A tomboyish girl who was Jing's close friend during his childhood, Cassis talks and dresses like a boy to keep the Spirit of the Forest from discovering her true gender. She possesses a masculine and robust personality, along with long blonde hair that she somehow conceals under her cap. Her weapon of choice is a baseball bat.
Cassis harbors feelings for Jing but struggles to be honest about them. Following Jing's birthday party, she is abducted by the Spirit of the Forest. This event sets the stage for Jing and Kir's first adventure together as they set out to rescue her.
