"The Observer" is the 3rd fragment of The Mystic Archives of Dantalian light novel, volume 5. The special chapter is also labeled as "The Abyss Gazes Also Into You".

A man finds an unusual photo album which depicts an alien world. A black-haired girl warns him to check only one page per day.[1]


The man wants to stay alone and watch the world by the window. One day, he sees a beautiful book in a used bookstore. The photo album has a cover that reads “The World”. Before he realizes, the man had picked it up. He buys it and almost runs out of the store. He’s stopped by an unusual black-haired girl. She warns him to look only one page per day. The same warning is written on the cover.

The man returns to his home. He opens the photo album. He sees the image of a stormy red sea and a sky with black clouds and lightning, a terrible world. The next day, the man checks the next page. The sea is calmer, the clouds scattered, the sunlight reaching the water, a moon in the sky. The next day, the man sees a beautiful sea, primitive animals swimming, algae floating on the water. The man realizes that the book shows the history of the planet.

Several months passed. The world inside the photo album keeps changing. Plants and animals reach the land. Animals become larger and more intelligent. Creatures similar to dinosaurs appear. Birds, fishes, beasts, plants and trees develop. However, the inhabitants of that world are different from the inhabitants of the world where the man lived. Their behavior, lifestyle and appearance are unfamiliar. The man has an idea.

After several months, the man’s life changed. His inventions quickly spread around the world. His company succeeds. His original technologies are praised. The government awards him. He becomes famous and rich. The man had invented incredible things based on the appearance of the unique animals depicted in the photo album. If evolution continues in that book, the man would borrow the science, the ideas and the technology developed by the upcoming human civilization. The man would go down in history as a great inventor.

The man turns the pages, one after the other. People appear in the photo album. They form tribes, then countries. Science and technology are developed. They learn how to reach the skies. However, the progress leads to negative effects. Plants and animals die. Resources are exhausted. The nations fight to possess them. The weapons become more deadly. As an observer, the man doesn't care. He keeps turning the pages. Eventually, the people inside the photo album invent huge bombs. The man examines the last page. He sees a bright flash. According to newspapers, the man burned to death from a fire that arose for unknown reasons. The black-haired girl peers into his room. Only the photo album remains. The last page depicts the ruins of a civilization. The girl grabs the book. She calls the deceased man a liar.[1]
