Summary
Look, Dazai didn’t choose to be a half blood
Just a few months ago he was at Elysian House, a run down orphanage that lived off the terror of children. (Not that he minded)
Now he’s apparently a demigod and has to navigate life at Camp Half-Blood. This was supposed to be a normal year!

Summary

Summary
Nakahara Chuuya doesn't think he can be considered a hero or a saviour, he isn't sure whether he qualifies as human. To Mori Ogai, this is the perfect opportunity to carry out an infiltration mission in UA, a pillar of Hero Society. Chuuya, having been thrust into this situation, executes his responsibility while understanding what it means to rely on others. The flags are more than happy to teach him this, in their own chaotic ways. Dazai, as always, believes all he can do is watch from the sidelines, although all humans are victims to desire.
Why does a simple mission seem to hold so much value? That's a question I don't have an answer to.This is pre-Stormbringer because I love the flags, and I find his character before his main development interesting.
If even one person sees this I'll be satisfied with myself. -

Summary
“Dazai. What the hell are you saying. Why?”
Dazai’s mouth opened, then closed again. He hadn’t thought that far.
Because you look uncomfortable. Because I don’t know how to help. Because I keep wanting to touch you and I don’t know where that impulse is coming from.
None of those felt safe to say.
“So Chuuya will stop being miserable,” Dazai said instead, defaulting to insult as camouflage.
Chuuya snorted. “You’re one to talk.”
Dazai glanced down. “I’m always miserable. It’s different.”
or: when chuuya doesn’t show up for a mission, dazai goes looking for him and does what he does best: pokes, prods, and pushes. but chuuya doesn’t need a fight, and dazai is left with the harsh reality that his confusing, inconvenient feelings don’t come with an instruction manual.

Summary
Twelve-year-old Osamu Dazai, severely depressed and openly suicidal, had been hospitalized for the past two months in one of Tokyo’s most prestigious rehabilitation centers—owned by his own father. The fact that his older siblings also worked there only worsened things, stripping him of what little privacy he had left. His life was lonely, colorless, and painfully controlled.
Until someone walked through the wrong door.
“Hey.” Dazai’s voice sounded unfamiliar even to his own ears. It had been a long time since he’d spoken to anyone. “This room’s taken, you’re in the wrong place.”
Chuuya’s eyes shifted toward the dark-haired boy. The defiant blue in his gaze softened into something more hesitant. “…Needles,” the child finally said. His voice was quiet, almost a whisper, as he tucked his face further between his knees. “They were going to give me an injection.”
-
Aka. Newly admitted to the hospital and running purely on survival instinct, Chuuya panics and accidentally stumbles into the room of Osamu Dazai, a suicidal menace and the rest is history.

Summary
“FUCK OFF!! LET ME GO!!!” Chuuya threw his head back and kept screaming on the hospital bed fought hard against the hands restraining him. The Port Mafia’s doctors and nurses —and Dazai, who was trying to keep him from using his ability, everyone was trying to calm Chuuya down. “DON’T YOU TOUCH ME, YOU SONS OF BITCHES! I SAID LET ME GO!!—”
He and Dazai had been sent on a special mission for the Port Mafia, and things went horribly wrong. As a result, Chuuya was raped and held captive by the enemies for three days. After the mafia team rescued Chuuya they took him to the Port Mafia hospital. He was in Mori’s medical ward. During the twenty-four hours he’d been in the ward, Chuuya had attempted suicide several times.
And now...
“BRING THE SEDATIVE!” Dazai ordered in a cold, cutting voice, as if issuing a single command rather than shouting. Intervention was necessary; the crisis had to be brought under control or Chuuya’s body would suffer more damage.

Summary
Two months earlier:
“Do you really want to raise our baby here, Chuuya? In this horrible, disgusting place?” Dazai’s voice was uncharacteristically raw as he sat beside his pregnant husband on the couch. For once, there was no sarcasm, no inconsistency—just helplessness. “Don’t you think Oda was right?”
And now…
The moment Chuuya pieced it all together in his mind, his body lurched with the reflex to retch. A deep discomfort burned in his throat as his nails dug into the skin of his own neck. He shut his eyes, struggling not to lose his sanity.
Dazai did it. The moment Chuuya gave birth, Dazai had taken their baby from him and fled the Port Mafia. He ran. He ran. He ran. He ran. He deceived Chuuya.
“Dazai…” Chuuya’s pupils dilated with sudden, shattering realization, and he screamed.

