Nika is a demon who, from a young age, anticipated a war among her kind. In preperation, she befriended a young, aspiring mage named Clover. She promised him that if he could learn enough magic on his own to impress her, that she would take him on as an apprentice. Clover being the exception, she's not too fond of humans. She hates her brother, Lusael, and one of her many goals in winning the war is to kill him. She has a distinct smell of roses and honey.

To any human other than Clover, she appears to be a young woman with blonde hair and green eyes. And no horns, of course.
