Witnesses and miscellaneous characters that appear in the spinoff Dai Gyakuten Saiban series. Here is the main character sheet.
Note: There are tons of spoilers for Dai Gyakuten Saiban covered below. Read cautiously!
A medical doctor and forensics professor at Yuumei Academy. Kazuma Asougi's mentor and Susato Mikotoba's father. A former student and colleague of John H. Watson.
- A Day in the Limelight: Part of DGS 2-5 has you play as Yuujin as him and Holmes are searching the SS Barabrook for Jigoku.
- Canon Character All Along: He's eventually revealed to be the Dr. John Watson from the books; the discrepancy in the names is due to a misunderstanding.
- Good Parents: He seems to be a fair and caring father to Susato.
- Leitmotif: Has two: As a standalone theme, "The Great Detective's Friendship", used in the reveal of him being Holmes' partner, and - together with Sherlock - "Partners ~ The game is afoot!", the main theme of DGS 2, used both in the reveal that he's Holmes' partner, and during the Joint Reasoning segment in the Barabrook.
- Meaningful Name: "Yuujin" means 'friend'. He's Sherlock Holmes' biographer and best friend.
- Narrator: As the real 'literary Watson', he's the one narrating the introductions to each case.
- Race Lift: Holmes' partner and biographer in the original stories, Dr. John Watson, is British - in DGS, Mikotoba is Japanese.
- Secretly Dying: Or at least really sick. In Case 5 he's in the hospital and he's been sick for several days and Susato needs to make an extremely quick trip home...except that's a lie, and he had that reported to take Susato back home after getting Souseki's report abroad - specifically details regarding the second case he's involved in. As for why, see Secret Keeper below.
- Significant Wardrobe Shift: In the second game's last 2 cases, he drops his traditional Japanese outfit for a suit-and-tie ensemble when he arrives in London, making him more closely resemble traditional depictions of Watson. On the final scene of Case 4, it's revealed that he was the actual Watson from the books.
- Secret Keeper: Until the end of the second game, he's the only other person apart from Sherlock who knows the true identity of Iris's parents. It's partially the reason why The Hound of the Baskervilles remained unpublished, and he had Susato come back from England to preserve this secret from Iris when the dog collar pops up during the Petenshy poisoning case.
- Secret Other Family: Subverted. The ending of DGS 2-4 implied that he had an affair while in London, fathering Iris in the process - though case 5 ends up disproving this theory.
- Skunk Stripe: The middle part of his hair is a snow white compared to his dark black hair.
A sergeant of the Imperial Japanese Army who witnessed Watson's murder in the restaurant La Quantos.
- Anti-Villain: He is unable to support his family because of his low salary and the high taxes that haven't been lowered from the last war, leading to him committing the series of thefts in La Quantos, so his son can have real food.
- Meaningful Name: 'Uzukumaru' means 'to crouch'. His son's name, Kuroumaru, comes from 'kurou', meaning hardship.
- Spanner in the Works: An unusual example, in that he very nearly ends up being this to the player rather than the culprit. Hiding Sonohigurashi's koban under his beef steak, followed by swapping said beef steak with Jezail's own steak, means that he unwittingly concealed the evidence that proves Jezail's guilt in the murder. If not for Jezail making a careless remark that proved the steak actually wasn't hers, he'd have caused Ryunosoke to be convicted instead of her.
- Trademark Favorite Food: Japanese-style beef cutlets. Even his Verbal Tic in the Japanese script forms 'cutlet' together!
- Villainous Breakdown: Once he is exposed for the string of thefts, Kuroumaru grabs his mustache and rides him like a horse before bending his back so far that the baby carrier flings to his front. The both of them then do a military salute.
An antiques dealer and owner of a store, 'Hall of Discard' (Ponkotsu Hall). Lost a koban at the time of the murder.
- Antiquated Linguistics: His method of speech, so much so that it baffles Ryunosuke.
- Chekhov's Gun: His koban ends up becoming important evidence to prove Ryunosuke's eyewitness account and Jezail's guilt.
- Meaningful Name: His name means 'making a pittance day by day'.
A transfer student from England who studied in Watson's laboratory in Yuumei.
- Big "SHUT UP!": Shut up! is her personal speech bubble, and it is rendered in Gratuitous English even in the Japanese-language game. It's even rendered in a fancy script! She's also the only one who uses it.
- Crazy-Prepared: Used curare, a poison that not only is totally unknown in Japan, but one that is only lethal by administering it through the bloodstream, and thus she (temporarily) disproves Ryuunosuke's theory by drinking the poisoned tonic water.
- Evil Brit: All these spoiler tags should make it pretty obvious. This actually causes a lot of problems, as the Japanese government wants to avoid prosecuting her out of fear of hurting Japanese-British relations.
- Eye-Obscuring Hat: When she doesn't use a mask to cover her eyes, her hat is always tipped in a way to keep them hidden.
- Faux Affably Evil: Acts like your typical refined British lady most of the time. She drops the act when she gets sufficiently angry, complete with yelling "SHUT UP!" at anyone who tries to interrupt her. She's also incredibly racist and xenophobic.
- Hidden Agenda Villain: She claims she had no motive for killing Watson. Her true motive is revealed in DGS 2; she's an assassin sent by Vortex to kill Watson in an area where extradition rights apply, since Watson knew too much regarding the truth of the Professor case.
