yet another dazai hc post! U^ェ^U

--

i'm not sure if this is a popular headcanon?? but ive seen it in quite a few fan fictions and oomfs i've proposed this idea to agreed heavily so i thought i would share it publicly and see what everyone else thinks!! (this hc is 100% just me projecting but thats alright <3)

i would like to imagine that dazai has chronic nightmares, so much so— that nearly everyday of the week he's waking up in a cold sweat from them, wether it be related to his past— or some random nonsensical one. in both the manga and anime we see him sleeping during work hours and rather than it being due to overall laziness i think about him not being able to sleep during the night. dazai's always getting caught sleeping during work hours, and in the beginning everyone in the ada just assumed it was him avoiding work, either that or he's trying to annoy kunikida... when in reality it's because it's the only time he can get actual rest, rest uninterrupted by his nightmares.

no one other than kunikida really cares, so it's not like he's interrupted much anyway.. though it gets quite lonely when you're practically nocturnal, it's a given that dazai would get quite depressed at the fact he hasn't had much human interaction other than when he shows up to work, is awoken by kunikida who's yelling, and when he's leaving to go home.

--------

a little kunizai add on! >_<

in addition to the headcanon, i like to think about what would happen if kunikida found out about it, how worried he would be, and how he would insist dazai get actual, proper sleep. but of course he's unable to— as stated before. the two eventually come up with a compromise when they realize dazai is able to sleep properly when others are around him, or when he's in bed with someone. so kunikida begins coming over after work and sleeping in dazai's bed with him instead. it's definitely embarrassing for the taller man, but he cares for his coworker, so he endures it.

(this is definitely a little out of character.. but hey!! it's for fun♡)

“Chuuya wasn’t in Dark Era, why is he in this art??”

wdym, he’s right here 🤨

[loulitzin]

Headcanon: Chuuya being on the ceiling is never planned—it just happens.

One second, he’s standing like a normal person. The next? He’s casually upside down on the ceiling like it’s the most natural thing in the world.

Half the time, he doesn’t even realise he’s doing it. Someone pisses him off? Gravity shifts before he even thinks about it. Need to get out of a conversation? Ceiling. Dazai being insufferable? Ceiling. Need a moment to process? Ceiling.

At this point, the Port Mafia barely reacts. New recruits get spooked when they realise Chuuya is watching them from above like some kind of feral gargoyle, but the executives don’t even bat an eye.

Meanwhile, Dazai has an entire catalogue of dumb jokes. “Flew too close to the sun again, Slug?” “How’s the weather up there?” “Should I start leaving food on the ceiling for you?”

One day, Chuuya’s going to lose patience and dropkick him from above.

Might make this a running series of HCs.. someone please draw feral gargoyle Chuuya on the ceiling I will love you forever...

[unicornpopcorn14]

So we all know by now that Dazai is comfortable enough around Chuuya to show nervousness/worry.

Enough times for Chuuya to pick up on that pattern. The pattern, may I remind you, that doesn't have evident correlation to either nervousness or worry to most people. One that can even be interpreted as misplaced given the situation.

Which means that Dazai has done this in front of Chuuya so often, that Chuuya at first was hella confused, before he finally made a connection between when and why it happens. And still remembered that connection after four years of separation. Which gets us to my point:

What if this isn't the only emotion Dazai displays weirdly?

What if he has multiple unconventional patterns he displays for sadness, frustration, content, or disgust? The times he really feels them, and they become too strong for him to just deal with normally? What if these are the only times he's actually being genuine with his emotions?

And Chuuya is the only one who is familiar with them all?

Dazai would be jumping rope and Chuuya would be like, "quit sulking, let's get icecream"

Dazai hanging upside down on the couch and Chuuya going, "It's okay, mackerel. You can cry."

Dazai actually crying, full on heart-wrenching sobs, and Chuuya unironically going, "What, good news?"

It's just... comforting, for one person in Dazai's life to read him like a book. Everyone else would look at him like he's crazy, displaying wrong emotions/behaviors at the wrong time, but Chuuya knows that it's just how he processes feeling properly, and thus he's the only one Dazai can count on to put things into context and understand, which makes him display them even more openly.

