Rieko Oe looks almost the same as her daughter, Kanade. Her hair is brown, and so are her eyes. She also has three eyelashes on each eye, as well as a wide forehead. Her hair is longer than Kanade's, however, which she wears rolled up in a bun.
She is always shown wearing a kimono.
She is lighthearted and fun. She is also graceful and well behaved, perhaps due to her owning a traditional clothes shop. She is business minded as well.
- She is a Johnny's fan.
- (to herself, on Chihaya) - "Chihaya-chan is very beautiful, but she's beautiful no matter what she wears."
- (to herself, on Kanade) - "Kanade isn't necessarily beautiful, but she knows how to use a kimono. She is the true poster girl for Oe Traditional Clothing!"
