The Black Cat manga series features characters created by Kentaro Yabuki. The story follows a young man named Train Heartnet who withdrew from an elite group of assassins called the Chronos Numbers two years earlier and is now a Sweeper, or bounty hunter. Many of the characters are humans with superhuman strength, speed and/or supernatural abilities. Black Cat's anime adaptation features some characters not created by Yabuki, as well as many plot differences.

Train Heartnet (トレイン＝ハートネット, Torein Hātonetto), also known as Black Cat (黒猫, Kuro Neko), is the protagonist and a Sweeper partnered with Sven. Train is a light-hearted, courageous man who is highly skilled with a gun. The 23-year-old's distinguishing features are a choker with a tiny bell attached to it and the XIII tattoo he has on the left side of his chest.^[2]: 26 Two years earlier Train was a Chronos Number, a ruthless assassin and Number XIII of the group. He has a large amount of killing intent that he honed from his days as a Chronos member, and as a result he often has sudden mood swings, going from carefree to serious in an instant, especially when Creed is mentioned. This personality stems from being orphaned at 10 years old after the assassin Zagine Axeloake kills his parents, takes Train in and teaches him how to kill with efficiency.^[ch. 68] Zagine eventually dies and tells Train that he needs to be the strongest in order to survive. After that, Karl took Train in and he became an assassin for Chronos. Having been killing and exposed to death since early childhood, Train becomes very bleak and unsmiling until he leaves Chronos. He eventually meets Saya, a carefree sweeper, who slowly changes Train into a "stray cat" that does not blindly follow orders. He decides not to kill anymore, and after Creed kills Saya, he leaves to become a Sweeper and searches after him.

He wields Hades (ハーディス, Hādisu), a black and gold revolver made out of Orichalcum weighing 2.5 kg, with the numeral XIII engraved into its side and a red tassel attached to its hand grip that stretches out like a leash.^{[2]: 26 [3]: 162} He possesses 20/20 vision^[2]: 26 and is an extremely skilled marksman, able to accurately shoot down bullets from other guns,^[ch. 36] and hit the same place with a number of bullets at exactly the same time. He is ambidextrous, but naturally left-handed; using his left hand increases his speed and accuracy.^[ch. 16] He can also shoot a number of bullets while in the air to accelerate him into a spinning slash, "Black Claw", that leaves four large slash marks. He also uses specialty bullets created by Sven, including the Burst Bullet, which produces an extremely large amount of damage, and bullets that freeze or paralyze opponents. His gun is made out of the strongest metal called Orichalcum, which allows him to use the gun to deflect bullets and guard against other attacks. When his body becomes infected with nanomachines he manages to manipulate them into creating static electricity, allowing him to focus the electricity into the barrel of Hades, turning it into a railgun.^[ch. 111] However, he loses this ability after one last maximum shot in the final fight with Creed.^[ch. 185]

Yabuki chose the name Train because it brings about the image of him freighthopping.^[4] In the original one-shot version, Stray Cat, Train was a famous Sweeper that gave that life up to become a Delivery Man. Additionally, he could use Tao to turn his chi into bullets fired from his pistol with a taijitu symbol on it, or into a blade coming from its barrel.^{[ch. Stray Cat]} Train came in first place in all three of the series' character popularity contests.^[5][6]

Sven Vollfied (スヴェン＝ボルフィード, Suven Borufīdo) is a sweeper and Train's partner. The 30-year-old follows a strict code of chivalry: he is always respectful to women and children and acts very proper.^[2]: 46 He befriends Eve, being the first person to treat her like a human, which causes the two to become very close like a father and daughter relationship. He is often tortured by Train's capricious personality and is usually dragged into trouble and even more debt because of it. Sven is skilled in inventing and making innovative weapons and other various equipment, including bombs and special bullets for Train. Sven's weapon of choice was originally a normal pistol, but after that is destroyed, he invents the Attaché Weapon Case (アタッシュウェポンケース, Atasshu Wepon Kēsu), a suitcase equipped with hidden weaponry inside of it. It contains a built-in machine gun,^[ch. 37] grenade launcher, net launcher,^[ch. 55] an electrical cable, and various other small weapons inside the case.