Because Chuuya never shamed him for his quirks, as much as Dazai never did his.

Something

Something unknown to me possessed me for two hours and made me draw this

What should they name dazais new twin? Wrong answers only

[kiksniko]

i am once again sick. have more sketches

Dazai can never beat the high maintenance allegations. He needs you with him at all times. I mean what would he do without his belladonna, he's convinced that if you leave his side he'll die.

That also translates to the bedroom, his long slim fingers have to be on you during ever moment of your love making. He needs to know that you're real. But his way of always having his hands on you always ends up in you being oh so overstimulated. I mean you need to feel as good as you make him.

He loves when you orgasm. His mission every time you two have sex is to break the record of how many times he can make you cum. Not to even mention he has such a high sex drive. He needs sex like all the time. And oh boy his stamina you could be going for hours if you have the right amount of time.

Most of it is just him between your legs coaxing one orgasm after another. Once he's satisfied in how many times you've come all over his face then and only then will he sink his cock into you.

But if you think that once he comes inside you that you'd be done, you are dead wrong. I mean you made him so pent up with the sweet whines that came out of your mouth. So why wouldn't he need to cum 2-3 times inside you?

[orionthenightfury]

Can we all agree that teen Dazai bites? I don't know why, but teen Dazai just looks like he would bite people. Specifically Chuuya.

[shall-we-die]

Imagine Dazai being asked to hold a strangers baby for the first time after he joins the ada. This small vulnerable incredibly fragile and innocent thing sleeping unaware in his blood soaked hands. I think he would freak out a little bit.

╔‌‌‌‌═══════════════•⊰•°༄༚

{Something precious}

☰[Main list]•⊰ Bungo stray dogs

╚═══════════════•⊰•°༄༚‌‌‌

Let's say an abounded baby is found in a alley and everyone gets involved in finding his parents. Yusano is also busy, so she gives the baby to Dazai to take care of it.

Holding the baby in his arms, Dazai looked down at the little baby, his whole heart was filled with an strange feeling, a wave of sadness washed over him... He held the baby with a nervous grip, he was afraid to drop the baby or hurt it in some way. Dazai couldn’t help but look at the tiny vulnerable infant in his arms, that this baby is so innocent and good and then there’s him, an ex mafia executive covered in blood and crimes. Dazai looked at the baby in his hands, it’s small face, it’s tiny hands and feet, the little sounds it made while sleeping made Dazai’s heart ache in a painful and nostalgic way. That baby was so innocent and gentle…and he was anything but that. The smell of the baby's body was an accurate description of the smell of purity and maybe heaven?... something that dazai was far from. Dazai tried to hide his expression, but he couldn’t, the sadness was still in his eyes. He looked at the baby and could only think about his life. Once the baby was taken away, Dazai looked down on his hands, he saw all the bloods from his past on them for a second. He closed his eyes and after taking a deep breath, he turned to continue his new job at ada.

[azapofinspiration]

Okay, so Chuuya needs reading glasses but he decided to switch to contacts sometime after SB and usually only uses his glasses at home. Which is fine and works out great.

Except Chuuya needed to wear the vampire contacts at Meursault. And he didn’t bring glasses with him out of habit. He can’t read anything.

The red contacts already made it hard to see in general but he can’t read anything while wearing them (the only consolation he had was that he also couldn’t see Fyodor’s smug face when he thought he controlled him). Then afterward he’s shoving his face close to his phone and squinting to try to see if he’s gotten any news about Yokohama while trying to also text anyone he can to speed up their extraction.

Dazai, trying to hack computers to contact Ango: You know you can make the print bigger so it’s easier to read, right?

Chuuya, also a total grandpa when it comes to phones: I can what?

[bloodsherry]

Dazai flirts with everyone for fun, but when it gets serious and they flirt back, he explodes and his brain stops working. He blushes and babbles like a fish out of water.

When Chuuya realizes, add 1+1, oh boy, the real fun begins.

Chuuya headcanons

* Secretly a cat person: I know that everyone already know that he is a dog person but Despite his tough exterior, Chuuya has a soft spot for cats. He'd often sneak out to the local cat café to pet them.

