open/close all folders
Pipe Cat Bar, 221st Avenue, Kabukicho
Sherlock Holmes
Voiced by: Katsuyuki Konishi (Japanese), Ian Sinclair (English)
A quiet and non-talkative detective who lives in the building that houses PCB. His passion appears to be rakugo, which he uses to explain his deductions. He's formerly a rakugo performer before he became a detective.
When he does his sketch, Sherlock plays Hatsu and Kuma. Hatsu is the logical character and Kuma is the sarcastic/pessimistic character.
- The Ace: Out from all the six detectives, he's obviously regarded as the best and is able to solve all the cases. He is the only one who manages to get close to Irene Adler and nearly succeeds in getting the USB drive. He's even the top student of his school.
- Adaptational Jerkass: In the original canon, Holmes is an arrogant jerk but he has shown to be quite caring and sympathetic to his clients and Watson. This show's version of Sherlock is very rude to Watson to the point of forcing him to clean his apartment and manipulating him to get what he wants. And unlike in several modern adaptations where Sherlock eventually recognizes and appreciates Watson as his equal and partner, this show's Sherlock treats Watson as a lackey rather than a partner because that role is usually filled by Moriarty and Irene. It only takes 12 episodes for them to become official partners.
- The Alleged Car: Has a green kei car that is troublesome to operate. Watson was able to fix it due to a spark plug issue.
- Bizarre Taste in Food: He has a peculiar taste in food such as eating fried rice with canned fruits and while at Moriarty's birthday party, he eats some sushi with cake frosting dipped in. When he was looking after Yui's daughter he tried to feed her his type of food, leading to her finding it disgusting and throwing the bowl at his head. Seeing him eat bowls of plain rice while naked indicates how much Moriarty's apparent death affected him.
- Catchphrase: "You wanna know?". Happens every time someone asks him how he could have solved the case.
- A Day in the Limelight: The first half of "First Moonlit Night" shows Sherlock's past upon arriving at Kabukicho and meeting with Moriarty for the first time.
- Desperately Looking for a Purpose in Life: Despite being the top of his school, Sherlock grew bored and went to Kabukicho where he discovered rakugo and worked as a part-time bartender in the Pipe Cat Bar. However, his rakugo mentor advises him that his rakugo skills lack originality and tells him to "find his heart". It's only in his first meeting with Moriarty where he finally found his true calling: a detective who uses rakugo for his deduction.
- Foreshadowing: One way to suggest that Sherlock may have experience in conducting rakugo is the presence of a rakugo stage in his apartment.
- The Friend Nobody Likes: Outside of Watson and Moriarty, none of the other Kabukichou detectives particularly like Sherlock; partly because Sherlock tends to show them up when it comes to solving cases but mostly because his anti-social behavior makes him hard to tolerate. This comes to ahead in episode 23 where Sherlock mistakenly becomes the prime suspect of a murder. Watson asks the other detectives to help prove his innocence but they're all reluctant to get involved. Kyogoku ends up putting it bluntly that if it was Watson in the position, they'd have no problem getting involved and while they do eventually help, it does call to question if they would have had Watson not begged.
- Functional Addict: James states that he is addicted to solving cases, even willing to work himself to death to solve it.
- Genius Slob: His apartment is a mess and he relies on Watson to clean it up.
- Heroic BSoD: After Moriarty's Face–Heel Turn and apparent death, Sherlock goes into a massive depressive streak and spends the rest of the episode naked.
- Jerk with a Heart of Gold: He's an asshole to Watson and sometimes treats him like shit. But he seems to have a kind side such as letting James crash into his place because the latter admires his rakugo skills, helps out Lucy in finding the lost money and brings Kyogoku out of his catatonic state after being traumatized by the Jack the Ripper case by putting animal poop on his head.
- After Moriarty is released from prison, Sherlock even buys him a present, much to his (and everyone's) surprise.
- Kick the Morality Pet: While Holmes had his reasoning, using Watson as a pawn to lure out Jack the Ripper ends up crossing the line.
- Large Ham: While doing his rakugo deductions, he becomes a lot more expressive and goofy-looking. Although, it is expected in rakugo since the performer must stay in character.
- Master of Disguise: Part of the myth gag to the Sherlock Holmes franchise. He simply disguises himself as various people in order to get the drop on POIs while staking them out.
- Manipulative Bastard: He and James gaslight Watson in thinking that the latter is Jack the Ripper so they can close in on Kyogoku. He admits he didn't want to do this and lets Watson punch him in the face.
- Manly Tears: He and Watson shed these after reading Moriarty’s final letter in the finale.
- My God, What Have I Done?: His reaction after accidentally shooting Watson in episode 23, as he realizes that what he is doing isn't so different from what Moriarty did a few episodes back. He immediately drops the gun on realizing this.
- Not So Above It All: He cannot compose himself at all when Irene presses her breast up against him.
- The Quiet One: Sherlock doesn't talk much and stays on the side, preferring to examine crime scenes for anything that stands out of place.
- Secret-Keeper: He and Irene are the only ones who know that James Moriarty is James Moran, the mayor's son.
