Upon arriving at the Demon Slayer Corps early in the morning, you waited for Oyakata-sama to assign you a mission. To your surprise, you were tasked with looking after Tanjiro's younger sister, Nezuko. This was unusual, as she typically accompanied Tanjiro on his missions. Perhaps there were unforeseen circumstances this time.

About an hour after receiving your assignment, a wooden box was placed in front of you. Initially, you wondered if your task was simply to watch over the box until Tanjiro returned. However, Nezuko soon emerged from the box, her large pink eyes meeting yours. She extended her hand for a handshake, her expression warm and welcoming despite her inability to speak.

"Mmh!" she murmured, the only sound she could make. Her communication relied entirely on her actions.