Before becoming a sweeper, he was an inspector for the International Bureau of Investigations (国際捜査局, Kokusai Sōsa Kyoku), along with his partner, Lloyd Goldwynne. Lloyd possessed an ability called the "Vision Eye" (予見眼（ヴィジョンアイ）, Vijon Ai), which allowed him to see a few seconds into the future.^[ch. 29] Seven years ago, after being attacked by members of a crime family, Sven loses his right eye and Lloyd sacrifices himself to save him.^[ch. 30] A week before his death, Lloyd registered as an organ donor; Sven received one of his eyes and the Vision Eye, although he is not able to use it as well as Lloyd. However, it puts a massive strain on his body so he normally keeps it under an eye patch.^[3]: 26 Sven later evolves it into the "Grasper Eye" (支配眼（グラスパーアイ）, Gurasupā Ai) through rigorous training by having cannonballs fired at him, honing his endurance with the eye to the point where extensive use no longer drains him to the point of total collapse.^[ch. 121] The Grasper Eye allows him to see things in slow motion for about five seconds, allowing him to evade seemingly impossible attacks and barrages, and is less draining than the Vision Eye.^[ch. 142]

The name Sven was taken from a minor character in a blockbuster film Yabuki enjoyed.^[4] In the original one-shot version, Stray Cat, Sven is a Delivery Man instead of a Sweeper and had a beard.^{[ch. Stray Cat]} Sven came in seventh, fourth and third place in the series' three character popularity contests.^[5][6]

Eve (イヴ, Ivu) is a young beautiful girl, who is a genetically cloned and engineered bio-weapon. After being rescued by Train and Sven, she accompanies them on their travels. She is able to use nanotechnology to transform her body into various offensive and defensive weapons and heal any injuries. Initially only able to alter limited parts of her body, she is later able to transform her entire body at will, though it causes a lot of strain on her. She typically turns her arms into blades, hammers and shields,^[ch. 35] turns her hair into fists and microblades able to cut through steel,^{[ch. 63, 101]} turns her own skin into steel, and sprouts wings from her back to fly. The nanomachines in her body also alter her clothing; for changing her appendages or growing wings without ripping them.^[3]: 150 Eve's DNA was taken from the chief scientist responsible for the nanotechnology experiments, Tearju Lunatique, thus the two look identical.^[ch. 108]

She is designed to be the ultimate soldier, being raised to be an emotionless killing machine, not understanding the concept of free choice. She is saved by Sven from the weapons smuggler, Torneo Rudman, and he treats her like a human for the first time in her life. Seemingly unfeeling and more like the machine she was made to be initially, she turned more and more like a human as the series progress due to the time she spent with Train and Sven. She loves reading, and can remember everything in a book after reading it once,^[2]: 112 which also served to build her humanity. Sven initially tries to keep her away from the Sweeper life for her own safety, though she proves that she can fight and he begins to treat her as a partner. She also has a deep sense of compassion and will absolutely not kill no matter what, stemming from guilt she feels for the murders she committed before Sven found her.

Yabuki agonized over choosing her name, looking for one that evoked "purity and innocence."^[4] Eve came in second place in all three of the series' character popularity contests.^[5][6] The character Golden Darkness (or Yami) from Yabuki's later work, To Love Ru, is based on Eve.^[7] They both have the ability to turn parts of their bodies into weapons. Golden Darkness comes from the spaceship Lunatique and her creator is Tearju. In chapter 61 of To Love-Ru, Golden Darkness tries on a black dress similar to the one that Eve wears in the final chapters of Black Cat. In chapter 15 of To Love-Ru Darkness, it is revealed that the character's true name is Eve.

Rinslet Walker (リンスレット＝ウォーカー, Rinsuretto Uōkā) is an infamous thief-for-hire that recruits Train and Sven for a heist, but continues teaming with them afterwards. The 21-year-old works for everyone from mob bosses to the government, this being the reason a bounty is never placed on her.^{[2]: 90 [ch. 2]} Rinslet claims she can steal anything and manipulate any man,^[ch. 2] though she has trouble with Train; she can sucker him into participating in her schemes, but can't get him to follow her plans to the letter. She occasionally provides Train and Sven with targets, so that they can act as distractions while she steals. She treats Eve as a younger sister, much to her own annoyance. Rinslet owns and uses a gun but she is not as skilled at fighting as Train or Sven, she also carries a whip with a heart-shaped tip.^[ch. 35] Rinslet is not cold-hearted and will help others or even destroy what she is hired to steal if the item is dangerous to humanity. She is later forcefully hired by Chronos to act as bait.

