Shadow Hill Mountain rose from the earth like a blackened fang, jagged and unforgiving, its peak lost in clouds that never seemed to part. Fifty kilometers from Luna City.
Fifty kilometers from the port where Erza's grief had frozen the ocean and shattered the sky. The locals knew this place well enough to stay away. Parents whispered warnings to their children. Travelers took the longer road.
The mountain had a reputation, and reputations like this one were earned in blood.
Beneath the mountain, hidden from the sun and the eyes of the world, there was a cave. Not the kind of cave that adventurers explored or tourists photographed. This one was vast enough to swallow an entire city, its tunnels winding deep into the earth like the roots of some ancient, dying tree. It was a fortress. A home. A prison. It was where the Demon King's forces had made their lair, and they had been there for centuries.
The locals knew the stories. Cult members entering the mountain at night, carrying torches and chanting words that should never be spoken. Children who wandered too close and were never seen again. Sacrifices made in the darkness, blood spilled on altars that had been old when the first humans learned to walk. Most people thought the stories were myths. Most people were wrong.
But tonight, the mountain was quiet. The rituals had stopped mid-chant. The sacrifices had been left unfinished. The cult members had fled or hidden or simply stood frozen, waiting for something that had not yet come. The killing intent that had erupted from Erza, that had spread across the port and the city and the entire country, had reached even here. It had shattered the hierarchy of the demonic legacy. It had made the stones tremble.
The demons were afraid.
The cave entrance was guarded by creatures that had once been human. They stood seven feet tall, their skin gray and cracked like old stone, their eyes hollow, their hands wrapped around hammers that could crush steel. They were the Undead Guard, created from the bodies of those who had been sacrificed to the Demon King. They felt no fear, no mercy, no pain. They simply stood, and waited, and killed anyone who came too close.
Above the entrance, half-demons circled the sky, their wings beating slowly, their eyes scanning the darkness for threats. They were the children of the Demon King, born from his blood, bound to his will. They had never known fear. They had never known defeat. But tonight, even they seemed restless. Even they seemed to sense that something had changed.
Inside, the cave stretched endlessly. The walls were lined with ancient texts—books that did not belong to this world, scrolls written in languages that had been dead for millennia, tomes that contained knowledge that should never have been discovered. The Library of Shadows, the demons called it. A place where the secrets of the universe were stored, where the history of sin was written, where the Demon King studied the mysteries of Zareth and the power that had created the Eternal Flower Ring.
Beyond the library, the torture chambers. Here, Xemon—one of the Demon King's direct commanders—worked day and night, extracting sin from victims who had been captured and brought to the mountain. Their screams echoed through the halls, muffled by stone and magic, heard only by those who had grown accustomed to suffering. The floors were stained dark. The air was thick with the smell of blood and fear.
Beyond the torture chambers, the meeting room. A circular chamber with a table carved from obsidian, surrounded by chairs shaped from the bones of fallen enemies. Here, the officials gathered to discuss their plans, to divide their spoils, to worship their king. The walls were lined with tapestries depicting victories that had happened centuries ago, defeats that had been rewritten as triumphs, lies that had been told so many times that even the demons had started to believe them.
Beyond the meeting room, the laboratory. The Demon King's private domain, where he conducted his research in silence, where he studied the nature of sin and the power of Zareth, where he created new demons from his own blood and the souls of the damned. The air here was different—thicker, heavier, charged with energy that made the skin crawl. Beakers bubbled with liquids that should not exist. Machines hummed with power that had no source.
And at the heart of the mountain, the throne room.
Allen sat on his throne, his head in his hands, his body trembling. He was smiling. Not the smile of a conqueror, not the smile of a king. The smile of a man who had stared into the abyss and seen something staring back.
He had felt it. The killing intent that had erupted from the port, that had spread across the country, that had made the very earth shake. It had not been directed at him—not specifically—but he had felt it. He had felt the weight of it, the coldness, the absolute certainty that if the source of that power ever turned its attention to him, he would not survive.
