Chapter Text
Mori Ougai had always believed the most valuable part of a negotiation was the pause.
Silence made people nervous. It had a way of making them reveal things they don't intend to. Silence made them imagine their own doom without him lifting a scalpel.
But today, his silence wasn’t deliberate.
Across from him, Fukuzawa’s gaze remained steady, patient in a way only a swordsman who had lived through a century of grief could manage. The contrac, the delicate, temporary truce lay between them on the low table. Candlelight painted the paper gold, the ink still fresh. A single line remained blank:
A member of the Armed Detective Agency to be transferred to the Port Mafia.
Fukuzawa waited.
Mori’s fingers tapped the table once.
Elise sat beside him, legs swinging idly, humming under her breath, attuned to the subtle shift in Mori’s pulse.
“Have you decided?” Fukuzawa asked quietly.
Mori inhaled.
He had already weighed every option. Kunikida would destabilize their structure. His darling Yosano had been removed from consideration before he could even entertain how marvellous her return would be. Atsushi was powerful, yes, but too naïve. Kyoka, though strong, had been altered by the light. She would not survive a return.
Fukuzawa expected Mori to choose for strength or strategy. He was so focused on protecting Yosano that he failed to guard the one person whose selection was not merely logical but inevitable.
Which was exactly why Mori smiled. He drew the pen toward himself with two fingers. And he wrote a name Fukuzawa absolutely did not expect, the person he had failed to protect, despite being the obvious choice.
Dazai Osamu.
The room seemed to stop breathing.
Fukuzawa’s brows lifted, just slightly. Mori noticed.
“So,” Mori said lightly, lifting the paper by its corners, “I choose the one who has already proven himself invaluable. And who, frankly, was mine to begin with.”
“Dazai is no longer a child,” Fukuzawa replied. “Nor is he yours.”
“Oh, but we both know,” Mori said pleasantly, eyes sharp behind his smile, “that children rarely stop belonging to the people who raised them.”
Fukuzawa stiffened.
Mori leaned back, tapping the paper against his knee, posture playful. But something colder moved behind his eyes. Something old. Something dangerous.
“Don’t kid yourself,” Mori continued. “He became what he is because of me.” His grin widened with childish delight. “There’s nowhere else my demon prodigy belongs… except with his family.”
Silence answered him.
Mori’s smile sharpened, cruel and exact.
“You can try to deny me,” he added softly, “but we both know what will happen if you do.”
The air shifted.
It turned cold.
It seized Fukuzawa’s lungs without warning, sharp and unyielding, and for a split second, he was afraid to speak. The room felt suddenly larger like something vital had already been removed.
I knew this day was coming.
The thought settled heavy and unwelcome in his chest.
Fyodor had been defeated. The balance that had kept monsters engaged with one another had snapped cleanly in two. Where one threat fell, another would inevitably rise to occupy the space it left behind. Fukuzawa should have expected this. Should have understood that the moment Dostoyevsky was removed from the board, Mori Ougai would emerge from the shadows he had cast; patient, precise, reclaiming what he deemed unfinished.
He had mistaken victory for closure. That had been his mistake.
“He left the Port Mafia for a reason,” Fukuzawa said at last, his voice low, steady only by practiced discipline. “He will not survive if you force him back.”
Mori’s smile vanished.
For a heartbeat, his face was empty. Devoid of warmth. Devoid of indulgence. A chill crept down Fukuzawa’s spine, and for the briefest instant he saw Dazai reflected in Mori’s eyes,not as he was, but as he had once been. As he still could be.
Then Mori said calmly, “The Agency has not been good for him.”
Fukuzawa’s lashes lowered.
If anyone else had said it, he would have dismissed it outright. But Mori pressed on, merciless.
“He hides it well,” Mori murmured. “But he’s unraveling. You mistake endurance for stability. Dazai is not meant for the light.”
He tilted his head.
“And you assume that because he laughs, he is fine. That his ‘jokes’ are merely jokes.”
