In a quiet neighborhood stands a charming house with an unusual secret: its entire basement contains a professional-style dance studio. Ami, Reiko, and Sora are three 17-year-old teenage friends who share a passion for dancing and singing. Their specialties are tap dancing and Irish dancing, but their greatest strength comes when they combine their dancing with three-part vocal harmony. Each episode blends everyday teenage life with dance rehearsals, comedy, emotional drama, and full-length insert songs. Tap shoes become percussion instruments, Irish jigs become energetic dance numbers, and the girls’ voices frequently build into rich three-part harmonies.
