Earthlings

Natsuki isn't like the other girls. She has a wand and a transformation mirror. She might be a witch, or an alien from another planet. Together with her cousin Yuu, Natsuki spends her summers in the wild mountains of Nagano, dreaming of other worlds. When a terrible sequence of events threatens to part the two children forever, they make a promise: survive, no matter what.

Now Natsuki is grown. She lives a quiet life with her asexual husband, surviving as best she can by pretending to be normal. But the demands of Natsuki's family are increasing, her friends wonder why she's still not pregnant, and dark shadows from Natsuki's childhood are pursuing her. Fleeing the suburbs for the mountains of her childhood, Natsuki prepares herself with a reunion with Yuu. Will he still remember their promise? And will he help her keep it?
