Rhythm/Rizumu is a student who goes to the same school as Aira. She was born on September 3, 1997. She has horrible grades and even says that getting a 70 would be a miracle for her. But she is very good at dancing and attends a dance school for Prism Stars named "Pretty Top". She always tries to do her best and wants to become the Prism Queen to perform the "Aurora Rising" thinking that it will bring her mother back, the legendary prism queen Sonata Kanzaki who disappeared after performing the legendary jump. She sometimes tries so hard that she forgets what the prism show is really about. She has orange hair and light brown eyes which is noted by Aira's mother to look exactly like how Sonata looked like when she was younger. She seems to be knowledgeable about love from a certain book of hers.
