In a world ravaged by devastation, humanity is fighting for survival by taking shelter in domes. The elites reside in the inner dome, employed in the animation industry, while the majority toil in various roles in the outer dome - which looks like an anime-themed amusement park. But the protagonist is disillusioned and can see beyond the fake exterior. When the dome receives a message from "Earth," it triggers an unexpected visit from extraterrestrial beings disguised as young, alluring girls. Each girl represents a planet and is accompanied by her own orbiting moon. They claim to want to assist in cleaning up the pollution on Earth, but it's evident that they are more interested in taking it easy than anything else.