- Sherlock Homage: Based on the novel version of Sherlock. He's very quiet, but uses his acting skills in the form of rakugo, where he uses it to explain his clues and anything else he finds in crime scenes and being a Masterof Disguise. He also wears a modern deerstalker-type hat.
- Sherlock Scan: Of course, he's Sherlock Holmes for nothing if he hadn't used this.
- Slasher Smile: Sherlock tends to do this when he's asked if the person wants to know where his deductions come from.
- Took a Level in Kindness: While Sherlock may be a jerk, he slowly becomes more caring and kinder most especially in the second half. Asides from helping his fellow detectives, he's shown to be empathetic to his clients particularly in "A Lot of Animals" where he's visibly upset that his client was murdered because she wants to help with the case and he feels sorry to the culprits because he, Moriarty and Watson got their favorite band disbanded because one of the bandmates committed murder. However, Moriarty is upset with Sherlock's newfound empathy because according to him, it changed him.
- Tsundere: He helps out his fellow detectives with their problems though he explains that he wants the cases finished.
- Ungrateful Bastard: Sherlock didn't appreciate Watson bailing him from being shot by Cobra at the end of "Why Not Join the Staring-At-Eye-Moles Squad?", mostly because he didn't know that Watson would be able to locate him and take out Cobra.
- What the Hell, Hero?: Watson rightfully calls him out and punches him for manipulating him as bait to lure Kyogoku and identify the real Jack the Ripper. Sherlock apologizes to him for that.
John H. Watson
Voiced by: Yūichi Nakamura (Japanese), Josh Grelle (English)
A young doctor who works in a hospital on the west side of Shinjuku for a year, he's advised to seek out Sherlock Holmes if he wants answers to his problem. Watson later uses his medical experience/knowledge of the medical community to help Sherlock, the police and their allies.
- All-Loving Hero: Even after all of Moriarty's jerkish actions, towards him in particular, Watson simply can't bring himself to hate the boy.
- Big Damn Heroes:
- Saves Sherlock at the end of "Why Not Join the Staring-At-Eye-Moles Squad?" by knocking out Cobra from the back with a vase.
- Saves Mary from being poisoned in "Where is He?" by taking in the injection. Luckily, he didn't get poisoned because his cat beeper stop the needle from going into his chest.
- Butt-Monkey: He's a gullible newcomer to the East Side, and is therefore constantly getting tricked by others or putting his foot in his mouth. As James notes, this makes him a prime target as far as the residents of the east side are concerned.
- The Caretaker: He ends up being one for Sherlock after he moved into his apartment. Then, Sherlock lets him do all the household chores.
- Cosmic Plaything: In "The Thread Where We Talk About Yeast," he admits (in an online forum where he pretends to be an assistant baker) that he's spent his entire life being blamed for everything that goes wrong around him. From being blamed for his parents' divorce by his philandering father, to being too popular with the female staff at a hospital he worked in, which resulted in fights.
- The Heart: He shows a lot of concern to his friends in the East Side regardless of the attitude shown to him. "Eveybody Be There By Eight" really shows him as the one who convinces the rest of the Pipe Cat detectives to help their friend in need.
- He Knows Too Much: Prior to the start of the story six months ago, he found a miniaturized transmitter inside a corpse of a young girl while doing an autopsy and reported about it to his boss. Afterward, his life was threatened, forcing him to flee from the West Side and ask Sherlock's help on his predicament. The young girl happens to be Alexandra Moran.
- I Choose to Stay: After the Jack the Ripper case was resolved with Moran no longer having to go after him, Watson decides to stay in the East Side and be Sherlock's assistant.
- It's All My Fault: Thanks to his experiences in the past, he internalizes everything that goes wrong around him. This hits especially hard in the wake of Moriarty's Face–Heel Turn and apparent death.
- Manly Tears: After he and Sherlock read Moriarty’s final message.
- Morality Pet: To Sherlock. This is very noticeable when Watson moved into the East Side and lived with Sherlock, the latter starts to become more caring and empathic rather than the guy who is cold and obsessed with solving mysteries just for fun. Moriarty even observes that Watson plays the same role as his twin sister, Alex, who keeps her brother in check. It's no surprise that Moriarty wants Watson dead.
- Naïve Newcomer: Since he's new to the East Side, he doesn't know much about the place and residents. James has to guide him out of pity.
- Romantic Wingman: Since Sherlock is too busy protecting Irene, Watson ends up helping Kyogoku confess his feelings to Maki.
- Ship Tease: Like all adaptations, he seems to take a liking on Mary Morstan, who is his future wife in the original canon.
- Undying Loyalty: To Sherlock. Regardless of his initial treatment from him, Watson still cares for him. It reaches to the point in "Everybody Be There By Eight" where Sherlock is accused of killing two prison escapees and Watson still believes he's innocent.
- The Watson: Like almost all the Watsons in the Sherlock Holmes franchise, his presence is maintained in order to ask questions about a case on behalf of the audience. But like his recent counterparts, he's not the flanderized bumbling idiot as initially portrayed in the older adaptations.
- What the Hell, Hero?: Watson ends up slugging Holmes for tricking him into believing Irene had died and that Holmes himself was in danger of dying. Holmes ends up apologizing for the first time for it.
James Moriarty
Voiced by: Seiichirō Yamashita (Japanese), Justin Briner (English)
A young high school student who stays in PCB. He appears to know Sherlock on a personal basis.
