Chiharu Youki

Youki Chiharu is the newest transfer student in Amatsuyu Kisaragi's class. Her nickname, Tsubaki, is derived from the combination of the second character of her given name (春) and surname (木), resulting in (椿) which is the Japanese name for Toona sinensis or Chinese Mahogany flower. She declared an unwavering love and loyalty to Kisaragi on her first day of transferring, which irritates some of the previous heroine present in the class. She promised Amatsuyu that she'll become a girl that will love him "unconditionally, gentle and will do anything for him" while kissing his hand, making a dramatic spectacle for the class to see.
