"Idol" is the "hope" of the world. Nurturing such idols, there is a genius producer called Makoto Terada who sends out a number of hit songs to the world. But even for such a brilliant genius living in a glittering world, "death" comes equally... A disease named "cancer". To Makoto who was putting everything into idol training, he can't afford to consider his own condition, when he noticed, his whole body is already fucked, there is no way to save him from the reaper except "miracle" It was a desperate situation... However, Makoto choose to fight for that despair. ...But his choice is not “medical treatment” he keeps going on being a "Producer" until the end. Among the idols that he produces, there is 5-Idol unit "SIGNUM" which can be said to be a masterpiece. It’s just their passing point, successful dome concert is their current destination, and that is his only hope to live.
