Syllabus of Oshie

One day, on a whim, Matoi buys an old college entrance exam study guide. Upon opening the book, a cheerful, long-haired girl magically appears, claiming to be her new in-home tutor! Despite her family's acceptance of the magical girl, called Oshie, Matoi is thoroughly unhappy about her new circumstances. As a first year high school student, she wants to spend her time hanging out with her friends, not being forced by an overzealous magical tutor to constantly study for her college entrance exams. She's even more horrified when Oshie points out the fine print that she missed. In opening the book, Matoi has apparently agreed that she will either be accepted into her chosen college... or die!
