Summary
And so our tale begins—not only a story of the hard reality that shapes a child’s heart, but of the darker imagination that takes root in silence. This is the story of a boy’s lonely enchantment, of the world he sought in magic, light, and shadow, and of the fate that awaited all who lived within the Trancy house.
Follow Alois Trancy as he fights in a courts battle and soon lives his life happily fighting crime with Ciel phantomhive and Integra Vanhellsing.

Summary
nakahara cannot possibly be real. That’s the conclusion Dazai comes to as he lays in the couch stuffed into the corner of Yosano and Kunikida’s staff room. A guy that attractive, that custom built to all Dazai’s standards and preferences, is simply too specific and rare. Dazai is never that lucky.
Therefore it’s only logical that nakahara is not real.
Dazai tries to silence his mind, focus on preparing for his next class, but he can’t stop internally fawning about for nakahara. The simple, unavoidable fact is that he spent last night developing a parasocial admiration bordering on teenage crush for a stranger on Twitter.OR:
Depressed and exhausted master's student Dazai finds Chuuya on Twitter and falls in love with him. Also, poetry.
2024 UPDATE: edited for improvements, and i will be updating and completing this :)

Summary
Akutagawa does not understand why his Rashomon beast is going out of control every time she is around. She doesn't seem to know either, the only thing she is sure of is that she is getting addicted to Rashomon and fast.
PS: Rashomon is the best wingman anybody could ever have.
“Hello Rashomon..”
She whispered, extending her arm and Rashomon went in, slowly wrapping around her hand.
“God you are so beautiful.. I can feel that you wanna come to me, don’t you?”
Her attention was completely devoted to the black beast that she didn’t see the way Akutagawa blushed. He shook his head to get rid of his nerves that always seemed to invade his mind when he was around her.
“Shall we run away together?”
Her voice brought him back to this world.
“Nobody’s running anywhere with Rashomon. Don’t test your luck.”

Summary
(work title from c0mput4r by June Henry)
Eventually, Mori's office's door came up in front of them.
Fancy. Gaudy. Pompous. Another word.
Dazai elbowed them open, Chuuya muttering as he did so, walking into the room with a smirk. His single visible eye glinted dangerously in the light, matching Mori's perfectly.
...
The paperwork on the doctor's desk implied this would be a long mission.
Or:
Dazai and Chuuya get sent to Hogwarts age 15, force magical racists to be nice and discover how codependent they are.
...with some good old language and culture confusion at times. Because the idea of Dazai constantly being like 'yeah, no, call me by my last name or I find a brick to throw at you <3 is hilarious to me.

Summary
Seven years ago, Dazai dared Chūya into a blood pact—just a game between angry teenagers with too much power and too little sense.
It was supposed to fade.
But blood remembers.
Now Dazai is unraveling—unstable, half-dead, and calling for the one person who should’ve let him rot. The moment Chūya steps into that hospital room, something ancient reignites: pain, memory, magic.
The bond wakes.
And it wants everything back.

Summary
Chuuya Nakahara thinks his biggest problem is juggling schoolwork and his overbearing older siblings. At home, he’s the youngest in a loud, chaotic household where no one ever stops bickering—but where love runs deep, even if it’s buried under teasing and chores.
Dazai Osamu, meanwhile, lives in a very different kind of house. Mori Ougai, his guardian, is a doctor with strict expectations, and their quiet, tense home couldn’t be further from the Nakaharas’ noise.
When the two are paired together for a school project, Chuuya assumes Dazai is just a prickly genius who refuses to talk to him. But the more time they spend together, the more Chuuya begins to notice the cracks in Dazai’s carefully built walls—and to realize that maybe the weirdo genius isn’t so untouchable after all.
