Death for Luna was nothing like the drama of movies; there was no white light at the end of a tunnel, nor an angel to take her hand. There was only the biting cold of the asphalt and the metallic taste of blood in her mouth. Luna, an eighteen-year-old girl whose breathtaking beauty had always been a burden, stared at the dark sky in her final moments. She, who had spent her entire life governed by cold logic and sharp intelligence, had only one thought at the very end: Rimuru. To her, Rimuru Tempest was more than a fictional character; he was the symbol of order rising from chaos, a power that demanded no flattery.
With a bloodied smile, she whispered, "Voice of the World... it seems you truly don't exist, do you?" With this blasphemy against the laws of existence, she closed her eyes. But the absolute darkness did not last.
When Luna opened her eyes, she was neither in Heaven nor Hell. She had awakened in a new body within the world of High School DxD. The mirror revealed a girl whose beauty now transcended human limits—marble-like skin and eyes that seemed to hold imprisoned stars. But Luna was no fool. She knew this world, despite its outward appearance, was a festering place. She knew that behind the smiles of Rias Gremory and Sona Sitri lay a world of demonic racial discrimination, horrific experiments on innocent humans to extract Sacred Gears, and the filthy political games of gods. In this world, beauty without power was merely an invitation to slavery.
Simultaneously with her awakening, a mechanical voice echoed in her mind: [Gacha System activated. Daily draw is available.] At first, Luna thought this was her key to dominion, but the truth soon struck her like a sledgehammer. This system was absolute trash.
One month remained before the start of the school year at Kuoh Academy—the zero point of the main story. Every day, Luna activated the system with hopes of attaining absolute power, but the results were laughable and humiliating. Day one: an empty plastic bottle. Day seven: a single torn sock. Day fifteen: a rotten banana that filled the room with a stench of decay. Day twenty-nine: a scrap of paper that read "Try again." Sitting on the edge of her bed, Luna stared at the Kuoh skyline. She felt as though the system was mocking her. She knew that if she entered the school in this state, she would be nothing more than a pawn in the demons' chess game. She didn't want to be anyone's "Devil," nor did she want to fight for the false peace of the Angels. She was looking for Him.
The thirtieth day arrived. The final deadline before the storm. Without a shred of hope, Luna opened the transparent system menu. She slammed her finger on the "Summon" option with pure disdain. "Go on... add another piece of garbage to my collection," she muttered. But this time, the gears of the system did not turn. Instead, the entire room fell into an absolute, chilling silence. The voice that emerged from her mind was no longer mechanical; it was a voice that seemed to come from the depths of an eternal void.
[System Error... Intrusion of an undefined entity... Accessing 'Null' source... Summoning initiated.]
Suddenly, the ceiling of the room seemed to rupture, and a dark, infinite expanse—the True Imaginary Space—manifested. The pressure exerted on the room pulverized every piece of furniture. Luna fell to her knees, not out of fear, but from the crushing weight of the presence taking shape.
Out of the stardust and absolute darkness, a woman stepped forth who rewrote the very definition of "Beauty" in Luna's mind. She was tall and dazzling, standing at an imposing 205 centimeters, her shadow engulfing the entire room. Her hair was a deep azure, like the depths of the ocean at night, dancing down to her waist. Upon her head glowed two golden horns etched with ancient runes, signifying a divinity far beyond comprehension.
Her skin was so pale and flawless it seemed woven from pure light. Her eyes... Luna saw the collapse of galaxies within those golden orbs that glowed like molten gold. Her physique was a masterpiece of elegance and absolute power; a towering height paired with a slender waist and a celestial, voluminous bust. She wore a garment that seemed crafted from the very fabric of space-time.
Luna's breath hitched. Her heart hammered against her ribs. She recognized this face. This vibration of the soul, this majesty that made all the Devils and Angels of this world seem like ants, belonged to only one person. "Ri... Rimuru-sama?" Luna whispered in a trembling voice.
The woman fixed her gaze on Luna. A faint, mysterious smile played on her lips. This was Rimuru, but not the kind slime of the Jura Tempest Federation; this was the version Luna had always worshipped in the depths of her heart: an Outer God. A being that had escaped the boundaries of stories and now walked upon this filthy, small world of DxD to redefine everything.
In a voice that was simultaneously a soothing lullaby and a thunderous roar, Rimuru spoke: "So, it was you who called me to this wretched world? Hmm... a fascinating scent of corruption wafts from this planet."
In that moment, Luna realized she no longer needed a trash system. She now stood beside a being who could turn the entire false "Order" of the Three Factions into Null with a single gesture. The true chaos had only just begun.
