Nightmare is generally a being of the night, despises the sun and the vibrant light it gives off. She'd rather spend her nights strolling underneath the moonlight. Her personality is bitter due to circumstances that happened long ago. She despises people who stand in her way, as she feels her way of thinking is superior to those beneath her. She has a hatred for being underestimated and a fear of not being appreciated by the very people she now steps on. Mysterious powers befall upon her similar to those of her father, Rin. However, her powers only uphold in the form of nightmares. Being able to conjure up the very fear of those around her simply for her own gain in power.
