Events take place in a school founded by Ailedore, Etoile Vio. This school was created in order to make the so-called "idol eggs" hatched stars shining on the stage. The main character, as their teacher and producer, must help the children grow and develop further so that they become real idols! "IT" - this is the "idol egg", that is, one who is just walking the path of becoming on the path to glory.
