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 number of Let's Plays of the game with English translations are currently in progress on YouTube. One can be found here; a second, of the first case only, can be found here. The latter has been cancelled.

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: Completely subverted for the first time in the series with case 4, as the crime is attempted murder. And even then it turned out to be an accident.
    • To put this into perspective: Turnabout Reclaimed, the first case in the series which the 'murder' turns out to be an accident, still involved a dead victim and a malicious intent (though the intended victim was something else), and was still initially a trial for murder. The Clouded Kokoro already starts out as an attempted murder, and the incident came about from a series of unfortunate coincidences rather than from an actual attempt of harming someone. Oh, and the victim lives in the end.

  • A Day in the Limelight: Some of the randst episodes the viewpoint is from Asougi and Barok.
  • 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.
  • Badass Cape: Barok van Zieks
  • Child Prodigy: Iris Watson is 10 years old...but still brings over the original Watson's medical doctorate, and since John Watson wasn't a Child Prodigy, this is also an Age Lift.
  • Completely Unnecessary Translator: Jezail didn't need one.
  • Deliberate Values Dissonance: Several characters are racist towards the Japanese, and this would have been fairly normal at the time the game is set.
  • Downloadable Content: DLC includes character designs, short episodes, music and voice clips.
  • Expy: Ryuunosuke Naruhodou looks like a mix of Phoenix and Apollo, might be on purpose though. With his hat on, he also bears a striking resemblance to Clay Terran.
  • First Episode Spoiler: John Watson is the victim of the first case.
  • Girlish Pigtails: Iris Watson has her hair braided into two curly pigtails with heart-shaped knots at the end.
  • Historical-Domain Character: Natsume Souseki as one of the defendants.
  • 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, it seems here all the case titles will 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 apparently the author of The Adventures of Sherlock Holmes in this universe.
  • Locked Room Mystery: Case 2
  • Martial Arts Headband: The headband Kazuma Asougi wears resembles one.
  • Meiji Restoration: The backdrop and context for Ryuunosuke and Susato's characters. Described as an age where defense attorneys are still carving a niche as a viable profession in Japanese society. Shifts to Victorian London after the first case.
  • 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 seems 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 .
  • 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.
    • The gameplay demo from Jump Festa '14 reveals the game will have multi-witness cross examinations, much like Prof. Layton vs. Ace Attorney.
    • Hell, even the box art is reminiscent of Professor Layton vs. Ace Attorney.
  • Sweet Tooth: Judging by the trailer, Susato appears to be one. "Chocolates, cookies, biscuits, egg pudding..."
  • Token Mini-Moe: Iris Watson.
  • Translation Convention: It's presented as japanese but from case 2 and onward 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 and Ryuunosuke is able to prove it. And then the case ends with the omnibus burning with somebody inside.
  • Yamato Nadeshiko: Susato Mikotoba, the assistant to Ryuunosuke, is a very clear-looking example of this. She's described as an ideal Japanese woman from the time period with a progressive way of thinking.
  • You Gotta Have Blue Hair: Iris Watson's hair is a strawberry shade of pink.
