Ep. 4: Tanjiro dan Inosuke bertemu kembali sementara Tengen menyelidiki ancaman iblis di distrik hiburan.

Tanjiro and Inosuke meet to exchange information. Inosuke claims his House has a demon, but their conversation is interrupted by Tengen. Realizing Zenitsu is missing, Tengen dismisses Tanjiro and Inosuke, not wanting them to risk their lives for his needs. The two refuse to abandon him and re-arm for battle. Shedding his disguise completely, Tanjiro approaches the Oiran of his house, who had been aware of him being a male the whole time, and bids her farewell. Meanwhile, Tengen questions the master of Zenitsu's House at knifepoint, aiming to gain information about the demon. Having just left his House, Tanjiro detects a scent coming from its direction and decides to return, only to be confronted by Daki, who has absorbed the Oiran into her obi. The two begin to fight, and Daki easily overpowers Tanjiro with her numerous obi sashes. With the impact of her attacks, one of the straps on Nezuko's box breaks, meaning Tanjiro can no longer carry her and has to leave her stationary. Realizing she will be the strongest demon he's faced thus far, Tanjiro readies himself to face Daki alone. (Source: Wikipedia)
