Summary
Dazai Osamu never joined the Port Mafia, nor did he ever become a member of the Armed Detective Agency.
No one had ever heard the name Dazai Osamu.
At least, not until a report came in from the police.
So who will find Dazai Osamu first?
The Armed Detective Agency?
The Port Mafia?
Or the organization that's been hunting him all along? -

Summary
No one ever truly knew anything complete about Dazai.
Everyone picked up fragments here and there—small pieces of information, scattered hints—but even when those fragments were put together, they barely formed a quarter of the full picture.
And when an ability began showing Dazai’s memories to both the Armed Detective Agency and the Port Mafia, things quickly spiraled out of control.

Summary
Peter Parker, who lost his family at thirteen, is “adopted” by Tony Stark—but the Stark Tower never truly becomes his home. Harley is everyone’s golden child; Peter is the quietly forgotten kid. No one notices his intelligence, his trauma, or how much he has changed.
After testing the powers he gained from the spider bite on his own, Peter goes unheard for years. Finally, at seventeen, he hacks the SHIELD system and calls Nick Fury.
Perhaps this time, someone will actually listen.

Summary
In his panic, Chuuya hadn’t considered that this might’ve been an accident. After all the times he’d had to fish Dazai out of various suicide attempts, it was practically second nature to him now.
But this Dazai was just a baby.
In that case, Chuuya was surprised the baby wasn’t wailing with how jarring of a wake up that must’ve been.
No, he wasn’t wailing, but his eyes were wide with terror, breaths coming fast, and his bottom lip quivered along with the rest of him.
OR Chuuya brings a deaged Dazai home with him, where everything continues to go wrong

Summary
“Dazai-san watch out!” Atsushi shouted, his voice drowned out by the roar of the ability.
The tendrils struck Dazai too, the aftershock of the blast dragging him into the chaotic void. Even though the source hadn’t directly touched him, Dazai felt nauseous, stuck in a cycle of being pulled in and his ability pulling him out, the dark energy dragging him under.
The world around them faded to black. The sounds of the city, the panicked screams of the civilians, the clatter of battle—it all vanished, replaced by an eerie, oppressive silence.or
The ADA and port-mafia go on a mission and things go horribly wrong

Summary
“Dazai hasn’t said a word since the ability activated.”
Chuuya’s blood ran cold. He returned his gaze to the miniature Dazai, and felt his chest clench.
Even though he had to be terrified, Dazai sat stiffly on Naomi’s lap. His face showed no fear, just a blank stare that was all too familiar to Chuuya. He looked like a lifeless doll with no agency of its own.
“Dazai, do you know who I am?” Chuuya asked, keeping his voice even.
OR Chuuya gets hit by an ability, turning Dazai into a baby & leaving Chuuya to take care of him

Summary
“I never thought the real sun would be so warm,” Dazai murmurs from the backseat. In the rearview mirror, Chuuya watches Dazai press his cheek adoringly against the window. A snake coils in his stomach.
This wasn't what he expected when he was told to pick up his boyfriend from work.
In which Dazai is transformed into a traumatized nine-year-old, and while no one can resist peering into the cracks in his psyche...
No one expects who peers back.
(Chapter 2 reuploaded with edit and updates!)