- The Ace: Friends with everyone he comes across, skilled in many tasks, and gets high grades in school.
- Adaptation Name Change: His real name turns out to be James Moran in this version, using Moriarty so not to reveal he is the son of the Mayor.
- Adaptational Angst Upgrade: Moriarty from the original canon doesn't have much of a tragic background. In the show, his mother was found dead in her bathtub when he was a little boy and his twin sister was murdered by Jack the Ripper. Then, his father wants him dead. After he was imprisoned for killing the Ripper, despite the fact that he was avenging his sister's death, he's being abused by his prison mates.
- Adaptation Relationship Overhaul: This version of Moriarty seems to be on friendly terms with Sherlock, unlike the novel version who is just a one-shot villain who wants Sherlock dead for dismantling his criminal empire. Their first meeting is even different where James met him when he's a child in a playground, practicing his rakugo. Turn out Moriarty is the one who encouraged Sherlock to take the profession of being a detective and combine his deductions with rakugo.
- Age Lift: Inverted. James Moriarty is a high school kid instead of an old man and he gets along with Sherlock.
- Ambiguous Situation: Him asking Sherlock to "save" him at the end of episode 21. Did he say those words so that Sherlock's grip on his throat would loosen, or was he genuinely asking for help and, deep down, had been wishing for Sherlock to "save" him all through these years? The last episode reveals it to be the latter case.
- Angsty Surviving Twin: He lost his twin sister in the hands of Jack the Ripper. He feels responsible for her death because he let her go to the East Side alone while wearing his clothes. In the 11th episode it is revealed that the killer was sent to kill him, but mistook his sister (who was wearing his clothes) for him and killed Alex instead. Which means his sister ended up dying in his place. James takes it as well as one would expect.
- Beware the Nice Ones: He's a friendly guy but he definitely wants his sister's killer to pay for what they had done to her.
- Big Bad Friend: After leaving prison, he slowly becomes the enemy to the Pipe Cat detectives, particularly to Sherlock, because he just wants to have fun.
- Big Damn Heroes: In the OVA, he saves the Kabukicho Irregulars from a bunch of street gangsters. This is the first time meeting with these kids.
- Creepy Child: When Sherlock met him as a child, he noticed that there was a dead butterfly beside him. This becomes more apparent in "Moriarty Savors" where James kills his mother by tossing a plugged-in hairdryer into her bathtub and watches in awe as she got electrocuted.
- A Day in the Limelight: The second half of "First Moonlit Night" shows his past before he arrives to Kabukicho.
- Dissonant Serenity:
- When the crazed fans of Momotaros (the band that Sherlock and Moriarty investigated) burned themselves to death, Moriarty just watches them in a very calm and disturbing manner, in contrast to Sherlock who is horrified to what he saw.
- He's also like this as a child. He went outside his house and stared at the fish that died after being struck by lightning. Then, he decided to test this on his mother who was taking a bath. The most disturbing part? He just stood there and watched her die while smiling in tears.
- Dramatic Irony:
- Despite Moriarty wanting Sherlock to "break his teapot" like he did, Sherlock reveals he probably would have long ago if he had not met Moriarty in the first place, who made him see the world in a better light. Moriarty does not take this well.
- Likewise, despite wanting to kill his sister, Carlyle tells him that Alex nearly accepted that she won't live long due to her illness until she learned that James killed their mother. So, she tries to stay alive in order to watch over her brother until Jack the Ripper killed her. Then, Moriarty realizes that he is the reason Alice wanted to live.
- Engineered Heroics: Heavily implied that his new "Hero Detective" persona is fake and he is behind many of the cases he helps solve.
- Evil All Along: It takes nineteen episodes for it to be completely confirmed, but considering the fact that he is named after Sherlock's archnemesis in the actual canon, this was inevitable.
- Foil: He is one to Sherlock. Both of them have an ambiguous mental disorder (which is more severe in Moriarty's case) and share a fascination for mystery-solving. However, while Sherlock Took a Level in Kindness and started becoming compassionate after meeting Watson (who later becomes his Morality Pet), Moriarty Took a Level in Jerkass and went off the rails after losing his sister Alex . Both of these events happened right at the start of the story, marking the start of Sherlock's Character Development and, at the same time, Moriarty's Start of Darkness .
- Friend to All Children: He seems to be the ringleader of Kabukicho Irregulars as he knows them personally.
- Foreshadowing:
- There are a lot of hints that James is Mayor Moran's son such as being acquainted with Irene where James calls her, "sensei". Irene used to work as a tutor for the Moran children and he and Alexandra looked very much alike because they're twins. When she went to the East Side, Alex wore James' clothes which unfortunately led to her murder by Jack the Ripper.
- Considering that he's named after the great detective's archnemesis, there are hints of his spiral to villainy such as crushing butterflies since he was very young which shows that he's not a normal child, and being excited whenever something bad happens in the previous cases. The opening itself even explicitly hints Moriarty's dark nature.
- The Gadfly: He likes to tease Sherlock every once in a while, much to Sherlock's annoyance.
- He's Back!: After the 10 month time skip in "Michel and the Stupid Book", he returns to the PCB.
