After being summoned to another world as a hero, I finally defeated the Demon King.

I returned to the Earth I had dreamed of for so long, but something was strange.

“Code C!! The anomaly has escaped!”

“Eeeek! Everyone, run!!”

W-Who is that man!? He suddenly appeared out of nowhere!

“T-This is a Code S situation!!!”

Everyone points at me and calls me an anomaly. Apparently, the Earth I knew has changed quite a lot.
