- Description from novelbuddy

The world’s top ten conglomerates had joined forces to create a programme where the crew had quietly evacuated all the people from a city, leaving behind only Raymond and his family, who were kept in the dark. Their purpose was to see this child, who had emerged from the slums of America, get humiliated.

This story is centered around the man named Yi Ji-Hyuk, who has spent 1000 years in a Medieval Western fantasy-like world before returning back to the modern-day Earth. When he returns, he finds that his home is facing monster threats, and that humans with superpowers have appeared to protect the innocent people of Earth.