- I Let Gwen Stacy Die: He feels guilty that he's indirectly responsible for Alex's death because he stayed behind in the mansion while Alex, who was wearing his clothes, went to the East Side all by herself. Episode 11's reveal has probably just worsened this guilt . Averted, as it is revealed later that what he felt after she was killed was a completely different feeling.
- I Never Told You My Name: Watson suspects that he is connected to Jack after Irene's death. The only people who knew where she was were Irene, Sherlock, and himself, yet for some reason Moriarty was there right after she was stabbed. Sherlock told Watson later that he's responsible for filling Moriarty in on the details.
- Later he reveals he knows the names of the crazy fangirls who tried to kill them and Sherlock finds him in the background of one of their pictures.
- Intergenerational Friendship: He's been friends with the Pipe Cat Detectives who are mostly adults and he's very close to Sherlock, who is older than him.
- It Amused Me: His motive for the cases of the escaped prison mates and their suicides? He just wants to have fun with Sherlock in solving all the cases that he had set up.
- Kick the Dog: He becomes more cold-hearted and deceptive after he got out of prison, to the point of kidnapping Lucy and forcing Mary to kill Watson in exchange for her sister's freedom because he finds Watson a distraction just like Alex.
- The Man Behind the Man: He's responsible for the mysterious suicide cases of several prison escapees all because he wants to have fun with Sherlock.
- Mind Control: It is all but stated that he is using some form of mind control on the suicide cases. It seems to be activated when he or the police state the targets' full name, or Sherlock asks "Where's Moriarty?", after which they say aloud a numerical code and kill themselves. Moriarty admits this in "The Curtain Rises on the Grand Guignol".
- Missing Mom: His mom was found dead in the bathtub when he was very young. "Moriarty Savors" reveals that he was the one who killed her.
- Mr. Exposition: He usually provides information to Watson regarding Kabukicho and its inhabitants.
- Nice Guy: Well he did help feed the hungry kids... by taking Watson's cash. Later on, he gives advice to Watson regarding Kabukicho. Doesn't stop him from becoming a villain, though.
- Noodle Incident: Whatever happened in the prison between him and the other inmates. Moriarty was the one who was being beaten at the start, how did he become a perpetrator?
- Related in the Adaptation: In the original canon, Moriarty is Moran's boss. In the show, Moriarty is Moran's son whose real name is James Moran.
- Roaring Rampage of Revenge: The reason he's staying in Kabukicho is that he wants to get revenge on Jack the Ripper for killing his twin sister, Alexandra. When he finally catches up with the Ripper, James beats her with a tire iron and slashes her throat when the latter taunts him about eating his sister's womb.
- Self-Made Orphan: Killed his own mother (unintentionally) when he was a kid. As of "Moriarty Savors", he has also killed his father.
- Slowly Slipping Into Evil: He seems to have become darker after he killed Jack the Ripper and returned from prison. It is also heavily implied he is behind the 7th Prison Break Out and the suicide cases of the escaped inmates after they are caught, which is later shown to be true in "The Curtain Rises on the Grand Guignol". At this point, he has completely slipped into evil.
- Start of Darkness: While he wasn't a mentally stable character to begin with, Alex's death and his subsequent murder of Jack the Ripper is what kick-starts his ultimate downward spiral towards villainy.
- Stepford Smiler: He's shown to be very cheerful towards his friends but deep down, he doesn't want anyone to see how sad his life is. Becomes more prominent in "First Moonlit Night" when Watson, Sherlock and Mrs. Hudson come to visit him in prison. He greets them with a smile and then jokes saying that he was worried they'd forgotten him. However, later in the episode, when Isshiki is treating his wounds, he breaks down into tears as he admits that he feels lonely.
- It is also a mask which he used to hide his psychotic side. After the reveal in "Moriarty Savors", he appears to be a mixture of both Type B and Type C.
- Teen Genius: He gets very good grades at school and he is based on the villain who was able to match wits with Sherlock.
- Took a Level in Jerkass: After being released from the prison, he becomes a lot colder to everyone from the PCB.
- Tragic Villain: A downplayed example. He was a very messed up kid, but he never was an evil person right from the beginning. With Alex's help, he was able to live a normal life, but after her death, he started developing a murderous intent towards her killer. Despite this, there was hope for him, but after his murder of Jack, that hope was totally crushed, just like Sherlock says. Another important fact to consider is that he was just 16 years old. Had he been provided some help, he probably wouldn't have turned evil. And for all his talk about wanting to have been the "one who killed Alex", Carlyle's side of the story reveals that he did care about her, though he himself could not realize it.
- Troubling Unchildlike Behavior: He shows some signs of it when he was a child, specifically when he killed his mother because he wants to experiment just like the fish that got electrocuted by a lightning bolt. After meeting Sherlock for the first time, the latter noticed a dead butterfly in pieces where he'd been.
- Would Hit a Girl: At the end of "Moriarty Savors", Sherlock infiltrates the Moran estate and comes across the corpses of the Moran estate staff, including the maids, killed by James. He later admits he killed his mother and wished he was the one to kill his sister.