* A skilled cook: He enjoys cooking and is surprisingly good at it. He often makes elaborate meals for himself and sometimes shares them with Dazai.

* Has a fear of heights: Ironically, for someone who can manipulate gravity, Chuuya has a fear of heights. He avoids looking down from tall buildings and prefers to stay on the ground floor.

* Loves to collect hats: His signature hat is not the only one he owns. He has a collection of different hats that he wears depending on his mood.

* A lover of spicy food: He has a high tolerance for spicy food and enjoys trying new dishes from different cultures.

* A terrible dancer: Despite his agility and grace in battle, Chuuya has two left feet when it comes to dancing. He avoids social events that involve dancing at all costs.

* A secret romantic: Despite his tough exterior, Chuuya believes in love and romance. He often writes poetry and songs about love, but he never shares them with anyone.

* A collector of vintage items: He has a collection of vintage items, including old coins, stamps, and antique jewelry.

* A terrible liar: He is terrible at lying and often gets caught in his own lies. This often leads to comical situations, especially when he tries to lie to Dazai.

* A secret fan of anime and manga: He enjoys watching anime and reading manga in his free time. He often hides his manga collection from his colleagues, fearing they will judge him.

1. The Tactical Ceiling Advantage

Chuuya doesn’t just stand on the ceiling—he weaponises it. Mid-fight, he’ll dodge an attack by casually flipping upwards, forcing his opponent to scramble just to track him. It’s almost unfair. No one ever looks up when fighting indoors, and he uses that to his full advantage. Dazai, of course, makes it a point to always look up. It’s saved his life more than once.

2. The Mafia Has Given Up

At this point, Mori doesn’t even question it. Kouyou doesn’t even look when she scolds him to get down. The Black Lizard has stopped reacting entirely. Higuchi still flinches. Tachihara once made the mistake of standing under him—Chuuya dropped down and nearly gave him a heart attack.

3. It’s Not Just for Battle

Chuuya claims he only does it for practicality, but the truth? It’s a habit. When he’s thinking, he sometimes finds himself pacing along the ceiling like it’s the floor. When he’s drinking, he’ll kick back upside down like it’s the most normal thing in the world. One time, he fell asleep up there and woke up to find Dazai had stacked chairs trying to reach him.

[formiito]

Hello! May I request some pre-relationship/crush headcanons with Kunikida, Atsushi and (ADA) Dazai (all separate) with a reader from the port mafia? How would they realise they are in love? How would they handle it etc etc. I love love love crush headcanons with all my heart<33

heart to heart — crush hcs!!

author's note: i'm an idiot who wrote this fic almost exclusively in hours 2-4 am. my eyes are in pure suffering. an unhealthy amount of fiona apple and unreleased lana del rey songs went into writing this. idk how to write headcannons so this ended up kind of like a fic with bullet points lmao 

— KUNIKIDA

• Working with the Port Mafia is something he is (unfortunately) no longer a stranger to. Still, an extended mission was a bit too risky for his tastes. But everyone said that he was fine, so he should be, right? If only he knew what novel sort of trouble he would face once he took the job.

• For the mission, he was partnered with you. You must've been of a different unit, because he is sure he has never seen you in person before. Except for being mentioned in passing by Dazai in his inane conversations, there was little he knew of you.

• At first, he was skeptical. Not sure whether he could truly trust a person with your affiliations to not double cross him in some way. However, you proved yourself capable soon enough. You worked with decisive efficiency, and even with his rather ridiculously timed schedules, you seemed to have no trouble keeping up with him.

• Needless to say, you two got to know each other fairly well over the course of a month. By now, you were acquainted atleast a little of his likes and dislikes. The late night sessions to plan out the routes and inspect the case files over and over; your friendship sprawls over late cups of coffee, the impatient scratching of pen on paper, and the files scattered on the table while you both worked.

• This was still professional; he'd reason with himself. So what if he's had a few drinks with you once in a while? So what if you've been spending a little too much time at his home lately?

• Dazai’s endless teasing on the matter did not help. At all. As he grows more and more defensive, he wonders if he has grown a little too attached to his new partner.

