#dazai dark era headcanon

[flowerwritter]

I'm writing a novel in which the protagonist is Two-Face's half-sister.

She's 16 and her romantic home will be Damian Wayne, and she ends up being bullied because of her brother.

But I'm not sure how to develop their relationship.

Something more protective or something more broken because I think he'd be a great brother.

Do you ever think about whether Oda ever received a call in the middle of the night from Dazai? How Oda knew dazai was just too stubborn to ask anyone for help. Maybe just once he was worried about the kid, he said ‘to call him if he ever needed him, he didn’t even have to tell him why, if dazai called him he’d go and get him, any time, anywhere’. How Dazai brushed it off with a joke, but one night Oda receives a call in the middle of the night and when he sees the caller ID his heart drops, and as promised, Oda gets in the car and speeds out to get Dazai without a single word needed to be spoken. Do you ever think about how many nights Oda might have lost sleep because he was worried about this kid? and how he’d never forgive himself if he needed him but he wasn’t awake to pick up his call? Do you ever think about how oda might have looked at this boy and thought “how can they not see he’s just a kid? How can they see him as a demon? As a monster? All I see is a scared, alone little kid. How can they not see this? How can they not think it’s inhumane to let him live in a literal metal container?” Ever think how he saw the empty eyes of this kid and wanted to take him in? Give him a warm meal? A hug? A real bed? Ever think how he must’ve felt knowing he was his only real friend, and how he must have felt when he was dying in this kids arms, this lonely, sad, messed up kids arms, leaving him behind? How he cared so deeply about this kid that his final words were to plea him to get out of that darkness, to seek light? Ever think about how proud he must be of this kid, now grown, for staying alive and taking in other lost children the way he wanted to take him in? Ever think of that?

15 dazai's camera roll but it's just like......

Like that.... at that specific angle.......... just big, black eyes far too big for his skull and an overall off-putting vibe.

Oh! And there's also Chuuya 'cause when is there not Chuuya (affextionate)

....and Akutagawa

Ango...

Oda's in there too...

Could u do dazai x reader with ocd?

Featuring: Osamu Dazai x gn! ocd reader

Content: sfw, fluff, slightly angst, mention of some swearing words, I believe that's it?,

Author's note: hiiii anon, so sorry for the late response, I swear I was working on it since I received it. I'm also working on all of yall's requests - I'm not sure if you wanted a fic, drabble, or headcanon so I just did a rock paper scissors.

Word count: 1k

❥ Dazai is a smartass, quick witted even, and don't forget that he works at the agency as a detective so of course he will quickly notice how you constantly worry about things going wrong—whether it’s leaving your water bottle uncapped or making a mistake at work. He sees you zoning out at the office, caught in a loop of anxious thoughts, and quickly deduces that it’s more than just everyday stress.

❥ At first, before really getting to know you, he was just a quiet observer. But he never judged, not even once. He’s got his own mental shit to deal with, so he knows how fucked up minds can be. He’d make mental notes of your quirks, just in case he needed to handle them during a mission or whatever.

❥ As he gets to know you better, he figures out how sweet and lovely you are—unlike the twisted side of your mind. It’s like an addiction for him; he craves that balance. He enjoys being friends with someone who has their own dark side, just like he does. Maybe you’ll understand where he's coming from, push him to be a better version of himself.

❥ It’s only after your relationship becomes official that he feels entitled to meddle in your problems. He believes that getting involved in such matters is only appropriate once there’s a solid, established connection between you. Until then, he's just an observer.

❥ You were the one who approached him first, explaining that you have OCD. You felt more anxious than you’d anticipated, having considered telling him many times before but never managing to do so because your mind held you back. He remained calm, and it was only when he revealed that he had known all along that you felt embarrassed. In his typically laid-back manner, Dazai might say, “Oh, I’ve known about your OCD for a while now. You don’t need to be embarrassed—it's actually quite endearing. It doesn’t change a thing between us. We’ll work through it together, and honestly, it’s no big deal.”

❥ One day, while on a mission with him and Atsushi, you were deeply focused on analyzing the crime scene. You managed to uncover evidence that even Dazai had missed, piecing together how the victim was killed with remarkable accuracy.

❥ Needless to say that dazai was surprised by how quickly you cracked the complex case. Even after the murderer was arrested, you continued to ramble about additional details, anxiously checking the file in your hand and worrying about missing something, though there was nothing left to find. Eventually he stopped you, gently holding both your wrists. As you looked up, apologising profusely, he simply shushed you, saying, "It's fine. The case is solved, and we’ve caught the murderer."

❥ Atsushi the poor kid he is watched the exchange between you and Dazai with curiosity. When you reluctantly handed him the file with a nod, Atsushi leaned in and whispered to Dazai, asking if you were alright. Dazai simply smiled and replied, "They're just the perfect detective, doing their job flawlessly."

