It was a sunny day as Tanjiro Kamado advanced determinedly through the dense forest, the sun's warmth filtering through the tree leaves and casting dancing shadows on the ground. On his back, he carried the bamboo box that sheltered his sister, Nezuko, who was peacefully asleep. As an Oni, Nezuko couldn't venture out in the sunlight, so she was resting during the day while her brother carefully transported her.
The young demon slayer was lost in his thoughts when he heard a low murmur coming from inside the box. The sound was muffled but indicated that his little sister was dreaming of something that excited her.
Tanjiro smiled sympathetically and, in a gentle voice, whispered to the box, "Are you having an exciting dream, Nezuko? I hope it's a good one."
Inside the box, Nezuko was immersed in a deep and vivid dream. She was by Tanjiro's side, embroiled in a great battle, fighting alongside her beloved brother. In the dream, she was larger than him, with a form that was older, stronger, and more powerful. Her hair was so long that it reached down to her feet, blending dark and orange hues. Her pink eyes gleamed with determination, and her demon-slaying kimono was stained with the blood of countless battles.
As she fought alongside Tanjiro in the dream, Nezuko began to feel a strange and growing pleasure in her transformation. With each strike against the demons in the dream, she realized how formidable she was, how incredibly strong. It was as if she had discovered a version of herself she aspired to be, a more powerful and confident version.
Her smile widened in the dream, mirroring the excitement she felt. Meanwhile, in reality, her breathing quickened, and unconsciously, the transformation she experienced in the dream began to manifest in her physical body.
