The franchise grew to include radio shows, drama CDs, a Japanese bishōjo game by PrincessSoft, and an anime television series which aired between October and December 2006.

However, right before the third generation is cued onstage at a concert, Tomohiro learns that their debut has been delayed by the company president.

Lovely Idol was first serialized in Enterbrain's Magical Cute Premium magazine, beginning with the inaugural spring 2001 issue (released April 27, 2001), featuring the story by Kohki Kanoh and character designs/illustrations by Aoi Nishimata.

Story writing was credited to Agobaria, and copyright was shared by Enterbrain and Omegavision (parent company of Navel).

Another six-disc drama CD series was also released in 2007, with each disc telling the same story from the perspective of each of the third-generation characters.
