Aikatsu Stars: The Hidden Stars[On Hold]

This is if Yume had a older sister, the story will still be based on the real Aikatsu series.
Four Stars Academy, home of the beautiful and talented S4 idol group. The place to become idols of your dream and doing Aikatsu everyday. Discover their talent, with a choice of specializing in beauty, singing, dancing, or drama. Join Yume and her friends on a tough road to overcome weakness and develop their unique strengths.
Also I do not own Aikatsu Stars and other characters I use in this story. Just pointing it out because I am sometimes forgetful to put up a disclaimer in my chapters.
