Plot
After being kicked out of his orphanage, the young Atsushi Nakajima saves a detective named Osamu Dazai, believing he was drowning in the river while his actual intention was suicide. From Dazai, Atsushi learns he is a gifted with a supernatural ability capable of transforming him into a berserker white tiger. Dazai recruits him into the Agency he works for, the Armed Detective Agency, that handles crimes too dangerous for the police to handle. There, he meets many other ability users as they tackle various cases and events taking place in the city of Yokohama, a place teeming with individuals with Supernatural Abilities. Atsushi becomes the target of Dazai's former pupil Ryūnosuke Akutagawa, who is a member of the criminal organization run by Ōgai Mori known as the Port Mafia.Atsushi also rescues the young mafia member Kyōka Izumi upon learning she is being forced to kill.During Atsushi's fights against the mafia, he also meets Francis Scott Key Fitzgerald, the leader of an organisation named the Guild who placed the bounty on his head. Fitzgerald reveals there is a supernatural book (referred to as The Book) capable of changing reality linked with Atsushi, hence putting a bounty on the black market. Fitzgerald disregards any superficial damage the Guild might bring to Yokohama in exchange for the book, having an airship named "Moby Dick" destroy the city. However, he is nearly killed by Atsushi and Akutagawa once they join forces while Kyōka stops Moby Dick. Kyōka then joins the Agency.
A Russian man, known as Fyodor Dostoevsky sets up a fatal clash between the detectives and the mafia using a virus ability user from the group that he leads, Rats in the House of the Dead.Natsume Sōseki, who is the creator of the collaborative Tripartite Framework, stops the fight. While Atsushi and Akutagawa corner the virus' originator, Dazai manages to arrest Dostoevsky. Pages of The Book are later found by Dostoevsky's other group, the Decay of the Angel, which uses its powers to frame the Detective Agency for a murder case.Dazai is imprisoned for his past crimes and is placed in a cell near Dostoevsky while the government sends its military forces known as the Hunting Dogs to execute the members of the Agency. As the Agency faces defeat, they form an alliance with Fitzgerald and later the mafia. Across the multiple fights, it is revealed there is another person above Dostoevsky, the leader of the Decay of Angels is Ōchi Fukuchi, the leader of the Hunting Dogs.
The United Nations decides to release One Order, an ability weapon that can make the listeners of orders given through the device act as ordered. A young girl named Aya Koda takes Bram from Fukuchi to stop the vampires. As Fukuzawa manages to defeat Fukuchi, he is revealed to have wanted to rid the world of wars through his methods. Back in the prison Dazai and Fyodor were in, it is revealed that the latter's special ability is to take the body of whoever killed him; who in this case is Bram Stroker. This is shown when Bram's face tears open and Fyodor is there inside. Fydor then proceeds to create a singularity using the Sword which was previously imbedded in Bram's body and turning Fukichi into a God called Amenogozen. Atsushi manages to defeat Amenogozen and then manages to corner and kill Fyodor with help from the allies. Afterwards, the Detective Agency is forced to close, and Atsushi finds himself in another dimension when Kyoka gives him a page of the Book.
Development
After quitting his job as a salaryman, Kafka Asagiri became popular through his video "Yukkuri Youmu and the Really Scary Cthulhu Mythos" released on Nico Nico Douga.[7] The first episode was viewed about 1 million times, much to Asagiri's surprise.Four months after he uploaded the video, Asagiri was approached by the editor-in-chief of Monthly Shonen Ace to bring in three projects in two weeks.The Editorial department has also contacted him.[8]
The manga originated from Asagiri's idea to gather multiple famous late authors and poets and draw them as young adults and teenagers with supernatural powers.[9] He was inspired by Shūsaku Endō's story Ryūgaku.In particular, Osamu Dazai was used as a major character after reading his book No Longer Human; in the story, Dazai expresses his embarrassment involving his entire life which the author found relatable. Impressed with this work, Asagiri decided to make his own take on Osamu Dazai stand out among the readers. After Dazai, the next writer chosen to make a character that often accompanied Dazai was Atsushi Nakajima, the main character. However, he instead needed a third character who acts as an equal to Dazai. This led to the creation of Kunikida. Although Kunikida was hard to come up with, Asagiri did not have writer's block in general as he claims that writing backgrounds takes him between two or four days. He calls this process "mysterious". Kadokawa Shoten approached Asagiri with writing more content for the characters, which led to the production of light novels where the writer decided to explore Dazai's past.[10]
Among several supernatural elements seen in the series, Asagiri came up with one that everybody wants under the name "The Book". The magic nature of the book was based on Akira Toriyama's wish-granting items from the manga Dragon Ball. A major theme in the narrative of people overcoming themselves; as an example, Kyōka Izumi was written as an assassin who wants to escape from the work from the Port Mafia and instead becomes Atsushi's partner in the Detective Agency. While Kyōka is unable to leave her past behind, she tries to appeal to the readers with her new way of living which was written to be relatable. Villains are often written to be relatable despite their horrible actions too. Francis Scott Fitzgerald from the Guild plans to destroy Yokohama in his story arc but at the end and his next appearances, it is revealed his only desire was protecting his family. Sigma is also another villain written to be relatable though the author made him like that due to his "average" skills when compared to stronger antagonists. Ranpo Edogawa was one of the hardest characters to write due to his superior intelligence when compared with the rest of the characters but still felt that his role in the story would appeal more to the fans once he became more active.[11] As the series progressed, Asagiri reflected although the story is about the battle between justice and terrorism with the arrival of the Decay of Angels and Hunting Dogs, it was more specific about the side of justice and who is on the enemy side of evil.He wanted the reader to do whatever he wanted to do based on whether he was to be included on either side.[12]
