choose groups of either one, two or three idols at a time. After having a conversation with Kotori and the chosen idol or idols in the green room, the player chooses one of two modes the performance is divided into: a support mode and a photography mode. At this point, the player is allowed to change the player name and the name of the idol unit. Following this, the player chooses which song to perform, what stage to perform on, and which costumes and accessories a given idol will wear. Further customization allows the player to choose who sings which lyrics, and the function of the video cameras including the camera's range (close-up, mid or long) and how it dissolves into the next frame. In the support mode, the idols begin their on stage performance and the player interacts by playing a rhythm minigame in either easy, medium or hard modes. As the song plays, a predetermined sequence of controller button icons scroll from right to left towards a target icon and the player must press the correct button as the button icons pass over the target icon. The player is scored by the timing accuracy of these presses and is given one of four ratings: Perfect, Good, Normal and OK. The player's performance is also represented by the voltage meter, which increases or decreases depending on if the player successfully hits a note or not. At intervals of 50 successful hits, the idol or idols will perform a special appeal to the audience which suddenly increases the voltage meter and the overall numerical score. In the hard mode, if the voltage meter goes down to zero, the performance will end prematurely; this does not occur in the easy and medium modes. The actions of the buttons as they relate to the performance change depending on the song and degree of difficulty. For example, a button may indicate anything from a cheer, handclap, whistle, musical instrument sound, or other various supportive sounds. After the performance, Kotori shows the player a result screen, which includes the score, the number of successful Perfect, Good, Normal and OK hits, the maximum number of combo hits, and the final percentage of the voltage meter. The screen will also indicate if the overall score is a high score. Depending on the results, the player may be given additional costumes, accessories, or remixes of songs. Also,
