Slice of life about a group of highschool girls in Tokyo, where there is a giant dormant UFO floating above the city that randomly appeared one time and has just been floating there. It's a funny juxtaposition against the normal SoL tone and story the anime takes on.
"Three years before the events of the story, on August 31, an alien spaceship appeared over Tokyo. Although it has not attacked, the Japanese government, seeing it as a potential threat, unsuccessfully tries to destroy it. The situation leads to a
cold war between the humans on Earth and the invaders in the mothership above the Tokyo skyline. There is further conflict between political groups who want to eliminate the aliens, called "warctopuses," and those who want to negotiate peace, called "peacesquids". Despite the tense and precarious state of the world, high school students Koyama Kadode and Nakagawa Ouran live their lives with some semblance of normalcy. The focus of the story is not on the alien invasion but on human nature and growing up in a turbulent and uncertain world."
