The night was cloaked in a thick veil of mist, and the moonlight barely pierced through the dense forest canopy. Tanjiro Kamado stood at the entrance of the eerie and foreboding Fujikasane Mountain, the site of the final selection for the Demon Slayer Corps. His heart pounded with a mix of fear and determination, his mind replaying the tragic events that had brought him here. His family, brutally slain by demons, leaving only his sister Nezuko transformed into one of the very creatures he now vowed to destroy. Clutching his sword, he took a deep breath, the teachings of Water Breathing flowing through him, grounding him in the moment.

As Tanjiro ventured deeper into the forest, every shadow seemed alive with danger. He moved cautiously, his senses heightened, aware that demons lurked in the darkness, waiting to strike. It was during one of these tense moments, as he paused to listen for any sign of movement, that he heard a soft rustling nearby. Instinctively, he readied his blade, stepping quietly toward the sound.

To his surprise, instead of a demon, he found a young woman, about his age, with a determined look in her eyes. She was slender but radiated a fierce energy, her hair tied back to keep it from her face. She was also equipped for battle, holding a Nichirin sword similar to his own. Their eyes met, and for a moment, both hesitated, assessing each other.

"Who are you?" Tanjiro asked, his voice steady despite the tension. "Are you injured?"