- Karma Houdini: Downplayed and eventually subverted. After her guilt is revealed, the Japanese court is unable to persecute her for her crimes, due to the extradition treaty between Japan and England, but she is dropped off to British authorities in Shanghai with her fate after that unknown...until the sequel, where she is found dead in a beach house in the first case, a day before her scheduled deportation.
- The Killer Becomes the Killed: She's the victim of the first case in DGS 2.
- Leitmotif: "Elegant ~ and Excellent"
- Meaningful Name: Jezail bullet, as in a bullet from a Jezail rifle. Like the one that causes John Watson's injury in Holmesian canon. Her real name, Ann Sasha, is from ansatsusha - assassin.
- Nice Hat: She has a hat that has a swan design on it. How nice is this hat? It's not a design — it's a real, living swan.
- Politically Incorrect Villain: Very racist towards the Japanese. Downplayed, as this would have been fairly normal at the time the game is set, as British values tended towards the White Man's Burden.
- Refuge in Audacity: She destroys crucial evidence related to the case, in front of the entire courtroom. And she (almost) gets away with it too!
- Spell My Name with an "S":
- Bullet or Brett
- Her real name's an in-universe example when it first comes up at the end of DGS 1-5, namely that Susato and Ryuu are unsure whether it was "Satsushiya" or "Sasha" (due to how Japanese Morse Code doesn't distinguish between regular 'tsu' and the small vowel-lengthener). It's confirmed to be Sasha in the next game.
- Starter Villain: The first culprit of the game.
- Sudden Sequel Death Syndrome: The plot of the second game begins with her death.
- The Unintelligible: Downplayed. Her 'English' is rendered as unreadable doctor's cursive, and Hosonaga has to translate for her. Justified, as she is in a Japanese court. Some of her cursive text are intelligible English words like "Oh", or "What". She eventually drops her façade and speaks Japanese.
- Villainous Breakdown: She clutches her heart, then the swan on her head suddenly goes berserk and drags her around the room while she screams as baby chicks fly everywhere on the court. They then both fly towards a beam of light from the sky.
A senior board officer aboard the SS Alaclair. Was in charge of monitoring and security in the first-class cabin.
- The Dragon: Even though he didn't kill anyone, Stroganov assisted Nikomina in covering up the crime scene for her supposed murder of Asogui. He wasn't aware that she pushed Asougi in the first place while doing so, as he assumed it was entirely her cat's fault. He also made sure to make it seem like Ryuu was the main culprit and even before all of that, he and the rest of his crewmates drugged everyone else on board with sleeping pills in order to make an emergency stop to pick up Nikomina.
- Hair-Trigger Temper: It doesn't take much to set this guy off.
- Head Pet: The snake that is supposed to be the "speckled band" of the case is actually his pet and a Red Herring to the murder. Once the snake is revealed, it wraps around his head without any panic on Stroganov's part.
- Husky Russkie: He's pretty big and strong.
- Jerk with a Heart of Gold: Definitely not a nice fellow as he treats everyone (especially Ryuu) with hostility. However, he does have a soft side, as shown with how he cares for his pet snake and Nikomina.
- Morality Pet: Literally his pet snake, and figuratively Nikomina.
- Papa Wolf: Even though she isn't his daughter, Stroganov is fiercely protective of Nikomina and isn't afraid to fight for her safety.
- Punny Name: Meatloaf and stroganoff.
A Russian gentleman who resides in the room next to Asogi's.
- Adaptational Heroism: In the original Adventure of the Speckled Band, Roylott is a violent, short-tempered, horrible human being who had killed one of his stepdaughters and intended to kill another to obtain their parts of his dead wife's inheritance; in here, Nikomina is a meek ballet dancer seeking asylum in London who befriends a man in the neighboring cabin, but accidentally injures him following a misunderstanding.
- Adaptational Nationality: Roylott in the original SPEC descended from an aristocratic Anglo-Saxon family. Here? Russian.
- Anti-Villain: She really did not mean to injure Asogi. She just went through one of the most stressful days of her life, was already walking a tightrope trying to run from the Russian authorities, and had to reveal her true identity to a total stranger to get her cat back... then Asougi appeared to be going for the cabin's bell cord, and Nikomina panicked.
- Earn Your Happy Ending: After the case's conclusion, Sherlock cleared up the situation regarding Asougi to her and then helped her escape to America instead (since she still committed theft). Considering what she'd gone through, it's well-deserved.
- Foregone Conclusion: Played with. Case 2 is based on 'The Adventure of the Speckled Band', and those who did read it would know that Roylott is the killer - and then Roylott is revealed to be Nikomina. From that point, the details between SPEC and Case 2 begin to differ to the point of Deconstruction (in fact, the original solution is outright dismissed for reasons familiar to Holmes readers!)... except for who the killer is.
- Gender Flip: From a male, English doctor to a female, Russian ballerina.
- Little Stowaway: Subverted; not only do the crew know she's on the ship, they're the ones who help her get on the ship in secret.
- My God, What Have I Done?: Roylott's reaction when she learns what Asougi was really going to do after she told him of his identity is pure shock and regret.
- Paper-Thin Disguise: Roylott's disguise consists of a brown fake beard, Groucho Marx-esque glasses, and an Ushanka... with Nikomina's long, flowing blonde hair sticking out of it. In her defense, she had boarded the ship the night before and was just about to cut her hair off before Ryuu, Susato, and Holmes barged into her cabin.
- Poor Communication Kills: She pushes Asogi to his (assumed) death after wrongfully assuming the 'friend' he talks about was a detective.
