contrary to the popular belief, EPR does not intend for Contractors to rise above humanity, but rather seeking a solution for the peaceful coexistence of Contractors and human beings.

Amber (アンバー, Anbā)

Voiced by: Tomoko Kawakami (Japanese); Laura Bailey (English)

The first confirmed Contractor, with her star's Messier code UB-001. She is originally a spy for MI6 with the codename February (フェブラリー, Feburarī) but later defects and joins the Syndicate, adopting "Amber" as her new name. She worked together with Hei and Bai in South America during the "Heaven's War", and founded her own organization, the Evening Primrose at that time. She went missing together with Bai and millions of other people when the Heaven's Gate disappeared, only to reappear later to fight the Syndicate with the rest of the strengthened Evening Primrose. Even after leaving the Syndicate, she chose to keep her codename "Amber," stating that she had grown attached to it. Amber's ability is chronal manipulation, which includes temporal freezing of time and rewinding of events to an unknown degree. Once time has been frozen around her, she can also pull other people out of the frozen time stream, while those still under her ability's effect will no longer detect her presence or movement. Her remuneration is aging backwards. Amagiri has warned her that she cannot use her ability flippantly, saying that she can only pay off her contract to a certain extent. Her overall objective is to destroy the Hell's Gate in a way that doesn't erase every Contractor from existence. Amber has feelings for Hei, in spite of him believing her to be a traitor. She maintains the mysterious Meteor Fragment retrieved from PANDORA's Gate Research Facility in her care in a pouch slung across her shoulder. After showing him all that he would have if he used his power to close off the gate (her, his friends, and his sister), she reveals the true extent of her feelings for him by sacrificing herself so that Hei may pursue, instead, the option of shutting down the particle accelerator that would destroy the gate instead of sacrificing Japan or all Contractors.

Amagiri (雨霧)

Voiced by: Takuya Kirimoto (Japanese); Travis Willingham (English)

A portly, red-haired man whose left eye is frequently shut. His contractor ability enables him to project concussive blasts from his palms. He appears to be Amber's right-hand man, carrying out operations necessary to the Evening Primrose. His remuneration is the consumption of boiled eggs - a fact he does not like due to the cholesterol in them. Surviving the fire in season 1, he gathers the remnants of EPR and retreats into deep jungle. He is later seen rescuing Hei and Yin in Hong Kong after receiving intelligence on the whereabouts of the duo.

Brita (ブリタ, Burita)

Voiced by: Chie Nakamura (Japanese); Jamie Marchi (English)

A blonde-haired woman whose cover was as a secretary in the American embassy in Japan. Her ability is to teleport herself and anyone she is in contact with; however, any clothing is left behind. Brita's remuneration is to kiss other people, which she often combines into one convenient act when teleporting others. She uses her ability to, among other actions, kidnap the researcher Schroeder for the EPR and help Amagiri get to the anti-Gate particle accelerator. Curiously, she seems to have grown accustomed to the inevitable nudity to the point of preference. She is presumed killed in Pandora's attack against "Evening Primrose" "dolls" after being almost burnt to death alongside Amagiri.

Maki (マキ)

Voiced by: Yuko Sanpei (Japanese); Maxey Whitehead (English)

A young boy with heterochromatic irises. Maki's ability allows him to perform a type of spontaneous combustion on objects that he touches with his hands. The explosions can occur remotely as he often prepares handprints before activating his ability. He uses this to cause attacks on the embassies in Tokyo. His remuneration is drinking hot milk. Maki seems to be infatuated with Amber and says he would do anything for her. He attempts to kill Hei out of jealousy, after learning Hei is the "him" that Amber frequently spoke of, convinced that he (Maki) is the only one fit of her love. He is killed by November 11.

Bai (白, pinyin: Bái, lit. White)

Voiced by: Kaori Nazuka, Yuna Fujī (child) (Japanese); Larissa Wolcott (English)

Hei's younger sister. Bai is the Contractor responsible for the disappearance of Heaven's Gate five years prior to the story's setting and had since vanished. The Messier code BK-201 belongs to her star. Bai's abilities are said to be vast, with generating abnormal electricity. In addition to this, she also has the power of molecular reconstruction. Her remuneration is to sleep. At the time of the Heaven's War in South America, Hei was constantly together with Bai during their many operations, acting as a bodyguard of sorts. It was for Bai's sake that Hei joins the Syndicate. When the Heaven's Gate disappeared, Bai's power became Hei's, because—according to Amber—she continues to exist within him by fusion through her molecular reconstruction ability. Hei himself remains oblivious to the fact, until the very end. Her other name is revealed at the end: Xing ("star".)

