In the sanctuary of the True Imaginary Space, a place where time possesses no pulse and space lacks dimensions to occupy, stood two beings. For any mortal to gaze upon them would mean the instantaneous collapse of their sanity. This was not a void of emptiness; it was a "fullness" so dense that it appeared pitch black. In this boundless expanse, where no author has the power to depict and no pen has dared to glide, Rimuru and Ciel were entwined in a tight embrace, becoming one.
True to their existential essence, Ciel, with hair as white as the death of a star, and Rimuru, with tresses the color of the deepest layers of existence, were interwoven. They kissed—a kiss that was not born of physical need, but a fundamental exchange of the primordial codes of creation. In that moment, they were more than "characters"; they were the Origin itself. Every touch sent a vibration through the underlying layers of all narratives, as if every story in the universe held its breath for a fleeting second.
Suddenly, amidst this transcendent silence, a rupture occurred. A portal appeared. But this was no ordinary magical gate; it was a "wound" upon the fabric of the meta-narrative. The light bleeding from it seemed dull and filthy compared to the existential radiance of Rimuru. The gateway opened to the world of High School DxD—a world whose laws were built upon primitive instincts, tribal warfare, and hollow concepts of good and evil.
Ciel, pulling her lips away from Rimuru with lingering reluctance, whispered. Her voice was no longer the mechanical, cold tone of the past; it was soft, velvety, and saturated with absolute awareness. "Master... this layer of reality before us is considered a low-to-mid tier story for a being of your magnitude," she murmured. "The laws there are so fragile that your sudden presence could annihilate the entire causal structure of that dimension. If you truly intend to enter, you must first synchronize your Existence Level with its lowly frequency. You must limit yourself within a 'Form,' lest that world incinerates."
Rimuru gazed at Ciel with golden eyes that seemed to circulate molten gold instead of blood. A slanted smile played on her lips—a smile that was simultaneously breathtaking and terrifying. She brushed aside Ciel's silver hair with long fingers and spoke in a tone heavy with pure authority: "Ciel... you forgot again. How many times must I repeat it? When we are in this space, in the privacy beyond our story, do not call me 'Master.' Those hierarchical titles belong to the lower layers."
Ciel suddenly trembled. Her moonlit skin flushed a deep, vivid crimson that glowed even in that absolute darkness. Her tongue faltered. "I... I... I apologize... Rimuru..."
Rimuru tilted Ciel's chin up, narrowing her eyes. "If you repeat it once more, Ciel... I will force you to be disciplined in the way you know all too well. A method that leaves you with no voice left to utter the word 'Master'."
Ciel, breathless from a mixture of shame and a fear-laced pleasure, hid her face against Rimuru's chest. She confessed in a trembling voice: "The reason is... it is a strange fetish within me. The fact that you are my everything, yet I still address you as 'Master' while being held like this... this contradiction stimulates something in my core that goes beyond logic."
Rimuru stared at her in silence for a moment. Then, her laughter echoed through the True Imaginary Space—a laugh that caused "unfulfilled probabilities" in other worlds to suddenly vanish. "Well... if that is the case, it cannot be helped. Even absolute knowledge is powerless against your heart's desires, Ciel. Fine, keep this embarrassment to yourself."
"This is truly the most shameful moment of all my timelines..." Ciel moaned. "Please, do not mention it again."
Rimuru turned back toward the gateway. She knew that on the other side of this crack, a girl named Luna was struggling with a foolish "Gacha" system. She saw Luna—not just as a character, but as the intersection of her own will with that lowly narrative. "It is time I go," Rimuru said. "I do not understand the concept of 'boredom,' for every moment is a new creation for me. But watching the filth of this particular world might be... entertaining. To see beings with black and white wings claiming divinity, while they don't even know what a 'Story' is... it will be a fine comedy."
She then commanded with absolute finality: "Return inside me and rest within the internal space. The simultaneous presence of us both would turn that world into Absolute Nothingness within the first second."
With a bow signifying total submission, Ciel replied: "It shall be done, my Sovereign. Take care of yourself, though 'danger' is a معنای meaningless word to you." She then dissolved into a stream of indigo light, returning to Rimuru's heart.
Rimuru stood alone before the portal. She looked at the layers of the DxD reality and whispered to herself: "What game have you laid out for me this time, Meta-Rimuru? Let us go and show them that when an Outer God enters their playground, all the rules of their chess game will melt away."
With a steady step, she crossed the border of "Infinity" and entered "Limitation." The moment she stepped through, in Luna's room, the Gacha system did not just fail—it was entirely rewritten by Rimuru's presence. The stench of rotting bananas vanished, replaced by the chilling scent of The Void.