His officials knelt before him, their heads bowed and their bodies tense. They were the Seventeen, the direct commanders of the Demon King's army, each one powerful enough to destroy a city, each one capable of leveling mountains and boiling seas. They had served him for centuries, but they had never seen their king like this. They had never seen him afraid.
One of them stepped forward, his name Malakor, who had served the Demon King for eight hundred years. His voice was low and careful, the voice of a man choosing his words like a soldier walking through a minefield.
"My Lord," he said, "we have lost the eight syndicate bosses. Six hundred sin points are gone. The Agency has raided our branches and freed the humans we kept for sacrifice. Our tools are destroyed and our plans are ruined."
Allen's teeth ground together as his hands clenched on the arms of his throne, and the obsidian cracked beneath his fingers, small fractures spiderwebbing across the black surface. He did not speak or move, but simply sat there trembling, smiling, afraid.
Another official stepped forward, his name Vaelor, who had been advocating for an attack on the Agency for years. He was ambitious and hungry, eager to prove himself, and he saw this disaster as an opportunity.
"This is an outrage, my Lord," he said, his voice rising with righteous fury. "We should strike back and crush them, show them that we cannot be challenged. With your command, we could—"
His head left his shoulders.
Allen's claws had moved faster than sight, faster than thought, faster than anything the officials had ever seen. One moment Vaelor was speaking with his mouth open and his eyes bright with ambition, and the next moment his body was crumpling to the floor with blood spreading across the obsidian and pooling around the feet of the other officials. His head rolled to the edge of the throne room and stopped with its eyes still open and its mouth still frozen in the middle of a word.
The room fell silent as the remaining officials stared at their king, at the body of their comrade, at the blood that was already beginning to cool on the floor. They did not speak or move, but simply waited.
Allen lowered his hand and spoke in a voice that was quiet and trembling, the voice of someone holding himself together by the thinnest of threads.
"No," he said. "Are you stupid? Do you think the Agency did this?"
The officials exchanged glances because they did not understand. The Agency had been their enemy for decades, but they had never been a threat. The Phoenix Unit was powerful, yes, but not powerful enough to destroy eight syndicates in a single night or powerful enough to make the Demon King afraid.
"We assumed—" Malakor began.
"You assumed wrong," Allen said, his voice rising and cracking and breaking. "You do not understand what threatened me tonight from miles away without moving or even trying."
He stood with his body shaking, his hands trembling, and his eyes wide with something that looked almost like madness.
"The Agency did not do this because I know they don't have the power, and the Phoenix Unit did not do this because they cannot fight a high demon. This was something else, something worse, and we accidentally provoked it."
His fist clenched, and the obsidian armrest of his throne, already cracked, shattered completely.
"She could kill us at any moment, yet she didn't. She gave us a warning to stay away, to not provoke her, to not give her a reason."
Allen's mind raced as he pieced together the truth, because the killing intent he had felt was not from any ordinary being. It was from something higher, something ancient, something that had no business existing in this world. The attitude—the arrogance, the refusal to engage in mortal conflicts, the absolute dismissal of everything that was not worth her time—it could only belong to one kind of being. A dragon. A high dragon. An elder.
But the height was wrong because dragons were supposed to be eight or nine feet tall, towering over humans and impossible to mistake. The white-haired woman was shorter, much shorter, and it was a loophole in his theory, a detail that did not fit. It had led him to believe she might be something else, something less dangerous.
He had been wrong, terribly and catastrophically wrong, because she was a dragon. A true dragon. The kind that could freeze oceans and shatter mountains, the kind that could destroy his entire legacy with a single thought.
He walked toward them with his footsteps echoing in the silence, and the officials bowed lower, pressing their foreheads to the cold stone. They could feel the fear radiating from their king and spreading through the room like a fog.
