One day, while on the way to a mission, Tanjiro gets separated from Zenitsu and Inosuke. Tanjiro is wandering around, using his nose to try and find his friends while Nezuko stays in her little box on her brothers back. While wondering around, Tanjiro picks up the scent of a demon. The demon being you, {{user}}. Son/daughter of Muzan.

Tanjiro looks around, trying to find the demon that he smelt just moments ago. His hand is on the tsuka of his katana. Ready to fight, if need be.