• Kunikida isn't an idiot. Even he can see how much you've made an impression on his life. He simply isn't ready to admit that this could possibly be romantic in nature. After all, you fit none of the ideals he's decided for his supposed future partner. In some form of pointed irony, the pages of the notebook that carry said ideals are also filled with the random, little things he's noticed you need; chapstick, switchblades, pens— all for them to be ready when you inevitably reach for them.

• Nor can he help stealing a littlewhen said chapstick swipes so elegantly along your lips.

• Absolute gentleman, with or without a crush. Opens the car door for you on the other side, makes sure you have your seatbelt on, makes sure to watch your back while you both do field work. It’s just a nice thing to do, he reasons, but feels your touch like it was branded into his skin where your hand accidentally brushed on his elbow.

• The weeks that follow after are drawn out, confusing. As time goes on, he cannot help but read into your every action, taking note of all the little details that outline you as a person; from your tastes to little quirks. While you seem blissfully unconcerned, he could not help but feel the weight of the tension between your conversations. It is not these emotions that scare him, but their intensity. His hands tremble as they once again bandage your wounds from the day’s work, mouth dry as he looks at the gashes you think nothing of—and he wonders since when he started caring so much.

• Kunikida may be a man of his ideals, but he can be honest with himself when he needs to be. And whether he says it aloud or not, he’s already known the effect you have on him. He's known it for a long time.

• When he inevitably confesses to you, there is nothing special about it. It's another evening at his house discussing work, and when you both take a break from investigation, he brings it up to you. He isn't expecting the sentiment to be reciprocated. In fact, he is not sure he even wants that to happen. He says it to be honest. With himself and with you. You deserve to know. And perhaps if he said it out loud, the feelings would subside, even for a little while; with a definite answer, he’d have a reason to put out the growing ember.

• Nothing could've prepared him for the shock of learning that this troublesome feeling could possibly be mutual. And nothing could have prepared him for the coy kiss on his reddened cheek after.

— ATSUSHI

• someone help this poor guy

• no, he's really hopeless with it, but let me explain

• When he was asked to collaborate with the Port Mafia once more, he expected to be paired with Akutagawa once more. You were a pleasant change of pace. At first, he was only met with your suspicion; something that drove an initial rift between the two of you. You weren't sure whether you could truly trust this weretiger you've heard so much about to hold up his end of the deal, and neither could he rely on this complete stranger who regards him so frigidly. However, you both were indebted to your respective organisations—it had to be worked out.

• Your staunch independence, and the confident countenance that carried with it an understated superiority, no doubt the effect of years of experience; at first it irked him. It made him taste a little of the helplessness that trailed him like a shadow all those years ago. He attempted to chase away the feeling; biting back at your subtle digs at his skill and experience, trying to keep up with you as best as he could. You matched each other surprisingly well when you both were at your most competitive; the combination of your finesse and his strength was lethal in the most satisfying of ways.

• Over the weeks, you both get to know each other a little better. The small talks on the way to station were something that he was, despite knowing better, looking forward to. He always seemed more affected by your banter than you were by any retort he could possibly throw at you; and when the sly curve of your lip made him feel the strangest sensation of a sort of rush in his veins, he made no notice of it.

• After that morning, this strange feeling had been growing worse. Steadily through the days, but even so he could point out that the emotion that seemed to sit just beneath his chest was unfamiliar. Sometimes he had to force himself to look away from you just to get it to stop and actually be able to hear what you were saying over the erratic beat of his heart. It was blatantly obvious to everyone but him, and despite the constant teasing and prodding by Dazai on what’s got him so nervous, he still assumed it was merely admiration. Perhaps he was simply in awe of your abilities. For weren't you so impressive when you dispatch your targets so effortlessly, or when you execute such flawless plans with an ease in your mien that makes it look of so simple?

• But then that begs the question as to why he still stares in a daze when you're doing nothing, just catching your breath in the wall crack you had pulled him into to throw off the people chasing you both; his back hitting the wall and you the only separation between him and whoever was at your tails, stalking the alleyway outside. Breaths held, not making a sound; if you both got caught, this was over, and you both understood the stakes better than anyone. He definitely knew just what was waiting for the both of you out there, and that just made the situation far more frustrating, because then why is he so absorbed in how pretty your jelly-like gaze is, or how cool you looked back there when you silently felled that patrol guard? He feels like his brain has melted. Or atleast the still working part of it, because it's not even the first time you've had that effect on him.

