The conclusion of Aikatsu as far as I'm concerned, with each student before hand reaching help for their dream from their mentor beforehand.
Ichigo is the star of the whole show and is easily likable, who has gained the dream of reaching a star idol from Mizuki. Mizuki being the top idol who was born to revolutionize the talent from her natural born skills. She led every step of the way for Ichigo to help her on a path to become a star in the world of Aikatsu
And finally the new wave of students who has received help from Ichigo, becoming the mentor to a new generation who can define being an idol in their own way.
This movie isn't for everything because of how cheerful it is, and the musical numbers animated by CGI animation, but if you love hard work and determination to becoming the best, this movie will be for you.
