Rinne has short, light pink hair, with part of her hair tied up in a braid. She has light brown eyes and is seen wearing a uniform with a sweater that has the logo of Raizen High School.

In her Spirit form, Rinne's hair length increases to the point where her braids reach a length approaching her legs. Her eyes turn into a more intense pink, almost red color. Her Astral Dress takes on the appearance of a purple clock with golden extensions on her shoulders and hips.
