The episode features the wild debut of Inosuke Hashibira , a swordsman wearing a boar mask who bursts through the walls, attacking anything in his path.

The rhythmic thumping of the drums serves as the episode's "heartbeat," building tension before every shift in the environment. If you'd like to dive deeper, let me know: Should I expand on Kyogai’s backstory ?

Every time Kyogai strikes a drum, the room rotates or changes entirely, separating Tanjiro from his companions.
