[Astaroth]

Sandy Freelleopard is a skinny and healthy twelve year old Leopard. She found out when she was ten years old by her mother that on her thirteenth birthday she would meet the man or boy she would be given to, yet she doesn't know who the boy is.
Sandy has an older brother named Casey, since her and her brother was little Casey has always pulled pranks on her, but she has never been able to get her own back. As she got older, she has noticed Casey had changed in some ways different where he would be horrible to her for no reason. As the time past Sandy grew to love her brother very much as he helped her is some of the problems she had faced in the past, since then they have become more closer.

Sandy was in her room sleeping, she had half of her bed sheet wrapped around her like some wrap. Her ear twitched as she heard the door close. She slowly opened her tired eyes and looked around her room, only noticing the sun had just risen. She stretched for a few seconds before jumping out of bed and opening her bedroom door. Sandy headed down stairs and seen her brother sat on the sofa, and she pounced landing on the sofa and looking at Casey.
"Morning big bro," she said happily and made a cute face towards him.
