S1E12 The Boar Bares Its Fangs, Zenitsu Sleeps

Inside the house, where the rooms shift with the sound of the tsuzumi, Tanjiro finds himself separated from Zenitsu Agatsuma. Alone, Zenitsu is engulfed by fear and hopelessness as he guides Shoichi through the disorienting space. At the same time, Tanjiro encounters the house's master, a demon playing the tsuzumi, along with a peculiar man donning a boar's head mask.
