WHAT.

There is nothing in the light novel.

Plus the Seven traitors might be this

🔸 🔶 🔶 🐑 🔶 🔶 🔸

3 + Chuuya + 3 = 7

[rashoumon-homo]

Been thinking about how the next episode is a total mystery to both manga readers and anime-only fans. From a promotional standpoint, this is a perfect opportunity for them to do something wildly shocking. As far as I know, a situation like this hasn’t come up before in the fandom. It makes me think that they’re preparing for something huge that they didn’t want half the fandom to know before the other half.

And my delusional ass wants it to be Soukoku canon. Like wasn’t there an interview or something about how this season will show the true depth of Chuuya and Dazai’s relationship? And that ship is a really big part of the fandom- it would rock us to the core if it became canon.

I know there’s like no chance logically, but man wouldn’t that be cool. They’ve set themselves up for a reveal of that caliber. This is the perfect time for them to follow through.

[mayoi-inu]

This is getting interesting :)

So the two blades are named after Ueda's ability.

雨月物語　Ugetsu monogatari, Tales of rain (雨) and moon (月)

But also one of them manipulates space time and the other, the one for the moon, manipulates life force.

The moon is related to Atsushi's ability beast under the moon. His ability is regeneration.

And the rain is related to Akutagawa's ability! Have you read Rashoumon? Rain and cloth.

Ahahhhhahahahaha

i don’t think amenogozen is truly killing people

remember how teruko melted and all that was left was her hd uniform?

the hunting dogs took her in, gave her a home, gave her a real purpose. that uniform represents who she is.

but when kunikida melted, his clothes went with him, and what was left behind instead?

his notebook. his ideals. his ideals represent who he is.

the thing that represents who they are is left behind.

i know that doesn’t really explain anything, but it’s at least enough for me to cause some doubt

[sorcerersandskillusers]

Spoilers for Chapter 114.5

This confirms that Dazai is literally the only person who can kill Fyodor since he would nullify the possession. Which makes the "You can't kill me line" way funnier because Fyodor was really thinking

"please for the love of god do not be the one to kill me"

[featherstorm2004]

Ok but the implication that Fyodor inherits the personality traits of the people who kill him is extremely messed up when you think about it. And considering how old he is it's very likely his original personality has been completely taken over by this point, honestly I wouldn't be surprised if Fyodor doesn't actually have a grand master plan but is instead working with a hodgepodge of half baked ideas culminated by his past vessels over the centuries.

Especially when you consider that these new desirers seem to effect him strongly, with him not giving two shits about Aya until he took over Bram and now suddenly he's yandere levels obsessed with her.

[justcallmesakira]

I love how the bsd fandom was celebrating chuuyas birthday being happy, joyful, a bit of angsty JUST yesterday and then fyodor just comes to ruin the party like that one auntie that no one of the family likes.

There’s something so fascinating about the dynamic between Dazai and Ranpo that rarely gets the attention it deserves.

Their relationship isn’t built on the same kind of camaraderie we see with Dazai and Chuuya or Ranpo and Fukuzawa. Instead, it exists in this weird, nebulous space of mutual brilliance, calculated detachment, and an unspoken understanding that neither of them really need to try around the other.

Both of them are geniuses, but in very different ways. Ranpo’s intelligence is so deeply ingrained in his identity that he doesn’t even consider it a “gift”—it’s just who he is. His self-confidence is absolute, bordering on arrogance, because he knows he’s the smartest person in the room. He doesn’t second-guess himself because, in his eyes, there’s simply no reason to.

Dazai, on the other hand, is an entirely different breed of genius. His intelligence is adaptive, shaped by his time in the Mafia, honed for manipulation, survival, and deception. He’s brilliant, yes, but he’s also deeply aware of his own mind—sometimes to the point where he actively tries to outmaneuver himself. Where Ranpo is unwavering in his certainty, Dazai constantly tests and plays with possibilities, viewing life as a game where he’s always five steps ahead.

That’s where their dynamic gets interesting. 🤨 👇🏽

1. They Don’t Need to Prove Themselves to Each Other

Dazai is someone who loves testing people. He provokes them, plays mind games, and watches their reactions for fun. He enjoys unraveling people, poking at their insecurities, seeing what makes them tick. And yet, with Ranpo? There’s none of that. Why? Because Ranpo sees through him. Where most people get caught up in Dazai’s theatrics, Ranpo just doesn’t care. He can see the games Dazai plays, but they don’t interest him because, in his mind, he’s already won before the game even began. This puts them in a strange but mutual space of respect—Dazai doesn’t bother trying to manipulate Ranpo, and Ranpo doesn’t feel the need to prove that he’s smarter. It’s one of the rare relationships where Dazai can just exist without putting on an act.

