History YMMV / BungoStrayDogs

* ArcFatigue: The Decay of Angels saga became this, as many fans have grown irritated at each monthly chapter barely progressing the story along. It doesn't help that the main antagonist is considered far more boring and overpowered compared to previous ones.

* WhatAnIdiot: While the BadBoss of the technology company who [[spoiler:killed his own employee to steal and monetize the facial recognition technology that he developed]] had his company get hostile takeovered and his reputation ruined by Fitzgerald presenting his EngineeredPublicConfession in front of the court, he essentially got away with his crime; as Fitzgerald himself stated, none of the evidence he gathered was admissible and the boss would have walked away a free man. That is, until in [[VillainousBreakdown his rage at being ruined he decides to take a swing at Fitzgerald]] ''in front of the cops who are already there''. Not only does [[BullyingADragon Fitzgerald break a few of his bones while barely even trying]], he ensured he'd be spending some time in jail for assault as well, which would also give the police the chance to investigate the murder themselves because of the evidence they were provided and lock him up for good.
** Chuuya is known for making less than intelligent decisions.
*** Chuuya goes to mock Dazai after the latter is captured by the Port Mafia and breaks his chains to fight him, planning to kill his ex-partner. However, Dazai reveals he was CapturedOnPurpose and, unbeknownst to Chuuya, the executives were called to deliberate whether or not to execute him as he potentially has dirt on the Port Mafia that would be released upon his death, so Chuuya killing him then would be treason.\\
'''You'd expect:''' Chuuya owns a phone, so if it's on him he could call for help, have Dazai restrained again, explain he didn't receive the memo about the meeting and tell everyone what Dazai's plan was. If his phone isn't on him, he could incapacitate Dazai or block the exit to prevent him from escaping and use the opportunity to get help.\\
'''Instead:''' Chuuya gives Dazai access to classified intel, facilitates his escape and emasculates himself in exchange for having Dazai make it look like he wasn't involved and it was the ADA's doing. All the while, Chuuya never really considers that doing so is also treason and riskier than explaining he didn’t know about the meeting.
*** In the Fifteen arc, Dazai suddenly has Mori release the Sheep hostages in front of Chuuya, Shirase and Yuan. This relinquishes any leverage Dazai had over Chuuya and the latter would effectively be allowed to cease working with him and the Port Mafia.\\
'''You'd Expect:''' Chuuya would see Dazai is too dangerous to be around and cut ties with him in front of his fellow Sheep members, reaffirming his loyalty to them and ending any further dealings with Dazai or the Port Mafia.\\
'''Instead:''' Chuuya blows off Shirase and Yuan in favor of working with Dazai without much explanation, causing them to question his loyalty, eventually branding Chuuya a traitor and allowing Dazai to force him to join the Port Mafia.
*** Fyodor has Mori and Fukuzawa infected with a virus that will kill both if one does not die within two days, plunging the ADA and Port Mafia into all-out war. Chuuya is given control over the mafia while their leader is incapacitated.\\
'''You'd expect:''' With Fukuzawa and Dazai incapacitated giving the ADA only having six members on hand, and having the entire Port Mafia at his disposal, Chuuya could order a [[ZergRush massive attack without giving the ADA time to think]] and be done with the matter. Conversely, he could also negotiate with the ADA to combine resources to find the virus Ability user and avoid playing into Fyodor's hands.\\
'''Instead:''' Chuuya takes the Port Mafia to attack the ADA before they can formulate a plan, but stops and gives them the chance to hand over their leader, for some reason believing they'd actually do that. This allows the ADA enough time to make a plan and escape, leaving Tanizaki to cover their tracks. Tanizaki is then captured rather than killed, and brought to the base, enabling him to come within inches of murdering Mori.

** The anime's tendency of {{Padding}} by adapting prequel light novels started all the way in the first season, where the action of the Port Mafia arc was put on hold for a prequel adaptation in the middle of the series. The thing is, this was a NecessaryWeasel because the Mafia arc wasn't long enough to fill 12 episodes and something had to be put there. The second season started with another prequel adaptation; although it put the focus on a fan-favorite plot, a lot of fans were miffed about the way it caused a lot of the info of the Guild arc to be cut out. But by the time the third season came, adapting a prequel LN into ''three'' episodes, then expanding a couple backstory manga chapters into four more, leaving the Rats arc with only five episodes in which to tell its story, most were not pleased.

