Chapter Text
Dazai Osamu is 22 years old, standing in a hallway he used to call home. The Port Mafia headquarters hasn't changed in the four years since he left it. That's the first thing he notices, stepping through the front doors with Kunikida on his left and Fukuzawa a half pace ahead—the same marble floors polished to an unnerving shine, the same portraits of men long dead lining the walls like a gallery of ghosts, the same cloying smell of expensive cologne and gun oil that no amount of ventilation ever seemed to clear. He remembers hating that smell as a teenager. He remembers, more distantly, learning to stop noticing it at all, the way a person stops noticing the sound of their own heartbeat.
He notices it now.
"You don't have to do this," Kunikida says, low, for what might be the fortieth time since this morning. His jaw is set in that particular way it gets when he's already lost an argument and refuses to accept it, notebook clutched tight enough in his hand that Dazai can see the give in the leather cover. "There has to be another way. Some other arrangement, some—"
"Kunikida," Dazai says, and doesn't finish the sentence, because there isn't one to finish. They've had this conversation. They've had it every day for the past two weeks, ever since Fukuzawa called an emergency meeting and told them, in that flat unreadable voice of his, exactly what favor the Port Mafia intended to collect. There is no other arrangement. There was never going to be.
The hallway opens into the Mafia's main audience hall, the room reserved for business too formal for Mori's office and too important for anywhere else, all soaring ceilings and dark wood and a long red carpet that Dazai used to walk down as a teenager with his hands folded behind his back like a good soldier. It's already full. He counts without meaning to, some old instinct clicking back into place before he can stop it; Kouyou near the front in pink, expression carved from something colder than stone; Akutagawa a few steps behind her, black coat, eyes fixed somewhere over Dazai's shoulder like looking at him directly might cost something; Higuchi hovering near Akutagawa's elbow, jaw tight. Gin, silent as ever, positioned at the edge of the room where she can watch every exit.
And Chuuya.
Chuuya is standing dead center, arms crossed, hat low over his eyes, and Dazai doesn't let himself look for more than a second. That's the rule he made for himself in the car. Look, catalog, move on. Anything longer than a second and he isn't sure what happens, only that it wouldn't be good, wouldn't be controlled, and control is the only thing he has left to offer this room.
Mori is seated at the head of it all in a high backed chair that isn't quite a throne but wants badly to be one, hands folded, smile already arranged on his face like he's been sitting there rehearsing it. Elise is nowhere in sight. Small mercy. Dazai doesn't think he could stomach her voice today, doesn't think he could stand to hear something so bright and unknowing in a room about to be handed over, a debt collected. Behind him, he hears the rest of the Agency filing in—Ranpo's footsteps, uncharacteristically even, none of his usual bouncing gait; Yosano's heels striking the marble hard enough to echo, a sound like something building toward a detonation; Kenji's breathing, too loud, the way it gets when he's trying not to cry and failing at the trying. Atsushi doesn't make a sound at all, which is somehow worse. Dazai doesn't turn to look at any of them, he's not sure his face would hold if he did.
Fukuzawa steps forward alone, the picture of composure he's built a career on, and inclines his head with exactly the amount of respect the occasion demands and not one degree more. "Mori-san," he says. "We're here to honor the terms of the arrangement."
"Fukuzawa." Mori's voice carries easily across the hall, honeyed and warm, the same voice Dazai grew up being soothed and threatened by in equal measure, sometimes in the same sentence. "So formal! We're practically family, you and I. Weren't we drinking companions, once upon a time?"
"That was a long time ago."
"Was it?" Mori's smile doesn't move. "It doesn't feel so long to me."
Dazai keeps his eyes forward, keeps his spine straight, keeps his hands loose and open at his sides because the boss taught him once, a lifetime ago, that a man who clenches his fists in a room like this is a man announcing exactly how afraid he is. He isn't afraid. He tells himself that with the same flat conviction he uses to tell himself a great many things that aren't true, and waits for Mori's eyes to find him. It doesn't take long.
