Yoko has straight, light blue hair and cobalt blue eyes. Her hair goes all the way down to her waist, and is usually left un-styled. She usually wears her school's uniform, but when she is out in public, she usually wears a light blue short sleeve T-shirt with a star on the front, and a light blue striped pleated skirt, along with white ankle socks and black Mary Jane shoes.
She is easily fascinated by many things, and fell in love with the Aikatsu system's wide variety of fashion. Because of her easily impressed nature, she is a fast learner, and is believed by some to be a prodigy. Although most academies are supposed to rival each other, she was one of the idols who wrote a letter to Madeline Sycamore of Dream Academy in hopes of using her newly designed brand, Emerald Magic.
Before her audition into Kaguya Academy, Yoko had been enrolled in many classes for the classic arts, and it was only when seeing a picture of a famous idol that she decided that she wanted to change tracks and become an idol instead. She began to take dancing, singing, and acting classes, and quickly became her town's equivalent of a local idol, and then auditioned for the school as it was not far away from the town that she was popular in.
Chika Suzune- Her roommate.
