The number one-ranked third-year American Pandora at East Genetics known as Godspeed of the East for her Quadruple Accel technique and considered to be the most powerful Pandora at her academy. Despite having the highest synchronization rate with Kazuha's Stigmata and receiving three of them, Cassie does not feel she is the most powerful Pandora, and believes herself to be undeserving of the title after she fought with Satellizer during the Levon incident, which made her realize how weak and scared she was compared to Satellizer's determination and refusal to give up. As a child, she wanted to be a novelist, but her father forced her to attend East Genetics to become a Pandora for his political career. Her encounter with Satellizer made her change her mind, in which she decides to settle down with her Limiter Kyoichi, who she is also in love with.
Spoiler...When four Type S Novas attacked East Genetics, she, along with several of her Pandora comrades (including Milena) were absorbed by one the Novas, infected, and turned into Nova Form Pandoras. She, and the other Nova Form Pandoras that were affected, launched a full-scale attack on West Genetics. She fought a long and grueling battle with Satellizer, nearly killing her until she was beaten by the latter's newly-acquired Nova Form, having both of her arms severed and the source of her infection destroyed. Her Volt Weapons are a pair of arm-mounted blades called Falchion.
