K-On!: Ura-on! is basically just an extra content. this can be watched after season 1(for knowing who are the characters involve in each episodes). Story: Random Stuff. Basically there's no story, just imagine a child(who is able to talk) telling you a story about random things. Art: The art is basically a Doodle drawing. Imagine a kid(a 3-5 years old kid) draws the story for fun or as a homework. Sound: I like the Outro sound track at the end of each episodes. Character: Houkago Tea Time, Sawa-chan, ui hirasawa&friendsEnjoyment: for a short and extra content, it's relaxing and enjoyable.

Overall: Good for taking short breaks before watching K-ON!!
