    Summary

    “Tsushima Shuuji,” Chuuya reads out loud. “A bright, optimistic young man with a pep in his step and a zest for life. Hang on–is this referring to you?”

    “Unfortunately,” Dazai laments, sighing dramatically. “You just got away with ‘science nerd’ and ‘soccer player,’ but I’m supposed to be an artist! I hate art! It’s useless!”

    “Shut the fuck up. That’s not the problem here. You? A ‘zest for life?’ Looking forward to each new morning? Hah! Rimbaud would sooner come back to life.”

    Dazai turns to Chuuya with the barest facsimile of a smile painted over his lips.

    “I,” he says sweetly, “am going to gut you open like a fish.”

    Dazai and Chuuya are seasoned mafiosos at the ripe old age of almost-seventeen. They’ve fought gang wars, interrogated prisoners, and done all manner of unspeakable things. Now, they face their greatest challenge yet: going (undercover) to a real high school. With regular teens (who may or may not be desperately trying to get them to kiss).
    One thing’s for sure: this school is unprepared for the absolute calamity that is Double Black.

    Summary

    “Jesus Christ, Chuuya is going to kill this idiot for worrying him like this, for being a suicidal maniac who decided to put himself in the damn trajectory of a machine that they don't even know all the effects of yet.”

     

    When a stranger starts stealing people's abilities, the ADA and the Port Mafia team up to figure it out. However, something goes wrong and Dazai loses his ability in the process.

    The big problem? His ability not only nullified the abilities of others, but also his own emotions. And now, for the first time in his life, Dazai has emotions, chaotic and in turmoil. In the midst of this identity crisis, Dazai sets out to explore the world with Chuuya as his grumpy bodyguard, only to discover that he has never felt so...alive. And then they find out that if they don't find a way to give him back his ability, Dazai will die within two weeks.

    In a race against time, chaos ensues.

    Summary

    “What’s your problem?” Chuuya pressed. “You drink. You swallow whatever pills the Boss throws at you like candy. But one little joint and you’re acting like a grandma.”

    Dazai’s smile froze.

    “Chuuya,” Albatross said lightly, pushing himself up onto his elbows. “Maybe chill.”

    “What? I’m just saying,” Chuuya said. He turned back to Dazai, annoyance lighting his cheeks. “You’re the one acting like I’m about to shoot up heroin in front of a kindergarten. It’s weed. You already do every other drug under the sun.”

    The words hit harder than they should have. Maybe because they were true. Maybe because they weren’t, not in the way Chuuya thought. For a heartbeat, Dazai couldn’t hear the wind or the waves. Just the pounding in his own ears.

    Every other drug. Like it was a hobby. Like it was something he did for fun.

    “Chuuya doesn’t know what he’s talking about,” Dazai said, voice flat.

    or: Chuuya smokes for fun. Dazai takes drugs to die or because Mori tells him to. When a stupid joint on a hill turns into Dazai admitting the difference, Chuuya makes a new rule: if the Boss drugs you, you don’t go curl up alone. You come find me when it’s over.

    Summary

    Mori Ougai had worked hard to earn his position as head of the Port Mafia, and he ruled with absolute authority. And, like any other who wielded absolute power, he was not someone to take an affront lightly. He was even less inclined to forgive and forget when the affront was committed by a spandex-clad man who claimed to fight for peace above all else. So, when he found himself dangling by the collar at the hands of Japan’s Number One Idiot during what should have been a routine meeting, he couldn’t help but laugh.

    Finally. Something he could work with.

    -

    Chuuya had done a lot of batshit crazy things in his life–he’d taken out entire rival gangs with just Dazai at his side, he’d been betrayed by the people closest to him, and he’d even risen to be one of the most influential members of the Port Mafia before he even turned 16. But nothing could have prepared him for his next mission. A pro-hero? UA student? Him? And that bandaged freak was going to? What has the world come to?

    -

    Or Mori is attacked, so Soukoku is forced to go to UA, and Dazai wields emoticons like verbal nukes

    Summary

    During a forced social gathering at the Agency, Dazai manages to slip away after distracting his younger mentee with some elaborate excuse, seeking solace in the bathroom amidst a morbid encounter with the piece of deadly metal in his hands, contemplating.
    Chuuya watched him slip away. And he won't let it happen again.

    Summary

    He could’ve gone to Odasaku.
    He could’ve gone to Doc.

    He could’ve gone back to the container, thrown up until he passed out, and called it a night. He could’ve gone under the water and just waited. But his legs were already walking again. And they weren’t going toward any of those places.

    Dazai knew this part of the city too well. Knew the slant of the road, the neon buzz of the bar sign three blocks up, the iron stairs past the alley where the dogs always barked. He didn’t need to look up to know where he was going.

    He knew this part of the city because—

    Because it was where he lived.

    delirium drags dazai somewhere he didn’t mean to go. his body chooses chuuya for him.

