Trivia

 * Similar to drummers in the 19th century and 17th century, they may serve as a form of communication to relay messages in the army.
 * Judging on their abilities and name of their group, they're most likely a band of bards, who use the power of music and song to produce magical effects.
 * While they appeared in the anime they did not announce themselves like they did in the light novel.