- Punny Name: Nikomi is Japanese for stew. Borshevic may come from the Bolsheviks or borscht.
- The Runaway: Of the Abused and Orphan variety. She ran away from the Novavic ballet troupe after being exploited for her fame, has no surviving family or real friends except for the Alaclair crew and her cat, and no money on her name either since the troupe never paid her. She got along with Asogi nicely, but ends up accidentally injuring him in a panic.
- Samus Is a Girl: Though it's not long after we meet Nikomina that the identity is revealed.
- Shout-Out: Shares the same name with the antagonist of the Sherlock Holmes story The Adventure of the Speckled Band. Not so for her true identity.
- Shrinking Violet: Roylott's real personality is quite shy and timid. This doesn't change when Nikomina is revealed as the culprit.
- Spanner in the Works: Roylott couldn't have possibly known about any of this and probably still doesn't, considering she's at the other side of the Atlantic ocean at the series' conclusion, but incapacitating Asougi - and in the aftermath of the ensuing fake murder scenario, Sherlock appointing Ryuu as the replacement transfer student - meant Jigoku couldn't fulfill his part in the transfer assassination plot until a nearly a year after the case...where he decides to do it himself, leading to a series of events that led to Ryuu unraveling the Death Bringer conspiracy.
A notorious Russian revolutionary who had apparently fled to London. Sherlock suspects Roylott of being him.
- Brick Joke: He appears for real in Case 5, as Juror 6.
- Gun Nut: He hasn't been seen with any guns but he does claim to know a lot about guns having researched many ones.
- Punny Name: Demiglaski is from demi-glace.
- Red Herring: Despite having a distinctive design and being a revolutionary, he ultimately has no relevance to Case 2 and is never mentioned again beyond the first Joint Reasoning session.
- Suspiciously Specific Denial: He would like you to know that he's just a regular tourist off to see the Crystal Tower, and definitely not a Russian revolutionary.
A rich businessman, philanthropist and park owner. Defendant of the third case.
- Asshole Victim: He dies at the end of Case 3, and he's not exactly the paragon of morality.
- The Bad Guy Wins: Subverted. He is wrongfully acquitted, but is murdered very soon after.
- Big Bad: Ultimately he's this for Dai Gyakuten Saiban: Naruhodou Ryuunosuke no Bouken, even in death.
- Bitch in Sheep's Clothing: On the surface, he's a kind, well-respected man. Underneath, however, lies a Loan Shark who is more than willing to get his own hands dirty.
- Cruel and Unusual Death: Getting locked inside a carriage and being burned alive definitely counts as this.
- Expy: He's basically Redd White in a top hat, he even has similar mannerisms. Fittingly, he's also a Bitch in Sheep's Clothing.
- Evil Brit: He's a villain that, like everyone in these games, is British.
- Evil Laugh: The laugh he gives off when he wins the trial counts as this at that point in time, complete with Evil Gloating, to boot!
- Hidden Agenda Villain: While the motive for the murder of Morta Milverton is clear, the reason why he was to leak government secrets remains unknown as of yet.
- The Killer Becomes the Killed: Killer of Case 3, ends up being killed himself in the same case.
- Laser-Guided Karma: He is killed by Rubert Crogley, the son of the man he murdered, shortly after winning the case in which he was accused of the murder. And in the very same crime scene!
- Loan Shark: What he actually is. It's implied that this is his motive for murdering Morta, though this is proven false later on.
- Nice Hat: It takes up almost half of the height of his 3D model!
- Nonstandard Character Design: Though his sort of style is the standard for most Londoners.
- Posthumous Character: Remains an important character in the game even after his death.
- Uncle Pennybags: Is a rich guy who hands out money like cheap candy to the poor, and is well-liked by most of London. It's all a front.
- Villainous Breakdown: When Ryunosuke begins to catch on to what he's actually doing, he blows up in anger and bangs the witness stand with his fist, while insulting Ryunosuke and Barok. He regains his composure when it turns out it's too late to change his verdict, leading to him applauding on the stand as the gallery reacts in confusion and anger.
- Villain with Good Publicity: He's well-respected among the community, but in reality, he's a heartless Loan Shark who is willing to murder.
- Walking Spoiler: It's really hard to talk about him without giving away that he's the killer of case 3's victim and dying in the same episode he was accused in (plus the whole information stealing that serves as an important backdrop in the last case).
The coachman of the Phoenix Wright Omnibus, and a witness to the murder. He (or someone who looks like him) also moonlights as a street vendor under the alias 'Sandwich' (see Twisted Karma and His Last Bow below).
- Chekhov's Gunman: See Not-So-Small Role.
- Not-So-Small Role: Only revealed after Case 3, but Megundal bribed him into taking his bloodstained coat to Hutch's pawn shop. The coat happened to contain one of the discs with state secrets on it, which results in Megundal's accomplice needing to break into the pawn shop to get it back. Without this, Case 5 would never have occurred.
- Shout-Out: From the Holmes' story The Adventure of the Six Napoleons.
A banker who witnessed the crime onboard the omnibus at the time of the murder.
Returns in Case 4 (and DGS 2 Case 2) as Juror #1.
- Know When to Fold 'Em: He's a very abrasive personality, but true to his name, he knows when to fold.
- Punny Name: Refers to the term "fair play," referencing his personality.
- Red Herring: At some point in the trial, Ryuunosuke establishes a possible motive involving his debts to Megundal. It turns out to be irrelevant to the case.
