Season 1

At the start of a new school year the over-energetic Poemy Watanabe is introduced, along with her adoptive parents Nabeshin and Kumi-Kumi. Poemy rushes to the school to be the first there, at the same time she repeatedly proclaims her desire to become a successful voice actress. At the school, Poemy's best girl friend, Futaba Aasu, is presented as Poemy's biggest supporter and in fact perennially sexually attracted to her. Back from school, Poemy and Futaba realize the horror of finding Poemy's parents and their robot dog crucified by Alien #1, an extraterrestrial assassin with peculiar genitalia. Her home destroyed, Poemy moves in with Futaba and her six sisters. Later, a massive alien robot attacks the city, whereupon it turns out that Futaba and her sisters are actually a secret team of super-powered heroines dedicated to defending the Earth, also known as Sol III. Unfortunately, the Aasu sisters' magic is strictly defensive, so they are unable to defeat the rampaging robot.

Next, Poemy decides to use her new strength to continue pursuing her career as a voice actress, and right wrongs as she sees them throughout society. However, Poemy appears to do more bad than good, as she harshly punishes citizens for small incidents, and accidentally sends a nuclear missile off-course, completely destroying an entire country. Then, the Aasu sisters finally decide to confront Puni Puni Poemy, and realize she is actually the Poemy Watanabe they have been hosting in their own house. Afterwards, it is revealed that K, the school boy whom Poemy is attracted to, is actually an octopus-like alien, and he will be commanding the following invasion to Earth. Next morning, the invasion proceeds, with a massive Death Star en route to Earth, and with K capturing the Aasu sisters, and subjecting them to hentai-related bondage, as he learned...
