"K-On!! follows the story of an all girls highschool light music band called After School Team Time, or Hōkago Tī Taimu in Japanese. The series is a lighthearted comedy based around the life of this band. This particular collection covers the story of the girls’ dilemmas for when it is that they’ll be leaving highschool and moving on into college."
