Comet (12 years old in human years) is the princess of the Harmonica Star country and was to meet the prince of the Tambourine Star country at a ball where he'd pick a bride. But he isn't there and so Comet is sent to Earth to find him. He'll be known by the starlight in his eyes. She finds the Earth and she loves the people she meets there. Meanwhile, Princess Meteor of the Castanet Star country also arrives on Earth in search of the prince. Comet's companion is a little puppy with a star at the end of his tail named Rubba Ball. Of course, Comet was not the first to visit the Earth and love it, another before her did as well and married. Her pet (a white cat with bunny ears and a tiny heart on her tail named Bunny) continued life as a kind of fairy in the forest. Comet's power is drawn from the stars of her home and is channeled through her baton; she also wears a special pendant from where Rubba Ball immerges, and with which she can detect and find the prince.

However, his cover is blown, and the spy reveals himself to be an alien in disguise.

As a member of the government agency known as the Super Population Research Laboratory, Jirou has the dual task of protecting superhumans that defend humanity and disposing of any deemed too dangerous to live.

Under mysterious circumstances, Jirou has betrayed the agency, and is now a fugitive on the run. As he skulks through the rainy back alleys of Shinjuku, he is pursued by the very same superhumans that he himself once recruited.

At first glance, Ibara Naruse and her friends Aoi Fukasaku and Taeko Nomura look like average, carefree high school students. But the streets they walk on, their destination, and their surroundings are anything but normal. As they continue forward, the trio find themselves stepping deeper into an uninhabitable version of Tokyo, one that has been ravaged by a nuclear disaster 20 years ago. As part of the Dispatch 3rd Special Force Coppelion, known as the Health Care team, Ibara, Aoi, and Taeko are supported by the Japanese Ground Self-Defense Force (JGSDF) and Colonel Onihei Mishima as they scour the eerily silent streets for survivors. Finding the last remaining humans and having them evacuated by the JGSDF's helicopters is a daily occurrence for the girls. But as their work progresses, Ibara and her friends start to question their own humanity—namely, how they themselves are able to survive in Tokyo without any protective gear.