Summary
"Making plans as always, huh?" Dazai’s voice slithered out of the darkness. His bandaged hands were buried in the pockets of his black trousers, and as he descended the stairs with deliberate slowness, the glint in his eyes was nothing short of devilish delight.
"That voice..." Chuuya, chained to the wall with his arms shackled on both sides, narrowed his eyes the moment he recognized who it belonged to. He clenched his teeth, lifting his head against the weight of the chains as his gaze hardened.
"Beautiful. What a marvelous sight," Dazai finally stopped as he stepped into the light. The curve of his lips sharpened, and with a wide grin plastered across his face, he spoke as he took in his former partner’s pitiful state. "This outshines any ten-billion-yen masterpiece. Don’t you agree, Chuuya?"

Summary
Over two centuries ago, in the dawn of quirks, Yokohama closed itself off from the rest of the world, making a gigantic golden dome rise and envelop its entirety. No one is allowed to enter, and no one is allowed to leave. That is what the outside world believes, at least, until a young boy raised inside of the barrier gets a little too curious for anyone's good.
Now, the principal of UA has received an invitation for an exchange program with none other than Yokohama's school for the gifted, the Twilight Academy: A place where good and evil have put their differences apart and intertwined into something more.
One can only wonder what the students will witness once they set foot into the city. Yokohama might as well be an entirely different world from their precious hero society, and the darkness is doomed to consume the faintest lights.
They may return home unscathed, but with one less student, will they come out the same?

Summary
“Think about it… You're in a big media scandal… So am I. You are the Chuuya Nakahara, I'm the Osamu Dazai. If I start dating and the relationship lasts over 12 weeks then the media will be happy. If you start dating me then that'll be crazy enough for the media to ease the attention off of the Black Lizard’s break up. If you think about it, it's a win-win” Dazai finishes with a straight face.
Chuuya has to take a few minutes to process all the information. As much as he wants to complain and retort, it's actually a good move…
OR
yet ANOTHER very self indulgent bsd band au where Rockstar Chuuya! finds his band - The Black Lizards in a bit of a scandal, and so does Model Dazai!, the son of Mori Ougai, the owner of Mori Records…the best solution? They start dating.

Summary
He’s in the Mafia.
She’s in the Ada.
He’s gravity.
She can be too. She can be whatever she likes.
Do they hate each other? If you ask the two of them separately, they’ll say differently.
After all, hate is such a strong word.
It might have been used in the beginning, but that fire simmers out, and is replaced with something like a rivalry.
Friendly? Not so much.
Deadly? Well, the two together are deadly, that’s for sure.
Jane Austen. Ability: Sense and Sensibility. Dazai Osamu’s underling. No. Sister-in-Crime. And Chuuya Nakahara’s bane of his existence.
Well, that’s what he likes to say.
Even when they are forced to work together.
You’ll find out the rest soon enoughTITLE PREVIOUSLY “Magpie” :)

Summary
Dazai Osamu is always prepared. Whether it be exams, tests, assignments, or whatever else life chucked his way, but what he wasn’t prepared for was wishing that a certain redhead liked him back. For all his life, Dazai Osamu wanted to die, but when he met a fiery-haired, brash, and oh-so beautiful Nakahara Chuuya, he thought he might as well give life a try.
OR
An AU where Chuuya stumbles into Dazai in the halls of their university and stains a bit more than just the mackerel’s journal.

Summary
Ever since he was a young boy, Osamu had heard many tales from wandering adventures, speaking of riches that put even the king himself to shame, medicinal herbs that could cure the fatalest of injuries and strong beasts that ruled where humans once did. Of course, being the intelligent child he was, Osamu never believed any of these tales. Adventurers had a tendency to twist even the smallest of encounters into the greatest of legends; he had fallen victim to these exaggerated truths more than once.
However, this time was different. Numerous formidable adventuring parties had been going missing in the mountain range a few kilometers west of his current guild, unmapped lands; those who returned spoke of dangers beyond anything they had ever seen, warning fellow adventurers not to explore the mountains, no matter the riches that may lay beneath its death ridden grounds.

Or an alternate universe where the dragon Nakahara Chuuya meets the insufferable wizard Dazai Osamu.

Summary
“You’d better not go,” Dazai says, and like the little imp that he is, he gives Ango’s shoulder another jab with his horn. “Without you around, who am I supposed to torment?”
Ango lets out a huff, though there’s no venom behind it. “I have half a mind to exorcise you.”
“Good luck with that!” Dazai pulls back to reveal a mischievous grin. “I was actually deemed Most Difficult to Exorcise by the people of Yokohama. Of course, most of them were hacks with only a tiny bit of supernatural awareness. A genius on your level of sleep deprivation hasn’t been seen in the last three hundred years. You might just stand a ghost of a chance!”
Ango has both a guardian angel and a demon of temptation. It is his infinite misfortune that they get along with each other so well and are now conspiring to make him go to sleep.
(In which Dazai tries to avoid work at every turn, Oda is an enabler, and Ango just wants random supernatural beings to stop invading his personal space.)
