Yosora Fujimitsu is accepted into North Gate National Military Academy, a school for the children of the country's elite. Endowed though he may be with the good looks and intelligence the school values above all else, Yosora immediately feels uneasy and out-of-place. He becomes determined to expose the Academy's secrets, and is thus pulled into its vortex of violence and deceit fuelled by the desire to preserve tradition at any cost.
