In the future, aliens coexist freely with mankind on Earth. One such alien is NieA, a lazy yet spirited girl who wastes away her days while living with the studious Mayuko. And life isn't easy... Mayuko is always short on food money, the spa where she works is about to go bankrupt and Mayuko's alien-crazy friend Chiaki is obsessed with NieA.
A girl named Yuuka encounters a being from the depths of the Earth named Chii-chan (a pun of 'Chiteijin,' the Japanese word for underground-dweller), and an alien named Ucchan (a pun of 'uchuu jin,' or 'alien'.) The two beings begin living with Yuuka who promises to protect them.
When the ragtag crew of the Carlvinson saw a spaceship crash land on a planet below, they had no idea they’d stumble across a now-orphaned baby girl!

The very unorthodox “parents” and “extended family” of the Carlvinson will watch Corona grow from a baby to a young child, and will participate in mock dragonfly rescues, family field days, and more! But soon a transmission reveals that someone is coming to retrieve Corona – will Corona’s adopted family lose her forever?

With bizarre machines threatening the city, it seems they have little choice but to pilot the Z Mind robot. Yet keeping their little sister Satsuki out of trouble, dealing with dad's nagging, uncovering the identity of Ayame's mysterious savior and contending with the freaky aliens might prove a little too much for anyone to cope with!
Three years ago the aliens invaded Tokyo. Nothing was ever the same again. But after a while, even impending doom starts to feel ordinary.

Maybe it’s time to try something unconventional. Meanwhile, Kadode Koyama is in high school. She and her best friend avidly track the aliens’ movements on social media and less enthusiastically study for college entrance exams. When the end of the world is overhead, you learn to take things one step at a time.
