Let's Train Heroine

The air was thick with the stench of death as the demon emerged from the shadows, its true form revealed beneath the pale moonlight. Gone was the towering, shadowy figure that had tormented Julia and her team. What stood now was a grotesque creature, a mass of bloated flesh and decay. Its body was round and swollen, covered in oozing pores that leaked acid, which hissed as it dripped onto the ground.

Every step the demon took left a trail of destruction in its wake. Plants withered and died instantly, their vibrant green turning to ash as the acidic liquid touched them.

The demon's single, bulging eye glowed a sickly yellow in the night, its gaze wild with rage and hunger. Its fat limbs hung loosely at its sides, and its grotesque form seemed barely capable of supporting its own weight.

For a moment, the demon stood in silence, surveying the devastation it had wrought. Then, with a growl that reverberated through the trees, it turned its eye toward the figure standing in the clearing ahead of it.

Nyx.

She was a stark contrast to the monstrosity before her. A strikingly beautiful woman, her skin was the color of deep ebony, smooth and flawless. She wore a flowing white dress that clung to her body in a way that accentuated her elegance and grace, though it covered her from neck to toe. The fabric shimmered under the moonlight, the pure white stark against the darkness of the forest.

Her hair was long and dark, cascading down her back in waves, though it seemed to blend into the night itself, as if part of the shadows. But it was her eyes—those cold, unblinking eyes—that drew attention most of all. They were completely white, with no pupils, glowing faintly as they surveyed the world around her with calm indifference.

The demon's eye narrowed as it spotted her, its acid-covered body rippling with tension.

"Who are you?" the demon rasped, its voice a low, guttural growl that shook the ground beneath them. Acid dripped from its mouth as it spoke, sizzling where it landed on the dead earth.

Nyx did not answer immediately. Her white eyes shifted briefly, and she looked past the demon, watching as Julia and Rina fled in the distance, carrying their fallen comrades—Olive's disfigured body in Julia's arms, and Hima's unconscious form slung over Rina's shoulder. For a brief moment, her lips curved into a faint smile, amused by the futility of their efforts.

But they were not her concern.

She shifted her gaze back to the demon, her smile fading as her expression became one of cold calculation. She took a single step forward, her white dress swirling around her feet like mist. The demon recoiled slightly, its massive body trembling as it sensed something far more dangerous in her than it had expected.

Nyx's voice, when she finally spoke, was soft but commanding, carrying an authority that sent a chill through the air. "You will serve me," she said simply, as though it were a fact, not a request.

The demon snarled, its body swelling with anger. "Serve you? I serve no one! I am Z'thraag, the destroyer of worlds! The eater of souls! I will not—"

Nyx tilted her head slightly, and her white eyes gleamed with an unnatural light. She didn't raise her voice, didn't move a muscle, yet there was something in the way she looked at the demon that made it falter. "You will serve me," she repeated, her tone calm and absolute. "It is not up to you."

Z'thraag's defiance wavered. He tried to roar, to lash out in anger, but the moment he looked into her eyes, he felt something shift deep inside him. A cold, gnawing fear unlike anything he had ever experienced gripped his core. Those eyes—those horrible, white eyes—seemed to pierce through his very essence, stripping away his will, his power, everything that made him who he was.

Without understanding why, Z'thraag's massive body trembled, and he found himself falling to his knees. His mind screamed at him to resist, to fight back, but his body refused to obey. His one great eye widened in terror, and his acid-covered skin rippled as fear took hold of him.

Nyx stepped closer, her gaze never leaving the demon's. She didn't smile, didn't gloat. Her expression remained cold, emotionless, as though this moment was nothing more than a formality. "You will destroy the Moon Light Country," she said, her voice smooth and unyielding. "That is your first task as my slave. Once it is done, you will come to my fortress."

Z'thraag's throat tightened as he tried to speak, but no words came out. His entire body was paralyzed with fear, and the crushing weight of Nyx's command left him powerless to resist. He could only bow his head, trembling in submission.

Nyx watched him for a moment longer, then nodded in satisfaction. Without another word, she turned and began to walk away, her white dress trailing behind her like a ghostly shadow. In the blink of an eye, she disappeared into the darkness, leaving the demon alone in the clearing.

Even after she had gone, Z'thraag remained on his knees, unable to move. His mind was still reeling from the encounter, and though she was no longer there, the terror she had instilled in him lingered. For the first time in his existence, Z'thraag—the great destroyer—felt utterly powerless.

And so, he knelt there, too afraid to rise, waiting for the fear to subside.

It never did.

Julia and Rina stumbled into the dimly lit room, their bodies battered and bruised from the brutal fight with the demon. They both bore numerous injuries—cuts, burns, and deep gashes marking their skin like battle-hardened warriors. The acid burns from the demon had seared their flesh, leaving patches of skin red, raw, and scarred.

Rina's left shoulder had been torn open, a jagged wound still fresh and bleeding. Julia's arms and legs were covered in burns, and her face was marred by a long scar running down her cheek.

But neither of them cared about their injuries. They weren't thinking of themselves at all.

All of their concern, all of their worry, was for the two figures lying motionless in the beds before them—Hima and Olive.
