The forest was alive in ways Ostina had only begun to understand. Every leaf, every blade of grass, every tiny insect carried a pulse, a rhythm of mana that whispered its presence to those who knew how to listen.
She knelt beside a small stream, dipping her fingers into the cool water, feeling the faint currents of life pulsing through the soil, the roots, the water itself. Each particle was alive, each spark carrying a tiny story.
"Everything has mana,"
she whispered to herself, voice trembling with awe. "Even the smallest leaf, even the tiniest bug… everything."
Her long black hair fell forward as she leaned closer, her teal eyes scanning the subtle glow in the water. She could feel it—the way the forest spoke not in words, but in pulses, in currents, in threads of energy connecting all living things. It was beautiful, but also… complicated.
Not all mana was the same. Some belonged to plants, bright and patient, meant for growth and healing. Some belonged to animals, sharp and quick, meant for movement and instinct. And some, hidden deep in the earth or within the roots of ancient trees, carried knowledge and history, old as the world itself.
Ostina's dark magic hummed faintly in response. It was infinite, versatile, and malleable, yet delicate. Too much, and her body would tire, her small frame weakened instantly. Too little, and she could not shape it to her will. She had to learn the balance—the rhythm of giving and taking, asking and receiving.
She stretched her fingers, letting her magic swirl quietly. The small ring she had shaped yesterday hovered faintly in the air, and she wove tiny threads from it into the nearby moss. Slowly, carefully, the moss began to shimmer, pulsing faintly with life.
The plants responded not because she forced them, but because she asked politely, respecting the current of mana that flowed through them.
"It's… it's like learning a language," she whispered. "And every being speaks it differently."
A rustle behind her drew her attention. A squirrel emerged, cautious but curious, its small body quivering slightly. Ostina held her hands open, palms up.
"Would you… share some of your mana with me?" she asked gently.
The creature blinked, and after a tense moment, the faint pulse of its energy flowed into her palm. It was small, barely enough for a single object, but she felt it transform immediately—absorbed by her dark magic and shaped into a tiny leaf-shaped charm, which glowed faintly in her hand.
Her smile was cautious but proud. This is how it works… not by taking, but by asking.
Ostina continued experimenting. She tried combining different sources: water from the stream, the pulse of the moss, and the squirrel's mana. The result was delicate, almost fragile, but she had made a small floating shard of energy that danced above her palm like a living thing. It responded instantly to her thoughts, shifting shape from leaf to feather to tiny stone as she willed it.
Her chest swelled with excitement.
She was beginning to understand the complexity of mana: some required direct connection, some required consent, some could only be shaped into certain forms without corrupting the flow. Some were sharp and quick, useful for offense. Others were slow and steady, perfect for healing or protection. And some—rare, precious—were versatile, able to be shaped into anything with patience and skill.
"This… this is amazing," she murmured, watching the shard hover. Her small body, once frail and weak, felt energized by the connection.
She could feel the mana of the forest weaving through her, guiding her. Yet she also knew she must be careful. One wrong shape, one misuse of this energy, and it could drain her completely, leaving her helpless and exposed.
She focused, closing her eyes, letting her mind expand. A soft wind rustled the trees, and she reached out with her magic—not forcing, not taking, but blending. The shard responded, stretching tendrils toward the roots of the trees.
They pulsed faintly in return, sending a deeper, richer current of mana into her hand. Ostina gasped, feeling the subtle difference: the forest itself had a hierarchy of energy, and the older, stronger beings carried mana that required careful respect.
"Some mana… needs more," she whispered. "It's not just about asking… it's about knowing what it wants, how it works, and how to shape it without breaking it."
A soft trill drew her attention to a bird perched on a low branch. Its feathers shimmered slightly, and she realized that animal mana was different from plant mana—quicker, sharper, and instinctual.
If she tried to use it like plant mana, she would fail. She held out her hand carefully, letting the bird decide. After a moment, it chirped, and a pulse of energy flowed into her. She absorbed it, shaping it into a small glowing feather that darted through the air like a living spark.
Ostina's mind raced with possibilities. This… this is how I can survive… how I can protect myself… how I can grow stronger. She realized that her dark magic was infinite and adaptable, but it could only flourish when she respected the rules of the world—the flow of mana, the will of living beings, and her own physical limits.
Hours passed without her noticing. The sun climbed higher, and the forest hummed softly around her. Ostina had created multiple small objects—feathers, leaves, tiny stones—all pulsing with her magic. Some hovered, some floated, some rested in her hand, but all responded instantly to her thoughts. She had begun to understand how versatile her power truly was.
Yet even in this quiet mastery, questions lingered. Why me? Why was I hidden here? What am I really? She remembered the reflection in the puddle—the long black hair, the teal eyes—and the whispers of the forest seemed to respond faintly, as if acknowledging her heritage. She was more than just a frail orphan; she was something ancient, something powerful, but she still didn't fully understand it.
A shadow shifted behind a thick oak, catching the corner of her eye. Ostina froze, her body tensing. She wasn't afraid—her powers were growing—but she instinctively sensed curiosity and caution. The forest had taught her patience, observation, and care. One wrong move, and she could lose this fragile trust she had built.
Her eyes softened as she turned back to her floating shards of magic. I have so much to learn… so many rules, so many currents to understand. But beneath the uncertainty, a spark of determination glimmered in her teal eyes.
She would learn. She would master this. She would survive—and one day, the world would know that the Trash Saint had been hiding a power beyond imagination all along.
And with that thought, Ostina stretched her small fingers and let the shards of dark magic dance around her, weaving, shaping, pulsing, alive with potential. The forest seemed to hum in approval, the mana threads wrapping around her like a protective veil.
She was no longer just a weak, frail child. She was Ostina, the Demon Lord's secret daughter, learning the language of the world itself—one pulse, one shard, one whispered current of mana at a time.
