Mikagura Gakuen Kumikyoku

Eruna Ichinomiya is a junior high school student in her third year who has yet to choose a high school, spending her time avoiding school and gaming at home. One day, a pamphlet from Mikagura Private Academy, given to her by her cousin Shigure Ninomiya, features a photo of Seisa Mikagura that captures Eruna's attention. Believing it to be destiny, Eruna resolves to enroll in Mikagura Academy. However Eruna finds out that Mikagura Academy is a place where only cultural clubs are present and that it has a rigorous battle system in which students with unique powers must compete against one another as representatives of their respective clubs.
