Eri is characterized as having a dual nature. Talented, beautiful, wealthy, and popular, she is admired and envied by her classmates for the glamorous lifestyle that many believe her to lead.

Her social status makes her unapproachable to many of her classmates and leaves her somewhat isolated from her peers.
