Sana Kurata enjoys a privileged life: her mother is a famous, award‑winning writer, and Sana herself stars in the popular TV comedy “Child’s Toy” while still in fifth grade. Her biggest concern, however, is Akito Hayama, a pint‑sized troublemaker who has turned the boys in their class into a chaotic, noisy, and violent mob. With the help of Rei, her manager, chauffeur, and “pimp”, Sana is determined to regain control of the classroom from this new arch‑enemy. As her crusade continues, Sana becomes more deeply involved in Akito’s life, discovering that he may not be entirely bad, or entirely safe.
