The story revolves around a highschool boy named Niwa Makoto. He lives with his aunt’s family since his parents are away on business. It is there where he meets his mysterious cousin of the same age Touwa Erio — who happens to tie a futon mattress around her upper body and is a self-proclaimed alien. Her staple food is pizza. Erio had been missing for half a year and was found floating in the sea. She doesn't remember anything about what happened during that period of time, but she began to think that it was the act of an alien and wanders the neighbourhood wrapped in the futon.
the story is a bit confusing at the beggining but the story sink in together very well later through some flash back episodes. It was funny and well thought through, every character was uniqe with a characteristic personality and as I watched the episodes I started to like those characters.
If you are bored of supernatural powers, never ending fights, robots and magic and you want some easy going, funny anime that has a nice story then this anime is a good choise :)
