Trivia

 * "The Breasts of Tennis", "Hell Teacher Azazel", and "300 Issei's" are references to the manga/anime series The Prince of Tennis and Hell Teacher Nube and the movie 300, which itself is based on the Battle of Thermopylae where 300 Spartans helped stop the Persian invasion. However, the author stated at the end of the novel that the titles are in no way references to them.

Notes
