Work Text:

The night was heavy, suffocating, as if the air itself was made of ashes. Silence filled the improvised prison of the League, broken only by the dragging sound of Shigaraki’s footsteps. His fingers twitched restlessly, brushing against the cold walls, leaving faint marks of disintegration. He couldn’t stand the emptiness. He couldn’t stand the taste of defeat that still burned in his mind.

Shigaraki thought about everything he had lost. The League’s trust, the respect of villains, the weight of being All For One’s successor. And above all, he thought about loneliness. He had always believed chaos would be enough to fill the void inside him, but now, alone, he realized chaos without witness had no meaning.

Then a blue flame cut through the darkness. Fire lit the corridor like an invitation to hell. Dabi was there, emerging from the shadows with that crooked smile, as if he had been waiting for the perfect moment to appear.

“You really thought I’d leave you here?” Dabi said, his voice rough, laced with irony and something more—an obsession burning alongside his flames.

Shigaraki lifted his gaze, surprised but trying to hide it. “Then why? You could’ve let it all rot.”

Dabi stepped closer, the fire reflecting in his eyes. “Because without you, none of this makes sense. I want to watch the world burn, but only if you’re by my side.”

The silence between them was heavy, but not empty. Every word was a spark, igniting something they both tried to bury. Shigaraki felt his heart race—not from fear, but from recognizing in that voice something he would never admit: need.

He laughed, low and distorted. “You talk like I matter… but I’m just destruction.”

Dabi tilted his head, moving closer. “That’s exactly why. You destroy, I burn. Together, nothing remains. And I love that. I love you for that.”

Shigaraki said nothing, but his fingers stopped trembling. For the first time, it wasn’t just chaos filling him. It was Dabi.

The city streets were deserted, swallowed by shadows. Shigaraki and Dabi walked side by side, their presence alone enough to poison the silence. Every step felt like a promise of ruin.

“You talk like I’m important,” Shigaraki muttered, his voice low, almost mocking. “But I’m nothing more than destruction.”

Dabi chuckled, the sound rough but strangely intimate. “That’s exactly why I can’t let you go. You destroy, I burn. Together, we erase everything. And I crave that. I crave you.”

Shigaraki turned his head slightly, his red eyes narrowing. “Crave me?”

“Obsession,” Dabi whispered, his flames flickering as if echoing his words. “Love is obsession. Love is not being able to breathe without thinking of the other. Love is wanting to watch the world collapse, but only if the other is there to see it. You’re my addiction, Shigaraki. My fire doesn’t exist without your dust.”

Shigaraki let out a distorted laugh, but there was no mockery in it—only recognition. “Then we’re both sick. I don’t just want to destroy the world… I want to destroy it with you.”

Dabi moved closer, his forehead brushing against Shigaraki’s. The blue flames trembled, reflecting the madness in his eyes. “That’s all I needed to hear.”

The night swallowed their words, but the promise lingered: two broken hearts, bound by obsession, ready to turn the world into ashes and laugh at the ruins.

The city was silent, but silence never lasted long when they were together. Shigaraki’s fingers brushed against the walls of an abandoned building, and the concrete began to crumble into dust. Beside him, Dabi’s flames flickered, restless, hungry, waiting for the signal.

“This place,” Shigaraki muttered, his voice low and distorted, “it’s nothing but a carcass. Let’s turn it into ashes.”

Dabi smirked, the fire in his eyes burning brighter than the flames in his hands. “I was waiting for you to say that. You destroy, I burn. Together, we erase everything.”

With a single touch, Shigaraki’s decay spread like a disease, devouring the structure from within. Dabi raised his arm, and a torrent of blue fire roared to life, swallowing the building whole. The explosion of dust and flame lit up the night sky, a twisted symphony of chaos.

Shigaraki turned to him, the reflection of fire dancing in his red eyes. “Every time you burn, I feel alive. You free me from the emptiness.”

Dabi stepped closer, his voice rough but trembling with obsession. “And every time you destroy, I fall deeper. You’re my addiction, Shigaraki. My fire doesn’t exist without your dust.”

The ruins collapsed behind them, but neither looked back. They walked forward, side by side, leaving only destruction in their wake.

“Promise me,” Shigaraki whispered, almost desperate, “promise you won’t leave me.”

Dabi leaned in, his forehead brushing against Shigaraki’s, the flames flickering like a heartbeat. “I don’t leave flames. I don’t leave ashes. And I’ll never leave you.”

The city burned, the world crumbled, and in the middle of it all, they laughed—two broken souls, bound by obsession, turning everything into ashes and burning blue fire.

The city was burning behind them, flames licking the sky, dust swirling like a storm. But neither of them looked back. For Shigaraki and Dabi, the ruins were not an end—they were proof of their bond.

Shigaraki’s voice broke the silence, low and trembling, almost like a confession. “Promise me… promise you won’t leave me. Not when the world turns against us. Not when everything falls apart.”

Dabi stepped closer, the heat of his flames wrapping around them like a twisted embrace. His forehead brushed against Shigaraki’s, his voice rough but steady. “I don’t leave flames. I don’t leave ashes. And I’ll never leave you.”

Shigaraki’s fingers hovered near Dabi’s arm, the urge to destroy fighting against the need to hold. For once, he chose restraint. “You’re the only one who understands. The only one who makes this emptiness bearable.”

Dabi’s smirk softened into something darker, more intimate. “You’re my addiction, Shigaraki. My obsession. Without you, my fire dies. Without me, your dust is meaningless. Together, we’re everything—and nothing.”

The night swallowed their words, but the promise lingered like fire in the air. They were not just villains. They were lovers of chaos, bound by obsession, ready to tear the world apart and laugh at the ruins.

And in that moment, surrounded by destruction, they sealed their vow: to burn, to decay, to destroy—always together.

The city was no longer silent. Sirens screamed in the distance, and the shadows of heroes approached through the smoke. Shigaraki and Dabi stood side by side, their bodies tense but their bond unshaken.

“They’re coming,” Shigaraki muttered, his fingers twitching with anticipation. “The ones who think they can save this rotten world.”

Dabi smirked, flames flickering around his hands. “Let them come. I want them to see what happens when obsession and destruction fight together.”

The first wave of heroes charged, their voices filled with determination. Shigaraki raised his hand, and the ground beneath them began to decay, swallowing their courage in dust. Dabi’s fire roared, blue flames consuming everything in its path. Together, they moved like a storm—chaos and fire, dust and ruin.

“Every time you fight beside me,” Shigaraki whispered between breaths, “I feel invincible.”

Dabi’s laughter echoed through the battlefield, rough and manic. “And every time you destroy, I fall deeper. You’re mine, Shigaraki. My addiction. My obsession. My partner in chaos.”

The heroes faltered, overwhelmed not just by power, but by the twisted unity before them. Shigaraki and Dabi weren’t fighting for victory—they were fighting for each other, for the promise they had made in the ashes.

As the last flames consumed the battlefield, Shigaraki turned to Dabi, his red eyes glowing. “This world will end, and when it does, it will be our masterpiece.”

Dabi leaned closer, his voice low, almost tender despite the destruction. “And we’ll laugh at the ruins together. Always together.”

The city burned, the heroes fell, and in the middle of the chaos, two broken souls stood united—lovers of destruction, bound by obsession, sealing their fate in fire and dust.