Sango Harukawa provided Asagiri with designs that helped the writer to create the stories easier. Asagiri stated that the designs of Atsushi and Dazai were done to contrast each other although there were some revisions done in the making of the series.[13][14] The light novels were also written with the idea of having more books released per year.The lives of more writers inspired Asagiri, most notably the friendship of Osamu Dazai, Ango Sakaguchi and Sakunosuke Oda.[15] When it came to Sigma, Asagiri drew his own take on the design but it was instead altered by Harukawa.[11] In 2023, Asagiri expressed satisfaction with the large amount of other works based on his manga and expected there would be more products in the future.[12]

Reception
Manga
Bungo Stray Dogs was well received in Japan. The series also appeared in the Da Vinci magazine poll from Kadokawa Shoten,[58] while the franchise combined sold ¥1,878,804,092 in 2016.[59] By 2018, the series reached 6 million copies.[60] In 2022, the manga reached 10 million copies in print.[61][62] In 2024, the manga reached 16 million copies in print.[63]
It came in at 11th for the "Nationwide Bookstore Employees' Recommended Comics of 2014".[64] On TV Asahi's Manga Sōsenkyo 2021 poll, in which 150,000 people voted for their top 100 manga series, Bungo Stray Dogs ranked 64th.[65] Author Dan Brown was attracted by the manga when the author created a fictional version of himself to promote the story.Brown stated he was pleased with the result.[66]
Critical reception to the series has been positive. The Fandom Post said ever since its start the series has had potential to be an entertaining manga, citing the characterization of Atsushi and the power he has,[67] later leading to interesting mystery arcs when more characters from multiple parties become involved,[68] such as the reluctant alliance Atsushi and his rival Akutagawa form to defeat another group.[69] The artwork was praised by UK Anime Network for how detailed are fight scenes while also praising the balance between dark and light plot storylines.Nevertheless, he found a common commentary within fans that the series suffers from a slow pace.[70] While liking the Kunikida subplot, Anime News Network criticized the emotional focus on Atsushi's emotional state in the manga as he often grieves about his background, as well as the way he deals with his emotions when his torturer passes away.[71][72]
J. Laturnas from University of British Columbia noticed that Dazai's characterization in Bungo Stray Dogs and Bungō and Alchemist helped to revitalize the original author's works. "Of course, the character named ‘Dazai Osamu’ is not the person himself," Asagiri laughs, "the most important thing was to make [the author-characters] interesting in a manga-like way." The Dazai in Bungō Stray Dogs is not a characterification of the author himself but of the author's star text: an abstract representation of “Dazai” and his literature in popular imagination. Likewise, Dazai's character is heavily inspired by No Longer Human and its protagonist, Ōba Yōzō, with a few references to the historical author's life, personality, and preferences. In regards to his past, he has no desires nor a reason to live and has suffered in solitude for most of his life. Thus, he resorts to playing the role of a clown and hiding most of his true emotions with suicidal antics. However, Dazai's character has still made significant progress towards the fulfilment of his friend Oda's dying wish for him to turn to the light, and uses his inner darkness and past experiences to serve as a guiding light.[73]

Otaku USA stated that, while Atsushi becomes a hero of the story, he is overshadowed by others whose characters the reviewer found more interesting.[88]Anime News Network felt that, while initially weak, Atsushi could become, little-by-little, a stronger person, due to the way Dazai guides him.[89] The Fandom Post saw Atsushi as the readers' guide to the series since he was a newcomer whose introduction to the detective agency made it known to the readers as well.His final fight against Akutagawa in the first season received a positive response.[90] There parallels between Atsushi and Kyoka were also praised due to how they bond, making the protagonist look more charming in the process.[91][92][93] Anime News Network appreciated the new bond he formed with former Guild member Lucy Maud Montgomery; the reviewer expected that either a formal romance would develop between these two characters or a love triangle alongside Kyoka, who also had a strong bond with Atsushi.As a result, the writer said the story would benefit from this type of subplot since Bungo Stray Dogs rarely contained romance.[94][95] When season two ended, The Fandom Post saw Atsushi's team up with Akutagawa as one of the best sequences in the series, which explored how the two characters felt during their interactions and production values made the fight more entertaining.[96] Meanwhile, Anime News Network enjoyed the portrayal of Atsushi's thoughts regarding his abusive caretaker since he had a serious attitude when he talked about them while interacting with Akutagawa, feeling this made Atsushi appealing.[97]
The flashback episodes from season two and three were the subject of positive response. Manga.Tokyo highly praised the relationship between the teenage Dazai and Odasaku since it shows the impact Odasaku had on the Dazai's characterization and growth as a person which contrasted with his regular personality,[98] while UK Anime Network felt it made the cast look more rounded in the general due to the multiple use literal characters based on real life alongside Ango.[99] Dazai's debut in the anime's third season earned praise from Manga.Tokyo for once again exploring his teenage years where his relationship with Chuuya Nakahara is revealed in the form of flashback episodes.The site noted that the debut explores the relationship between Dazai and Mori and how Mori sees himself in Dazai.[100] Anime News Network noted how dark this incarnation of Dazai is as he does not appear to care for other people and instead ponders the idea of killing himself in contrast to his cheerful persona from the regular series.[101]
