Qin, Ya

秦雅 / 星空カリナ

Qin Ya is the twin sister of Qin Ze and is regarded as a beautiful top idol singer. She is interested in achieving her long-held goal of becoming a successful actress and had originally intended to become a singer to help inspire her brother to return to the musical stage himself. However, she is poor at taking care of herself and can sometimes be lazy and keen to avoid work. Because of her outwardly confident attitude, many people in the entertainment industry dislike her.
When Ya and Ze were young children, she considered Ze to be somewhat of a "tyrant" who worked too hard. She eventually grew up to have a somewhat selfish and whimsical personality toward him, but she cares deeply for him and his success as a singer. She enjoys having Ze dress up as and pretend to be her, while she also likes dressing up as and pretending to be her brother herself.
Ze's and Ya's Japanese names, Eita and Karina, come from the Eta Carinae Nebula.
