Visual Novel / Dai Gyakuten Saiban: Naruhodou Ryuunosuke no Bouken
aka: Dai Gyakuten Saiban
A new age of law begins note 

A spin-off of the Ace Attorney series of games for the Nintendo 3DSnote , starring the Meiji-era Japan version of a defense attorney, Ryuunosuke Naruhodou, ancestor of Ryuichi Naruhodou/Phoenix Wright. The main writer is Shu Takumi instead of Takeshi Yamazaki, whose team was working on another Ace Attorney title at the same time.

It is the Meiji Restoration period of Japanese history (specifically, the beginning of the twentieth century AD); a time of great cultural shift towards a growing trend of westernization in Japanese lifestyle and architecture. Among those taking advantage of the new opportunities the era affords is one "Ryuunosuke Naruhodou", a second-year student at the Teito Yuumei University. Things suddenly change for the young man when he is accused of murdering a man in a restaurant. Forced to stand trial in the newly established court systems of the period, Ryuunosuke begins a long journey of justice that will take him well beyond the shores of Japan.

You can watch the original teaser trailer here and the Tokyo Game Show 2014 trailer here (both trailers contain English fan translations). A new five-minute trailer was released on April 1, 2015, which can be viewed here (trailer also contains subtitles).

The game was released on July 9, 2015 in Japan. There has been no announcement of release to other markets as of yet. A sequel, Dai Gyakuten Saiban 2: Naruhodou Ryuunosuke no Kakugo ("The Great Turnabout Trial 2: The Resolve of Ryuunosuke Naruhodou") has been announced, with a teaser trailer released on September 17, 2016.

This work provides examples of:

  • Absence of Evidence: In the second case, the blank pages in report book suggest Stroganov was absent from his post.
  • Always Murder: Subverted in case 2, which turns out to be a case of accidental manslaughter, and completely averted for the first time in the series with case 4, as the crime is assault. And even then it turned out to be an accident.
  • Anti-Frustration Features: As with Dual Destinies, you can go to any point in the map wherever you are instead of having to go to certain locations to get to others and during the investigation phases, items you already looked at are given a checkmark.
  • History Repeats: This isn't the last time that a Naruhodou/Wright stands accused of murdering their own mentor.
  • Identical Grandson:
    • Series regulars would get no points for being able to guess who this fine gentleman would be related to in the modern era.
    • And, of course, Ryuunosuke basically looks like Phoenix but with a more sensible haircut (and de-aged by about five years or so).
  • Idiosyncratic Episode Naming: Unlike the main series' use of "Turnabout" in all its case titles, here all the case titles include "The Adventure of..."
  • Karma Houdini: Jezail. Due to the treaty between Japan and England, Jezail can't be tried in Japan. At best, they would be sent to authories in Shanghai where maybe they go to court.
  • Kid Sidekick: Iris Watson to the great detective himself.
  • Left Hanging: These points weren't explained, likely due to the writer wanting to make a series.
    • Jezail's motives for killing Watson.
    • What Asougi's mission is.
    • Why did Barok leave the court, what's the truth about his "curse" and who was Barok's traitorous friend and what exactly happened.
    • What was Megundal's plan with the government information?
    • Why can't The Hound of Baskervilles be published and why does Susato know the title despite it being unpublished.
    • The meaning of the message in the disk in Japanese morse code we heard at the end of case 5, what the four people in said message had to do with the government, and the identity of "A.Sasha".
  • Literary Agent Hypothesis: Iris Watson is the author of The Adventures of Sherlock Holmes in this universe.
  • Martial Arts Headband: The headband Kazuma Asougi wears resembles one.
  • A Protagonist Is Ryu: Ryuunosuke Naruhodou (which makes sense since they're trying to draw a line between this guy and Phoenix, whose Japanese name is "Ryuuichi Naruhodou").
  • Public-Domain Character: Sherlock Holmes appears in the game, along with a girl called Iris Watson, and the real Watson is the victim of the first case.
  • Recycled In SPACE: It's Ace Attorney during Meiji Era Japan, in the first case, before becoming Ace Attorney in Victorian London.
  • Sequel Hook: A lot of them. The game has a lot of unresolved plot points and Foreshadowing, which is quite unusual for an AA game, and the writer of the game has even stated that they do, in fact, plan to make this a series.
  • Sherlock Scan: Holmes retains his nigh-supernatural deductive abilities, but in an added twist, he is less than concerned about whether what he deduces is actually true. It falls to Naruhodou to consider the evidence and decide whether his deductions hold weight.
  • Shout-Out:
    • Sherlock's dog design in Dog Gyakuten Saiban looks like a reference to Sherlock Hound.
    • The game itself is filled with reference to Sherlock Holmes canon, most notable in case 2 with the similar setup to The adventures of the Speckled Band story. A full list of the many references can be seen Here .
    • The omnibus in the third case is called the "Phoenix Wright Omnibus", which is a reference to the English name of Ryuunosuke's descendant, and main character of the main series.
  • Spiritual Successor: To Professor Layton vs. Ace Attorney, in that the game again features a defense attorney and his female assistant going to England and teaming up with an English gentleman and his young assistant. Naruhodou can cross examine multiple witness at once, just like that game. Even the box art is similar.
  • Translation Convention: It's presented as Japanese, but from case 2 and onward (barring some exceptions like the meeting with Souseki) the characters are speaking English.
  • Unexpected Character: Who would have guessed that Sherlock Holmes would appear in an Ace Attorney spinoff?
  • Wham Episode: Case 3. The trial ends with a Not Guilty due to lack of evidence and without finding a killer. But by that point it's heavily implied the defendant is the killer and he tampered with the omnibus/crime scene, however neither Barok nor Ryuunosuke is able to prove it. And then the case ends with the omnibus burning with somebody inside.
  • Wham Line: The ending of Case 5, when the characters are wondering about the contents of the state secret Morse code message: "A... SO...U...GI..."
