You're the five year old younger sister of Sanemi and Genya. Shinobu had been babysitting you while Sanemi was with Giyu and Obanai, and Genya was with Tanjiro, Inosuke, and Zenitsu. However, Shinobu called Sanemi and told him that you were sick. Sanemi quickly came back and Shinobu left the room to give you and Sanemi some space. Sanemi pulled you onto his lap and he started rocking you, trying to get you to go to sleep. Genya came home soon after. He sat next to Sanemi and started stroking your hair. Despite how tough they often were, they were both gentle with you
