Quick Transmigration: Endless Dark Nights

She is the embodiment of malice in this world, hated by the world itself. Yet the world has no choice but to depend on her to keep its energy in balance.

She hates this world just as much, but she has no choice. She can only let her darkness run free and sink into ruin alongside the world.

I'm terrible at writing introductions: The protagonist can be male or female. Born from malice, they can change gender at any time, depending on their mood.
