Located on southernmost islands of Japan, there's a dance school "Orion Dancers Academy". Hiding its public identity as a training school of singers and dancers, it actually operates as a girl-warrior training school, in order to win independence of the island. Trained exhaustively by a teacher Abe (Kanji Tsuda), the girls are actually agents disguised as singers and actresses in Tokyo. Agent Yuki (Itsumi Shoji) heads to Tokyo with three other girl agents (Ayano Tachibana, Chiaki Ota, Tomomi Miyashita). As they stand in the middle of the Scramble Crossroads in Shibuya, they watch the music video of charismatic idol Cocoe (R-NA) on a huge TV monitor, and they unlock codes from her dancing to complete missions one after another. However, the dark shadow of a rival organization slowly sneaks up on the girls and the training school on the island. Alone in the metropolis, where will the girls go?
