This anime is based on a 1999 radio drama about three very different girls, Akari, Yuki, and Nozomi, who go to see top pop idol Reika's concert, and their lives are greatly influenced by it. Akari was raised in a religious household; she is bright and cheerful, and she adores Reika. Yuki is a strong-willed young woman who ran away from her home in Hakodate. She is working in the concert hall where Reika will be performing. Nozomi comes from a wealthy family in Kobe. She has one of the concert's VIP seats. The three girls are so moved by Reika's performance that they all enroll at the Akiba music school and strive to become musicians.