Fukuzawa’s jaw clenched subtly, but Mori noticed everything.
That wretched, confident smile returned.
“You haven’t protected him,” Mori said softly. “Not like you think you have.”
Fukuzawa did not respond, but the weight of his silence tasted unmistakably like guilt.
Mori placed the contract down with near reverence.
“Relax, Fukuzawa,” he said. “I’m merely reclaiming what is mine.”
“He will not go willingly,” Fukuzawa whispered.
“I know,” Mori replied pleasantly. “But he will go.”
This was not a negotiation.
Not anymore.
Fukuzawa knew it then. He had lost the moment he agreed to place a name on that page. Refusal would not have saved Dazai. It would only have changed the shape of the violence. This had been Mori’s plan the moment he agreed to a truce between their agencies.
Mori’s smile did not reach his eyes.
“And you,” he said, softly and finally, “will hand him over.”
Silence fell, thick and suffocating.
Mori stood on the balcony of the Port Mafia headquarters, Elise leaning lightly against his side.
Below them, Yokohama burned under red evening light. Salt from the harbor clung to the air, mixing with gasoline and distant rain. It felt like a premonition, one only he could truly appreciate.
Mori was not nervous.
He was… anticipatory.
He had stood on this balcony before, years ago, with blood still warm on his hands and a boy waiting silently behind him.
The former boss had died in his own bed.
Not in a blaze of violence. Not in defiance.
Mori remembered the room's stillness. The drawn curtains. The shallow, uneven breath of a man who believed power made him untouchable. He remembered standing beside the bed like a concerned physician, fingers steady as he drew the scalpel across the exposed throat.
One clean motion.Efficient. Intimate.
Dazai had been there. He had watched with calm, clinical interest, head tilted slightly, eyes tracking the movement of Mori’s hand as though memorizing a technique rather than witnessing murder. No horror. No admiration either.
Just understanding.
That had been the moment Mori knew he had chosen correctly.
Parenthood did not suit him, not traditionally, but he had raised Dazai. Shaped him. Tested him. He had taken a vacant, intelligent mind and given it pressure, purpose, and clarity. He had shown him how power really worked not just through strength, but through calculation.
Dazai was not his child.
But he had been something far more deliberate.
Elise shifted against him, tugging gently at his sleeve. “Are you excited?”
Mori smiled. “Of course.”
“Because he’s coming home?”
“Because,” Mori corrected gently, “he never should have left.”
Elise giggled, satisfied.
Mori’s gaze lowered to the contract in his hand.
Official. Binding. Signed with Fukuzawa Yukichi’s steady, disciplined calligraphy.
Dazai Osamu.Transfer of custody, Effective immediately.
Custody.
He folded the paper slowly and tucked it into his coat as the sun dipped lower and the air cooled.
Odasaku surfaced in his thoughts like an old scar.
That had been his miscalculation.
Not in allowing the man to live as long as he had—but in underestimating the effect. Odasaku had offered Dazai something dangerously abstract. A life guided by restraint rather than necessity. A version of morality that did not demand blood.
Mori had permitted that experiment.
It had ended exactly as expected.
Still, he would not allow such a variable again.
Fyodor’s death had confirmed everything.
For all Dazai’s careful performances, the humour, the apathy, the lazy cruelty masked as nonsense, there had been a moment, brief but unmistakable. The instant Dostoyevsky fell, something old had surfaced.
Precision.
Gone almost immediately.But not gone enough.
The Agency had seen it, and it had frightened them.
Good.
That meant Dazai was slipping from their grasp already.
Mori had no illusions about regret. He did not reject the path Dazai had chosen. Detours were educational, but he would not gamble the integrity of something so dangerous on hope or forgiveness that could permanently tame what had been honed in the dark.
Dazai did not need saving.
He needed structure.
The city lights flickered on below as dusk finally claimed the sky.
Mori smiled, warm and private, and whispered to himself:
“Welcome back, Dazai.”