    (or: he should’ve died on the way to the door. survival isn’t the mercy people think it is.)

    from S2E9:

    “Do you still wear the coat that I gave you?”
    “I burned it.”

    They’re the wrong words to say.

     

    Mori’s abuse runs deep—deeper than anyone, including Dazai, had realized. And he’s doing it all over again.

    Summary

    “Wh— hey, Rui!!”

    If Rui hears Tsukasa’s disbelieving exclamation, he doesn’t acknowledge it. His fingers drift down to the next button with no hesitation, unlooping the plastic effortlessly. Tsukasa swallows thickly as Rui’s shirt falls apart another inch.

    He can’t be that hot, right?? He’s hardly sweating. There’s no way he needs to take off the entire shirt. Especially because Rui’s naked upper body is absolutely the last thing Tsukasa’s focus needs right now—

    The thought dies in his brain when the fabric around Rui’s chest falls open.

    …is that lace…?

    ***

    tsukasa needs to study for his physics test! rui says he has a reward for him if he finishes his worksheet. surely nothing out of the ordinary will happen right???

    Summary

    Finally, Chuuya eloquently said, “I don’t want to date you.”
    Dazai huffed. “Yeah, well, I’m not too thrilled at the idea of having a crazy rockstar boyfriend. But you got us into this mess, you need to help us get out of it.”
    Had Dazai gone insane? Nakahara Chuuya and Dazai Osamu, dating? Had Chuuya not made it clear through the dozens of direct and indirect meetings that he despised Dazai with every fiber in his body.

    Featuring: drunk tweets, falling in love, horrendous song writing, cheesy interviews, learning how to "fake it," and Chuuya getting over the headache that is Dazai. Not necessarily in that order.

    Summary

    Best friends is too simple a term to squash the entire dynamic of Dazai Osamu and Nakahara Chuuya within.

    Sure, they’ve known each other since they were children, and they’re each other’s #1 on their best friend lists on Snapchat, and Chuuya’s been seen one too many times in his hoodies. People have also noticed how Dazai’s main muse for his volunteer hobby of polaroid photographer is the redhead himself.

    But the pranks they pull on each other isn’t much of a ‘best friend’ thing to do.

    Especially when one of the pranks get pulled so far,

    That Chuuya is forbidden from seeing Dazai ever again.

    And though he sees no good coming from such a forced separation, the one thing that can enhance their futures together is propelled forward at a faster speed than either of them could have ever imagined:

    Coming to terms with their unusual feelings for each other.

    Summary

    This was far from the first time Dazai spent time in a mental institution. The inpatient facility was more like a second home at this point. He wasn't expecting anything different from usual when he was admitted yet again. But a short redhead with anger issues had the potential to save Dazai from this monotonous torture.

    “Four months from now will be the seven year anniversary of when you and Osamu Dazai released your hugely successful first and only album Double Black and its diamond single Corruption. After performing with Dazai earlier this year, are you planning anything special to celebrate?”

    “Corruption is insanely overrated, and I would prefer to never hear Dazai’s voice for the rest of my fucking life.”

    Summary

    Dazai-centric, mostly canon one-shots all existing in the same universe. i.e. all the events in these fics are presumably in the same world and may be referenced in latter one-shots. My goal is to have 10 in total but who knows, maybe I'll make it to 20!

    ( ^◡^)っ ♡

    I've been recently reading the works of real-life Dazai so I like to sprinkle in some references and easter eggs along the way. I've also consumed a lot of BSD works (English fan translations) in a short period of time, so these one-shots reference:

    "Osamu Dazai and the Dark Era"
    "How I Picked Up Dazai" or "The Day I Picked Up Dazai" (Parts A and B - this is also my favorite light novel)
    "Beast" manga
    "55 Minutes" (my other favorite!)
    "Stormbringer"
    "Dazai, Chuuya, Age 15"
    "The Untold Origins of the Detective Agency"

    I'm up to date with the manga *cue all the soukoku heartache (╯°□°)╯︵ ┻━┻ * but I don't think I'll be incorporating recent chapters into these fics (though many a theory I have >>_>>)

    Summary

    In an attempt to sit back and unwind from a rather stressful day at work, Hirotsu takes his fellow mafiosos to a quiet bar he found in a desolate corner of Yokohama. Apparently, it's not desolate enough, as the Agency have also taken refuge in that very same bar. And Chuuya is starting to get undeniably pissed off at the prick flirting with Dazai at the bar.
    So, in his drunken rage, he hatches a plan to give Dazai a taste of his own medicine.

    This all makes complete rational sense in his own head, of course.

    Summary

    I don’t have a story on how it happens, but Snape and the Hogwarts staff has (somehow) rescued Dazai from the port mafia. In this story, he now knows about no longer human and he knows about Dazai being abused back in Yokohama.

    With his newfound freedom, Snape takes Dazai in and decides to finish raising him. It’s not as easy as he thought it would be, however. Dazai still has a ton of trauma weighing on him so Snape does his best to be a good “step in father” and help him through it.
