The students there have the freedom to wear any hairstyle and bring any personal effects they desire. While seemingly a paradise like school, the truth is that only the most superior of students receive favourable treatment. Ayanokouji Kiyotaka is a student of D-class, which is where the school dumps its ‘inferior’ students in order to ridicule them. For a certain reason, Kiyotaka was careless on his entrance examination, and was put in D-class. After meeting Horikita Suzune and Kushida Kikyou, two other students in his class, Kiyotaka’s situation begins to change. Based from the popular light novel series of the same name!
