Sana Kurata is a cheerful, popular and energetic 11-year-old child actress who enrolls in a regular school only to find out there is chaos in the classroom, led mainly by an aloof boy named Akito Hayama. At first, the two come in conflict with each other because of their opposing ideals, but as they get to know each other, they start helping each other out in Akito's family life and Sana's career, as well as helping their classmates and peers.
