Unaired anime bundled with the limited edition of the 9th volume of the manga.

On days when Sunao is sick, or not feeling like going to school, she is called to take her place. She was born to this world when Sunao wished to have a substitute. No one knows that she exists, but she tries to do her best for Sunao whenever she is called. One day she talks with Sanada, one of her classmates. They become friends, but soon he notices that she is different from the original Sunao...he was the first one who did. She tells him to talk with her only when she has her hair half-up. Sanada does like she told him, and they enjoy their time together. As they become closer, she realizes that she has special feelings toward Sanada. But she doesn't know what will happen to her...if she, a replica, falls in love. (Source: Kadokawa)

This anime is based on a 1999 radio drama about three very different girls: Akari, Yuki and Nozomi; going to see the concert of top pop idol Reika and by going to see this concert their lives are greatly influenced by it. Akari was raised in a very religious background, she is bright and cheerful and a big Reika fan. Yuki is an independent girl who ran away from her home in Hakodate. She is working in the concert hall of Reika's performance. Nozomi is the daughter from a wealthy family in Kobe. She's got one of the VIP seats at the concert. The three girls are so inspired by Reika's performance, that they all enroll in the Akiba music school and endeavor to become pop idols themselves. (Source: AnimeNfo)
