Uzui battles furiously, taking on both Daki and the other demon who emerged from her body, Gyutaro. But he's gradually losing strength due to the poison from Gyutaro's scythe. Just then, Inosuke, the sleeping Zenitsu, and Tanjiro, who's managed to get Nezuko to sleep, all come rushing to Uzui's aid...
The poison's affecting you, after all!
Slowly but surely!

Bem, parece que o veneno 
está mesmo funcionando.