❥ Dazai is surprisingly attentive to your needs when it comes to your OCD. If you’re stuck in a loop of checking something multiple times, he’ll gently steer you away from it by engaging you in conversation or distracting you with a task. He might even playfully mock himself to make you laugh, using humor to ease your anxiety. “Looks like I’ve accidentally left my keys at home for the fifth time this week. Isn’t that a catastrophe?”

❥ If you’re particularly anxious about a big case or an important event, Dazai might surprise you with a comforting gesture. He could leave little notes or small tokens of reassurance in places you’d find them, like a hidden message in your desk drawer or a comforting snack in your bag.

❥ When you’re feeling overwhelmed, Dazai has a knack for knowing when you need space and when you need company. He might give you space to deal with your thoughts but always makes sure you’re not alone. He could show up with your favorite coffee or a calming playlist, knowing just when to intervene.

❥ Dazai might not always express it directly, but he has a deep understanding of how your OCD affects you and often subtly adapts his behavior to support you. He might avoid making sudden movements or loud noises if he knows it could trigger your anxiety. His sensitivity to your needs shows how much he cares.

❥ Dazai would likely offer reassurances in his own, less conventional way. Dazai might not be that sentimental boyfriend but he makes casual but heartfelt statements that affirm his love, such as “You’re the only one who can put up with my nonsense,” or “I can truly be myself with you, without a second thought.”

❥ Dazai would be more mindful of his humor, staying away from jokes or comments that might trigger your OCD. He might use humor in a way that’s supportive and aligns with your sense of comfort rather than distress.

❥ If someone makes fun of you, Dazai would likely handle it with a blend of nonchalance and protective instinct. He might casually brush off the mockery with a witty comment, like, “Oh, they’re just jealous of your intellect,” showing his confidence in you. If needed, he would also step in to defend you.

HEADCANON

Dazai has numerous moles scattered across his body. Oda, who has just a few less but a very noticeable one right under his left jaw, once told him that it was where his past-life lover used to kiss him more often. After Oda’s death, Dazai wished that someone had kissed Oda’s jaw mole often enough so that Dazai could find him in another life as well.

A bit of Odango: Dazai never knew that Ango was the one who told Oda that story. Ever since then, Oda made sure to always kiss Ango’s mole every time he said hi or goodbye to him because of that same story.

A bit of Soukoku: Dazai told the same story to Chuuya, who made fun of him, saying that he was definitely very different in another life to have that many moles. But ever since Dazai shared the story, Chuuya's lips started to linger around Dazai’s moles, especially when he had a bit too much wine or after Dazai cupped his cheek to deactivate corruption. It’s not Chuuya’s fault if the guy has moles even on the palm of that same hand. Dazai never points it out; he secretly wishes the story is true so that Chuuya will find him in another life.

this did modest numbers on tiktok, i hope y’all like it too! here’s my…

✨dazai headcanons✨

but they’re all rlly specific & weird

(coming from a cosplayer who’s been in the fandom since 2016)

he has an astigmatism that went untreated for so long he’s now partially blind in his right eye. he needs glasses but hates his old pm pair and never wears them in public. he’s too lazy to get his prescription renewed/hates going to the doctor so they’re not even up to date for his vision

that’s why he’s a bad driver— he can’t fucking see

he drives/reads better if he closes one eye

mori forced him to get braces after he formally joined the port mafia. he had a lisp for the first few months and would blackmail ppl if he did it in front of them

he hid his bad vision for a long time, but mori eventually noticed and forced him to get glasses too. he fucking hated wearing them and “accidentally” kept breaking each new pair mori got

after that, mori got him contacts but he would lie and throw them out just to be defiant (totally not bc they squicked him out)

he originally started wearing his bandages because no one would touch him bc of his ability

he has awful tan lines bc of his bandages, his face and hands are tanner than the rest of his body, but since the sun can permeate light clothing/bandages he also has random splotchiness all over his body, especially his shoulders, arms, & back

in 15, dazai got so excited he was 5 cm taller than chuuya bc he was always the one being bullied for being short/malnourished before they met

at 16, chuuya grew slightly faster than dazai and started teasing him. dazai freaked out and started wearing lifts for a brief period of time. he was researching poisoning techniques to reduce growth right before he finally got his own growth spurt <3

he has chronic insomnia and is a scarily light sleeper. usually gets anywhere from 3-6 hours of sleep a night

he constantly has dark circles under his eyes as a result

whenever he shares a bed with chuuya, he’ll sleep twice as long as normal. at first, chuuya would get mad bc he was a huge brat to try and wake up, but now he lets dazai sleep in as long as he wants

