Chapter Text
It was supposed to be a simple negotiation.
The Armed Detective Agency and the Port Mafia had agreed to a temporary truce—one of those fragile, grudging arrangements that neither side fully trusted but both recognized as necessary. A mutual enemy was making moves in Yokohama's underworld, someone who didn't respect the established borders between light and dark. Mori had proposed a joint information exchange. Fukuzawa had reluctantly agreed. Neither of them was happy about it, but both were too pragmatic to let pride get in the way of survival.
The meeting was held in neutral territory—a conference room in a building neither side owned, on a floor that had been empty for years. The Port Mafia brought Mori, Koyo, Chuuya, Akutagawa, Higuchiand Hirotsu. The Agency brought Fukuzawa, Ranpo, Dazai, Kunikida, Yosano, Atsushi. Everyone was on alert, watching the opposite organization's members closely.
Despite everything the meeting was going smoothly, until the door opened.
No one saw the person slip in. They were fast—trained—dressed in nondescript clothes that could have belonged to either organization or neither. They moved through the room like a shadow, and before anyone could react, they were behind Dazai's chair.
The person was hiding a syringe under his jacket. He lifted it and reached for Dazai.
"Daz—" someone started to shout, but it was too late. The needle was already in Dazai's neck. The plunger was already down.
Akutagawa's Rashomon moved first. Black tendrils shot across the room and wrapped around the intruder, slamming them against the wall. Kunikida was on his feet, his notebook open. Chuuya had his hand raised, gravity rippling around his fingers. Atsushi was half-transformed, tiger stripes rippling across his skin.
But the intruder was already smiling.
"Too late," they said, and then their body went limp. They had broken the poison capsule. Cyanide. Standard procedure. They were dead before they hit the floor.
The room erupted. Chairs scraped back. Someone shouted about the exits. Kunikida was already at the door, testing the handle. It didn't budge.
"What the hell—"
"Who was that—"
"Check the exits—"
"Everyone stay where you are—"
Kunikida pressed his ear against the door. Listened. His face went pale.
"Locked," he said. "Sealed. We're not getting out."
Dazai hadn't moved.
He was still sitting on his chair, one hand pressed against his neck where the needle had gone in. His face was pale. His eyes were open but unfocused, like he was trying very hard to process something his brain didn't want to accept.
Yosano was already moving. She pushed through the crowd and knelt in front of Dazai, her medical bag open, her hands already reaching for his wrist to check his pulse.
"Dazai," she said, her voice sharp but not unkind. "Are you in pain? Are you well?"
"Yes," Dazai said. "It burns. The injection site. And my head feels wrong. Like something is pressing against the inside of my skull. I am not well. I feel terrible."
Everyone had expected a deflection or a joke. A dismissal. Something like I've felt worse, dear doctor, but your concern warms my heart.
Instead Dazai had been 100% honest.
The serum had removed Dazai's most precious talent.
Lying.
The room went quiet.
Yosano's hands stilled on his wrist. She looked over her shoulder at Ranpo.
Ranpo was already staring at Dazai with an expression that no one in the room had ever seen on his face before. Something close to fear.
"Truth serum," Ranpo said. His voice was quiet. Controlled. "Someone injected him with a truth serum."
The words landed like a bomb.
"Dazai," Ranpo took a step closer. His glasses were on. His hands were in his pockets. His posture was deliberately casual. "Who am I?"
Dazai looked at him. "Ranpo Edogawa. Japanese. 26 years old. You're the greatest detective in the world. You're also insufferably smug and you eat too much candy. Your deductive abilities are genuinely extraordinary but you use them to avoid doing actual work whenever possible. I respect you more than I've ever told anyone."
Ranpo's jaw tightened.
He didn't need to ask another question. He already knew.
Everyone," Ranpo said, turning to face the room. "Nobody ask him anything. Not a single question. Not about work. Not about the past. Not about anything personal."
Atsushi's hand shot up, his face a mixture of confusion and concern. "Why not?"
Ranpo's eyes flicked to him.
"Because Dazai," Ranpo said slowly, "has spent his entire life building walls. And those walls are gone right now. Every question you ask, he will answer honestly. And some questions—" His eyes moved to Chuuya, briefly. "—should not be answered in a room full of people."
Chuuya's eyes narrowed. "What's that supposed to mean?"
"It means," Ranpo said, "that you need to keep your mouth shut."
