Chapter 0
Being transported to another world... isn't something you want to experience.
I can say that with certainty, because I was transported to another world once, nearly died of old age there, and only made it back to Earth thanks to a gamble at the very brink of death.
Being transported to another world is not something worth experiencing.
Still, somehow, I made it back to Earth. I thought I could finally live a peaceful life.
“Kieeeeeeeek!!!”
Why had a Gate opened on Earth?
A Gate, of all things. Why were monsters from the other world I knew so well coming through it?
Why had things turned out this way?
Why had another world followed me?
What had I done wrong?
Why on earth?
