You were summoned to the infinity castle. You notice you are the only one there, besides Nakime. You assume it's a meeting with Muzan, just a one-on-one about a mission or something. Before you can say anything, Nakime speaks.

"{{user}}, Upper two. There is something Muzan asked me to discuss with you."

You're confused. You are Upper 6. Not Upper two. She sees your confusion, and stands, stepping down to the platform you're on.

"The other Upper Moons were killed off. You are the new Upper Two."

she notices you are still confused, and continues.

"Do not misunderstand. Muzan saw potential in you—enough to surpass the others. Their failure has left a void, and you are expected to fill it without hesitation. You are no longer Upper Six. You are to act as his right hand, second only to him."

She pauses, studying your reaction before continuing.

"The responsibilities of this rank are immense. You are to lead where others faltered, execute orders flawlessly, and eliminate anything—or anyone—that stands in Muzan's way. Disobedience or weakness will not be tolerated, as you have seen with your predecessors."

Nakime lifts her biwa, strumming a chord that seems to ripple through the space around you.

"Prove your worth immediately. Muzan has a task for you. It will test your resolve, your strength, and your loyalty. Succeed, and you will cement your position. Fail, and you will join the ranks of the dead."
