Proof that the Payne Train stretches back well into the annals of history. Prosecutor of DGS-1.

Personality: Like his descendants, Taketsuchi is all bluster and no bite. He's particularly prideful of his work and the Japanese government, and looks down not only on rookies but the young in general, believing they don't understand the finer points of politics.

Misc Facts: Carries a folding-fan with the kanji for "crime" on it.

Friends and Family: Ancestor of Winston and Gaspen Payne.

Name Origin:
Japanese: Like his descendants, "Auchi" comes from "ouch". "Taketsuchi" is quite visually similar to 武士, "bushi", meaning "samurai."

Background: Taketsuchi is a veteran, conservative prosecutor of the Meiji courts. While his skill is questionable, he seems to be trusted enough by the government to handle a top-secret trial.

A visiting professor from England, and victim of DGS-1.

Personality: Largely unknown, but by all accounts a good man.

Misc Facts:

Friends and Family: Friend of Yuujin Mikotoba, who invited him to Japan.

Susato's father, and a professor at Teito Yuumei University. Appears in DGS-1.

Personality: Yuujin is generally serious but not unkind. He's particularly pragmatic and down-to-earth, and well-aware of the power dynamics and politics of Japan.

Misc Facts: Nothing in particular.

Friends and Family: Father of Susato Mikotoba, mentor to Kazuma Asougi, and friend of John H. Watson.

Name Origin:
Japanese: "Yuujin" means "friend".

Background: Yuujin is a well-liked legal professor at Teito Yuumei University, and Asougi's mentor. In addition to being involved in the efforts to let Asougi travel abroad, Yuujin was the one to invite Watson to Japan to teach.

Waiter at the restaurant La Quantos, and witness of DGS-1.

Personality: Hosonaga is polite and courteous, and strives to do his best as a waiter and person. He views his thoroughness as a particular point of pride, and works tirelessly to improve his work. Still, he can be rattled surprisingly easily from time to time.

Misc Facts: From his constant coughing and the occasional bit of blood, it seems he has tuberculosis.

Friends and Family: None mentioned.

Name Origin:
Japanese: The kanji of "Hosonaga" mean "long and narrow", possibly a reference to his tall, skinny build.

Background: Hosonaga is a waiter at La Quantos, a western-style restaurant. On the day of the crime, he was the first person to apprehend Ryuunosuke and take charge of the situation.

A soldier who was dining at La Quantos at the time of the crime, and a witness in DGS-1.

Personality: Taizou is brash and confident, with no small amount of pride in his job and family. As a result, he tends to get a bit carried away and jump to conclusions, meaning he's not the world's most reliable witness.

Misc Facts: Seems to be rather a fan of beef cutlets, and he tends to just straight-up bite them rather than use knife and fork.

Friends and Family: Has an infant son, Koroumaru, who he carries on his back.

Name Origin:
Japanese: Possibly from "uzukumaru", "to crouch".

Background: Uzukumaru is your average soldier in Japan's imperial army, making ends meet for his family. On the day of the crime, he was dining with merchant Sanmon Sonohigurashi when they heard a gunshot and looked up to see Ryuunosuke standing over the victim.

A salesman who was enjoying dinner at La Quantos at the time of the crime. Witness of DGS-1.

Personality: Sonohigurashi is largely crochety and a bit unpleasant, with an eye for his business above all else. It also doesn't take much to shake him, but when provoked he can show surprising fierceness.

Misc Facts: Nothing in particular.

Friends and Family: None mentioned.

Name Origin:
Japanese: "Sanmon" means "three pennies", while "sonohigurashi" means "making a living day-by-day." The final impression is that of someone with a very poor lifestyle.

Background: Sonohigurashi is a somewhat grubby antiques seller who spends his days trying to hawk his merchanidse on anyone who'll buy it. The day of the crime, he was eating dinner with Uzukumaru when he heard a gunshot and saw Ryuunosuke standing over the victim.

An exchange student studying under Dr. Watson in Japan, and a witness in DGS-1.

Personality: Jezail generally acts the part of the gracious English lady, preferring to speak in the "Queen's English" and cooperating with whatever's asked of her. However, when under pressure she drops the veneer and shows a much more vicious side, as well as a not-insignificant amount of prejudice against Japan and its people.

Misc Facts: Yes, that's a real bird on her hat.

We never see her without the mask or without her hat tipped to obscure her eyes. Very mysterious!

Jezail peppers her speech with English, to the point that her unique shout - "Shut up!" - is presented in English even in the Japanese version. The game files show she also has a Japanese voice clip for "Matta!" ("Hold it!"), but it's never used in-game.

Friends and Family: None mentioned, though she and Asougi seem to be acquaintances.

Name Origin:
Japanese: From "J. Brett", as in Jeremy Brett - one of the more famous actors to play Sherlock Holmes.