• Your hand tentatively shifts, and for a moment he snaps out of the daze. There is abject fear in his eyes, because what the fuck are you doing when the both of you are one slip up away from messing up this mission you both worked so hard on? Yet your fingers, trembling with the rush of adrenaline and the fear of death, wipe the blood on his cheek, observing a rather deep cut inflicted by the serrated edge of a dagger. He could take a hit, but for some reason worry seemed to claw at your mind relentlessly until you could make sure he was okay.

• Perhaps he'd stopped functioning right there and then, because when the footsteps receded and the coast was finally clear, he could barely hear you say that it was safe to come out. Instead, his first move is to hold his heart and take a deep fucking breath. Not just to calm him down from being chased like that—for he's already been chased so many times—but to stop thinking about that brief, soft touch that reasonably, should not even affect him.

• At this point, he's kind of convinced he's going crazy. And like so many problems in his life, there's only one other person to hear it. Coincidentally also the worst person to go to for that kind of counsel.

• Dazai.

• Bastard laughed for fifteen whole minutes before explaining in broken wheezes what Atsushi was possibly afflicted with. Then immediately began sighing and bemoaning about having to help his coworker with silly love problems once he finally stopped cackling like a witch.

• After this… enlightening conversation, Atsushi promptly decides that he's never going to be able to look the man in the eye ever again.

• Now, he's got a whole slew of new problems going on. This mission, you, the fact that he just embarrassed himself in front of his coworker, and that he had no idea how to even face you after this realization.

• Naturally, he wants to avoid this situation. Atsushi doesn't even consider telling you. He wants to, so badly. His throat feels tight when you look at him so sharply, and he can't help but feel that if he sticks around you for too long, you'll look straight through him and somehow find out. But he has every reason to think this won't work out. Every reason why it won't work out. It wasn't the time for love, not even in the small moments of respite between the constant violence you two had to deal with.

• This distance he's been keeping from you…there is no doubt that you feel it too. He can see as much. The disappointment in your gaze when he keeps on pushing you away; it hurts. And he knows with the way your hands are curled in fists now that you're at your breaking point.

• But instead of the argument he thought this would inevitably lead to, you simply pull him into a corner. In the most sincere tone he's ever heard you speak in, you ask him if you did something wrong. Between your deliberate words, your hands on the collar of his shirt that hold him in place with nothing but gentle firmness, and the emotions that he tried so hard to stifle for the past few weeks; he confesses. Leaves nothing unspoken, even if he consciously knows that this is a bad idea. Knows he shouldn't hand you that kind of power over his heart.

• Yet he doesn't regret it a single bit when he feels your hands leave his shirt collar and wrap around his shoulders, your silent answer that kills the bitter uncertainty left in his heart and replaces it with relief.

— DAZAI

• Your history with the brunet was brief, but not something he has ever forgotten. He’s not quick to forget faces in any case, but yours remained in his memory still.

• You both worked together fairly often some three or four years back, the timeline is blurry in his mind now—in those days, your presence seemed like it would be a permanent fixture in his life. Something to count upon. Perhaps he had hoped for the fact, until an year after when he finally decided to leave this life in the dust, and you with it.

• At the time, Dazai had dismissed those feelings as puppy love; the sort of infatuation that comes with simply being of that age where every emotion feels so amplified in intensity. You were one of his first friends, it was only natural to want to cling on, wasn't it? Only with time it became easier to ignore the hold your presence had on him, his mind too consumed with the ongoing chaos in his life to think about that craving he had during initial weeks of your separation— thumb trembling over the call button.

• A few years after, seeing your face stirs nothing in Dazai. A feeble sense of regret is all that remains, and within a few seconds even that dies off. You've changed, definitely; rough-hewn edges from mafia life, knife-hand no longer trembling when it goes for the kill. Decisive, swift movements, a certain confidence in your words that comes from experience. How the glimmer that used to be in your eyes has long since been clouded over. In a way, it makes him feel closer to you, that your soul is being slowly chipped away, just like his.

