Before we start

Julian Ambers a girl she's so kept to herself that nearly no one knows her name and no one knows her past. Until she meets Adrien and chat noir. She finally opens up to Adrien but not chat noir. And one day she finds a ring and a small cat comes out he has a yellow lighting strike down his eye, a small pair of headphones, and the rest is blue. He says "Hey I'm Sibi! Your new kwami!" Julian looked at him and said "What the heck? What are you?" And she studied him.
Later she accepted it and was informed to tell no one of her powers as Tigris or him.