** The original Dark Era Light Novel had some {{Subtext}} between Oda and Gide. For example, [[https://nkhrchy.tumblr.com/post/147367058492/bsd-novel-dazai-osamu-and-the-dark-era-chapter when they first meet, Oda describes Gide as handsome]], [[https://nkhrchy.tumblr.com/post/147443082840/bsd-novel-dazai-osamu-and-the-dark-era-chapter Dazai proposes their wedding]], and the final duel is held at an old-fashoned ball room, and terminology like 'twirling half a turn' are used. On top of that, their Abilities work in such a way that they're completely synchronised. When the two come at a standstill (by ''holding hands'', if not in the conventional way), it's [[https://nkhrchy.tumblr.com/post/148247598657/bsd-novel-dazai-osamu-and-the-dark-era-chapter described]] as 'miraculous'. The anime [[AdaptedOut doesn't include most of it]], but interestingly leaves most of the subtext at the end in it. (as in that the fight is animated like a dance)

* DracoInLeatherPants: Much of Port Mafia gets this to some degree, but Akutagawa gets the special mention, as many fans are prone to completely ignoring that he's often a violent maniac and ''far'' from a typical rival character just so [[FoeYay they can ship him with Atsushi]].

** Many fans depict Chuuya and Dazai frequently calling each other 'Mackerel' and 'Slug' as insults despite the fact that these terms were their caller {{IDs}} in a single omake and have not been used otherwise. It's also widely accepted that the two often think about each other, and while Dazai has made comments to suggest this is the case for himself, Chuuya has never done anything to signify he does the same- even making remarks that would imply he avoids thinking about Dazai.

* FoeYay:

** Atsushi, who is most commonly paired with [[HairContrastDuo Kyouka]], [[{{Tsundere}} Lucy]], [[MentorShip Dazai]], and [[FoeYay Akutagawa]].
** Dazai also gets paired up with a lot of characters, [[HoYay usually with the male ones]], especially [[FoeYay Chuuya]], [[MentorShip Atsushi]], [[OddFriendship Kunikida]], [[WellDoneSonGuy Akutagawa]], and [[TragicBromance Odasaku]].

** Chuuya Nakahara. He was either born a normal boy was kidnapped from his family by the military before he even turned seven, and was experimented on to make him into an artificial Ability user with [[TriggerPhrase trigger phrases]] to control him, or a clone of the original Chuuya who underwent similar experiments with his entire personality being comprised of programming. After escaping, he joined a gang who treated him as a weapon until Dazai extorted him into joining the Port Mafia by tricking them into seeing Chuuya as a traitor and using them as hostages. After that, he dealt with numerous friends being killed by Verlaine, nearly had his personality overwritten by N, before having to throw away the answers to his past and later lost even more friends to the Dragon's Head Conflict. Aside from some anger issues, he grew up to be shockingly stable.

** Dazai. While there's a certain part of the fandom who absolutely loves his quirky character and thinks his past is interesting, they are often blamed for negating certain...other parts of his character. [[note]]If they do, that's for you to decide.[[/note]] Another part of the fandom doesn't think that he deserves sympathy and paints him as a ManipulativeBastard, a SociopathicHero or a very, very hardened practicer of ToughLove. They also accuse him of being abusive to Akutagawa, and by the time it is brought up we'll have to resort to the Administrivia/RuleOfCautiousEditingJudgment.

* UnintentionallyUnsympathetic: Originally, Dazai's sadness over Oda's death was seen as deeply tragic and upsetting, but after ''Storm Bringer'' was released, some fans came to see Dazai's reaction as hypocritical given that [[spoiler:it's implied he was responsible for leaking intel about Chuuya's friends to Verlaine, resulting in them being massacred, which is very similar to what Mori did to get Oda killed]].
** [[spoiler:Except that’s a misconception. Dazai only gave Verlaine information after Verlaine had killed Chuuya’s friends, and in any case Verlaine would have killed them regardless of Dazai’s involvement.]]

* HilariousInHindsight: Akutagawa [[Manga/JojosBizarreAdventureVentoAureo wouldn't be the only time]] Creator/KenshoOno voiced a teenaged mafioso with a FightingSpirit.

* UnintentionallyUnsympathetic: Originally, Dazai's sadness over Oda's death was seen as deeply tragic and upsetting, but after ''Storm Bringer'' was released, some fans came to see Dazai's reaction as hypocritical given that it's implied he was responsible for leaking intel about Chuuya's friends to Verlaine, resulting in them being massacred, which is very similar to what Mori did to get Oda killed.

* MemeticMutation:
** The creators have the tendency to market the series through releasing official art content, but special mention goes to BONES for paying [[HoYay special attention]] to Soukoku or the pairing of Dazai/Chuuya. [[http://bungo-stray-dogs.jp/images/top/main_movi.jpg When the very first promotional poster for the upcoming movie was released]], it's no wonder that the fandom starts claiming that [[ShipperOnDeck BONES]] is the ultimate shipper of Soukoku.