"Truth serum." Mori said. His voice was calm, but his eyes were sharp. He was already leaning forward in his chair, his fingers steepled beneath his chin, his gaze fixed on Dazai with an intensity that made the air feel heavier. He was analyzing. Cataloging. His mind was racing behind those calm eyes, and everyone who knew him could see it.
Dazai looked at him and something flickered across his serum-exposed face. Wariness. The old instincts were kicking in. He knew that look. He'd been on the receiving end of it for years.
Ranpo took a step forward, positioning himself between Mori and Dazai. His glasses were on. His hands were in his pockets. His posture was casual, but there was steel underneath.
"Mori," Ranpo said. "I know what you're thinking. Don't."
Mori's smile didn't waver. "I'm sure I don't know what you mean, detective."
"You're thinking about all the questions you've never been able to get answers to," Ranpo said flatly. "All the secrets Dazai took with him when he left. All the information you could extract right now, while he can't lie. You're calculating the value of every question you could ask."
Mori's smile widened. Just slightly. Just enough to be unsettling. "And you aren't?"
Ranpo's jaw tightened. He opened his mouth to respond, but before he could, another voice cut through the room.
"Mori-dono."
Fukuzawa.
He hadn't moved from his position against the wall. His arms were crossed. His face was impassive. But his voice—his voice carried the weight of someone who had spent decades learning how to command a room without raising it.
Mori turned to look at him.
"I understand your curiosity," Fukuzawa said. "And I understand your instincts. But Dazai is a member of my Agency now. And we are currently operating under a truce."
Mori's eyebrows rose. "You're asking me to ignore a strategic opportunity?"
"I'm telling you," Fukuzawa said, "that out of respect for our alliance—temporary as it may be—you will not ask him questions. And neither will your subordinates."
The room held its breath.
Mori and Fukuzawa stared at each other across the conference table. Two leaders. Two men who had built empires through very different means. The tension between them was almost visible, crackling in the air like static before a storm.
Then Mori inclined his head. A small gesture. Almost regal.
"Very well," he said. "Out of respect for our alliance." He turned to face the Port Mafia side of the room. His voice was calm, measured, but there was an edge to it that made his meaning clear. "No one under my command will ask Dazai-kun any questions. Is that understood?"
Koyo's fan moved. A small, graceful acknowledgment. She understood perfectly.
Hirotsu nodded.
Akutagawa's jaw tightened. He didn't look happy. His eyes kept drifting to Dazai, then away, then back again. But he nodded.
Higuchi looked relieved. She didn't want to be here for this. She didn't want to hear whatever Dazai might say.
And Chuuya—
Chuuya's face was unreadable.
His arms were crossed. His shoulders were tight. His eyes were fixed on Dazai with an intensity that made the air around him feel heavy. He wasn't nodding. He wasn't agreeing. He was just—waiting.
Mori's gaze landed on him.
"Chuuya-kun," His voice was pleasant. It was also a warning. "Do you understand?"
Chuuya's jaw tightened. His hands clenched on his arms. For a moment, it looked like he might argue—might push back, might say something that would shatter the fragile peace of the room.
But then his shoulders dropped. Just a fraction.
"Understood," he said. His voice was rough. Flat. It didn't sound like understanding. It sounded like someone putting a cork in a bottle that was about to explode.
Mori studied him for a moment longer. Then he turned back to Fukuzawa.
"Your move, Fukuzawa."
Fukuzawa nodded. He turned to the Agency side of the room. "Out of respect for your colleague you won't ask questions. Whatever you want to ask—whatever curiosity you have—it can wait."
Kunikida and Kyouka nodded. "Of course, president" said Kunikida, adjusting his glasses.
Yosano's arms were crossed. Her expression was unreadable. She HAD something she wanted to ask him. But she nodded.
Atsushi raised a tentative hand. "But—but we need to know how long it lasts, right? Or if he knows who did it- harmless questions..."
"Fine," Ranpo said. "Harmless questions only. Nothing personal."
Yosano turned back to Dazai. "How long will the serum last?"
"I don't know," Dazai said. "I can feel it fading already but it's slow. An hour, maybe two. Possibly less. I hope less."
"Who sent that person?" Ranpo asked.
"It's probably one of Fyodor's men. He wants to expose my secrets."