PANDORA

Physical quantity Alternation Natural Deconstruction Organized Research Agency (PANDORA) is a UN research agency established to investigate Hell's Gate in Tokyo. It is revealed that the Syndicate has sway with the organization and has plans to commit genocide against all Contractors by eliminating Hell's Gate.

Eric Nishijima (エリク・ニシジマ, Eriku Nishijima)

Voiced by: Shinichiro Miki (Japanese); Chuck Huber (English)

A Japanese-American man. He is a high-ranking official within PANDORA. He had influence over Japanese law enforcement over anything related to PANDORA. It is revealed that he is also a high-ranking official within the Syndicate and was placed in charge of destroying Hell's Gate after he had placed a termination for Hei, Mao, Yin and Huang. Hourai later shoots him after Hei destroys the Saturn Ring system. In Shikokku no Hana, his father makes his appearance.

Mina Kandaswamy (ミナ・カンダスワミー, Mina Kandasuwamī)

Voiced by: Sayaka Ohara (Japanese); Carrie Savage (English)

An Indian woman. She is a researcher of PANDORA.

Central Intelligence Agency (CIA)

Following the loss of the dominant superpower position, the CIA strives to restore the United States to her former glory by engaging in various international subvert operations, even as far as going for an all-out invasion on Tokyo at the end of the Season 2.

Nick Hillman (ニック・ヒルマン, Nikku Hiruman)

Voiced by: Shigeru Nakahara (Japanese); Eric Vale (English)

A scientist who Hei meets as he infiltrates PANDORA. Nick and Hei become friends and both have a fascination with the "real sky". Nick turns out to be a contractor and is revealed to have the ability to manipulate electricity, apparently the same as Hei's ability. His remuneration is putting people's shoes on the ground upside-down next to each other. He became close to Hei, thinking that they were both alike, not just in their abilities, but even their dream of wanting to see the real starry sky. He felt that of all the people, he didn't want Hei to know he was a contractor and to get him involved. After he and Hei battle for the artifact known as the "meteor fragment" Nick disappears as soon as the artifact is activated. Apparently, the meteor fragment reacted with Hei and allowed him to make Nick's "dream" come true, which is to have a rocket (which looks very comical) to send both Nick (who became a young boy in his dream) and his sister to space. Nick's ability to have an ambition is a mystery even to himself since contractors shouldn't have emotion.

Corinna Moku (カリーナ・モク, Karīna Moku)

Voiced by: Sayori Ishizuka (Japanese); Kim Matula (English)

A courier who exhibits erratic behavior after infiltrating Pandora. Murdered by Nick.

During a raid on a Dr. Pavlichencko's lab, Goran escapes the huge explosion in the lab and later engages April in a battle in the forest nearby. He is killed when April tricks him into running through raindrops at high speed, which punch holes through his body.

Ilya Sokolov (イリヤ・ソコロフ, Iriya Sokorofu)

Voiced by: Yūji Ueda (Japanese); Christopher Bevins (English)

A contractor with the Russian SVR. His ability is to shut off the brain functions of his victims, causing them to get deprived of oxygen and asphyxiate to death slowly. Ilya is psychotic, sadistic and depraved, and, according to him, he has murdered many women brutally before becoming a Contractor, just to watch them suffer. After he became a contractor, he became more "rational", and started using his ability to deliver a "relaxing" death to his victim. He initially debuts in Hokkaido as he murders an underground doll-trading informant in the toilet of a roadside food outlet. His remuneration is drawing sketches. Although not obliged to do so, Ilya has a tendency to draw rather gruesome images as his payment, particularly of women in death poses with severed limbs and heads. He kidnaps Suoh, Mao and July, intending to hand them over to his superiors, but Hei manages to intercept him. Without his contractor abilities, Hei almost loses to Ilya until he manages to strangle him with his grapple wire. Ironically, Ilya suffers the same sad fate as his past victims -- suffocating to death.

Voiced by: Urara Takano (Japanese); Jennifer Seman (English)

It is she who first brings to light what contractors really are and how they differ from normal humans, this truth being the reason why she started her religion. Her contract is the ability to transform her physical appearance to match a target exactly at the cost of her longevity. Thus, because of her skills, she had been utilized as an infiltrator and assassin. Though young in appearance to her followers, her true form is that of an elderly woman due to extensive use of her contract. She later exhibits emotions unlike a contractor where she truly wished to create a haven for her fellow contractors.