"Dazai-kun." Mori says his name like he's savoring it, like it's a wine he's been cellaring for years and has finally decided is ready to drink. "Come here, won't you? Let's not keep everyone waiting."
He walks. That's the part that will stay with him later, he thinks, not the room, not the silence, not even the look on Chuuya's face that he refuses to let himself really see. It's the walking. The way his legs simply carry him forward across that long red carpet without waiting for his permission, the way four years of relearning how to be a person with wants of his own collapses instantly back into the shape of someone who was trained, from the age of fourteen, to obey a summons the moment it's spoken. Some part of him had hoped that part of him was dead. It clearly isn't. It was only sleeping. He stops a respectful distance from Mori's chair and inclines his head, not quite a bow, and behind him he hears Yosano make a small, furious sound that she swallows before it can become a word.
"There," Mori says, pleased, as if Dazai is a dog that's performed a trick correctly. "Now. I believe there's a formality to observe."
Fukuzawa's voice, when it comes, is quiet enough that Dazai has to strain to hear it over the ringing in his own ears. "The Armed Detective Agency acknowledges the debt incurred to the Port Mafia during the incident eleven months prior, and agrees to its resolution as specified: the permanent transfer of one member's service and loyalty, at the receiving party's discretion." A pause, long enough that Dazai can hear exactly how much it costs him to keep going. "The receiving party has named Dazai Osamu."
"Wonderful." Mori claps his hands together once, softly, like this is a party trick. "I do so appreciate when people honor their word."
"There has to be some other—" Kunikida starts, voice cracking with the effort of staying level, and Fukuzawa doesn't even turn around, just lifts one hand, and Kunikida goes silent so abruptly it must hurt.
"There's nothing more to negotiate," Fukuzawa says, and Dazai can hear, underneath the calm, something that might be grief, might be guilt, might be both wound so tight together there's no separating them anymore. "The terms were set. We agreed to them because the alternative was worse. I'm sorry, Kunikida-kun. There's nothing I can do."
Nothing I can do. Dazai examines the words from every angle the way he might examine a stranger's alibi, and finds, disappointingly, that they're true. Near the front of the hall, Kouyou hasn't moved, hasn't spoken, hasn't so much as shifted her weight since Dazai walked in—but he's known her long enough, watched her carefully enough as a child learning which adults were safe to provoke and which weren't, to read the stillness for what it is. It isn't indifference. It's the specific, deliberate stillness of a woman who has decided, a long time ago, that showing anything in this room would only be handing Mori a second thing to enjoy. Her eyes flick once, toward Chuuya, assessing, gone again before anyone but Dazai would have caught it, and something in the set of her mouth tightens fractionally before smoothing back into practiced neutrality. She doesn't look at Dazai at all. He isn't sure if that's mercy or its opposite. Fukuzawa isn't a man who lies about the shape of his own helplessness. If there had been a door out of this, he would have found it. He'd spent eleven months looking, Dazai knows, because Dazai had spent those same eleven months watching him look.
Behind him, Ranpo says nothing at all. Ranpo Edogawa, who has an answer for everything, who solved the impossible before breakfast on a slow Monday, who has never once in the whole of Dazai's memory looked like a man without a plan; Ranpo is standing there with his hands loose at his sides and his usual half lidded smile nowhere on his face, and for the first time since Dazai has known him, he looks exactly like what he is: A man watching something happen that he can't outthink his way out of.
"There's no trick," Ranpo says, quiet, almost to himself, like he's still testing the sentence to see if it holds. "I checked. There's no trick to this one."
He says it again, a beat later, softer, like repetition might change the answer if he just runs the numbers one more time. "There's no trick." A pause. "Dazai. There's no trick."
Dazai doesn't look at him. He can't afford to. If he looks at Ranpo right now, genuinely lost for the first time in his life, hands empty of the one thing that's ever made him feel safe in a room like this, he thinks he might do something unforgivable, like beg.