his sense of taste is abysmal, which is why he likes really salty/spicy food. they’re the only flavors he can actually taste

he doesn’t decorate or furnish his ADA apartment because he’s scared that once he gets attached to the place, it’ll get taken away

he constantly beats himself up for not thinking to take odasaku’s coat with him. he bought his current one because it looked similar

he refuses to touch any of his pm salary, so it’s just kept accruing interest and is actually obscene at this point. he asked ango to “handle it” and cover banking stuff under the condition he gets to take out any expenses he wants. it irritates ango to no end that dazai won’t do anything with it

the day kunikida finds out about dazai’s pm bank account will be dazai’s final day on this earth

when he was 15 he was unironically into screamo bc “it screams for me when i can’t.” thought linkin park was super hardcore & his favorite song was “numb” (fucking loser)

he NEVER brushes his hair. like he doesn’t even own a fucking hairbrush or comb until chuuya has a conniption over it and starts keeping one at his apartment

whenever chuuya tries to brush his hair, it’s like trying to wrangle a feral cat. they’ve gotten in physical fights over it that always end with dazai pouting for the next hour while chuuya laughs at how flat his head looks without the rat’s nest

uses dollar store 9-in-1 shampoo/conditioner/bodywash/motor oil. it’s ocean breeze scented! :)

he’s had the same fake driver’s license since he was 15 and never bothered to get a real one

he actually has decent medical training from spending so much time as mori’s apprentice. about the same level as a battle medic would have. capable of stitching wounds & performing surgery, but not as good as yosano even without her ability

yosano has tried to reach out and bond with him about their shared pasts a few times, but he always comes up with an excuse to leave. she eventually gave up on asking

one time, he got badly wounded and had to be treated by yosano. she had to sedate him because her ability doesn’t work on him, and he called her mori the whole time. he doesn’t remember, but she never forgot and stopped trying to spend time with him

[itzmoonies]

I have a very sad hc but HEAR ME OUT

Okay so I saw a post that spoke about how Dazai didn't show any emotions when Mori killed the former boss right in front of him. Dazai was a child. Seeing a murder for the first time and… Nothing. No expression. Just acceptance. As if his body is here but not his mind. He's dissociating.

Look at that look. He's not focused. He's just looking at whatever is happening.

So what if it happens each time he commits a crime? What if each time he kills someone, he's not fully realising his actions and only realizes it later, but it doesn't hit him so hard because it happened slowly.

Well, I headcanon that one time, Dazai killed a bunch of innocent civilians for X or Y reasons. Mori told him to. So he did it. But he usually didn't kill innocent people. Usually it's the mafia's ennemis. So the realisation hit him right as everyone's already dead. He's there, surrounded by corpses. He's the reason they're dead. His hands is covered in blood. The realisation hit him so hard he thought he was gonna vomit (he didn't).

Very joyful 🫶🏻‼️‼️

fem 15 skk!! 💕💕

[blindblossom]

Port Mafia Soukoku but Dazai’s heart hiccups and short-circuits the moment he sees Chuuya doing a full split while working on his laptop (“Why are you looking at me like a mackerel, ha?! I’m exercising and working. It’s called multitasking!”) and realizing that—

Oh.

Chuuya’s kind of hot. And he is gay panicking.

Dazai: You are… flexible.

Chuuya, thinking he’s misheard: Well, yeah? I’m behind with the paperwork and I should be at the gym now.

Dazai: Oh.

Chuuya: Why? Ya have a problem?

Dazai: 🧍

Chuuya:

Dazai, Oh my god he’s really hot what do I do now: …Ew.

Chuuya: WHAT DO YOU MEAN BY EW?!

[frostlineprince]

[calmlb]

one of my favorite headcanons is that Dazai defected right around Chuuya’s birthday

we don’t know exactly when he left, but we do know it was after october 26 & before june 19, & according to clues in dark era it sounded like it was around springtime in yokohama

idk enough about yokohama weather to know exactly what month it was but imagine…

Chuuya had been sent on a mission in the west for 6 weeks. he returned late in the afternoon on April 28th– just in time to ring in his 19th birthday with his shitty partner.

because why not? he’s got nothing better to do.

he’s even got a bottle of 1989 Petrus waiting to be popped open.

he reports to Mori for debriefing & all he can think about is how beating the mackerel in that racing game they’ve been playing while he was away would be the perfect way to start off his 19th year.

but when he turns to leave, the Boss stops him, telling him there’s something that he should know…

Dazai disappeared 2 weeks ago, & has now been declared a traitor to the mafia.

Chuuya’s blood runs cold. he doesn’t know how he made it back to his apartment— head muddled by hurt. shock. confusion. exhaustion.

he tosses his coat on the back of the couch & the first thing he sees is the bottle of vintage Petrus— still waiting for the celebration.

and celebrate he did.

