Curara is a teenage girl. Her hair is a short chestnut brown, with her bangs styled into French braids and fastened with two purple and white rhinestone hair pins. She has soft, hazel brown eyes. She wears the standard Minazuki Academy uniform, consisting of a gray sweater with a blue bow tied in the front, a dark gray pleated skirt, and white tights with pale pink ballet slippers.
Curara works as the class representative of her classroom. As the gifted child of an upper-class family, Curara has taken a special classical ballet class from a very young age. Though uncommon in most high schools, she is the member of the ballet club and participates in a national dance contest. At Minazuki Academy, she has gotten extraordinary marks every year. Though she has an easy-going personality, she has a surprisingly firm foundation. She is Ryuji Shimazaki's childhood friend. 
Curara is found hiding inside a locker alongside Ryuji from a monster inside the operating room. When Ayame Itou and Ritsuko Satomi enter the room, the monster starts to attack Ayame and Ryuji tries to hit the monster from behind. However, he was knocked away. Ayame then tells Curara to keep herself hidden inside the locker. After Ayame destroys the monster, Curara and Ryuji join her as they try to escape from the hospital. As they are about to escape, Curara is hit by a gas bomb and captured by a SWAT team with Ryuji, who had tried again to protect her.