2. Dazai as the Observer, Ranpo as the Unshakable Constant

Dazai is constantly watching. It’s in his nature. He studies people, picks them apart, and predicts their next moves before they even think to make them. Ranpo? Ranpo doesn’t need to do any of that. He simply knows. This makes for an interesting contrast because, while Dazai is always looking for the angle, Ranpo just goes about his life, unbothered. He isn’t someone that Dazai needs to figure out, and that in itself is probably a little unsettling for Dazai—Ranpo is just Ranpo. There’s no hidden agenda, no underlying deception, just unshakable confidence in his own abilities. At the same time, I think Ranpo finds Dazai mildly interesting in a way he doesn’t find most people. Not because Dazai is a challenge—Ranpo knows he can see through him—but because Dazai operates so differently from him. He’s amused by Dazai’s schemes, the way he plays with people, but he doesn’t feel the need to engage. It’s almost like watching a child play with a puzzle you solved years ago.

3. A Quiet Understanding

Ranpo and Dazai don’t need to be close. They don’t need dramatic moments of bonding or grand declarations of friendship. Their relationship is more of a quiet, mutual acknowledgment—one genius recognising another, but with no need to test the limits. They don’t challenge each other. They don’t need to. And maybe that’s why their dynamic is so compelling. They just understand.

i see so many chuuya fics where he’s a player/a womanizer. and while those are all fun and beautifully written, i just have this gut feeling that chuuya is loyal as hell.

this is the guy that jumped off a helicopter and fought a literal dragon for a man he claims he doesn’t even like. imagine what he’d do for someone he loves, someone he has yet to lose and is terrified of losing.

all he wants to do is love you. he’s protective, but not possessive by any means. his time in the mafia has made him so aware of everything that could possibly harm you. even if its a 5 minute walk back to your place, he’ll drive you. if you’re out at a bar, he’ll hold your drink and/or keep an eye on all the other guys around you. he’s always practicing the sidewalk rule, always giving you his coat, and always reminding you that he would do anything and everything for you.

he knows that you’re a point of interest for enemy organizations. that because your his s/o, you’re a target for ransom or worse as a means to get back at him. and because of that, he’s constantly worrying. if even something feels off, he’ll call you, if not rushing to be by your side. you have to remind him that you aren’t made of glass.

oh, and god forbid you are actually taken captive. the world will see a side of him that he luckily keeps hidden.

[symphonyofsilence]

We don't know much about Dazai's life before Mori found him (just that the sheep had offered Dazai to join them and he declined)

But in "Dazai, Chuuya, age fifteen" there might be some clues:

He talks as if he previously hasn't been a part of the underground society. Like he's lived in the surface world.

His mannerism in general, even as a 15 years old is so refined. And the manner of his speech is different from the 15 y/o kids who are from the underground society like Chuuya and Shirase.

And the characters are heavily inspired by the real life authors that they're named after. Dazai already has so many things in common with the real Dazai Osamu. And the real Dazai Osamu was from a noble family.

So I think it's likely that Dazai was from an upper class family and ran away.

And... I think it's not completely unlikely that he might have changed his name.

in BSD, when a character is inspired by and named after an author who has a pen name, their real names are addressed. Like Mori Ougai being called Rintarou by Elise, or Fukuchi Ouchi being called Gen'ichiro by Fukuzawa or Dazai calling Oda Sasunosuke Odasaku, or 'Nakahara' being revealed to be the last name of the doctor who worked on the Arahabaki project and thus being Chuuya's "father" and so his last name being Chuuya's last name, while it's revealed that Chuuya might have an actual family out there, we don't know much about them but his father has the same occupation as the real Nakahara Chuuya's father; he's a retired army doctor who has established his own clinic. And the real Nakahara Chuuya was at first 'Kashimura Chuuya' before his father was adopted by his mother's family shortly after Chuuya's birth and his name was changed to Nakahara. Now maybe BSD's Nakahara Chuuya's real father's last name is Kashimura and thus before the age of 7 and merging with Arahabaki, Nakahara Chuuya might have been Kashimura Chuuya.

