After being asleep for a thousand years, I found out that extraterrestrial creatures had bred humans for their nourishment. In reaction to this, I set on a mission to wipe out these monsters with my companions, including my wife, a fox demon, a reliable witch, a royal-blooded princess, the Yin and Yang Patriarch, the wise Jian, my tech-savvy sister, a close pseudo-relative, and a servant wearing animal-like ears. To my surprise, the ruling Demon Queen had granted me the ownership of Earth. Would I choose to bask in leisure or lead a war against God?
