She attends Nanairogaoka Middle School in Nanairogaoka Class 2-2 along with the other Cures. Miyuki is a bright, kind-hearted, and energetic girl who loves fairytales. She is always happy and optimistic but seems occasionally naive. Miyuki is also really clumsy to the point where she sometimes ends up hurting herself when she gets overly excited, such as hitting her head after falling back. Multiple running gags in the series include Miyuki falling flat on her face after she randomly trips and her always getting hit in the face by random objects such as Candy and Pop's storybook.
