This work is a fanfic based on Ultraman, describing a story that will take place on Earth a thousand years later. In 2100 AD, for unknown reasons, the sun went out in an instant, the earth's temperature plummeted to minus 40 degrees, and the earth was swallowed up by endless darkness. In just a few months, the earth's population dropped to one tenth. People huddled in the darkness with only a little light and supplies. When everyone was about to despair, the sky shed sunlight, so people walked out and knelt down, with tears in their eyes and hands clasped together to thank God. Then people were surprised to find that their bodies had undergone tremendous changes after being exposed to sunlight. Every cell seemed to have been transformed and gained superhuman strength. The power of light filled the whole body. When people tried to activate this power, even their appearance would change. It transforms into a humanoid body with a smooth metallic skin. There are various line patterns on the body, and it has sculptural muscles and powerful strength. The head has two big eyes and a sharp mouth. Each person has a different appearance after the transformation. People call this brand new attitude "Ultraman" and believe it is God's salvation after experiencing disaster. So living humans united to rebuild a brand new continent, the "Continent of Light," and now it is 3100 AD, and all of us live on this continent.