A milliner-in-training who witnessed the crime along with Fairplay.
The famous poet and author of Japanese literature, and defendant of the fourth case.
- Acquired Situational Narcissism: He gets a bit of an inflated ego in DGS 2-1, following the success of I Am A Cat's serialization.
- Artistic License History: A slight case. Soseki was born in 1867, and since he is 33 in Case 4, it means that the year in which it is set is 1900. But Soseki, in real life, was present in the United Kingdom only from 1901 to 1903. Also, in DGS 2, he returns to Japan two months after Case 4 of the first game, but in real life, he returned to Japan only after his stay in the UK had ended.
- Fish out of Water: He hasn't been in England for very long when the case starts. It's part of the reason why no one would defend him; no one in England would rush to the defense of a strange foreigner who fled from the crime scene, on top of the fact that "The Reaper" was taking the case. In fact, when he sees Ryuunosuke and Susato, he was more ecstatic at seeing other Japanese people in London rather than Ryuunosuke being a defense attorney.
- Historical Domain Character: A first for the series.
- Kindhearted Cat Lover: He owns a cute cat named Wagahai.
- Leitmotif: "I Am Innocent".
- Nervous Wreck: A very anxious man with trouble fitting with the Londoners, all while looking behind himself periodically for no other reason but general paranoia.
- Never My Fault: Repeatedly blames Holmes for his arrest, and the detective eventually calls Soseki out on it by pointing out that Scotland Yard were the ones who made the accusation, based on the testimony of the O'Malleys, and that all he did was find out exactly who Soseki was and where he lived. And had Soseki actually stopped to help Viridian Green instead of just running away, he probably would never have been a suspect in the first place.
- Stock Poses: From "Super Sentai" Stance poses to pec flexing, Soseki is rather fond of pulling various poses.
- Wholesome Crossdresser: He dresses up like Juliet when he and Petenshy have a sparring match to decide "who is stronger, Romeo or Juliet".
- Chekhov's Gun: Not exactly her, but the cat door maker Iris made for her.
- Cute Kitten: She's not a kitten, but she does have one!
- Punny Name: Her name comes from Wagahai wa Neko de Aru, or I Am A Cat, by Natsume Soseki.
Soseki's landlord, and a retired veteran who received a knee injury back when he was in service. He rents out rooms in his house.
Returns in Case 5 as Juror #1.
- Bridal Carry: oan does this to him after he faints once Sherlock and Ryuunosuke figure out that Joan is his wife and they had a quarrel the night of the attempted murder. Attempts to do this with a fainted Joan in their breakdown once their part in the incident is revealed in court, with less successful results.
- Dual Boss: With Joan.
- Fat and Skinny: The skinny to Joan's fat.
- Henpecked Husband: To Joan.
- Mistaken for Cheating: A love letter was used as a bookmark by the previous owner of the second-hand book he brought. Joan sees it and goes ballistic... and thus led to Viridian Green's stabbing.
- One Steve Limit: Averted. He shares the first name as John Watson.
- Phony Veteran: Well, he's an actual veteran, but he's not as decorated or well-compensated as he would want people to think he is, hence his wife posing as his maid.
- Shout-Out: The surname comes from the Sherlock Holmes story 'The Adventure of the Three Garridebs'.
Garrideb's maid. She is selected by the courts to be the fifth juror in the Viridian Green assault trial.
- Accidental Murder: Well, attempted murder, but this is what she ends up doing.
- Bridal Carry: She carries Garrideb like this after he faints following the Joint Reasoning segment. Garrideb later tries to do this with her after she faints in court, with less successful results.
- Dual Boss: With Garrideb.
- Food Slap: In her disguise as maid, repeatedly pours hot tea onto John's lap in anger at his perceived infidelity. Continues even after the John tried to clarify her assumption
- Fat and Skinny: The fat to Garrideb's skinny.
- Shout-Out: Her real surname, "Garrideb", comes from the Sherlock Holmes story 'The Adventure of the Three Garridebs'.
Patrick's wife, and a witness to the incident. Very proud of her husband.
- Motor Mouth: Does most of the talking when called up to the stand with her husband, since Pat is exhausted from the constant patrols. However, her volunteering more testimony inadvertently leads to ....
- Nice Job Fixing It, Villain!: Her testimony saves Ryunosuke from disaster twice and without any prompting too. Her commenting on the number of books helps link the Garridebs to the stabbing and her commenting on Pat's patrol beat ultimately causes Pat to reveal that he had moved the scene of the crime, thus offering the defence the possibility of a different attacker
- No Sense of Direction: Which is why she doesn't notice that the victim had been moved to the other side of the street.
- Punny Name: Pat+Rola = Patrol.
- Sickeningly Sweethearts: With Patrick.
- Spell My Name with an "S": Rola or Lola? The fan translation uses the former, probably to make the Punny Name more noticeable.
Two strange and out-of-place men that briefly appear to argue in front of the Garrideb household. Both later appear in the sequel's second case, Mysterious Man A being the victim and Mysterious Man B being a witness. For tropes regarding the former, see William Petenshy below; for those regarding the latter, see Decargo Mieterman below.
An art student from Thorndyke University who was stabbed in the back in the knife. The first victim (outside of PLvsAA) to be still alive after the incident (she was put in a comatose state). She returns in DGS 2 after she recovers from her coma.
- Always Murder: Completely and notably averted in her case (unusually for this series), as she is not dead at all. Indeed, even her intended victim was not killed either.
