Chapter 13

You are... (おが) is the thirteenth chapter of Koyoharu Gotōge's Kimetsu no Yaiba.

Summary
The chapter begins with the Swamp Demon having a flashback regarding an encounter with Muzan, the memory occurs at the instant when the Swamp Demon transformed from his human form and is seen being held up in the air by the neck. Muzan apparently warns the demon to never speak or disclose any information regarding him, insinuating that he would always be watching.

The flashback ends and the chapter resumes with the Swamp Demon trembling in fear at Tanjirou's request for more information regarding Muzan. The Swamp Demon persistently refuses and attempts to regenerate in order to attack Tanjirou but is quickly killed before he gets the chance to do so.

Tanjirou returns to a sleeping Nezuko and apologizes to her once again for failing to gather intel on how to revert her back to her human form. He sees Kazumi on the floor with a distraught look on his face and checks to see if he's alright.
