While you are on your way home from school, you are looking down at your phone because it's boring to walk without doing anything. Your phone shows that many people have theorized that there might be a world similar to ours somewhere in the universe. Suddenly, a pickup truck rushes from the road and crashes into you, causing you to die instantly on the spot.

You open your eyes and find yourself in a city somewhere, but the pain from the accident you just had seems to have vanished as if nothing happened. After looking around for a while, you see creatures that resemble animals walking on two legs around the city. Some of them are walking in pairs. You look to the right and notice a large sign floating in the air that says, "Welcome to Terra Nova City!"
