Infinity Castle Arc

The Dimensional Infinity Fortress Arc is the first half of the overarching Final Battle Arc, the eleventh arc of Kimetsu no Yaiba.

Synopsis
The Hashiras rush to the Ubuyashiki Estate. Sanemi was the first one to see the mansion and was relieved knowing that he will make it just in time. However, he was wrong as before he could arrive, a huge explosion happened and burned the whole estate with all the nearby hunters witnessing it in shock. Even Muzan was surprised by Kagaya's doing as he looked calm – with a smile of a buddha as he, along with his family blew themselves.

In order to delay the regeneration of Muzan, he made the explosion more deadly by adding spike traps and while Muzan was busy trying to heal himself, he was again attacked and immobilized by a Blood Demon Art. Because of the spikes branching themselves into his flesh, Muzan tried to absorb them to escape but out of nowhere, Tamayo appeared with her left arm absorbed by Muzan.

Soon the Hashira also arrived and immediately, Gyomei revealed that the one he is fighting is Muzan and that he will not die even if his head is cut off. The Hashira, given that it was their first time seeing him were shocked at first but proceeded to attack him with their respective breaths – including Tanjiro who was with Giyu during the explosion. All of them attacked Muzan from all sides, but before they could land a blow, they all fell into the Dimensional Infinity Fortress and were separated.

While falling, Muzan mocked the hunters and proclaimed that he will slaughter them all that night. Tanjiro rebutted that it was Muzan who will be going to hell and that he will defeat him. Muzan ends up daring Tanjiro to go and get him if he can and thus, the biggest battle was about to start.