Yabuki chose the name Rinslet because it evokes the image of a "silky haired beauty."^[4]

Saya Minatsuki (ミナツキ＝サヤ, Minatsuki Saya) was an accomplished sweeper and close friend of Train. Her involvement with him led to his more human outlook on life and his departure from Chronos. Train denies having had romantic feelings for the 19-year-old, stating he "fell in love... with her way of living. Not bound by anyone or anything... like a stray cat."^{[ch. 31, 61]}

Saya has no memories of her life before the age of ten, due to heavy abuse from her parents. Her first real memory is waking up in hospital and being carried off to a relative's house.^[ch. 184] She constantly wears a yukata because she likes their appearance and thinks it makes her stand out.^[8]: 21 She develops the "Reflect Shot" (リフレクショット, Rifureku Shotto) over the course of five years, allowing her to fire bullets that ricochet off hard surfaces and strike opponents at odd angles and different velocities.^{[9][ch. 117]}

Creed, seeing that Train's personality is changing due to her, confronts Saya and the two fight until she is stabbed while being distracted by kids.^[ch. 117] She does manage to destroy his sword before dying.^[ch. 118] Devastated by her death, Train struggles while whether or not to get revenge on Creed, until settling on taking him in as a Sweeper instead of killing him. Saya's spirit later helps Train defeat the Doctor's Warp World and aim his final shot at Creed.^{[ch. 163, 183]}

Saya's name just popped into Yabuki's head while he was looking at her face.^[4]

Tearju Lunatique (ティアーユ＝ルナティーク, Tiāyu Runatīku) is one of the top authorities in nanotechnology and leader of the group that created Eve.^[ch. 92] Eve's DNA was taken from hers, thus making them look identical.^[ch. 108] She is very bad at household chores and has the ability to trip over nothing. Train, Sven and Eve seek her out after Train is shot with the Lucifer bullet and turned into a child, in hopes she knows how to revert it. Because of the huge cost of a vaccine, she informs him the only other possibility is to mentally concentrate and visualize changing his body, similar to how Eve does it.^[ch. 107] The Apostles seek her out at the same time so Creed can obtain immortality, but she refuses, having resolved to never experiment with humans again.^[ch. 113]

In the anime, Tearju is absent from this part joining much later after the assault on the Apostles, because she had brain damage from an explosion at the time of Eve's creation. She is hospitalized and is shown to react violently to her reflection in the mirror. This is later explained by Tearju as being the result of her having hypnotized herself to react violently toward Eve. She travels with Sven and the others and shares information about Eve and Eden so that they may destroy Eden and save Eve. The Doctor is actually her former partner.

Woodney (ウドニー, Udonī) is an overweight sweeper who imitates Train by dressing in a long black coat, referring to himself as the "Black Cat" and having the number thirteen tattooed on his left arm (albeit it is in Arabic numerals, not Roman, drawn with a marker, and occasionally alternating arms).^{[ch. 44, 45]} He meets with moderate success as a sweeper by using the Black Cat's reputation to intimidate his enemies, but this tactic backfires when he is faced with a powerful criminal.^[ch. 46] After an encounter with the real Train, he gives up imitating him and attempts to become his disciple,^[ch. 46] but Train convinces him he would help more by being an informer to them.^[ch. 47] In the anime, the only main difference in Woodney is that he keeps on following the group, instead of turning into an information broker, and is the cause of some humorous moments.

Tim Vertical (ティム＝バーティカル, Timu Bātikaru) is an orphan whose journalist father was killed by police detective Bouldin for having evidence that the police are making deals with the mafia.^[ch. 64] Before he died he gave Tim the film roll of evidence, causing Bouldin and the mafia to seek the boy out, dead or alive. After being saved by him, Tim asks Train to kill Bouldin so he can have revenge, and Train agrees having been reminded of his own parents' deaths.^[ch. 64] However, Train shoots Bouldin with a fake bullet to teach Tim a lesson.^[ch. 67] Having sent the evidence to the press, Train, Sven and Eve drop Tim off to live with his grandmother. Tim vows to become a journalist like his father and write a story on Train and Sven.^[ch. 67] His last name is only given in the anime.

In the anime, Tim is one of the orphans that Train helps to fight. He is also the new leader of the group of orphans, replacing Leon who is revealed to be their former leader. In his past life, Tim's father was killed the same as in the manga. After the incident, Bouldin and the mafia have been trying to kill Tim and the orphans, and Tim was trying to do the same himself. Following the death of his father Tim, along with Leon and the other orphans, formed a makeshift family to take care of each other. Train and Eve first run into the orphans who are being attacked by a group of men. They find out that the group wants the kids to leave so Train and Eve decided to help them out. When the same men come back for revenge Train defeats them and they leave for good. When the Apostles of the Stars are defeated, Leon goes back to the orphans, but when Eden attacked, it captured Tim. After Eden is defeated Tim is brought back home and reunites with the orphans. At the end of the series Leon, Tim, Layla, and all the kids are working at a restaurant and Leon and Tim talk about what they have been through to get there.

