Hiroshi needs to visit Kyushu to attend a business meeting, and so the Nohara whole family decided to spend time with Misae, Kumamoto, a childhood friend.
They arrive at Kumamoto Station, on their journey towards Assou. A stranger offers them a camera in a odd condition. He demands witnesses.
Shinnosuke is able to enjoy the mountains of Assou and the fields of the summer season with his camera at his feet. The landscape is also brimming with animals that he could have never seen in Kasukabe. Also, there are locals to help and new friends to form.
They look a lot like his children who are from his their home?
Shinnosuke spotted a gigantic creature silhouetted against the full moon in a cool summer evening. An unsettling, smiley man stands next to the beast.
A similar man handed the camera back to him when he arrived at his station...
He refers to himself as Professor Akuno. Assou is witness to more bizarre events as a result of this encounter.