"How can we get out of this room?" Chuuya asked Dazai. It seemed like that wasn't the only thing he wanted to ask.
"It's possible it will open once the serum is gone."
"How many languages do you speak fluently?" Kunikida asked. For some reason, his notebook was open on a page called Dazai's work skills.
"5. Japanese, English, French, Russian, also a bit of Italian."
Everyone stared at Kunikida.
"What?"
"Kunikida how is this relevant?" Yosano raised her eyebrows at the idealistic man.
"Well, he always lies about his skills, at least now we know he can speak other languages."
"That's impressive Dazai-san." Kyouka said.
"Thanks Kyouka."
"Does it hurt?" Atsushi suddenly asked quietly.
"Yes," Dazai said. "But I've felt worse. I've felt much worse. This is nothing compared to—" He stopped. His mouth snapped shut. His eyes went wide.
Ranpo was already moving. "No more questions. I said no more questions."
"But he was about to—" Atsushi started.
"I know," Ranpo said. "That's why we stop."
The room settled into an uneasy silence. Dazai had moved. He was standing now — pressed against the far wall, apart from everyone else, like he was trying to keep himself separate.
The dead intruder was pushed into a corner. The exits remained sealed. Everyone was watching everyone else, and everyone was very carefully not looking at Dazai.
Everyone except Chuuya.
Chuuya hadn't taken his eyes off Dazai.
He was standing with his back against the wall, arms crossed, face unreadable. His jaw was tight. His hands were clenched. His eyes—those blue eyes that everyone in the room had seen burn with fury a hundred times—were fixed on Dazai with an intensity that made the air between them feel heavy.
Ten minutes passed.
Ranpo watched him. He didn't say anything. He just watched.
Twenty minutes.
Chuuya's jaw tightened further. His hands unclenched. Clenched again. He pushed off the wall. Walked to the other side of the room. Leaned against a different wall. Crossed his arms again.
He was restless. Agitated. His eyes kept finding Dazai no matter where he stood.
Thirty minutes.
Mori was watching now too. His expression was calm, but his eyes were sharp. He knew Chuuya. He'd known him for years. He could see the storm building behind those blue eyes, could see the way Chuuya was fighting with himself, could see the question forming on his tongue even though he wasn't speaking it.
Forty minutes.
Chuuya's breathing had changed. Faster. Shallower. His hands were shaking. He shoved them in his pockets. Pulled them out. Shoved them back in.
Everyone in the room could feel it now. The tension. The anticipation. The sense that something was about to happen.
Ranpo took a step toward him.
"Chuuya," he said. His voice was low. Careful. "Don't."
Chuuya didn't look at him. His eyes were still on Dazai.
"Chuuya." Ranpo said again. Louder this time. "I'm warning you. Whatever you're thinking about asking—"
"You don't know what I'm thinking," Chuuya said. His voice was rough. Strained.
"Yes, I do," Ranpo said. "I always do. And I'm telling you—it's not worth it. Not here. Not like this. Not in front of everyone."
Chuuya's jaw tightened. His hands curled into fists at his sides.
"Let me handle this," Ranpo said. "When the serum wears off—when we're out of here—you can ask him anything you want. In private. Not here. Not now."
Chuuya was quiet.
He looked at Ranpo.
Then he looked at Dazai.
Then he looked back at Ranpo.
And then—because he was Chuuya, because he was stubborn, because he had spent seven years wondering what Dazai really thought of him and he was tired of not knowing, because forty minutes of silence had felt like five years and he couldn't take it anymore—he opened his mouth.
"What do you really think about me, Dazai?" asked Chuuya.
Ranpo's hand shot out. "Chuuya, don't—"
But it was too late.
The words were already out. And Dazai's mouth was already opening.
Chuuya will regret making that question for the rest of his life.
"You are the most irritating individual I have ever met, you are insufferable—"
Chuuya laughs a little looking at Ranpo. "See, four eyes, there is nothing to be worried about—"
"—but I still can't help loving you."
Chuuya's smile falters slightly.
WAIT..WHAT?
"It's inconvenient, and annoying, really."
He took a breath before continuing.
"Since the first moment I saw you seven years ago I have been drawn to you. I was immediately enchanted by you, by your strength - physical and mental. "
He looks away. Like he's embarrassed to be saying this out loud.
"You made me want to live. Meeting you was one of the few good things that happened to me in this life."
Dazai laughs a little.