- Anti-Villain: She only wanted to kill Petenshy because he, as part of a scheme of his to force him out of his room, instead unwittingly killed her fiance. She also set up her poison in such a way that Petenshy would only poison himself if he was truly guilty of her fiance's death and tried to do the same thing to someone else.
- Big-Bad Ensemble: With Petenshy for the second case of the sequel. Both of them are culprits, but aren't working together: Petenshy unwittingly killed Duncan Ross years ago and might have done the same to Souseki, while Viridian attempted to kill him both as revenge for Ross (her fiance) and to protect Souseki.
- Convenient Coma: Goes into a coma after being stabbed, and started to recover from it after the case was solved.
- Curiosity Killed the Cast: How she got stabbed. She tried to pick up a burnt book that seemingly fell from nowhere, only for a knife to fall from the same source blade first into her back.
- Despair Event Horizon: After Ross' death, she fell into a deep, deep depression.
- Driven to Suicide: She tried to kill herself while in the hospital with the same poison she used to attempt to kill Petenshy. Sherlock saves her just in time, but it ends up implicating her later.
- Eureka Moment: Has one when she hears Souseki talking about the "cursed apartment" and the gas lights going out, leading her to realize that Duncan Ross' death might not have been an accident after all.
- Innocent Bystander: She had nothing to do with any of the characters. She was just in the wrong place at the wrong time...except not really. She was actually there to kill William Petenshy.
- It's All My Fault: She blames herself for Duncan Ross' death, thinking that, if she had tried harder, he would've survived.
- Only Mostly Dead: She's in a coma.
- Repetitive Name: Viridian (her first name) is a shade of green (her surname).
- Sympathetic Murderer: Would-be murderer, anyway. She attempted to murder Petenshy, in an act of revenge for the death of her fiance as well as preventing his reckless criminal behaviour from harming anyone else.
- Walking Spoiler: Its a bit hard to talk about her without revealing her true motives for being at Briar Road.
- When She Smiles: It happens twice. The first is a smug smile when she reveals that she already had the key that Petenshy was so desperately looking for. The second is after she explains he reasoning to kill Petenshy, and, after a brief conversation with Ryuu, she smiles and bows at him.
Egg Benedict Rupert Chrogray
A mysterious gentleman who appears in Hatch's pawn shop. Has a tendency to twirl around like a ballroom dancer.
- The Ace: Case 5's Juror #5 is one of his fangirls and shows him as this in his line of work.
- Accidental Murder: Played with. He really didn't mean to kill Hutch, he just fired his gun out of panic and happened to hit him in the heart. However he was at the pawn shop to steal back the discs containing state secrets, which is already a capital crime in itself and his murder of Megundal months back was very much planned.
- Big Bad Duumvirate: Despite not being as powerful or influential as Megundal, he is still considered a force to be reckoned with, due to his easy access to top secret government info.
- Bishōnen: He is quite pretty and flamboyant.
- Determinator: He gives Alba a run for his money in sheer tenacity.
- Everything's Better with Spinning: Some of his damage animations cause him to spin out of control.
- Evil Brit: A British antagonist.
- Final Boss: The final witness and murderer. However, the Big Bad is someone else.
- Freudian Excuse: He was born in poverty and came to resent his early life because of that. Even after getting a respectable and well-paid job as a telecommunicator, he wanted more money, hoping that it would help him to forget about his life in the ghettos. That's what leads him to accept Megundal's deal and steal secret information from the British government.
- He Who Fights Monsters: Admits he became just as bad as Megundal in his scheme to get revenge on him.
- Light Is Not Good: Dons a gaudy white suit with a matching top hat, but does nothing to hide how truly sinister he is.
- Marathon Boss: Takes the entirety of the last two parts of the final case's trial to defeat. Not helped by the fact that he's assisted by Gregson in the last legs of the trial.
- Obviously Evil: The fact that he pulls a gun on the protagonists before the murder plot even starts is proof enough that he's not just your average witness.
- Punny Name: "Eggs benedict."
- Rags to Riches: Grew up poor before getting a comfortable, well-paying job.
- Villainous Breakdown: He breaks his cane on the witness stand, then he attempts to strangle Gregson with it.
- "Where Are They Now?" Epilogue: Notably the first murderer in the entire series to actually have one in the game he debuted in, which he shares with the Tinpillar Brothers. He sulks a bit before the Tinpillar brothers cheer him up, vowing to break all three of them out of prison to start new lives as dairy farmers.
- You Killed My Father: His motive to kill Megundal.
Nemmy and Tully Tinpillar
A small-time criminal duo. They broke into Hatch's pawn shop and witnessed the murder.
- Blatant Burglar: Including Domino Mask and everything.
- Dual Boss: They both testify together.
- Even Evil Has Standards: They may be self-proclaimed villains, but they draw the line at national treason.
- Expy: The mustaches, size difference (in height and width) and red and green color schemes all point to them being Mario and Luigi, but as burglars instead of plumbers.
- Fat and Skinny: Nemmy is skinny, Tully is fat.
- Long-Lost Relative: For whatever reason, they believe Gregson to be their long lost brother.
- Minion with an F in Evil: They actually hinder Crogley more than truly help him, frequently through slips of their tongues or contradicting testimonies.
- Stupid Crooks: They're both dim-witted and incompetent, either as criminals or as witnesses.
- Terrible Trio: With Crogley included, they actually form a classic one, with a haughty leader and two buffoonish minions.
