Our attorney finds himself unconscious in the courthouse lobby, and he's unable to recall anything! How will he save his client?

A Kurain village treasure exhibit is set to be held at the Lordly Tailor, the biggest department store in the city. But the sacred urn is stolen by none other than Mask DeMasque, renowned phantom thief!

The trial of Mask DeMasque for stealing the Kurain's village urn begins, with plenty of twists and turns in the story!

The client was at the scene of a murder when the crime occurred, and our defense attorney was the one who proved that in court! How can he get out of this mess?

With the murder trial beginning, our attorney must unravel the elaborate scheme surrounding the two incidents that occurred simultaneously and unmask the true killer.

Hearing the radio at a restaurant brings back memories of when music helped connect two distant friends.

Phoenix is surprised to hear that Maggey was found guilty in a murder trial that he himself was reportedly the defense attorney for. Realising that someone must have impersonated him, Phoenix looks into Maggey's case for a retrial, learning that Maggey witnessed a man killing the programmer Glen Elg with poison while working at the Trés Bien restaurant. So Maggey becomes accused of the murder as no one else reported seeing the man in question.

Phoenix and Maya learn that Armstrong owes money to a loan shark. Our heroes visit the office of the loan shark in question and the one who impersonated Phoenix, Furio Tigre. Afterwards, the pair hear from Gumshoe about Tigre's relationship with Viola Cadaverini, the granddaughter of a mob boss, as well how Elg had planned to pay off a debt he owed to Tigre with a computer virus had he not won the lottery.

Following a hole-filled testimony by Armstrong, Phoenix suspects that the murder Kudo witnessed was actually a reenactment which took place after the actual murder. After Armstrong explains he was forced to hide Elg's body and participate in the reenactment, Tigre is brought in to testify. Phoenix deduces that Tigre wanted Elg's virus to pay off Viola's medical bills, but when Elg won the lottery, eliminating the need to sell it to him, Tigre killed him and stole the virus before having Viola help him reenact the scene to frame Maggey. Lacking the evidence needed to seal a victory, Phoenix bluffs about some evidence brought in by Gumshoe to trick Tigre into correcting him and revealing his own guilt, resulting in Maggey being declared innocent.

A dream train ride takes a drastic turn when it's hijacked by a fugitive demanding a retrial.

The trial is underway, and the evidence mounts against the defendant, but it is interrupted by a blood-curdling scream and the discovery of a corpse.

Phoenix discover that the train's cars were actually rearranged just before the takeover, and this leads him to deduce that the corpse from Car 1 was a fake and the real Gale was killed in Car 3 during dinnertime, suspecting of Turnbull. Edgeworth verifies Turnbull's involvement in the trial, having obtained the truth from the committee, and Turnbull reveals that he killed Gale when he attempted to blackmail him and was forced to create the fake scenario when the takeover occurred. After Richman is declared not guilty, he chooses to die alone by setting off a time bomb in the dining car, but the committee offers him a fair retrial, convincing him to safely join the others before the bomb goes off.

Five years ago, Phoenix is accused for the murder of Doug Swallow. Mia defends Phoenix in court, where Payne suggests Phoenix had bad blood with Swallow over his then girlfriend Dahlia Hawthorne and pushed him into a severed electrical cable. Payne then brings in Dahlia to testify about the murder, but Mia deduces that this case is linked to an incident eight months ago, in which a lawyer was poisoned and Dahlia was the prime suspect. Upon learning that this was also the day Phoenix and Dahlia met, Mia suspects that the container used for the poison was a pendant Phoenix received from Dahlia that day. Urged by Mia to give the proper truth, Phoenix reveals that on the day of the murder, Swallow told him that Dahlia had stolen poison both eight months ago and the night before. From this, Mia deduces that Dahlia had originally intended to kill Phoenix to retrieve her pendant by poisoning his cold medicine, finally proving Dahlia's guilt and Phoenix's innocence.

After accidentally breaking a precious seashell that she received from Maya, Pearl asks Phoenix to help her search for an identical looking shell without Maya knowing. As Phoenix helps her find the beach where it originally came from, Pearl recalls how Maya went against Morgan's authority to bring her to see the beach, giving her the shell as a reminder. While visiting the beach's shrine, Phoenix and Pearl run into Maya and learn that the shell she gave Pearl was something she received from Mia when she first took her to the beach, leading Pearl to feel even more guilty. Upon discovering that the shell was actually a bowl from a ramen shop, Phoenix offers Pearl one as a replacement, but Pearl decides to stick with the one she has due to the memories it contains.

One year prior to her first meeting with Phoenix, Mia takes on her first client; a death row convict named Terry Fawles who is accused of murdering policewoman Valerie Hawthorne, with the assistance of her senior, Diego Armando.

After Dahlia's attempt to feign ignorance only incriminates her further, Mia has Fawles testify about the incident from five years ago.

Phoenix, Maya, and Pearl go to Hazakura Temple for Maya's training, where they meet children's book author Elise Deauxnim and nuns Bikini and Iris, along with Larry, who is studying as Elise's apprentice.

While investigating the shrine, Edgeworth listens to Bikini's account of Elise's murder, learning that Pearl has gone missing, before meeting up with Larry, who appears to be hiding something he saw on the night.

During his testimony, Larry presents a sketch he drew of what he saw on the night of the murder, allegedly depicting Iris flying over the flaming bridge.

While Iris is brought in to work on the trick lock, Phoenix finds a charred letter instructing someone to channel someone, along with a talisman Elise was carrying.

As court resumes with Phoenix once again against Godot, Iris suddenly claims that she helped cover up Elise's murder after she was allegedly killed by Maya in self-defense. However, her testimony proves false with the reveal of real murder weapon and Elise's identity as Misty.

Dahlia reveals she had plotted with Morgan to murder Maya and make Pearl head of the Kurain family so she could get revenge against Mia.

Noticing that Maya was able to identify the true culprit in the dark, Phoenix deduces that the killer is Godot, whose red visor not only glows in the dark but also leaves him unable to see anything red, including the bloody message incriminating Maya.
