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.
it is true that this anime has one of the best art (drawing and coloring) i've ever seen. the characters look awesome most especially the female characters where you can't help but notice that almost all the characters have distinct lips and blush. haha.
as for the story, i've finished the anime without really knowing what the point of the story was. nevertheless, it was still interesting to watch as each episode are cut at unexpected events and you just can't help but be curious of what's about to happen next. the characters are pretty unique as well. overall, i don't think it's one of the bests but it was good enough for me to stick onto watching 'till the end.
