[Various types of adventure stories] [Multiple worldviews] [Fast plot development] In the distant future where productivity is highly developed, humans can capture optical information of what happened in history in distant space. The history of seven different moments has been captured and many historical worlds have been established based on this. These worlds include resistance uprisings, teenagers' summer adventures, apocalyptic survival on high-rise trains and ships, primitive family epics, and stories from the age of gods even further back. As a former astronaut, the protagonist constantly interprets these worlds while avoiding the pursuit of evil forces in reality.
