She hasn't told anyone that her mother was the legendary Prism Queen.
Rhythm is ambitious, her dream is to perform the "Aurora Rising" one day so that she can bring her mother back. She's good at dancing. She always tries to do her best and follows her dream. However her grades are shown to be very bad. She is the type of energetic girl who doesn't care about he schoolwork. It is stated that she may be the type of girl which love becomes power and fuel for her. She also seems to be quite knowledgible about love from a certain book of hers.
Aira and Rhythm meet the first time, in the mall, where they both run into each other. Later they perform together in their first Prism Show.
Aira helps Rhythm with her great fashion sense and picks out an outfit for her, which she wears while she performed her Prism Jump. Rhythm wanted to know, how Aira was able to do the Prism Jump.
After some time the two become good friends, they both get a scholarship for the dance school, where she also meets Bear-Chi her coach. It is revealed later that her mother was the legendary Prism Queen Kanzaki Sonata. She is also shown to be closest to Hibiki from Callings. She blushes a alot around him. Hibiki seems to find Rhythm interesting. Just like Aira and Shou they both are shown to have created a relationship too in episode 18 of the anime.
Rhythm has long, orange hair that is tied on the right side in a small ponytail with a heart hair tie and brown eyes. She usally wears boyish clothes, she has a bad taste in fashion. It seems like she hasn't cared about fashion, before Aira made her an outfit. She like to wear parkas because they are easy to run and dance in. However she does wear miniskirts and long stockings. It is stated by Aira's mother Omi Harune that she looks just like Sonata when she was younger.
During her first Prism Show, Rhythm tired her best but couldn't satisfiy the crowd, because she couldn't do a Prism Jump. However she revealed that she was good at dancing.
In the second show, Rhythm wasn't allowed to wear her perform costume, instead she wore the outfit Aira chose for her. After some time, she heard her costume sing, and managed to perform a Prism Jump, called "Heartful Splash". She and her partner and best friend Harune Aira perform the Prism Show together. In the beginning she just wanted to do the Aurora Rising and was so stubborn but then she started to enjoy the Prism Show. She placed second in the Tiara Cup and is performing in the Summer Queen cup with Aira because they are best friends. She will probably continue the Prism Show because it is so fun.
