At 3:00 a.m. on September 14, 2023, in the 21st century, Earth's satellites detected a massive comet slowly heading toward the planet! Its size and density were so immense that if it struck Earth, the planet would be destroyed and humanity wiped out! For the first time, countries around the world united to face this catastrophe. They used nearly all of Earth's resources and nuclear weapons to destroy the comet, but its destruction triggered a rift in space-time, causing a tiny number of people to transmigrate to other universes! Our protagonist was one of them! And so begins the story of The Otherworldly Demon!
