Kageki Shojo!!

Ai Narata, a former member of an idol group called "JPX48," applies and gets accepted into the prestigious Kouka School of Musical and Theatrical Arts (whose annual admission is no bigger than 40) to become a stage actress. She tried to travel incognito in order to get to the school without drawing attention, although her cover gets blown. Her fame (and associated controversy that caused her "early graduation") preceded her upon reaching the school, making her an outcast from the get-go. And just as she is attracted to the "cursed" sakura tree within the campus, a tall girl reached out for her ticket that got blown into one of the tree's branches, then asked her if she could take a picture of her under the same tree. But Sarasa Watanabe, the tall girl, earned some stares from the people gathered at the courtyard--which includes the daughter of a family of stage actors and one who passed on becoming a prima ballerina in favor if enrolling at the school--when she declared her intent to become the "top star" someday.
