Erio is [Makoto](https://anilist.co/character/40874)'s first cousin. One day, she mysteriously disappeared for six months, with no memory of what happened during that time. At the same time, she began having an extreme fascination with aliens, believing herself to be an alien investigator monitoring humans. ~!Following an incident where she broke her leg whilst trying to fly on her bike, she constantly wraps herself inside a futon.!~

Makoto Niwa just moved to the city to live with his aunt Meme after his parents were reassigned to work overseas. He is perfectly fine with that, saying it will give him the chance to live the dream life of an adolescent boy. He keeps track of the things he does by assigning "points" to them—positive or negative—and adds them up on a regular basis to grade his adolescent life. 
 
And then he discovers Meme has a secret daughter (and self-proclaimed alien) named Erio. He finds her rolling around by the front door of Meme's house wrapped up in a futon. It is then he realizes that his dream adolescent life will not come true, and begins a life of experiences that are out of this world.