Layla (レイラ, Reira), an anime-only character, is another orphan who lives with Tim and the other children in an abandoned factory. She used to be by herself until she met Tim, and Leon, who then became her new family. After Train refused to help them, Layla explained to Eve their situation. The two girls bonded, and became good friends. Before departing, Layla had her new friend promise her to tell Leon something should Eve meet him. Layla is next seen with her family in the first city approached by Eden. They all manage to not get sucked into the machine except for Tim. Layla, Leon, and the rest of the kids team up with the Sweepers to rescue Eve, and stop Eden. After stopping Eden, the kids open their own bakery, which, according to Leon, was Layla's dream.

Chronos (秘密結社（クロノス）, Kuronosu) is an organization that controls one third of the world's economy,^[ch. 2] and much of the plot revolves around them and their connection to Train, a former member. They have a special group of strong individuals, the Chronos Numbers (時の番人（クロノ・ナンバーズ）, Kurono Nanbāzu), that act as "Erasers" (抹殺者（イレイザー）, Ireizā), or assassins and only follow orders from the Council of Elders that run the organization.^[ch. 20] Each Number have complete mastery of a weapon made of Orichalcum, the strongest metal in the world.^[ch. 26]

Sephiria Arks (セフィリア＝アークス, Sefiria Ākusu), known as Number I, is the commander of the Numbers and is trusted enough by Chronos to be given total control over killing Creed. Sephiria was one of the few members who were "born for Chronos", as she stated that when she was an infant she underwent surgery to enhance her recovery time from injuries.^[ch. 184] Sven once commented that her eyes allowed her to stare into the recesses of one's soul.^[ch. 47] This empathy is her greatest strength, which allows her to utilize her powers of manipulation to their utmost extent. She will do anything to finish her missions and will sacrifice whatever it takes in order to succeed in meeting an objective. However, she does show some inner conflict in her manipulation, even questioning Belze about her actions.^[ch. 47] She controls all of the Chronos Numbers' actions as well as many of the independent operatives in the hunt for Creed with little interference from the Elders.

Despite her gentle looks and young age, her swordsmanship is undisputed. She has such precision and swiftness with her weapon, Christ (クライスト, Kuraisuto, "Ichthus" in the English translation), a saber of unparalleled sharpness, that her strokes produce no sound and her movements leave after-images in her wake. She knows all thirty-six moves of her style, the ultimate being "Mekkai World Destroyer", which completely reduces a target to nothing.^[ch. 170] However, her muscles sustain severe damage in using this technique. Although she loses, she survives her battle with Creed due to Train's timely arrival and her enhanced healing.^{[ch. 173, 184]}

Her personality is drastically changed in the anime. Here, she is much less charismatic, showing little outward emotion, and is generally much more ruthless and aggressive. She is also much less manipulative, preferring to handle things personally and with straightforward planning rather than manipulate others into doing work for Chronos. She initially holds much animosity towards Train for his decision to leave Chronos and tries to kill him on several occasions. At the end of the anime, she and the other four Numbers left take control of Chronos.

Belze Rochefort (ベルゼー＝ロシュフォール, Beruzē Roshufōru), known as Number II, is the vice commander of the Numbers,^[8]: 46 and one of the closest people to Sephiria. He understands that Chronos is a dark and evil organization but also knows that if Chronos is destroyed, the world will fall into chaos. His weapon is an Orichalcum spear named Gungnir (グングニル, Gunguniru). Belze is a cultured man and an accomplished martial artist.^[8]: 46 Creed himself says that even two of his apostles working together have little chance of defeating Belze. Belze holds no ill-will towards Train but hates Creed. He truly respects Sephiria as his superior even though he's several years older than her. After fighting to a draw with Charden Flamberg and Kyoko Kirisaki, Belze is the first to realize just how dangerous the Apostles of the Stars are. He usually takes a back seat to Sephiria and complies with her decisions even though he will express his opinion if he sees a flaw in her plans.