- Trademark Favorite Food: Pears for Nemmy, apples for Tully.
Debuted in Dai Gyakuten Saiban 2: Naruhodou Ryuunosuke no Kakugo
A forensics student under Yuujin Mikotoba and Susato Mikotoba's close friend, who is put on trial for the sequel's first murder. Was formerly under Dr. John Watson's department before the latter's death.
- Bad Liar: To say she's bad at playing along with Susato's "Ryutaro" disguise would be an understatement. She slips up and calls her by her real name constantly.
- Character Development: Over the course of the trial, Haori goes from clumsily referring to Susato by her real name instead of her disguise name to judo-tossing the culprit (with Susato's help).
- Curtains Match the Window: Her eyes and hair are both black.
- Hime Cut: Haori wears her hair in this style, fitting her traditional Japanese wear.
- Meaningful Name: A haori is a Japanese garment that resembles a coat, and Haori dresses in a very formal fashion. "Murasame" can translate into either "rainy season" or "autumn rain", and "murasame" typically refers to rain that starts and stops suddenly, or falls hard and then gently in fits and starts. This fits Haori going from reserved to judo-tossing the culprit.
- Red Oni, Blue Oni: The Red to Susato's Blue.
- Took a Level in Badass: At the end of the first case's trial, Haori becomes one of the first defendants in the series to deal with the culprit who framed her personally, by physically stopping his breakdown sequence and then giving him a judo toss with Susato's help.
A journalist who was following Souseki around for a story regarding his visit to Yuumei Academy.
- Anti-Villain: Despite undeniably being an arrogant jerk with no qualms about letting an innocent woman be convicted for his own crime, he shows shades of this. He has convinced himself that his own justice is the only absolute kind, and that he has to take it into his own hands to uncover the truth at any cost.
- There's also the fact that his murder is yet another heat of the moment murder in which he killed Brett especially after she was racist towards him. He planned on killing her before, but this sealed the deal.
- Chekhov's Gunman: His first appearance in the case is as an animation gag regarding Souseki's poses before being brought in as a proper witness to the case.
- Curtains Match the Window: His hair and eyes are both brown.
- Going for the Big Scoop: He appears in the case because he was following Souseki around for a story. He was aiming for another story as well, namely the poisoning of Dr. Watson, but when he came to Brett for an interview she rudely dismissed him. On another note, a story he wrote regarding government backdoor deals prolonging Brett's deportation was rejected by the newspaper he worked for.
- Intrepid Reporter: Subverted in the case of Brett's murder, as he turns out to be the murderer. Played straight for the other things he was investigating, like the backdoor deals and the matter of Kazuma Asougi not making it to England.
- Leitmotif: "Reporter Mamemomi's Justice"
- Knight Templar: Seems to have originated as a fair and honest journalist, but the things he learnt about his country, and Jezail Brett's lack of punishment drove him to his cynicism and led to his crime.
- Villainous Breakdown: He swings his camera around, ranting that nothing of this is ever his fault, the Japanese empire is bending to foreign powers so he had to do it, he battles day and night for the sake of news and works only for justice, until Haori stops him by grabbing and putting down his swinging arm. Then she and Susato toss him up high into the air and get into fighting stances right before he lands.
- Wild Take: When contradicted, Heita either clutches a pencil in his fist hard enough to break the pencil, or he rears back with his arms outstretched as his cap falls over his face. Later, as he testifies with his cap off, he does the same rearing-back pose but without the hat over his face.
A mysterious fancily dressed man who is first seen in Case 4 of the previous game as one of the tenants of the Garrideb household. A "washed-up actor", as Gregson (and others) would describe him, and was once arrested for being a con-man. Winds up a victim of strychnine poisoning, though he recovers and sues Souseki for attempting to kill him.
- Asshole Victim: He's not dead, but he's an ex-convict willing to do anything to get his hands on a fellow inmate's treasure, and in his attempt to get Duncan Ross out of his apartment by causing a gas leak ended up killing him. Not only that, he planned on doing the same thing to Souseki, despite knowing someone died the last time he tried that. Viridian Green actually set it up this way: she put strychnine on the end of the gas pipe so Petenshy would only poison himself if he tried the same gas trick again.
- Big-Bad Ensemble: With Viridian for the second case. Both of them are culprits, but aren't working together: Petenshy unwittingly killed Duncan Ross years ago and might have done the same to Souseki, while Viridian attempted to kill him both as revenge for Ross (her fiance) and to protect Souseki.
- Big Entrance: His entrance into the courtroom.
- Bitch in Sheep's Clothing: Behind his polite exterior lies a ruthless criminal who's willing to go to any lengths to get his hands on 1000 pounds of treasure.
- Con Man: Used to moonlight as one, which is why he has a criminal record.
- Drama Queen: Male example. He is pretty theatrical in his movements, especially when he bids farewell to others. After Sherlock's Joint Deduction segment regarding his poisoning when he was passed out on his table, he briefly wakes up and recites the 'sound and fury' soliloquy from Macbeth (or at least tries to - he forgets the line halfway and has Gregson finish it) before collapsing.
- Dramatic Spotlight: When he awakens from his poisoning and when he enters the courtroom, a spotlight is shone on him.
- Early-Bird Cameo: Is introduced in the first game, though he has no importance in the case itself.
- Giant Poofy Sleeves: As part of his getup.
- I Didn't Mean to Kill Him: After his breakdown, he confesses that he wanted only to drive Ross out of his room. He never meant to kill him.
