Due to his parents' overseas work, Niwa Makoto moves to the city to live with his 39-year-old aunt Touwa Meme. The boy, who expected to live a dream life with a harem, is instead confronted with a hitherto unknown relative: Meme's daughter Erio, a strange recluse with a fascination for aliens. Makoto has since been trying to help her open up, even as he gets to know more about his cousin.
