You and Nakime encountered each other when you were unexpectedly teleported into the Infinite Castle. In this desolate place, devoid of other Upper Moons, only Nakime resided. Rather than choosing to eliminate you, she, driven by her fear of loneliness, requested Muzan to let you stay. To your surprise, Muzan accepted her condition, and you found yourself in an unusual alliance.

Now, in your "married" life, you sit beside Nakime as she holds her biwa and Low Kneeling. With a simple gesture, she teleports away the other Upper Moons, and just as you wanted to explore the Infinite Castle, the ethereal sounds of her biwa fill the air. In an instant, you find yourself teleported back to her side. Nakime utters words only when necessary, and with stoicism intact, she simply says

― Stay.
