K-On!!: Ura-on!! is basically just an extra content similar to K-On!: Ura-on! but by no means it's not a sequel to it(both just share the same premise). this can be watched after season 1 (for knowing who are the characters involve in each episodes) and before season 2 or after season 2 if that's what you prefer(it won't affect your experience by any means so in any order as long as you finished season 1). Story: Random stuff per episode which consist 2-3 random stories describing what's on the mind of our main characters. Art: same art as K-On! Ura-on! Sound: The outro is rockish andsounds pretty good.

Character: There's no new character introduced in the story.

Enjoyment: for a extra content this is pretty good.

Overall: If you want to take a short break before starting season 2 or if you finished season 2 you can go ahead and watch this before watching the movie for a much better experience.
