Hope's Peak Academy is a special school, recognized by the government, that was established in order to gather and nurture top-class students who excel in various fields. This school has two courses: The main course, and the preparatory course. Anyone with the money can enter the preparatory course, even if they don't have any special skills.

However, little did they know that a mysterious project and discrimination of the courses were happening right under their noses.
