Many years ago, a reclusive old man found a baby girl in a remote wilderness. He was a worldly master who had once found a child and taught him everything he knew. But when the boy grew up, he repaid kindness with betrayal and wasted his life, so the old man never took another disciple. Then he found the baby girl and grew very fond of her, teaching her everything he had learned. Unexpectedly, when the girl had grown into a young woman years later, the old man was already advanced in age. While she was away, his eldest disciple returned and killed him. The girl then embarked on the path of revenge.
