On a certain summer day, Keisuke Amakawa lost consciousness while watching a movie at a cinema, and when he came to, he found himself transported to another world. The bewildered Keisuke was surrounded by magnificent nature and quickly became lost.

There, he met a blacksmith, and as they talked, he realized that the story was the same as a game he had been playing, and thus understood he had been transported to the world of the movie. Not knowing how to return, Keisuke decided to live in the game world.