Nizer is one of the first to act in Sephiria's defense when she isn't treated with respect. He holds a personal vendetta against Creed Diskenth for the death of Number X, his old partner Ash, and orders the others to allow him to be the one to kill Creed. Even though he holds a grudge against Creed, Nizer doesn't hunt him down for revenge but to complete his mission as a Number.^[ch. 83] After the destruction of the castle and Beluga's death, Nizer succumbs to a near-fatal wound and enters a coma.^[ch. 87] He recovers but is too injured to partake in the final attack on the Apostles.

Jenos Hazard (ジェノス＝ハザード, Jenosu Hazādo), known as Number VII, is the mid-range attacker of Cerberus.^[11]: 108 A womanizer, that gets violent whenever he sees a woman injured, his attempts at flirting usually fail due to overzealousness.^[ch. 59] Jenos is usually laid-back and energetic and doesn't appear to be serious most of the time, making it difficult for some to believe he's a Chronos assassin. He becomes infatuated with Rinslet, who uses physical violence to avert his flirts, though in the end she begins to warm up to him. In exchange for Rinslet's help in tracking Creed, Jenos becomes her bodyguard. Jenos' weapon is Excelion (エクセリオン, Ekuserion), a glove with indestructible Orichalcum wires attached to its tips, which he uses to tightly grasp or lacerate his opponents or their guns.^[ch. 59] He can also control the sharpness of the wires so they can either cut through stone or catch someone safely.^[ch. 79] Jenos cares about the survival of his teammates just as much as he does completing the mission.

He is the wisest and most experienced of the group, and the lone survivor of the war against the Tao-users 25 years ago. Sephiria states that he has been a Chronos Number longer than most of the members including herself have been alive. He only briefly appears during the final attack on the Apostles, going to investigate another of their hideouts with Belze.^[ch. 184] His weapon is Á Bao A Qu (ア・バオア・クー, A Baoa Kū). In the anime, Mason replaces Creed as the main antagonist alongside the Doctor in the final story arc.

Mason's Orichalcum weapon is a golden suit of armor that covers every inch of his body except his face, and also includes two large swords.

The Apostles of the Stars (星の使徒, Hoshi no Shito) is a revolutionary group led by former Chronos member Creed Diskenth. Their aim is to start a revolution, including overthrowing Chrono's control on the economy. They do not just wish to bring about a world revolution, but they seek revenge against Chronos, each for their own reasons; for example, Shiki and Maro due to the war between the Taoist and Chronos long ago. Some recruits, however, are merely criminals who wish to use their new-found powers to kill for fun. Although Tao has been the primary source of the Apostles' power, Creed also relies on Doctor's investigations in nanomachines to grant him eternal power and elevate him to a god. In the anime, Creed hinted that the Apostles had some partnership with the group Zero Numbers.

Every member of the Apostles of The Stars has the power of Tao (道（タオ）, Tao) and the ability to control their chi or life force to perform supernatural abilities.^[8]: 86 Practitioners possess one of two types of Tao powers by using Soft Chi Kung, a force that accelerates cellular movement through chi; Inner Chi Kung, which manipulates chi inside the body, or Outer Chi Kung, which releases chi outwards.^[8]: 86 Those who possess the potential awaken these powers through the Shinkitou (神氣湯), an elixir only concocted by born Taoists such as Shiki. Another member of the Apostles, Maro, is also from the Forbidden Continent, and together with Shiki, they bear the most traditional Tao powers, such as controlling and summoning bugs (Shiki), using ink marks (Shiki) and controlling gravity (Maro). Other members of the Apostles rely on more "deviant" powers, such as Creed's Imagine Blade, which is a sword that can expand for 80 meters.

The Apostles have a small army of soldiers, armed with all kinds of weaponry and equipped with special armor that can withstand grenades. They are known as the Shooting Star Unit and show great loyalty to Creed and the other Apostles. There is also an experimental squad of cyborg soldiers, the Kiseitai (鬼星隊, lit.

He is the leader of the Apostles of the Stars and Train's former partner before he joined the Chronos Numbers.^{[ch. 14][8]: 202} He tells the group that their only purpose is to destroy Chronos, but he really plans to make himself immortal using nanomachines and rule the world forever by selectivity controlling the human population.^[ch. 113] He is severely warped after being abused by his mother, whom he kills, and the police while living on the streets.^[ch. 184] It is stated that Creed had the abilities to be chosen as Chronos Number XIII, but was deemed too unstable and the position went to Train.^[ch. 27] He greatly admires Train to the point of obsession,^[8]: 202 as he thinks of him as the only person in the world that he can relate to. After Train changes during his meetings with Saya, Creed kills her, and makes it his goal to return Train to his previous lifestyle and have him join the Apostles.^[ch. 14]
