A sweet surprise for a special underclassman...
K-On! started off as a manga in 2007, written and illustrated by Kakifly, who is a mangaka/guitar collector. Kyoto Animation (The Melancholy of Haruhi Suzumiya, Clannad, Lucky Star) adapted the title into a 13-episode anime series in 2009, which later got a second season of 26 episodes in 2010, and the movie I am reviewing now. This movie was directed by Naoko Yamada and released December 3, 2011.
