Once upon a time, she was a talented girl among the splendid houses of Qu Mansion. She drank tea and listened to the rain, unaware of the sufferings of the world. Overnight, the family collapsed and blood relatives withered. From a prisoner to an outlaw, she took off her skirt and hid in the dark night. Kyoto is still prosperous, but it hides a destructive whirlpool. When talent turns into wisdom, when kindness is sharpened into a sharp edge, she deals with young talents and knights, and joins hands with the mysterious organization "Shadow", vowing to carve a bloody path for her family in this deadly situation.
