As time flows by while their activites continue, Ichigo, who is now in her third year of Starlight School's high school divison, is starting to become aware of her graduation that is coming in half a year. She knows that even after she graduates, she'd like to continue her idol activities. However, to pass the hurdle towards her graduation, there is one more fork in the road lying ahead.
