AsoRyuu

AsoRyuu is the slash ship between Kazuma Asougi and Ryuunosuke Naruhodou from the Ace Attorney fandom.

The Adventure of the Great Departure
In the actual case itself, it's revealed that the two were both at a 'high class establishment' restaurant, talking about Asougi and his government-funded trip to Britain to study the law.

The case's crime involved Naruhodou being framed for a murder that he didn't commit. Asougi took up his defense, albeit only three days after Naruhodou was arrested and had to quickly notify the change of attorney. During the prologue, a bailiff calls Naruhodou a murderer but was quickly shut up by Asougi, telling the bailiff that he should "stem the flow of garbage coming from his mouth" and that he had no rights to call Naruhodou a murderer, since he hasn't been proven guilty. After the bailiff backs off, Asougi tells Naruhodou that he believes in him. Naruhodou's inner monologue about Asougi - which he tends to blurt out verbally, calls Kazuma his best friend and that despite being the same age and same university year, Naruhodou thinks that they're completely different.

"This is my best friend, Kazuma Asougi. He's a second year student just like me. But to be frank, he and I are worlds apart. He's the pride and joy of our university."

- Naruhodou

But soon things take a sharp turn when Asougi's mentor, Mikotoba asks him if he's Asougi's best friend and then tells him that Asougi must not stand in today's trial. Telling him that Asougi's trip to Britain would be cancelled if he loses the trial today, Naruhodou reacts in shock and wonders why Asougi would take the risk to defend him. When the trial finally started, Naruhodou acted as his own defense attorney, much to Asougi's dismay.

"I'm disappointed. You think that, if I was your attorney, we would lose this trial."

- Asougi to Naruhodou

"N-No! Absolutely not. But.. If there was even a chance that you'd.. because of me.."

- Naruhodou to Asougi

Throughout the trial, Asougi stands by his side and acts as his aid. All the while displaying the close friendship between the two, with the frequent sarcastic jokes that Asougi make about Naruhodou such as if Naruhodou made another mistake in front of the court and embarrass him, Asougi would pull out his katana and "slice his head off" in a threatening joking manner. This behavior present throughout the entire trial - whether or not the player gets them wrong so that it demonstrates their strong, best-friend relationship.

Nearing the end of the trial, when the true culprit revealed themselves in court, the leading prosecutor says that he's been outwitted by an amateur student. Asougi then spoke up, telling the prosecutor: "The prideful men of old will be toppled by the younger generation. A hundred generations may pass, but your descendants will never rival those of this man." referring to Ryuunosuke & Phoenix. Naruhodou's final verdict was Not Guilty, and the first one to congratulate him in the court lobby was none other than his best friend, with Naruhodou thanking Asougi. Later on, Naruhodou tells his best friend, Asougi that he would be the greatest attorney in the world. Asougi soon shuts him down, telling him that maybe Naruhodou was the one meant to be an attorney all along. Not long later, Asougi tells him that he has a heartfelt request for him, but is quickly interrupted.

The Adventure Of The Unbreakable Speckled Band
Asougi sneaks in Naruhodou with him to the ship that he's taking to Britain, using a large suitcase and hid his best friend as a stowaway. What he didn't know was, he would soon be accused of taking Asougi's life while hiding in the very same cabin as his best friend.

Fanon
This ship is the most popular ship in Dai Gyakuten Saiban, although due to Dai Gyakuten Saiban / The Great Ace Attorney not having a official localization right now, the fanbase & fandom is quite smaller compared to the main Ace Attorney line due to the game only being exclusive to Japan. The English translations are from the fan-translation made by Scarlet Study and a mix of the DGS2 Youtube Sub playthrough.

It has the most content out of any DGS ship. Many people compare the two to NaruMitsu, due to their similarities.
