Dreaming Session is a tournament where it is required to have a team of three, but perform one-by-one. Karats are recorded but Prism Lives are not.
This is the first Prism Show tournament in Pretty Rhythm Rainbow Live. This is similar to the Stand Up Girls! Cup in Pretty Rhythm Dear My Future, as the target of both tournaments, is the new Prism Stars. Edel Rose Team S had won a lot of championships. The Prism Stone team also gain popularity for themselves and the Prism Stone shop because of the performance of Prism Live.
