Everyone in the world knows the name of "Dark Night" and is frightened by it, but no one has seen its true appearance. Until that day, the girl with amnesia woke up from a pool of blood. Her eyes were as clear as the first snow, but she was carrying a terrifying power that shocked the world. She thought she was a weakling who could be bullied, but little did she know that she was the sharpest blade in the world. One breath swings the sword for nine hundred and ninety-nine times, three breaths split the laws of heaven and earth, four breaths... Even the God Realm will tremble. When the layers of vest peel off, when the identity is exposed in the dark night. Those who had wanted to trample her under their feet finally saw clearly who was sitting on the throne.
"Who am I? Oh, I am your nightmare."