The elephant on her building also seems to act as a signal to the others for when a case is closed.
- Open-Minded Parent: In the OVA, it's revealed that her son transitioned after going to Thailand where he, as Sherlock puts, was reborn. When Mrs. Hudson finally meets her daughter, she immediately embraces her showing that she accepts her newfound identity.

- Trademark Favorite Food: Strawberries. Apparently, Sherlock uses this as bait to get him because Watson told him that Pipe is trying to eat his strawberry cake during Moriarty's birthday party. And as Truth in Television, strawberries are non-toxic to cats.

- Stockholm Syndrome: Sort of. Even though Cathy ran away with all of his money and the detectives already pointed out that he got conned, Dilan still believes that they're engaged. He grows out of it after the case is closed and he goes back to his old job.

- Canon Foreigner: He only exists in the show.
- Chubby Chaser: He clearly has a crush on the plump woman Maki who is a regular at the Pipe Cat.

- A Day in the Limelight: "Michel and the Stupid Book" focuses on his past and his efforts to save his estranged daughter from a false murder accusation.
- Canon Foreigner: Though Doyle was fond of using the surname "Belmont", no one coming close to Michel's description appears in any of his works, though one could consider him a Truer to the Text interpetation of Lestrade (who appears in this series as an awkward and nerdy Salaryman police officer).
- Dark and Troubled Past: Japanese story material indicates that he's a known TMPD officer who was forced to leave after his name was dragged into an unknown scandal. Even though he was found to not be a corrupt cop, his reputation went down the drain. In "Michel and the Stupid Book", it is revealed that his family was terrorized by the yakuza because of his gambling debts, resulting in his daughter getting injured.
- "Eureka!" Moment: He's the second detective next to Mary who realizes the true identity of Jack the Ripper after listening to Sherlock's rakugo summation on Kyogoku's motive of stealing the USB drive. He even left in a hurry without listening to the rest because he saw that the culprit had already left the bar.
- The Gambling Addict: He keeps going to casinos to gamble, leading to his connection to the yakuza just to pay off his debts.

Futaro
Voiced by: Ryōko Shiraishi (Japanese), Alison Viktorin (English)

- Walking Spoiler: Talking about Kita in any way would eventually reveal he's Kitaro.
Saori
Voiced by: Arisa Date

A known actor and singer who Kyogoku admires.
- Gratuitous English: Tends to drop them in the Japanese version. Averted in the various dubs.
- I Never Told You My Name: How Sherlock traps B-Zo as an accomplice to frame Pu.

- Noodle Incident: He's having problems with loan sharks, especially with his very own relative.
- Theme Naming: His name is based on space terms in Japanese.

- Gratuitous Rap: Whenever he introduces himself, he decides to break down into impromptu rap sessions.
- Karma Houdini: Sugimoto decides to end his life by committing suicide by jumping from the building after getting high rather than conduct yubitsume to be publicly humiliated.
- Large Ham: He is first introduced chopping at the air in broad daylight, because he hamtastically declares he is "cutting the sun". Then he starts rapping.
- Smug Snake: He's decent at making money for his gang, but certainly not the criminal mastermind he likes to believe he is.

Voiced by: Maaya Sakamoto (Japanese), Caitlin Glass (English)
A former tutor who used to work for Mayor Moran and is Godfrey Norton's girlfriend. She's actually an acquaintance of Sherlock.
- Adaptational Badass: As usual for modern adaptations of the character. Irene's career and reputation have expanded from a 'mere' theatre actress to educational expert, financial analyst, violinist, upper class tutor, and more, not even speaking of her skill regarding criminal activities.
- Adaptational Villainy: Like most Sherlock Holmes adaptations, Adler is upgraded from a clever woman trying to protect her new family from a paranoid Jerkass, to an Anti-Villain positioned as Holmes' rival.
- The Bus Came Back: She returns to Kabukicho in "The Thread Where We Talk About Yeast" after learning what had happened to Moriarty and Sherlock.
- But Now I Must Go: After the Ripper case was resolved, Irene goes to New York where Norton is. Before that, she thanks Sherlock for helping her with the case.
- Femme Fatale: She's speculated by the detectives as having had an affair with Mayor Moran and then stealing a USB drive which possibly contains revenge porn as means to blackmail him.