"Dazai." Yosano's voice, when it comes, isn't quiet at all. It cuts across the hall like a blade unsheathed, and Dazai can hear, underneath the fury, the particular pitch of someone holding themselves back from violence through sheer force of will. "This is insane. You are not—" She stops, then starts again. "He is not property. You cannot just hand a person over like a—like an asset on a ledger, like he doesn't have a say in his own—"
Somewhere near Kouyou, Akutagawa's head turns sharply toward Yosano, and for a moment Dazai thinks he might actually speak; his jaw works, some argument or agreement caught behind his teeth, eyes flicking briefly, involuntarily, to Dazai's face before dropping again like the contact burned him. He doesn't say anything. He never does, not in rooms like this, not where Mori might hear it and remember it later. But his hand, Dazai notices, has drifted into a fist, knuckles pale, and Higuchi beside him has gone very still, watching him instead of the ceremony.
"Yosano-sensei." Mori's tone doesn't change, doesn't sharpen. "I do admire your passion. Truly. But I'm afraid the terms are the terms. Dazai-kun agreed to them himself, didn't he?"
He did. That's the part none of them want to sit with, not Kunikida, not Yosano, not even Fukuzawa, who knows better than anyone what it looks like when Dazai decides something and refuses to be talked out of it. He'd volunteered before Mori could even finish laying out the terms of what the Agency owed. He remembers the look on Fukuzawa's face when he said it; a terrible, weary sort of understanding. He'd told himself it was strategy. If it had to be someone, better him than Kunikida, whose rigidity would shatter inside these walls within a month. Better him than Atsushi, still soft enough at the edges that the Mafia would carve him down to something unrecognizable in a year. Better him than anyone whose absence would leave a hole the Agency couldn't survive losing. He is, by every calculation he ran, the only member expendable enough and durable enough to be handed back to the wolves and come out the other side still breathing.
He hadn't let himself think, not once, about the promise he was breaking to make that calculation. Not until he was standing in this hallway with its unchanged marble floors, and it came rushing back all at once; Odasaku's voice, quiet and certain in a way that Dazai had spent four years trying to be worthy of. Live like a human being. Become a good man. Leave this place and don't come back to it. Sorry, Odasaku. He'd rather break that promise than watch someone else pay a debt that was, in every way that matters, his to owe.
"He agreed," Mori says again, softer now, gentle, "Didn't you, Dazai-kun?"
"I did." His own voice sounds strange to him, flattened out, like it's coming from somewhere down a long hallway rather than his own throat. "Nobody forced my hand."
That isn't entirely true. Nobody held a gun to his head, no. But there's more than one way to force a hand, and Mori has always understood that better than anyone Dazai has ever known; how to construct a situation so precisely that the only rational choice left is the one you wanted all along, how to make cruelty look, from every conceivable angle, like somebody else's decision.
Yosano's hands curl into fists at her sides. Kenji makes a small, wounded sound, quickly muffled. And somewhere behind him—he doesn't turn, doesn't dare turn, but he hears it, the particular creak of leather gloves flexing tight around a closed fist—Chuuya says nothing at all. That silence is the loudest thing in the room.
"Well then." Mori rises from his chair, smoothing invisible wrinkles from his coat with the satisfied air of a man closing a business deal that went exactly as planned. "I believe the formalities are concluded. Shall we make it official?"
He gestures, and one of the junior members steps forward carrying something folded across both arms; black fabric, Dazai recognizes it before it's even fully unfolded, recognizes the cut and the weight of it from a lifetime ago, because it's the same coat every ranking member of the Port Mafia wears, the coat he wore for four years and told himself, when he left, he would never put on again. Mori takes it himself. That's a deliberate choice, Dazai knows, he could have had anyone drape it over him, some junior officer performing the ceremony while Mori watched from his chair, but Mori has never once in his life passed up an opportunity for theater when the stakes were this high.