Chuuya celebrated his liberation from that waste of bandages he called a partner.

he celebrated the success of the solo mission he’d just returned from.

he celebrated the end of the reign of the infamous double black.

he celebrated the fact that he’d survived 4 years of partnership with that shitty Dazai.

he celebrated Dazai’s freedom, which would likely save his life… the freedom Chuuya hadn’t been able to attain. he’d been left behind in the darkness by the one person who got it.

the one who believed in & fought for Chuuya’s humanity when no one else did.

Chuuya celebrated his 19th birthday. alone. again.

(he hadn’t even said goodbye— hadn’t asked Chuuya to come with hi-)

no.

Chuuya shook away those thoughts. he needed to clear his head. he wiped the back of his hand across his eyes & stumbled drunkenly across the room to grab his keys.

he made his way to the garage where his car was parked, clicking the button to unlock it as he approac-

BOOM!

Chuuya was thrown backwards onto his ass, barely able to catch himself in his drunken stupor. he blinked through bleary vision at the flames that were engulfing his car.

and wasn’t that just par for the course? the icing on his nonexistent birthday cake.

so much for that drive.

Chuuya watched the flames burn, & maybe it was the alcohol talking, but it felt almost symbolic— like closing this chapter of his life. all he could do now was move forward. just like he always did.

but not tonight.

tonight he would stumble back to his apartment & collapse into bed.

(in his inebriation, he hadn’t even noticed the black fabric burning up right along with his car)

he woke up the next morning, freshly 19 with a killer hangover, a smoldering car, & a missing ex-partner.

when he found the nearly empty wine bottle, he was kind of glad he hadn’t taken that drive…though his memory from last night was a bit fuzzy— what the hell had happened to his car?

his phone chimed with a text from Kouyou.

happy birthday, lad. don’t do anything stupid.

Chuuya couldn’t help the twitch of his lips. there were still people here who cared about him.

not long after this, he would be promoted to executive & decide that the Port Mafia was his family.

but for today, he would nurse his hangover & curse a certain mackerel’s name as he beat every high score between them in that stupid racing game.

happy freaking birthday to him.

the car bombing was inspired by this post bc it’s canon to me <3

[akirayuri]

Post fire down ( 15 ) Soukoku holding a cashier at gun point as they rob a pharmacy off it's painkillers, antiseptics, bandages and surgical alcohol and a whole fucking row of gummy bears, cause they lost their wallets. The poor guy is torn between being scared to death and genuinely concerned as the two kids hold a fucking gun to his head ( one looking like he's straight out of a vintage horror flim with bandages and dark clothes and all, with a face like a fucking dead doll or some shit. And the other cosplaying a street racer, well. Yeah. With the most dirtiest, Spitfire mouth to exist.) While they rob candies and medical supplies, leaving blood trails in their footsteps and tiny hand prints.

[tulipe-rose]

Dark era skk hc: Chūya and Dazai had matching belts that were too long for anyone's waist that were one of the few items they found in a raided house (they doubled as a weapon they could use against each other when needed). Chūya refused to wear it, but he always had it with him. Dazai would carry it around and would use it for bizarre jobs, but he never wore it, even after defecting. He never got around to throwing it out.

When the agency were making Atsushi an outfit, Dazai decided to give it to Atsushi; it felt nostalgic seeing him question it's height. It suited him well, and it would be better to finally see this belt actually be worn instead of used for anything but what it was made for. I wonder if Chūya would notice if he and Atsushi were to meet.

(Chūya began wearing the belt everyday since he lost his other one during a fight, and no one dared to comment on it.)

[cornflowersandspoons]

Me: Okay this will be nothing but a quick sketch....

Me, two days later: *is drawing individual freckles on Dazai's face*

[sickficideas]

hellooo

okay i think most of us like odasaku taking care of a sick/injured dazai (i don’t know if you've read the day i picked up dazai but he literally can’t go two seconds without going 'oh that’s a child') BUT i love the idea of ango stepping in too 😭 im imagining he gets stressed when dazai shows up clearly unwell and maybe even teams up with oda too -who has seen it all atp and is not that worried since he knows how dazai is- but ango clearly gets worried and dazai makes fun of him for it but appreciates it somehow ??? sorry for the rambling 😭😭

I'm waiting for an official translation on The Day I Picked Up Dazai but I absolutely love the little bits I've seen of it and I love this as a concept 😭😭 I also really love Ango not 100% computing Dazai's age because he only meets him in work settings most of the time so when he's sick and being taken care of he's like okay this is truly a teenager wow. Ango getting overly stressed about Dazai's condition even if it's just a cold or something and Oda has to assure him he's fine and it's nothing to worry about and Dazai giggles and calls him mom as a joke...my family my tragic broken apart family
