I was just a normal boy attending high school until I found myself in a different world vastly different from my own, transported into it by getting hit by a truck. I spend a year using my desire to return home as a means to become strong enough to save the world from the Demon Lord. Now, I come back to find out everyone I expected to welcome me home.. either gone or no longer wants to be around me. I now set my goal to destroy the world without a thought, not care in the world.
