In many parts of the world, unusually large unidentified objects have been discovered, and of course some giant human skeletons have been found, and it is speculated that these giants are between three and four meters tall, and the tallest giant is five meters.

As a vanished giant, of course the author doesn't know what kind of environment they live in, most of the stories in the novel are the author's illusions, I hope you can like it! )