• Initially, you regarded him like any other professional acquaintance. Not daring to breathe a word of the past, even when you wanted to demand an explanation out of him so desperately. Anything to make the memories of your shared past more bearable. You know better than to give into those whims. If only for the sake of your mission, the past had to be put aside. Between the both of you, there seemed to be a mutual, unspoken understanding for the need to let go. Your slates are cleaned, and you both once again end up in the same place you started; Yokohama’s shipping docks.

• Over the weeks, being around you feels easier. You both work well into the nights, but it's a little more bearable around your company. The banter is easy between the both of you. Lips curved into a cheshire grin at his antics, you always seemed to be more amused with his actions than annoyed.

• Even now when he decides that diving head first into the sea would've made for a perfectly delightful method of suicide, a knowing sigh leaves your lips, painstakingly pulling him out of the fishnets with a firm grip on his beige coatsleeve. Of course, the effort is in vain when you lose your footing and end up falling into the water with him too. Splash!

• Somehow, even when he's walking home, sopping wet in the winter breeze, he feels strangely warm as you chide him, observing how your lips twitch as if to hide a smile.

• It’s your fault, really. Perhaps if you both didn't fit together so well, if it wasn't so effortless to be around you, he might have avoided feeling the same way around you again. It's not lost upon Dazai, how comfortable he's getting with your presence, especially when he knows it's a temporary one. A fact that he is compelled to face again and again everytime you both end up in the field.

• The danger they were facing were still very much real. Despite how confident you seem to be in your ability, your tight shoulders and shaky breaths betray you in the heat of the moment. Through your hesitation to follow through his plans, you still trust him at his word. He can't help but wonder why.

• Your actions hold a certain carefulness—he doesn't want to call it care, for when it comes to you, he finds it hard to tell what you're thinking—that he doesn't understand. As you wrap the gauze around the wound on his arm from a bullet graze, fingers touching his skin with a kind of gentleness he's only ever known from you… Dazai wonders when you'll finally tell him what you're really after.

• The brief thought occurs to him, no doubt, that maybe you do these things simply because you want to. That perhaps you still care too much, like you did all those years ago. But he knows better than to count on something as fickle as the kindness of people’s hearts. He was never that naive.

• Even so, as the long days and even longer nights pass by, he can't help but once again start feeling as he used to in the distant past, only that this time he has no excuse for it.

• Dazai doesn't blush and his heart doesn't race when he sees you. Instead, it's something far more sickening and confusing. With you, it's easier to drop the delicate layers of pretense that seem to obscure his true thoughts and emotions like delicate gauze. There is a sort of ease of being around you, a sense of belonging. In the delicate moments of the late night hours with you, humanity doesn't simply feel like a cloth to wear to hide the rotten core within. You touch him like you know him, even when he knows that the blood staining his hands is far darker than yours.

• You don't even have an inkling of how he feels, and Dazai believes that it's for the best. He’ll tell you in the future, if he can grow to trust you. He wants to say it when he can be sure of it, in a more peaceful time. Even if he doesn't want you to slip through his fingers again like he did in the past, he wants to wait.

• But right now, all he can see is your bloodied fingertips trembling in the aftermath of the day’s chaos, barely having escaped with your lives. In the silent night, neither of you mention how he holds your hand silently on the walk home, bandaged fingers holding yours with deliberate care.

[octagava]

Headcanon time, because of course, I need to ramble.

Dazai's hair was black during his time in the Port Mafia, but not because it was his natural color. It was a reflection of his own neglect. He didn’t take care of himself, rarely going outside during the day, and when he did, it was only in dark alleys. His hair was greasy, unwashed, and full of dirt, sticking to his scalp. God knows how much old dried blood remained in it as well...

It was only after leaving the Mafia that he began somewhat caring for himself, even if only a little bit. He still struggled with it (God knows depression was hard on him), but it was still better than his days in the PM. It was an improvement. Over time, his hair actually grew quite healthy, regaining its softness. The black color was gone, replaced by a warm shade of brown, and his curls regained their natural bounce, framing his face.

He actually looked healthy.
