The Sunrise Countdown Arc is the second and final half of the overarching Final Battle Arc, the eleventh and final arc of Kimetsu no Yaiba.
Synopsis
Tanjiro Kamado regains consciousness and sees the night sky above him, finally back at the surface after Yushiro worked to get them all there. Realizing that they are in the middle of the city Tanjiro panics and Kiriya Ubuyashiki sweats and says that they were all flung much further than he had expected they would be. He asks his sister how long it is until dawn and she informs him that there is still an hour and a half left until daybreak as Kiriya's eyes widen at the knowledge that there is still so much longer left.
A crow tells the Demon Slayers how much longer they have left till dawn and taking note of the fact, Tanjiro looks around to confirm that his comrades are doing alright. Relieved that the Hashira who had been with him are all safe, Tanjiro moves out to try and sniff Muzan out. Suddenly the Demon Lord bursts through a pile of rubble, sending it flying in all directions. Enraged, Muzan taunts the Demon Slayers and dares them to keep him there until dawn if they could even do so.
