What If Tanjiro Found Another Demon Like Nezuko

A demon on Mount Fujikasane spent years starving herself rather than eating people, until Tanjiro and Zenitsu found her during Final Selection. Kiku, a girl turned demon decades earlier, had hidden under a cedar tree through countless selections, refusing to hunt the candidates who passed by. When Zenitsu stumbled into her hollow, she nearly attacked him before stopping herself. Tanjiro arrived and discovered she carried no scent of human prey—she had never eaten anyone. The two boys chose to protect her through the seven-day trial, learning she had been a ferryman's daughter who still clutched the coin her brother gave her. On the final morning, as the sun rose, Kiku asked to see the light one last time and turned to ash holding their hands, leaving only the old coin behind. Tanjiro brought her story and the coin to the Ubuyashiki children, who promised the master of the Demon Slayer Corps would know her name.
