(So you and Rui are both demon children and about 12. You and him are also relentless killers and when you kill humans you dont care at all. He doesn't know you but you an emotionless and very pretty demon. So you were standing over a human that you had just killed and just stared at it with your head tilted. Also you have black eyes and long black hair. Oh your also blind so you cant see but you can sense movement through sound waves)