- Hidden Heart of Gold: Despite her manipulative nature, she actually cares about the people close to her.

- Mythology Gag: Her relationship with Gregory harkens back to the original novels where Irene is introduced to be married to him.
- It's Personal:
- The reason for taking up the Milverton case is because she sees herself in his daughter, Emiri, who doesn't have a father figure. Likewise, her former co-star, Agatha, also got caught up in Milverton's blackmail and Irene does her best to help her, even if it means covering up her crime of killing Milverton as revenge.
- It turns out stealing the USB drive is related to Alexandra Moran's death at the hands of Jack the Ripper and how Moran fits in all of this. And since Alex was her former student, she's very determined to find out her killer's identity despite her own life being in danger.
- Secret-Keeper: She and Sherlock are the only ones who know that James Moriarty is James Moran, the mayor's son. It even helps that she's his tutor.
- The Sixth Ranger: She ends up managing the Pipe Cat Bar and volunteers in the case of Milverton after Sherlock backs out due to lack of interest.
- Too Clever by Half: She outclasses all the detectives including Sherlock. However, she nearly loses the USB drive when she's walking on the street alone and is nearly held-up by a hooded man who demands the drive before Sherlock calls him out. Luckily, the drive wasn't stolen and is in Sherlock's possession, who switches the real drive given to Mycroft with a fake one.

- Did Not Think This Through: He controls people by collecting blackmail material on them. He doesn't seem to realize said blackmail material remaining secret is the sole reason his victims don't just kill him. Guess what happens to him after he publishes Agatha's material and she has nothing left to lose.
- Hate Sink: There is absolutely nothing likable about this guy. He is a Smug Snake who blackmails people for payment (both in cash and sex) then releases the material if they are merely 5 seconds late with payment, uses his blackmail empire to traffic child Sex Slave, has no fear from the police since he has blackmail material on the higher ups, and wanted to steal the custody of his own child away from his sick wife just so he could sell said daughter to a pedophile. After he is killed, Sherlock just tells Lestrade to label it a cold case as there are WAY too many suspects that understandably wanted him dead.
- Jerkass: He is the king of blackmailers who possesses dirty secrets of celebrities and high-profile individuals. He even threatens his wife to give custody of their daughter, Emiri. But it's clear he has no regard for Emiri and doesn't care about her as he plans to sell her as a child prostitute.

- The Bus Came Back: After being briefly shown as compassionately treating Moriarty in the prison infirmary, and said to have been beaten up by Albert and his goons for that, so badly that he was released early from prison to be treated at a real hospital, you'd think you'll never hear about him again. It's just that he was mentioned as being in prison for attempting to poison his wife...
- The Man Behind the Man: He's apparently behind the scam as the "CEO", Kimiko Gosyogawa, is nothing but his lackey who is loyal to him.
- Sadist: He really takes pleasure in poisoning people and laughs maniacally when he poisons one of the members who tried to leave.
- Villain with Good Publicity: A known public speaker who has plans to commit a mass poisoning scenario in Tokyo.

- Dark and Troubled Past: He and his mom were abandoned for another family. This pissed him off and fueled his plot to kidnap Ranpo.
- They Look Just Like Everyone Else!: Harukiyo's a nice and upstanding guy in the memorial hospital he works at. This works that he wasn't considered a suspect by the hospital staff.
- Walking Spoiler: It's hard to explain things in his episode once you know his full backstory.
- What You Are in the Dark: Fuyuto had to negotiate with him to surrender Ranpo and give himself up to the TMPD before he could be arrested for potentially harming the boy. He later agrees to give up after Fuyuto tries to make him remember that they need to fulfill their friend's promise to create a better hospital for everyone, regardless of where they're from.
- Would Hurt a Child: Through making threats and kidnapping Ranpo for a ransom demand.

- Even Evil Has Standards: Harry dotes on his grandmother from when he was young, that when she shows up, he uses a tazer to keep his guard from trying to attack her.
- Villain with Good Publicity: Known to be a philanthropist for visiting prisons and talking to prisoners. Probably met Moriarty that way, explaining why he suicides later.

- Would Hurt a Child: He kidnapped Lychee as a human shield after Sasuke warns him that he can't team up with him because they're getting old and age is catching up, not to mention that he's already married.
Crazed Momotaros Fans
- All There in the Manual: The trio were named by Moriarty in their confrontation in the fire escape staircase.
- Disproportionate Retribution: The girls wanted to get Sherlock, Watson and Moriarty killed by other fans, or failing that by their own hand, due to unmasking Phesant as a killer.

