Hiroshi has to travel to Kyushu for business. So the Nohara family of four decided to spend time with Misae, Kumamoto, a old friend from childhood.
They reach Kumamoto Station, on their journey towards Assou. An unknown person offers them a camera in a strange condition. He demands witnesses.
With his brand new camera in hands, Shinnosuke can enjoy his time in the gorgeous Assou mountains and fields to the max. Shinnosuke was shocked to encounter creatures in the Assou fields and the mountains, which were not found in Kasukabe. Additionally, the townspeople will help him along with new friends to make.
That said…don’t the kids appear quite a bit like children he has at home?
An evening in the summer heat, Shinnosuke spots a gigantic creature outlined against the light of the full moon. An unsettling, smiley man is next to the creature.
This man also gave the camera to him at his station…
The man is known as Professor Akuno. After this meeting, more and more strange things start occurring in the vicinity of Assou…
