Kenji Tomosaka moved to this coastal town when he was a child. At that time, the sea spread in front of him was shining like lamune, reflecting the sunlight of the summer. There, he met a girl. Her name is Nanami Konoe, who lived next door. Her room is only 1 to 2 meters away beyond the veranda. Their rooms were so close as if they were within their arms’ reach. As the time passed, the seasons came round, their memories have been accumulated with time. They think of their normal lives and common relationship as precious things. The sun begins to shine strongly, cicadas begin to buzz, and the sky clears up… Here comes the summer, again! For Kenji and Nanami, it is normal summer, but it has special meaning…

Like snow falling in summer, like a cicada lamenting the coming of winter... In a town watched over by a whale in the sky... the extraordinary is made ordinary. Spectacles that could never be given form are instead given flesh and soul. And in their midst, the story of a miracle that comes to pass in this town of miracles incarnate... For Kuonji, this newly-discovered vision is a thing of wonder and fright – a sentiment not shared by his peers. Under its watchful gaze, Kuonji chats with and hangs out with his somewhat unusual friends. Whether it's with Nina and her striped panties, cat-loving Sacchan, the strange alien Allen or a variety of other busty, skimpily-dressed babes, Kuonji finds himself in the middle of ecchi situations galore! Welcome to the world of Final Examination Kujira.
