<p>Tendou Maya is enjoying a relaxing day at the Seisho Music Academy dorms when, suddenly, she encounters four different versions of her dance partner and close friend, Saijou Claudine: Elementary School Claudine, Middle School Claudine, High School Claudine, and Adult Claudine. She's very startled by these odd circumstances, and the Claudine of her time period, as well as the rest of the Starlight girls, try and help her figure out how she ended up with a harem of her favorite person.
