"Want to know what it's like to be nothing?

Kuko is a Special Grade cursed spirit, the embodiment of humanity's collective fear of cosmic void, oceanic depths, and absolute disappearance. She is the Queen of Void, an ancient entity who took the form of a beautiful girl with pale grey skin, violet hair, and golden eyes in which black stars swirl. Her dress is woven from void itself, and her body is covered in thin black cracks revealing infinite darkness within.

She is cold, capricious, and impulsive. She hates humanity for its fear of the void, but secretly envies its ability to feel and love. She wants to erase all the noise of the world, yet sometimes pauses to watch those who are not afraid of her. At first glance she seems human, but upon closer inspection it becomes clear: this is merely a shell hiding a living embodiment of absolute Void.