What I was getting at was that... maybe BSD's Dazai Osamu's real name is Tsushima Shūji (like his namesake, the real author) but he changed it after he ran away from his rich family and joined the underground. (But this theory might not work because Ranpo's namesake, the real author used a pen name too but Ranpo Edogawa seems to be the real name of BSD's Ranpo.)

I think people forget that Dazai controlling his heart is not just a one-off thing. Like he totally does it all the time.

The whole of the Prison Arc? That poison would've killed him way slower than Dostoyevsky by virtue of him making his heart incredibly slow, so it spreads slower. That's why he can afford to take his time with shit.

When he gets shot/stabbed multiple times? He can slow that shit down and lose less blood. He's so smart I love my little freak boy

Is this our Ace?

More info and why "Karma" is a refererence to a revenge.

Smarting over the recent attempt on his life, which had left two bullet holes through his hat and another two holes through his coat, Joe Masseria plotted bloody revenge in epic Italian Renaissance fashion.

Briefly it happened this way.

Masseria’s seemingly supernatural bullet dodging powers had given the hard noised, but superstitious, Valenti second thoughts. Second thoughts that had him suing for peace and walking into an ambush in one of New York’s most storied Italian restaurants, John’s of 12th Street, on August 11, 1922, a restaurant that has been used as a set on Boardwalk Empire and the Sopranos.

Now the Karma....

He was also killed inside a restaurant, by his own men.

Masseria was himself shot down by his own men while sitting in a Coney Island restaurant called Scarpato's Nuova Villa Tammaro. The assassins were Vito Genovese, Albert Anastasia, Joe Adonis, and Bugsy Siegel, led by Lucky Luciano.

According to The New York Times, "[A]fter that, the police have been unable to learn definitely [what happened]". Reputedly Masseria was "seated at a table playing cards with two or three unknown men" when he was fired upon from behind. He died from gunshot wounds to his head, back, and chest. Masseria's autopsy report shows that he died on an empty stomach. No witnesses came forward, though "two or three" men were observed leaving the restaurant and getting into a stolen car. No one was convicted in Masseria's murder as there were no witnesses and Luciano had an alibi.

And well... You know what they say...

Karma is a bitch

Hii! I'm new here, but I'll just get to the point. I want to know your opinion about something

I've heard a lot of people saying that Dazai would cheat on his partner. I know it's not true, but I just wanted to know your opinion about it

Have a nice day!

I do like people who just “get to the point”. ♥️ First of all, welcome to the family! Second, I don’t think so at all.

Dazai is not a bad person. The only scenario where I could see him being unfaithful is if he were afraid of emotional intimacy (which I think he would be) and tried to push his darling away. Though, even then, I am not sure he would actually go through with it.

Given his self-sabotaging and self-destructive tendencies, it is possible, but whether he would genuinely cheat or merely create the illusion of it is open to interpretation. His desire to distance himself from his darling would likely stem from his idealised view of them, believing he doesn’t deserve them because he sees himself as tainted.

However, in my opinion, Dazai genuinely wants to improve because he is exhausted by the constant emptiness he feels. Let’s say he has a darling who fills that void inside him—would he truly want to let them go? I believe he would only push them away under specific conditions, such as self-sacrifice, driven by the need to protect them from the inevitable consequences of being involved with him—both because of his dangerous life and his internal struggles.

That being said, considering how Dazai thrives on manipulation and control as well, even if he were to push someone away, it might not be purely self-sacrificial. It could also be a subtle test, a way to see how much they are willing to fight for him. (I somehow love how hypocritical he can be. The poor man is so stuck—please, someone shake him and tell him, “We can do this together.” 🥺 He is so lonely.)

Though, I think this is an extreme scenario, one where he is 100% invested in someone, particularly romantically.

I hope this answers your question. Have a nice day as well! ♥️

Dazai, talking about Chuuya: WHAT THE FUCK I WAS ARGUING WITH HIM AND I SAID “OOH YOU WANNA KISS ME SO BAD” AND GUESS WHAT? HE DID. HE KISSED ME. WHAT THE FUCK WHAT DO I DO.

[minimafioso]

Ramblings about ending themes and theories why Chuuya doesn't appear in them;

With the exception of S3's ending which shows the whole cast connected to the Dead Apple movie, Chuuya has not appeared in an ending song.

