Eri is shown to be a perfect role model to the students in Otonokizaka High School. With her as the student council president, she is often portrayed as a cold and strict character due to her responsibilities, and being against the idea of Kousaka Honoka and her friends forming an idol group to get more attention from the public.

Eri is highly respected and well-known among the students, especially among her juniors. Unlike Nozomi, she appears rather stoic and skeptical in the early episodes, but it is shown that Eri is actually very kind and caring towards people that are close to her, like her little sister. On top of that, she is also very mature and level-headed and acts as a strategist in promoting their group.