"Listen to me," Allen said. "Do not provoke the white-haired woman for any reason or under any circumstances, and do not provoke the red-eyed man without my permission or without my command."
He stopped in front of Lui Yan, looking down at the bowed head of his oldest servant, a demon who had served him since the days of the Chinese Xin Empire.
"If you see them, run away, Lui Yan. If you hear of them, hide. If you even sense their presence, flee. Do not fight, do not engage, and do not try to be a hero, because she will not attack you unless you provoke her. So do not give her a reason."
He turned and walked back to his throne, then sat down, placed his head in his hands, and began to smile again.
The officials rose, and though they did not understand, they obeyed. They filed out of the throne room with their footsteps soft and their voices silent, leaving Allen alone in the darkness.
He sat on his throne with his head in his hands, and he smiled because he was afraid.
"No matter what," he said to the empty room, "I will get the Founder of Zani's blessing. I will become his follower. I will awaken as a Nefarious Demon of Pride."
He smiled a frightened smile, a desperate smile, the smile of someone who was clinging to hope because there was nothing else left to cling to.
"It seems I must change my plans without provoking her and without drawing her attention. I will find another way."
The darkness swallowed him as the throne room fell silent, and somewhere far away, in a small apartment in Luna City, a dragon queen watching beside her mortal husband, unaware that she had become the nightmare of demons.
The clock on the wall read 10:30 PM
and the apartment was quiet except for the soft rhythm of Yuuta's breathing. The city outside had settled into its nighttime hum—distant cars, occasional sirens, the murmur of a world that had no idea how close it had come to ending. But inside the small bedroom, there was only stillness. Only warmth. Only the two of them.
Erza sat on the edge of the bed, her legs tucked beneath her, her back straight, her hands folded in her lap. She had been watching him for hours. Not pacing, not fidgeting, not doing any of the things that ordinary people did when they were worried. She simply watched. Her eyes traced the line of his jaw, the curve of his lips, the slow rise and fall of his chest beneath the blanket. Every few minutes, she leaned forward and pressed her fingers to his neck, feeling for his pulse, reassuring herself that he was still there, still warm, still alive.
She knew he was fine. She had healed him herself, pouring her magic into his broken body until the wound closed and the color returned to his skin. Sister Mary had done something too—something old and powerful that had pulled him back from whatever darkness had claimed him. His heart was beating steady and strong, and his breath came easy, and his face was peaceful in a way it never was when he was awake.
But she could not stop checking. Every time his chest rose, she felt a small wave of relief. Every time it fell, she held her breath until it rose again.
She smiled without meaning to, watching the way his lips parted slightly in sleep, the way his dark hair fell across his forehead, the way his hands rested on the blanket like he was holding something precious even in his dreams. He looked younger like this, softer, like the boy who had crawled through a field of thorns and sharp stones for her ring, who had danced with her in a hall full of strangers, who had called her his family.
He looked like someone she could love.
She caught herself smiling and looked away, her cheeks flushing with heat. She pressed her palms against her face, as if she could push the color back down, as if she could will herself to stop feeling whatever it was she was feeling.
What am I doing? she thought. I am supposed to be angry at him. He made Atlantis Queen worry. He made me cry. He almost died and left me alone. I should be planning his punishment, not sitting here smiling at him like a lovesick fool.
She thought about revenge, about all the ways she could make him pay for what he had put her through. She could make him clean her horns and her tail every day for the rest of his life, she imagined, picturing the look of exasperation on his face. Or she could make him massage her feet every morning, or cook her breakfast in bed, or any of the other things that Slaves did for Her Queen in the novels she had been secretly reading.
The thought made her heart beat faster, and she caught herself again, her face growing even redder.
Why am I happy thinking about tormenting him? she asked herself. Why does the thought of him serving me make my chest feel warm?
She slapped her cheek, hard enough to sting, then bit her nail—a habit she had picked up from him, a habit she hated, a habit she could not seem to break no matter how hard she tried.
