An iDOLM@STER Cinderella Girls character in the Cool (Blue Diamond) category. Yoriko is an intelligent young woman who underestimates the potential of her physical beauty. She wears glasses in her everyday life (which tend to be large and bulky, as opposed to sleek and fashionable), but takes them off to perform onstage. Yoriko is also depicted as one of the smarter idols, and tends to be reserved and quiet. She enjoys wearing her hair back in headbands.