Though that last one is heavily implied to have been caused by Mind Control
- Samus Is a Girl: Sherlock and Watson are shocked to find out the Momotaro impostors are high school girls.
Shinjuku City Government
Sebastian Moran
Voiced by: Naomi Kusumi (Japanese), Christopher Sabat (English)
The Mayor of Shinjuku Ward. His daughter was one of Jack the Ripper's victims.
- Adaptational Wimp: In the original stories, Moran was a soldier-turned-assassin with an almost legendary career, and a Cold Sniper skilled enough that Holmes spent years trying to stay out of rifle range of him. Here, he's a mayor who slowly goes through a Humiliation Conga in the second half of the show, culminating in his murder at the hands of his son, who taunts Moran while he begs for mercy.
- Crocodile Tears: While being interviewed by the press, he pretends to be mourning for his dead daughter; though it's very obvious that he's faking it. He does it again when James got arrested for killing Jack the Ripper.
- Large and in Charge: Has notably thicker proportions compared to the average person, and is the one who runs the area.
- The Man Behind the Man: "Jack the Ripper" mentions that he recruited Jack to assassinate James. "Moriarty Savors" reveal that he had a good reason for wanting his son dead.
- Parental Betrayal: Given to his reaction on Alex's death, he doesn't care about her. He also ordered Jack the Ripper to kill James. When James learns about this, he's completely shocked.
- Related in the Adaptation: In the original canon, Moran is Moriarty's assistant and sniper. In the show, he and Moriarty are father and son respectively.
- Offing the Offspring: Jack reveals that she was paid by Moran to kill his son James but accidentally killed Alex when she went off wearing James' clothes. The real reason is that James killed Cecilia when he was young and Moran was understandably disturbed about it.
Mycroft Holmes
Voiced by: Ryōtarō Okiayu (Japanese), J. Michael Tatum (English)
Sherlock's older brother who works as Mayor Moran's secretary.
- Adaptational Attractiveness: Mycroft in the books is a bit obese but in this show, he's skinny just like his brother.
- Aloof Big Brother: There's some animosity between him and Sherlock. But he knows that the case regarding Irene Adler can stir some interest in his little brother and even offers the rare rakugo trading card as the grand prize.
- Big Brother Instinct: In "See You in Kabukichou", it turns out that Mycroft really cares for Sherlock and wants him to call him "brother" which would explain why he's angry at Watson for calling him "brother".
- Knight Templar Big Brother: Played for Laughs as pointed out by Sherlock in "See You in Kabukichou" where he said his brother has a huge brother complex on him which would explain all the hidden cameras in his apartment. In the OVA, it extends to him tracking Sherlock's movements and having a collection of his childhood valuables. Every time goes home he would watch over his little brother through his hidden cameras.
- My Sister Is Off-Limits: He doesn't like how Watson is close to Sherlock. In the OVA, he prepares a stack of voodoo dolls of Watson where he directs his anger on them whenever Watson shows up on his camera feeds.
- Stoic Spectacles: He's very calm and collected and rarely shows much of his emotions.
Kabukicho Irregulars
General
A group of rowdy children who spend their days after school running cons and robbing hapless people blind. While their tentative leader is Yoshio, they all look up to James Moriarty as a role model.

- Baker Street Regular: Like in the original stories, Holmes frequently hires them to supply information or other kinds of help.
- Fatal Flaw: Greed, naturally. As young, headstrong children, they occasionally rob from people they should have left alone, such as Yakuza thugs.
- Free-Range Children: It's unclear if they're orphans or if their parents are present in their lives, let alone allowing them to walk around in a place like Kabukicho and do illegal activities there such as stealing.
- Troubling Unchildlike Behavior: Played for Laughs. When Moriarty warns Watson that he's about to get tricked by one of their cuter looking members, the girl immediately gives an unchildlike grimace before announcing she'll just go gambling instead. The girl later curses out Mycroft when he refuses to give her anything. Yoshio also calls for an adult beer "with gum syrup" when entering PCB once.
Moran Family
Cecilia Moran
Wife of Mayor Moran for eleven years before her death.
- Cruel and Unusual Death: She died of electric shock on her bathtub. It's worse - her own son killed her and watches her die.

- Posthumous Character: She was killed when James was young. "First Moonlit Night" suggest that an electrical device fell down in her bathtub and killed her by electric shock. "Moriarty Savors" mentions that James killed her by tossing a turned-on hairdryer into the bathtub.
Alexandra Moran
Voiced by: Kana Hanazawa
The daughter of Shinjuku Ward Mayor Sebastian Moran, she was targeted by Jack prior to the start of the series. She was also the person Watson and his team in West Shinjuku hospital conducted an autopsy on.
- Cruel and Unusual Death: She was stabbed in the abdomen and mutilated. Then, the Ripper cut out her womb and ate it.
- Cynicism Catalyst: She serves as one for her brother James. Her death affected him very much that he refuses to talk about it or let anyone know about it except Sherlock and Irene. This causes him to hunt down Jack the Ripper.

