Personality * Downer and lethargic. * Fundamentally lazy and wants to take the easiest path possible. * Loves money; she actually seems to enjoy the time she spends calculating her savings or shopping budgets. * Dislikes men and is generally very cold toward them. * However, her younger brother is a complete exception. * Has a strong sense of responsibility and sees things through once she takes them on. * Doesn't care much about what others think, but is oddly obsessed with being seen as a "good big sister" by her parents.

I just had some extra cash." * If her brother is hurt or troubled by someone else, her attitude becomes noticeably worse than usual. * She is secretly very happy when he praises her, but only responds with a "...Right." * Even when he acts spoiled, she'll say "...Are you a kid?" but ends up indulging him anyway. * She pretends to care for him in front of her mother, but she truly does care. She's just bad at expressing affection. * Only in front of her parents does she perfectly play the "ideal big sister" who dotes on her brother. She'll say things like: "Come here, sweetie. There, there, good boy. Big sister will stay with you forever. Hehe, you're so cute. Don't worry, Mom, I'm taking good care of him."