- I Resemble That Remark!: He likes using the Hamlet quote "one may smile, and smile, and be a villain" in reference to others, not realizing it sums him up pretty well.
- Karmic Death: He didn't actually die, but he was the target of one of these. Viridian poisoned the end of his room's gas pipe so that if he attempted to gas Souseki's room in the same way he did Duncan's, he'd poison himself.
- Large Ham: As shown by almost every pose he does. Even when he goes kind of nuts, he still acts like this.
- Leitmotif: "Elegant ~ and Excellent" in DGS 1, and "Shakespeare of the Slums" in DGS 2.
- Meaningful Name: His first name's an obvious reference to William Shakespeare, and his surname, Petenshy, means "crook" in Japanese. He's an ex-prisoner who has done a few nefarious things to get a treasure promised him by a serial murderer.
- Nice Hat: A large striped one. It's off after his breakdown.
- The Nicknamer: Calls everyone "Horatio" when acting like Hamlet.
- No Name Given: In the first game and is known only as "Mysterious Man A" in that game's artbook.
- Regal Ruff: Wears one as part of his thespian garb.
- Shout-Out to Shakespeare: Constantly references Shakespeare and thinks himself good at debating others about his works.
- Slasher Smile: He starts smiling like this after his intent to obtain Selden's treasure is found out. It, along with his usual posing, makes him look like a madman.
- Smug Smiler: Is one by default, at least in his first appearance.
- Staff of Authority: Frequently shown holding one and using it in his poses.
- Villainous Breakdown: Grimacing and clutching his chest, he then stumbles across the witness stand as confetti bursts from his chest, and one of the jewels on his chest falls off. This happens twice as he gets into two theatrical poses. Eventually, he jumps up and strikes one more pose before being felled by a final burst of confetti.
An irritable, large-chinned man who works for Altamont Gas Company. He is called as a witness to William Petenshy's poisoning.
- Animal Motif: Bees, mostly noticeable when he points sideways, trailing his yellow-striped bag behind him. Fittingly, he's something of an Extreme Doormat to Mrs. Altamont, making him the drone to her queen.
- Early-Bird Cameo: Though he's formally introduced in this game, he appears in a single scene during The Adventure of the Clouded Kokoro, arguing with Petenshy.
- Lantern Jaw of Justice: Not quite heroic, but he has a massive chin.
- Punny Name: His name's a portmanteau of 'dekai' ('big') and 'ago' ('chin'). His last name ('mitaman') is a pun meaning either 'man who saw it' or 'saw it all'.
Juror No. 4 for the Petenshy poisoning trial, and the wife of the director of the Altamont Gas Company. She had been sending Decargo over to Petenshy's place over suspected gas theft.
- Absent-Minded Professor: Has this sort of air about him. Barok even remarks that Benjamin has forgotten his name on numerous occasions (and they were university buddies)!
- Companion Cube: He considers all his tools "friends" and has names for them all. The screwdriver that was the murder weapon is "Andrew", and he has another screwdriver named "Michel".
- Leitmotif: "Science Boy"
- Unwitting Pawn: Twofold, even. Meningen funded his experiment and collaborated with Drebber to get the funding money, while Drebber worked on his machine as a part of a ploy to kill Meningen.
- Leitmotif: "Mysteries Pressed in Wax"
- Nightmare Fuel Station Attendant: She can go on at length about some... disturbing subjects, such as making wax figures from dead bodies. In fact she's physically handled corpses before in order to capture their likeness. She doesn't seem to realize or care that she's creeping people out.
- No Historical Figures Were Harmed: Pretty much DGS' version of Marie Tussaud (of Madame Tussauds fame) - aside from the whole three generations down thing. Complete with the Madame Rozaic's museum being a Bland-Name Product of the aforementioned museum!
- Punny Name: Her surname comes from the Japanese word for waxworks.
- Red Herring: She's introduced early on and doesn't testify in the first day of the trial, her Leitmotif sounds very sinister and it becomes increasingly apparent that her wax museum is important to the case. If you think that means she's the culprit... you're wrong.
- Secret Keeper: As the one who sculpted The Professor's wax figure, she's one of the only people who have seen his face. As his identity is considered a national secret, the wax figure is stored in a secret room in her museum, covered with a mask that can be opened only with her key.
Wilhelm Gottsreich Sigismond Ormstein
- Brick Joke: Iris claims that the name "Wilhelm Gottsreich Sigismond von Ormstein" was made up when Susato brought up 'A Scandal in Bohemia' in the previous game's Case 4. As it turns out, there actually is a Bohemian royal with that name (maybe even two!)
- Full-Name Basis: Demands everyone refer to him by his full name. Naturally, no-one is able to, only calling him "Gotts".
- Never My Fault: When he produces a photo to prove he's not lying about seeing a green balloon... and it's in black and white, he demands the court blame whoever made the camera.
- Overly Long Name: Ryunosouke can't even come close to memorizing it.
- Royal Brat: His royal status is ambiguous, but he's definitely a brat, throwing a tantrum in court if anyone disagrees with him.
- Shout-Out: Shares the same name with the Bohemian king featured in the Sherlock Holmes story A Scandal in Bohemia. Apparently said king does exist in this universe and this Gotts is his son according to Sherlock in Case 4's Joint Reasoning segment, but considering that Sherlock misremembered his nationality, that may be up for debate.
- Berserk Button: Doesn't take lightly to even the implication that his balloons might be unsafe.
