电波女与青春男

故事的主角是将“青春点数”分配到自己的行动和相关的事情上、有时欢喜有时忧愁的少年丹羽真，及把被子卷在身上、自称外星人的“电波女”（却是美少女）的藤和艾莉欧（藤和エリオ）。作品以这二人为中心，展开了有点奇怪、却又非常清爽的青春故事。

宇宙人が見守ると噂される町で、叔母の家に住む事になった主人公・丹羽真。彼を待ち受けていたのは、布団で簀巻きになった電波女だった! しかも、地球は狙われているだの、自分は宇宙人の血を引くだの、言動も電波そのもの。だが学校では天然癒し系なリュウシさんや、モデル体型のコスプレイヤー前川さんと出会って青春を満喫……してみたり。 宇宙への憧れにのせてお送りする、ちょっと不思議な物語。

Makoto Niwa meticulously tallies the amount of positive and negative youthful experiences he engages in as if to grade his own life. When his parents go overseas, he moves to a new town to live with his aunt, welcoming the change and ready for a fresh start. However, as ordinary as he had imagined his adolescence to be, he could never have taken the existence of an enigmatic long-lost cousin into account.

Upon moving into his aunt's house, he discovers the cousin he never knew about: Erio Touwa. Despite being Makoto's age, she couldn't be more different: Erio chooses to wrap herself in a futon all day rather than to go to school. She even claims to be an alien, and with a speech pattern and personality to back it up, any chance of Makoto's dreamt-of normal life is instantly tossed out the window.

As he meets a string of other eccentric girls in town, Makoto must face the possibility of seeing his youth points in the red. However, he might be surprised by how thrilling an abnormal youth can be.