** [[SmugSnake Pushkin]] from the Wharf Rats is considered one of the most disapointing villains the series has ever produced. The series hyped him up as the source of the incurable poison as well as a criminal mastermind only to reveal that he was a DirtyCoward with zero fighting ability who ran at the first sign of trouble and was outsmarted pitifully easily. Since fans of the series are used to charismatic, stylish villains who can match the protagonists in wits as well as strength, many were outright infuriated that the person causing the race against time in the arc turned out to be this pathetic loser.

** In ''Storm Bringer'', Dazai and Chuuya know Corruption is the only way to defeat Guivre, but instead of just letting him go off, Dazai pulls Chuuya aside and explains that if he uses it, he will be throwing away the one answers to the question that's troubled him his entire life. Dazai then allows Chuuya time to think it over and has the courtesy to give him space, though the important part is that this isn’t an attempt at manipulating him, Dazai is ''genuinely giving Chuuya a choice'', and starts coming up with a backup plan in case his partner refuses. Chuuya even remarks that Dazai is [[OOCIsSeriousBusiness acting weird]], and he's described as having a very serious look Chuuya hadn’t seen before. Despite their hatred for each other, it's oddly touching to see Dazai not take the opportunity to screw Chuuya over and instead be a decent person.

** Dazai: A common interpretation of Dazai is that of a womanizer who sleeps around. He is seen flirting and called out for his 'unsavory actions' numerous times throughout the manga and light novels. However, many others do not take this at face value due to his trademark [[ManipulativeBastard manipulative behavior]] and use of {{Obfuscating Stupidity}}. It's worth considering that the people who accuse him of these behaviors (Kunikida and Chuuya), while not liars, are very susceptible to his manipulation and teasing. At the very least, the flirtatious behavior appears to be purposely dialed up to 11 as another mask. When Dazai is seen flirting with women on screen, it is always done with an ulterior motive- at least half the time with something violent happening to the woman (see Higuchi or Azure Messenger). It is likely that he does not or does not need to follow through with the flirtations to get his desired results. As quoted in the Entrance Exam light novel: “And from my experience, it takes only a smile and some kindness to get a woman swooning over you when she’s fallen on hard times.” He notably does not sleep with Sasaki when given the opportunity.

** Dazai: A common interpretation of Dazai is that of a playboy who sleeps around. The major cause of this interpretation comes from Chapter 31 when Chuuya threatens to reveal Dazai's address to numerous women. Addtionally, Dazai is seen flirting with three different women through the course of the story: the waitress, the nurse at his hospital, and a woman from the "Azure Messenger". He has also said that he 'likes all women'. However, many others view these traits less as legitimate flirting and more as another side of his [[ManipulativeBastard manipulative behavior]]. It's worth considering that Chuuya's threat is oddly worded, that Dazai is using all three women for different reasons: the waitress to get free food, the nurse to get back his phone, and the Azure Messenger woman for information. He's directly responsible for [[spoiler:Azure woman's death]] and he uses his flirty behavior to play up his {{Obfuscating Stupidity}} with Kunikida. Dazai has admitted to feeling 'not human' and seems to purposely exaggerate a goofy persona to put others at ease. Although not as popular, it is not uncommon that many fans have seen Dazai as a more asexual character.
*** It's also worth pointing out that Dazai's flirty behavior, like his suicidal tendencies, are a [[HistoricalInJoke reference to real-life Dazai Osamu's relationships.]] That doesn't mean for a one-to-one canonization, though.

* {{Fanon}}: Many fans depict Chuuya and Dazai frequently calling each other 'Mackerel' and 'Slug' as insults despite the fact that these terms were their caller {{IDs}} in a single omake and have not been used otherwise. It's also widely accepted that the two often think about each other, and while Dazai has made comments to suggest this is the case for himself, Chuuya has never done anything to signify he does the same- even making remarks that would imply he avoids thinking about Dazai.

* DesignatedHero: While it is a stated theme that the Armed Detective Agency are NotSoDifferent from the enemies they fight, and not all of them fall under this classification, there are still a couple that seem to only be heroes because they are fighting for the heroic side. Most notably, Ranpo, who is an [[SmallNameBigEgo overconfident, arrogant braggart]] who only takes jobs for the protagonists' side because [[ItAmusedMe it amuses him]]. Yosano also falls under this, as a TortureTechnician who just happens to be TheMedic as well. Even [[spoiler:Dazai]] may be considered this; while he is TheAtoner, he [[spoiler:has a bloodstained past to rival and possibly surpass Akutagawa's.]] Tanizaki finally addresses this in the Rats arc, stating that the only way the Agency can protect people is by hurting yet other people, and they just have to deal with it.

** Even Mori and Fukuzawa get this from time to time, fans saying they are the progenitors of 'Soukoku'.

** Atsushi having been kicked out of his orphanage has became one to some people due the amount of times that the series (especially the anime) reminds the viewers again and again that... [[ExactlyWhatItSaysOnTheTin Atsushi was kicked out of his orphanage]].