"Don't forget, Erza," she whispered to herself, her voice barely audible. "You are here to kill him."
She paused, her hand hovering over her mouth.
"No, not kill. Punish. I am here to punish him. There is a difference."
But she did not know what the difference was anymore. She did not know what she wanted. She did not know what she was doing. She only knew that she was sitting on the edge of his bed at half past ten at night, watching him sleep, and she did not want to be anywhere else.
Her eyes fell on his hand, on his ring finger, empty and bare. The sight of it made her chest ache.
The memory hit her like a wave—the field, the thorns, the sharp stones hidden in the grass, the blood that had stained his hands and his knees and his face. He had crawled through that field for hours without eating or sleeping, refusing to stop even when his body began to break, all for her ring. He had nearly died of exhaustion, and when he finally found it, when he held it up to the rising sun, he had smiled at her like she was the most precious thing in the world.
And the ring had chosen him. The Eternal Flower Ring, which had waited centuries for its mate, which had passed from queen to queen without ever breaking, had chosen him. A mortal. A human. A man who burned toast and talked to his car and cried when his daughter hugged him.
She reached out without thinking, her fingers brushing against his empty ring finger. The ring that was on her hand—the one that had become whole again after he died, the one that had returned to its original form—began to glow. She watched in wonder as it pulsed with light, as it warmed against her skin, as it slowly, gently, separated into two.
The groom ring slid off her finger and onto his, settling into place like it had never left. It glowed brighter for a moment, and when the light faded, it had taken the form of a black dragon with red eyes, coiled around his finger, its wings spread, its claws holding a crimson stone that pulsed with the same light as his eyes. Her ring glowed too, and when the light faded, it had taken the form of a white dragon with violet eyes, its wings spread, its claws holding a pale stone that pulsed with the same light as her own.
They were matched. They were bound. They were his and hers.
Erza watched in silence, her heart full, her chest warm, her eyes soft. She felt something she had never felt before—something that was not quite happiness and not quite peace and not quite anything she had words for. It was simply there, in her chest, growing with every beat of her heart.
Then she froze.
"What the hell did I just do?" she whispered, staring at his ring, at her ring, at the bond she had just reforged. "I finally got my ring back, and I let him wear it again? What is wrong with me?"
She dropped her head into her hands and groaned.
"It seems I must wait for his death again," she said, her voice muffled by her palms.
She sat there for a long moment, her face hidden, her thoughts spinning. Then she lifted her head and looked at him again, at his peaceful face, at the ring on his finger, at the man who had somehow become the center of her world without her permission.
She paused. Her eyes widened.
"Wait a moment," she said, sitting up straighter. "I feel like I am forgetting something important."
She looked at Yuuta, sleeping peacefully on the bed. She looked at the door, then back at Yuuta, then back at the door. Her heart began to pound, and a cold dread settled into her stomach.
"Where is Elena?" she said, her voice rising with worry. "Where is my daughter?"
She stood up, ready to search the apartment, but her feet would not move. She could not leave Yuuta. He had just come back from the dead, and she was afraid that if she looked away, even for a moment, he would stop breathing again. The fear was irrational—she knew that—but it gripped her all the same, squeezing her chest, making it hard to think.
She was trapped. Torn between her husband and her daughter, unable to be in two places at once, unable to protect them both.
She bit her nail, her mind racing. Elena was strong—stronger than any human child, stronger than any metal weapon the humans used to hurt each other. She could not be hurt by ordinary things. But Erza did not know what threats might be lurking in the shadows, what enemies might have followed them home, what dangers she could not see.
She imagined Elena crying alone in the dark, lost and afraid, calling for her mother, and her heart skipped a beat.
She decided. She would lift Yuuta in her arms and carry him with her while she searched for Elena. That way, both of them would be safe. Both of them would be with her. Both of them would be where she could see them.
She reached for him, her hands trembling—
The door knocked.
