The team was started by Prism Stone's owner, Chisato Ibara, in order to create top class Prism Stars for an assessment which is currently unknown to the members themselves. They were selected to run a store named Prism Stone in order to grow as a person. Naru was selected as the manager after auditioning and soon invited Ann and Ito as the rest of the staff. The three soon joined the Dreaming Session tournament and decided to become Prism Show comrades under the name Prism Stone in order to promote their store. After many events involving Prism Shows, the Try! Groovin' Session was held where Chisato decided to rename the three of them. Ito suggested the name Rain, as it included the initials of the three girls and Rinne. As Ann thought it was too gloomy, Naru decided to name themselves Happy Rain and they won the tournament, becoming one of the most popular units around.
After the events of the Over The Rainbow Session, the three girls graduate from Prism Stone but decide to continue as Happy Rain.
