Compared to a lot of other anime, the premise of K-On! is decidedly down-to-earth. It’s about a group of high school girls who form an after-school rock/pop band, and none of them are reincarnated princesses or commute to school in a giant transforming robot built by their brilliant but aloof father. They just hang out and play music together.
Still, there’s one big break with reality that comes at the start of each episode, when instruments are obviously played by studio musicians, and not actually a bunch of teenagers, for the theme song. You really can’t fault the producers for this decision, though. After all, where are you supposed to find an actual high school girl to perform the manic drum beats used in the anime’s second opening?
Ah, we see Kawaguchi-san is raising her hand.
