This book takes place in an inconspicuous town near a mountain. Due to an abnormality in the earth's core (the cause is actually unknown), there are many magical and incredible animals and things in the town.
This year's summer vacation, two innocent and kind-hearted outsiders appeared in the town. They accidentally discovered the existence of these magical things, and started a series of absurd, funny, and crazy adventure stories. These novel adventure stories about them have also led to a series of funny and touching emotional stories.
Overall, this book is an absurd, funny, and extremely imprecise adventure story.
