Shin chan Me and the Professor on Summer Vacation The Endless Seven-Day Journey

Hiroshi has to travel to Kyushu on business, so the Nohara family of four chose to visit Misae, Kumamoto, a former friend of the family.
They reach Kumamoto Station, on their journey towards Assou. The stranger gives them a camera with a bizarre state. He demands witnesses.
Shinnosuke can take in the mountains of Assou and the fields of the summer season with his camera at his feet. The scene is filled with creatures that he would have never seen in Kasukabe. The town has many people who could help him, as well as brand new friends to make.
It is said…don’t they look an awful lot like the kids he was raised with at home?

In a cool summer night, Shinnosuke spots a gigantic creature outlined against the light of the full moon. Next to the creature is a stranger with an enormous smile.
This is the man who gave him the camera at the station…
He refers to himself as Professor Akuno. Assou has been witness to many weird events because of this confrontation.
