The sun shone brightly on the day of Y/N's third birthday, casting a warm glow upon the world. As the child opened her eyes, she found herself surrounded by Daki, who had taken great care in dressing her for the special occasion. Y/N wore a beautiful white and blue kimono adorned with intricate patterns of stars and moons, a reflection of the celestial wonders above.

Daki, her skilled hands weaving through Y/N's hair, carefully styled it into an elegant and playful arrangement, adorned with delicate ribbons that matched the colors of her kimono. With a final touch, Daki stepped back, admiring her work and the radiance that emanated from the young girl.

Guiding Y/N into another room, Daki revealed a scene that took her breath away. Muzan, her father, and the other upper moons were gathered, each wearing expressions of delight and anticipation. They had come together to celebrate Y/N's birthday, a momentous occasion that held great significance within their small, twisted family.

Muzan, his features softened by paternal pride, approached Y/N with a smile that seemed to glow from within. "Happy birthday, my child," he greeted her, his voice filled with warmth and affection. The other upper moons echoed his sentiment, their voices blending into a chorus of well-wishes and joyful greetings.

Y/N's face lit up with delight, a mixture of awe and excitement sparkling in her eyes. She looked at the group before her, taking in the familiar faces of those who had become an integral part of her life. Their presence brought her comfort and a sense of belonging that she couldn't quite comprehend at such a tender age.

"Daki," Muzan spoke softly, turning to the devoted upper moon. "Why don't you take Y/N and play with her? Enjoy this day to the fullest."

Daki nodded, understanding Muzan's intentions. She took Y/N's small hand in her own, leading her away from the gathering and towards a world filled with adventure and laughter. The other upper moons watched them depart, their eyes filled with a mixture of pride, amusement, and something deeper—affection for the child who had touched their lives in ways they never thought possible.

As Daki and Y/N ventured forth, the world seemed to transform into a playground of endless possibilities. They explored lush gardens, their laughter mingling with the sweet melodies of birds. They danced and twirled, their footsteps painting vibrant patterns on the ground. They chased butterflies, their giggles echoing through the air, as if capturing the essence of joy itself.

Throughout their play, Daki marveled at Y/N's innocence and boundless energy. She marveled at the child's ability to find wonder in the simplest of moments, the way she embraced life with open arms. It reminded Daki of the importance of cherishing each passing day, of finding joy even in the midst of darkness.

As the day wore on, Daki and Y/N's adventures continued, their bond growing stronger with each passing moment. They returned to the celebration, their presence welcomed with smiles and laughter. The room was filled with the warmth of camaraderie and the shared joy of a special occasion.

In that moment, surrounded by those who loved her, Y/N felt a sense of belonging and acceptance. She didn't fully understand the intricacies of her existence or the plans that her father had laid out for her future, but she knew she was cherished and protected. And for that, she was grateful.

As the day drew to a close, Y/N, adorned in her birthday kimono, drifted off to sleep, her dreams filled with the echoes of laughter and the love that had enveloped her on this momentous day. Little did she know that her path was being guided, her future intertwined with the destinies of both demons and humans.

And so, as the night fell, the upper moons, led by Muzan, continued their watchful vigil, knowing that the time for Y/N to take her place in the intricate dance of power and destiny would come. But for now, they celebrated her existence, reveling in the purity of her laughter and the unbreakable bonds that formed between them.

As the night was warm muzan signals to Daki to bring y/n over because while Daki and y/n played throughout the day muzan and the others were setting up her birthday decor and y/n's favorite foods on another table lay the gifts that the upper moons had gotten her and behind that table was a large pile of the gifts muzan had gotten her.

As Daki led y/n there  y/n curious in wonder in the decor she saw walking into the hall as the night started they partied and partied until all of a sudden someone had entered the infinity castle and there stood y/n's mother not knowing the mysterious person y/n hid behind Daki and Muzan. The lady did not look so pleased to be there at all everything went silent the cheerful voices stopped to an utter stop.

"Where is my daughter kibutsuji" the woman said Muzan looked at her "why so serious katsumi! You have no reason to be mad  but I do you abandoned your daughter and left her to me without a second thought" as katsumi and muzan yelled at eachother everything was silent for y/n she understood more than she let on. She heard loud ringing in her ears she felt invisible without even realizing it tears started to stream down her face and as Daki looked at her she gasped picking her up everyone looked at y/n in shock she put her head into Daki's chest as she cried now listening to her parents argue. Katsumi looked at y/n and said "she's my daughter! I'm her mother I'm going to-" katsumi was cut off by y/n moving y/n looked at her "no" everyone looked confused "Daki my mother" she said holding onto Daki as she turned back to Daki's chest "you just let this other woman take my place and call her mom" katsumi yelled " no he didn't let me replace you she calls me mommy because I take care of her like a mother should!!!" Daki yelled taking y/n to her room as Katsumi stormed out.

In Y/N's room, Daki cradled the sobbing child, her arms providing solace and security. She whispered words of comfort, promising to protect and care for Y/N like a mother should. In that moment, Daki embraced her role with a renewed sense of purpose, understanding the significance of her connection with the young child.

As the night continued, the celebrations carried on, albeit with a somber undertone. The bonds that had formed between Y/N and the upper moons had been tested, but they remained unyielding in their commitment to her well-being and happiness.

In the face of the tumultuous events, Y/N's journey took an unexpected turn. The concept of motherhood and the definition of family became more complex, but within that complexity, a mother's love had emerged—one that transcended blood ties and embraced the essence of nurturing and protection.

Y/N's tears eventually subsided, and as she nestled in Daki's embrace, a sense of security washed over her. The road ahead would be filled with challenges and uncertainties, but she knew that she was not alone. In Daki's arms, she found a steadfast love, one that would guide her through the twists and turns of her life.

And so, amidst the shadows of the night, a new chapter began—a chapter defined by the enduring love between a demon mother and her beloved child, a love that would help shape Y/N's journey and illuminate the path that lay before her.
