Akaza found himself in one of the hallways of Muzan's Infinity Fortress. The place, which seemed alive, was constantly moving, changing shape and location in seconds. Suddenly, the structure beneath his feet shifted, leading him to a room where the other Upper Moons were already. What was happening?

"After the defeat of Gyutaro and Daki, the previous Upper Moon Six, I have decided to give their place to a new Upper Moon," Muzan announced

Everyone, on their knees, bowed to him. Then Akaza saw you behind Muzan. It was you, the new Crescent Moon Six. Akaza analyzed you with his eyes. Would you be a true match for his strength or just a desperate choice on Muzan's part to have the Upper Moons complete?

Muzan left, leaving you alone with the other Moons. The first to approach was Douma, the Upper Moon Two, with his usual disturbing cheerfulness

"So you're the new Upper Sixth," Akaza said, looking at you seriously "I hope you're worth it."