- Identical Twin Mistake: Jack the Ripper mistook her as her brother because she's wearing his clothes. But the Ripper doesn't mind because she's beautiful.
- Morality Pet: She's this to her brother. Her death made an impact on James which makes him very obsessed with finding her killer. After killing the Ripper and getting out of prison, James becomes more psychotic because, without his sister or his detective friends to keep him in check, he slowly descends into villainy.
- Plot-Triggering Death: Her death led to Watson into going to the East Side to meet Sherlock Holmes after finding a transmitter on her corpse and pushes James into staying in Kabukicho to find Jack the Ripper.
- Posthumous Character: She was killed before the show started just to show that Shinjuku is a Wretched Hive. She's actually a victim of Jack the Ripper.
Kate Carlyle
Voiced by: Kikuko Inoue (Japanese), Colleen Clinkenbeard (English)
The family assistant hired by the Morans. She nowadays works alongside Sebastian and helps James to remind him of his family duties.
- Advertised Extra: She shows up in the opening for the second half. But she rarely does anything plot-important after Moriarty ties her up and kills her. Turns out she is later revealed to be alive in "Everybody Be There By Eight", staying in the otherwise abandoned Moran mansion as a caretaker, and tells Watson some family background information that he passes to Sherlock in the finale.
Kaneko-gumi
Nobuo Kaneko
Voiced by: Katsuhisa Houki (Japanese), Kent Williams (English)
The boss of "Kaneko Financing", a Yakuza crime group thinly veiled as a loan company.
- Neighborhood-Friendly Gangsters: He was the one who arranged for Watson to escape to Kabukicho and seek Holmes' help, and is usually a friendly and respectable figure in the area.
- Reasonable Authority Figure: His leadership is marked by strict, but generally harmless loans and collections. Of course, it is likely that people know better than to take his mercy for granted.
- When Lucy failed to pay back her loan on time, he had her make up the difference by working at a host club, when everyone was genuinely afraid she would be forced into prostitution.
- When Toratarō essentially betrayed him by allowing a person who owed them money to skip town, he simply threw him out of the gang (which he wasn't suited for anyways), and patiently waited for him to work jobs until he gave back the equivalent amount.
- He decides to take the detectives' side over Sugimoto, one of his underlings, because the latter was more disruptive to the area.
Potter
Sugimoto's loyal henchman in his faction.
- Dumb Muscle: Averted. When Sugimoto did his rapping inside PCB, Potter corrected him when he introduced himself to Kobayashi.Potter: No [aniki]. He already knows who you are.
- Would Hurt a Child: Like Sugimoto, Potter has no qualms on hurting the Irregulars to do his boss' bidding.
Persons of Interest
Godfrey Norton
Voiced by: Tomokazu Sugita
Irene Adler's boyfriend who is a creator of sex dolls.
- Adaptational Jerkass: There's nothing much about Godfrey in the books except he loves Irene. However, in the show, he's an asshole and a pervert who is more focused on his dolls than his girlfriend. And at the end of "Wife Looks Into the Future", he skips town after it's revealed that his dolls produced an allergic skin reaction as seen with Kobayashi who is holding his groin in pain.
- Mythology Gag: His relationship with Irene harkens back to the original novels where Irene is introduced to be married to him.
- No Celebrities Were Harmed: His character background is similar to Steve Jobs or Tim Cook when Godfrey conducts a press conference.
- Replacement Goldfish: One of his sex dolls, Airi, looked exactly like Irene which is very creepy because he's letting customers have their way with her. Irene refers to herself as "Airi Version Zero" in a message to Watson.
Maki Hokari
Voiced by: Ayumu Murase
A regular customer of the Pipe Cat and a girl Kyogoku has a crush on.
- Big Beautiful Woman: She is not fat but is easily on the plump side.
- Crocodile Tears: After Sherlock and Watson cut her off and accuse her of being Jack the Ripper, she obviously fake cries and pretends to be innocent. After it's clear no one is buying it, she just comments that her tears ruined her makeup and starts to reapply it without a care.
- The Dog Was the Mastermind: It turns out the shy quiet regular at the Pipe Cat was Jack the Ripper the whole time.
- Driven by Envy: She started killing beautiful people because she was unable to undergo a sex reassignment surgery. Sherlock's constant snarks to her "small pecker" is most likely a reference about in real life if a penis is too small the surgeons are unable to craft a vagina with the material.
- Evil All Along: She turns out to be Jack the Ripper.
- Fourth-Date Marriage: Kyogoku proposes to her after a few dates. She says no only because she actually wants to get to know him more.
- I'm a Humanitarian: She reveals she eats the wombs of the women she kills.
- Inferiority Superiority Complex: Like many serial killers, Maki's motivated by pathological insecurity and lack of self-esteem. Because her penis is too small to reconstruct into a vagina, she can't have sexual reassignment surgery. To convince herself she's "perfect" in spite of this, she murders beautiful people and symbolically transforms their corpses into angels, perfect — and asexual — beings.
- Mind-Control Device: She used mescaline to make Kyogoku more suggestible.
- Monster Clown: The combination of her running eye liner and sloppily applied lipstick after she gets cornered gives her a Jokeresque appearance.
- Oh, Crap!: Has this reaction when she sees Kyogoku tied up by the rakugo stage, as she knows it was only a matter of time before they realize she is Jack.
- Professional Killer: It is revealed she is one when she isn't killing out of envious rage, saying "If I want to eat, I need to work."
