Natsuka is a member of one of the richest families in Japan. Because of this, she was often spoiled as a child. Sick of her selfish antics, her father pulled her out of her elite private school, hoping that being among normal highschool students will make her realize how good she got it. Unbeknownst to him, this change had an adverse effect on Natsuka, making her feel superior to her commoner classmates.
