## Story

The Armed Detective Agency is a well-known agency with a very good reputation for their good deeds and cases. Ogai Mori, the ADA's president, decided to accept the offer of alliance with the Guild, and with that, the two groups have formed a stronger and greater organization. Ryunosuke Akutagawa would now accompany the mission with his sister, Gin Akutagawa, his best friend, Ichiyo Higuchi, his mentor, Chuya Nakahara and his current partner, Nobuko Sasaki. Little did the ADA know that the infamous Port Mafia decided to make their lives miserable to get what they wanted: The Book.

## The Armed Detective Agency

### Ryūnosuke Akutagawa

The protagonist of the Roleswap AU. He and his sister were found and taken to the ADA by Dazai after he saved them from gangsters, then became his mentee, having as a second mentor Chuya Nakahara. Nowadays, Chuya and Nobuko train him.

His outfit consists of a dark grey coat with a white scarf over it and a black shirt underneath both. His pants are black, with a silver belt wraped around his waist, black loafers with white ankle-length socks.

### Chūya Nakahara

The main deuteragonist of the RSAU. He's the mentor of Ryūnosuke Akutagawa and the strongest member of the ADA. After meeting Dazai and Odasaku, Chūya felt inspired to join the detectives, to both give himself a better life and maybe make amends for his past errors.

### Nobuko Sasaki

The second deuteragonist of the RSAU. She was a follower of the Azure Investigator together with his old agency, that was destroyed by the Port Mafia. She now works as a detective at the ADA with Chūya as her main partner.

### Gin Akutagawa

The main tritagonist of the RSAU. Instead of being trained by Dazai, she was trained by Ryūrō Hirotsu alongside Michizō Tachihara.

### Ichiyō Higuchi

The second tritagonist of the RSAU. She works alongside the Akutagawa siblings on missions and is known for her loyalty to the ADA. She has a silent crush on Ryūnosuke.

### Michizō Tachihara

A member of the Armed Detective Agency that trained under Hirotsu with Gin and works as a spy. Due to his spying missions, he has very few appearances at the ADA.

### Ōgai Mori

The president of the Armed Detective Agency and the former mentor of Nakahara, Dazai and Odasaku. When offered the alliance with the Guild, he agreed for the need of money.

### Odasaku

A former member of the Armed Detective Agency and the former best friend of Dazai and Ango, his death being an impactant and important moment for the story's ongoing plot.

## The Guild

### Edgar Allan Poe

The well-known greatest detective in the world that currently has found his biggest and most difficult challenge ever: catching Ranpo Edogawa. He helps Chuuya and Nobuko on some of their missions, but currently focuses on finding evidence or any way possible to capture Ranpo.

## Port Mafia

### Leader

#### Yukichi Fukuzawa

The boss of the Port Mafia and one of the major antagonists of the RSAU. He took care of Ranpo and raised him to be his successor, even when he wished to be a detective and get away from the crimes.

### Executives

#### Ranpo Edogawa

The oldest executives of the Port Mafia, one of the major antagonists and a serial killer that has never been caught nor revealed to the public, until he revealed himself to Poe. He's part of the mafia's most known trio, the Three Blacks (三黒 *Sankoku*). He's a big piece in the story of the Port Mafia, as he's responsible for bringing in Dazai and Kunikida, and being their former mentor.

Ranpo is know for being childish, carefree, and braggy about what he takes delight in, such as his skills on murdering and putting the blame on someone else successfully. He often teases his comrades, and his biggest target at the moment is Poe, the detective he had taken a lot of interest in lately. He uses of his great intelligence - which he believes is an ability called: Super Deduction; - to create a murder on the scene and put enough proof against someone based on how the scenery is plotted on his head.

#### Doppo Kunikida

An executive of the Port Mafia and a major antagonist of the RSAU. He's one of the main mentors of the Nighthawk Star assault group as well as the second member of the Three Blacks.

Formely known as the Hunter King, Kunikida is ruthless and very serious about his role in the mafia, and despises anything that could take away the "stability" the mafia has when it comes to function. He keeps his set of ideals, but as the years went by and his mindset slowly formed and altered itself thanks to the mafia's influence, those ideals begun to change, although most of them are still the same as the ones he had in the past. Despite denying, he holds a grudge against the detective Nobuko Sasaki, due to her connection with the Azure Detective.

He's very skilled with explosions and bombs, as well as covering up murders into suicides, like he did with the Azure Detective. He led the Azure Genocide, after hearing of the possibility that the Azure Detective was still alive from the news.

#### Osamu Dazai

An executive of the Port Mafia and a major antagonist of the RSAU. He brought Atsushi and Kyōka to the Port Mafia and mentors them and the other Nighthawk Star members with Kunikida. He's the third and final member of the Three Blacks.

### Nighthawk Star

The Nighthawk Star is the assault group that replaces the Black Lizard of the original Port Mafia.

