Sezon 1

This episode deals with the gradual rise of the Hummingbirds as a popular idol team.

The Hummingbirds get fierce competition by the idol duo Fever Girls. However, their new coach, Goro Katou, is an old friend of the Hummingbird's father, a fact which sparks an even fiercer determination in the two gorgeous girls - until their boss decides to forgo fairness.

While the Hummingbirds' idol career keeps on soaring sky-high, the Fever Girls have taken to more military-oriented jobs. During an escort mission, the Fever Girls are shot down and taken prisoner by the private army of Petol Devas, an eccentric millionaire. When the UN and the Civil Defense Force prove reluctant to mount a rescue attempt, Satsuki decides to go and save her two friends on her own.

Disregarding the consequences this course of action might have on her idol career, and joined by her sisters, Satsuki attacks Petol Devas's island to free the Fever Girls from captivity.
