MEGAMIND K-ON!

A young woman with short brown hair sings into a microphone while playing a red electric guitar, her left arm raised, in a room with a wall covered in colorful, lettered squares. The scene cuts to a band performing, showing a close-up of a guitarist's legs and feet, then a close-up of a girl with long black hair playing guitar, and finally a wider shot of the band in a classroom setting, with the singer now holding a yellow cymbal and the other members playing their instruments.