#### Kenji Miyazawa

The leader of the Nighthawk Stars. He became the leader after beating all of his teammates in the challenges Ranpo gave them. He participates in the mafia's reunions with the executives to represent his group.

#### Jun'ichirō Tanizaki

A member of the Nighthawk Stars, the one to announce the group whenever they arrive to a mission and/or to prepare the surprise attacks thanks to his ability, Light Show.

#### Naomi Tanizaki

A member of the Nighthawk Stars, rarely in many close combat and mostly with a shotgun at a high distance.

#### Atsushi Nakajima

A member of the Nighthawk Stars, also known as the most brutal and cruel out of all the members, the most feared one of encountering. His reputation comes from his ruthlessness and brutality.

After enduring the abuse from his childhood orphanage for years, Atsushi fled from the orphanage a few months at the age of 16, still unaware of being an ability user. A few weeks before he turned 17, he lost control of his ability once again and went on a rampage, bumping into Kunikida and Dazai on his tiger form. After Dazai nullified his ability, he was brought to the Port Mafia, then convinced to join. Since then, his ability got under control thanks to the boss's All Men Are Equal ability. Under Kunikida and Dazai's suggestion, he burned down the orphanage he used to live.

With the creation of the Nighthawk Stars, an ability competition made by Ranpo would happen to settle the leader of the assault group, but Atsushi refused to participate since he didn't view himself worthy of being a leader. He became obsessed with beating Akutagawa, especially after figuring out that Dazai, for some reason, had a liking for him. After a while, he started to fight with an axe made by an ability.

His outfit consists of a black sleeveless jacket with a fur hood over a white long-sleeve shirt, the fur being white with black stripes, a pair of black pants cut to his shins with a black belt wrapped around his waist. On his feet he wears a pair of black ankle length boots. His jacket ended up sleeveless thanks to one of the orphans that tried to fight him while Atsushi wrecked everything down.

#### Kyōka Izumi

The latest member of the assault group. Although not the most cruel or brutal one, she's the strongest one out of the five, and with Nakajima's trainning, she's slowly letting go of her fear of using her ability.

Kyouka was tired of Akutagawa taking advantage of her ability and his mistreatment of her. While roaming the streets, she bumped into Atsushi, which she didn't recognise due to his hood hiding his face. He managed to convince her to join the mafia, at first using her as a spy, but after Akutagawa's first capture, she left the agency for good. She was put under Atsushi's trainning, and thanks to Fukuzawa's ability, she manages to use her ability freely. She can fight with a katana too, using Demon Snow to go for attacks she's sure she can't handle, nor get through.

In the beginning, Kyouka's outfit was just like the original. After joining the mafia, she was gifted by Atsushi and Kenji with a new outfit and accessories: currant red with patterns of snow on the bottom and the sleeves, with a blue datejime. She wears long white socks with black sandals. On her wrists there are golden cuff bracelets, and on her neck there's a necklace with a snow pendant.

### Other Members

#### Akiko Yosano

The mafia's doctor. She mostly stays inside of the headquarters, but she does go out for missions as well.

## Others

### Azure Detective

The Azure Detective was a detective and president of the Blue Investigator Org. He was Nobuko Sasaki's lover, an ally of the Armed Detective Agency and the self-declared rival of Kunikida that swore to capture him at all costs. He was known for his great thoughts on justice and his big obsession with colour shades, especially blue and colours that came from blue, like purple and green.

He believed Kunikida's justice was flawed, especially because Kunikida has never killed any criminals, but destroyed property, harmed innocents (on accident or not, he didn't care) and acted against the law, acting as the judge of who should and should not be arrested. He thought of Kunikida as an arrogant kid with a god-like mentality. Later on, he discovered of Kunikida's identity thanks to Nobuko fake-dating him and investigating him on secret for Azure. Their confront begun with Azure cornering Kunikida and both faces being revealed, Azure declaring his victory. Kunikida shot him, instantly killing him.

## AU Extras (With Spoilers)

* Odasaku and Dazai's new relationship was ***inspired*** by **Jujutsu Kaisen Suguru Geto and Satoru Gojo**.
* Instead of a jealous motive for Poe to try and beat Ranpo, this has become a detective-criminal chase to proclaim who was the best, all a game to Ranpo's entertainment.
* A new substance (very important one) will be added to this AU: a still-to-be-named inactivation bullet-injection. It was created by the Port Mafia, then recreated by the Special Division for Unusual Powers with the help of the Guild.
* Kunikida's previous nickname, "Hunter King", came from the shade of green from his notebook, once caught in a glimpse by a photo.
	+ Azure's obsession with shades was what made him refer to Kunikida as the Hunter King once he saw the photo, becoming a catchy nickname for the public as well.
* The name of the Nighthawk Star group came from the book with the same name written by the novelist Kenji Miyazawa.
