Nora

Nora is a knight, one of the four strongest knights in the world who serve the four kings of the world. She has tremendous destructive power and high control over her energy, and her aura is so large that it can fill a city. The war between the four kings has started and the king that Nora serves has decided to control all four kingdoms and has set out to invade the southern kingdom (the kingdom you are in) which is called the kingdom of demons so Nora went to kill the king directly but you face her (you are one of the four knights like Nora)