"I wanted to know more about you. What was an initial teenage crush then turned into love, but I only realized my feelings after leaving you behind. You are beautiful, strong, intelligent - even if less than me - unbreakable."
"I like you not for your ability, as Fyodor thought, but for your loyalty. I really don't understand how a wonderful human like you is still by my side, when all I have ever been with you is a piece of shit. Because you ARE human, Chuuya. I have never doubted that for a single second."
"There's no way I could love a man-made character string this much."
His eyes linger on Chuuya for a moment too long, before he looks away again — like he's memorizing him. Like he's not sure he'll ever get to look again.
Chuuya's breath catches. Just slightly.
"And even though I know you despise me I can't help but think of you. I like to imagine a world where our lives are different, without burdens to carry or abilities, or cities to defend. And I wonder if in that world I could have happily stayed by your side and perhaps started to appreciate life."
His eyes are distant, almost dreamy. Like he's looking at something he knows he can never have.
"I have been in love with you for 7 long years, but if I told you, you would think I am messing with you."
"Your ability is undoubtedly gravity manipulation because there will always be a force that attracts me to you. And there is no nullification that can save me here."
"Sometimes I miss you, but I would never admit that."
He laughs — a frustrated, broken sound. His hands are shaking. He looks almost angry at himself.
"But I'm admitting it now because I can't fucking stop talking—oh my god why can't I stop?"
He finally looks at Chuuya again. There's something in his gaze — something almost like worship. Like he's looking at something he'll never be worthy of.
"I'm sorry, Chuuya."
He looks at Chuuya like he's looking at the sun — too bright, too warm, too much for someone like him.
The silence that followed was absolute.
No one moved. No one breathed. Atsushi's hands were pressed against his mouth. Kunikida's pen had rolled off the table. Yosano's arms were wrapped around herself like she was the only thing keeping her together. Akutagawa's face was blank, but his hands were clenched at his sides — nails digging into his palms hard enough to draw blood. Higuchi looked like she might faint. Koyo's fan had frozen mid-motion. Hirotsu's eye was fixed on Dazai with an expression that wasn't surprise—it was something closer to relief.
Ranpo had his glasses off. He was staring at the table. He had tried to stop this. He had warned Chuuya. And now—
Now there was nothing left to do but watch the fallout.
Mori's expression hadn't changed. His face was still calm. His posture was still perfect. But his eyes—his eyes were sharp. He was filing away every word, every detail, every implication. This was information. Valuable information. And he was going to use it.
And Chuuya—
Chuuya hadn't moved.
Dazai stood in the center of the room, exposed, raw, waiting. The serum was still burning through him, but he wasn't saying anything else. He didn't need to. He'd already said everything.
Outside, somewhere in the building, a door opened and closed. Footsteps echoed in the hallway. The world kept moving.
But in that room, time had stopped.
And nothing would ever be the same again.
Chuuya's brain had stopped functioning somewhere around the words "can't help loving you" and hadn't restarted since. The words hit him and his thoughts just… halt. Like someone pulled a plug.
He didn't speak.
He couldn't. His throat was working like he was trying to force words out, but nothing came. He's standing there with his mouth half-open from his interrupted laugh, and he forgets to close it.
He blinks. Once. Twice. Three times. Like his eyes need to reset. Like if he blinks enough times, Dazai will be smirking and saying "just kidding" and everything will go back to normal.
But Dazai isn't smirking. Dazai is looking at him with an expression Chuuya has never seen before and doesn't have a name for.
He stares at Dazai like he's seeing him for the first time.
Or maybe like he's seeing him clearly for the first time.
"That's—" Chuuya stops. Swallows. Starts again. "That's not—you can't just—"
He stood there for a long moment. Frozen. His hands were shaking. His face was white. His eyes were too bright.
And then—slowly, like someone moving through water—he did something so unnatural, so unlike him, that everyone in the room blinked.
He sat down.
Not dramatically. Not with a crash or a collapse. He just—sat. On the nearest chair. His legs had given out. His body had decided for him. He sat down heavily, his hands gripping the armrests, his eyes still fixed on Dazai.
"You absolute bastard" he said.
His voice was hoarse. Cracked. Barely above a whisper. But it was the only thing he could manage.
Then he looked away.
He looked at the floor. At his hands. At anything that wasn't Dazai.