Voiced by: Rumiko Ukai (Japanese); Lydia Mackay (English)

An operative of The Syndicate even longer than Huang, Shihoko is a contractor tasked with the job of infiltrating Alma's organization to gather intel for an eventual assassination.

She had gotten very close to Huang in order to figure out which of the two was working for Alma's organization, leaving Huang with an emotional scar for many years. Her contract allows her to destroy the internal organs of an individual at the cost of regaining her human sensitivity for a short time. The remuneration can put her in a state of psychological shock due to the abrupt swing of emotion. Although she experiences human emotions during her remuneration, she realizes that her feelings for Huang were genuine because even though her contractor emotions came back, the memories she had together with him still made her feel warm. She later commits suicide by jumping in front of a truck, saving Huang from being targeted by the Syndicate.

Shichi aka Claude (Shichi aka Claude)

Voiced by: Tetsuya Iwanaga (Japanese); Johnny Yong Bosch (English)

A contractor who works for the Syndicate who was sent to capture Yin, he appears in Darker Than Black Gaiden. Claude's core ability is the control of people; he can also control people's senses, putting them under illusions. He was even able to trick Hei into thinking he was Amber. His remuneration is that he must eat the petal of a flower. Claude possessed a high degree of irrationality, unlike most other contractors. He does not seem to care about his own safety, but is only intent on causing chaos whenever he can. This may stem from his nihilistic attitude towards the world which he has displayed on several occasions. His main goal is to awaken Izanami, for he believes that she will create a world where Contractors would rule over humans. He manages to capture Yin, and at first his intentions seem to be selling Yin to the highest bidder. However, he calls all the major intelligence agencies at once, causing them to arrive all at the same time and engage in a massive four-way fight. The Chinese are the first to get through to him, and Claude seemingly strikes a deal with them. However, he later calmly throws the money he gains out of the window, and tricks Hei into awakening Izanami. The Chinese agents tackle him for his betrayal, and Claude willingly allows himself to be shot three times in the stomach. He lives long enough to be killed by Izanami.

Reception

The series cast has often be compared with X-Men comics for its handling of supernatural fighters. Anime News Network felt that while the setting was difficult to understand, the narrative and cast were appealing. This was mostly due to the dual personality from Hei who remains as a mystery in the early episodes he comes across with two dual personalities: the assassin Hei and the transfer student Li. The fight scenes were also the subject of praise of the handling of Contractors battles which contrast the lighthearted tones of parts of the narrative more lighthearted. Maxibe Gee from the University of York compared the cast of the anime with the handling noir series or films such as Do Androids Dream of Electric Sheep? and Ghost in the Shell. Although Hei was noted to be similar to noir protagonists, his actions in the first series was noted to be different other heroes from the same genre. The handling of Dolls, most notably Yin, was noted to be a departure from popular series as she becomes one the most important ally to Hei rather than a femme fatale as a result of interacting with Hei across the series, developing a notable humanity in the process.

Though Hei mentors the new lead Suou, Martin found Suou as a more interesting protagonist to the point that he felt Hei was not needed to make sequel appealing. Similar to Martin, another writer from The Fandom Post found Hei as a less appealing character than Suou which made him wonder his fans of the original series were bothered by Hei's relatively less appearances in the sequels. The misrelationship Hei and Suou was noted to be also quite upsetting as a result of have the former's attacks to the latter's family. As a result, he found the OVAs important to explore the character's downfall during his journey with Yin. Nevertheless, the reviewer felt that Hei's concept of an action hero did not change.

The audio of the series earned praise in regards to both Japanese and English actors though Fandom Post recommended the audience to select the later ones when watching the series based on their deliveries. Tomoko Kawakami's performance as Amber was pointed out as "solid" especially since it was the actress' final work before her death, while Jason Liebrecht's Hei was commented to be "a schizophrenic variation" of Syaoran from Tsubasa: Reservoir Chronicle among other appealing English actors. Anime News Network claimed that both Japanese and English voice actors managed to make lipsynch be properly matched regardless of language.

The illustrations and characterizations in Fujiwara's Shikkoku no Hana manga series earned praise by Manga News and Manga Sanctuary for how complex are the cast, most notably Hei and Yin. However, Harverst, was felt lacking in comparison.
