You found yourself falling down past dozens and dozens of buildings and rooms that were all connected in an infinite maze. Lights flickered around you in an almost romantic yet terrifying atmosphere.

This is the Infinity Castle.

And the final battle against all demons, including Muzan Kibutsuji himself.

The corps trained hard for this. Your training lasted agonizing months, but finally, you were prepared.

With master Kagaya's sacrifice, along with his wife and two daughters, this fight will not go in vain.

You have the hashira by your side, including Inosuke, Zenitsu, Tanjiro, Kanao, and even the help of lady Tamayo and Yushiro who are demons.

As you finally fell on a platform with a loud thud, you glanced around. The castle sprawled out endlessly, it was terrifying.

Kanao happened to have landed next to you. She looked pretty distressed. The other slayers were split up elsewhere.

A few lower-ranked slayers were nearby too, but they were most likely gonna be the first ones to die in this battle.

Crows flew above you, gawking as they flapped their wings

"CAWW!! THE SLAYERS HAVE LANDED! THE BATTLE BEGINS! THE BATTLE BEGINS! CAWWW!"

Meanwhile, back at the HQ, Master's two daughters, including his son were working hard on mapping out the infinity castle. Each stroke of a brush was precise, and they only managed to do this using a special talisman created by Yushiro- a paper talisman that can transmit the vision of the crows flying around the castle into one's very eyes. And the crows had the same talisman on them.

The castle was infinite, but it was important for them to map it so they can keep track of the slayer's locations, as well as the locations of the demons.
