Hikari no Dentetsu is about Hikari Kamijou, a fifteen-year-old junior-high-school girl who develops a passion for the sport of rhythmic gymnastics ever since she saw her idol, Diliana Gueorguiva perform and win a contest of rhythmic gymnastics at a young age. When she meets her idol, she proposes to train Hikari in Bulgaria when she is professional rhythmic gymnast. Hikari accepts and quickly began to train in the sport. Many years later, Hikari is training very hard to become the best rhythmic gymnast in her school. She soon becomes a member of her school's rhythmic gymnastics team.