* TheScrappy:
** Aya from the ''Walking Alone (Hitori Ayumu)'' OVA, an annoying TagalongKid who basically bullies Kunikida into taking her along with him with a [[AccidentalPervert Mistaken For Pervert]] accusation, then promptly gets herself [[DamselScrappy captured and used as a hostage]]. She, and the one-shot villain of that chapter/OVA have not made another appearance in the series, and practically no one wants to see her come back anyways.

* {{Wangst}}: Atsushi's frequent mental breakdowns over [[MemeticMutation getting kicked out of the orphanage]] can easily fall into this. Yes, he was treated terribly and has bad mental scars because of it, but it doesn't help that every time he seemingly gets over it and saves the day, [[ResetButton he falls right back into self-loathing as soon as the next arc starts]].

** Chuuya and Dazai is the most prominent example, being former partners turned enemies.

* UnintentionallyUnsympathetic: Originally, Dazai's sadness over Oda's death was seen as deeply tragic and upsetting, but after ''Storm Bringer'' was released, some fans came to see Dazai's reaction as hypocritical given that it's heavily implied he was responsible for leaking intel to Verlaine about Chuuya's friends to distract the assassin from taking out Mori, resulting in Chuuya's friends being massacred.

** Naomi can be this. Naysayers view her [=BroCon=] as sexual harassment/RapeAsComedy, while some think her brother consents to her behaviour.
** Interestingly, Dazai can also be this. While there's a certain part of the fandom who absolutely loves his quirky character and thinks his past is interesting, they are often blamed for negating certain...other parts of his character. [[note]]If they do, that's for you to decide.[[/note]] Another part of the fandom doesn't think that he deserves sympathy and paints him as a ManipulativeBastard, a SociopathicHero or a very, very hardened practicer of ToughLove. They also accuse him of being abusive to Akutagawa, and by the time it is brought up we'll have to resort to the Administrivia/RuleOfCautiousEditingJudgment.

** After learning the full story of her parents' deaths--namely that [[spoiler:Demon Snow had been her mother's Ability, transferred to Kyouka and ordered to protect her when her parents fell under the sway of an Ability that turned them into PeoplePuppets]]--there's a shot of Kyouka leaning up against the entity's side, finally accepting it as a manifestation of her parents' love. The fact that Kouyou went to the trouble of getting the relevant information into Kyouka's hands makes it doubly sweet.

** Aya from the ''Hitori Ayumu'' OVA, an annoying TagalongKid who basically bullies Kunikida into taking her along with him with a [[AccidentalPervert Mistaken For Pervert]] accusation, then promptly gets herself [[DamselScrappy captured and used as a hostage]]. She, and the one-shot villain of that chapter/OVA have not made another appearance in the series, and practically no one wants to see her come back anyways.
** While there is much debate between fans as to whether the Wharf Rats fail to live up to their predecessors in the Port Mafia and Guild or if they are unique and good villains in their own right, practically everyone agrees that [[SmugSnake Pushkin]] is one of the worst villains the series has ever produced. The series hyped him up as the source of the incurable poison as well as a criminal mastermind only to reveal that he was a DirtyCoward with zero fighting ability who ran at the first sign of trouble and was outsmarted pitifully easily. Since fans of the series are used to charismatic, stylish villains who can match the protagonists in wits as well as strength, many were outright infuriated that the person causing the race against time in the arc turned out to be this pathetic loser.

* [[TheyChangedItNowItSucks They Changed Him, Now It Sucks!]]: The characterization of Randou/Rimbaud was very differently in the anime than in the Novel. For example, in the Novel (that came first), he is actually apologizing during the fight and not at all revelling in it.
* TheyWastedAPerfectlyGoodCharacter: Arguably, Chuuya was an overall very poorly-planned character. His previous status as part of Double Black with Dazai could have yielded some interesting parallels with the new Double Black team, and his relation to Dazai could have provided more insight into a very enigmatic character. Unfortunately, Chuuya was given a massively overpowered Ability, making him incredibly difficult to use to advance the plot in any meaningful way, as it's easy for him to get rid of problems. On top of this, Chuuya was given a design to make him popular, which was a little too effective as he needs to be periodically inserted into the story to make fans happy. However, adding him to the story is difficult due to his aforementioned Ability, and because he's popular, Chuuya cannot be easily gotten rid of to remove the dead weight from the story. The only way he really can be utilized at all is in promotional materials and side stories that don't really effect the main storyline.
* ToughActToFollow: The Port Mafia and Guild are both hugely popular bad guys, so it wasn't a surprise that the Rats fell into this. While [[MagnificentBastard Dostoyevsky]] is well-liked, the rest of the Rats are considered poorly-developed or just plain unlikeable by the fanbase. (barring Mushitarou, who has an entire arc to himself detailing his past and motivations)
