When "Birdie", a dance unit, debuted three years ago, it became a giant success in the Japanese idol industry. "Birdie" is made up of three members (Kazuya Nakajoh, Takashi Kanzawa, and You Onozuka) who were recuited after auditioning with an agency that produces idol groups. They are kept at the top of the idol entertainment world by participating in such things as drama performances and quiz shows. Things might take a turn for the worse however when one of "Birdie"'s managers arranges for a famous ballet dancer from New York to be their new choreographer (Tsubaki Kyouichi). This change will result in big changes for "Birdie", but will they necessarily be good ones? Will the individuals become heavily involved in Kyouichi's bad influences?
Birdie, like most boy's love games, is in visual novel format. This game is different in the sense that it has a multiple character viewpoint system, so that the player can focus on more than one individual, and can change the viewpoint in the story from day to day. This means that there is no set character, and the player can view things from the perspective of all the involved characters.