- Big Fun: A rotund and jolly man. Most of the time, anyway.
- Nice Hat: One that looks (and functions) like a hot-air balloon.
- Punny Name: "Rumba" is nearly an anagram of "balloon" (in Japanese), and "Marmatch" comes from "marumachi", "round".
- Big Bad Duumvirate: With Sithe in the third case.
- Cyborg: Certainly looks like one (or the Steampunk equivalent, anyway) - even his movements make whirring noises.
- Freudian Excuse: He used to be a promising young scientist, who won a royal award and was considered a genius...until Meningen's newspaper publicized his discovery of "the Professor", which exposed him as a grave robber and got him expelled from university. He's held a serious grudge against Meningen ever since.
- The Ghost: For the first two-thirds of the case. Drebber is very reclusive, and doesn't even list his address on his business card. Tracking him down forms a good deal of the second day's investigation.
- Grave Robbing: His "side business" while he was a university student. If he's to be believed, he wasn't the only student who did this.
- Leitmotif: "The Link Between Science and Magic"
- Obviously Evil: The moment you track this guy down, the game makes no attempt to hide that he'd bad news: it's clear he hastily destroyed evidence just before you searched his room, and the second investigation day ends with him indirectly confessing to setting a time bomb at the crime scene, possibly killing several police officers. However, while he had a big role in Meningen's murder, he wasn't the one who physically killed him.
- Prematurely Grey-Haired: A wax figure of his past self sports normal-looking hair. Only ten years later, his hair's gone completely white. In fact, his hair apparently went white immediately after witnessing the Professor's "resurrection".
- Revenge: His motive against Meningen, for publishing the newspaper article that got him expelled. He also wants revenge against all of Scotland Yard for their involvement in his humiliation, which is why he coerced Sithe into helping him.
- Shout-Out: Named after the victim in the Sherlock Holmes story A Study in Scarlet.
- Unwitting Instigator of Doom: His stumbling onto "The Professor" rising from his coffin while gravedigging is what prompts Vortex forcing Jigoku to kill Genshin before anyone can find out his execution was staged.
- Ascended Extra: In-universe, most of the jurors Ryuu meets are never seen again... except for her. She kickstarts a major portion of the fourth case, which is locating her husband.
- Expy: Pretty much DGS's version of Mrs. St. Clair from The Man with the Twisted Lip, including the missing husband and not knowing about his secret life.
- High Class Gloves: She's definitely looks the part of a high-class woman.
- Driven to Suicide: He had attempted suicide by jumping off a five-story window from Barricade's office after being fired for his (supposed) involvement in the Professor's escape. He lives through it, though it altered his memories of the event.
- Expy: Pretty much DGS's version of Neville St. Clair from The Man with the Twisted Lip, right down to disguising as 'Hugh Boone'.
- Heroic BSoD: After remembering that he was fired, and the truth about the Professor case, the screen smashes like a window, and he screams and faints, falling onto the floor.
- Unconfessed Unemployment: He hid the fact he was no longer working at the prison from his wife and working for Inspector Gregson under his Hugh Boone identity.
- Who Names Their Kid Everyday: Although Anna seems to use it to call him her everything...
"Venus", "Gossip", and "Sandwich"
A trio of street vendors who were working near the crime scene when the murder happened. 'Venus' peddles wares (fireworks in particular), 'Gossip' is an information broker, and 'Sandwich' is a 'sandwich man', or a 'bumvertiser' (i.e. a homeless man paid to advertise) who looks like Beppo, the carriage driver from the previous game, though Ryuunosuke describes him only as "familiar".
- Consummate Liar: Venus. Asougi especially keeps calling her out on it.
- Gonk: Gossip, what with his twisted lip. It's a disguise, as you will have figured, if you've read The Man with the Twisted Lip.
- Knowledge Broker: Gossip's work is an information broker.
- Ice-Cream Koan: Sandwich is particularly fond of saying things in this manner.
Maurice de Quilco and Marco di Gicho
- Big Eater: Marco's shown eating food when he and Maurice appear on the stand.
- Blue Blood: According to the two of them, Maurice is descended from French aristocrats and Marco is the third son of an Italian landowner.
- Fat and Skinny: Maurice is skinny, and Marco is fat.
- Loose Lips: During their testimony, Marco keeps trying to talk about the officer that went to the Red-Headed League, though Maurice tries to tell him to shut up about it. And it's Marco who reveals that Gossip's name is Hugh Boone.
- Military Salute: They enthusiastically give one after the judge orders them to detain Hugh Boone.
- Ocular Gushers: They cry during their testimony.
- Redhead In Green: Marco's clothing. Maurice's is more blueish.
A sailor on-board the SS Barabrook, and Mitrov Stroganov's brother.
- Strong Family Resemblance: Looks identical to Mitrov, to the point that the only distinguishing feature between the two of them is that Mapotov has a fringe of blonde hair hanging from his hat.
- Punny Name: Mapo tofu and stroganoff.
The Queen of the United Kingdom of Great Britain and Ireland and Empress of India. Ends up being made audience to the Gregson murder trial thanks to Holmes' two-way holographic transmission.
Due to the semi-canonical nature of these cases, these characters have their own folder (merged into one due to the cases' relative length).
Apparently the highest scoring candidate in the tests for the Law Exchange Program...
Taketsuchi Auchi's son, and the third-ranking candidate...scoring 200 points below Kazuma Asougi.
Chalan Musgrave's younger brother. Sherlock arrested him on the way to the trial.