In his head, seven years' worth of memories rearrange themselves into something he doesn't recognize.
And he didn't say another word.
The silence that followed was different from before. Less frozen. More... waiting. Everyone was watching Chuuya, watching Dazai, watching the space between them that had somehow gotten wider and smaller all at once.
No one knew what to say.
No one moved.
Then,a mechanism clicked.
The door—the sealed, locked, door—slid open.
Ranpo was on his feet immediately. He was at the door in three strides, peering into the hallway, his mind already racing.
"The serum," he said. "Whoever set this up timed it. Dazai was right. The door unlocks when the serum wears off." He looked back at the room. "It's over. We can leave."
The tension in the room shifted. People started moving—gathering things, exchanging looks, preparing to exit. The fragile truce was still intact, barely, but no one wanted to stay in that room a moment longer than necessary.
Dazai hadn't moved.
He was still standing where he had confessed. His hands were still at his sides. His face was still pale. His eyes—
His eyes were on Chuuya.
Chuuya stood up.
He didn't look at Dazai. He didn't look at anyone. He walked toward the door—slowly, deliberately, his shoulders tight, his hands shoved deep in his pockets. His face was blank. Unreadable. He walked past Koyo without acknowledging her. Past Hirotsu. Past Mori.
He walked past Dazai without looking at him.
Dazai's breath caught.
Chuuya's shoulder brushed his as he passed—barely a touch, barely a whisper of contact—and then he was gone. Through the door. Down the hallway. Disappearing into the shadows of the building without a single glance back.
Dazai watched him go.
His face didn't change. His mask was back in place—the serum had worn off, and with it, the vulnerability. But his eyes—
His eyes were hollow.
The organizations separated awkwardly, the way two groups of people who had just witnessed something deeply personal and deeply uncomfortable always separate. There were no handshakes. No polite farewells. Just nods and averted gazes and the quiet shuffling of feet toward different exits.
Mori left first, Koyo at his side. His face was calm, composed, but there was a sharpness in his eyes that suggested he was already thinking about how to use what he had learned. Koyo's fan was moving again, but her expression was distant—her mind was elsewhere, on a red-haired man who had left the room without aknowleging anyone.
Akutagawa followed without a word. His hands were bleeding. He didn't seem to notice. Higuchi hurried after him.
Hirotsu was the last of the Port Mafia to leave. He paused at the door and looked back at Dazai. His weathered face was unreadable, but there was something in his eye—something that looked almost like kindness.
"Seven years is a long time," Hirotsu said quietly. "But it's not too late."
Then he was gone.
The Agency stood in the room for a moment longer, gathering themselves. Kunikida was straightening his notebook. Yosano was packing her medical bag. Atsushi was staring at the door Chuuya had walked through.
And Dazai—
Dazai was looking at the floor.
They walked back to the Agency in silence.
The streets were quiet. The sun was setting. The city was the same as it had always been—noisy, chaotic, indifferent to the fact that Dazai Osamu's entire world had just been turned inside out.
Dazai walked at the back of the group. His hands were in his pockets. His face was blank. His footsteps were automatic—left, right, left, right—carrying him forward without any input from his brain.
His brain was somewhere else. Still in that room.
His brain was still watching Chuuya walk past him without looking back.
Atsushi fell into step beside him.
"Dazai-san," Atsushi said. His voice was tentative. Careful. Like he was approaching something wounded.
Dazai didn't respond.
Atsushi walked beside him for a moment longer, gathering his courage. Then he asked the question that had been burning in his chest since they left the building.
"Dazai-san... did you mean it?"
Dazai's footsteps didn't falter. His face didn't change. But something behind his eyes shifted.
"When you said all those things," Atsushi continued, his voice barely above a whisper. "About Chuuya-san. About loving him. About him making you want to live." He swallowed. "Did you mean it?"
Dazai was quiet for a long moment.
The group had stopped. They were all listening now—Kunikida, Yosano, Kyouka, even Ranpo. Everyone was watching Dazai, waiting for his answer.
The serum was gone. He could lie now. He could deflect. He could make a joke, brush it off, pretend it had all been the drug talking.
Dazai kept walking.
"Yes," he said.
His voice was quiet. Flat. But there was no hesitation. No deflection. No mask.
"Yes, I did."
He didn't look at anyone. He just kept walking.
Atsushi's eyes filled with tears.
No one said anything else.