"Dazai-kun." He steps close, closer than strictly necessary, and Dazai holds himself perfectly still the way he was trained to as a child, the way a body learns not to flinch even when every instinct screams to. "Welcome home."
The coat settles over his shoulders and it's heavier than he remembers. Or maybe he's just weaker than he used to be, softer, four years of being allowed to want things and have friends and sleep without one eye open having worn down whatever calluses let him carry this weight without noticing it. It smells like cedar and gun oil. He doesn't reach up to adjust it. Doesn't shrug his shoulders to settle the fabric the way he used to, automatically, so so long ago. He just stands there and lets it hang on him, foreign and horribly, sickeningly familiar all at once, and somewhere behind him he hears Atsushi's breath catch. He turns, before he can think better of it, and finds Atsushi's face; pale, stricken, eyes too bright, and does the only thing his hands seem to know how to do in this moment, which is reach up and shrug off his own coat, the beige one, the one Atsushi has seen him wear every single day, and hold it out.
"Here," he says, and his voice comes out almost steady. "Look after this for me, would you? I have a feeling I won't be needing it where I'm going."
Atsushi takes it like it might break. His hands are shaking. "Dazai-san—"
"Take care of the Agency," Dazai says, quieter, just for him to hear. "That's an order, Atsushi-kun. The last one I get to give you for a little while."
Just past Atsushi's shoulder, Kyouka has gone very white, one hand fisted in the hem of Atsushi's sleeve like she means to physically hold him back from whatever he might do next, or perhaps to hold herself back from doing it first. She doesn't say anything either. Dazai remembers, distantly, a version of her that used to be a weapon with no say in where it was pointed, and thinks she understands this moment better than anyone else standing in this hall, understands exactly what it is to be handed from one owner to another and told to call it an arrangement. Her eyes meet his for half a second, quietly sad, before she looks away. He doesn't wait to see Atsushi's face crumple. He can't. If he watches that happen he isn't sure the mask holds, and the mask is the only thing standing between him and every member of this hall watching Dazai Osamu fall apart in real time, and he refuses—he refuses—to give Mori that satisfaction today of all days.
So instead he turns back around, coat final on his shoulders, and lets himself, finally, for one single unguarded second, look at Chuuya.
Chuuya is watching him (Of course he is). Dazai doubts he's looked away once since Dazai walked into this hall; and his face is doing something complicated and furious and carefully, deliberately blank all at once. His arms are still crossed, his jaw is tight, and his hands…Dazai catches it only because he's looking for it, because some old instinct that never fully died knows to look for the tells under the performance; his hands are curled into fists inside those black gloves, knuckles standing out even through the leather, like it's taking everything he has not to move. They don't speak. There's nothing to say yet, not here, not in front of Mori and Kouyou and Fukuzawa and every single person in this room who would hear every word and turn it into a weapon. But Chuuya's eyes hold his for one long, unbearable second, and Dazai reads in them something he can't quite name something too dangerous to show in a room like this.
Mori's voice breaks the moment before either of them can decide what to do with it. "Chuuya-kun." He says it lightly, but there's an edge underneath, the sound of a someone who noticed exactly what just passed between them and intends to use it later. "Won't you show our new member to his quarters? I think he's had rather a long day."
For a moment, Chuuya doesn't move at all, then he uncrosses his arms and he says, flat and entirely without inflection, "Fine."
He turns without waiting to see if Dazai follows. Dazai does, because there's nothing else left to do, because the coat is already on his shoulders, and the ceremony is already concluded, and somewhere behind him he can hear Yosano's furious, hitching breathing and Kunikida saying his name like it might still change something, and Atsushi clutching a beige coat to his chest like it's the last piece of something he's afraid he's about to lose entirely. He follows Chuuya out of the hall, and doesn't look back once. He doesn't trust himself to survive it if he does.
