[Scene - Ironwood Kingdom – Eastern Demon Lord's Fortress]
In the far eastern reaches of the continent of Velgrith, where the sun rises over jagged, obsidian peaks, the Eastern Demon Lord's fortress stood like a jagged shard of night piercing the sky. Inside the throne room, the air did not merely sit; it vibrated with a predatory, lethal intent that made the very stones seem to sweat.
The Eastern Demon Lord, Asmodai, sat motionless on a throne carved from the bones of primordial giants.
His eyes, glowing like dying embers in a forge, were fixed on a kneeling scout clad in tattered black robes.
"You still haven't found the boy?" Asmodai's voice was a low, measured rasp, yet it carried the weight of a collapsing mountain.
The scout's head pressed lower against the cold floor.
"We have searched every hamlet and village east of the human capital, Valerion, my lord. We have scoured the Ironwood borders. He is either a ghost, or we were mistaken about the resonance."
"We are not mistaken," Asmodai roared, the sound shattering several nearby crystal ornaments. He drove his claws into the armrest of his throne, leaving deep gouges in the bone.
"The magical resonance that shook the ancient ruins eight years ago was a signature I could never forget. It was identical to the Dark Magic God Umbyas's final breath. That power has returned. It is a seed, and if it is allowed to take root in the heart of Ironwood, it will bloom into our destruction."
He looked toward the window, where a crimson moon began to rise. "He must be there. Hidden in plain sight, masked by the mundane."

[Scene - Year 209 of the Velgrith Union. Forest outside Ironwood human territory - Midnight - Kuro, age 8]
Ten leagues away, deep within the forbidden forests that skirted the Ironwood Kingdom's human territory, the Year 209 was marked by a silence so absolute it felt unnatural.
Kuro Velgrith, only eight years old, sat cross-legged in a clearing where the trees were twisted into agonized shapes. His silver hair shimmered under a pale moon that was slowly being devoured by a rising, violet mist.
To any passing traveler, he would have looked like a lost child, but a closer look at his eyes—deep, void-like purple—revealed a soul that had already lived a lifetime of trauma and manipulation.
Kuro closed his eyes, his mind drifting back to his project life in Tokyo. He remembered his father, Hajime, handing him a black book on psychology at age six. He remembered the moment his heart cracked upon hearing his parents call him a tool.
In this new world, he had been reborn to Darken and Lyra Velgrith, retired A-rank adventurers who offered him warmth, yet Kuro felt nothing but a cool, analytical detachment.
"Justice and kindness are deceptions told by the strong," he thought, his fingers twitching in the rhythm of a silent incantation.
"In my first life, I was a weapon for the Yakuza. In this life, I will be the hand that holds the chessboard."
He had spent weeks studying an ancient, forbidden text he'd found in his parents' attic, deciphering a summoning magic that transcended the six elemental laws of Velgrith. It was a gateway to the Abyss—the source of the Dark Magic God's original power.
"It's time," Kuro whispered.
He raised his left hand. The air around him began to curdle. Dark energy, thick as oil and smelling of ozone and old graves, coiled around his small frame like a serpent.
"Invoke: Abyss Gate."
The ground didn't just shake; it groaned as if the earth itself were being torn asunder. A silent, swirling chasm of absolute blackness manifested in the air. It wasn't a whirlpool of motion, but a static, watching eye of void. The trees in a ten-meter radius withered instantly, their life force sucked into the vacuum of the portal.
Kuro leaned forward, his breathing heavy but his heart rate perfectly rhythmic. He was not a child playing with fire; he was a scientist observing a reaction.
Kuro's consciousness dipped into the chasm. Inside the Abyss, time did not flow; it stagnated. There was no up or down, only a chilling, psychic cold that sought to freeze the spirit.
In the center of this nothingness, he saw her.
A girl, perhaps a year or two older than himself, was suspended in the void. She was bound by magical chains that pulsed with a sickening red and purple light. Her hair was a striking contrast—a chaotic of silver —and her skin was as pale as moonlight.
As Kuro approached her spirit, he felt a jolt of recognition. Her blood wasn't merely demonic. It was ancient—a lineage thought to have been purged during the First Hero's False Peace a century ago.
She was a Nocturne, a high-demon bloodline capable of mimicking human appearance, yet carrying an aura that rivaled the gods.
"Who are you?" Kuro's voice echoed through the psychic medium.
The girl's eyes fluttered open. They were purple—a shade that Kuro found aesthetically pleasing, a rare moment of subjective preference in his logical world. She looked at him, and through the haze of her torture, her lips moved silently.
"Help…"
Kuro stood still, his mind racing through permutations.
"If I save her, I risk the attention of the God who gives me reincarnation. If I leave her, a valuable asset is lost to the void. She is a descendant of the high demons. Her mana is unstable, but her potential is limitless."
He didn't lie to himself. There was no surge of heroism, no burning desire to protect the innocent. He viewed her exactly as Kenzuki Yamato had once viewed him: as a quiet tool.
"She could be useful," Kuro muttered. "Rare blood. Forbidden magic. Her existence is a variable I can control."
Yet, as he reached out, his heartbeat faltered for a millisecond—an unidentifiable flicker of an emotion he thought he had buried in the concrete of Tokyo. He ignored it and thrust his hand toward the chains.
"Release: Shadow Grasp."
Dark talons of mana erupted from Kuro's shadow, latching onto the red-and-purple chains. The runes on the bindings shrieked in a language of agony before shattering into dust.
BOOM!
The feedback of the Abyss Gate closing threw Kuro backward across the clearing. He hit a withered oak with a dull thud, smoke and violet dust filling the air. He coughed, his small body aching, but he forced himself up.
From the fading shadows of the portal, the girl emerged. she collapsed into the dead grass, her breathing shallow but steady.
Kuro carried the girl to a hidden limestone cave at the forest's edge—a sanctuary he had reinforced with Soul Veil magic to hide his practice from his parents.
He laid her on a bed of dry moss and began his diagnosis. He placed a hand on her forehead, and his eyes narrowed.
The mana inside her was a chaotic storm. But more importantly, there were psychic chains embedded in her soul—deep, subtle, and human-made.
"This isn't a demon's curse," Kuro realized, his voice dropping to a cold whisper.
"It's a human sorcery. A control mechanism."
He did not know yet that this girl had been a puppet of a sorcerer working under the Eastern Demon Lord—a sorcerer who had been aided by the machinations of the First Summoned Hero.
The girl believed she had dreams and aspirations, but they were manufactured scripts designed to lead her toward a specific fate.
Now, she was free. Or rather, she was under new management.

[Scene - Demon Empire – Eastern Frontier]
In the heart of the Great Demon Empire, the Great Demon Lord stood rigid atop his obsidian spire. He turned his gaze toward the Ironwood Kingdom.
"He opened an Abyss Gate?" the Great Demon Lord asked.
A shadow-wraith nodded. "For only three seconds, my King. But the echo reached the pillars of the world. The resonance was... divine."
The Great Demon Lord clenched his fist, a dark smile spreading across his face. "It is him. The heir to the darkness. The gods believe they have summoned a Hero of Light to balance the scales, but they are playing a game they've already lost."
His eyes narrowed. "Well... now he has the girl. Let us see if the Darkness Lord can handle the weight of a soul that has been shattered as badly as his own."

[Scene - The Girl Sleeps – Kuro's Observations]
Back in the cave, Kuro sat in the darkness, watching the girl sleep. He didn't know her name yet—Rei. He didn't know that she would eventually become his Nocturne shadow. He only knew that the first piece had been moved on the board.
"The world is built on lies," Kuro said to the silence. "I will become the villain who tells the truth."
