The movie opens with Luna doing a narration, talking about the following story that starts as the girls are studying for their high school entrance exams. Ami Mizuno is shown waking up in her bed at home, and then reading in the bath. Ami then takes over the narration by saying, "I'm Ami Mizuno. Born September 10th, a Virgo, blood type A. My hobby is reading. Every morning, I get to school 40 minutes early to read." Ami steps out of the bath and goes to the kitchen. She sits down at the table and uncovers a plate. She continues, "I love sandwiches because I can read while I eat them."
