Trivia

 * Initially, the anime was supposed to last one season- until episode 48, but the series' massive popularity overturned this idea and thus it has continued.
 * Till now the Oracion Seis arc has been the longest arc spanning nineteen episodes and the Macao arc has been the shortest arc spanning only one episode (the first episode was not of Macao arc).