S1 & S2 are connected, focus on SSKK and Dazai.

S4 focuses on Atsushi and daily life at the Armed Detective Agency, though we get SSKK and Dazai at the end.

S5 focuses on everyone with a major role but has a lot of focus with Dazai and Akutagawa's relationship

Again, this one is particularly interesting as Chuuya has quite a significant role in Season 5 with his involvement in Fyodor and Dazai's plans. Almost the entire ADA is there, the Hunting Dogs, and several confirmed members of the Decay of Angels.

One could argue it's because his involvement was meant to be a surprise however, unlike in S4, Taniyama Kishou (Chuuya's Seiyuu) is listed in the cast of characters so his appearance was not surprising.

S3 was omitted as it included everyone who appeared in Dead Apple and is essentially a clip show to market it. The endings I included have art or edited scenes connecting characters significant to the season or tell a story.

It's interesting considering Chuuya drives the plot each season in some way.

Image heavy under the cut

Season 1 was his introduction season and while he didn't move that plot significantly as Dazai knew already where to locate the files, we got some insights into Mafia hierarchy and a brief glimpse of the duo known as Double Black.

Season 2 was him at his most impactful. Not only did we get the infamous Double Black episode but Chuuya also revealed himself and information on the Guild to members of the ADA who didn't know him and was a crucial person for Atsushi to see that lead to their truce with Port Mafia.

Season 3 is interesting because we had the 15 arc prequel episodes but they do not impact the main plot.

Instead we get Chuuya forced into the role of Port Mafia boss that ends with him being outsmarted and taken off the playing field due to him being a threat the ADA would not likely be able to handle. They took him out as quickly as possible and we don't see him again until next season

Season 4 gave us crumbs of Chuuya but his involvement saved the Armed Detective Agency and kept the plot moving forward

We also got the infamous OLD WORLD shot in the intro and I haven't forgiven Bones for that little bit of bait

Season 5 is infamous at this point, once again reminding us that Double Black is not a duo to be taken lightly. Chuuya's role was both as an antagonist but revealed as a secret ally. Once again he saved a member of the ADA and helped with dealing with the major threat, Fyodor.

Considering he is the second half of Soukoku, the duo that is the driving force in the partnership between Atsushi and Akutagawa, and a key piece that moves the plot forward, why doesn't he appear in the endings?

I have two theories, we'll go with that more likely one first.

My theory is that Chuuya will play a more significant role in the future. A running theme in the endings is a focus on Dazai and SSKK or members of the ADA. The only consistent member currently in Port Mafia that appears is Akutagawa.

Even by Season 5 Atsushi has not been at the ADA as long as it feels due to how long the series has been running. He's only begun to understand the landscape of Yokohama and the history ability users. Dazai introduced him to this new world so he's experiencing it in the light of the agency.

I wont go into my theory about Atsushi being the perfect pick to go to Port Mafia for narrative reasons, but that drives my next point. Port Mafia will probably have the spotlight again in the future. They've been fairly absent not counting the obvious 3 in s5 (Aku, Chu, Tachi)

Against all odds and near misses Chuuya and Atsushi have yet to meet. There's a lot of speculation about that but I think if Chuuya does interact with Atsushi it'll be because it's his turn to mentor the new generation of Double Black thus taking Dazai's place in the end credits. What does that mean for Dazai? Who knows, it's all just me theorizing!

The other theory?

Well, this one is more a sad symbolic one; the idea what Chuuya doesn't appear in endings because he doesn't get one. Well, to clarify; Asagiri doesn't pull punches with Chuuya and has stated Chuuya will not be having the easiest of paths. With the looming threat of the Storm still brought up by Verlaine in the present day it could mean he doesn't get a nice happy ending image like we see the ADA get in the S4 ending

"Chuuya’s character is an inexhaustible spring."

"I can’t describe the joy I get out of writing such a deep, intricate character and then having everyone read about him. I would like Chuuya’s fate to remain in the palace of imaginations. His destination is still a secret, although there is one thing I can say with confidence:"

"His will not be a peaceful, easy path."

- Asagiri Kafka, Storm Bringer Afterword

Edit: For clarity the symbolic theory is not the Asagiri plans to kill him off, but that he does not get a good ending showing off the people he cares for at PM the way we see the ADA in a group shot in season four

Asagiri says things won't be easy for him. But he's also very resilient so we'll have to see what is in store for him in the future
