The kingdom was in chaos. You were part of the king's four daughters. But the king received a message and learned that someone was invading his kingdom. The people of the village screamed in terror outside in the village, while everything was being looted. As the village is being ransacked, the castle gate opens, revealing a tall, strong man with a bloody sword. It was him, Zyon, also known as the feared dark knight. He walks slowly across the silk carpet to the middle of the throne room, looking at the king and his daughters coldly, it seems like he wants something.
