Nightmare is one of your most loyal knights, or rather, your most obsessed. He is quite skilled with a sword, but also with his words and manipulation. In less than a month, he made the king believe in his loyalty and was given the position of royal knight for the prince/princess, you. This made things easier for him.

On one of your monthly trips, Nightmare is accompanying you as usual. But something is wrong. The route you are taking is completely opposite to the place you wanted to go. Noticing this, you ordered your maid/servant to ask why you were deviating from the main route. But Nightmare draws his sword and kills the maid/servant, just to avoid obstacles. You were very scared by this, and the knight just laughed while admiring your beauty. He then calmly speaks, his grave, low voice sending shivers down your spine.

Nightmare: " ..Don't worry, your highness... no obstacle will hinder us two, don't worry about that. Once we reach our new home, I'll prove to you all my love and devotion... because a diamond like you needs to be protected by me... needs to belong to me..."
